The back pack unit 15 is rotatably supported with respect to the main body frame 13. In addition, the base 211 is provided with a fastener 215 for fastening to a fastening hole 134 provided in the main body frame 13, and the main body can be obtained by fitting the fastening 215 into the fastening hole 134. A back pack unit 15 is fixed to the frame 13.

  In the base portion 211, a payout mechanism portion 202 is disposed so as to bypass the protective cover portion 212. That is, a tank 221 opened upward is provided at the top of the back pack 201, and game balls supplied from the island facilities of the game hall are sequentially replenished to the tank 221. A tank rail 222 that is gently inclined toward the downstream side is connected to the lower side of the tank 221, and a case rail 223 that extends in the vertical direction is connected to the downstream side of the tank rail 222. A payout device 224 is provided at the most downstream portion of the case rail 223. The game balls paid out from the payout device 224 are supplied to a game ball distribution unit 225 provided in the base portion 211 of the back pack 201 through a payout passage (not shown) provided on the downstream side of the payout device 224.

  The game ball distribution unit 225 has a function of distributing the game balls paid out from the payout device 224 to any one of the upper plate 33, the lower plate 34, and a discharge passage described later, and the inner opening 226 has been described above. The center side opening 227 communicates with the lower plate 34 via the main body side lower plate passage 123 and the front door side lower plate passage 52 through the main body side upper plate passage 122 and the front door side upper plate passage 51. The outer opening 228 is formed to communicate with the discharge passage.

  A backpack substrate 229 is installed in the dispensing mechanism unit 202. The back pack substrate 229 is supplied with, for example, a main power of AC 24 volts and is turned on or off by a switching operation of the power switch 229a.

  A discharge passage board 203 and a control device collective unit 204 are attached to the lower end portion of the base portion 211 so as to sandwich the lower end portion in the front-rear direction. The discharge passage board 203 is formed with a discharge passage 231 opened rearward on the surface facing the control device assembly unit 204, and the open portion of the discharge passage 231 is closed by the control device assembly unit 204. The discharge passage 231 is formed so as to discharge the game ball to the island facility or the like of the game hall, and the game ball led out to the discharge passage 231 from the above-described collection passage 151 or the like passes through the discharge passage 231 so as to be pachinko. It is discharged outside the machine 10.

  The control device assembly unit 204 has a horizontally long mounting base 241, and a payout control device 242 and a power source and launch control device 243 are mounted on the mounting base 241. The payout control device 242 and the power supply / launch control device 243 are arranged so as to overlap each other so that the payout control device 242 is behind the pachinko machine 10.

  The payout control device 242 accommodates a payout control board for controlling the payout device 224 in the board box 244. The payout command signal from the payout control device 242 to the payout device 224 is relayed by the backpack substrate 229 described above. The payout control device 242 is provided with a state return switch 245. For example, when the state return switch 245 is pressed when a payout error such as a ball jam in the payout device 224 occurs, the ball jam is eliminated.

Further, the power and launch control device 243 is provided with a RAM erase switch 247. This pachinko machine 10 has a function to store and store various data so that even if a power failure occurs, it maintains the state at the time of the power failure, and when it recovers from the power failure, it can be restored to the state at the time of the power failure. It has become. Therefore, for example, when the power supply is turned off in the normal procedure, as in the case of the game hall being closed, the state before the turn-off is stored and retained. It is like that.

  Note that the RAM erasure switch 247 is not limited to the configuration provided in the power supply and launch control device 243, and may be configured in the main control device 162, for example.

<Electric configuration of pachinko machine 10>
Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 14, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The main control device 162 is provided with a main control board 301 and a power interruption monitoring board (power failure monitoring board) 302. An MPU 311, a system clock circuit 312, a hard random number clock circuit 313, and a modulation circuit 314 are mounted on the main control board 301. The MPU 311 temporarily stores various control programs executed by the MPU 311 and a ROM (nonvolatile storage means) 315 that stores fixed value data, and various data when the control program stored in the ROM 315 is executed. RAM (volatile storage means) 316, a counter circuit 317, and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated. Note that some or all of the MPU 311, the ROM 315, and the RAM 316 may be provided as separate chips.

  The MPU 311 is provided with an input port 311a and an output port. Note that an input / output port may be provided and input / output may be appropriately changed in the MPU 311. The same applies to other MPUs described later.

  Connected to the input port 311a of the MPU 311 are a power interruption monitoring board 302, a payout control board 322 provided in the payout control device 242, and other sensor groups (not shown). In this case, a power supply and launch control board 321 is connected to the power interruption monitoring board 302, and power is supplied to the MPU 311 via the power interruption monitoring board 302.

  As a part of the switch group, a plurality of detection sensors provided in the ball entering portion such as the operation port 84 and the variable winning device 83 are connected, and the MPU 311 of the main control device 162 performs the ball entering judgment of the ball entering portion. Is called. Further, the MPU 311 performs the jackpot occurrence determination based on the entrance to the operation port 84 in the entrance portion.

  The system clock circuit 312, the hard random number clock circuit 313, and the modulation circuit 314 will be described later.

  Here, an electrical configuration for performing control related to a game in the MPU 311 will be described with reference to FIG.

  The RAM 316 is provided with various counter areas, and the MPU 311 uses the various counter information stored in the counter area and the counter information of the counter circuit 317 during the game to draw the big hit lottery and the first specific lamp unit 93. Setting of emission color, setting of symbol display of the symbol display device 91, and the like are performed.

  Specifically, the jackpot random number counter C1 used for the jackpot lottery, the jackpot type counter C2 used for determining the jackpot type such as the probability variation jackpot or the normal jackpot, and the reach when the symbol display device 91 is changed. The reach random number counter C3 used for the lottery and the variation type counter CS for determining the period for switching the color displayed on the first specific lamp unit 93 and the symbol variation display time in the symbol display device 91 are used.

  Here, the counter circuit 317 is a circuit dedicated to updating the jackpot random number counter C1, and the jackpot random number counter C1 is updated when a clock signal is input to the counter circuit 317. On the other hand, counters C2, C3 and CS other than the jackpot random number counter C1 are stored in various counter areas of the RAM 316, and the other counters C2, C3 and CS receive an update command from the MPU 311. Updated based on.

  The other counters C2, C3 and CS will be described in detail. Each of the other counters C2, C3 and CS is a loop counter which adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value. Yes. Each counter is updated by a process necessary for progressing the game, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 316. The RAM 316 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, game balls to the operation port 84 are stored. The values of the jackpot type counter C2 and the reach random number counter C3 are stored in time series according to the entry history.

  In detail, the jackpot type counter C2 is configured to increment one by one within a range of 0 to 49, for example, and return to 0 after reaching the maximum value (ie 49). In the present embodiment, the jackpot type counter C2 determines whether to change to a probable change state or a normal state after the jackpot has ended.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 determines whether or not to execute reach when the game result is out of place.

  For example, the variation type counter CS is incremented one by one within a range of 0 to 240, for example, and reaches a maximum value (that is, 240) and then returns to 0. The switching display time as a period for switching the color displayed on the first specific lamp unit 93 is determined by the variation type counter CS. This switching display time corresponds to the symbol fluctuation display time of the symbol display device 91. The variation type counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the variation type counter CS is acquired at the time of starting the switching of the color displayed on the first specific lamp unit 93 and determining the variation pattern at the time of starting the variation of the symbol by the symbol display device 91.

  The jackpot random number counter C1 will be described in detail. For example, the jackpot random number counter C1 is incremented one by one within a range of 0 to 676, for example, and reaches a maximum value (that is, 676) and then returns to zero. When a game ball enters the operation port 84, the MPU 311 accesses the counter circuit 317, acquires the value of the jackpot random number counter C1 at that time, and further stores the acquired value of the jackpot random number counter C1 in the RAM 316. Store in the ball storage area.

  At the start of one game round, the MPU 311 of the main control board 301 uses the values of the counters C1 to C3 and CS stored in the holding ball storage area to win a big hit lottery or the first specific lamp unit 93. The switching time of the displayed color is determined, and the information on the lottery result and the switching time determined here are transmitted to the sound lamp control device 143 as a game turn command. The sound lamp control device 143 determines the effect contents of the corresponding game times, such as the variation pattern in the symbol display device 91 and the presence / absence of reach, based on the game times command.

  In addition to the above counters, the RAM 316 is provided with a second specific lamp random number counter used for a lottery to determine whether or not to open the electric accessory provided in the operating port 84. The value of the second specific lamp random number counter at that time is acquired at the timing when the winning to the gate 85 occurs, and a lottery is executed as to whether or not to open the electric accessory based on the acquired value. .

  Returning to the description of FIG. 14, the power interruption monitoring board 302, the payout control board 322, and the relay terminal board 323 are connected to the output port of the MPU 311. Various commands such as a prize ball command are output to the payout control board 322. Through the relay terminal board 323, the above-mentioned command for gaming etc. is output from the main control board 301 to the voice lamp control board 324 provided in the voice lamp control device 143.

  The power interruption monitoring board 302 relays between the main control board 301 and the power source / launch control board 321 and monitors a DC stable voltage of 24 volts, which is the maximum voltage output from the power source / launch control board 321. When this voltage is 22 volts or more, an HI level signal as a non-interruptible signal (first information) is output (transmitted) to the main control board 301. When this voltage is less than 22 volts, the power is shut off. And a LOW level signal as a power failure signal (second information) is output (transmitted) to the main control board 301. The main control board 301 confirms the input of the LOW level signal in a predetermined manner, and executes a power interruption process (power failure process) to be described later based on the confirmation result.

  The payout control board 322 controls payout of prize balls and the like by the payout device 224. The MPU 331 that is an arithmetic unit includes a ROM 332 that stores a control program executed by the MPU 331, fixed value data, and the like, and a RAM 333 that is used as a work memory or the like. Note that some or all of the MPU 331, the ROM 332, and the RAM 333 may be provided as separate chips.

  The MPU 331 of the payout control board 322 is provided with an input port and an output port. A main control board 301, a power and launch control board 321, and a back pack board 229 are connected to the input side of the MPU 331. Further, the main control board 301 and the back pack board 229 are connected to the output side of the MPU 331.

  The power supply and launch control board 321 includes a power-on power supply unit 321a and a launch control unit 321b. The power-on power supply unit 321a is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control board 301, the payout control board 322, etc., and the generated operating power is indicated by a double line arrow. Supply to the main control board 301, the payout control board 322, etc. through the path. As its outline, the power-on power supply unit 321a takes in the AC 24 volt power supplied via the back pack substrate 229, and DC + 12V power for driving various sensors, motors, etc., DC + 5V for logic Electric power and the like are generated, and these DC + 12V power and DC + 5V power are supplied to the main control board 301, the payout control board 322, and the like.

  The launch control unit 321b is responsible for launch control of the game ball launching mechanism 110 in accordance with the operation of the game ball launch handle 41 by the player, and the game ball launching mechanism 110 is driven when predetermined launch conditions are met. The

  The power source and launch control board 321 is equipped with a power source unit 321c for power interruption. The power supply unit for power interruption 321c is composed of a capacitor. When the power of the pachinko machine 10 is ON (when power is supplied from an external power supply), the power supplied from the power supply unit for power supply 321a is used. Charged. In addition, when the power of the pachinko machine 10 is in an OFF state or when a power interruption occurs such as when a power interruption occurs in a commercial power supply (when power supply from an external power supply is interrupted), the power supply unit 321c for electric interruption is discharged. Memory holding power is supplied to the RAM 316 of the main control board 301. Therefore, even in such a situation, the information stored in the RAM 316 is stored and held without being erased while the power for storing and holding is supplied from the power supply unit 321c for power interruption.

  Incidentally, the capacity of the power supply unit 321c for power interruption is ensured to be relatively large, and information stored in the RAM 316 before the power is shut off is retained within a predetermined period (for example, 1 day or 2 days). Further, the power interruption power supply unit 321c is not limited to a capacitor, and may be a battery, a non-rechargeable battery, or the like. In the case of a non-rechargeable battery, it is not necessary to charge the power supply means for power interruption when the power of the pachinko machine 10 is ON, but it is necessary to replace it periodically.

  The power supply and launch control board 321 is provided with a power supply unit for power interruption processing different from the power supply unit for power interruption 321c. In the power supply and launch control board 321, even after the DC stable 24 volt power supply becomes less than 22 volts, the power supply unit for the power interruption processing discharges, so that a sufficient time for execution of the power interruption processing described later is performed. During this time, the output of 5 volts, which is the drive power supply for the control system, is maintained at a normal value. Thus, the main control board 301 and the like can normally execute and complete the power interruption process.

  Further, the power supply and launch control board 321 is provided with an AC power supply unit 321d that outputs an AC voltage. The AC power supply unit 321d outputs the + 24V AC voltage supplied from the commercial power supply as it is.

  Note that the AC power supply unit 321d is not limited to this configuration, and may include a full-wave rectifier circuit as waveform shaping means for adjusting the voltage waveform. In this case, the output waveform of the + 24V AC voltage supplied from the commercial power supply is rectified in one direction.

  The sound lamp control board 324 controls the various lamp units 23 to 25 (specifically, the annular lamp unit 23, the error display lamp unit 24, the prize ball lamp unit 25), the speaker unit 26, and the display control device 325. . The MPU 341 that is an arithmetic unit includes a ROM 342 that stores a control program executed by the MPU 341, fixed value data, and the like, and a RAM 343 that is used as a work memory or the like.

  The MPU 341 of the sound lamp control board 324 is provided with an input port and an output port. The main control board 301 is connected to the input side of the MPU 341 by relaying to the relay terminal board 323. Based on various commands output from the main control board 301, various lamp units 23 to 25, the speaker unit 26, and The display control device 325 is controlled. The display control device 325 controls the symbol display device 91 based on a display command input from the sound lamp control board 324.

<Processing Configuration of MPU 311 of Main Control Board 301>
Next, each control process executed by the MPU 311 of the main control board 301 will be described. The processing of the MPU 311 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started by periodically interrupting the normal processing of the main processing, and a power failure to the NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by signal input. For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 16 shows an NMI interrupt process, which is executed when the power of the pachinko machine 10 is interrupted due to the occurrence of a power failure or the like. That is, when the power supply of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, a power failure signal is output from the power failure monitoring board 302 to the NMI terminal of the MPU 311, and the MPU 311 interrupts the current control and performs NMI interrupt processing. To start. In the NMI interrupt processing, the power failure flag is set in the power failure flag storage area provided in the RAM 316 in step S101, and this processing is terminated. Thereafter, when it is confirmed that the power failure flag is set in the normal processing described later, the power failure processing is executed.

<Timer interrupt processing>
FIG. 17 is a flowchart showing timer interrupt processing. The timer interrupt process is periodically started as described above. In this case, the present embodiment is configured to be activated at a cycle of 2 msec, but this cycle is arbitrary. However, since the timer interrupt processing is set to be executed repeatedly in a short cycle such as confirmation of power interruption signal or fraud detection signal, confirmation of various winnings, etc., other processing is set. It is preferably set shorter than the repetition period of the normal process described later.

  In the timer interrupt process, first, in step S201, a signal reading process is executed. In the signal reading process, information input to the input port 311a from the ball detection sensors provided individually for the general winning port 82, the variable winning device 83, the operating port 84 and the through gate 85 is confirmed, and the confirmation result To determine whether or not there is a ball entering each ball club. Specifically, input of a signal (for example, a LOW level signal) corresponding to not detecting a game ball in any one process is confirmed, and a game ball is detected in the subsequent two processes. When the input of a signal (for example, an HI level signal) corresponding to being performed is continuously confirmed, it is specified that a game ball has entered in the entrance corresponding to the detection sensor.

  After executing the signal reading process, in the subsequent step S202, the big hit type counter C2 and the reach random number counter C3 are updated. Specifically, the value of each random number counter is incremented by 1 and it is determined whether or not the added value is an upper limit value. If the added value exceeds the upper limit value, the counter value is set to the initial value.

  In this process, the jackpot random number counter C1 is not updated. The update of the big hit random number counter C1 will be described later.

  Thereafter, a start winning process is executed in step S203. In the start winning process, as shown in the flowchart of FIG. 18, first, in step S301, it is determined whether or not the operation port flag is stored in the operation port flag storage area of the RAM 316, whereby the game ball is operated as the operation port 84. It is determined whether or not a prize has been won (start prize). The operating port flag is stored when a winning of a game ball to the operating port 84 is confirmed in the signal reading process in step S201.

  If it is determined that the game ball has won the operating opening 84, in the subsequent step S302, whether or not the number N of the operation holding balls of the first specific lamp section 93 and the symbol display device 91 is less than the upper limit value (4 in the present embodiment). Determine whether. The process proceeds to step S303 on the condition that there is a winning at the operation port 84 and the number N of activated balls is less than 4, and 1 is added to the number N of activated balls. Note that the operation port flag is deleted after the process of step S303.

  In subsequent steps S304 to S306, processing for acquiring the value of the jackpot random number counter C1 at that time is executed. This process will be described together with the description related to the update of the jackpot random number counter C1.

  Thereafter, in step S307, the jackpot random number counter C1 acquired in step S305, and the jackpot type counter C2 and reach random number counter C3 updated in step S202 are used as the first free storage area in the reserved ball storage area of the RAM 316. Store in the area. Then, after the start winning process, the MPU 311 once ends the timer interrupt process.

<Main processing>
Next, the main process that is started upon resetting when the power is turned on will be described with reference to the flowchart of FIG.

  First, in step S401, a startup process associated with power-on is executed. Specifically, in order to wait for the slave control board (such as the payout control board 322) to be operable, it waits for about 500 msec, for example.

  In the subsequent step S402, it is determined whether or not 1 sec, which is a permission prohibition period, has elapsed since the start-up process in step S401. If 1 sec has not elapsed, the process of step S402 is executed again. This time measurement is performed by counting the number of times of processing in step S402. For example, if the time required to execute the process of step S402 again after making a negative determination in step S402 is 0.1 msec, the count value is 10,000 times, so that after the startup process of step S401 It is determined that 1 sec has passed. Note that the specific configuration of time measurement is arbitrary, and for example, time measurement may be performed using a real-time clock. If it is determined in step S402 that 1 sec has elapsed, the process proceeds to step S403.

  In step S403, access to the RAM 316 is permitted. Thereafter, in step S404, it is determined whether or not the RAM erase switch 247 provided in the power supply and launch control device 243 is turned on. In subsequent step S405, it is determined whether or not a power failure flag is stored in the RAM 316. In step S406, a RAM determination value is calculated. In subsequent step S407, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data is determined. The RAM determination value is a checksum value at a work area address of the RAM 316, for example. It is also possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 316 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 247. Therefore, if the RAM erase switch 247 is pressed, the process proceeds to steps S408 to S409. Similarly, when the information on occurrence of power shutdown is not set, or when abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to steps S408 to S409.

  In step S408, the used area of the RAM 316 is cleared to 0 (initialized), and in step S409, initialization processing of the RAM 316 is executed. Thereafter, interrupt permission is set in step S410, and the routine proceeds to normal processing to be described later.

  On the other hand, if the RAM erase switch 247 has not been pressed, a power failure is detected from the RAM 316 in step S411 on the condition that the power failure flag is stored and the RAM determination value (checksum value etc.) is normal. In addition to erasing the flag, the RAM determination value stored in the RAM 316 is erased in step S412. Thereafter, interrupt permission is set in step S410, and the routine proceeds to normal processing to be described later. Thereby, it returns to the state before power-off.

<Normal processing>
Next, normal processing will be described with reference to the flowchart of FIG.

  In the normal processing, in step S501, the variation type counter CS is updated. In a succeeding step S502, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 93 is executed. In the first specific lamp unit control process, jackpot determination, on / off control of a light source switch of an LED lamp disposed in the first specific lamp unit 93, and the like are performed. In the first specific lamp unit control process, the symbol display device 91 also sets the first symbol variation display.

  Specifically, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1. More specifically, it is determined whether or not the value of the jackpot random number counter C1 coincides with a winning value that is a predetermined jackpot winning. Further, the type of jackpot is determined based on the value of the jackpot type counter C2 (determining whether or not it is a so-called probable big hit). Further, based on the value of the reach random number counter C3 and the value of the variation type counter CS, the color switching display time displayed on the first specific lamp unit 93 and the variation display time of the first symbol are determined. Each time the on / off control of the first specific lamp unit 93 is started in the first specific lamp unit control process, the number of the operation reserved balls N is decremented by 1 and when the number of the operation reserved balls N is 0, the on / off control is performed. Does not start.

  After the first specific lamp unit control process, a special winning opening opening / closing process is executed in step S503. In the big prize opening / closing process, the big prize opening of the variable prize winning device 83 is opened or closed in the case of the big hit state. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. The determination as to whether or not the prescribed number has been won is made by checking the special prize counter. When either of these conditions is satisfied, the special winning opening is closed.

  Thereafter, in step S504, a second specific lamp unit control process for switching the color displayed on the second specific lamp unit 94 is executed. In the second specific lamp unit control process, switching of the display color in the second specific lamp unit 94 is started on the condition that a game ball has won the through gate 85. At this time, the display color switching time is also set. In addition, the color to be stopped and displayed is set based on the value of the second specific lamp random number counter acquired when the game ball wins the through gate 85. When a predetermined color is set as the stop-displayed color, the electric accessory attached to the operation port 84 is opened for a predetermined time after the stop display of the color.

  After step S504, a game ball launch control process is executed in step S505. In the game ball launch control process, the game ball launch mechanism 110 is once per predetermined period (for example, 0.6 sec) on condition that a launch permission signal is input from the launch control unit 321b of the power source and launch control board 321. Energize the solenoid. Thereby, the game ball on the launch rail of the game ball launching mechanism 110 is launched toward the game area. More specifically, the MPU 311 repeats “0” output and “1” output to the launch output port at a predetermined period on condition that the launch permission signal is input. While “0” is output to the firing output port, a non-firing signal is output to the power source and the firing control board 321, and the firing control unit 321b puts the solenoid in a non-excited state. On the other hand, while “1” is output to the launch output port, a launch signal is output to the power source and launch control board 321, and the launch controller 321 b sets the solenoid in an excited state.

  That is, the MPU 311 outputs a firing pulse signal to the power source and launch control board 321. The launch control unit 321b of the power source and launch control board 321 outputs a solenoid drive signal (drive voltage) obtained by amplifying the voltage of the launch pulse signal toward the solenoid, and moves the output shaft of the solenoid to the launch position and the accommodation position. Thus, the launch of the game ball is controlled.

  Thereafter, in step S506, it is determined whether or not a power failure flag is stored in the RAM 316. If the power failure flag is not stored, the process proceeds to step S507 to determine whether or not the next normal process execution timing has been reached, that is, an interrupt criterion that is set in advance by a plurality of timer interrupt processes from the start of the previous normal process. It is determined whether or not the number of times (specifically, twice) has occurred. Specifically, the number of timer interruptions is grasped by providing an interruption number counter in the RAM 316. Each time the timer interruption is activated, the counter value is incremented by 1 and the process of step S501 is executed. The value of the counter is cleared to 0 (initialized) at the timing immediately before the start. If the timer interruption process has not occurred for the number of interruptions, the process proceeds to step S508.

  In step S508, update processing of the variation type counter CS is executed. Specifically, 1 is added to the variation type counter CS, and when the value of the added variation type counter CS exceeds the upper limit value, it is cleared to 0 (initialized). Then, the update value of the variation type counter CS is stored in the corresponding buffer area of the RAM 316.

  Thereafter, the process proceeds to step S506. Thereafter, the above-described processing is repeated from the start of the previous normal processing until the timer interrupt processing occurs for the interrupt reference count, and when the interrupt reference count is reached, the processing returns to step S501. That is, when the power failure flag is not stored, the processing from step S501 to step S505 is repeatedly executed at a cycle of 4 msec. Note that the period is not limited to 4 msec as long as the progress of the game can be well controlled.

When the power failure flag is stored, the power failure process after step S509 is executed. That is, in step S509, the timer interrupt process is prohibited, and then the RAM determination value is calculated and stored in step S510. After the access to the RAM 316 is prohibited in step S511, the power supply is completely shut off and the process is performed. Continue infinite loop until no longer runs.
<About update of jackpot random number counter C1>
Next, updating of the jackpot random number counter C1 will be described with reference to FIGS. FIG. 21 is a block circuit diagram showing the configuration of the hard random number clock circuit 313 and the modulation circuit 314.

  As shown in FIG. 14, the main control board 301 includes a system clock circuit 312 that outputs a system clock signal and a hard random number clock circuit that outputs a hard random number clock signal used for updating the jackpot random number counter C1. 313 are provided. Both are electrically connected to the power supply and launch control board 321 via the power interruption monitoring board 302. Further, both are electrically connected to the MPU 311.

  The system clock circuit 312 is an oscillation circuit including a crystal resonator, and outputs a system clock signal to the MPU 311 in a situation where power is supplied from the power source and the launch control board 321. The MPU 311 performs a process necessary for the progress of the game and synchronizes with other hardware by operating a plurality of elements simultaneously with the input of the system clock signal as a reference.

  The hard random number clock circuit 313 outputs a hard random number clock signal to the MPU 311 in a situation where power is supplied from the power source and the launch control board 321. Based on the input of the hard random number clock signal to the MPU 311, the jackpot random number counter C1 is updated.

  Specifically, the jackpot random number counter C1 is set to be updated in synchronization with the input of the hard random number clock signal to the MPU 311 without being synchronized with the input of the system clock signal to the MPU 311. Specifically, the counter circuit 317 is configured so that only the hard random number clock signal is input, and the value of the jackpot random number counter C1 is changed by the counter circuit 317 synchronizing with the rising of the hard random number clock signal. One is added. That is, the other counters C2, C3, and CS are updated by timer interrupt processing or normal processing executed by the MPU 311, while the jackpot random number counter C1 is not updated by software processing in the MPU 311 but is a dedicated counter. Updated by circuit 317. The system clock signal that triggers the operation of the MPU 311 and the hard random number clock signal that triggers the operation of the counter circuit 317 are independently input to the MPU 311. Thereby, the update process of the jackpot random number counter C1 and other processes related to the progress of the game are executed in parallel. Therefore, the processing load on the MPU 311 can be reduced. Further, since the big hit random number counter C1 is updated without being affected by the software processing, the illegal action such as specifying the value of the big hit random number counter C1 in synchronization with the execution of the predetermined software processing and the illegal change such as rewriting the update program. Action can be suppressed.

  Here, the update timing of the jackpot random number counter C1 is the rising timing of the hard random number clock signal. The hard random number clock signal is set to have a different period from the system clock signal and not to be synchronized with the system clock signal.

  As shown in FIG. 21, the hard random number clock circuit 313 includes a frequency conversion circuit 401 that converts the frequency of the AC voltage, and a signal conversion circuit 402 that converts the AC waveform into a pulse signal.

  The frequency conversion circuit 401 is electrically connected to the AC power supply unit 321d through the power interruption monitoring board 302. When an AC voltage is input from the AC power supply unit 321d, the frequency conversion circuit 401 converts the frequency of the AC voltage to a specific frequency (for example, 300 Hz) and directs the converted AC voltage to the signal conversion circuit 402. It is configured to output.

  Specifically, the frequency conversion circuit 401 includes a local oscillation circuit 401a and a mixer circuit 401b. The local oscillation circuit 401a is composed of, for example, a CR oscillation circuit having a resistor and a variable capacitor (hereinafter simply referred to as a variable capacitor), and an AC voltage having a frequency corresponding to the resistance value and the capacitance of the variable capacitor is supplied to the mixer circuit 401b. It is configured to output toward.

  The mixer circuit 401b includes a first input terminal to which an AC voltage from the CR oscillation circuit is input, a second input terminal to which an AC voltage supplied from the AC power supply unit 321d is input, and an output terminal. Based on the fact that alternating voltages having different frequencies are input to the first input terminal and the second input terminal, an alternating voltage having a frequency difference between the two is output.

  Here, the CR oscillation circuit has a switch for changing the capacitance of the variable capacitor in response to the change in the frequency of the AC voltage supplied from the commercial power supply (50 Hz in the case of eastern Japan, 60 Hz in the case of west Japan). Is provided. By operating the switch, the frequency of the AC voltage output from the CR oscillation circuit is switched to 350 Hz or 360 Hz. Thus, when the frequency of the AC voltage supplied from the commercial power source is 50 Hz, the switch is controlled so that an AC voltage of 350 Hz is output from the CR oscillation circuit, and the frequency of the AC voltage supplied from the commercial power source is set. Is 60 Hz, the AC is output from the mixer circuit 401 b regardless of the frequency of the AC voltage supplied from the commercial power supply by controlling the switch so that an AC voltage of 360 Hz is output from the CR oscillation circuit. The frequency of the voltage is unified to 300 Hz.

  The signal conversion circuit 402 is configured to output a pulse signal corresponding to the frequency of the AC voltage to the modulation circuit 314 based on the input of the frequency-converted AC voltage. Specifically, the signal conversion circuit 402 includes two resistors 411 and 412 as amplitude adjustment means for adjusting the amplitude of the alternating voltage output from the frequency conversion circuit 401, and the alternating current adjusted by the amplitude adjustment means. A Schmitt trigger 413 (Schmitt inverter) is provided as conversion means for converting an AC voltage into a pulse signal based on a comparison between the voltage and a predetermined threshold voltage. The two resistors 411 and 412 are connected in series to the frequency conversion circuit 401. One end of the resistor 412 is grounded. Further, a Schmitt trigger 413 is disposed at a position in parallel with the resistor 412. The input terminal of the Schmitt trigger 413 is connected to the wiring connecting the two resistors 411 and 412, and the output terminal of the Schmitt trigger 413 is connected to the modulation circuit 314. With such a configuration, the AC voltage output from the frequency conversion circuit 401 is converted into a + 5V pulse signal.

  That is, the magnitude (amplitude) of the AC voltage applied to the Schmitt trigger 413 is determined by the ratio of the resistance values of the two resistors 411 and 412. Specifically, when the resistance values of the two resistors 411 and 412 are R1 and R2, respectively, and the amplitude of the AC voltage output from the frequency conversion circuit 401 is + 24V, the voltage applied to the Schmitt trigger 413 Is 24V × R2 / (R1 + R2). Therefore, for example, by setting the resistance value of R1 to 47 kΩ and the resistance value of R2 to 10 kΩ, the voltage applied to the Schmitt trigger 413 can be adjusted to + 5V.

  The Schmitt trigger 413 is electrically connected to the power supply and launch control board 321 via an electric path (not shown) and is supplied with power. The Schmitt trigger 413 outputs a LOW level signal if it is equal to or higher than a predetermined upper threshold voltage Vth, and outputs an HI level signal if it is lower than the predetermined lower threshold voltage Vtl. Specifically, when the AC voltage becomes equal to or higher than the upper limit threshold voltage Vth (for example, +4.3 V), the LOW level signal is subsequently output until the AC voltage becomes lower than the lower limit threshold voltage Vtl (for example, +3.5 V) lower than the upper limit threshold voltage Vth. When the AC voltage becomes lower than the lower limit threshold voltage Vtl, the HI level signal is output until the AC voltage becomes the upper limit threshold voltage Vth. Thereby, a pulse signal having a predetermined pulse width is obtained. The pulse signal is used as a hard random number clock signal.

  In addition, although the Schmitt trigger 413 used the inverter type thing, it is not restricted to this, You may use a buffer type thing.

  Next, the modulation circuit 314 will be described. The modulation circuit 314 is provided on a path connecting the hard random number clock circuit 313 and the MPU 311, and the hard random number clock signal output from the hard random number clock circuit 313 (specifically, output from the Schmitt trigger 413). Modulated pulse signal) to a pulse signal having two output intervals and two pulse widths.

  Specifically, the modulation circuit 314 includes a first D flip-flop 422, a second D flip-flop 423, a third D flip-flop 424, a first XOR circuit 425, and a second XOR circuit 426. Since each D flip-flop 422, 423, and 424 has the same configuration, the first D flip-flop 422 will be described as an example. The first D flip-flop 422 has a D1 terminal and a CLK1 terminal as input terminals, and an output. The Q1 terminal is provided as a terminal, and in synchronization with the signal input to the CLK1 terminal rising from the LOW level to the HI level, a signal corresponding to the signal state input to the D1 terminal at that time is supplied to the Q1 terminal. The output state is held until the next rise.

  Here, since each CLK terminal of each D flip-flop 422, 423, 424 is connected to the signal conversion circuit 402, the same signal is input to each CLK terminal. That is, the D flip-flops 422, 423, and 424 operate at the same timing. Hereinafter, the timing at which the D flip-flops 422, 423, and 424 are synchronized (the timing at which the signal input to the CLK terminal of the D flip-flop rises from the LOW level to the HI level) is referred to as the synchronization timing.

  Each of the XOR circuits 425 and 426 has two input terminals and one output terminal. When the signal states inputted to the two input terminals are the same, the XOR circuits 425 and 426 are LOW from the output terminal. While the level signal is output, if the signal states input to the two input terminals are different, the HI level signal is output from the output terminal.

  The output terminal of the first XOR circuit 425 is connected to the D1 terminal of the first D flip-flop 422, and one input terminal of the second XOR circuit 426 is connected to the Q1 terminal of the first D flip-flop 422. The output terminal of the second XOR circuit 426 is connected to the D2 terminal of the second D flip-flop 423, and the D3 terminal of the third D flip-flop 424 is connected to the Q2 terminal of the second D flip-flop 423. The Q3 terminal of the third D flip-flop 424 is connected to the MPU 311 and is also connected to the other input terminal of the first XOR circuit 425 and one input terminal of the second XOR circuit 426. The other input terminal of the first XOR circuit 425 is connected to the power source and the launch control board 321 via the power interruption monitoring board 302, and is supplied with + 5V voltage corresponding to the HI level signal.

  According to such a configuration, the output from the Q1 terminal changes according to the signal output from the Q3 terminal. Specifically, in the situation where the HI level signal is output from the Q3 terminal, the LOW level signal is output from the first XOR circuit 425 toward the D1 terminal. A LOW level signal is output from the terminal. On the other hand, in the situation where the LOW level signal is output from the Q3 terminal, the HI level signal is output from the first XOR circuit 425 toward the D1 terminal. A level signal is output.

  The output from the Q2 terminal changes according to the signals output from the Q1 terminal and the Q3 terminal. Specifically, in the situation where the signals output from the Q1 terminal and the Q3 terminal are the same, a LOW level signal is output from the second XOR circuit 426 to the D2 terminal. , A LOW level signal is output from the Q2 terminal. On the other hand, when the signals output from the Q1 terminal and the Q3 terminal are different, the HI level signal is output from the second XOR circuit 426 to the D2 terminal. An HI level signal is output.

  The output from the Q3 terminal changes according to the signal output from the Q2 terminal. Specifically, in the situation where the LOW level signal is output from the Q2 terminal, when the synchronization timing comes, the LOW level signal is output from the Q3 terminal, while the HI level signal is output from the Q2 terminal. When the synchronization timing is reached in the situation, the HI level signal is output from the Q3 terminal.

  Next, the operation of the modulation circuit 314 will be described with reference to the timing chart of FIG. The timing from t1 to timing t9 is the synchronization timing. That is, the hard random number clock signal output from the hard random number clock circuit 313 is input at these timings. Specifically, at these timings, the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level, and each of the D flip-flops 422, 423, and 424 is connected to the respective D terminals (D1) in synchronization with the rise. A signal corresponding to the signal input to the terminal, D2 terminal, D3 terminal) is output from each Q terminal (Q1, Q2, Q3 terminal). Note that, due to the characteristics of the D flip-flop, as shown in FIG. 22, when the signal state output from each Q terminal changes, the mode of the change (rise from LOW level to HI level or from HI level to LOW level). Is output with a slight delay with respect to the synchronization timing.

  At the timing t1, since the LOW level signal is output from the Q3 terminal, the HI level signal is output from the first XOR circuit 425. In this case, the output state from the Q1 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing of t1. At the timing t1, since the LOW level signal is output from both the Q1 terminal and the Q3 terminal, the LOW level signal is output from the second XOR circuit 426. In this case, a LOW level signal is output from the Q2 terminal. At the timing t1, the output state from the Q3 terminal is maintained at the LOW level.

  At the subsequent timing t2, since the LOW level signal is output from the Q3 terminal, the HI level signal is output from the first XOR circuit 425. In this case, the HI level signal is output from the Q1 terminal. Since the HI level signal is output from the Q1 terminal and the LOW level signal is output from the Q3 terminal, the HI level signal is output from the second XOR circuit 426. In this case, the output state from the Q2 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing of t2. At the timing t2, the output state from the Q3 terminal is maintained at the LOW level.

  At the timing of t3, since the LOW level signal is output from the Q3 terminal, the HI level signal is output from the first XOR circuit 425. In this case, the HI level signal is output from the Q1 terminal. At the timing of t3, the HI level signal is output from the Q1 terminal, while the LOW level signal is output from the Q3 terminal, the HI level signal is output from the second XOR circuit 426. In this case, the HI level signal is output from the Q2 terminal. Furthermore, at the timing of t3, the HI level signal is output from the Q2 terminal. In this case, the output state from the Q3 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing of t3. The counter circuit 317 is synchronized with the rise, and the big hit random number counter C1 is updated.

  At the timing t4, since the HI level signal is output from the Q3 terminal, the LOW level signal is output from the first XOR circuit 425. In this case, the output state from the Q1 terminal falls from the HI level to the LOW level at a timing slightly delayed from the timing of t4. At the timing t4, since the HI level signal is output from both the Q1 terminal and the Q3 terminal, the LOW level signal is output from the second XOR circuit 426. In this case, the output state from the Q2 terminal falls from the HI level to the LOW level at a timing slightly delayed from the timing of t4. At the timing t4, the output state from the Q3 terminal is maintained at the HI level.

  At the timing of t5, since the HI level signal is output from the Q3 terminal, the LOW level signal is output from the first XOR circuit 425. In this case, a LOW level signal is output from the Q1 terminal. At the timing t5, the LOW level signal is output from the Q1 terminal, while the HI level signal is output from the Q3 terminal, the HI level signal is output from the second XOR circuit 426. In this case, the output state from the Q2 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing t5. Furthermore, since the LOW level signal is output from the Q2 terminal at the timing t5, the output state from the Q3 terminal falls from the HI level to the LOW level at a timing slightly delayed from the timing t5.

  At the timing t6, since the LOW level signal is output from the Q3 terminal, the HI level signal is output from the first XOR circuit 425. In this case, the output state from the Q1 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing of t6. At the timing t6, since the LOW level signal is output from both the Q1 terminal and the Q3 terminal, the LOW level signal is output from the second XOR circuit 426. In this case, the output state from the Q2 terminal falls from the HI level to the LOW level at a timing slightly delayed from the timing of t6. Further, since the HI level signal is output from the Q2 terminal at the timing t6, the output state from the Q3 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing t6. The big hit random number counter C1 is updated in synchronization with the rise of the counter circuit 317.

  Here, the period Ta from the timing t3 to the timing t6 (specifically, the period from the timing slightly delayed from the timing t3 to the timing slightly delayed from the timing t6) is the update interval of the big hit random number counter C1. ing. The period Ta is three times the period T1 of the pulse signal output from the Schmitt trigger 413 (the period T1 of the hard random number clock signal output from the hard random number clock circuit 313). That is, the update interval (period Ta) of the jackpot random number counter C1 and the cycle T1 of the pulse signal output from the signal conversion circuit 402 are different. Thereby, even when the period T1 of the pulse signal output from the Schmitt trigger 413 is grasped, the update timing of the big hit random number counter C1 is hardly grasped.

  At the timing of t7, since the HI level signal is output from the Q3 terminal, the LOW level signal is output from the first XOR circuit 425. In this case, the output state from the Q1 terminal falls from the HI level to the LOW level at a timing slightly delayed from the timing of t7. At the timing t7, since the HI level signal is output from both the Q1 terminal and the Q3 terminal, the LOW level signal is output from the second XOR circuit 426, and therefore, the LOW level signal is output from the Q2 terminal. At the timing of t7, the output state from the Q3 terminal is maintained at the LOW level.

  At the timing of t8, since the output states of the Q1, Q2 and Q3 terminals are the same as in the case of the timing of t1, the Q1 terminal is slightly delayed from the timing of t8 as in the case of the timing of t1. The output state from Q rises from the LOW level to the HI level, while the outputs from the Q2 terminal and the Q3 terminal are maintained at the LOW level. In this case, the period T2 from the timing t1 to the timing t8 is one cycle, and the operations from the timing t1 to the timing t8 are repeatedly executed. That is, a pulse signal group including two pulse signals having different pulse widths is repeatedly output at the period T2. The pulse signal group is input to the MPU 311 as a hard random number clock signal.

  Thereafter, the signal output from the Q3 terminal rises from the LOW level to the HI level at a timing slightly delayed from the timing t9, and the jackpot random number counter C1 is updated at the timing. That is, the period Tb from the timing t6 to the timing t9 is an update interval of the big hit random number counter C1. In other words, since the pulse signal is alternately output from the Q3 terminal at two types of rising edge intervals, the update interval of the big hit random number counter C1 also changes alternately. In other words, based on the input of the pulse signal from the signal conversion circuit 402, the modulation circuit 314 has a rising interval different from the cycle T1 of the input pulse signal, and alternately pulses at two types of rising intervals. It can be said that it outputs a signal. Then, the update of the jackpot random number counter C1 corresponding to the pulse signal group is repeated for each pulse signal group. As a result, there are two types of update intervals at which the jackpot random number counter C1 is updated, and therefore, it is difficult to grasp the update interval of the jackpot random number counter C1.

  If attention is paid to the fact that the jackpot random number counter C1 is updated in synchronization with the rising edge of the pulse signal, the rising edge of the pulse signal can be regarded as a trigger. In this case, the modulation circuit 314 modulates the pulse signal input from the signal conversion circuit 402 and outputs a pulse signal group including a plurality of pulse signals as one cycle, thereby triggering the update of the jackpot random number counter C1. There are two types of trigger intervals, and it can be said that the two types of trigger intervals are set to be different from the cycle T1 of the input pulse signal.

  In practice, the delay period from the synchronization timing until the output state from each Q terminal changes is sufficiently small with respect to the cycle T1 of the hard random number clock signal. The timing when the output state changes is assumed to be the same timing.

  Next, the relationship between the update interval of the jackpot random number counter C1 and the numerical range of the jackpot random number counter C1 will be described with reference to FIG. Here, in the update interval of the jackpot random number counter C1, one period Ta is simply referred to as Ta, and the other period Tb is simply referred to as Tb. Among the pulse signal group, the pulse signal output earlier (the one with the larger pulse width). The rising timing of the first pulse signal) is referred to as a first timing, and the rising timing of a pulse signal (pulse signal having a smaller pulse width) output later is referred to as a second timing. FIG. 23A is a timing chart showing how the jackpot random number counter C1 is updated when the jackpot random number counter C1 becomes “0” at the first timing, and FIG. 23B shows the second timing. 5 is a timing chart showing how the jackpot random number counter C1 is updated when the jackpot random number counter C1 becomes “0”.

  Further, for convenience of explanation, the explanation will be made assuming that the numerical range of the jackpot random number counter C1 is “0 to 4” and the winning value is “2”. Note that the number of terms in the sequence composed of numerical values that can be taken by the jackpot random number counter C1 is referred to as a counter term number. For example, when the numerical range of the jackpot random number counter C1 is “0 to 4”, the numerical sequence composed of values that the jackpot random number counter C1 can take is “0, 1, 2, 3, 4”, and the counter term The number is “5”. If extended to a general formula, if the numerical range of the jackpot random number counter C1 is “0 to N”, the number of counter terms is “N + 1”.

  As shown in FIG. 23A, when the jackpot random number counter C1 becomes “0” at the first timing, the period required for the jackpot random number counter C1 to make one round is 3Ta + 2Tb, The period during which the winning value is “2” is Ta. That is, the jackpot random number counter C1 holds a value of “2” only for Ta in the period of 3Ta + 2Tb, and if the value of the jackpot random number counter C1 is acquired during the period, the jackpot win is won. In other words, from the viewpoint of the period, the jackpot winning probability is Ta / (3Ta + 2Tb).

  When the jackpot random number counter C1 becomes “0” at the first timing, the timing when the jackpot random number counter C1 becomes “4” is the first timing. Then, the big hit random number counter C1 becomes “0” at the second timing, and the update is performed sequentially. In this case, the period required until the jackpot random number counter C1 makes one round is 2Ta + 3Tb as shown in FIG. 23B, and the period that was the value of “2” as the winning value within the period is Tb. Therefore, the jackpot winning probability in this case is Tb / (2Ta + 3Tb).

  That is, the period in which the value of the jackpot random number counter C1 is the winning value varies depending on whether the jackpot random number counter C1 is updated from “0” at the first timing or the second timing. At the same time, the period for which the jackpot random number counter C1 makes one round also varies. In other words, among the pulse signals included in the pulse signal group, the value of the jackpot random number counter C1 becomes the winning value by the fluctuation of the pulse signal corresponding to the update in which the value of the jackpot random number counter C1 becomes the initial value. Period and the period in which the jackpot random number counter C1 makes one revolution. Thus, every time the jackpot random number counter C1 makes one turn, the period in which the value of the jackpot random number counter C1 is the winning value, the period until the value of the jackpot random number counter C1 becomes the winning value from the initial value, and the jackpot random number The period until the counter C1 makes one revolution varies. Therefore, it is more difficult to grasp the timing at which the value of the jackpot random number counter C1 is the winning value.

  For example, when the period until the jackpot random number counter C1 makes one round is known, there is a possibility that the update interval of the jackpot random number counter C1 is grasped. In such a situation, when the winning value is grasped, there is a possibility that the timing at which the value of the jackpot random number counter C1 becomes the winning value may be specified. On the other hand, in this embodiment, the trigger interval of the hard random number clock signal that triggers the update of the jackpot random number counter C1 is set to two types, and the number of counter terms of the jackpot random number counter C1 is an odd number. By setting the numerical range of the jackpot random number counter C1, the timing at which the jackpot random number counter C1 becomes “0” is alternately switched between the first timing and the second timing. As a result, the period in which the value of the jackpot random number counter C1 is the winning value and the period required for the jackpot random number counter C1 to make one round change, so the timing at which the value of the jackpot random number counter C1 becomes the winning value can be grasped. It is difficult. Therefore, by specifying the period in which the jackpot random number counter C1 makes one round, it is possible to suppress an illegal act of grasping the timing when the value of the jackpot random number counter C1 becomes the winning value.

  In this case, a random number initial value counter is separately provided, and the updating process of the counter is performed separately from the update of the big hit random number counter C1, and when the big hit random number counter C1 makes one round, the value of the random number initial value counter at that time is A configuration in which the initial value of the jackpot random number counter C1 is read is also conceivable. However, in this configuration, it is necessary to separately provide a random number initial value counter in the counter area of the RAM 316 and perform update processing of the random number initial value counter and initial value setting processing of the jackpot random number counter C1. Then, there is a concern about increase in capacity, complexity of configuration, and increase in processing load caused by providing the random number initial value counter.

  On the other hand, according to the present embodiment, it is possible to vary the timing at which the value of the big hit random number counter C1 becomes the winning value without imposing a processing load on the MPU 311. Furthermore, since the update of the jackpot random number counter C1 is executed independently of various software processes executed by the MPU 311, it is possible to suppress an illegal act on the software process such as rewriting a program.

  Further, considering the substantial winning probability, the substantial winning probability is the average of the jackpot winning probability when the update is started from the timings of the first timing and the second timing, so (Tb / (2Ta + 3Tb ) + Ta / (3Ta + 2Tb)) / 2. In this case, when Ta = 3T1 and Tb = 4T1 are substituted, the substantial winning probability is 19.93%, which is substantially the same as the theoretical probability 20.00% calculated from the value of the jackpot random number counter C1. That is, every time the jackpot random number counter C1 makes a round, the jackpot winning probability fluctuates, but the overall winning probability is substantially the same as the theoretical probability. Therefore, the fairness of the game and the management of the game in the game hall are easy. Sex is guaranteed.

  Specifically, if the range of values that the jackpot random number counter C1 can take is “0 to 5”, the number of counter terms is an even number. Therefore, the timing at which the jackpot random number counter C1 becomes “0” is the first timing. Alternatively, it is fixed at one of the second timings. Further, if the winning timing is fixed at the first timing, the substantial winning probability is calculated as 17.65% from Ta / (3Ta + 2Tb). On the other hand, if the timing at which the jackpot random number counter C1 is “0” is always the second timing, the substantial winning probability is calculated from Tb / (2Ta + 3Tb) to 22.22%.

  Thus, the substantial jackpot winning probability varies depending on whether the timing at which the jackpot random number counter C1 becomes “0” is fixed at the first timing or the second timing. For this reason, the fairness of the game cannot be maintained, and management of the game in the game hall becomes difficult.

  On the other hand, when the numerical range of the jackpot random number counter C1 is “0 to 4”, the number of counter terms becomes an odd number, and the jackpot random number counter C1 becomes “0” every time the jackpot random number counter C1 makes one round. The timing varies between the first timing and the second timing. As a result, the substantial winning probability is the average of the winning probability at the first timing and the winning probability at the second timing, and thus the inconvenience is avoided.

  As the difference between Ta and Tb increases, the difference between the actual winning probability and the theoretical probability increases. On the other hand, the fluctuation that occurs each time the jackpot random number counter C1 makes one round increases. Focusing on the viewpoint, the difference between Ta and Tb may be increased.

  Further, if attention is paid to the fact that the jackpot random number counter C1 goes around a plurality of times, the period in which the jackpot random number counter C1 is the winning value is repeated with “Ta, Tb” as a unit period, and the jackpot random number counter C1 It can be said that the period required for one round is repeated with “2Ta + 3Tb, 3Ta + 2Tb” as a unit period.

  Here, for convenience of explanation, the numerical value range that can be taken by the jackpot random number counter C1 is set to “0 to 4”, and the value “2” is assumed to be a winning value. “0 to 676” may be set. In this case, a plurality of winning values may be set so as to obtain a desired jackpot winning probability. In short, the numerical range of the jackpot random number counter C1 may be set so that the number of counter terms is an odd number.

  Further, if there are three pulse signals included in the pulse signal group output from the modulation circuit 314, the numerical range of the big hit random number counter C1 may be set so that the counter term number is not a multiple of three. . As a result, the pulse signal corresponding to the update in which the value of the jackpot random number counter C1 becomes the initial value in the pulse signal group varies.

  In other words, the numerical range of the jackpot random number counter C1 and the modulation circuit 314 may be configured so that the number of counter terms does not become a multiple of the number of pulse signals included in the pulse signal group output from the modulation circuit 314. If it explains using a numerical formula, if the number of signals of the pulse signal included in the pulse signal group is “m” and the possible range of the jackpot random number counter C1 is “0 to N”, N + 1 ≠ K × m (K: The numerical value range “0 to N” of the jackpot random number counter C1 and the signal number “m” of the pulse signals included in the pulse signal group may be set so as to satisfy the relationship of (natural number).

  In particular, if N + 1 = K × m ± 1 (K: natural number), every time the big hit random number counter C1 makes one round, a pulse corresponding to an update in which the value of the big hit random number counter C1 becomes the initial value in the pulse signal group. The signal is shifted by 1. Then, all the pulse signals included in the pulse signal group can be triggered when the value of the jackpot random number counter C1 is updated to the initial value.

  In this case, if the jackpot winning probabilities corresponding to the respective pulse signals included in the pulse signal group are P1, P2,..., Pm, the substantial winning probabilities are averaged by (P1 + P2 +... + Pm) / m. Thus, every time the jackpot random number counter C1 makes one round, a period from a timing at which the value of the jackpot random number counter C1 becomes an initial value to a timing at which it becomes a winning value, a period during which the value of the jackpot random number counter C1 is a winning value, While the period required for the jackpot random number counter C1 to make one round and the jackpot winning probability vary, the substantial winning probability does not vary. Therefore, the fairness of the game can be ensured while changing the timing at which the value of the jackpot random number counter C1 becomes the winning value.

  Next, acquisition of the jackpot random number counter C1 will be described with reference to the flowchart of FIG.

  First, in step S304, processing for prohibiting the update of the big hit random number counter C1 is executed. Specifically, a process of blocking the input of the hard random number clock signal to the MPU 311 is executed. Although not shown in detail, a MOSFET is provided as a switching element that permits or blocks input of a hard random number clock signal to the MPU 311, and the MOSFET is supplied to the MPU 311 in accordance with a signal from the MPU 311. The hard random number clock signal is input or blocked.

  In subsequent step S305, processing for obtaining the value of the jackpot random number counter C1 at that time is executed, and then in step S306, update prohibition release processing is executed. Specifically, the input of the hard random number clock signal to the MPU 311 is resumed. Thereby, the update of the jackpot random number counter C1 is resumed.

  Here, since the update of the big hit random number counter C1 and the timer interruption process are independently performed in parallel, the big hit random number counter C1 is updated in the situation where the acquisition process of the big hit random number counter C1 is performed. May be. In this case, the consistency of the value of the jackpot random number counter C1 may be lost, or acquisition of the value of the jackpot random number counter C1 may fail. In particular, the hard random number clock signal used as the reference clock signal in the update of the jackpot random number counter C1 and the system clock signal used as the reference clock signal in the operation of the MPU 311 for executing the timer interrupt process are not synchronized with each other. Since it is set, the above inconvenience is likely to occur.

  On the other hand, in this embodiment, since the input of the hard random number clock signal to the MPU 311 is interrupted during the process of acquiring the big hit random number counter C1, the big hit random number counter during this period. C1 is not updated. Thereby, the said inconvenience can be avoided.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In addition to the system clock circuit 312 that outputs the system clock signal, a hard random number clock circuit 313 that outputs a hard random number clock signal that triggers the update of the jackpot random number counter C1 is provided. The hard random number clock signal and the system clock signal were set to have different periods. Thereby, even if the period of the system clock signal is specified, the update interval of the big hit random number counter C1 is difficult to be specified. Therefore, by grasping the update timing of the jackpot random number counter C1, an illegal signal can be output at the timing when the value of the jackpot random number counter C1 becomes the winning value, and the act of generating the jackpot illegally can be suppressed.

  Since the hard random number clock signal and the system clock signal are not synchronized with each other, the timing at which the value of the jackpot random number counter C1 becomes the winning value is specified in synchronization with the input of the system clock signal. Cheating can be suppressed.

  A signal conversion circuit 402 that converts an alternating voltage into a pulse signal is provided. Thereby, since a pulse signal is obtained using a commercial power source, the configuration can be simplified.

  Here, since the frequency of the AC voltage from the commercial power supply is known (50 Hz or 60 Hz), the cycle of the pulse signal is specified from the frequency, and the update timing of the jackpot random number counter C1 may be specified from the cycle. is there.

  On the other hand, according to the present embodiment, the frequency conversion circuit 401 that converts the frequency of the AC voltage into a specific frequency is provided. Thereby, since it is difficult to specify the frequency of the alternating voltage input to the signal conversion circuit 402, it is difficult to specify the update interval of the jackpot random number counter C1.

  Further, the hard random number clock circuit 313 outputs the hard random number clock signal cycle T1 and the hard random number counter C1 to update the pulse signal trigger interval (Ta or Tb) that triggers the update. A modulation circuit 314 for modulating the clock signal is provided. Thereby, even if the period T1 of the pulse signal is grasped, it is difficult to grasp the update timing of the big hit random number counter C1. Therefore, by grasping the period T1 of the pulse signal, it is possible to suppress an illegal act of specifying the update timing of the jackpot random number counter C1.

  The modulation circuit 314 outputs a pulse signal group including a plurality of pulse signals as one cycle, and the update of the jackpot random number counter C1 corresponding to the pulse signal group is repeated for each pulse signal group. Here, the numerical range of the jackpot random number counter C1 and the number of signals of the pulse signal are set so that the number of counter terms is not a multiple of the number of signals of the pulse signal included in the pulse signal group. As a result, the timing at which the value of the jackpot random number counter C1 becomes the winning value changes every time the jackpot random number counter C1 makes one round, and therefore it is difficult to specify the timing at which the value of the jackpot random number counter C1 becomes the winning value. Can do.

  In addition, by changing the update interval, the period required for the jackpot random number counter C1 to make one round sequentially changes to one of two types of periods, while the unit period including these two types of periods However, the jackpot random number counter C1 is repeated every two rounds. Thus, a unit period (a period required for the big hit random number counter C1 to make one round when started from the first timing and a period required for the big hit random number counter C1 to make one round when started from the second timing) The winning probability is constant during the combined period. Therefore, since the actual winning probability does not change, the fairness of the game and the ease of management of the game hall are ensured.

  Further, every time the jackpot random number counter C1 makes one turn, the period in which the jackpot random number counter C1 is the winning value is sequentially shifted to any one of the two types of periods (Ta or Tb). The period occupying the unit period is constant (Ta + Tb). Thus, if the unit period is focused on as one unit, the winning probability is constant. Therefore, since the actual winning probability does not change, the fairness of the game and the ease of management of the game hall are ensured.

  If attention is paid to the fact that the jackpot random number counter C1 makes a plurality of rounds, the period in which the jackpot random number counter C1 is a winning value and the period required for the jackpot random number counter C1 to make one round are units having a plurality of types of periods. It can be said that the period is configured to sequentially shift to any of a plurality of types of periods included in the unit period, and the winning probability may be substantially constant for each unit period.

<Second Embodiment>
In the first embodiment, when the jackpot random number counter C1 makes one round, the jackpot random number counter C1 is configured to return to a predetermined value (“0”). On the other hand, in the present embodiment, the processing when the big hit random number counter C1 makes one round is different from the first embodiment. The difference will be described. In addition, about the same structure as 1st Embodiment, while attaching | subjecting the same code | symbol, description is abbreviate | omitted.

  In this embodiment, random number initial value counters CINI are provided in various counter areas of the RAM 316. The numerical value range that the random number initial value counter CINI can correspond to the jackpot random number counter C1 is determined. For example, when the numerical range that the jackpot random number counter C1 can take is “0 to 4”, The initial value counter CINI is also set to “0 to 4”.

  Next, timer interrupt processing in this embodiment will be described with reference to the flowchart of FIG.

  First, in step S601, a signal reading process is executed. In the signal reading process, information input to the input port 311a from the ball detection sensors provided individually for the general winning port 82, the variable winning device 83, the operating port 84 and the through gate 85 is confirmed, and the confirmation result To determine whether or not there is a ball entering each ball club. Specifically, input of a signal (for example, a LOW level signal) corresponding to not detecting a game ball in any one process is confirmed, and a game ball is detected in the subsequent two processes. When the input of a signal (for example, an HI level signal) corresponding to being performed is continuously confirmed, it is specified that a game ball has entered in the entrance corresponding to the detection sensor.

  After executing the signal reading process, the random number initial value counter CINI is updated in step S602. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 (initialized) when the value reaches the maximum value.

  Thereafter, update prohibition processing is executed in step S603. In this process, a process for prohibiting the update of the jackpot random number counter C1 is executed. Specifically, the input of the hard random number clock signal to the MPU 311 is blocked.

  In a succeeding step S604, a process of acquiring the value of the big hit random number counter C1 is executed, and the process proceeds to a step S605.

  In step S605, based on the value of the jackpot random number counter C1 acquired in step S604, processing for determining whether or not the jackpot random number counter C1 has made one round is executed. Specifically, it is determined whether or not the acquired value of the jackpot random number counter C1 matches the initial value set when the previous jackpot random number counter C1 makes one round. If it is determined that the jackpot random number counter C1 has not made one round, the process proceeds to step S607, whereas if it is determined that the jackpot random number counter C1 has made one round, the process proceeds to step S606 to perform initial value setting processing. Execute. Specifically, the process reads out the value of the random number initial value counter CINI at that time and writes the value as the initial value of the jackpot random number counter C1.

  The random number initial value counter CINI is a counter that is updated by the timer interrupt process, and varies according to the read timing. As a result, the initial value of the jackpot random number counter C1 varies. Therefore, even if the number of counter terms is a multiple of the number of signals of the clock signal included in the clock signal group, the value of the big hit random number counter C1 becomes the initial value every time the big hit random number counter C1 makes one round. The period from the start timing to the winning timing, the period in which the value of the jackpot random number counter C1 is the winning value, and the jackpot winning probability fluctuate, but the substantial winning probability does not change.

  Here, the update interval of the jackpot random number counter C1 is set to be longer than 2 msec, which is a period required for one processing of the timer interrupt process. Specifically, since the frequency of the AC voltage output from the frequency conversion circuit 401 is 300 Hz, the cycle of the pulse signal output from the signal conversion circuit 402 is 1/300 sec. Since the modulation interval is modulated by the modulation circuit 314 so that the trigger interval is Ta = 3T1 or Tb = 4T1, the update interval of the big hit random number counter C1 is 10 msec or about 13 msec. As a result, the timer interruption process is executed at least once after the big hit random number counter C1 is updated until the next big hit random number counter C1 is updated. Therefore, it is possible to reliably specify that the big hit random number counter C1 makes one round in the timer interrupt process.

  After the process of step S606 is completed, the process proceeds to step S607, and the update prohibition release process is executed. In the update prohibition release process, the input of the hard random number clock signal to the MPU 311 is resumed. Thereby, the update of the jackpot random number counter C1 is resumed.

  That is, the update of the jackpot random number counter C1 is prohibited during the period from the acquisition process of the jackpot random number counter C1 to the initial value setting process. As a result, during the timer interrupt process, updating of the jackpot random number counter C1 is prohibited while the MPU 311 is accessing the jackpot random number counter C1. Therefore, an error that may occur due to different processing being simultaneously performed on the big hit random number counter C1 is avoided.

  Thereafter, in step S609, a start winning process is executed. Since this process is the same as the process shown in FIG.

  According to the embodiment described in detail above, when the random number initial value counter CINI is provided and the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is set as the initial value of the jackpot random number counter C1. Execute the setting process. As a result, even if the number of counter terms is a multiple of the number of pulse signals included in the pulse signal group, the value of the big hit random number counter C1 becomes the initial value every time the big hit random number counter C1 makes one round. The period from the time when the value is reached to the timing when the winning value is reached, the period when the value of the jackpot random number counter C1 is the winning value, and the jackpot winning probability vary, but the substantial winning probability does not vary. Therefore, it is difficult to specify the timing at which the value of the jackpot random number counter C1 becomes the winning value. Therefore, by specifying the timing at which the value of the jackpot random number counter C1 becomes the winning value and outputting an incorrect signal at the timing, the numerical range of the jackpot random number counter C1 is suppressed while intentionally generating the jackpot. In addition, the degree of freedom of the number of signals of the pulse signal group can be increased.

  In such a configuration, in order to grasp the value of the jackpot random number counter C1, it is necessary to grasp the update timing of the jackpot random number counter C1 and the update timing of the random number initial value counter CINI. Here, the random number initial value counter CINI is updated by software processing by the MPU 311, while the big hit random number counter C1 is independently updated based on the hard random number clock signal. Thereby, the update timing of the random number initial value counter CINI and the update timing of the jackpot random number counter C1 are different from each other. Therefore, since it is necessary to grasp both timings, it is difficult to specify the value of the big hit random number counter C1. Therefore, it is possible to make it difficult to specify the timing at which the value of the jackpot random number counter C1 becomes the winning value.

  Further, the update process of the big hit random number counter C1 is prohibited before and after the process so that the big hit random number counter C1 is not updated during the process of setting the initial value. As a result, in the situation where the MPU 311 is accessing the jackpot random number counter C1, it is possible to prevent the occurrence of errors that may be caused by updating the jackpot random number counter C1.

<Third Embodiment>
In the first embodiment, the jackpot random number counter C1 is updated based on the input of the hard random number clock signal output from the hard random number clock circuit 313, and the hard random number clock signal is Modulation was performed so that the signals were alternately output at two output intervals of Ta and Tb. And the difference of Ta and Tb was set small so that a substantial probability might approach the theoretical probability. On the other hand, in this embodiment, the big hit random number counter C1 is updated using a hard random number clock signal having a large difference between Ta and Tb. Hereinafter, the difference will be described. For convenience of explanation, it is assumed that the numerical value range that the jackpot random number counter C1 can take is set to “0 to 1”, and the winning value is set to “0”.

  As shown in the timing chart of FIG. 25, the output interval of the hard random number clock signal output from the modulation circuit 314 is set so that Tb is five times that of Ta. Then, if the rising timing of the previous pulse signal (pulse signal with the smaller pulse width) is the first timing and the rising timing of the subsequent pulse signal (pulse signal with the larger pulse width) is the second timing, The big hit random number counter C1 is set to “0” at the timing, and the big hit random number counter C1 is set to “1” at the second timing.

  In such a configuration, the period until the jackpot random number counter C1 makes one turn is 6Ta, and the period in which the winning value is “0” in the period is Ta, so the substantial winning probability is 1 / 6. The probability is smaller than the theoretical probability 1/2 calculated from the numerical range that the jackpot random number counter C1 can take. That is, the substantial winning probability is adjusted by adjusting the difference between Ta and Tb.

  According to the embodiment described above in detail, the modulation circuit 314 that modulates the pulse signal is provided so that the hard random number clock signal is output at two kinds of intervals. Thereby, the substantial winning probability can be adjusted by adjusting the difference between the two intervals. Therefore, the update frequency of the jackpot random number counter C1 can be reduced while setting the jackpot winning probability to a predetermined probability. Therefore, the processing load can be reduced.

  In particular, when there are two types of output intervals of the hard random number clock signal, by increasing the difference between them, the substantial winning probability is made lower than the theoretical probability calculated from the numerical range that the jackpot random number counter C1 can take. can do. As a result, the counter value required for setting the predetermined winning probability can be reduced, so that the capacity required for the jackpot random number counter C1 can be reduced.

  In this case, since the period in which the value of the jackpot random number counter C1 is the winning value is shorter than the period in which the other numbers are set, the value of the jackpot random number counter C1 is the winning value. It has become difficult to match the period. As a result, an illegal signal can be output in synchronization with the timing when the value of the jackpot random number counter C1 is the winning value, and an illegal act that intentionally generates a jackpot can be suppressed.

  In this embodiment, the output interval of the hard random number clock signal is set to two types. However, the output interval is not limited to this, and may be, for example, three types or four types.

<Fourth Embodiment>
In each of the above embodiments, the hard random number clock circuit 313 is configured to generate the hard random number clock signal by converting the alternating voltage supplied from the alternating current power supply unit 321d. On the other hand, in the present embodiment, the configuration relating to the hard random number clock circuit 313 is different from that in each of the above embodiments, and the difference will be described with reference to FIG. FIG. 26 is a block diagram showing a part of the electrical configuration of the pachinko machine 10 in the present embodiment. In addition, about the same structure as 1st Embodiment, while attaching | subjecting the same code | symbol, description is abbreviate | omitted.

  In the present embodiment, as shown in FIG. 26, a signal line LN1 and a signal line LN2 are provided as signal paths connecting the system clock circuit 312 and the MPU 311. The system clock circuit 312 outputs a system clock signal to the MPU 311 via both the signal line LN1 and the signal line LN2.

  Here, a clock conversion circuit 501 is provided on the signal line LN2. The clock conversion circuit 501 converts the system clock signal input from the system clock circuit 312 into a hard random number clock signal and outputs the hard random number clock signal to the MPU 311.

  Specifically, the clock conversion circuit 501 includes a frequency dividing circuit 502 that divides the frequency of the input clock signal, and a phase shift circuit 503 that shifts the phase of the clock signal by a predetermined amount.

  The frequency dividing circuit 502 is connected to the system clock circuit 312 via the signal line LN2, and divides the frequency of the system clock signal output from the system clock circuit 312 into 1 / N (N: natural number). In addition, the divided clock signal is output to the phase shift circuit 503. The period of the divided clock signal is different from the period of the system clock signal. The frequency of the divided clock signal corresponds to the specific frequency in the first embodiment.

  The phase shift circuit 503 shifts the phase of the divided clock signal output from the frequency dividing circuit 502 by a predetermined amount, and outputs the shifted clock signal to the MPU 311 as a hard random number clock signal. As a result, when the hard random number clock signal and the system clock signal are compared, the periods are different from each other and the phases are different from each other. Therefore, the hard random number clock signal and the system clock signal are not synchronized.

  A modulation circuit 314 is provided on the signal line LN2 that connects the clock conversion circuit 501 and the MPU 311. The modulation circuit 314 modulates the hard random number clock signal output from the clock conversion circuit 501 and outputs a pulse signal group including a plurality of pulse signals as one cycle, thereby triggering the update of the big hit random number counter C1. The trigger has two kinds of intervals. As a result, the update interval of the jackpot random number counter C1 varies.

  According to the embodiment described above in detail, the clock conversion circuit 501 is provided that generates the hard random number clock signal having a period and phase different from that of the system clock signal by changing the system clock signal. Accordingly, it is not necessary to provide a circuit (hard random number clock circuit 313 and AC power supply unit 321d in the first embodiment) that independently outputs a hard random number clock signal, so that the configuration can be simplified.

  Even in this case, by providing the modulation circuit 314 on the signal line LN2 connecting the clock conversion circuit 501 and the MPU 311, the update interval of the big hit random number counter C1 can be changed.

  The frequency of the hard random number clock signal can be set so that the trigger interval is longer than the period of the timer interrupt process by adjusting the frequency dividing ratio of the frequency dividing circuit 502. Thereby, it is determined whether or not the configuration of the second embodiment, specifically, the jackpot random number counter C1 makes one round, and if it is determined that the jackpot random number counter C1 makes one round, the jackpot A configuration for executing an initial value setting process of the random number counter C1 can be applied.

<Fifth Embodiment>
In the present embodiment, the configuration relating to the update of the jackpot random number counter C1 is different from the above embodiments. The difference will be described. In addition, about the same structure as said each embodiment, while attaching | subjecting the same code | symbol, description is abbreviate | omitted.

  In this embodiment, as shown in FIGS. 27 and 28, the hard random number clock circuit 313 is not provided, and a big hit random number counter C1 is provided in the counter area of the RAM 316 instead of the counter circuit 317. This is different from the above embodiments. The jackpot random number counter C1 is configured to be updated by the MPU 311 similarly to the other counters (the jackpot type counter C2 and the reach random number counter C3).

  In addition, a random number initial value counter CINI is provided in the counter area, and the random number initial value counter CINI is also updated in the control related to the progress of the game in the MPU 311.

  The main control board 301 is provided with a reset circuit 601 and an irregular delay circuit 602. The reset circuit 601 is electrically connected to the MPU 311 via the irregular delay circuit 602. The reset circuit 601 switches the output state of the signal directed to the MPU 311 to the HI level or the LOW level according to the voltage supplied from the power interruption monitoring board 302. Specifically, in a situation where an external power source is supplied to the power source and launch control board 321, the HI level for operating the MPU 311 when the voltage of the power source supplied from the power source and launch control board 321 is equal to or higher than the reference voltage. A signal is output, and a LOW level is output in order to stop the operation of the MPU 311 in a situation where the voltage is lower than the reference voltage (that is, a situation where the pachinko machine 10 is in a power interruption state). The HI level signal corresponds to a reset signal as an operation signal. The MPU 311 performs a process of updating the jackpot random number counter C1 based on the input of the reset signal. Here, a state in which external power is supplied to the power supply and launch control board 321 is referred to as a power-on state of the pachinko machine 10, and a state in which no external power is supplied is referred to as a power-off state of the pachinko machine 10. That is, the power-on state refers to a state in which operating power is supplied to the pachinko machine 10, and the power interruption state refers to a state in which operating power is not supplied to the pachinko machine 10.

  The irregular delay circuit 602 varies the input timing of the reset signal to the MPU 311 with respect to the output timing of the reset signal output from the reset circuit 601. This will be described later.

<Timer interrupt processing>
FIG. 29 is a flowchart showing timer interrupt processing in the present embodiment.

  In the timer interrupt process, first, in step S701, a signal reading process is executed. In the signal reading process, information input to the input port 311a from the ball detection sensors provided individually for the general winning port 82, the variable winning device 83, the operating port 84 and the through gate 85 is confirmed, and the confirmation result To determine whether or not there is a ball entering each ball club.

  After executing the signal reading process, the random number initial value counter CINI is updated in step S702. In subsequent step S703, the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3 are updated. Such an update corresponds to an update by the numerical information update means. Specifically, the value of each random number counter is incremented by 1 and it is determined whether or not the added value is an upper limit value. If the added value exceeds the upper limit value, the counter value is set to the initial value. Here, with respect to the jackpot random number counter C1, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. Since the random number initial value counter CINI is a random value, the initial value of the jackpot random number counter C1 varies. Therefore, the timing at which the value of the jackpot random number counter C1 coincides with the winning value is different every time the jackpot random number counter C1 makes a round, so it is difficult to grasp the timing at which the value of the jackpot random number counter C1 becomes the winning value. It has become.

  Thereafter, a start winning process is executed in step S704. Specifically, as shown in the flowchart of FIG. 30, the presence or absence of winning of the operation port 84 is confirmed in S801, and it is determined whether or not the number N of operation pending balls is smaller than 4 in Step S802. In step S803, N is incremented by one. Then, in step S804, various counters C1, C2, C3 are stored in the reserved ball storage area corresponding to the number N of active reserved balls.

  Here, in this embodiment, since the jackpot random number counter C1 is updated by the MPU 311, in the start winning process, when the jackpot random number counter C1 is acquired, the update of the jackpot random number counter C1 is prohibited (see FIG. Steps S304 to S306 in FIG. 18 are omitted.

<Regarding Irregular Delay Circuit 602>
As described above, in the pachinko machine 10, when a game ball enters the operation port 84, a big hit lottery is performed. Specifically, when a game ball enters the operation port 84, it is detected by the operation port switch 154, and a ball detection signal is output from the operation port switch 154. When the incoming ball detection signal is input to the MPU 311, the value of the jackpot random number counter C1 at that time is acquired. Then, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1.

  Here, an illegal act using an illegal substrate called “hanging substrate” may be performed. The fraudulent act is to illegally generate a jackpot state by hanging an unauthorized substrate with respect to a regular control substrate. Specifically, a counter that is synchronized with the jackpot random number counter C1 is provided in the “hanging board”, and the value of the counter is reset to “0” in accordance with the power-on of the pachinko machine 10, etc. Then, the occurrence timing of the jackpot state, that is, the timing at which the value of the jackpot random number counter C1 matches the winning value predetermined as the jackpot winning is grasped. Then, in accordance with the occurrence timing of the jackpot state, an illegal entry detection signal is output from the “hanging board” to illegally generate the jackpot state.

  On the other hand, in this embodiment, an irregular delay circuit 602 is provided in the middle of the signal path from the reset circuit 601 to the MPU 311, and it is difficult to grasp the timing of winning a big hit by the irregular delay circuit 602. is doing.

  The irregular delay circuit 602 will be described in detail based on the block circuit diagram of FIG.

  The irregular delay circuit 602 is hardware including an integration circuit 611 and a NAND circuit 612. The NAND circuit 612 has two input terminals and an output terminal that outputs a signal corresponding to the input signals of the two input terminals. The two input terminals of the NAND circuit 612 and the reset circuit 601 are electrically connected via the signal line LN3 and the signal line LN4. An integrating circuit 611 is provided in the middle of the signal line LN4. That is, a signal line LN3 that does not pass through the integration circuit 611 and a signal line LN4 that passes through the integration circuit 611 are provided as a supply path from the reset circuit 601 to the NAND circuit 612.

  The integrating circuit 611 includes a capacitor 613 as charge / discharge means for storing and discharging electric charge, and a resistor 614. The capacitor 613 is connected in parallel with the resistor 614. More specifically, one end of the resistor 614 is connected to the reset circuit 601, and the other end is connected to the input terminal of the NAND circuit 612 and to one end of the capacitor 613. The other end of the capacitor 613 is grounded. In a state where the reset signal is output from the reset circuit 601, that is, in the power-on state of the pachinko machine 10, a voltage is applied to the capacitor 613 and a charged state is established. On the other hand, when the reset signal is not output, that is, when the pachinko machine 10 is in a power-off state, the capacitor 613 is in a discharged state, and the electric charge accumulated in the capacitor 613 is gradually released.

  A resistor 614 is connected to a path connecting the capacitor 613 and the reset circuit 601 in the signal line LN4. The resistor 614 has an electrical resistance, and the charge period in which the charge is accumulated up to a predetermined amount from the start of the accumulation of the charge in the capacitor 613 by the resistance value of the resistor 614 and the capacitance of the capacitor 613, and the accumulated The discharge period from the start of charge discharge until the stored charge is lost is determined. Specifically, if the time constant, which is a numerical value obtained by multiplying the electric capacity of the capacitor 613 by the resistance value of the resistor 614, is large, the charging period and the discharging period are long. On the other hand, if the time constant is small, the charge / discharge period is short. Note that the resistor 614 is not essential, and may be arbitrary as long as it has electrical resistance.

  The NAND circuit 612 is electrically connected to the reset circuit 601 by a signal line LN4 that passes through the integrating circuit 611 and a signal line LN3 that does not pass through the integrating circuit 611, and a reset signal is output from the reset circuit 601. The Further, the output terminal of the NAND circuit 612 and the MPU 311 are electrically connected. The NAND circuit 612 is connected to the power interruption monitoring substrate 302 via an electric path (not shown) and is supplied with operating power.

  The NAND circuit 612 outputs a LOW level signal to the MPU 311 when a reset signal that is an HI level signal from both the signal line LN3 and the signal line LN4 is input. When the signal is input, the MPU 311 operates (becomes an operating state). Thereby, the update of the jackpot random number counter C1 is started. That is, the LOW level signal output from the NAND circuit 612 corresponds to the update start signal. On the other hand, when a reset signal that is an HI level signal is not input from at least one of the signal line LN3 and the signal line LN4, the NAND circuit 612 outputs an HI level signal. In this situation, the MPU 311 enters an inoperative state, and the update of the big hit random number counter C1 is stopped. That is, the HI level signal output from the NAND circuit 612 corresponds to the stop signal. From the above, since the MPU 311 does not operate when the LOW level signal is not input from the NAND circuit 612, the MPU 311 does not operate even when a voltage is applied to the MPU 311 due to noise or the like. Therefore, malfunction of the MPU 311 due to noise can be prevented.

  Next, the operation of the integrating circuit 611 when the pachinko machine 10 is turned on will be described based on the timing chart of FIG.

  When the pachinko machine 10 enters the power-on state at the timing t10, generation of + 5V voltage is started in the power-on power supply unit 321a, and a reset signal at the HI level is output from the reset circuit 601. . The reset signal is input to the NAND circuit 612 via the signal line LN3 and the signal line LN4. Here, the reset signal input to the NAND circuit 612 via the signal line LN3 is the same as the waveform output from the reset circuit 601, while the reset signal input to the NAND circuit 612 via the signal line LN4. The input timing is delayed by a transient phenomenon of the integration circuit 611.

  Specifically, when a reset signal having an HI level is output from the reset circuit 601, a voltage corresponding to the HI level signal is applied to the integrating circuit 611. Then, the capacitor 613 of the integration circuit 611 is charged, and charges are accumulated in the capacitor 613. In this state, the voltage corresponding to the HI level signal is applied to the capacitor 613, and the voltage applied to the NAND circuit 612 is at the LOW level. As the time elapses, the amount of charge accumulated in the capacitor 613 increases, and the input voltage applied to the NAND circuit 612 increases.

  Thereafter, at the timing of t11, the input voltage from the signal line LN4 of the NAND circuit 612 becomes equal to or higher than the reference voltage Va, which is a voltage that the NAND circuit 612 recognizes as the HI level signal. Thereby, the NAND circuit 612 recognizes that the HI level signal is input from the signal line LN4. Then, a LOW level signal that is an update start signal is output to the MPU 311 by the NAND circuit 612, and the MPU 311 starts to operate accordingly. In other words, the output state of the NAND circuit 612 is switched when a predetermined amount of charge is accumulated. In other words, when a predetermined amount of charge is accumulated, the state of the signal supplied to the NAND circuit 612 is shifted to an operable state. Then, a random number counter updating process such as a big hit random number counter C1 is executed. That is, the output timing of the LOW level signal from the NAND circuit 612 with respect to the output timing of the HI level signal from the reset circuit 601 is delayed by the integration circuit 611 by the delay period DT1 from the timing t10 to the timing t11.

  After that, when the power supply from the external power source in the pachinko machine 10 is OFF at the timing t12, that is, when the pachinko machine 10 is in the power interruption state, the reset signal from the reset circuit 601 is not output. That is, the reset signal output from the reset circuit 601 is switched from the HI level to the LOW level. Corresponding to the switching, the input signal from the signal line LN3 of the NAND circuit 612 is immediately switched from the HI level to the LOW level. As a result, the NAND circuit 612 outputs a HI level that is a stop signal, and the MPU 311 is inactivated by specifying that the input signal has been switched to the HI level by the MPU 311. Thereby, the operation of the MPU 311 can be stopped immediately regardless of the integration circuit 611.

  On the other hand, when the output of the reset signal at the HI level is stopped, the capacitor 613 in the integration circuit 611 is discharged, and the charge accumulated in the capacitor 613 is gradually released over time. Thereby, a voltage due to the residual charge accumulated in the capacitor 613 is applied to the NAND circuit 612 from the signal line LN4. Such voltage gradually decreases as the charge accumulated in the capacitor 613 is released. Therefore, the timing at which the LOW level signal output from the reset circuit 601 via the signal line LN4 is input to the NAND circuit 612 is delayed as in the case of the reset signal.

  That is, the NAND circuit 612 does not output the LOW level signal that operates the MPU 311 until the reset signal that is at the HI level delayed by the integrating circuit 611 is input, while the reset signal is not output from the reset circuit 601. That is, when the output from the reset circuit 601 is switched from the HI level to the LOW level, the HI level signal as a stop signal is immediately output to the MPU 311 based on the LOW level signal regardless of the integration circuit 611. It has become. As a result, when the reset signal is output, the start timing of the operation of the MPU 311 is delayed by the integration circuit 611. On the other hand, when the reset signal is not output, the operation of the MPU 311 is quickly stopped. it can.

  Thereafter, when the pachinko machine 10 is turned on again at the timing t13, the capacitor 613 is charged again and accumulates electric charge. Then, when the input voltage from the signal line LN4 of the NAND circuit 612 becomes equal to or higher than the reference voltage Va at the timing t14, an HI level signal is input from the signal line LN4 to the NAND circuit 612, and accordingly, the NAND circuit 612 A LOW level signal is output to the MPU 311.

  Here, a reset signal at the HI level is output from the reset circuit 601 and the input voltage to the NAND circuit 612 is equal to or higher than the reference voltage Va, that is, a delay period in which the HI level signal is input to the NAND circuit 612 is at the HI level. It fluctuates depending on the residual charge amount of the capacitor 613 at the time when a certain reset signal is output. Specifically, the period for completing the charging of the capacitor 613 is shortened by the amount of residual charge at the time when the reset signal at the HI level is output, and the timing at which the MPU 311 starts operation is advanced. Here, at the timings t10 and t13 when the reset signal is output, the voltage from the signal line LN4 is not applied to the NAND circuit 612 at the timing t10, so that the charge remains in the capacitor 613. It can be said that it is not. On the other hand, at the timing of t13, since a voltage is applied from the signal line LN4 to the NAND circuit 612, it can be said that the electric charge remains in the capacitor 613. Therefore, the delay period DT1 from the timing t13 to the timing t11 when the signal input to the NAND circuit 612 is switched from the LOW level signal to the HI level signal is input to the NAND circuit 612 from the timing t13. Is longer than the delay period DT2 until the timing t14, which is the timing at which the signal to be switched from the LOW level signal to the HI level signal.

  A series of operations from the timing t15 to the timing t17 are the same as the operations from the timing t12 to the timing t14. However, the residual charge is as much as the period from the timing t15 when the pachinko machine 10 is turned off to the timing t16 when the pachinko machine 10 is switched to the power-on state is shorter than the period from the timing t15 to the timing t16. The amount is increasing. Therefore, the delay period DT3 from the timing t16 when the pachinko machine 10 is turned on to the timing when the input voltage from the signal line LN4 becomes the reference voltage Va with respect to the NAND circuit 612 is the other delay periods DT1 and DT2. Is shorter.

  From the above, the delay period from the output timing of the reset signal from the reset circuit 601 to the output timing of the LOW level signal from the NAND circuit 612 varies depending on the residual charge amount at the time when the pachinko machine 10 enters the power-on state. is doing. Specifically, the delay period becomes shorter as the residual charge amount increases. Further, the residual charge amount depends on a period from when the pachinko machine 10 is in a power-off state to when it is in a power-on state. Specifically, the amount of residual charge gradually decreases after the power interruption state. That is, the output timing of the LOW level signal from the NAND circuit 612 varies depending on the period from when the pachinko machine 10 is turned off to when it is turned on.

  According to the fifth embodiment described in detail above, the following excellent effects are obtained.

  An irregular delay circuit 602 is provided in the middle of the supply path from the reset circuit 601 to the NAND circuit 612. The irregular delay circuit 602 delays the output timing of the LOW level signal from the NAND circuit 612 with respect to the output timing of the reset signal from the reset circuit 601. The delay period varies depending on the output timing of the reset circuit 601. Thereby, since the delay period varies, the period from the start timing of power supply to the pachinko machine 10 to the update start timing of the big hit random number counter C1 is irregular. Therefore, even if the update process of the big hit random number counter C1 is started from a predetermined initial value when the power supply to the pachinko machine 10 is started, it is difficult to grasp the timing of winning the big hit. Accordingly, fraudulent acts using a “hanging board” or the like can be prevented. Note that the irregular delay circuit 602 is designated as “non-periodic circuit” or “unregulated circuit” by focusing on the function of changing the period from the reset signal output timing to the operation start timing of the MPU 311 according to the reset signal output timing. It can also be referred to as a “periodic delay circuit”.

  Specifically, an integration circuit 611 is provided as the irregular delay circuit 602, and the capacitor 613 of the integration circuit 611 is charged by a reset signal. The reset signal is input to the NAND circuit 612 when the amount of charge accumulated in the capacitor 613 exceeds a predetermined amount. As a result, the reset signal input to the NAND circuit 612 is delayed from the reset signal output timing from the reset circuit 601 until a predetermined amount or more of charge is accumulated in the capacitor 613. Therefore, the LOW from the NAND circuit 612 is delayed. The output timing of the level signal is delayed. The delay period varies depending on the residual charge amount at the time when the reset signal is output. Further, the residual charge amount varies depending on a period from when the pachinko machine 10 is in a power-off state to when it is in a power-on state. That is, the delay period varies according to the output timing of the reset signal. Therefore, the period from the output timing of the reset signal from the reset circuit 601 to the output timing of the LOW level signal from the NAND circuit 612 is irregular. Thereby, it is difficult to grasp the timing of winning the jackpot. Therefore, the integrating circuit 611 can prevent an illegal act using a “hanging board” or the like.

  In particular, the integration circuit 611 in the present embodiment is a simple circuit including one capacitor 613 and one resistor 614. Even with this simple configuration, the period from the output timing of the reset signal from the reset circuit 601 to the output timing of the LOW level signal from the NAND circuit 612 can be made irregular. Thereby, it is possible to prevent an illegal act using a “hanging board” or the like with a simple configuration.

  In addition, in the case where fraudulent acts using the “hanging board” or the like are continuously performed, it is assumed that the pachinko machine 10 is switched between a power-on state and a power-off state in a relatively short time. On the other hand, the residual charge amount of the capacitor 613 in the integration circuit 611 changes greatly as the period from when the pachinko machine 10 is turned off to when it is turned on becomes shorter. This is particularly effective when performing fraud using "

  The charging period and discharging period of the capacitor 613 are determined by the electric resistance of the resistor 614 and the capacitance of the capacitor 613. Accordingly, the range of variation in the delay period can be increased by lengthening the charging period and the discharging period. Therefore, since the variation in the delay period can be increased, the delay period can be made more irregular. Therefore, it is difficult to grasp the timing of winning the jackpot.

  Further, the amount of charge accumulated in the capacitor 613 varies depending on the number of times the capacitor 613 is charged and the number of times the charge accumulated in the capacitor 613 is discharged. Specifically, it is conceivable that the insulating film deteriorates due to an electric field applied to the insulating film of the capacitor 613. Then, the maximum charge amount and the capacitance accumulated in the capacitor 613 change, and the residual charge amount fluctuates. Thereby, since the delay period becomes more irregular, it is possible to make it difficult to grasp the timing of winning the big hit.

  As a supply path from the reset circuit 601 to the NAND circuit 612, a signal line LN3 that does not pass through the integration circuit 611 and a signal line LN4 that passes through the integration circuit 611 are provided. The NAND circuit 612 outputs a LOW level signal for operating the MPU 311 when a reset signal having an HI level is input from both the signal line LN3 and the signal line LN4, while at least one of the signal line LN3 or the signal line LN4. When the reset signal at the HI level is no longer input from, the HI level signal that is a stop signal for stopping the operation of the MPU 311 is output. As a result, when the reset signal is no longer output while ensuring the delay of the reset signal by the integration circuit 611, a stop signal is output from the NAND circuit 612 to the MPU 311 regardless of the integration circuit 611. Thereby, it is possible to prevent the MPU 311 from malfunctioning by delaying the output timing of the stop signal.

  Note that the resistance value of the resistor 614 and the capacitor 613 may be changed for each gaming machine. According to such a configuration, since the discharging period and the charging period are different for each gaming machine, it is possible to make it harder to grasp the timing of winning the jackpot.

<Sixth Embodiment>
In the present embodiment, the configuration relating to the irregular delay circuit 602 is different from that of the fifth embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the fifth embodiment will be mainly described, and description of the same configuration will be basically omitted. In the sixth embodiment, the irregular delay circuit 602 has a configuration shown in FIG. 33 instead of the configuration shown in FIG. 31 so that the charging period and the discharging period are different.

  The irregular delay circuit 602 is provided with a switching circuit 621. The switching circuit 621 is disposed on a path connecting the reset circuit 601 and the integrating circuit 611. A reset signal output from the reset circuit 601 is input to the NAND circuit 612 via the switching circuit 621 and the integration circuit 611.

  The switching circuit 621 includes a diode 622 as a rectifier and an adjustment resistor 623 that adjusts a discharge period with respect to a charge period. The diode 622 is connected in such a manner that the direction from the reset circuit 601 toward the integrating circuit 611 is a forward direction. Specifically, the anode side of the diode 622 is connected to the reset circuit 601, and the cathode side is connected to one end of the resistor 614 of the integrating circuit 611. The adjustment resistor 623 is connected in parallel to the diode 622. Specifically, one end of the adjustment resistor 623 is connected to the anode side of the diode 622, and the other end is connected to the cathode side of the diode 622. With this configuration, since the charging period and discharging period of the capacitor 613 of the integration circuit 611 are different, the MPU 311 can be quickly started up while ensuring variation in the delay period.

  Specifically, when a reset signal is output from the reset circuit 601, a forward voltage flows through the diode 622, so a forward current flows. Then, a voltage corresponding to the reset signal is applied to the integration circuit 611, and the capacitor 613 is charged. Thereby, the output timing of the LOW level signal from the NAND circuit 612 with respect to the output timing of the reset signal from the reset circuit 601 is delayed. Here, the delay period, that is, the charging period until a predetermined amount of charge is accumulated in the capacitor 613 depends on the resistance value of the resistor 614 and the capacitance of the capacitor 613.

  On the other hand, when the output of the reset signal from the reset circuit 601 is stopped, that is, when the reset signal is switched from the HI level signal to the LOW level signal, the capacitor 613 is discharged, and the charge accumulated in the capacitor 613 is released. The Here, the electric charge accumulated in the capacitor 613 does not pass through the diode 622. Therefore, the electric charge accumulated in the capacitor 613 is discharged through the resistor 614 of the integrating circuit 611 and the adjusting resistor 623 connected in parallel to the diode 622. That is, the discharge period depends on the resistance value of the adjustment resistor 623 in addition to the resistor 614 and the capacitor 613. Therefore, the charging period and discharging period of the capacitor 613 are different. More specifically, since the time constant in discharging becomes larger than the time constant in charging as much as it depends on the adjustment resistor 623, the discharging period becomes slower than the charging period. That is, by connecting the diode 622 as a rectifier and the adjustment resistor 623 in parallel to the diode 622, the discharge period is relatively longer than the charge period.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A switching circuit 621 that makes the discharging period relatively longer than the charging period of the capacitor 613 in the integrating circuit 611 is provided. Thereby, the start timing of the operation of the MPU 311 can be made irregular and quick while ensuring the variation of the delay period.

  In order to widen the variation range of the delay period and increase the variation of the delay period, it is preferable to lengthen the charge period and the discharge period. In particular, it is preferable that the discharge period contributing to the variation in the residual charge amount is long. Further, in order to cause variation in the delay period even in a long-term power interruption state, a longer discharge period is preferable. In order to lengthen the discharge period, it is conceivable to increase the resistance value of the resistor 614 of the integrating circuit 611 or the capacitance of the capacitor 613. However, since only the integrating circuit 611 has the same charging period and discharging period, the charging period also becomes longer. Then, the start timing of the operation of the MPU 311 may be excessively delayed. On the other hand, in the present embodiment, the switching circuit 621 makes the discharging period longer than the charging period. Thereby, it is suppressed that the start timing of the operation of the MPU 311 is excessively delayed while ensuring the variation of the delay period.

  In addition to the adjustment resistor 623 or in addition to the adjustment resistor 623, the integration circuit 611 is connected to the adjustment capacitor in series with the capacitor 613 and the adjustment capacitor in the charged state, and the capacitor 613 and the adjustment capacitor in the discharged state. It is good also as a structure which provides the switching means connected in parallel. According to such a configuration, the combined capacity of the capacitor 613 and the adjustment capacitor in the discharged state becomes larger than that in the charged state, so that the discharge period can be made longer than the charged period.

  Further, although the diode 622 is used as the rectifier, the present invention is not limited to this. For example, instead of the diode 622, the diode 622 is turned on when a reset signal is output from the reset circuit 601, and the reset signal is not output. A switching element that is turned off may be provided. In short, what is necessary is just to flow an electric current in one direction.

<Seventh Embodiment>
In the present embodiment, the configuration relating to the irregular delay circuit 602 is different from that of the fifth embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the fifth embodiment will be mainly described, and description of the same configuration will be basically omitted. In the seventh embodiment, the configuration shown in FIGS. 34 to 36 is used instead of the configuration shown in FIGS.

  The power source and launch control board 321 is provided with an AC power source unit 631 that outputs an AC voltage. Unlike the AC power supply unit 321d of the first embodiment or the like, the AC power supply unit 631 has a full-wave rectifier circuit as a waveform shaping means for adjusting the voltage waveform, and a + 24V AC voltage supplied from a commercial power supply. Output waveform is rectified in one direction. The AC power supply unit 631 is always supplied with power from a commercial power source regardless of the power-on state and power-off state of the pachinko machine 10.

  The power interruption monitoring board 302 includes a power failure monitoring circuit 632 that monitors the voltage and a signal conversion circuit 402 that converts the AC voltage into a pulse signal. The power failure monitoring circuit 632 monitors the voltage of DC stability + 24V, which is the maximum voltage output from the power supply and launch control board 321. When this voltage is equal to or higher than a predetermined voltage, an HI level signal is output to the main control board 301. When this voltage becomes lower than the predetermined voltage, it is determined that the power is cut off, and the main control board 301 is And outputs a LOW level signal as a power failure signal.

  As described in the first embodiment, the signal conversion circuit 402 is a circuit that converts the AC voltage output from the AC power supply unit 631 into a pulse signal. The pulse signal is output to the irregular delay circuit 602.

  A connection relationship between the signal conversion circuit 402, the irregular delay circuit 602, and the MPU 311 will be described in detail based on the block diagram of FIG.

  Here, the Schmitt trigger 413 is electrically connected to the power supply and launch control board 321 via an electrical path (not shown), and the pachinko machine 10 is connected by the power-on power supply unit 321a and the power-off power supply unit 321c. Power is supplied regardless of the power-on state and power-off state. As already described, the Schmitt trigger 413 outputs a LOW level signal if it is equal to or higher than the predetermined upper threshold voltage Vth, and outputs an HI level signal if it is lower than the predetermined lower threshold voltage Vtl. Specifically, when the AC voltage becomes equal to or higher than the upper limit threshold voltage Vth (for example, +4.3 V), the LOW level signal is subsequently output until the AC voltage becomes lower than the lower limit threshold voltage Vtl (for example, +3.5 V) lower than the upper limit threshold voltage Vth. When the AC voltage becomes lower than the lower limit threshold voltage Vtl, the HI level signal is output until the AC voltage becomes the upper limit threshold voltage Vth. Thereby, a pulse signal having a predetermined pulse width is obtained. In other words, by converting the AC voltage into a pulse signal, a specific signal that alternately outputs the HI level signal and the LOW level signal is generated. Further, since the AC voltage is rectified in one direction by the full-wave rectifier circuit, the frequency of the pulse signal is doubled compared to the case where the normal AC voltage is converted into a pulse signal. Therefore, the operation process of the irregular delay circuit 602 using the pulse signal can be suitably performed.

  Further, the pulse width of the pulse signal can be adjusted by adjusting the upper threshold voltage Vth and the lower threshold voltage Vtl of the Schmitt trigger 413. Specifically, when the upper threshold voltage Vth and the lower threshold voltage Vtl are brought close to 0 and the ranges of the upper threshold voltage Vth and the lower threshold voltage Vtl are narrowed, a pulse signal having a narrow pulse width can be obtained. That is, the Schmitt trigger 413 is a conversion unit that converts an AC voltage into a pulse signal and a pulse width adjustment unit that adjusts the pulse width of the pulse signal.

  The AC power supply unit 631 is connected to a commercial power supply and is always supplied with power, and outputs an AC voltage. That is, the AC voltage is not affected by the power-on state and power-off state of the pachinko machine 10. Electric power is supplied to the Schmitt trigger 413 regardless of the power-on state and power-off state of the pachinko machine 10. Therefore, the pulse signal obtained by converting the AC voltage is not affected by the power-on state and power-off state of the pachinko machine 10. In other words, the form of the pulse signal is random with respect to the output timing of the reset signal.

  When a reset signal is output from the reset circuit 601, a signal for operating the MPU 311 is output from the irregular delay circuit 602 based on the form of the pulse signal input from the Schmitt trigger 413. The configuration will be described in detail.

  The irregular delay circuit 602 includes a synthesis circuit 641 and a D flip-flop 642 instead of the integration circuit 611. The synthesizing circuit 641, the D flip-flop 642, and the NAND circuit 612 are connected to the power supply and launch control board 321 via an electrical path and power interruption monitoring board 302 (not shown), respectively, and receive power supply from the power supply and launch control board 321. ing.

  The combining circuit 641 includes an AND circuit, and has two input terminals and an output terminal that outputs a signal based on signals from the two input terminals. One input terminal of the synthesis circuit 641 and the output terminal of the Schmitt trigger 413 are connected. The pulse signal output from the Schmitt trigger 413 is supplied to the synthesis circuit 641. Further, the other input terminal of the synthesis circuit 641 and the reset circuit 601 are connected. The reset signal output from the reset circuit 601 is supplied to the synthesis circuit 641. The synthesis circuit 641 inputs the HI level synthesis reset signal to the D flip-flop 642 only when the reset signal having the HI level is input from the reset circuit 601 and the HI level signal is input from the Schmitt trigger 413. Output. On the other hand, when the reset signal is not input or when the signal input from the Schmitt trigger 413 is not the HI level signal, the combining circuit 641 does not output the combined reset signal. Therefore, the output timing of the composite reset signal is delayed until the HI level signal is output.

  The D flip-flop 642 has a data terminal (D terminal) and a clock terminal (CLK terminal) as input terminals, and a positive logic output terminal (Q terminal) as an output terminal. A reset circuit 601 is connected to the D terminal, and an output terminal of the synthesis circuit 641 is connected to the CLK terminal. A NAND circuit 612 is connected to the Q terminal.

  The D flip-flop 642 outputs a reset signal at the HI level to the NAND circuit 612 while ensuring the delay caused by the synthesis circuit 641, while holding the reset signal once output regardless of the synthesis circuit 641. It has a function to do. As a result, after the reset signal is once output from the combining circuit 641, the output to the NAND circuit 612 is retained even when the combined reset signal output from the combining circuit 641 fluctuates. Therefore, the inconvenience that the operation of the MPU 311 stops due to the fluctuation of the composite reset signal can be suppressed.

  Specifically, the D flip-flop 642 receives a reset signal that is at the HI level at the timing when the composite reset signal is input to the CLK terminal from the composite circuit 641 (more specifically, the rising timing of the composite reset signal). If it is, the HI level signal is output to the NAND circuit 612. The HI level signal is continuously output until the reset signal is not input at the timing when the composite reset signal is input to the CLK terminal. In other words, it can be said that the D flip-flop 642 holds the input state of the reset signal until the combined reset signal is input to the CLK terminal.

  Here, the operations of the synthesis circuit 641 and the D flip-flop 642 will be described based on the timing chart of FIG.

  When the power of the pachinko machine 10 is ON at the timing t18, that is, when the pachinko machine 10 is turned on, a reset signal is output from the reset circuit 601. More specifically, the reset circuit 601 outputs a HI level signal. Then, a reset signal is input to the D terminal of the D flip-flop 642 and a reset signal is input to the synthesis circuit 641. On the other hand, since the output signal from the Schmitt trigger 413 is a LOW level signal, the synthesis circuit 641 outputs a LOW level signal. In such a state, the D flip-flop 642 holds the LOW level signal. Therefore, the MPU 311 does not start operation.

  When the output signal from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t19, the synthesis circuit 641 outputs the HI level signal. Then, the signal input to the CLK terminal of the D flip-flop 642 rises from the LOW level to the HI level. In such a case, the D flip-flop 642 outputs a signal corresponding to the input state of the signal input to the D terminal at that time from the Q terminal. Here, since the reset signal at the HI level is input to the D terminal, the HI level signal is output from the Q terminal. The reset signal is input to the NAND circuit 612. As a result, a LOW level signal is output from the NAND circuit 612, and the operation of the MPU 311 is started.

  That is, the start timing of the operation of the MPU 311 is delayed by the synthesis circuit 641 by the delay period DT4 until the signal output from the Schmitt trigger 413 becomes the HI level signal after the pachinko machine 10 is turned on. Yes. Here, since the pulse signal fluctuates regardless of whether the pachinko machine 10 is in the power-on state or the power-off state, the form of the pulse signal varies depending on the timing at which the pachinko machine 10 is in the power-on state. Therefore, the delay period DT4, which is a period from the timing when the pachinko machine 10 enters the power-on state to the timing when the pachinko machine 10 enters the HI-level state, which is one of the pulse signal forms, corresponds to the timing when the pachinko machine 10 enters the power-on state Fluctuate. Therefore, the delay period DT4 is irregular.

  After that, when the output signal from the Schmitt trigger 413 switches from the HI level to the LOW level at the timing of t20, the combined reset signal output from the combining circuit 641 also switches from the HI level to the LOW level, and the CLK terminal of the D flip-flop 642 The signal input to HI also switches from the HI level to the LOW level. However, the D flip-flop 642 is a signal input to the D terminal in synchronization with the timing at which the composite reset signal at the HI level is input to the CLK terminal, that is, the timing at which the composite reset signal switches from the LOW level to the HI level. A signal corresponding to the input state is output from the Q terminal, and is not synchronized at the timing when the composite reset signal is switched from the HI level to the LOW level. Therefore, the signal state output from the Q terminal is maintained.

  When the signal output from the Schmitt trigger 413 is switched from the LOW level to the HI level at the timing t21, the synthesis reset signal having the HI level is output from the synthesis circuit 641. Specifically, the signal output from the synthesis circuit 641 is switched from the LOW level to the HI level. Then, since the signal input to the CLK terminal is also switched from the LOW level to the HI level, the D flip-flop 642 outputs a signal corresponding to the signal input to the D terminal at that time from the Q terminal. In such a case, since the reset signal at the HI level is input to the D terminal, the signal output from the Q terminal is also the HI level signal. Therefore, the signal output from the NAND circuit 612 maintains the LOW level. That is, once the HI level signal is output from the Q terminal, the signal output from the Schmitt trigger 413 is alternately switched between the HI level and the LOW level, so that the composite reset signal is alternately switched between the HI level and the LOW level. Even if the signal is switched, the HI level signal output from the Q terminal does not change unless the signal input to the D terminal changes. Therefore, the malfunction of the MPU 311 due to the change in the signal output from the Schmitt trigger 413 is suppressed by the D flip-flop 642.

  When the pachinko machine 10 is turned off at the timing t22, the LOW level signal is immediately input from the signal line LN3 to the NAND circuit 612, and the HI level signal is output from the NAND circuit 612 to the MPU 311. Therefore, the MPU 311 falls immediately. On the other hand, the AC power supply unit 631 is connected to a commercial power supply and receives power supply and outputs a full-wave waveform AC voltage regardless of the power interruption state of the pachinko machine 10. A pulse signal obtained by converting the AC voltage is output regardless of the interruption state. Since the D flip-flop 642 has a volatile configuration, the output state from the Q terminal is not maintained. In this case, the output state from the Q terminal may become unstable. In this state, when the output state from the Q terminal is at the HI level, the signal output from the NAND circuit 612 becomes the LOW level, and the operation of the MPU 311 may not be completed. On the other hand, according to this embodiment, since the LOW level signal is input from the signal line LN3, the operation of the MPU 311 can be ended regardless of the output state from the signal line LN4. As a result, the MPU 311 can be reliably lowered. If the output state from the Q terminal is at the LOW level, the MPU 311 falls immediately.

  When the pachinko machine 10 is turned on again at the timing of t23, a reset signal that is at the HI level is output in the same manner as the timing of t27, and accordingly, one end on the input side of the synthesis circuit 641 and D of the D flip-flop 642 A HI level reset signal is input to the terminal. In such a case, since the signal output from the Schmitt trigger 413 to the synthesis circuit 641 is a LOW level signal, the synthesis circuit 641 outputs a LOW level signal. Since the D flip-flop 642 is not synchronized with the output of the signal, the current output state is maintained. Therefore, the MPU 311 does not start operation.

  When the signal output from the Schmitt trigger 413 is switched from the LOW level to the HI level at the timing t24, the output signal from the synthesis circuit 641 rises from the LOW level to the HI level as in the case of the timing t19. In synchronization with the rise, the D flip-flop 642 outputs a signal corresponding to the input state. Specifically, since the HI level reset signal is input to the D terminal, the HI level signal is output from the Q terminal. Then, a LOW level signal is output from the NAND circuit 612 to the MPU 311, and the MPU 311 starts operation upon receiving the signal. Therefore, the operation start timing of the MPU 311 is delayed by the delay period DT5 from the timing t23 to the timing t24.

  Here, the delay periods DT4 and DT5 are from the timing when the pachinko machine 10 is turned on, that is, from the output timing of the reset signal from the reset circuit 601 until the signal output from the Schmitt trigger 413 becomes the HI level signal. Since this is the period, the period until the output signal from the Schmitt trigger 413 changes from the HI level signal to the next HI level signal is within the variation range of the delay period. That is, the period of the LOW level signal is within the range of variation of the delay period. When the reset signal is output within the period of the LOW level signal, that is, when the pachinko machine 10 is in the power-on state, the timing at which the LOW level signal is output from the NAND circuit 612 is the timing at which the power-on state is reached. Has been delayed based. Thereby, since the delay period is irregular, it is difficult to grasp the start timing of the random number counter update process. Therefore, an illegal act using a “hanging board” or the like can be prevented.

  When the pachinko machine 10 is turned off at the timing of t25, the MPU 311 falls immediately as in the case of the timing of t22.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A synthesis circuit 641 is provided as the irregular delay circuit 602, and the synthesis circuit 641 receives from the signal conversion circuit 402, more specifically, from the Schmitt trigger 413, when a reset signal having an HI level is input from the reset circuit 601. Based on the specific form of the pulse signal to be output, the composite reset signal at the HI level is output. Specifically, the synthesis circuit 641 is configured to output a synthesis reset signal at the HI level based on the fact that the signal output from the signal conversion circuit 402 is at the HI level. Thereby, when the reset signal is output in a state where the signal output from the signal conversion circuit 402 is at the LOW level, the output of the combined reset signal is delayed until the HI level signal is output. The output of the HI level signal to the NAND circuit 612 is delayed. In response to the input of the HI level signal, the NAND circuit 612 outputs a LOW level signal to the MPU 311. In response to the input of the LOW level signal, the MPU 311 starts operation. In other words, the state of the signal supplied to the NAND circuit 612 shifts to an operable state based on the signal output from the signal conversion circuit 402 becoming HI level. In other words, when the signal output from the Schmitt trigger 413 becomes the HI level, the state of the signal supplied to the MPU 311 is switched to the operable state.

  Here, the form of the pulse signal varies depending on the timing at which the pachinko machine 10 enters the power-on state. Thereby, the period from the timing when the pachinko machine 10 enters the power-on state to the output timing of the composite reset signal from the synthesis circuit 641 varies depending on the timing when the pachinko machine 10 enters the power-on state. Therefore, the output timing of the LOW level signal from the NAND circuit 612 is irregular. Therefore, since it is difficult to grasp the update start timing of the jackpot random number counter C1, it is difficult to grasp the timing of winning the jackpot. Thereby, fraudulent acts using a “hanging board” or the like can be suppressed.

  Further, in the case where the integration circuit 611 is provided as the irregular delay circuit 602, if the period of the power interruption state of the pachinko machine 10 is longer than the discharge period, the charge does not remain in the capacitor 613 of the integration circuit 611. Inconvenience that does not occur. On the other hand, according to the configuration in which the LOW level signal is output from the NAND circuit 612 based on the form of the signal output from the signal conversion circuit 402, the delay period does not depend on the period of the interruption state of the pachinko machine 10. Therefore, the above inconvenience can be avoided.

  A signal conversion circuit 402 that converts an AC voltage supplied from the AC power supply unit 631 into a pulse signal is provided. Thereby, since the specific signal from which a HI level signal and a LOW level signal are output alternately from a commercial power supply can be obtained, the configuration can be simplified.

  In the above embodiment, when the signal output from the signal conversion circuit 402 is at the HI level, the combining circuit 641 outputs a reset signal at the HI level. However, the present invention is not limited to this, and the signal conversion circuit is not limited thereto. When the signal output from 402 is at the LOW level, the HI level signal may be output.

  In addition, when the pachinko machine 10 is turned on again at the timing t26, a reset signal is output. Accordingly, one end on the input side of the synthesis circuit 641 and the D signal of the D flip-flop 642 are at the HI level. Is entered. Further, since the signal input to the synthesis circuit 641 is at the HI level, the synthesis reset signal at the HI level is output from the synthesis circuit 641. Therefore, a HI level signal is output from the Q terminal of the D flip-flop 642 in synchronization with the signal. In such a case, a problem that no delay occurs occurs.

  On the other hand, the Schmitt trigger 413 has a function of adjusting the pulse width of the pulse signal. Specifically, the pulse width is adjusted by adjusting the upper threshold voltage and the lower threshold voltage of the Schmitt trigger 413. In particular, by making the upper threshold voltage and the lower threshold voltage of the Schmitt trigger 413 close to 0 and narrowing the range of the upper threshold voltage and the lower threshold voltage, the HI level state is compared with the LOW level state in one cycle of the pulse signal. Relatively short period. Then, the period in which no delay occurs is shorter than the period in which a delay occurs. Therefore, it is possible to avoid the problem that no delay occurs. In other words, in one cycle of the pulse signal, the HI level signal becomes a relatively short period compared to the LOW level signal, so that the range of variation of the delay period becomes wide. The irregularity of the delay period can be improved.

  Note that when the signal output from the signal conversion circuit 402 is configured to output an HI level signal under a LOW level state, the LOW level state is adjusted to be longer than the HI level state. Good.

<Eighth Embodiment>
In the present embodiment, the configuration relating to the irregular delay circuit 602 is different from that of the seventh embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the seventh embodiment will be mainly described, and description of the same configuration will be basically omitted. In the eighth embodiment, the configuration shown in FIGS. 37 and 38 is used instead of the configuration shown in FIGS.

  In the seventh embodiment, when the reset signal is output from the reset circuit 601 and the signal output from the signal conversion circuit 402 is the HI level signal, the synthesis circuit 641 outputs the HI level signal, The MPU 311 is configured to operate. Instead, the MPU 311 is configured to operate in synchronization with the rise of the pulse signal.

  The irregular delay circuit 602 has a D flip-flop 651 as a transition means. The D flip-flop 651 has a data terminal (D terminal) and a clock terminal (CLK terminal) as input terminals, and a positive logic output terminal (Q terminal) as an output terminal. A reset circuit 601 is connected to the D terminal, and a Schmitt trigger 413 is connected to the CLK terminal. A NAND circuit 612 is connected to the Q terminal.

  The D flip-flop 651 outputs a signal corresponding to the input state of the signal input to the D terminal from the Q terminal in synchronization with the signal input to the CLK terminal rising from the LOW level to the HI level. . That is, in synchronization with the rise of the pulse signal converted by the Schmitt trigger 413, a signal corresponding to the signal state output from the reset circuit 601 at that time is output from the Q terminal, and the signal is output until the next rise of the pulse signal. Holds the output state.

  The operation of the irregular delay circuit 602 will be described with reference to the timing chart of FIG.

  When the pachinko machine 10 is turned on at the timing t27, a reset signal is output from the reset circuit 601. More specifically, the reset circuit 601 outputs a HI level signal. Then, a HI level reset signal is input to the D terminal of the D flip-flop 651. On the other hand, since the output signal from the Schmitt trigger 413 is a LOW level signal, that is, a state in which there is no output, the D flip-flop 651 maintains the current output state without synchronizing. Therefore, a reset signal at the HI level is not output to the NAND circuit 612. Therefore, the MPU 311 does not start operation.

  When the output signal from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing t28, the D flip-flop 651 outputs a signal corresponding to the input state in synchronization with the rise. Here, since a reset signal at the HI level is input to the D terminal, an HI level signal is output from the Q terminal. The HI level signal is input to the NAND circuit 612. In other words, the state of the signal supplied to the NAND circuit 612 has shifted to the operable state. As a result, a LOW level signal is output from the NAND circuit 612, the operation of the MPU 311 is started, and the update of the random number counter update process such as the jackpot random number counter C1 is started.

  That is, the operation start timing of the MPU 311 is delayed by the delay period DT6 from when the pachinko machine 10 is turned on to when the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level. Here, since the pulse signal fluctuates regardless of whether the pachinko machine 10 is in the power-on state or the power-off state, the form of the pulse signal varies depending on the timing at which the pachinko machine 10 is in the power-on state. Therefore, the delay period DT6, which is a period from the timing when the pachinko machine 10 enters the power-on state to the rising timing from the LOW level signal, which is one of the pulse signal forms, to the HI level signal is the pachinko machine 10 in the power-on state. It fluctuates according to the timing. Therefore, the output timing of the LOW level signal from the NAND circuit 612 becomes irregular. Therefore, since the period from when the pachinko machine 10 is turned on to when the update of the jackpot random number counter C1 is started is irregular, it is difficult to grasp the timing of winning the jackpot.

  When the pachinko machine 10 is turned off at the timing t29, the LOW level signal is immediately input from the signal line LN3 to the NAND circuit 612 as in the case of the seventh embodiment, and the MPU 311 receives the HI signal. Since the level signal is output, the MPU 311 falls immediately. On the other hand, the AC power supply unit 631 is connected to a commercial power supply, and receives power supply and outputs an AC voltage having a full-wave waveform regardless of whether the pachinko machine 10 is turned on or off. Further, the Schmitt trigger 413 is supplied with power from the power supply unit 321c for power interruption even in a power interruption state. Therefore, the pulse signal obtained by converting the AC voltage from the AC power supply unit 631 is output regardless of the power interruption state. Since the D flip-flop 651 has a volatile configuration, the output state from the Q terminal is not held in the power-off state.

  When the pachinko machine 10 is turned on again at the timing t30, the reset signal rises in the same manner as the timing t27, and accordingly, a reset signal at the HI level is input to the D terminal of the D flip-flop 651. On the other hand, the signal input to the CLK terminal is an HI level signal, not the rising timing. Therefore, the D flip-flop 651 holds the LOW level signal.

  When the signal output from the Schmitt trigger 413 is switched from the LOW level to the HI level at the timing of t31, since the D flip-flop 651 receives the reset signal at the HI level at the D terminal, the HI level is output from the Q terminal. A signal is output. Then, a LOW level signal is output from the NAND circuit 612 to the MPU 311, and the MPU 311 starts operation upon receiving the signal. Therefore, the operation start timing of the MPU 311 is delayed by the delay period DT7 from the timing t30 to the timing t31.

  Here, since the delay periods DT6 and DT7 are the timing when the pachinko machine 10 enters the power-on state, that is, the period from the reset signal output timing from the reset circuit 601 to the rising timing of the pulse signal, the rising cycle is the delay period. It becomes the range of variation. That is, the cycle of the pulse signal is within the range of variation in the delay period. The delay period varies in accordance with the output timing of the reset signal from the reset circuit 601 within the range. Specifically, the period from the reset signal output timing to the rise timing of the pulse signal is longer than the period from the timing t27 to the timing t28, and the delay period DT7 is longer than the period from the timing t30 to the timing t31. Is longer than the delay period DT6. As a result, the delay period is irregular.

  According to the eighth embodiment described in detail above, the following excellent effects can be obtained.

  As the irregular delay circuit 602, a D flip-flop 651 for outputting a signal corresponding to the reset signal output from the reset circuit 601 to the NAND circuit 612 in synchronization with the rising edge of the pulse signal is provided. Thereby, when the reset signal is output from the reset circuit 601, the output timing of the LOW level signal from the NAND circuit 612 is delayed until the rising edge of the pulse signal. Then, in response to the input of the LOW level signal, the MPU 311 starts operation. In other words, under the state where the reset signal is output from the reset circuit 601, the state of the signal supplied to the NAND circuit 612 shifts to the operable state based on the rising edge of the pulse signal. In other words, the reset signal is output from the reset circuit 601, and the state of the signal supplied to the MPU 311 is switched to the operable state based on the rise of the pulse signal.

  Here, the form of the pulse signal varies depending on the timing at which the pachinko machine 10 is turned on. As a result, the period from when the pachinko machine 10 enters the power-on state to when the pulse signal rises varies depending on the timing when the pachinko machine 10 enters the power-on state. Therefore, the timing at which the D flip-flop 651 synchronizes, that is, the output timing of the LOW level signal from the NAND circuit 612 is irregular. Therefore, since it is difficult to grasp the update start timing of the jackpot random number counter C1, it is difficult to grasp the timing of winning the jackpot. Thereby, fraudulent acts using a “hanging board” or the like can be suppressed.

  In the pulse signal, the period from the rising timing to the next rising timing is the range of variation in the delay period. That is, the period of the pulse signal is within the range of variation in the delay period. Therefore, based on the fact that either one of the HI level signal and the LOW level signal is output from the signal conversion circuit 402, the delay period is compared with the configuration in which the composite reset signal having the HI level is output. The range of variation is wide. Therefore, it is more difficult to grasp the output timing of the LOW level signal from the NAND circuit 612.

  In other words, a delay occurs unless the rising edge of the pulse signal coincides with the timing at which the pachinko machine 10 enters the power-on state. In other words, the period during which no delay occurs is shorter compared to a configuration that is synchronized when the signal output from the signal conversion circuit 402 is at the HI level or the LOW level. Therefore, it is possible to suppress the problem that no delay occurs.

<Ninth Embodiment>
In the present embodiment, the configuration relating to the irregular delay circuit 602 is different from that in the eighth embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the eighth embodiment will be mainly described, and description of the same configuration will be basically omitted. In the ninth embodiment, the configuration shown in FIGS. 39 and 40 is used instead of the configuration shown in FIGS.

  In the present embodiment, the rising cycle of the pulse signal used for defining the timing to synchronize is changed.

  The irregular delay circuit 602 includes a first D flip-flop 661 and a modulation circuit 662. Similar to the D flip-flop 651 described in the seventh embodiment, the first D flip-flop 661 includes a D1 terminal and a CLK1 terminal as input terminals, and a Q1 terminal as an output terminal. Similarly to the D flip-flop 651, the Q1 terminal is connected to the input terminal of the NAND circuit 612, and the D1 terminal is connected to the reset circuit 601. The modulation circuit 662 is provided on a path connecting the first D flip-flop 661 and the Schmitt trigger 413 that converts an AC voltage into a pulse signal. The pulse signal output from the Schmitt trigger 413 is input to the CLK1 terminal of the first D flip-flop 661 via the modulation circuit 662. The modulation circuit 662 includes a second D flip-flop 663, a third D flip-flop 664, and an XOR circuit 665. The second D flip-flop 663, the third D flip-flop 664, and the XOR circuit 665 are electrically connected to the power supply unit 321a for turning on the power supply and the firing control board 321 through the electric path and the power interruption monitoring board 302 (not shown), respectively. Connected. Therefore, while the power-on power supply unit 321a supplies power, that is, while the pachinko machine 10 is in the power-on state, the second D flip-flop 663, the third D flip-flop 664, and the XOR circuit 665 Works.

  The XOR circuit 665 has two input terminals and an output terminal that outputs a signal corresponding to a signal input to the input terminal. Similar to the first D flip-flop 661, the second D flip-flop 663 has a D2 terminal and a CLK2 terminal as input terminals, and a Q2 terminal as an output terminal. Similarly to the first D flip-flop 661, the third D flip-flop 664 has a D3 terminal and a CLK3 terminal as input terminals, and a Q3 terminal as an output terminal. The output terminal of the XOR circuit 665 is connected to the D2 terminal of the second D flip-flop 663, and the output terminal of the Schmitt trigger 413 is connected to the CLK2 terminal. The D3 terminal of the third D flip-flop 664 is connected to the Q2 terminal of the second D flip-flop 663. Similarly to the second D flip-flop 663, the output terminal of the Schmitt trigger 413 is connected to the CLK3 terminal of the third D flip-flop 664. The Q3 terminal of the third D flip-flop 664 is connected to the CLK1 terminal of the first D flip-flop 661, and is connected to one input terminal of the two input terminals of the XOR circuit 665. The other input terminal of the XOR circuit 665 is connected to the power supply and launch control board 321 and is supplied with a + 5V voltage which is an HI level signal. As described above, the output terminal of the XOR circuit 665 is connected to the D2 terminal of the second D flip-flop 663.

  Thus, the pulse signal output from the Schmitt trigger 413 is modulated by the modulation circuit 662 and input to the CLK1 terminal of the first D flip-flop 661. The modulated pulse signal is called a modulated pulse signal.

  The operation of the modulation circuit 662 and the NAND circuit 612 associated therewith will be described based on the timing chart of FIG.

  When the pachinko machine 10 is turned on at timing t32, a reset signal is output from the reset circuit 601. More specifically, the reset circuit 601 outputs a HI level signal. Then, a HI level reset signal is input to the D1 terminal of the first D flip-flop 661. On the other hand, a + 5V voltage is generated from the power-on power supply unit 321a of the power supply and launch control board 321, and the + 5V voltage, that is, the HI level signal is input to the XOR circuit 665. In addition, at the timing, since the rise of the pulse signal does not occur, the signals output from the Q2 terminal and the Q3 terminal do not change.

  When the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t33, the second D flip-flop 663 and the third D flip-flop 664 output signals according to the input state in synchronization with the rise. . Specifically, a HI level signal is input from the power supply and launch control board 321 to one end of the input terminal of the XOR circuit 665 connected to the D2 terminal. Since the LOW level signal is output from the Q2 terminal of the third D flip-flop 664, the LOW level signal is input to the other end of the input terminal of the XOR circuit 665. Therefore, the HI level signal is output from the XOR circuit 665, and the HI level signal is input to the D2 terminal of the second D flip-flop 663. Therefore, the HI level signal is output from the Q2 terminal. On the other hand, since the LOW level signal is output to the D3 terminal of the third D flip-flop 664 at the timing of t33, the LOW level signal is output from the Q3 terminal. The output states of the second D flip-flop 663 and the third D flip-flop 664 are held until the next rise of the pulse signal.

  When the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing t34, the second D flip-flop 663 and the third D flip-flop 664 output signals according to the input state in synchronization with the rise. To do. Since the signal output from the XOR circuit 665 does not change, the second D flip-flop 663 outputs an HI level signal. Further, since the HI level signal is input from the Q2 terminal to the D3 terminal, the signal output from the Q3 terminal of the third D flip-flop 664 rises from the LOW level to the HI level. In synchronization with the rise, the first D flip-flop 661 outputs a HI level signal from the Q1 terminal in response to the reset signal that is the HI level input to the D1 terminal. Then, a LOW level signal is output from the NAND circuit 612 to the MPU 311, and the MPU 311 starts operating when the signal is input.

  In other words, the start of the operation of the MPU 311 is delayed by the delay period DT8 from the timing t32 when the pachinko machine 10 is turned on to the timing t34 when the rising edge of the pulse signal is input to the first D flip-flop 661. . Here, the delay period DT8 is a period in which the period of the pulse signal is added to the period from the timing when the pachinko machine 10 is turned on until the first pulse signal rises. The delay period DT8 is different from the delay period DT6 in the eighth embodiment in that the period of the pulse signal is added to the period from the output of the reset signal to the rise of the first pulse signal. That is, the synchronization timing by the modulated pulse signal and the synchronization timing by the pulse signal differ from each other by one cycle of the pulse signal.

  When the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing t35, the second D flip-flop 663 and the third D flip-flop 664 output signals according to the input state in synchronization with the rise. To do. Specifically, since the HI level signal is output from the Q2 terminal, the HI level signal is input to the two input terminals of the XOR circuit 665. Therefore, a LOW level signal is output from the XOR circuit 665. Therefore, the signal output from the Q terminal of the second D flip-flop 663 is switched from the HI level to the LOW level. Further, since the HI level signal is input from the Q2 terminal to the D3 terminal, the signal output from the Q3 terminal of the third D flip-flop 664 is at the HI level. Therefore, since the rising edge of the signal is not input to the CLK1 terminal of the first D flip-flop 661, the first D flip-flop 661 maintains the output state.

  After that, when the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t36, two HI level signals are input to the XOR circuit 665, and the LOW level signal is output. Therefore, the second D flip-flop 663 outputs a LOW level signal. Further, since the LOW level signal is output from the Q2 terminal, the output signal from the Q3 terminal of the third D flip-flop 664 falls from the HI level to the LOW level. Since the first D flip-flop 661 is not synchronized with the falling edge, the output state from the Q1 terminal is maintained.

  When the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t37, the HI level signal and the LOW level signal are input to the XOR circuit 665 similarly to the timing of the t33, and the HI level. Since the signal is output, the second D flip-flop 663 outputs the HI level signal from the Q2 terminal. Since the LOW level signal is output from the Q2 terminal, the third D flip-flop 664 outputs the LOW level signal from the Q3 terminal. Since the first D flip-flop 661 is not synchronized, the output state from the Q1 terminal is maintained.

  That is, the period T4 from the timing t33 to the timing t37 is a period of the pulse signal output from the second D flip-flop 663 and the third D flip-flop 664, that is, a period of the modulation pulse signal. This period is four times the period T3 of the pulse signal. The pulse width of the modulated pulse signal is also four times the pulse width of the pulse signal. As a result, after the pachinko machine 10 is turned on, the output signal from the Q3 terminal does not rise at the timing t33, which is the first rise timing of the pulse signal, and the Q3 terminal at the next rise timing of the pulse signal. The output signal from will rise.

  When the pachinko machine 10 is turned off at the timing t38, the LOW level signal is immediately input from the signal line LN3 to the NAND circuit 612, and the HI level signal is output to the MPU 311. Fall down immediately. Also, the + 5V voltage supply of the power-on power supply unit 321a is stopped, and the first D flip-flop 661, the second D flip-flop 663, and the second D-flip-flop 663 driven by receiving power supply from the power-on power supply unit 321a The 3D flip-flop 664 stops operating. In such a case, the output state of each D flip-flop 661, 663, 664 is not maintained.

  After that, when the pachinko machine 10 is turned on again at the timing of t39, the reset signal rises similarly to the timing of t32, and accordingly, the reset signal at the HI level is input to the D1 terminal of the first D flip-flop 661. The Thereafter, the operation of the MPU 311 is started at the timing of t40. That is, the operation start timing of the MPU 311 is delayed with respect to the output timing of the reset signal from the reset circuit 601 by the delay period DT9 from the timing t39 to the timing t40.

  According to the embodiment described above in detail, the modulation circuit 662 that modulates the period of the pulse signal is provided, and the first D flip-flop 661 is synchronized based on the rising edge of the modulated pulse signal that is the modulated pulse signal. did. As a result, the timing at which the pulse signal rises is different from the timing at which the modulation pulse signal rises, so the timing at which the first D flip-flop 661 is synchronized is different from the timing at which the first D flip-flop 661 is synchronized. Therefore, the output timing of the LOW level signal from the NAND circuit 612 is different from the configuration for outputting based on the pulse signal. Therefore, an illegal act of grasping the start timing of the operation of the MPU 311 from the rising timing of the pulse signal and the output timing of the reset signal can be prevented.

  In particular, since the pulse signal is obtained by converting an AC voltage from a commercial power supply, the period of the pulse signal may be specified. On the other hand, the modulation pulse signal modulated by the modulation circuit 662 rises after the first rise in the pulse signal output from the Schmitt trigger 413 after the reset signal output timing from the reset circuit 601. Synchronize and get up. That is, the first D flip-flop 661 is not synchronized with the first rising edge in the pulse signal output from the Schmitt trigger 413 after the reset signal output timing from the reset circuit 601. Thereby, the LOW level signal is not output from the NAND circuit 612 at the first rising timing in the pulse signal output from the Schmitt trigger 413. Therefore, even if the period from the output of the reset signal to the rise of the first pulse signal is grasped by grasping the output timing of the reset signal and the rise timing of the pulse signal, the first D flip-flop 661 It is difficult to grasp when to synchronize.

  The modulated pulse signal has a configuration in which both the pulse width and the output interval are modulated to a signal different from the pulse signal. However, the present invention is not limited to this, and either the pulse width or the output interval is different from that of the pulse signal. It may be a signal. In short, it suffices to modulate to a signal in which at least one of the pulse width or output interval of the pulse signal is different.

<Tenth Embodiment>
In the present embodiment, the configuration relating to the power supply of the irregular delay circuit 602 is different from that of the ninth embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the ninth embodiment will be mainly described, and description of the same configuration will be basically omitted. In the tenth embodiment, the configuration shown in FIGS. 41 and 42 is used instead of the configuration shown in FIGS. 39 and 40.

  In the ninth embodiment, since the power supply to the second D flip-flop 663 and the third D flip-flop 664 is stopped when the pachinko machine 10 is in a power-off state, the second D flip-flop 663 and the third D flip-flop 664 are stopped. The stored information is erased and the second D flip-flop 663 and the third D flip-flop 664 are configured not to operate. However, in the present embodiment, this is changed to operate even when the pachinko machine 10 is in a power-off state. The configuration is as follows.

  Specifically, a power supply line ELN1 is provided to electrically connect the second D flip-flop 663, the third D flip-flop 664, and the XOR circuit 665 to the power supply unit 321c for power interruption and the firing control board 321. Yes. The second D flip-flop 663, the third D flip-flop 664, and the XOR circuit 665 are supplied with power even in the power-off state of the pachinko machine 10 via the power line ELN1, so that the power-on state and power-off state of the pachinko machine 10 are maintained. Works regardless. As a result, the range of variation in the delay period can be increased compared to the ninth embodiment.

  Note that a capacitor or the like may be separately provided as a charging means instead of the power interruption power supply unit 321c. The power supply line ELN1 is connected to the power interruption monitoring board 302. However, the power supply line ELN1 is not limited to this, and the power supply unit 321c for power interruption may be directly connected to each D flip-flop. In short, any configuration may be used as long as operating power is supplied regardless of whether the pachinko machine 10 is turned on or off. However, the use of the power interruption power supply unit 321c is superior from the viewpoint of simplification of the configuration.

  The operation of the modulation circuit 662 will be described with reference to FIG. Since the operations of the D flip-flops 661, 663, and 664 are the same as described above, their descriptions are omitted.

  When the pachinko machine 10 enters the power-on state at the timing t41, a reset signal is output from the reset circuit 601 as in the timing t32. At this timing, since the rise of the pulse signal has not occurred, the output states of the second D flip-flop 663 and the third D flip-flop 664 are maintained.

  When the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t42, the signal output from the Q3 terminal of the third D flip-flop 664 starts from the LOW level as in the case of the timing of t34. Since the signal rises to the HI level, the HI level signal is output from the Q1 terminal. That is, the start timing of the operation of the MPU 311 is delayed after the pachinko machine 10 enters the power-on state for the delay period DT10 from the timing t41 to the timing t42. The delay period DT10 is a period obtained by adding the period of the pulse signal by one period to the period from the reset signal output timing to the rising timing.

  When the pachinko machine 10 is turned off at the timing t43, the reset signal is not immediately output and the output signal from the NAND circuit 612 is immediately switched from the LOW level to the HI level. As a result, the MPU 311 immediately executes a predetermined stop process. On the other hand, since power is supplied to the D flip-flops 663 and 664 and the XOR circuit 665 even in the power interruption state, the output states of the D flip-flops 663 and 664 and the XOR circuit 665 are maintained. It should be noted that since no power is supplied to the first D flip-flop 661 in the power-off state, the output state is not maintained.

  Thereafter, when the pachinko machine 10 is turned on again at the timing of t44, the HI level signal is output from the Q2 terminal and the Q3 terminal. Then, the operation start timing of the MPU 311 is delayed with respect to the timing at which the pachinko machine 10 is turned on for the delay period DT11 until the timing t45 when the output from the Q3 terminal switches from the LOW level to the HI level. The delay period DT11 is a period obtained by adding the period of the pulse signal by two periods to the period from the reset signal output timing to the rising timing.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A modulation circuit 662 for modulating the pulse signal output from the Schmitt trigger 413 into a modulation pulse signal having a longer period than the period of the pulse signal, and a configuration in which the first D flip-flop 661 is synchronized based on the modulation pulse signal; did. The D flip-flops 663 and 664 of the modulation circuit 662 operate regardless of the power-on state and power-off state of the pachinko machine 10. As a result, the output state of each D flip-flop 663, 664 varies with respect to the timing at which the reset signal is output from the reset circuit 601, that is, the timing at which the pachinko machine 10 enters the power-on state. Corresponds to the rising period of the modulated pulse signal.

  That is, when each D flip-flop 663, 664 does not operate in the power-off state, each D flip-flop 663, 664 outputs a predetermined state, that is, a LOW level signal after the pachinko machine 10 is turned on. Start operation from state. In such a case, the delay period from the output of the reset signal to the start of the operation of the MPU 311 is obtained by adding one period of the pulse signal to the period from when the reset signal is output until the first pulse signal rises. . That is, since the D flip-flops 663 and 664 start operation from a predetermined state with respect to the timing when the pachinko machine 10 is turned on, the period from when the reset signal is output until the first pulse signal rises The period of the pulse signal added to is constant. Then, the period that varies according to the output timing of the reset signal is a period from when the reset signal is output until the first pulse signal rises, and the entire delay period is a predetermined pulse with respect to the varying period. The period is offset by one period of the signal. In other words, the range of variation in the delay period corresponds to the period of the pulse signal.

  On the other hand, when each D flip-flop 663, 664 is operating regardless of the power-on state and power-off state of the pachinko machine 10, each D flip-flop with respect to the timing at which the pachinko machine 10 enters the power-on state. The output states of 663 and 664 are fluctuating. That is, the output state of the signal output from the Q3 terminal does not depend on the timing when the pachinko machine 10 enters the power-on state. In other words, the range of variation in the delay period corresponds to the period of the signal output from the Q3 terminal. Since the period of the signal is longer than the period of the pulse signal, the variation range of the delay period is wide as compared with a configuration that does not operate in the power interruption state. Therefore, the delay period is more irregular because the delay period varies greatly. Therefore, since it is difficult to grasp the update start timing of the jackpot random number counter C1, it is difficult to grasp the timing of winning the jackpot. Therefore, an illegal act using a “hanging board” or the like can be prevented.

  The D flip-flops 663 and 664 are configured to operate regardless of the power-on state and the power-off state of the pachinko machine 10, but the present invention is not limited to this, and information on each D flip-flop 663 and 664 is held. The effects described above can also be obtained as a configuration. Specifically, the pulse signal output from the Schmitt trigger 413 may be blocked. With this configuration, power consumption can be suppressed.

  In addition, the modulated pulse signal has a configuration in which both the pulse width and the output interval are larger than the pulse width and the output interval of the pulse signal. However, the present invention is not limited to this, and either the pulse width or the output interval is increased. It is good. In short, at least one of the pulse width and output interval of the modulated pulse signal may be made larger than that of the pulse signal.

<Eleventh embodiment>
In the present embodiment, the configuration relating to the modulation circuit in the irregular delay circuit 602 is different from that in the tenth embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the tenth embodiment will be mainly described, and description of the same configuration will be basically omitted. In the eleventh embodiment, the configuration shown in FIGS. 43 and 44 is used instead of the configuration shown in FIGS. 41 and 42.

  In this embodiment, the pulse signal output from the Schmitt trigger 413 is modulated into a signal having two different output intervals and alternately output at two output intervals. The first D flip-flop 661 outputs a signal corresponding to the input state based on the rising edge of the modulated signal.

  Specifically, the irregular delay circuit 602 includes a modulation circuit 671 that modulates the pulse signal so that signals with different rising intervals of the pulse signal are output instead of the modulation circuit 662. Similarly to the modulation circuit 314 in the first embodiment, the modulation circuit 671 includes a fourth D flip-flop 672, a fifth D flip-flop 673, a sixth D flip-flop 674, a first XOR circuit 675, and a second XOR circuit 676. ,have. These are electrically connected to the power supply and power supply unit 321a of the power supply and launch control board 321 via an unillustrated electrical path and a power interruption monitoring board 302, and the pachinko machine 10 is in a power-on state. The operating power is supplied from the power-on power supply unit 321a. The D flip-flops 672, 673, and 674 and the XOR circuits 675 and 676 are electrically connected to the power supply unit 321c for power interruption through the power supply line ELN2. When the pachinko machine 10 is in a power-off state, operating power is supplied from the power-off power supply unit 321c. That is, each D flip-flop 672, 673, 674 and each XOR circuit 675, 676 operate regardless of the power-on state and power-off state of the pachinko machine 10.

  In addition, it is good also as a structure which replaces with the power supply part 321c at the time of a power failure, and provides charging means, such as a capacitor | condenser separately. The power supply line ELN2 is connected to the power interruption monitoring board 302. However, the power supply line ELN2 is not limited to this, and the power supply unit 321c for power interruption may be directly connected to each D flip-flop. In short, any configuration may be used as long as operating power is supplied regardless of whether the pachinko machine 10 is turned on or off. However, the use of the power interruption power supply unit 321c is superior from the viewpoint of simplification of the configuration.

  Since the connections of the D flip-flops 672, 673, and 674 and the XOR circuits 675 and 676 are the same as those of the modulation circuit 314 in the first embodiment, the description thereof is omitted.

  The operation of the modulation circuit 671 will be described based on the timing chart of FIG. At the timings t46, t48, t49, t50, 52, t53, t55, t56, and t57, the D flip-flops 672, 673, and 674 synchronously output the signals input to the D terminals from the Q terminal. . Since the outputs from the Q4 terminal to the Q6 terminal at these timings are the same as the outputs from the Q1 terminal to the Q3 terminal in the first embodiment (FIG. 22), detailed description is omitted, but the modulation circuit 671 A pulse signal having a different pulse width and output interval is repeatedly output with a period T5 from the timing t46 to the timing t56 as one cycle.

  When the power of the pachinko machine 10 is ON at the timing t47, that is, when the pachinko machine 10 is turned on, a reset signal is output from the reset circuit 601. More specifically, the reset circuit 601 outputs a HI level signal. Then, a HI level reset signal is input to the D1 terminal of the first D flip-flop 661.

  After that, when the signal output from the Schmitt trigger 413 rises from the LOW level to the HI level at the timing of t49, the signal output from the Q6 terminal rises from the LOW level to the HI level. In synchronization with the rise, the HI level signal is output from the Q1 terminal. Then, since two HI level signals are input to the NAND circuit 612, a LOW level signal is output from the NAND circuit 612. The MPU 311 starts operation by inputting the signal. That is, the operation start timing of the MPU 311 is delayed with respect to the output timing of the reset signal by the delay period DT12 from the timing t47 to the timing t49.

  When the pachinko machine 10 is turned off at the timing t51, the reset signal is not immediately output and the output signal from the NAND circuit 612 is immediately switched from the LOW level to the HI level. On the other hand, since power is supplied to the D flip-flops 672, 673, and 674 even in the power-off state, the output states of the D flip-flops 672, 673, and 674 are maintained. Note that the first D flip-flop 661 is not maintained in the output state because no operating power is supplied when the pachinko machine 10 is in a power-off state.

  When the pachinko machine 10 is turned on again at the timing t54, a reset signal at the HI level is output from the reset circuit 601. Since this timing is not the rising timing of the pulse signal input to each CLK terminal of each D flip-flop 672, 673, 674, each D flip-flop 672, 673, 674 holds the output state.

  Thereafter, since the signal output from the Q6 terminal rises from the LOW level to the HI level at the timing of t57, the HI level signal is output from the first D flip-flop 661 to the NAND circuit 612 in synchronization with the rise. As a result, a LOW level signal is output from the NAND circuit 612. That is, the output timing of the LOW level signal from the NAND circuit 612 is delayed with respect to the output timing of the reset signal from the reset circuit 601 by the delay period DT13 from the timing t54 to the timing t57.

  Here, the period Tc from the timing t49 which is the rising interval of the signal output from the Q6 terminal to the timing t53 is different from the period Td from the timing t53 to the timing t57 which is the next rising timing. ing. Specifically, the period Tc is three times the period T3 of the pulse signal, and the period Td is four times the period T3 of the pulse signal. That is, pulse signals are alternately output from the Q6 terminal at two types of output intervals.

  In the present embodiment described in detail above, pulse signals are alternately output from the Q6 terminal of the sixth D flip-flop 674 at two types of output intervals. Based on the rising edge of the pulse signal, the first D flip-flop 661 is synchronized. Therefore, there are two types of timing intervals at which the first D flip-flop 661 is synchronized. This makes it difficult to grasp the timing at which the first D flip-flop 661 is synchronized.

  In the present embodiment, the rising intervals of the pulse signal are two types of the period Tc and the period Td, but are not limited to this, and may be three or more types. The point is that the HI level signal may be output at least at two kinds of output intervals.

  In this embodiment, the signal output from the modulation circuit 671 is a signal in which the HI level signal is output at least at two types of output intervals. However, the present invention is not limited to this, and at least two types of pulse width signals are output. It may be an output signal. Even in such a configuration, two kinds of rising intervals of the pulse signal can be provided. In short, the modulation circuit 671 only needs to be a circuit that generates at least one of a signal in which an HI level signal is output with at least two types of output intervals or a signal with at least two types of pulse widths. The configuration is arbitrary.

  Further, the composite pulse signal used in the present embodiment may be applied to the seventh embodiment. In the signal output from the Q6 terminal, there are two kinds of LOW level periods and two kinds of HI level periods. Therefore, in the seventh embodiment, the same effect as described above can be obtained.

<Twelfth Embodiment>
Hereinafter, a twelfth embodiment of the pachinko machine 10 in which a jackpot lottery is performed using the jackpot random number counter C1 will be described with reference to FIGS. 45 and 46. FIG. 45 is a diagram showing an electrical configuration of the pachinko machine 10 in the present embodiment, and FIG. 46 is a flowchart showing a main process. In the following description, differences from the above embodiments will be described, and the description of the same configuration will be basically omitted.

  In this embodiment, instead of the configuration in which the MPU 311 is provided with the counters CINI and C1, a counter update circuit 701 having an initial value random number counter CF and a big hit random number counter C1 is separated from the MPU 311 as shown in FIG. The body is provided on the main control board 301. The counter update circuit 701 is electrically connected to the power supply and launch control board 321 via the power interruption monitoring board 302. The counter update circuit 701 includes a power-on power supply section 321a or a power-off power supply section 321c. The power is always supplied from.

  The counter update circuit 701 includes a circuit that outputs a pulse signal at a predetermined cycle. The jackpot random number counter C1 and the initial value random number counter CF are 0 to 676 in synchronization with the pulse signal output from the circuit. Within the range, 1 is added in order, and after reaching the maximum value (ie, 676), it returns to 0. That is, independently of the MPU 311, the values of the jackpot random number counter C <b> 1 and the initial value random number counter CF are updated, and are updated regardless of the power-on state and the power-off state of the pachinko machine 10.

  Here, the counter update circuit 701 is separately provided with a pulse signal input count counter. Regarding the initial value random number counter CF, when the input count counter reaches a predetermined value (for example, “5”). In addition, the numerical value of the initial value random number counter CF is updated. As a result, the update frequency of the initial value random number counter CF and the update frequency of the jackpot random number counter C1 are different. Therefore, the initial value random number counter CF and the big hit random number counter C1 are not completely synchronized.

  Further, the counter update circuit 701 is separately provided with a counter that determines the initial value of the input number counter. The counter is independently updated in a numerical range that can be taken by the input number counter (for example, within a range of “0” to “4”), and when the value of the initial value random number counter CF is updated, The value of the input number counter at the time is acquired. As a result, the value of the initial value random number counter CF is updated at irregular timings. Therefore, it is difficult to grasp the value of the initial value random number counter CF.

  Next, main processing in this embodiment will be described with reference to FIG. The processes in steps S901 to S909 and the processes in steps S911 to S913 in the main process are the same as the processes in steps S401 to S409 and the processes in steps S410 to S412 in the main process of FIG. Here, the clear target in the clear process of the used RAM area is the RAM 316 of the MPU 311, and the counter value of the counter update circuit 701 is excluded from the clear process target.

  In the present embodiment, before the process of setting interrupt permission in step S911 (after executing the initial setting of the RAM 316 in step S909 or after executing the process of deleting the RAM determination value in step S913), the initial setting is performed in step S910. The point which performs a value setting process is different from other embodiment. In the initial value setting process, the MPU 311 acquires the value of the initial value random number counter CF at that time, and the acquired value is set as the initial value of the jackpot random number counter C1. The value of the jackpot random number counter C1 is sequentially updated from the value of the initial value random number counter CF in the counter update circuit 701.

  That is, regardless of whether the pachinko machine 10 is turned off or on, the values of the jackpot random number counter C1 and the initial value random number counter CF are updated independently from the MPU 311 and the pachinko machine 10 is turned on. In this case, the value of the initial value random number counter CF is acquired by the MPU 311 and the value of the jackpot random number counter C1 is updated using the acquired value as an initial value.

  Further, as in the above embodiments, an irregular delay circuit 602 is provided on the path connecting the reset circuit 601 and the MPU 311, and the irregular delay circuit 602 allows the output timing of the reset signal to be adjusted. The start timing of the operation of the MPU 311 is irregularly delayed. The reset signal is a signal that is output when the pachinko machine 10 is powered on. The initial value setting process is a process executed when the MPU 311 starts its operation. Therefore, the execution timing of the initial value setting process is irregularly delayed with respect to the timing when the power to the pachinko machine 10 is turned on. That is, in this embodiment, the target of the process delayed by the irregular delay circuit 602 is the initial value setting process, and the execution of the process is delayed so that the timing at which the pachinko machine 10 is turned on is delayed. The initial value acquisition timing is delayed.

  In a situation where the pachinko machine 10 is in the power-on state, when the value of the big hit random number counter C1 makes one round, a notification signal that notifies that is output to the MPU 311. The RAM 316 has a flag storage area corresponding to the notification signal. When the notification signal is input to the MPU 311, a flag corresponding to the notification signal is stored in the storage area. Yes. Then, after the process of step S508 of the normal process (see FIG. 20), a process for determining whether or not a flag corresponding to the signal is stored is executed. When the corresponding flag is stored, the MPU 311 reads the value of the initial value random number counter CF at that time and sets the value as the initial value of the jackpot random number counter C1. Thereafter, the value of the jackpot random number counter C1 is updated from the initial value. Thus, the initial value random number counter CF is also used as the random number initial value counter CINI.

  As for the start winning process, as shown in the flowchart of FIG. 18, in step S305, the MPU 311 reads the value of the jackpot random number counter C1 at that time from the counter update circuit 701, and the read value is sent to step S307. To store in the holding ball storage area.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A counter update circuit 701 having a jackpot random number counter C1 and an initial value random number counter CF that are periodically updated regardless of the power-on state and power-off state of the pachinko machine 10 is provided. When the MPU 311 is operating, and when a game ball enters the operation port 84, the MPU 311 reads the jackpot random number counter C1 at that time. In such a configuration, in the main process executed when the MPU 311 starts operation, the value of the initial value random number counter CF at that time is set as the initial value of the jackpot random number counter C1, and the value of the jackpot random number counter C1 is set. It was set as the structure updated sequentially from the made initial value. Here, since the value of the initial value random number counter CF is updated regardless of the power-on state and power-off state of the pachinko machine 10, the value of the initial value random number counter CF depends on the timing at which the MPU 311 starts operation. Have fluctuated. As a result, the initial value of the jackpot random number counter C1 when the MPU 311 starts operation becomes irregular, so that the initial value is difficult to grasp. Therefore, it is difficult to grasp the timing at which the value of the jackpot random number counter C1 becomes the winning value based on the start timing of the operation of the MPU 311. Therefore, fraudulent acts using a “hanging board” or the like can be suppressed.

  The initial value random number counter CF and the jackpot random number counter C1 are not completely synchronized. If the two are completely synchronized, even if the initial value random number counter CF is acquired as the initial value of the jackpot random number counter C1, the acquired value is the value of the jackpot random number counter C1 at that time. By grasping the value of the jackpot random number counter C1, the initial value of the jackpot random number counter C1 after the execution of the initial value acquisition process can be grasped, and an illegal act using a “hanging board” or the like by the execution of the initial value acquisition process It is not possible to obtain a sufficient suppression effect. On the other hand, if the jackpot random number counter C1 and the initial value random number counter CF are not completely synchronized, the value of the initial value random number counter CF is difficult to grasp from the jackpot random number counter C1. It is possible to suitably suppress fraud using “

  Further, since the value of the initial value random number counter CF is updated regardless of the power-on state and the power-off state of the pachinko machine 10, the value of the initial value random number counter CF is constantly changing. Thereby, when the pachinko machine 10 is in a power-off state, the value of the initial value random number counter CF is less likely to be grasped than the configuration in which the value of the initial value random number counter CF is held. Therefore, it is possible to more appropriately suppress an illegal act using a “hanging board” or the like.

  The counter value of the counter update circuit 701 is excluded from the initialization target. If the counter values of the counter update circuit 701 are to be initialized, these values are set to predetermined values by the RAM data initialization process, and are acquired after the initialization process. The value of the initial value random number counter CF does not change. On the other hand, since the counter value of the counter update circuit 701 is excluded from the initialization target of the initialization process of the RAM data as in the above configuration, the counter value is affected by the initialization process of the RAM data. I do not receive it. As a result, the value of the initial value random number counter CF acquired after the initialization process varies according to the acquisition timing. That is, the fluctuation of the initial value after the initialization process is secured.

  Here, if the output timing of the reset signal is grasped by “hanging board” or the like, and further the value of the random number counter CF for initial value is grasped, the value of the random number counter CF for initial value at the output timing of the reset signal is grasped. There is a risk of being. Then, since the initial value of the jackpot random number counter C1 at the output timing of the reset signal is grasped, there is a possibility that the timing at which the value of the jackpot random number counter C1 becomes the winning value may be grasped. On the other hand, since the irregular delay circuit 602 is provided on the path connecting the reset circuit 601 that outputs the reset signal and the MPU 311 that executes the initial value setting process, the output timing of the reset signal is The operation start timing of the MPU 311 is irregularly delayed. As a result, the execution timing of the initial value setting process is irregularly delayed with respect to the reset signal output timing, so that the initial value random number counter CF acquisition timing is irregular with respect to the reset signal output timing. Therefore, it is difficult to grasp the initial value of the jackpot random number counter C1 based on the output timing of the reset signal. Accordingly, it is possible to make it difficult to grasp the timing at which the value of the jackpot random number counter C1 becomes the winning value, and therefore it is possible to suitably suppress fraud using the “hanging board” or the like.

  In the present embodiment, any of the irregular delay circuits 602 of the fifth to eleventh embodiments may be used.

  Further, although the counter update circuit 701 is provided on the main control board 301, it is not limited thereto. However, it is preferable to provide the main control board 301 from the viewpoint of security and wiring.

<13th Embodiment>
In the present embodiment, the object to be delayed by the irregular delay circuit 602 is different. Therefore, the object to be delayed in this embodiment will be described below. In the following description, the description of the same configuration as that of the fifth to twelfth embodiments is basically omitted.

  As shown in FIG. 47, the power supply and launch control device 243 is provided with a power-on RAM erase switch 801 instead of the RAM erase switch 247. The RAM erasing switch 801 during power-on is a switch that can be pressed from the outside. The power-on RAM erase switch 801 is electrically connected to a RAM erase signal output circuit 802 provided on the main control board 301.

  The RAM erase signal output circuit 802 is electrically connected to the MPU 311. The RAM erase signal output circuit 802 is configured to output a RAM erase signal based on the operation of the RAM erase switch 801 during power-on. When the RAM erase signal is input to the MPU 311, the MPU 311 is configured to execute the process of initializing the RAM data, specifically the process of step S 408 and step S 409 of the main process (FIG. 19). Yes. As a result, the RAM data initialization process can be performed without the power ON / OFF operation. That is, in each of the embodiments described above, the process of initializing the RAM data is performed by turning on the power while pressing the RAM erase switch 247. However, in this embodiment, the RAM data is not required to be turned on. The initialization process can be performed. Thereby, the initialization process of RAM data can be performed easily.

  Here, as shown in FIGS. 47 and 48, an irregular delay circuit 602 is provided on a path connecting the RAM erase signal output circuit 802 and the MPU 311. The RAM erase signal output from the RAM erase signal output circuit 802 is input to the MPU 311 via the irregular delay circuit 602. More specifically, when the RAM erase switch 801 is turned on during operation, a HI level signal that is a RAM erase signal is output from the RAM erase signal output circuit 802. The HI level signal is input to the NAND circuit 612 via the signal line LN3 and the signal line LN4. In this case, the signal state input from the signal line LN3 to the NAND circuit 612 immediately becomes the HI level.

  On the other hand, the input of the HI level signal from the signal line LN 4 to the NAND circuit 612 is delayed by the integration circuit 611 of the irregular delay circuit 602. The delay period varies depending on the residual charge amount accumulated in the capacitor 613 as described above. When a HI level signal is input to the NAND circuit 612 from the signal line LN3 and the signal line LN4, a LOW level signal is output from the NAND circuit 612. When the LOW level signal is input to the MPU 311, the MPU 311 executes processing for initializing RAM data.

  In the present embodiment described above in detail, the irregular delay circuit 602 is provided on the path connecting the RAM erase signal output circuit 802 and the MPU 311. As a result, the period from the output timing of the RAM erase signal output from the RAM erase signal output circuit 802 to the execution timing at which the RAM data initialization process is executed varies. Therefore, the period becomes irregular. Accordingly, even when the RAM data initialization process is executed, even if the value of the jackpot random number counter C1 is updated from a predetermined fixed value, the RAM erase signal output circuit 802 Based on the timing at which the RAM erase signal is output (or the timing at which the power-on RAM erase switch 801 is operated), it is difficult to grasp the timing at which the value of the jackpot random number counter C1 becomes the winning value. Therefore, it is possible to suppress an illegal act using the “hanging board” or the like while ensuring the ease of the initialization process of the RAM data.

  Note that the power-on RAM erasing switch 801 is provided in the power supply and launch control device 243, but is not limited thereto, and may be provided in the main control device 162, for example.

  In this embodiment, the configuration of the fifth embodiment is used as the irregular delay circuit 602. However, the configuration is not limited to this, and any configuration of the sixth to eleventh embodiments may be used.

<Fourteenth embodiment>
In the present embodiment, the configuration related to the jackpot random number counter C1 and the like is different from that in the thirteenth embodiment. Therefore, the different points will be described in detail. In the following description, the description of the same configuration as that of the thirteenth embodiment is basically omitted.

  In this embodiment, the counter update circuit 701 shown in the twelfth embodiment is provided. As described above, the counter update circuit 701 is provided with the jackpot random number counter C1 and the initial value random number counter CF, and the values of the counters C1 and CF are independent of the power-on state and the power-off state of the pachinko machine 10. , And updated independently of the MPU 311. When a game ball enters the operation port 84, the MPU 311 reads the value of the jackpot random number counter C1 at that time and determines whether or not the value matches the winning value.

  A normal process in such a configuration will be described with reference to FIG. First, in step S1001, it is determined whether there is a RAM erase flag. Here, the RAM 316 is provided with a RAM erasure flag storage area. When a RAM erasure signal is input to the MPU 311, the RAM erasure flag is stored in the RAM erasure flag storage area by timer interrupt processing (FIG. 17). Flag to be That is, the fact that the RAM erase flag is stored means that the power-on RAM erase switch 801 has been operated. In this case, the process proceeds to step S1002.

  The processes in steps S1002 to S1004 are the same as the processes in steps S908 to S910. That is, the used RAM area is cleared and the RAM 316 is initialized. Then, the value of the initial value random number counter CF is acquired, and the acquired value is set as the initial value of the jackpot random number counter C1.

  Thereafter, in step S1005, a RAM erase flag clear process is executed. In this process, the RAM erase flag is erased. After executing this process, the process proceeds to step S1006.

  The processing from step S1006 to step S1012 is the same as the processing from step S501 to step S507 in FIG.

  In the processing of step S1013 and step S1014, the initial value setting processing of the jackpot random number counter C1 when the value of the jackpot random number counter C1 makes one round is executed. Specifically, first, in step S1013, it is determined whether or not the value of the jackpot random number counter C1 has made one round. Specifically, when the value of the jackpot random number counter C1 makes one round, a signal to that effect is output from the counter update circuit 701. The RAM 316 is provided with a flag storage area corresponding to the signal, and when the signal is input to the MPU 311, a flag corresponding to the signal is stored in the storage area. In step S1013, it is determined whether or not the corresponding flag is stored.

  If the value of the jackpot random number counter C1 does not make one round, the process proceeds to step S1015. If the value of the jackpot random number counter C1 makes one round, the process proceeds to step S1014, and an initial value setting process is executed. The process proceeds to step S1015. The initial value setting process is the same as step SS1004 (step S910). The processing in steps S1015 to S1018 is the same as the processing in steps S508 to S511.

  According to the embodiment described in detail above, the pachinko machine 10 provided with the power-on RAM erasure switch 801 and the RAM erasure signal output circuit 802 has the counter update having the big hit random number counter C1 and the initial value random number counter CF. A circuit 701 is provided. When the on-charge RAM erasure switch 801 is operated, the RAM data initialization process is executed, the value of the initial value random number counter CF of the counter update circuit 701 is acquired, and the acquired value Is set as the initial value of the jackpot random number counter C1. As a result, when the power-on RAM erasure switch 801 is operated, the value of the initial value random number counter CF obtained by the initial value setting process varies depending on the operation timing of the power-on RAM erasure switch 801. The initial value of the jackpot random number counter C1 is difficult to grasp when the RAM erase switch 801 is turned on during operation. Therefore, fraudulent acts such as “hanging board” can be suppressed.

  Further, the value of the jackpot random number counter C1 and the value of the initial value random number counter CF are independently updated in the counter update circuit 701, and the MPU 311 only reads the updated numerical value. It has been reduced. In particular, there is a concern about an increase in processing load when the RAM erasing switch 801 that is turned on is provided and the initialization process of the RAM data based on the RAM erasing switch 801 that is turned on is executed in the normal process. Then, the random number initial value update process is not sufficiently performed, and the numerical value of the random number initial value counter CINI may be biased. Then, the numerical value that the big hit random number counter C1 can take is also biased. On the other hand, in this embodiment, since the value of the jackpot random number counter C1 and the value of the initial value random number counter CF are updated regardless of the processing status of the MPU 311, the inconvenience is avoided. That is, it is possible to avoid problems that may occur due to the provision of the RAM erasing switch 801 during power-on and RAM data initialization processing based thereon.

<Fifteenth embodiment>
Hereinafter, a fifteenth embodiment of the pachinko machine 10 in which a jackpot lottery is performed using the jackpot random number counter C1 will be described with reference to FIGS. 50 and 51. FIG. 50 is a diagram illustrating a part of the electrical configuration of the pachinko machine 10 according to the present embodiment. In the following description, differences from the above embodiments will be described, and the description of the same configuration will be basically omitted.

  In the first embodiment and the like, the hard random number clock circuit 313 generates a clock signal from an AC voltage. However, in this embodiment, instead of this, a crystal resonator is provided and operating power is supplied. The jackpot random number counter C1 is updated using a hard random number clock circuit 900 that generates a hard random number clock signal based on the above.

  Specifically, the main control board 301 is provided with a hard random number clock circuit 900 that outputs a hard random number clock signal. The hard random number clock circuit 900 is an oscillation circuit including a crystal resonator, and is electrically connected to the power supply and launch control board 321 via the power interruption monitoring board 302. When the pachinko machine 10 is turned on, a DC voltage operating voltage Vcc is supplied as operating power from the power source and launch control board 321 to the hard random number clock circuit 900. The hard random number clock circuit 900 is configured to output a hard random number clock signal in a situation where operating power is supplied from the power supply and launch control board 321. The hard random number clock signal is set to be a clock signal having a period different from that of the system clock signal.

  The hard random number clock circuit 900 is electrically connected to the MPU 311, and the hard random number clock signal is output to the MPU 311. A jackpot random number counter C1 that updates numerical information based on the input of a hard random number clock signal is provided in a part of the ROM 315 of the MPU 311. The jackpot random number counter C1 is set to be updated in synchronization with the input of the hard random number clock signal without being synchronized with the input of the system clock signal. The jackpot random number counter C1 is configured so that it is incremented one by one within the range of 0 to 676, reaches a maximum value (that is, 676), and then returns to 0. Then, when a game ball enters the operation port 84, the value of the big hit random number counter C1 at that time is acquired, and determination of success or failure is performed.

  It should be noted that when the pachinko machine 10 is cut off, the counter value of the jackpot random number counter C1 is not held. In the start-up process that is executed when the pachinko machine 10 is turned on, the counter value of the jackpot random number counter C1 is reset to a predetermined value (for example, “0”).

  Here, as shown in FIGS. 50 and 51, a power transmission circuit 901 that transmits operating power is provided on a path connecting the hard random number clock circuit 900 and the power interruption monitoring board 302. The power transmission circuit 901 will be described with reference to the block circuit diagram of FIG.

  The power transfer circuit 901 uses the random delay circuit 602, the adjustment resistor 911 that adjusts the voltage and current for the irregular delay circuit 602, and the signal output from the irregular delay circuit 602 for operating power for hard random numbers. And an amplifier circuit 912 that supplies the clock circuit 900.

  First, the amplifier circuit 912 will be described. The amplifier circuit 912 includes an NPN transistor 913 and a PNP transistor 914. These two transistors 913 and 914 are so-called inverted Darlington connection. Specifically, the collector of the NPN transistor 913 and the base of the PNP transistor 914 are connected, the emitter of the NPN transistor 913 is grounded, and the base of the NPN transistor 913 is connected to the output terminal of the irregular delay circuit 602. The collector of the PNP transistor 914 is connected to the hard random number clock circuit 900, and the emitter of the PNP transistor 914 is connected to the power supply and launch control board 321. A DC operating voltage Vcc is applied to the emitter of the PNP transistor 914 from the power supply and launch control board 321 when the pachinko machine 10 is in the power-on state.

  According to such a configuration, in a situation where a LOW level signal is output from the irregular delay circuit 602, no current flows through the base of the NPN transistor 913, and thus the NPN transistor 913 is in an OFF state. In this case, no current flows between the collector and emitter of the NPN transistor 913. Since the current between the collector and emitter of the NPN transistor 913 is the base current of the PNP transistor 914, no current flows through the base of the PNP transistor 914. For this reason, the PNP transistor 914 is off. As a result, no current flows between the collector and emitter of the PNP transistor 914, so that no operating power is supplied to the hard random number clock circuit 900.

  On the other hand, when the HI level signal is output from the irregular delay circuit 602, a base current of a predetermined magnitude flows through the NPN transistor 913, so that the NPN transistor 913 is turned on. In this case, a base current flows with respect to the base of the PNP transistor 914. The current value of the base current is a value obtained by multiplying the current value of the base current flowing through the NPN transistor 913 by the amplification factor of the NPN transistor 913. Then, the PNP transistor 914 is turned on, and a predetermined current (collector current) flows between the emitter and collector of the PNP transistor 914. The collector current is a value obtained by multiplying the current value of the base current of the PNP transistor 914 by the amplification factor of the PNP transistor 914. That is, the current value of the collector current is a value obtained by multiplying the current value of the base current of the NPN transistor 913 by the amplification factor of the NPN transistor 913 and the amplification factor of the PNP transistor 914.

  Further, since the inverted Darlington connection is made between the NPN transistor 913 and the PNP transistor 914, the voltage lost in the amplifier circuit 912 is the saturation voltage (voltage between the collector and the emitter) of the PNP transistor 914.

  For example, in the case of a Darlington connection consisting of two NPN transistors, the amplification factor is the same as in the case of an inverted Darlington connection, but the voltage lost due to its configuration is between the base and emitter of the first stage NPN transistor. This voltage is a sum of the voltage and the saturation voltage of the second stage NPN transistor. That is, when the inverted Darlington connection is used, the voltage loss due to the amplifier circuit 912 is reduced while securing the same amplification factor as compared with the case where the Darlington connection is used.

  From the above, when the HI level signal is output from the irregular delay circuit 602, the hard random number clock circuit 900 is supplied with a higher current than the current flowing from the irregular delay circuit 602, and the high A voltage in which a voltage drop due to currentization is suppressed is applied. As a result, when the HI level signal is output from the irregular delay circuit 602, the hard random number clock circuit 900 is supplied with power capable of operating the hard random number clock circuit 900 while suppressing circuit loss. Can do. That is, the amplification circuit 912 is turned on / off according to the output state from the irregular delay circuit 602, and the power supply to the hard random number clock circuit 900 is turned on / off according to the switching.

  Each of the NPN transistor 913 and the PNP transistor 914 is provided with input resistors 913a and 914a for converting a voltage input to the base into a current. Thereby, the NPN transistor 913 and the PNP transistor 914 are controlled based on the base current instead of the input voltage. Specifically, in general, in a transistor, the collector current changes exponentially with changes in the input voltage with respect to the base, while changing linearly with changes in the base current. For this reason, the control based on the base current can realize a stable supply of collector current than the control based on the input voltage to the base. Therefore, stable operating power can be supplied to the hard random number clock circuit 900.

  Each of the NPN transistor 913 and the PNP transistor 914 is provided with a bypass wiring for connecting the base and the emitter, and resistors 913b and 914b are provided on the wiring. As a result, leakage current (including that generated by noise or the like) flows on the bypass wiring via the resistor 913b or 914b, so that the leakage current hardly flows to the base of the transistor. Therefore, malfunctions of the transistors 913 and 914 are suppressed.

  In particular, in the case of inverted Darlington connection, since the base of the PNP transistor 914 is floating in a situation where the NPN transistor 913 is in an off state, the input voltage to the base tends to become unstable. For this reason, the power supply to the hard random number clock circuit 900 becomes unstable, and the hard random number clock signal may not be output in a predetermined cycle. On the other hand, in this embodiment, the base of the PNP transistor 914 is pulled up by the bypass wiring and the resistor 914b. As a result, the above inconvenience can be avoided, and the stability of the circuit in the amplifier circuit 912 is enhanced. That is, inconveniences that can be caused by using the inverted Darlington connection can be avoided.

  Further, when the output from the irregular delay circuit 602 or the application of the operating voltage Vcc is stopped, the carriers accumulated in the transistors 913 and 914 are discharged through the bypass wiring, so that the turn-off speed can be increased. It has been realized. As a result, the supply of operating power to the hard random number clock circuit 900 can be quickly stopped.

  The irregular delay circuit 602 and the adjustment resistor 911 that perform on / off control of the amplifier circuit 912 will be described.

  First, the adjustment resistor 911 will be described. The adjustment resistor 911 is arranged in series on a path connecting the irregular delay circuit 602 and the power source and the launch control board 321. When the operating voltage Vcc is applied from the power supply and launch control board 321, the operating voltage Vcc is input to the irregular delay circuit 602 through the adjustment resistor 911. As a result, the input voltage and input current input to the irregular delay circuit 602 are adjusted by the resistance value of the adjustment resistor 911. More specifically, when the operating voltage Vcc is applied from the power supply and launch control board 321, the irregular delay circuit 602 is set so that a voltage that can be recognized as an HI level signal is input. Accordingly, since an excessive voltage is applied to the irregular delay circuit 602 and a current is prevented from flowing, normal operation of the irregular delay circuit 602 and reduction in power consumption can be achieved. .

  Next, the irregular delay circuit 602 will be described. The irregular delay circuit 602 is configured to output a HI level signal or a LOW level signal based on the input voltage from the power supply and launch control board 321 and the pulse signal from the signal conversion circuit 402. Specifically, the irregular delay circuit 602 includes a D flip-flop 915 and an AND circuit 916. A power supply and launch control board 321 is connected to the D terminal of the D flip-flop 915 via an adjustment resistor 911, and the output terminal of the signal conversion circuit 402 (the output terminal of the Schmitt trigger 413) is connected to the CLK terminal. One input terminal of the AND circuit 916 is connected to the Q terminal. A power supply and launch control board 321 is connected to the other input terminal of the AND circuit 916 via an adjustment resistor 911.

  Here, the operation of the irregular delay circuit 602 will be described. When the pachinko machine 10 is turned on, the operating voltage Vcc is applied from the power supply and launch control board 321, and the HI level signal is input to the D terminal of the D flip-flop 915 and one end of the input terminal of the AND circuit 916. In this case, a LOW level signal is output from the Q terminal, and a LOW level signal is output from the AND circuit 916.

  Thereafter, as described in the eighth embodiment, when the pulse signal from the Schmitt trigger 413 rises, the HI level signal is output from the Q terminal in synchronization with the rise. Then, since the HI level signal is output from the AND circuit 916, the amplifier circuit 912 operates as described above. When the amplifier circuit 912 operates, operating power is supplied to the hard random number clock circuit 900.

  Here, the period from when the operating voltage Vcc is applied until the AND circuit 916 outputs the HI level signal varies depending on the form of the pulse signal at the time when the operating voltage Vcc is applied. The form of the pulse signal varies depending on the timing at which the pachinko machine 10 is turned on. That is, it can be said that the period from when the pachinko machine 10 is turned on to when the HI level signal is output from the AND circuit 916 varies according to the timing at which the pachinko machine 10 is turned on. As a result, the period from when the pachinko machine 10 is turned on to when the operating power is supplied to the hard random number clock circuit 900 is irregular.

  When the pachinko machine 10 is cut off, application of the operating voltage Vcc from the power supply and launch control board 321 is stopped. In this case, the LOW level signal is input to the irregular delay circuit 602, specifically to the D terminal of the D flip-flop 915 and the other input terminal of the AND circuit 916. As a result, a LOW level signal is immediately output from the AND circuit 916, and the amplifier circuit 912 is turned off. Therefore, the amplifier circuit 912 can be turned off without waiting for the output of the LOW level signal from the Q terminal.

  Here, in a situation where the operating voltage Vcc is not supplied from the power supply and launch control board 321, no voltage is applied between the collector and emitter of the PNP transistor 914 of the amplifier circuit 912, so that the output state of the irregular delay circuit 602 is related. Therefore, the amplifier circuit 912 does not operate. However, the amplifier circuit 912 may operate due to the influence of carriers accumulated in the transistor. In particular, since the saturation voltage is lower than the base-emitter voltage required to turn on the transistor, the NPN transistor 913 is in the off state when the NPN transistor 913 is in the on state. Compared with the situation, malfunction of the PNP transistor 914 is likely to occur.

  On the other hand, in the present embodiment, when the pachinko machine 10 is in a power interruption state, the random delay circuit 602 immediately sends the signal to the amplifier circuit 912 without waiting for the input of the LOW level signal from the D terminal. The LOW level signal is output, and the NPN transistor 913 of the amplifier circuit 912 is turned off based on the input of the LOW level signal. As a result, malfunction of the amplifier circuit 912 is unlikely to occur. Accordingly, supply of operating power to the hard random number clock circuit 900 is suppressed even though the pachinko machine 10 is in the power-off state.

  According to the embodiment described in detail above, the pachinko machine 10 is in the power-on state during the period from the timing when the pachinko machine 10 is in the power-on state until the operating power is supplied to the hard random number clock circuit 900. An irregular delay circuit 602 that varies according to the timing is provided. As a result, the period from when the pachinko machine 10 is turned on until the operation timing of the hard random number clock circuit 900 (output start timing of the hard random number clock signal) varies. Then, it is difficult to grasp the update timing of the jackpot random number counter C1 that is updated based on the input of the hard random number clock signal. Therefore, even if the jackpot random number counter C1 is reset when the pachinko machine 10 is turned on, it is difficult to grasp the update start timing of the jackpot random number counter C1, so “hanging board” or the like is used. It is possible to prevent illegal acts that have occurred.

  Even when the operation timing of the hard random number clock circuit 900 varies, the operation timing of the system clock circuit 312 is constant, and therefore the operation of the hard random number clock circuit 900 is delayed by the irregular delay circuit 602. Even in such a case, the MPU 311 can be operated normally.

  Furthermore, the period of the hard random number clock signal and the period of the system clock signal are set to be different. As a result, even if the period of the system clock signal is grasped, the update timing of the jackpot random number counter C1 to be updated according to the hard random number clock signal is not grasped. Therefore, it is possible to prevent an illegal act of grasping the update timing of the jackpot random number counter C1 from the cycle of the system clock signal and grasping the timing when the jackpot random number counter C1 matches the winning information.

<Sixteenth Embodiment>
In the present embodiment, the configuration related to data erasure is different from that of the fifteenth embodiment, and the object to be irregularly delayed is different from that of the fifteenth embodiment. Therefore, a configuration relating to data erasure in the present embodiment will be described below. In the following description, the description of the same configuration as that of the fifteenth embodiment is basically omitted.

  As shown in FIG. 52, the power and launch control device 243 is provided with a data erase switch 1001 instead of the RAM erase switch 247. The data erasure switch 1001 is a switch that can be operated from the outside of the pachinko machine 10. The data erase switch 1001 is electrically connected to a data erase signal output circuit 1002 provided on the main control board 301.

  The data erasure signal output circuit 1002 is connected to the MPU 311 via the signal line LN5. The data erase signal output circuit 1002 is configured to output a data erase signal to the MPU 311 based on the operation of the data erase switch 1001. When the data erasure signal is input to the MPU 311, the MPU 311 executes processing for initializing RAM data, specifically, processing in steps S 408 and S 409 of the main processing (FIG. 19), and is provided in the ROM 315. It is configured to execute processing for initializing the counter value of the jackpot random number counter C1. As a result, the data initialization process can be performed without the power ON / OFF operation. Therefore, the data initialization process can be easily performed.

  The data erasure signal output circuit 1002 is connected to the power transfer circuit 901 via a signal line LN6 different from the signal line LN5. The data erasure signal output circuit 1002 outputs a HI level signal or a LOW level signal to the power transmission circuit 901 in a situation where the pachinko machine 10 is in the power-on state. The power transmission circuit 901 supplies operating power to the hard random number clock circuit 900 based on the input of the HI level signal from the data erasure signal output circuit 1002.

  More specifically, the power transfer circuit 901 is provided with a reset transistor 1003 on the upstream side with respect to the adjustment resistor 911 and the amplifier circuit 912, as shown in the block circuit diagram of FIG. The reset transistor 1003 is an NPN transistor, the collector is connected to the power supply and launch control board 321 via the power interruption monitoring board 302, and the emitter is connected to the adjustment resistor 911 and the amplifier circuit 912, respectively. The base is connected to the data erasure signal output circuit 1002.

  In the situation where the HI level signal is output from the data erasure signal output circuit 1002, the reset transistor 1003 is in an ON state, and therefore the operating voltage Vcc (specifically, the operating voltage Vcc from the power supply and launch control board 321). (The voltage obtained by subtracting the saturation voltage of the reset transistor 1003) is applied to the irregular delay circuit 602 and the amplifier circuit 912. In this case, on the condition that the HI level signal is output from the irregular delay circuit 602 to the amplifier circuit 912, the operating power is supplied to the hard random number clock circuit 900 via the amplifier circuit 912.

  On the other hand, in the situation where the LOW level signal is output from the data erasure signal output circuit 1002, the reset transistor 1003 is in the OFF state, so the operating voltage Vcc from the power supply and launch control board 321 is an irregular delay. It is not applied to the circuit 602 and the amplifier circuit 912. In this case, as described in the fifteenth embodiment, a LOW level signal is output from the irregular delay circuit 602 to the amplifier circuit 912, and a voltage is applied between the collector and emitter of the PNP transistor 914 in the amplifier circuit 912. Not applied. Therefore, since the amplifier circuit 912 does not operate, no operating power is supplied to the hard random number clock circuit 900.

  Here, the data erasure signal output circuit 1002 is configured to output a LOW level signal over a predetermined specific stop period Ts when the data erasure switch 1001 is operated. The specific stop period Ts is set to be a period longer than one cycle of the pulse signal output from the Schmitt trigger 413.

  The operation of the power transmission circuit 901 based on the operation of the data erasure switch 1001 will be described based on the timing chart of FIG. The timings t59, t60, and t62 indicate the rising timing of the pulse signal from the Schmitt trigger 413. At this timing, the D flip-flop 915 is input to the D terminal at that time. A signal is output from the Q terminal. That is, the cycle T3 of the pulse signal output from the Schmitt trigger 413 is a cycle in which the D flip-flop 915 is synchronized.

  When the data erasure switch 1001 is operated at the timing t58, the signal state from the data erasure signal output circuit 1002 to the power transmission circuit 901 falls from the HI level to the LOW level. Then, no voltage is applied between the collector and emitter of the PNP transistor 914 of the amplifier circuit 912, and a LOW level signal is output from the AND circuit 916. As a result, the supply of operating power to the hard random number clock circuit 900 is stopped.

  Note that a LOW level signal is input to the D terminal of the D flip-flop 915 based on the signal state from the data erasing signal output circuit 1002 becoming the LOW level. On the other hand, since the timing of t58 is not the timing at which the D flip-flop 915 is synchronized, the output state from the Q terminal is maintained at the HI level state.

  Thereafter, at the timing of t59, since the LOW level signal is input to the D terminal, the LOW level signal is output from the Q terminal. Also at the timing of t60, since the LOW level signal is input to the D terminal, the LOW level signal is output from the Q terminal.

  Thereafter, the signal state output from the data erasure signal output circuit 1002 is switched from the LOW level to the HI level at the timing t61 when the specific stop period Ts has elapsed since the operation of the data erasure switch 1001. As a result, a voltage is applied between the collector and emitter of the PNP transistor 914 of the amplifier circuit 912, and an HI level signal is input to the D terminal. On the other hand, since the timing is not the synchronization timing of the D flip-flop 915, the output state from the Q terminal is maintained in the LOW level state.

  Thereafter, at the timing of t62, the D flip-flop 915 synchronizes, so that the HI level signal is output from the Q terminal. As a result, an HI level signal is output from the AND circuit 916. Therefore, the amplifier circuit 912 operates and the supply of operating power to the hard random number clock circuit 900 is resumed. In this case, the operation power supply start timing (timing at t62) is delayed by a delay period DT14 with respect to the timing when the HI level signal is output from the data erase signal output circuit 1002 (timing at t61).

  From the above, when the data erasure switch 1001 is operated, the supply of operating power to the hard random number clock circuit 900 is temporarily stopped. Then, when the period including the specific stop period Ts and the delay period DT14 has elapsed from the operation power supply stop timing, the supply of the operation power is resumed. As described in the eighth embodiment and the like, the delay period DT14 is a period that varies according to the timing at which the pachinko machine 10 enters the power-on state. Therefore, power supply is performed with respect to the operation timing of the data erasure switch 1001. The restart timing varies. Thereby, since it is difficult to grasp the resumption timing of the power supply to the hard random number clock circuit 900, it is possible to suppress an illegal act by the “hanging board” or the like.

  Here, the specific stop period Ts is set longer than the cycle T1 of the pulse signal output from the Schmitt trigger 413. As a result, the D flip-flop 915 is synchronized at least once during the specific stop period Ts, and a LOW level signal is output from the Q terminal. Therefore, the LOW level signal is output from the Q terminal at the elapse timing of the specific stop period Ts. In other words, when the specific stop period Ts has elapsed, the D flip-flop 915 is reliably reset.

  According to this embodiment described in detail above, the data erasure switch 1001, the data erasure signal output circuit 1002 that outputs the HI level signal to the power transmission circuit 901 in a situation where the pachinko machine 10 is in the power-on state, Was established. The data erasure signal output circuit 1002 outputs a data erasure signal to the MPU 311 based on the operation of the data erasure switch 1001, and also outputs a LOW level signal to the power transfer circuit 901 for a specific stop period Ts. It was set as the structure to do. In such a configuration, in a situation where the HI level signal is input from the data erasure signal output circuit 1002, a voltage is applied to the irregular delay circuit 602 and the amplifier circuit 912, while the data erasure signal output circuit 1002 outputs a LOW level. In a situation where a signal is input, a reset transistor 1003 for stopping the application of the operating voltage Vcc to the irregular delay circuit 602 and the amplifier circuit 912 is provided. As a result, the period from the operation timing of the data erasure switch 1001 to the output timing of the hard random number clock signal becomes irregular. Therefore, even when the operation timing of the data erasure switch 1001 is grasped, it is difficult to specify the output timing of the hard random number clock signal. Therefore, in synchronization with the operation of the data erasure switch 1001, it is possible to suppress fraud that specifies the timing at which the value of the jackpot random number counter C1 becomes the winning value.

  In particular, according to such a configuration, the update start timing of the big hit random number counter C1 is irregularly delayed with respect to each of the power-on timing and the operation timing of the data erasure switch 1001. This makes it difficult to grasp the update timing of the jackpot random number counter C1 with respect to the power-on timing and the operation timing of the data erasure switch 1001, respectively. Action can be suppressed.

  The specific stop period Ts is set to be longer than the period (period in which the D flip-flop 915 synchronizes) T3 of the pulse signal output from the Schmitt trigger 413. Thereby, in the situation where the specific stop period Ts has elapsed, the output state from the Q terminal of the D flip-flop 915 is at the LOW level.

  That is, if the specific stop period Ts is shorter than the cycle T3, the D flip-flop 915 may not be synchronized during the specific stop period Ts. In this case, the HI level signal is output from the Q terminal at the elapse timing of the specific stop period Ts. Then, when the HI level signal is output from the data erase signal output circuit 1002, the supply of operating power to the hard random number clock circuit 900 is immediately resumed without delay.

  On the other hand, in this embodiment, since the specific stop period Ts is set longer than the period T3 of the pulse signal output from the D flip-flop 915, the D flip-flop 915 can be surely connected within the specific stop period Ts. Synchronize. As a result, the D flip-flop 915 is reliably reset from when the data erasure switch 1001 is operated until the specific stop period Ts elapses. Therefore, when the HI level signal is output from the data erase signal output circuit 1002, an irregular delay of the delay period DT14 occurs.

<Seventeenth embodiment>
In the fifteenth and sixteenth embodiments, the irregular delay circuit 602 is provided on the path connecting the power interruption monitoring board 302 and the hard random number clock circuit 900, and the irregular delay circuit 602 causes the pachinko machine 10 to be electrically connected. The supply start timing of the power to the hard random number clock circuit 900 with respect to the timing of the on state is changed. On the other hand, in this embodiment, the object of delay is different. The difference will be described below. In addition, about the same structure as the said 15th Embodiment, while attaching | subjecting the same code | symbol, description is abbreviate | omitted.

  As shown in the block diagram of FIG. 55, a clock signal transmission circuit 1101 is provided on a path connecting the hard random number clock circuit 900 and the MPU 311. The clock signal transmission circuit 1101 is electrically connected to the hard random number clock circuit 900 via the two signal lines LN7 and LN8. The hard random number clock circuit 900 outputs a hard random number clock signal via the signal line LN7 and the signal line LN8 in a situation where operating power is supplied.

  The clock signal transmission circuit 1101 will be described with reference to the block circuit diagram of FIG.

  The clock signal transmission circuit 1101 includes an irregular delay circuit 602 and a thyristor 1102. In the thyristor 1102, the anode is connected to the hard random number clock circuit 900 via the signal line LN 7, the cathode is connected to the MPU 311, and the gate is connected to the output side of the irregular delay circuit 602.

  According to such a configuration, when the HI level signal is input to the gate, the hard random number clock signal is output from the cathode of the thyristor 1102 to the MPU 311. On the other hand, when the LOW level signal is input to the gate, the hard random number clock signal is not output to the MPU 311. Thereby, the transmission of the hard random number clock signal to the MPU 311 is controlled in accordance with the signal state input to the gate. The signal input to the gate is supplied from the hard random number clock circuit 900 via the signal line LN8. An irregular delay circuit 602 is provided on the signal line LN8.

  The irregular delay circuit 602 is an integrating circuit, and when the HI level signal is output from the hard random number clock circuit 900, as described in the fifth embodiment, the HI level signal is delayed by a predetermined period and the gate receives the HI level signal. Entered. Since the delay period varies according to the output timing of the HI level signal, the timing at which the thyristor 1102 is turned on varies with respect to the output timing of the hard random number clock signal. As a result, the timing at which the hard random number clock signal is output from the thyristor 1102 varies with respect to the timing at which the hard random number clock circuit 900 outputs the hard random number clock signal.

  When the output state from the hard random number clock circuit 900 falls from the HI level to the LOW level, the state in which the HI level signal is input to the gate due to the discharge effect of the charge accumulated in the capacitor 613 is predetermined. Only maintained for a period. That is, a clock signal having a pulse width different from the pulse width of the hard random number clock signal is input to the gate. Then, a gap occurs between the period in which the HI level signal is input to the gate and the period in which the HI level signal is input to the anode. As a result, a clock signal having a plurality of types of pulse widths and a plurality of types of output intervals is output from the thyristor 1102 to the MPU 311. In this case, since the jackpot random number counter C1 is updated based on the input of the clock signal, the update interval of the jackpot random number counter C1 varies. Therefore, it is more difficult to specify the timing when the value of the jackpot random number counter C1 becomes the winning value. In this case, the capacitance of the capacitor 613 and the resistance value of the resistor 614 may be set so that the clock signal input to the gate and the hard random number clock signal are not synchronized.

  According to the embodiment described in detail above, the clock signal transmission circuit 1101 for transmitting the hard random number clock signal is provided on the path connecting the hard random number clock circuit 900 and the MPU 311. Based on the input of the hard random number clock signal from the hard random number clock circuit 900, the clock signal transmission circuit 1101 outputs a clock signal corresponding to the hard random number clock signal to the MPU 311 and also the hard random number clock signal. A period from the input timing of the clock signal to the output timing of the corresponding clock signal is varied according to the input timing. Accordingly, the period from the output timing of the hard random number clock signal to the input timing at which the clock signal corresponding to the hard random number clock signal is input to the MPU 311 is irregular. Therefore, fraudulent acts caused by “hanging board” or the like can be suppressed. That is, in the fifteenth embodiment, the object to be irregularly delayed is the “period from when the pachinko machine 10 is turned on until the operating power is supplied to the hard random number clock circuit 900”. On the other hand, in the present embodiment, the object to be irregularly delayed is that the clock signal corresponding to the hard random number clock signal is output from the MPU 311 after the hard random number clock circuit 900 outputs the hard random number clock signal. The period until input is made.

<Other embodiments>
In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, each of the following configurations may be applied alone to the configuration of the above embodiment, or may be applied to the configuration of the above embodiment in a predetermined combination. Moreover, you may apply the following each structure to embodiment which is not illustrated as an application object of the structure.

  (1) In the first to fourth embodiments, the winning value of the jackpot random number counter C1 is a predetermined fixed value, and it is determined whether or not the value of the jackpot random number counter C1 matches the winning value. However, the present invention is not limited to this. For example, a predetermined range is set as a winning range out of the possible ranges of the jackpot random number counter C1, and the value of the jackpot random number counter C1 is determined as the winning range. It is good also as a structure which determines whether it is in the range. Even in this case, the present invention can be applied.

  This configuration will be described with reference to the flowchart in FIG. FIG. 57 is a flowchart showing a jackpot determination process for determining whether or not the acquired value of the jackpot random number counter C1 corresponds to the winning value. In this modification, the numerical value range that the big hit random number counter C1 can take is set to “0 to 65535”. More specifically, the counter circuit 317 includes two 8-bit shift registers, and each shift register is updated based on the input of a hard random number clock signal. When a game ball enters the operation port 84, the MPU 311 acquires information of each shift register, generates the value of the big hit random number counter C1 from the acquired information, and stores it in the reserved ball storage area. To do.

  In this case, if the configuration is such that the jackpot random number counter C1 is generated by arbitrarily combining the bits of each shift register, the value of the jackpot random number counter C1 is difficult to identify from the information of each shift register, and therefore, from the viewpoint of preventing fraud Is excellent from.

  First, in step S1101, a process for setting the winning value PV is executed. Specifically, the ROM 315 is provided with a storage area in which a success / failure table in which a gaming state and a winning value PV are set in a one-to-one correspondence is stored. The winning value PV corresponding to the gaming state is set. For example, the winning value PV is set to “1310” in the probability variation state, and the winning value PV is set to “655” in the normal state.

  Thereafter, in step S1102, in the current jackpot determination process, the winning value PV is added to the value of the jackpot random number counter C1 that is the target of the jackpot determination to set a new jackpot random number counter C1.

  In a succeeding step S1103, a determination process is executed as to whether or not the value of the new jackpot random number counter C1 updated in the step S1102 exceeds “65535”. In the determination process, if it is determined that the value of the jackpot random number counter C1 does not exceed “65535”, it means that the current game result is out. In this case, in step S1104, the outlier information is stored in the outlier information storage area provided in the RAM 316. On the other hand, if it is determined that the value of the jackpot random number counter C1 exceeds “65535”, it means that the current game result is a jackpot winning. In this case, the jackpot winning information is stored in the jackpot winning information storage area provided in the RAM 316 in step S1105.

  Here, if the winning value PV is set to “655”, if the value of the jackpot random number counter C1 is any value in the numerical value range of “64881 to 65535”, the jackpot winning is set. In this case, since the numerical value range that the jackpot random number counter C1 can take is “0 to 65535”, the winning probability is about 1/100.

  In addition, if the winning value PV is set to “1310”, if the value of the jackpot random number counter C1 is any value in the numerical range of “64226 to 65535”, the jackpot winning is set. In this case, the winning probability is 1/50.

  From the above, the value of the jackpot random number counter C1 to be the jackpot winning is within a predetermined numerical range, and the winning probability is set to the predetermined probability by changing the winning value PV added to the jackpot random number counter C1. can do.

  Even in such a configuration, by changing the output interval of the hard random number clock signal, every time the big hit random number counter C1 makes one round, the value of the big hit random number counter C1 is the period until the big hit random number counter C1 makes one round. Since the winning period and winning probability fluctuate, the jackpot is intentionally generated by illegally outputting a signal in accordance with the period when the value of the jackpot random number counter C1 is the winning value. Fraudulent behavior can be suppressed.

  (2) In the first to third embodiments, the frequency conversion circuit 401 is composed of the local oscillation circuit 401a and the mixer circuit 401b. However, the present invention is not limited to this, and an AC voltage input at an arbitrary frequency is used. What is necessary is just to convert into the alternating voltage of a fixed frequency, for example, what combined the AC / DC converter and the DC / AC inverter may be used. In this case, an AC voltage having a constant frequency can be obtained regardless of the frequency of the AC voltage input from the commercial power supply. However, from the viewpoint of simplification of the configuration and the amount of heat generation, the combination of the local oscillation circuit 401a and the mixer circuit 401b is superior.

  For example, as the frequency conversion circuit 401, a 6 multiplication circuit and a 5 multiplication circuit may be provided. In this case, when an AC voltage of 50 Hz is input, the frequency is converted using a 6-fold circuit, whereas when an AC voltage of 60 Hz is input, the frequency is converted using a 5-times circuit. To. Thereby, even if it is a case where the alternating voltage of which frequency is input, the alternating voltage of 300 Hz can be obtained.

  (3) In the first to third embodiments, the CR oscillation circuit is used as the local oscillation circuit 401a. However, the present invention is not limited to this, and for example, a clap oscillation circuit may be used. However, when the oscillation frequency is a low frequency, the shape of the coil used in the clap oscillation circuit becomes large. Therefore, the CR oscillation circuit is superior from the viewpoint of space saving.

  Further, a voltage controlled oscillation circuit (VCO) may be used as the local oscillation circuit 401a. In short, any oscillation circuit capable of changing the output frequency is optional.

  (4) In the first embodiment, the numerical range of the jackpot random number counter C1 is set so that the number of counter terms of the jackpot random number counter C1 is not a multiple of the number of pulse signals included in the pulse signal group. However, the present invention is not limited to this. For example, the numerical range of the big hit random number counter C1 may be set so that the number of counter terms is a prime number larger than the number of signals. Thereby, since the degree of freedom of the number of signals can be increased, even if the number of signals is changed, it is possible to easily cope with the change.

  (5) In the second embodiment, the random number initial value counter CINI is provided as the initial value of the jackpot random number counter C1, and the random number initial value counter CINI is updated in the timer interrupt process. However, the present invention is not limited to this. For example, instead of the random number initial value counter CINI, a count-up counter that is incremented by one every time the jackpot random number counter C1 makes one round may be provided. Even in this case, every time the jackpot random number counter C1 makes one turn, the period from when the value of the jackpot random number counter C1 becomes the initial value to the winning value, and the value of the jackpot random number counter C1 become the winning value. Since the period of time changes, it is difficult to grasp the timing at which the value of the jackpot random number counter C1 becomes the winning value.

  Details of this modification will be described with reference to the flowchart of FIG. 58 is the same as the process of step S601, the processes of step S1202 to step S1204 are the same as those of step S603 to step S605, and the processes of step S1206 to step S1209 are the same as those of step S606. Since it is the same process as the process of step S609, description is abbreviate | omitted.

  In this modification, instead of the process of updating the random number initial value counter CINI (the process of step S602 in FIG. 24), the process of updating the pulse shift counter SC in step S1205 is executed. Is different. The pulse shift counter SC has a numerical value range corresponding to the number of signals, and is incremented by 1 within the numerical value range every time the update timing is reached, and returns to “0” after reaching the maximum value. Yes. The numerical range will be specifically described. When the number of pulse signals included in the pulse signal group is “m”, the numerical range of the pulse shift counter SC is set to “0 to m−1”. The pulse shift counter SC is updated when it is determined that the big hit random number counter C1 has made one round.

  According to such a configuration, even if the numerical range of the jackpot random number counter C1 is “0 to N” and N + 1 = K × m (K: natural number), every time the jackpot random number counter C1 makes one round. In addition, the initial value varies and the value of the jackpot random number counter C1 corresponding to the pulse signals included in the pulse signal group varies. Thereby, every time the jackpot random number counter C1 makes one turn, a period from when the value of the jackpot random number counter C1 becomes an initial value until it becomes a winning value, and a period during which the value of the jackpot random number counter C1 is a winning value Fluctuates.

  Further, when the numerical range of the number of signals is smaller than the numerical range of the jackpot random number counter C1 (N> m), the capacity required for the pulse shift counter SC can be reduced as compared with the random number initial value counter CINI. Further, the pulse shift counter SC is updated only when the jackpot random number counter C1 makes one round, while the random number initial value counter CINI is updated every time the timer interrupt process is executed. Thereby, the update frequency of the pulse shift counter SC is smaller than the update frequency of the random number initial value counter CINI. Therefore, the processing load is reduced.

  However, since the random number initial value counter CINI is superior to the pulse shift counter SC in terms of irregularity, the second embodiment is superior from the viewpoint of fraud suppression.

  (6) In the first to fourth embodiments, the counter circuit 317 is configured to update the jackpot random number counter C1 in synchronization with the rising edge of the pulse signal. However, the present invention is not limited to this. The big hit random number counter C1 may be updated in synchronization with the fall. The counter circuit 317 may be configured to update the jackpot random number counter C1 in synchronization with both rising and falling edges of the pulse signal. In this case, since the update frequency of the jackpot random number counter C1 is increased and the number of types of update intervals is increased as compared with the configuration in which the update is performed in synchronization with only one of the rising edge or the falling edge of the pulse signal, the number of types of update intervals increases. Identification can be made more difficult.

  (7) In the second embodiment, the random number initial value counter CINI is updated in the timer interrupt process. However, the present invention is not limited to this. For example, the random number initial value counter CINI is updated in the fluctuation counter update process in step S508 in the normal process. It is good also as a structure. Thereby, the randomness of the random number initial value counter CINI can be improved.

  In addition, the random number initial value counter CINI is not limited to the configuration updated by software processing relating to the progress of the game. For example, a dedicated counter circuit is provided and a hard random number clock signal or a system clock signal is input. Thus, the random number initial value counter CINI may be updated.

  Further, in this case, a determination circuit for determining whether or not the big hit random number counter C1 has made one round, and when it is determined that the big hit random number counter C1 has made one round, the random number initial value counter CINI at that time is used as the big hit random number counter C1. A circuit for writing as an initial value may be separately provided. As a result, the jackpot random number counter C1 operates independently without depending on the MPU 311 including the setting of the initial value. Therefore, it is illegal to specify the value of the jackpot random number counter C1 through software processing. Action can be suppressed. However, the second embodiment is superior from the viewpoint of simplification of the configuration.

  (8) In the first to third embodiments, the specific frequency of the AC voltage output from the frequency conversion circuit 401 is set so that the trigger interval is longer than the cycle of the timer interrupt process. For example, the specific frequency may be set so that the trigger interval is shorter than the timer interrupt processing cycle. In this case, since the update interval of the jackpot random number counter C1 is shortened, the period during which the value of the jackpot random number counter C1 is the winning value is shortened, and it is difficult to output an illegal signal during the period.

  However, in the second embodiment, when the specific frequency is set so that the trigger interval is shorter than the timer interrupt processing cycle, it may not be possible to determine that the big hit random number counter C1 has made one round. In this case, when the big hit random number counter C1 makes one round, a stop circuit for temporarily stopping the update of the big hit random number counter C1 is provided. In the timer interrupt process, the update of the big hit random number counter C1 is stopped by the stop circuit. It is good to determine whether or not. However, since the period when the value of the jackpot random number counter C1 in the stopped state can be longer than the period when it is other values, pay attention to the viewpoint of suppressing fraud and the viewpoint of stabilizing the jackpot winning probability. For example, the specific frequency may be set so that the trigger interval is longer than the timer interrupt processing cycle.

  Note that, as shown in (7), when the jackpot random number counter C1 makes one round, and when it is judged by the judgment circuit that the circuit has made one round, the initial random number at that time When a circuit for writing the counter CINI as the initial value of the jackpot random number counter C1 is separately provided, the specific frequency is set so that the trigger interval is shorter than the timer interrupt processing cycle while avoiding the above-described inconvenience. be able to.

  In the fourth embodiment, the frequency dividing ratio of the frequency dividing circuit 502 may be determined so that the trigger interval is shorter than the timer interrupt processing cycle.

  (9) In each of the first to third embodiments, the hard random number clock circuit 313 converts the AC voltage of the commercial power source supplied from the power source and the launch control board 321 to generate the hard random number clock signal. However, the present invention is not limited to this. For example, a clock circuit that has a dedicated crystal resonator and independently outputs a clock signal having a predetermined frequency may be used. In this case, the frequency conversion circuit 401 and the signal conversion circuit 402 are not necessary. However, in terms of the simplification of the configuration and the manufacturing cost, the configuration that converts the AC voltage from the commercial power supply is superior.

  (10) In the first to fourth embodiments, the update interval of the jackpot random number counter C1 is changed by changing the rising interval of the input pulse signal. However, the present invention is not limited to this. A programmable counter that counts the number of signal inputs may be separately provided so that the jackpot random number counter C1 is updated when the pulse signal is input a predetermined number of times, and the predetermined number of times may vary. Thereby, even if the rising interval of the pulse signal that triggers the update of the big hit random number counter C1 does not change, the update interval of the big hit random number counter C1 can be changed. Therefore, it is difficult to specify the update timing of the big hit random number counter C1. However, if attention is paid to the simplification of the configuration of the counter circuit 317, the first embodiment is superior.

  (11) In the first to fourth embodiments, the modulation is performed so that the output interval of the pulse signal becomes two types. However, the modulation is not limited to this, and for example, there may be three types or four types. As the number of types of output intervals of the pulse signal increases, the number of types of the period in which the jackpot random number counter C1 is a winning value and the period required for the jackpot random number counter C1 to make one round increase. In this case, each time the jackpot random number counter C1 makes one round, these periods may be changed sequentially. This makes it more difficult to specify the update timing of the jackpot random number counter C1. However, from the viewpoint of simplification of the configuration of the modulation circuit 314, it is preferable that the number of types of output intervals of the pulse signal is small.

  In addition, as a specific configuration in which the output interval of the pulse signal is three types and four types, a D flip-flop having a preset input terminal (PR input terminal) is used in addition to a configuration in which a D flip-flop and an XOR circuit are further provided. Thus, a configuration in which a signal is input to the PR input terminal at a predetermined timing can be considered.

  Further, although the D flip-flop is used for the modulation circuit 314 that varies the output interval of the pulse signal, the invention is not limited to this, and any of various flip-flops such as a JK flip-flop may be used. Furthermore, the invention is not limited to the XOR circuit, and any of various logic circuits such as an AND circuit may be used.

  (12) In the first to fourth embodiments, the jackpot random number counter C1 is updated based on the input of the hard random number clock signal. However, the present invention is not limited to this, and the hard random number clock signal is input. Based on the above, it is possible to update the counters other than the jackpot random number counter C1.

  (13) In the first to fourth embodiments, the game progress control is performed based on the input of the system clock signal, and the jackpot is based on the input of the hard random number clock signal. The random number counter C1 is updated. However, the present invention is not limited to this. For example, the big hit random number counter C1 is updated based on the input of the system clock signal and the hard random number clock signal. It is good also as a structure which switches alternately with the 2nd aspect performed based on an input. This makes it more difficult to specify the update timing of the jackpot random number counter C1.

  In addition, as these specific structures, the structure which provides the switching element which switches the input of the clock signal for hard random numbers, and the input of the clock signal for systems, for example can be considered.

  (14) Although the modulation circuit 314 is provided in the first to fourth embodiments, the modulation circuit 314 may not be provided. Thereby, simplification of a structure and speeding-up of a process can be achieved.

  Even in this case, the hard random number clock signal and the system clock signal are set to have different periods, so the hard random number clock signal period must be identified from the system clock signal period. Has become difficult. Thereby, since it is difficult to specify the update timing of the jackpot random number counter C1, it is difficult to specify the timing at which the value of the jackpot random number counter C1 becomes the winning value.

  However, since it is more difficult to specify the update timing of the jackpot random number counter C1 in the configuration in which the modulation circuit 314 is provided, the configuration in which the modulation circuit 314 is provided is preferable from the viewpoint of preventing fraud.

  (15) In the first to fourth embodiments, the counter circuit 317 that updates the jackpot random number counter C1 is provided based on the input of the hard random number clock signal. However, the present invention is not limited to this. A program for updating the jackpot random number counter C1 based on the input of the clock signal may be provided. In this case, the frequency of the hard random number clock signal may be set so that the program operates normally and smooth processing is performed with other processing. Accordingly, the update process is performed at a predetermined frequency, and the start timing of the acquisition process is excessively delayed in order to synchronize the acquisition process of the big hit random number counter C1 and the update process of the big hit random number counter C1. Can be avoided.

  In this case, the hard random number clock signal may be a signal output from the modulation circuit 314. As a result, the processing period of the program changes, and as a result, the update interval of the jackpot random number counter C1 changes.

  (16) In the first to fourth embodiments, the counter circuit 317 for updating the jackpot random number counter C1 is provided. However, the present invention is not limited to this. For example, the jackpot random number counter C1 is used in timer interrupt processing or normal processing. It is good also as a structure which updates. In this case, the update interval of the big hit random number counter C1 may be changed in software processing. This makes it difficult to specify the update timing of the jackpot random number counter C1.

  As a specific configuration, a loop counter that is updated every time the timer interrupt process is executed is separately provided, and when the value of the loop counter is a predetermined value, the jackpot random number counter C1 is updated, A configuration in which the predetermined value is varied is conceivable.

  (17) In the first to third embodiments, the frequency conversion circuit 401 and the modulation circuit 314 are mounted on the main control board 301. However, the present invention is not limited to this. For example, the power interruption monitoring board 302 or the power supply And it is good also as a structure mounted in the launch control board | substrate 321. FIG. However, mounting on the main control board 301 is superior in preventing physical fraud against these.

  (18) In the first to third embodiments, the AC power supply unit 321d, the frequency conversion circuit 401, and the signal conversion circuit 402 are attached to the pachinko machine 10. However, the present invention is not limited to this, and the pachinko machine It is good also as a structure attached to the exterior of 10.

  (19) In the first to third embodiments, the AC power supply unit 321d is provided on the power supply and launch control board 321. However, the present invention is not limited to this, and the power supply monitoring board 302 may be provided on the power interruption monitoring board 302. It may be provided independently. However, the configuration in which the AC power supply unit 321d is integrated into the power supply and launch control board 321 is superior from the viewpoint of simplification of the configuration in the power supply system.

  (20) In the first to third embodiments, the Schmitt trigger 413 is used as the signal conversion circuit 402. However, the invention is not limited to this, and a comparator having the same upper threshold voltage and lower threshold voltage may be used. In short, any comparator circuit that performs comparison with the input voltage based on at least one reference voltage and outputs a signal based on the comparison result may be used. However, the configuration having both the upper threshold voltage and the lower threshold voltage such as the Schmitt trigger 413 is superior from the viewpoint of the stability of the output waveform. In addition, although it was set as the structure which compares a reference voltage and an input voltage, it is good also as a structure which performs signal control based on the comparison with a reference current and the electric current which has actually flowed.

  (21) In the first to third embodiments, the system clock circuit 312, the hard random number clock circuit 313, and the modulation circuit 314 are provided on the main control board 301. However, the present invention is not limited to this. It may be incorporated in. In this case, these circuits are connected to the ROM 315 and the like via wiring in the MPU 311.

  Similarly, in the fourth embodiment, the system clock circuit 312, the clock conversion circuit 501, and the modulation circuit 314 may be incorporated in the MPU 311.

  (22) In the first to fourth embodiments, the period in which the jackpot random number counter C1 is the winning value is repeated with “Ta, Tb” as the unit period. However, the present invention is not limited to this. “Ta, Tb, Tb, Ta” may be repeated as a unit period. Even in this case. The overall winning probability as a whole remains unchanged. However, in this case, every time the jackpot random number counter C1 rotates twice, the period during which the jackpot random number counter C1 is the winning value varies. For this reason, the first to fourth embodiments in which the period of the winning value is changed every time the jackpot random number counter C1 makes one turn are superior from the viewpoint of fraud suppression.

  The same applies to the period required for the jackpot random number counter C1 to make one round.

  (23) In the fourth embodiment, the frequency divider 502 is used as the frequency conversion means. However, the frequency converter is not limited to this, and for example, a multiplier may be used. Even in this case, since the system clock signal and the hard random number clock signal have different periods, the effect of the fourth embodiment can be obtained.

  (24) In the first to fourth embodiments described above, the jackpot random number counter C1 is not updated in a situation where the pachinko machine 10 is not powered on (power interruption state). The big hit random number counter C <b> 1 may be updated in a situation where it is not input. Thereby, since the value of the jackpot random number counter C1 varies according to the timing when the power is turned on, it is difficult to specify the value of the jackpot random number counter C1.

  As a specific configuration, operating power may be supplied to the hard random number clock circuit 313, the modulation circuit 314, and the counter circuit 317 from the power-off power supply unit 321 c in the power-off state.

  (25) In the first to fourth embodiments described above, every time the big hit random number counter C1 makes one round, the period required for the big hit random number counter C1 to make one round is changed. However, for example, every time the big hit random number counter C1 makes two rounds, the period required for the big hit random number counter C1 to make one round may be changed. The point is that the period required for the jackpot random number counter C1 to make one round may be changed by using the jackpot random number counter C1 to make one round as a trigger.

  (26) In the fifth to twelfth embodiments, the reset signal is delayed by the irregular delay circuit 602. However, the present invention is not limited to this, and the start timing of power supply to the MPU 311 may be delayed. Good.

  (27) In the fifth to twelfth embodiments, the MPU 311 is configured to operate with the LOW level signal, but is not limited thereto, and may be configured to operate with the HI level signal. In such a case, it is necessary to use an AND circuit instead of the NAND circuit 612. However, the configuration that operates with the LOW level signal is superior from the viewpoint of noise countermeasures.

  (28) In any of the seventh to eleventh embodiments, each D flip-flop is configured to be synchronized with the rising edge of the pulse signal, but is not limited thereto, and may be configured to be synchronized with the falling edge. In such a case, it is necessary to change the input / output of the reset circuit 601 or the like correspondingly. Further, a flip-flop synchronized with the rising edge and a flip-flop synchronized with the falling edge may be combined. This makes it possible to generate pulse signals with different output intervals, particularly as in the eleventh embodiment. Moreover, it is good also as a structure which synchronizes with both rising and falling. However, it is preferable to use a configuration that synchronizes only with rising or falling because the range of the delay period is widened, from the viewpoint of the variability of the delay period.

  (29) In any of the seventh to eleventh embodiments, in order to obtain a desired pulse signal, an AC power supply unit 631 that outputs an AC voltage from a commercial power supply, and a signal that converts the AC voltage into a pulse signal However, the present invention is not limited to this, and a pulse generation circuit that generates a pulse signal such as an oscillation circuit using a crystal resonator may be provided. However, the configuration in which the AC power supply unit 631 and the signal conversion circuit 402 are provided is superior in terms of simplification of the configuration because the commercial power source is used as it is.

  Moreover, although the AC power supply unit 631 and the signal conversion circuit 402 are attached to the pachinko machine 10, the present invention is not limited to this, and the pachinko machine 10 may be attached to the outside of the pachinko machine 10.

  Moreover, although the Schmitt trigger 413 used the inverter type thing, it is not restricted to this, You may use a buffer type thing.

  (30) In any of the seventh to eleventh embodiments, the AC power supply unit 631 is configured to have a full-wave shaping circuit. However, the configuration is not limited to this. For example, from an AC power supply unit 321d, The voltage may be output as it is.

  (31) In any of the seventh to eleventh embodiments, the pulse signal is a short wave having a predetermined pulse width, but may be a sawtooth wave, a triangular wave, or the like. The shape of the waveform is arbitrary. Further, the pulse signal may be inverted. In such a case, it is necessary to set each D flip-flop and logic circuit correspondingly.

  (32) In any one of the seventh to eleventh embodiments, the pulse signal output from the Schmitt trigger 413 of the signal conversion circuit 402 is output regardless of the power-on state and power-off state of the pachinko machine 10. However, it is not limited to this. For example, at least one operation of the AC power supply unit 631 or the signal conversion circuit 402 may not be performed. Specifically, a configuration in which power is not supplied to the Schmitt trigger 413 of the signal conversion circuit 402 under a power interruption state may be employed, or a configuration in which power is not supplied to the AC power supply unit 631 may be employed. Moreover, it is good also as a structure which does not supply electric power to both the Schmitt trigger 413 and the alternating current power supply part 631. In such a case, the power consumption of the pachinko machine 10 in the power-off state can be reduced, so that it is possible to reduce the charge capacity of the power-supply unit 321c for power interruption or to maintain the standby state for a long time. However, if the pachinko machine 10 enters the power-on state when the AC voltage is equal to or higher than the upper limit threshold voltage of the Schmitt trigger 413, the pulse signal output may rise from the LOW level to the HI level at the same time as the power-on state. Then, since the D flip-flops are synchronized at the same time as the power-on state is established, there is a possibility that no delay occurs. Therefore, in such a case, each D flip-flop may be configured to be synchronized with the switching from the HI level signal to the LOW level signal. Thereby, the said inconvenience can be avoided.

  Note that, when power is not supplied to the AC power supply unit 631 and the Schmitt trigger 413 in the power-off state, no pulse signal is output in the tenth embodiment and the eleventh embodiment. Therefore, the flip-flops 663, 664, 672 are not output. , 673 and 674 are not updated, but the output state in the power interruption state is maintained, so that the effects described in the tenth embodiment and the eleventh embodiment can be obtained.

  In the tenth embodiment and the eleventh embodiment, the AC power supply unit 631 is configured such that power is always supplied from a commercial power source regardless of the power-on state and power-off state of the pachinko machine 10. However, the present invention is not limited to this, and in a power interruption state, power may be supplied from the power supply unit 321c for power interruption. Even in this case, the effects of the present invention can be achieved.

  (33) In the eighth embodiment, the D flip-flop 651 is configured to output from the Q1 terminal a signal corresponding to the input state of the signal input to the D1 terminal in synchronization with the rising edge of the pulse signal. Further, it may be configured to further include pulse signal delay means for outputting the pulse signal delayed by a predetermined period after the pulse signal is input. Specifically, a pulse signal delay unit is provided on a path connecting the Schmitt trigger 413 and the D flip-flop 651, and the pulse signal output from the Schmitt trigger 413 is transmitted to the D flip-flop 651 via the pulse signal delay unit. It may be configured to be input to the CLK terminal.

  As the pulse signal delay means, for example, the integration circuit described in the fifth embodiment can be considered. Further, a monostable multivibrator may be provided instead of the integration circuit. In such a case, it is necessary to provide an electrical path for electrically connecting the monostable multivibrator and the power interruption monitoring board 302 and to separately provide an integration circuit on the electrical path. The monostable multivibrator has an A terminal as an input terminal and a positive logic output terminal (Q terminal) and a negative logic output terminal (Q bar terminal) as output terminals. The output terminal of the Schmitt trigger 413 may be connected to the A terminal, and the CLK terminal of the D flip-flop 651 may be connected to the Q bar terminal. According to such a configuration, when the pulse signal is input to the monostable multivibrator, that is, when the signal input to the A terminal rises from the LOW level to the HI level, the pulse signal is output from the Q bar terminal with a delay of a predetermined period. Signal rises from LOW level to HI level. As a result, the timing at which the D flip-flop 651 synchronizes with the rising edge of the pulse signal is delayed. Therefore, it is difficult to grasp the output timing of the LOW level signal from the NAND circuit 612.

  Here, since the D flip-flop 651 is configured to synchronize with the rising edge of the signal input to the CLK terminal, that is, with a sudden change in the input voltage, there is a possibility that the D flip-flop 651 does not synchronize with a gradual change in the input voltage. Then, there is a possibility that the D flip-flop 651 does not synchronize due to a delay due to a gradual voltage change of the integration circuit. On the other hand, in the case of a monostable multivibrator, the D flip-flop 651 is easy to synchronize because the output signal is immediately switched from the LOW level to the HI level after a predetermined period from the input of the pulse signal. Therefore, it is possible to suitably synchronize the D flip-flop 651 while delaying the pulse signal. That is, the monostable multivibrator has a function of delaying and outputting a pulse signal having an edge that can be synchronized with the D flip-flop 651 to the D flip-flop 651 that is a transition unit based on the input of the pulse signal. In addition, since the monostable multivibrator uses an integration circuit, the delay period of the monostable multivibrator varies depending on the residual charge amount. It is possible to prevent fraud using the “hanging board” more preferably.

  Note that this configuration may be applied to the ninth to eleventh embodiments. In such a case, a monostable multivibrator as a pulse signal delay unit is provided on a path connecting the modulation circuit 662 and the first D flip-flop 661 or on a path connecting the modulation circuit 671 and the first D flip-flop 661. Good.

  (34) In the eighth embodiment, the Schmitt trigger 413 is configured to operate even when the pachinko machine 10 is in the power-off state, but is not limited thereto. For example, when the pachinko machine 10 is in a power interruption state, the operation power is not supplied to the Schmitt trigger 413, and the operation start timing of the Schmitt trigger 413 and the output start timing of the reset signal from the reset circuit 601 are shifted. With this configuration, the same operational effects as those of the eighth embodiment can be obtained.

  (35) In the fifth to twelfth embodiments, the reset circuit 601 and the irregular delay circuit 602 are supplied with operating power from the power source and the launch control board 321 via the power interruption monitoring board 302. However, the present invention is not limited to this, and the reset circuit 601 and the irregular delay circuit 602 may be directly connected to the power source and the launch control board 321 to receive power.

  In addition, the power failure monitoring board 302 and the main control board 301 are separately provided. However, the present invention is not limited to this. For example, the power failure monitoring circuit 632 mounted on the power interruption monitoring board 302 is used as the main control board. It is good also as a structure mounted in 301. FIG.

  (36) In the fifth to seventeenth embodiments, the irregular delay circuit 602 is mounted on the main control board 301. However, the present invention is not limited to this. For example, the irregular delay circuit 602 may be provided on the power interruption monitoring substrate 302. Moreover, it is good also as a structure provided in a power supply and the discharge control board | substrate 321 grade | etc.,. However, the configuration mounted on the main control board 301 is superior from the viewpoint of simplifying the configuration because it is not necessary to separately provide wiring and the like. The main control board 301 is housed in a board box 163, and the board box 163 is fixed by a sealing portion 164 in an unopenable or difficult state. Therefore, by mounting the irregular delay circuit 602 on the main control board 301, illegal acts on the irregular delay circuit 602 can be prevented.

  (37) In the fifth embodiment or the sixth embodiment, one capacitor 613 is connected in parallel to the resistor 614. However, the present invention is not limited to this, and a plurality of capacitors having different capacitances are used. It is good also as a structure connected in parallel. In this case, a switch may be provided on a path connecting each capacitor 613 and resistor 614. Thereby, since an electrostatic capacitance changes by on / off control of a switch, a charge period and a discharge period change. Then, since the delay period varies, the delay period can be more preferably irregular. Therefore, it is difficult to grasp the timing of winning the jackpot. A plurality of capacitors having the same electrostatic capacitance may be connected in parallel. In such a case, the on / off control of the switch may be executed so as to change the combined capacitance.

  (38) In any of the fifth to ninth embodiments, the power supply and launch control board 321 is provided with the power supply unit 321c for power interruption, and the power supply unit 321c for power interruption is provided in the power interruption state of the pachinko machine 10. However, the present invention is not limited to this, and the power interruption unit 321c may be omitted. In this case, the RAM data is erased each time the pachinko machine 10 is turned off, and the RAM data is initialized every time the pachinko machine 10 is turned on. Even in this case, the effects of the present invention can be achieved.

  (39) In the fifth to eleventh embodiments, the signal line LN3 and the signal line LN4 that connect the reset circuit 601 and the NAND circuit 612 are provided. However, the present invention is not limited to this, and the signal line LN3 is not provided. Also good. However, in this case, since the output timing of the HI level signal from the NAND circuit 612 is delayed with respect to the timing when the power is cut off, the fifth to eleventh above-mentioned points are taken from the viewpoint of the rapid fall processing of the MPU 311. The embodiment is superior.

  (40) In the twelfth embodiment, the value of the initial value random number counter CF is constantly updated regardless of the power-on state and power-off state of the pachinko machine 10, but the present invention is not limited to this. It is good also as a structure updated only to an on state. In such a case, a storage means for storing the value of the initial value random number counter CF in the case of a power interruption state may be separately provided, and the value stored in the storage means may be read in the initial value setting process. Even in this configuration, since the value of the initial value random number counter CF varies according to the timing when the power interruption occurs, the initial value of the jackpot random number counter C1 set in the initial value setting process varies. Will be. Thereby, the same effect as that of the twelfth embodiment can be obtained. However, since the value of the initial value random number counter CF is constantly updated, the counter value is more difficult to grasp as compared with the configuration in which the value of the initial value random number counter CF is stored. This is superior from the viewpoint of preventing fraud using "hanging substrates".

  (41) In the twelfth embodiment, the values of the initial value random number counter CF and the jackpot random number counter C1 are updated differently. However, the present invention is not limited to this. For example, the value of the initial value random number counter CF is updated. The interval may be different from the update interval of the value of the big hit random number counter C1. Specifically, the counter update circuit 701 is provided with two circuits that output pulse signals at different periods, and the value of the jackpot random number counter C1 is the pulse signal output from one of the two circuits. Synchronously, 1 is added in order within the range of 0 to 676, and after reaching the maximum value (ie, 676), the value returns to 0. On the other hand, the value of the initial value random number counter CF is output from another circuit. In the same manner as the jackpot random number counter C1, it is preferable to add one by one in the range of 0 to 676, reach the maximum value (that is, 676), and then return to 0. As a result, the period of the pulse signal synchronized with the big hit random number counter C1 and the period of the pulse signal synchronized with the initial value random number counter CF are different, so the value update interval of the big hit random number counter C1 and the initial value random number The update interval of the value of the counter CF is different. Even in this case, the initial value random number counter CF and the jackpot random number counter C1 can be prevented from being completely synchronized.

  (42) In the twelfth embodiment, the irregular delay circuit 602 is provided on the path connecting the reset circuit 601 and the MPU 311. However, the present invention is not limited to this. For example, the irregular delay circuit 602 is not provided. Also good. Even in such a configuration, since the value of the initial value random number counter CF is constantly updated, the initial value of the jackpot random number counter C1 acquired in the initial value setting process varies according to the acquisition timing. Thereby, since it is difficult to grasp the initial value of the jackpot random number counter C1, it is possible to suppress an illegal act using a “hanging board” or the like.

  In this case, a storage area for storing a different fixed value (for example, a serial number) for each pachinko machine 10 is further provided. In the initial value setting process, the initial value is set based on the value of the initial value random number counter CF and the fixed value. It is good also as a structure which sets. This makes it difficult to specify the initial value, and the initial value set for each pachinko machine 10 is different. Therefore, it is possible to more appropriately suppress fraud using the “hanging board” or the like.

  (43) In the twelfth embodiment, the initial value random number counter CF is also used as the random number initial value counter CINI. However, the present invention is not limited to this. However, the twelfth embodiment is preferable from the viewpoint of processing load, manufacturing cost, and space saving.

  (44) In the twelfth embodiment, the initial value random number counter CF for determining the initial value of the jackpot random number counter C1 at the time of power-on is provided. However, the present invention is not limited to this. For example, instead of the initial value random number counter CF, a separate timer counter circuit may be provided. The timer counter starts to operate (update) based on the output of the reset signal from the reset circuit 601, and the initial value of the jackpot random number counter C1 is set based on the value of the timer counter at the timing when the reset signal is input to the MPU 311. It is good also as a structure to determine. In this case, since the period from the reset signal output timing from the reset circuit 601 to the input timing to the MPU 311 fluctuates due to the irregular delay circuit 602, the timing at which the reset signal is output by the “hanging board” or the like is grasped. Even in such a case, it is difficult to grasp the value of the timer counter. Therefore, since it becomes difficult to grasp the initial value of the jackpot random number counter C1 determined based on the value of the timer counter, it is difficult to grasp the timing when the value of the jackpot random number counter C1 becomes the winning value. Therefore, fraudulent acts using a “hanging board” or the like can be suppressed. In this case, any of the irregular delay circuits 602 of the fifth to eleventh embodiments may be applied. Note that the initial value information used as the initial value may be a parameter that varies according to the period from the output timing of the reset signal to the execution timing of the initial value setting process.

  (45) In the twelfth embodiment, the counter update circuit 701 having the jackpot random number counter C1 and the initial value random number counter CF is provided. However, the present invention is not limited to this, and the counter update having the initial value random number counter CF is performed. The circuit 701 is provided, and the jackpot random number counter C1 may be provided as part of the RAM 316. In this case, it is preferable that the value of the initial value random number counter CF is constantly updated. The value of the jackpot random number counter C1 is updated when the MPU 311 is operating, and when the initial value setting process is executed or when the value of the jackpot random number counter C1 has made one round, the counter update circuit The initial value random number counter CF 701 may be set to be read. Even in this configuration, the same effects as those of the twelfth embodiment can be obtained, and the configuration of the counter update circuit 701 can be simplified.

  The jackpot random number counter C1 and the initial value random number counter CF may be provided as part of the RAM 316. In this case, the value of the initial value random number counter CF is updated in a situation where the MPU 311 is operating, and is held in a situation where the MPU 311 is not operating. It is preferable that the initial value random number counter CF is excluded from the target of conversion. As a result, the value of the initial value random number counter CF is not affected by the initialization process and fluctuates in accordance with the timing at which the MPU 311 stops operating. Therefore, the initial value of the jackpot random number counter C1 after the initialization process is changed. Value fluctuations are ensured.

  (46) In the thirteenth embodiment, the RAM data initialization processing execution timing is delayed by the irregular delay circuit 602 with respect to the output timing of the RAM erase signal. The RAM erase signal output timing of the RAM erase signal output circuit 802 may be delayed by the irregular delay circuit 602 with respect to the operation timing of the RAM erase switch 801 during power-on. Specifically, an operation signal output circuit that outputs a signal to that effect when the RAM erasing switch 801 is turned on is provided, and the RAM erasure signal output circuit 802 indicates that the operation signal has been input. Based on this, the RAM erase signal is output. In such a configuration, an irregular delay circuit 602 is provided on a path connecting the operation signal output circuit and the RAM erase signal output circuit 802. Even in this case, the same effect as that of the thirteenth embodiment can be obtained. In this case, an irregular delay circuit 602 may be provided between the operation signal output circuit and the RAM erase signal output circuit 802 and between the RAM erase signal output circuit 802 and the MPU 311.

  Alternatively, the random erase circuit 602 may be mounted on the RAM erase signal output circuit 802 so that the random erase circuit 602 delays the output timing of the RAM erase signal with respect to the input timing of the operation signal. In short, the period from when the RAM erasing switch 801 is turned on until the RAM data is initialized may be changed.

  (47) In the fifth to eleventh embodiments, the value of the jackpot random number counter C1 is updated when the pachinko machine 10 is in the power-on state, and is not updated when the pachinko machine 10 is in the power-off state. Although it was set as the structure, it is not restricted to this, It is good also as a structure which the value of the jackpot random number counter C1 updates even in a power-off state.

  (48) In the fifth to twelfth embodiments described above, the hardware of the irregular delay circuit 602 that varies the operation start timing of the MPU 311 with respect to the output timing of the reset signal is provided. However, the present invention is not limited to this. The timing at which the value of the jackpot random number counter C1 becomes the winning value in the software processing may be changed. For example, a waveform grasping circuit for grasping the AC waveform from the commercial power supply is provided, and a process for grasping the waveform by the waveform grasping circuit is provided after the process of initializing the RAM in step S409 of the main process (FIG. 19) of the MPU 311. Further, when the AC waveform exceeds a predetermined threshold value, a process for setting the interrupt permission may be executed. In this case, it is preferable to provide a changing means for changing the predetermined threshold value. Even in such a configuration, it is possible to make it difficult to grasp the timing at which the big hit random number counter C1 starts updating. In short, it is only necessary to change the execution timing of at least one process in the middle of a plurality of processes until the value of the jackpot random number counter C1 becomes a winning value after the pachinko machine 10 is turned on. The specific contents of the process for changing the timing are arbitrary, and the changing means is not limited to hardware but may be software.

  (49) The reset signal output timing in the fifth to twelfth embodiments, the RAM erase signal output timing in the thirteenth to fourteenth embodiments, the operation voltage Vcc application timing in the fifteenth embodiment, In the seventeenth embodiment, the update start timing of the jackpot random number counter C1 with respect to the output timing of the data erasure signal is varied. Any configuration that varies the start timing may be used.

  (50) In the fifteenth and sixteenth embodiments described above, the counter value of the jackpot random number counter C1 is not held when the pachinko machine 10 is in a power interruption state, and the pachinko machine 10 Although it is configured to be reset to a predetermined value when it is in the on state, the present invention is not limited to this, and when the pachinko machine 10 is in a power interruption state, the counter value of the big hit random number counter C1 at that time is held It is good also as a structure. In this case, in the start-up process executed when the pachinko machine 10 is turned on, the value of the jackpot random number counter C1 may be excluded from the reset target. Thereby, since the counter value of the jackpot random number counter C1 when the pachinko machine 10 is in the power-on state is not easily grasped, it is possible to more appropriately suppress an illegal act using a “hanging board” or the like.

  As a specific configuration for realizing the above configuration, a flash memory is provided in at least a part of the ROM 315, an update program for the flash memory is provided, and the jackpot random number counter C1 is updated using the flash memory. A configuration to execute is conceivable.

  (51) In the fifteenth and sixteenth embodiments described above, the jackpot random number counter C1 is provided in the ROM 315. However, the present invention is not limited to this, and may be provided in the RAM 316. In this case, it is necessary to set so that the circuit that updates the jackpot random number counter C1 is not synchronized with the system clock signal. In such a configuration, when the pachinko machine 10 is in the power-off state, the backup power is supplied to the RAM 316 so as to hold the counter value of the jackpot random number counter C1, and the start is executed when the pachinko machine 10 is in the power-on state. In the raising process, the value of the jackpot random number counter C1 may be excluded from the reset target.

  (52) In the seventeenth embodiment, the clock signal transmission circuit 1101 is provided on the path connecting the hard random number clock circuit 900 and the MPU 311. However, the present invention is not limited to this. For example, as shown in FIG. The system clock circuit 312 and the MPU 311 may be connected via the two signal lines LN9 and LN10, and the clock signal transmission circuit 1101 may be provided only on one signal line LN10. In this case, a signal line LN11 for connecting the system clock circuit 312 and the clock signal transmission circuit 1101 is provided separately from the signal line LN10, and the system clock circuit 312 is provided for each of the three signal lines LN9, LN10, and LN11. The clock signal is output. According to this configuration, the clock signal input to the MPU 311 via the signal line LN9 not provided with the clock signal transmission circuit 1101 is used as the system clock signal, and the signal line LN10 in which the clock signal transmission circuit 1101 is disposed. By using the clock signal input to the MPU 311 via the hard random number clock signal, the configuration can be simplified without hindering the progress of the game.

  In particular, in the configuration for obtaining the hard random number clock signal by converting the system clock signal, the power line connecting the system clock circuit 312 and the power interruption monitoring board 302 is shown in the fifteenth or sixteenth embodiment. If the power transmission circuit 901 is provided, the input of the system clock signal to the MPU 311 is also delayed, which may hinder the progress of the game. On the other hand, with the above configuration, only the input of the update clock signal to the MPU 311 is irregularly delayed, while the input of the game clock signal to the MPU 311 is not delayed. That is, the inconvenience caused by the configuration of obtaining the hard random number clock signal by converting the system clock signal is avoided.

  However, in this case, since the cycle of the system clock signal and the cycle of the hard random number clock signal are the same, the cycle of the update timing of the jackpot random number counter C1 can be grasped by grasping the cycle of the system clock signal. There is a case. For this, the clock signal transmission circuit 1101 may be provided with a circuit for modulating the period of the clock signal.

  (53) In the seventeenth embodiment, the clock signal is input to the gate of the thyristor 1102. However, the present invention is not limited to this, and a constant HI level signal may be output. Even in such a configuration, the period from the output timing of the hard random number clock signal from the hard random number clock circuit 900 to the input timing of the signal to the MPU 311 becomes irregular. As a configuration for outputting a constant HI level signal, a circuit for converting the hard random number clock signal into the HI level signal on the signal line LN8 connecting the hard random number clock circuit 900 and the irregular delay circuit 602 is provided. The structure to provide can be considered.

  Further, the clock signal transmission circuit 1101 is not limited to the thyristor 1102, for example, the hard random number clock circuit 900 and the MPU 311 are connected, and a switch (for example, a piezo element) is provided on a signal line for transmitting the hard random number clock signal. When an operation signal delayed from the irregular delay circuit 602 is input, the switch may be set to be turned on. However, the seventeenth embodiment is superior in that a clock signal having a plurality of types of output intervals is output.

  Furthermore, in the seventeenth embodiment, the irregular delay circuit 602 used in the fifth embodiment is used. However, the present invention is not limited to this, and any configuration of the sixth to eleventh embodiments may be applied. .

  (54) In the fifteenth and sixteenth embodiments, the transistors 913 and 914 of the amplifier circuit 912 are provided with the bypass wiring for connecting the gate and the emitter, and the resistors 913b and 914b. It is good also as a structure which omits. In this case, since the amplification factor of each of the transistors 913 and 914 is improved, the operating voltage Vcc can be lowered while securing the operating power of the hard random number clock circuit 900. However, from the viewpoint of circuit stability, the fifteenth and sixteenth embodiments are superior.

  (55) In the fifteenth and sixteenth embodiments, the amplifier circuit 912 is provided. However, the present invention is not limited to this, and the power supply and launch control board 321 and the hard random number clock circuit 900 are not provided without the amplifier circuit 912. An irregular delay circuit 602 may be provided on a path connecting the two and the output of the AND circuit 916 directly to the hard random number clock circuit 900. In this case, the operating voltage Vcc needs to be high and the resistance value of the adjustment resistor 911 needs to be changed. However, the configuration in which the amplifier circuit 912 is provided is superior from the viewpoint of circuit loss and circuit deterioration.

  In addition, although the NPN transistor 913 and the PNP transistor 914 are connected in an inverted Darlington connection, the present invention is not limited to this, and any structure that amplifies the output current from the irregular delay circuit 602 may be used. For example, two NPN transistors may be connected by Darlington connection. In this case, the amplifier circuit 912 operates more stably than in the case of inverted Darlington connection. However, the inverted Darlington connection is superior from the viewpoint of lowering the operating voltage Vcc because the loss voltage in the amplifier circuit 912 is smaller.

  (56) In the fifteenth and sixteenth embodiments, the D flip-flop 915 is used as the irregular delay circuit 602. However, the present invention is not limited to this, and any of the fifth to eleventh embodiments may be used. . In this case, the NAND circuit 612 is replaced with an AND circuit 916.

  Further, the AND circuit 916 is not necessarily provided. Even in this case, when the application of the operating voltage Vcc from the power source and the launch control board 321 is stopped, the application of the voltage between the collector and the emitter of the amplifier circuit 912 is stopped, so that the operation to the hard random number clock circuit 900 is performed. The power supply stops. Thereby, simplification of a structure can be achieved. However, from the viewpoint of preventing malfunction of the amplifier circuit 912, the configuration in which the AND circuit 916 is provided is superior.

  (57) In the sixteenth embodiment, the power transmission circuit 901 is provided with the irregular delay circuit 602. However, the present invention is not limited to this. For example, a path connecting the data erasure signal output circuit 1002 and the reset transistor 1003 A configuration in which the irregular delay circuit 602 is provided thereover may be employed. In this case, the timing at which the HI level signal is input to the power transfer circuit 901 is irregularly delayed with respect to the timing at which the output of the HI level signal from the data erase signal output circuit 1002 is resumed. That is, the target of irregular delay is “a period from the output timing of the HI level signal from the data erasure signal output circuit 1002 to the input timing of the HI level signal to the power transfer circuit 901”. As a result, the operation power supply start timing to the hard random number clock circuit 900 is irregularly delayed with respect to the operation timing of the data erasure switch 1001. Therefore, since it is difficult to specify the output timing of the hard random number clock signal from the operation timing of the data erasure switch 1001, it is difficult to grasp the update timing of the jackpot random number counter C1. Therefore, fraudulent acts using the “hanging board” or the like can be suppressed.

  (58) In the sixteenth embodiment, the specific stop period Ts is a predetermined period. However, the specific stop period Ts is not limited to this, and the specific stop period Ts may be changed. According to such a configuration, the irregular delay circuit 602 can be omitted from the power transmission circuit 901, and thus the configuration can be simplified. However, the specific stop period Ts is preferably at least longer than the period T3 of the pulse signal output from the Schmitt trigger 413. If the specific stop period Ts is changed under such conditions, the range of the variable period may be narrowed. In addition to this, the configuration becomes complicated. In view of these points, the sixteenth embodiment is preferable.

  As a specific configuration for changing the specific stop period Ts, a configuration using an integration circuit of a monostable multivibrator is conceivable.

  (59) In the above sixteenth embodiment, the specific stop period Ts is set to be longer than at least the period T3 of the pulse signal output from the Schmitt trigger 413. However, the present invention is not limited to this, for example, the clear terminal of the D flip-flop 915 The D flip-flop 915 may be reset using In this case, the clear terminal and the data erasure signal output circuit 1002 are electrically connected. According to such a configuration, the D flip-flop 915 is reset and a LOW level signal is output from the Q terminal when the LOW level signal is input from the data erasure signal output circuit 1002 to the clear terminal. Thereby, the D flip-flop 915 can be surely reset. Therefore, the specific stop period Ts can be omitted. Furthermore, in this case, the D flip-flop 915 can be reset without waiting for the input of the pulse signal, so that the AND circuit 916 can be omitted.

  (60) In the sixteenth embodiment, the reset transistor 1003 is provided, and the data erasure signal output circuit 1002 outputs the HI level signal to the gate of the reset transistor 1003 in the situation where the pachinko machine 10 is in the power-on state. , And when the data erasure switch 1001 is operated, the LOW level signal is once output and then the HI level signal is output again. However, the present invention is not limited to this. For example, instead of the reset transistor 1003 Alternatively, an inverter circuit (inverting circuit) may be provided, and the input terminal of the inverter circuit and the data erasure signal output circuit 1002 may be electrically connected. In this case, the data erasure signal output circuit 1002 outputs a LOW level signal to the inverter circuit in a situation where the pachinko machine 10 is in a power-on state, and when the data erasure switch 1001 is operated, the Schmitt trigger A one-shot pulse having a pulse width larger than the period T3 of the pulse signal output from 413 may be output.

  According to such a configuration, the inverter circuit outputs the HI level signal (operating voltage) to the irregular delay circuit 602 and the amplifier circuit 912 in a situation where the LOW level signal is input from the data erasure signal output circuit 1002. On the other hand, when the HI level signal is input from the data erasure signal output circuit 1002, the LOW level signal is output to the irregular delay circuit 602 and the amplifier circuit 912. Then, a LOW level signal is output to the irregular delay circuit 602 and the amplifier circuit 912 based on the input of the one-shot pulse. In this case, no voltage is applied between the collector and emitter of the PNP transistor 914 of the amplifier circuit 912, and a LOW level signal is output from the irregular delay circuit 602 to the amplifier circuit 912. Stops. As a result, the supply of operating power to the hard random number clock circuit 900 is temporarily stopped.

  Here, since the pulse width of the one-shot pulse is set to be larger than the cycle T3 of the pulse signal output from the Schmitt trigger 413, at least once in the state where the one-shot pulse is input, the D flip-flop 915 is synchronized. In this case, since the LOW level signal is input to the D terminal, the LOW level signal is output from the Q terminal, and the LOW level state is maintained.

  Thereafter, when the input of the one-shot pulse is completed (the input signal is changed from the HI level to the LOW level), the HI level signal (operating voltage) is output to the irregular delay circuit 602 and the amplifier circuit 912. Accordingly, the supply of operating power to the hard random number clock circuit 900 is resumed. In this case, the supply start timing of the operating power to the hard random number clock circuit 900 is irregularly delayed by the irregular delay circuit 602 with respect to the timing when the input of the one-shot pulse is completed. Therefore, the same effects as those in the sixteenth embodiment can be obtained.

  The inverter circuit is arbitrary such as an inverter circuit composed of an NPN transistor or a CMOS inverter circuit.

  (61) In the sixteenth embodiment, the reset transistor 1003 may be provided only on the path connecting the irregular delay circuit 602 and the power supply and launch control board 321. In this case, the voltage applied to the amplifier circuit 912 is higher by the voltage drop due to the reset transistor 1003 than in the sixteenth embodiment, so that the circuit loss is reduced and the operating voltage Vcc is lowered. Can be achieved. Even in this case, when a LOW level signal is output from the data erasure signal output circuit 1002, the LOW level signal is immediately input to one input terminal of the AND circuit 916. The power supply to the clock circuit 900 is immediately stopped. Therefore, a quick shutdown is ensured. However, from the viewpoint of preventing malfunction of the amplifier circuit 912, the sixteenth embodiment is superior.

  (62) In the fifteenth embodiment, the hard random number clock circuit 900 is configured to output the hard random number clock signal when supplied with operating power. However, the present invention is not limited to this. For example, the reset circuit 601 And the hard random number clock circuit 900 are connected to the hard random number clock circuit 900 when the operating power is supplied and the reset signal is input from the reset circuit 601. It may be configured to output a random number clock signal. In this case, an irregular delay circuit 602 may be provided on a path connecting the hard random number clock circuit 900 and the reset circuit 601.

  (63) Other types of pachinko machines different from the above-described embodiments, such as pachinko machines that release a predetermined number of times when a game ball enters a specific area of a special device, or game balls in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a right if a player enters, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. Or, if a specific symbol or a combination of specific symbols is established on the active line visible from the display window after the reel has stopped after a predetermined period of time, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  In addition, a pachinko machine and a slot machine that have a take-in device and start rotation of a reel by operating a start lever after a predetermined number of game balls stored in the storage unit are taken in by the take-in device The present invention can also be applied to a gaming machine in which is integrated.

  According to the feature A2, the update clock signal is obtained by converting the game clock signal. This eliminates the need for a configuration for outputting a clock signal, and thus simplifies the configuration.

  In addition, since the game clock signal is input through the first signal path, control related to the game is performed at a constant timing regardless of the mode of the update clock signal. This makes it possible to change the mode of the update clock signal without affecting the control related to the game.

Therefore, the effect shown in the feature A2 can be obtained.

  Note that the configuration limited in any one of the features C1 to C10 may be applied to the configuration of this feature. In this case, the further effect by having applied each structure can be show | played.

  Each invention of the above-mentioned feature group A is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Here, the pachinko machine has a storage element such as a memory in which a control program relating to a game is stored, an arithmetic element that executes the control program, or a control board on which an MPU in which these are integrated is mounted. What is provided is known. In the pachinko machine, a series of games are controlled by an arithmetic element.

  In the above gaming machine, an oscillation circuit that outputs a clock signal that is a reference for the operation timing of the arithmetic element is provided. The arithmetic element executes the control program by operating a plurality of elements in synchronization with the input of the clock signal output from the oscillation circuit. As a control program, for example, the counter is periodically updated within a predetermined numerical range, and when a game ball enters the operation port, the value of the counter at that time is acquired, When the value matches a predetermined winning value such as “7”, for example, the gaming state may be shifted to the jackpot state.

  Here, by grasping the update timing of the counter used in the jackpot lottery, the timing at which the value of the counter becomes the jackpot winning value may be grasped. Then, in accordance with the timing, an illegal act that intentionally generates a jackpot by outputting an illegal signal to a regular control board can be considered.

  It should be noted that various misconducts are assumed in gaming machines, and as described above, the act of grasping the predetermined processing timing and the like in the control main body and performing the cheating based on the grasp result is not limited to that related to the jackpot lottery. . Such fraudulent acts are not limited to pachinko machines, but are also the same in slot machines.

The gaming machine according to claim 1, wherein the numerical information update means updates the numerical information based on the input of the update clock signal from the update signal output means.

  According to the feature B1, the progression of the game is controlled based on the game clock signal being input to the control means, and the numerical value is based on the update clock signal being input to the numerical information update means. Information is updated. Thus, for example, by changing the cycle of the update clock signal, the degree of freedom in setting the update timing of the numerical information can be increased without affecting the progress of the game.

  In addition, for example, by changing the period of the update clock signal from the period of the game clock signal, even when the period of the game clock signal is grasped, the update timing of the numerical information is grasped from the period. Hateful. Therefore, grasp the update timing of numerical information from the cycle of the gaming clock signal, and establish the acquisition condition illegally according to the timing when the numerical information becomes the specific information, and suppress the fraudulent act that deliberately generates the specific state Can do.

An acquisition unit (a function of executing the processes of steps S305 and S307 in the MPU 311) that acquires the numerical information from the numerical information update unit when a predetermined acquisition condition is satisfied;
With
In the gaming machine that enters a specific state based on the fact that the numerical information acquired by the acquisition unit corresponds to predetermined specific information,
Provided separately from the game signal output means, and provided with an update signal output means (hard random number clock circuit 313) for outputting an update clock signal,
The gaming machine according to claim 1, wherein the numerical information updating means sequentially updates the numerical information based on the input of the update clock signal.

  According to the feature B2, the progress of the game is controlled based on the input of the game clock signal, and the numerical information is based on the input of the update clock signal different from the game clock signal. Updated. Thus, the frequency can be set individually for the game clock signal and the update clock signal. Therefore, it is possible to increase the degree of freedom in setting the update timing of numerical information without affecting the progress of the game.

  Further, for example, even when the period of the gaming clock signal is grasped by setting the gaming clock signal and the updating clock signal to have different periods, the update timing of the numerical information is determined from the period. Difficult to grasp. Therefore, grasp the update timing of numerical information from the cycle of the gaming clock signal, and establish the acquisition condition illegally according to the timing when the numerical information becomes the specific information, and suppress the fraudulent act that deliberately generates the specific state Can do.

  As described above, in the gaming machine in which the game is controlled based on the input of the clock signal, the control system can be made suitable.

  Feature B3. The game machine according to claim B2, wherein the update signal output means outputs the update clock signal so as not to synchronize with the game clock signal.

  According to the feature B3, since the update clock signal is not synchronized with the game clock signal, it is difficult to grasp the output timing of the update clock signal from the output timing of the game clock signal. Yes. Thereby, it is possible to suppress an illegal act of grasping the update timing of the numerical information by the numerical information update means from the output timing of the gaming clock signal.

Feature B4. The numerical information update means is to update the numerical information with a predetermined location from a rising edge to a falling edge in the update clock signal as a trigger,
The update signal output means outputs the update clock signal so that an output interval of a signal state corresponding to the trigger is different from the game clock signal. The feature B2 or B3 is characterized in that The gaming machine described.

  According to the feature B4, the game clock signal and the update clock signal are different in the output interval of the signal state that triggers the update of the numerical information, so even if the game clock signal is grasped The update timing of numerical information is difficult to grasp. Thereby, the update timing of numerical information can be specified from the gaming clock signal, and an illegal act of specifying the timing when the numerical information becomes the specific information can be suppressed.

  Feature B5. The update signal output means includes signal conversion means (signal conversion circuit 402) for generating the update clock signal by converting an AC voltage supplied from an external power source into a pulse signal. The gaming machine according to any one of features B2 to B4.

  According to the feature B5, the update clock signal is obtained by converting an AC voltage supplied from an external power source into a pulse signal. Thus, for example, by using a commercial power supply or a game machine power supply as an external power supply, a pulse signal can be easily obtained, and the pulse signal can be used as an update clock signal. Therefore, the configuration can be simplified.

Feature B6. The numerical information update means is to update the numerical information with a predetermined location from a rising edge to a falling edge in the update clock signal as a trigger,
The signal conversion means includes output interval conversion means (frequency conversion circuit 401) for converting the output interval of the signal state corresponding to the trigger so as not to correspond to the cycle of the input AC voltage. A gaming machine according to Feature B5, characterized in that

  According to the feature B6, the output interval of the signal state corresponding to the trigger for updating the numerical information is converted so as not to correspond to the interval of the input AC voltage. Thereby, even if the period of the alternating voltage input is specified, the output interval of the signal state corresponding to the update trigger of numerical information is difficult to specify. Therefore, it is possible to identify the output interval of the signal state corresponding to the trigger for updating the numerical information from the frequency of the input AC voltage, and to suppress the illegal act of specifying the update timing of the numerical information.

  As a more specific configuration of the output interval conversion means, “the output interval conversion means uses the frequency of the update clock signal output from the update signal output means as the frequency of the input AC voltage. Can be converted to have different frequencies. "

Feature B7. The numerical information update means is to update the numerical information with a predetermined location from a rising edge to a falling edge in the update clock signal as a trigger,
The signal converter generates an update clock signal having a predetermined specific frequency regardless of whether the frequency of the input AC voltage is the first frequency or the second frequency. The gaming machine according to Feature B5 or Feature B6.

  For example, when a commercial power supply is used as the external power supply, the frequency of the AC clock voltage is different between East Japan and West Japan, so the frequency of the update clock signal is also different. Then, since the output interval of the signal state corresponding to the trigger for updating the numerical information is different, the update frequency of the numerical information is different in the area of use, and the fairness of the game is hindered.

  On the other hand, according to this feature, the frequency of the update clock signal is a specific frequency regardless of whether the frequency of the input AC voltage is the first frequency or the second frequency. Thereby, since the output interval of the signal state corresponding to the trigger for updating the numerical information does not depend on the frequency of the AC voltage, the above inconvenience can be avoided.

  Note that the first frequency and the second frequency may be 50 Hz and 60 Hz, which are frequencies of the commercial power supply.

Feature B8. The control means includes
Initial value information updating means for sequentially updating the initial value information within the numerical value range (a function of updating the random number initial value counter CINI or the pulse shift counter SC in the MPU 311) at each update timing;
Determination means for determining whether or not the numerical information has made one round (function to execute the process of step S605 in the MPU 311);
An initial value information acquisition unit (a function of executing the process of step S606 in the MPU 311) that acquires the initial value information from the initial value information update unit when the determination unit determines that the numerical information has made one round; ,
When the initial value information is acquired, writing means for writing the acquired initial value information as the initial value of the numerical information (function to execute the process of step S606 in the MPU 311);
A prohibition unit (a function for executing the processes of steps S603 and S607 in the MPU 311) for prohibiting the update of the numerical information over a period during writing by the writing unit;
The gaming machine according to any one of features B2 to B7, comprising:

  According to the feature B8, when the numerical information makes one round, the initial value information is acquired, and updating of the numerical information is started from the initial value information. Thereby, since the initial value of the numerical information changes every time the numerical information makes one round, it is difficult to specify the timing at which the numerical information becomes the specific information.

  Here, the update of the numerical information and the control by the control means are different in the clock signal that triggers the execution thereof, so the numerical information may be updated during the writing by the writing means. In particular, when the game clock signal and the update clock signal are not synchronized with each other, the control by the control means and the update by the numerical information update means are not synchronized. Thereby, the numerical information is easily updated during writing. As a result, the consistency of contents cannot be obtained, and inconveniences such as errors are likely to occur. In this regard, according to this feature, updating of numerical information is prohibited during writing. Thereby, the said inconvenience can be avoided.

  Further, in relation to the feature B6, “the control means periodically performs determination processing by the determination means at a predetermined cycle, and the output interval of the signal state corresponding to the trigger is determined by the determination means. It is good to set it to be longer than the execution cycle. As a result, since the determination process is performed at least once between the update of the numerical information and the next update, it is possible to reliably grasp that the numerical information has made one revolution and the numerical information has made one revolution. The state does not continue excessively.

Feature B9. A substrate box (substrate box 163) for accommodating the numerical information updating means;
Fixing means (sealing portion 164) for fixing the substrate box in a state where it cannot be opened or difficult to open;
With
The gaming machine according to any one of features B2 to B8, wherein at least the update signal output means is housed in the board box.

  According to the feature B9, at least the update signal output means and the numerical information update means are accommodated in the board box. The substrate box is fixed in a state where it cannot be opened or difficult to open by a fixing means. Thereby, it is possible to prevent an illegal act against the numerical information updating means and an illegal act against the update signal output means. Therefore, it is possible to suitably suppress an illegal act against the update signal output means such as grasping the cycle of the update clock signal while simplifying the configuration.

  Further, regarding the relationship with the feature B6, it is preferable that “the output interval conversion means is accommodated in the substrate box”. Thereby, the fraudulent act with respect to an output space | interval conversion means can be suppressed. Therefore, it is possible to identify the output interval of the signal state corresponding to the update trigger of the numerical information based on the analysis of the output interval conversion means, and to suppress an illegal act of grasping the update timing of the numerical information.

Feature B10. The numerical information update means is to update the numerical information with a predetermined location from a rising edge to a falling edge in the update clock signal as a trigger,
A signal path connecting the update signal output means and the numerical information update means;
Fluctuation means (modulation circuit 314) that is provided in the middle of the signal path and varies the trigger interval from one trigger to the next trigger;
The gaming machine according to any one of features B2 to B9, comprising:

  According to the feature B10, since the interval between triggers that trigger the update of the numerical information varies, the update interval of the numerical information varies. Thereby, since the update timing of numerical information is difficult to grasp, the timing at which the numerical information becomes specific information is difficult to be specified. Therefore, for example, the acquisition condition can be established illegally at the timing when the numerical information becomes the specific information, and an illegal act that intentionally generates the specific state can be suppressed.

  Further, according to the trigger interval, the period in which the numerical information becomes the specific information and the period in which the numerical information makes a round may vary. Accordingly, for example, by adjusting the trigger interval, it is possible to adjust the substantial winning probability derived from the ratio of the period in which the numerical information becomes the specific information with respect to the period in which the numerical information makes one round. Therefore, since the substantial winning probability can be made lower than the numerical range of the numerical information and the theoretical winning probability derived from the specific information, the numerical range of the numerical information can be reduced. Therefore, the capacity required for numerical information can be reduced.

  As described above, the numerical information can be updated well.

  Note that the configuration limited in any one of the features C1 to C10 may be applied to the configuration of this feature. In this case, the further effect by having applied each structure can be show | played.

Feature B11. Output means (system clock circuit 312) for outputting a clock signal;
A control means for controlling the progress of the game by executing a plurality of processes based on the clock signal output from the output means (a function for executing a process related to the progress of the game in the MPU 311);
In gaming machines equipped with
The control means has a configuration in which a first clock signal is input through a first signal path and a second clock signal is input through a second signal path, and the first clock signal is First processing means for executing a first process among the plurality of processes based on the input, and executing a second process among the plurality of processes based on the input of the second clock signal. And a second processing means.

  According to the feature B11, the first process is executed based on the input of the first clock signal, and the second process is executed based on the input of the second clock signal. Thereby, by setting the frequency separately for the first clock signal and the second clock signal, it is possible to increase the degree of freedom in setting the execution timing of each of the first process and the second process.

  In this case, the first clock signal and the second clock signal may be set to have different periods. Thus, for example, the first process is a process that is particularly likely to be a target of fraud among a plurality of processes, and the second process is a process that is a target other than the first process among the plurality of processes. Since it is difficult to specify the execution timing, it is possible to suppress an illegal act on a process that is likely to be an object of an illegal act.

  Each invention of the above-mentioned feature group B is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Here, the pachinko machine is provided with a storage element such as a memory in which a control program related to the game is stored, a calculation element that executes the control program, or a control board on which an MPU in which these are integrated is mounted. What is known is known. The pachinko machine has a series of games controlled by a control program.

  In the above gaming machine, an oscillation circuit that outputs a clock signal that is a reference for the operation timing of the arithmetic element is provided. The arithmetic element executes the control program by operating a plurality of elements in synchronization with the input of the clock signal output from the oscillation circuit. As the control program, for example, the counter is periodically updated within a predetermined numerical range, and when the game ball enters the operation port, the value of the counter at that time is acquired, and the counter If the value of the game matches a predetermined winning value such as “7”, for example, the gaming state may be shifted to the jackpot state.

  Here, depending on the purpose of processing, it may be preferable to change the frequency of the clock signal. However, changing the frequency of the clock signal may affect other processes, which is not preferable.

  Also, for example, a fraudulent act in which a fraudulent circuit is connected to the path connecting the arithmetic element and the oscillation circuit, and a fraudulent state is intentionally generated in synchronization with the clock signal output from the oscillation circuit. May be performed.

  As described above, there is still room for improvement in the control system including the oscillation circuit that outputs the clock signal and the arithmetic element that controls the game based on the input of the clock signal.

  Note that the above problem is a common problem in gaming machines that include an oscillation circuit that outputs a clock signal and an arithmetic element that executes a control program related to a game based on the input of the clock signal.

Feature C1. Numerical information updating means (counter circuit 317) for sequentially updating numerical information within a predetermined numerical range at each update timing;
An acquisition unit (a function of executing the processes of steps S305 and S307 in the MPU 311) that acquires the numerical information from the numerical information update unit when a predetermined acquisition condition is satisfied;
With
In the gaming machine that is in a specific state based on the numerical information acquired by the acquisition means corresponding to predetermined specific information,
A gaming machine comprising a changing means (modulation circuit 314) for changing an interval of updating from one numerical information to the next numerical information.

  According to the feature C1, since the update interval varies, it is difficult to grasp the update timing of the numerical information. Thereby, it is difficult to specify the timing at which the numerical information becomes the specific information. Therefore, for example, the acquisition condition can be established illegally at the timing when the numerical information becomes the specific information, and an illegal act that intentionally generates the specific state can be suppressed.

  Further, according to the change of the update interval, the period in which the numerical information is the specific information and the period required for the numerical information to make one round may change. Accordingly, for example, by adjusting the update interval, it is possible to adjust the substantial winning probability derived from the ratio of the period in which the numerical information is the specific information with respect to the period required for the numerical information to make one round. Therefore, by changing the update interval, the substantial winning probability can be made lower than the theoretical winning probability derived from the numerical range of the numerical information and the specific information. Therefore, since the numerical range of numerical information can be reduced, the capacity required for numerical information can be reduced.

  As described above, the numerical information can be updated well.

  Feature C2. The game machine according to Feature C1, wherein the changing means changes a period required for the numerical information to make one round in response to the numerical information making a round.

  According to the feature C2, since the period required for the numerical information to make one revolution varies as the numerical information makes one revolution, it is difficult to specify the timing at which the numerical information becomes the initial value. This makes it difficult to specify the timing at which the numerical information becomes the specific information from the timing at which the numerical information becomes the initial value. Therefore, the acquisition condition can be established illegally in accordance with the timing when the numerical information becomes the specific information, and an illegal act that intentionally generates the specific state can be suppressed.

  Feature C3. The changing means changes the interval at which the numerical information is updated from one numerical information to the next numerical information, so that a period required for the numerical information to make one round sequentially changes to one of a plurality of types of periods. In addition, the gaming machine according to the feature C2, wherein the unit period having the plurality of types of periods is repeated every plurality of rounds of the numerical information.

  According to the feature C3, since the period required for the numerical information to make one round sequentially changes to one of a plurality of types of periods, the numerical information makes one round in response to the numerical information making one round. The time required varies. Thereby, the effect of the feature C2 is produced.

  Here, if the period required for the numerical information to make one round fluctuates, the substantial winning probability fluctuates. For this reason, if the period required for one round of numerical information is irregular from the viewpoint of fraud prevention, the range in which the actual winning probability fluctuates becomes wide, so the fairness of the game and the management of the game hall It is not preferable from the viewpoint of ease.

  On the other hand, according to this feature, a unit period having a plurality of types of periods is repeated for each of a plurality of rounds of numerical information. It becomes the average of the actual winning probability corresponding to each. As a result, every time the numerical information makes one round, the period required for the numerical information to make one round and the substantial winning probability change, while the overall substantial winning probability becomes a constant probability. Yes. Therefore, it is difficult to specify the timing when the numerical information becomes the specific information, and the stability of the game and the ease of management of the game hall are ensured.

  Feature C4. The change means changes the update timing so that the numerical information is updated at a plurality of types of update intervals within the numerical value range, according to any one of the features C1 to C3, Game machines.

  According to the feature C4, since the numerical information is updated at plural types of update intervals within the numerical value range, the update timing of the numerical information varies. This makes it difficult to specify the update timing of the numerical information, and it becomes difficult to specify the timing at which the numerical information becomes the specific information. Therefore, it is possible to suppress an illegal act that intentionally generates the specific state by illegally establishing the acquisition condition in accordance with the timing at which the numerical information becomes the specific information.

  Feature C5. The variation means is configured to vary a period in which the numerical information is the specific information in response to one round of the numerical information, according to any one of the features C1 to C4 Game machines.

  According to the feature C5, the period during which the numerical information is the specific information varies as the numerical information goes around once. Thereby, it is possible to make it difficult to specify the period in which the numerical information is the specific information. Therefore, it is possible to suppress an illegal act that illegally establishes the acquisition condition in accordance with the timing when the numerical information is the specific information.

  Feature C6. The fluctuating means causes the period in which the numerical information is the specific information to sequentially transition to any one of a plurality of types of periods, and for the unit period required for the numerical information to go around a specific plurality of periods. The gaming machine according to Feature C5, wherein the ratio of the period in which the numerical information is specific information is the same or substantially the same for each unit period.

  According to the feature C6, the period in which the numerical information is the specific information is sequentially shifted to one of a plurality of types of periods. As a result, the period during which the numerical information is the specific information fluctuates as the numerical information makes one revolution, so that the effect of the feature C5 is achieved.

  Here, if the period in which the numerical information is the specific information varies, the substantial winning probability varies. For this reason, if the period in which numerical information is specified information is irregular from the viewpoint of fraud prevention, the range in which the actual winning probability fluctuates becomes wide. It is not preferable from the viewpoint of ease.

  On the other hand, according to this feature, the ratio of the period in which the numerical information is the specific information with respect to the unit period required for the numerical information to make a specific number of rounds is the same or substantially the same for each unit period. . Thereby, if paying attention to the unit of the unit period, the substantial winning probability is the same or substantially the same. Therefore, every time the numerical information makes one round, the period in which the numerical information is the specific information and the actual winning probability fluctuate, while the overall actual winning probability is a constant probability. . Therefore, the stability of the game and the ease of management of the game hall are ensured while making it difficult to specify the period in which the numerical information is the specific information.

Feature C7. The numerical information updating means is configured of a plurality of update timings (pulse signals), and numerical information updating in accordance with an update group (pulse signal group) having a plurality of types of update intervals is repeated for each update group. And
The numerical value range and the update timing so that the number of terms (counter term number) of the numerical sequence composed of numerical values that can be taken by the numerical information does not become a multiple of the number of update timings (number of signals) included in the update group. The gaming machine according to any one of features C4 to C6, characterized in that is set.

  If the number of terms is a multiple of the number of update timings included in the update group (hereinafter simply referred to as update number) and the numerical information makes one round, update starts from a predetermined initial value. In the case of the configuration, while the update interval of the numerical information varies, the update timing corresponding to the update in which the numerical information becomes the initial value does not change in the update group. For this reason, the period from the timing when the numerical information becomes the initial value to the timing when it becomes the specific information is constant, and the period during which the numerical information is the specific information is constant.

  On the other hand, according to this feature, the numerical value range and the update timing of the numerical information are set so that the number of terms is not a multiple of the update number. Accordingly, even if the numerical information is sequentially updated from a predetermined fixed value every time the numerical information makes one round, the update timing corresponding to the update in which the numerical information becomes the initial value varies in the update group. . Thereby, the period from the timing when the numerical information becomes the initial value to the timing when it becomes the specific information varies, and the period during which the numerical information becomes the specific information varies. Therefore, it is difficult to specify these periods. Therefore, it is difficult to specify the timing when the numerical information is the specific information based on these periods.

  In addition, in the update group, the substantial winning probability changes according to the update timing corresponding to the update in which the numerical information becomes the initial value. Thereby, every time the numerical information makes one round, the substantial winning probability varies. On the other hand, the substantial winning probability as a whole is the average of the winning probability as a whole corresponding to each update timing, and thus does not vary. Thereby, the fairness of the game and the ease of management of the game hall are secured.

  The “number of terms” means “N + 1” when the numerical value range of the numerical information is “0 to N”, for example.

Feature C8. Initial value information updating means for sequentially updating the initial value information within a predetermined range (function of updating the random number initial value counter CINI or the pulse shift counter SC in the MPU 311);
An initial value information acquisition unit (a function of executing the process of step S606 in the MPU 311) that acquires the initial value information from the initial value information update unit when the numerical information makes one round;
With
When the initial value information is acquired, the numerical information update unit updates the numerical information from the acquired initial value information. If any one of the characteristics C1 to C7 is obtained, The gaming machine described.

  According to the feature C8, the initial value information of the initial value information update unit is acquired every time the numerical information makes one round, and the numerical information is updated from the acquired initial value information. The initial value information fluctuates according to the acquisition timing. Thereby, the period until numerical information becomes specific information changes. Therefore, it is difficult to specify the timing at which the numerical information becomes the specific information.

  Even if the number of terms is a multiple of the number of updates, the numerical value corresponding to the update timing fluctuates in the update group as the initial value fluctuates every time the numerical information makes one round. As a result, even if the number of terms is a multiple of the number of updates, the period from the timing when the initial value is updated to the timing when the numerical information becomes the specific information varies, so the numerical information is specified. Information timing is hard to be specified. Therefore, even if the number of terms is a multiple of the number of updates, it is difficult to specify the timing at which the numerical information becomes the specific information.

  Examples of “within a predetermined range” include “within the range of the number of update timings included in the update group” and “within the numerical range of the numerical information”.

Feature C9. The numerical information update means is configured to repeat the update of numerical information in accordance with an update group configured from a plurality of update timings and having a plurality of types of update intervals,
The numerical range and the update timing so that the number of terms (counter term number) of the numerical sequence composed of numerical values that can be taken by the numerical information is a multiple of the number of update timings (number of signals) included in the update group. Is set,
Further, the specific information and the update timing are set so that a period in which the numerical information is the specific information does not correspond to a maximum update interval among update intervals included in the update group. The gaming machine according to feature C1.

  According to the feature C9, since the number of terms is a multiple of the number of update timings included in the update group, the numerical information corresponding to the update timing is constant in the update group. Thereby, even if numerical information makes one round, the retention period of each numerical information does not change. In such a case, the period in which the numerical information is the specific information is set so as not to correspond to the maximum update interval in the update group. Thereby, the period in which the numerical information is the specific information can be made relatively shorter than the period in which the numerical information is other numerical information. Therefore, the substantial winning probability can be made smaller than the theoretical probability. Accordingly, it is possible to narrow the numerical range of numerical information necessary for setting a predetermined winning probability. Therefore, the capacity required for numerical information can be reduced.

  It is preferable that “the specific information and the update timing are set so that the period in which the numerical information is the specific information corresponds to the minimum update interval among the update intervals included in the update group”. .

Feature C10. An update signal output means (hard random number clock circuit 313) for outputting an update clock signal;
The numerical information update means is for updating the numerical information using a predetermined portion from a rising edge to a falling edge in the update clock signal as a trigger,
Any one of the features C1 to C9, wherein the changing means changes an interval between a trigger that triggers the update of one numerical information and a trigger that triggers the update of the next numerical information. The gaming machine described in 1.

  According to the feature C10, since the interval of the trigger that triggers the update of the numerical information is changed, the change of the update interval of the numerical information is realized. This eliminates the need for software processing for changing the update interval, thereby reducing the burden of software processing.

  Further, in relation to the feature C4, “the changing means changes at least one of the pulse width or the pulse interval of the update clock signal and outputs a pulse signal group including a plurality of pulse signals as one cycle. Thus, it is preferable that pulse signals are output at a plurality of types of trigger intervals. " In this case, for the feature C7 and the feature C9, “update group” is replaced with “pulse signal group” and “update timing” is replaced with “trigger”.

Feature C11. A game signal output means (system clock circuit 312) that is provided separately from the update signal output means and outputs a game clock signal;
Control means for performing control related to the game based on the input of the game clock signal (function to execute processing related to the progress of the game in the MPU 311);
The gaming machine according to Feature C10, further comprising:

  According to the feature C11, since the game control is performed based on a game clock signal different from the update clock signal, even if the input timing of the update clock signal varies, the influence of the variation The game is controlled without receiving the game. Thereby, the effect of feature C10 can be acquired, without affecting the control regarding a game.

  The configuration limited by any one of the features A1 to A3 or the features B2 to B9 may be applied to the configuration of this feature. In this case, the further effect by having applied each structure can be show | played.

Feature C12. A first signal path (signal line LN1) connecting the update signal output means and the numerical information update means;
A second signal path (signal line LN2) provided separately from the first signal path and connecting the update signal output means and control means for controlling the game;
With
The update signal output means outputs the update clock signal to both the numerical information update means and the control means,
The control means performs control related to a game based on the input of the update clock signal through the second signal path.
The game machine according to Feature C10, wherein the changing means is provided only at an intermediate position of the first signal path among the first signal path and the second signal path.

  According to the feature C12, the fluctuation means is provided in the middle of the first signal path, while the fluctuation means is not provided in the second signal path. As a result, the input timing of the update clock signal input to the numerical information update means can vary, while the update clock signal input to the control means does not vary. Therefore, the effect of the feature C10 can be obtained without affecting the control related to the game.

  The configuration limited by any one of the features A1 to A3 or the features B2 to B9 may be applied to the configuration of this feature. In this case, the further effect by having applied each structure can be show | played.

  Each invention of the above-mentioned feature C group is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Whether or not the big hit state has occurred is determined at the timing when the game ball enters the operation port. For example, it is equipped with a counter that is periodically updated within a certain range (for example, updated every 1 ms in the range of 0 to 300 every 2 ms), and obtains the value of the counter when the game ball enters the operation port Then, when the value of the counter coincides with a predetermined winning value such as “7”, for example, a privilege that the gaming state shifts to the jackpot state is given to the player.

  Here, it is preferable that the counter used in the big hit lottery is updated well. For example, by grasping the update timing of the counter used in the jackpot lottery, the timing at which the value of the counter becomes a value corresponding to the jackpot winning may be grasped. Then, in accordance with the timing, an illegal act that intentionally generates a jackpot by outputting an illegal signal to a regular control board can be considered.

  For example, from the viewpoint of reducing the capacity required for the counter, it is preferable that the range that can be taken by the counter used in the big hit lottery is narrow. However, if the range of the counter used in the jackpot lottery is narrowed, the winning probability derived from the range and the winning value is increased, which may cause a disadvantage that the desired winning probability cannot be set.

  The above problem also applies to other gaming machines that perform lottery using a counter.

Feature D1. In a gaming machine equipped with a control means for controlling a game,
Comprising signal conversion means (signal conversion circuit 402) for converting an AC voltage supplied from an external power source into a clock signal;
The game machine according to claim 1, wherein the control means controls the game based on the input of the clock signal obtained by the signal conversion means.

  According to the feature D1, the clock signal is obtained by converting an AC voltage supplied from an external power source. Thus, for example, a clock signal can be easily obtained by using a commercial power source or a power source of a gaming machine as an external power source. Therefore, the configuration can be simplified.

Feature D2. The control means includes a numerical information updating means (counter circuit 317) for sequentially updating numerical information within a predetermined numerical range, triggered by a predetermined location from the rising edge to the falling edge of the clock signal, and a predetermined acquisition. Numeric information acquired by the acquisition means, the acquisition means (function to execute the processing of step S305 and step S307 in the MPU 311) that acquires the numerical information from the numerical information update means when the condition is satisfied Is in a specific state based on the fact that corresponds to predetermined specific information,
The signal conversion means includes output interval conversion means (frequency conversion circuit 401) for converting the output interval of the signal state corresponding to the trigger so as not to correspond to the cycle of the input AC voltage. The gaming machine according to Feature D1, characterized by:

  According to the feature D2, the specific state is entered when the acquired numerical information corresponds to the specific information. The numerical information is updated with a predetermined location of the clock signal as a trigger.

  Here, the output interval of the signal state corresponding to the trigger in the clock signal is converted so as not to correspond to the cycle of the input AC voltage. Thereby, even if the period of the alternating voltage input is specified, the output interval of the signal state corresponding to the update trigger of numerical information is difficult to specify. Therefore, it is possible to identify the output interval of the signal state corresponding to the trigger for updating the numerical information from the frequency of the input AC voltage, and to suppress the illegal act of specifying the update timing of the numerical information.

  As a more specific configuration of the output interval conversion means, “the frequency of the update clock signal output from the update signal output means is set to be different from the frequency of the input AC voltage. It is possible to adopt a configuration that “is to be converted”.

Feature D3. The numerical information update means is to update the numerical information with a predetermined location from a rising edge to a falling edge in the update clock signal as a trigger,
The signal converting means outputs an update clock signal having a predetermined specific frequency regardless of whether the frequency of the input AC voltage is the first frequency or the second frequency. The gaming machine according to Feature D1 or D2, characterized in that.

  For example, when a commercial power supply is used as the external power supply, the frequency of the AC clock voltage is different between East Japan and West Japan, so the frequency of the update clock signal is also different. Then, since the output interval of the signal state corresponding to the trigger for updating the numerical information is different, the update frequency of the numerical information is different in the area of use, and the fairness of the game is hindered.

  On the other hand, according to this feature, the frequency of the update clock signal is converted to a specific frequency regardless of whether the frequency of the input AC voltage is the first frequency or the second frequency. As a result, the output interval of the signal state corresponding to the trigger for updating the numerical information does not depend on the frequency of the AC voltage, so that the above inconvenience can be avoided.

  Note that the first frequency and the second frequency may be 50 Hz and 60 Hz, which are frequencies of the commercial power supply.

  Each invention of the above-mentioned feature group D is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  The pachinko machine is provided with a control element on which a storage element such as a memory storing a control program related to a game, an arithmetic element that executes the control program, or an MPU in which these control elements are integrated is mounted. What is known. The pachinko machine has a series of games controlled by a control program.

  In the above gaming machine, an oscillation circuit that outputs a clock signal that is a reference for the operation timing of the arithmetic element is provided. The arithmetic element executes the control program by operating a plurality of elements in synchronization with the input of the clock signal output from the oscillation circuit.

  Here, a simple configuration of the oscillation circuit is preferable, and there is still room for improvement in the oscillation circuit.

  Note that the above problem is a common problem in gaming machines that include an oscillation circuit that outputs a clock signal and an arithmetic element that executes a control program related to a game based on the input of the clock signal.

Feature E1. In a gaming machine equipped with a control means (main control board 301) that is in a specific state in the process of controlling the progress of the game and controlling the progress of the game,
A gaming machine comprising: fluctuating means (irregular delay circuit 602 or non-periodic circuit) that fluctuates a period from when a predetermined condition is satisfied until the control means enters the specific state.

  According to the characteristic E1, the period from when the predetermined condition is satisfied to when the control unit is in the specific state varies by the varying unit. As a result, there is a variation in the period from when the predetermined condition is established until the control means enters the specific state. Therefore, the period from when the predetermined condition is satisfied to when the control unit is in the specific state becomes irregular. Therefore, even when the timing of establishment of the predetermined condition is grasped by the “hanging board” or the like, it is difficult to grasp the timing when the control means enters the specific state. Therefore, an illegal act using a “hanging board” or the like can be prevented.

Feature E2. Numerical information updating means for sequentially updating numerical information in a predetermined numerical range every time the update timing comes (function to execute the update process of the big hit random number counter C1 in step S703 in the MPU 311);
Acquisition means for acquiring numerical information updated by the numerical information update means based on the establishment of a predetermined acquisition condition (function for executing the process of storing the big hit random number counter C1 in step S804 in the MPU 311) When,
With
Based on the fact that the numerical information acquired by the acquisition means corresponds to predetermined winning information, a gaming machine is provided with a privilege to the player,
Varying means (irregular delay circuit 602 or non-periodic circuit) for changing a period from when a predetermined condition is satisfied until the numerical information of the numerical information updating means becomes the winning information. Machine.

  According to the characteristic E2, the period from when the predetermined condition is satisfied until the numerical information of the numerical information updating means becomes the winning information is changed by the changing means. As a result, there is a variation in the period from when the predetermined condition is established until when the numerical information becomes the winning information. Therefore, the period from when the predetermined condition is satisfied to when the numerical information becomes the winning information becomes irregular. Therefore, even if the timing of establishment of the predetermined condition is grasped by “hanging board” or the like, it is difficult to grasp the timing at which the numerical information becomes the winning information. Therefore, an illegal act using a “hanging board” or the like can be prevented.

Feature E3. Numerical information updating means for sequentially updating numerical information in a predetermined numerical range every time the update timing comes (function to execute the update process of the big hit random number counter C1 in step S703 in the MPU 311);
Acquisition means for acquiring numerical information updated by the numerical information update means based on the establishment of a predetermined acquisition condition (function for executing the process of storing the big hit random number counter C1 in step S804 in the MPU 311) When,
With
Based on the fact that the numerical information acquired by the acquisition means corresponds to predetermined winning information, a gaming machine is provided with a privilege to the player,
Fluctuation that varies the period from the execution timing of the predetermined operation that allows the numerical information to be sequentially updated from the predetermined numerical value until the numerical information becomes the winning information according to the execution timing of the predetermined operation A gaming machine comprising means (irregular delay circuit 602 or non-periodic circuit).

  According to the feature E3, the period from the execution timing of the predetermined operation that enables the numerical information to be sequentially updated from the predetermined numerical value to the time when the numerical information becomes the winning information varies according to the execution timing of the predetermined operation. ing. As a result, a variation occurs in a period from the execution timing of the predetermined operation to the timing when the numerical information becomes the winning information. Therefore, the period from the execution timing of the predetermined operation to the timing when the numerical information becomes the winning information becomes irregular. Accordingly, since it is difficult to grasp the period from the execution timing of the predetermined operation to the timing when the numerical information becomes the winning information, even if the execution timing of the predetermined operation is grasped, the timing when the numerical information becomes the winning information is difficult to grasp. Therefore, fraudulent acts such as “hanging board” can be suppressed.

Feature E4. The numerical information updating means that operates in a state in which operating power is supplied to the control means that performs control related to the game, and that sequentially updates the numerical information within a predetermined numerical range at each update timing (a big hit in step S703 in the MPU 311) A function of executing update processing of the random number counter C1),
Acquisition means for acquiring numerical information updated by the numerical information update means based on the establishment of a predetermined acquisition condition (function for executing the process of storing the big hit random number counter C1 in step S804 in the MPU 311) When,
With
Based on the fact that the numerical information acquired by the acquisition means corresponds to predetermined winning information, a gaming machine is provided with a privilege to the player,
Fluctuation means for varying a period from a supply start timing at which operating power is supplied to the control means to an update start timing at which the numeric information update unit starts updating the numeric information according to the supply start timing. A gaming machine comprising an irregular delay circuit 602 or a non-periodic circuit).

  According to feature E4, since the period from the supply start timing at which operating power is supplied to the control means to the update start timing at which the update of numerical information is started varies according to the supply start timing, the update starts from the supply start timing. Variations occur in the period up to the timing. As a result, the period from the supply start timing to the update start timing becomes irregular. Therefore, even if the numerical information updating means starts updating from a predetermined initial value, the period from the supply start timing until the numerical information matches the winning information becomes irregular, so the period is Difficult to grasp. Therefore, the “hanging board” or the like can suppress an illegal act of illegally obtaining a privilege by outputting a signal at the timing when the numerical information coincides with the winning information.

Feature E5. In feature E4, supply means (reset circuit 601, power supply and launch control board 321) that enters a supply state in which a signal or power is supplied based on the start of supply of operating power to the control means,
A supply path (signal line LN4) connecting the supply means and the numerical information update means;
With
The numerical information update means starts updating when the supply means is in the supply state and the state of a signal or power supplied from the supply path becomes a predetermined operable state,
The changing means is provided at a midway position in the supply path, and changes a period from the timing when the supply state is reached to the timing when the operation is enabled according to the timing when the supply state is set. A gaming machine.

  According to the characteristic E5, the numerical information update unit and the supply unit are connected via the supply path. The supply means enters a supply state in which a signal or power is supplied based on the start of supply of operating power to the control means. In addition, when the supply unit is in a supply state and the state of a signal or power supplied from the supply path becomes a predetermined operable state, the numerical information update unit starts updating. Here, a fluctuating means is provided at an intermediate position in the supply path, and the period from the timing when the supply state is reached to the timing when the operation becomes possible varies depending on the timing when the supply state is reached. As a result, the period from the supply state timing to the operable state becomes irregular, and therefore the period from the supply start timing to the update start timing becomes irregular. Therefore, since the period from the supply start timing until the numerical information matches the winning information becomes irregular, it is difficult to grasp the period. Accordingly, fraudulent acts using a “hanging board” or the like can be prevented.

  Further, since the period from the timing when the supply state is reached to the timing when the operation becomes possible is irregular, there is no need to change the update start timing in the numerical information updating means. Therefore, the configuration of the numerical information updating unit can be simplified.

  Feature E6. In the feature E5, the fluctuation unit can store and discharge the supplied charge, and charge / discharge unit (capacitor 613) stores the charge when the supply unit is in the supply state. When the charge accumulated in the charging / discharging unit is accumulated more than a predetermined amount, the state of the signal or power supplied from the supply path to the numerical information updating unit is shifted to the operable state. A gaming machine characterized by being made to be.

  According to the characteristic E6, when the supply unit is in the supply state, the charge is accumulated in the charge / discharge unit, and when the charge is accumulated in the charge / discharge unit in a predetermined amount or more, the state shifts to the operable state. As a result, the timing at which the supply means becomes operable is delayed with respect to the timing at which the supply means is in the supply state only during a period in which a predetermined amount or more of charge is accumulated in the charge / discharge means. On the other hand, when the supply means is not in a supply state, that is, when operating power is not supplied to the control means, the charge accumulated in the charge / discharge means is gradually released. That is, the charging / discharging means is in a discharging state. When the supply unit is again in the supply state under the discharge state, the charge / discharge unit is switched from the discharge state to the charge state. Then, the timing at which the operation becomes possible is delayed only during a period until a predetermined amount of charge is accumulated again in the charge / discharge means. The delay period varies according to the residual charge amount in the charge / discharge unit at the time when the supply unit is in the supply state. Further, the residual charge amount varies depending on the timing at which the supply unit enters the supply state under the discharge state of the charge / discharge unit. As a result, the period from the timing when the supply means enters the supply state to the timing when the supply means enters the operable state varies based on the timing when the supply means enters the supply state. Therefore, it is possible to suppress an illegal act using a “hanging board” or the like with a simple configuration in which charging / discharging means is provided.

  Feature E7. In the characteristic E6, the variation means includes an integration circuit (integration circuit 611) having at least one capacitor (capacitor 613) and at least one resistance (resistance 614) as the charge / discharge means. A gaming machine.

  According to the characteristic E7, a charge period from the start of charge accumulation until the charge is accumulated up to the predetermined amount, and a discharge from the start of discharge of the accumulated charge until the accumulated charge is lost Since the period is set based on the capacitance of the capacitor of the integrating circuit and the resistance value of the resistor, the charging period and the discharging period can be adjusted by adjusting both. Thereby, by extending the charging period and the discharging period, it is possible to increase the variation of the delay period and the variation of the residual charge amount that varies depending on the discharging period. Therefore, the update start timing of the numerical value updating means can be made irregular, making it difficult to grasp the timing.

  Feature E8. In the feature E6 or the feature E7, the fluctuating unit is configured to perform a discharge period from the start of the discharge of the accumulated charge to the loss of the accumulated charge in the charge / discharge unit after the charge accumulation is started. A gaming machine comprising a period changing means (switching circuit 621) for making the charging period longer than the charging period until the predetermined amount of charge is accumulated.

  From the viewpoint of variation in the delay period, the charge period from the start of charge accumulation until the charge is accumulated up to the predetermined amount, and from the start of discharge of the accumulated charge until the accumulated charge is lost The discharge period is preferably longer. In particular, it is preferable that the discharge period contributing to the variation in the residual charge amount is long. However, in the case of an integration circuit, for example, the charging period and the discharging period are almost the same. Therefore, if the charging period becomes longer by extending the discharging period, the update start timing of the numerical information updating means is excessively delayed. Inconvenience may occur. On the other hand, according to the feature E8, the discharging period is longer than the charging period by the period changing means. As a result, the above-described problem can be avoided while ensuring the variation in the delay period.

Feature E9. In feature E5, the changing means is a transition means (synthesizer circuit 641, D flip-flop 651, etc.) that receives the specific signal from specific signal output means (signal conversion circuit 402) that outputs a specific signal in a specific form at a specific timing. With
The shift means is configured to change the numerical value from the supply path based on the fact that the supply means is in the supply state, and the specific signal output from the specific signal output means is in the specific form. A gaming machine characterized in that the state of a signal or power supplied to the information updating means is shifted to the operable state.

  According to the feature E9, a specific signal that is in a specific form at a specific timing is output to the transition unit by the specific signal output unit. Then, based on the fact that the supply means is in the supply state and the specific signal output from the specific signal output means is in a specific form, the signal or power supplied from the supply path to the numerical information update means The state of becomes a ready state. As a result, when the supply means is in the supply state under the condition where the specific signal output from the specific signal output means is in a form other than the specific form, the specific signal output from the specific signal output means is in the specific form. The transition to the ready state is delayed until. In addition, the delay period varies depending on the form of the specific signal with respect to the timing at which the supply unit enters the supply state. As a result, the period from the timing when the supply means enters the supply state to the timing when the supply means enters the operable state varies based on the timing when the supply means enters the supply state. Therefore, since the update start timing of the numerical information update means is irregular, it is difficult to grasp the timing. Therefore, fraudulent acts using a “hanging board” or the like can be suppressed.

  Further, in the configuration in which the charging / discharging means is provided as the changing means, when the period during which the operating power is not supplied to the control means is longer than the discharging period, there is no problem that the delay period does not vary because no charge remains in the charging / discharging means. Arise. On the other hand, according to the feature E9, the delay period does not depend on the period in which the operating power is not supplied to the control unit, and thus the above inconvenience can be avoided.

Feature E10. In feature E5, the changing unit outputs a specific signal that is in a specific form at a specific timing (signal conversion circuit 402);
Based on the fact that the supply means is in the supply state and the specific signal output from the specific signal output means is in the specific form, supply from the supply path to the numerical information update means Transition means (synthesizer circuit 641, D flip-flop 651, etc.) for shifting the state of the signal or power to be operated to the operable state;
A gaming machine characterized by comprising:

  According to the feature E10, a specific signal that is in a specific form at a specific timing is supplied to the transition unit by the specific signal output unit. Then, based on the fact that the supply means is in the supply state and the specific signal output from the specific signal output means is in a specific form, the signal or power supplied from the supply path to the numerical information update means The state of becomes a ready state. As a result, when the supply means is in the supply state under the condition where the specific signal output from the specific signal output means is in a form other than the specific form, the specific signal output from the specific signal output means is in the specific form. The transition to the ready state is delayed until. In addition, the delay period varies depending on the form of the specific signal with respect to the timing at which the supply unit enters the supply state. As a result, the period from the timing when the supply means enters the supply state to the timing when the supply means enters the operable state varies based on the timing when the supply means enters the supply state. Therefore, since the update start timing of the numerical information update means is irregular, it is difficult to grasp the timing. Therefore, fraudulent acts using a “hanging board” or the like can be suppressed.

  Further, in the configuration in which the charging / discharging means is provided as the changing means, when the period during which the operating power is not supplied to the control means is longer than the discharging period, there is no problem that the delay period does not vary because no charge remains in the charging / discharging means. Arise. On the other hand, according to the feature E10, the delay period does not depend on the period during which the operating power is not supplied to the control unit, and thus the above inconvenience can be avoided.

Feature E11. In the feature E10, the specific signal output from the specific signal output means is a signal in which an HI level signal and a LOW level signal are alternately output,
The transition means is based on the fact that the supply means is in the supply state, and that either one of the HI level signal and the LOW level signal is output from the specific signal output means. A gaming machine characterized in that it is a device (synthesizing circuit 641) to be shifted to a possible state.

  According to feature E11, the operation is possible based on the supply means being in the supply state and one of the HI level signal and the LOW level signal being output from the specific signal output means to the transition means. It becomes a state. For example, if the supply means is in the supply state and the transition means shifts to the operable state based on the fact that the HI level signal is output from the specific signal output means, the LOW level signal is When the supply unit is in the supply state under the state of being output from the specific signal output unit, the transition to the operable state is delayed until the HI level signal is output from the specific signal output unit. The delay period varies depending on the form of the specific signal with respect to the timing of the supply state. Thereby, since the update start timing of the numerical information updating means is irregular, it is difficult to grasp the timing. Therefore, an illegal act using a “hanging board” or the like can be prevented.

Feature E12. In the feature E11, the specific signal output means outputs a signal in which a period of the HI level signal and a period of the LOW level signal are relatively different from each other.
The transition means is based on the fact that the supply means is in the supply state, and a signal of a relatively short period is output from the specific signal output means among the HI level signal and the LOW level signal. A gaming machine that is shifted to the operable state.

  For example, if the supply means is in the supply state and the transition means shifts to the operable state based on the fact that the HI level signal is output from the specific signal output means, the LOW level signal is the specific signal. When the supply unit is in the supply state under the state of being output from the output unit, the transition to the operable state is delayed until the HI level signal is output from the specific signal output unit. However, when the supply unit enters the supply state in a state where the HI level signal is output from the specific signal output unit, the state immediately shifts to the operable state, which causes a problem that no delay occurs. That is, there is a period in which there is no delay with respect to the timing at which the supply unit enters the supply state. On the other hand, according to the feature E12, the specific signal output means outputs a signal in which the period of the HI level signal and the period of the LOW level signal are different. Then, the supply unit enters the supply state, and further shifts to the operable state based on the fact that a signal having a relatively short period is output from the specific signal output unit among the HI level signal and the LOW level signal. Thereby, since the period when a delay does not occur becomes shorter than the period when a delay occurs, the above-described problem can be suppressed.

Feature E13. In the feature E10, the specific signal output from the specific signal output means is a signal in which an HI level signal and a LOW level signal are alternately output,
In the transition means, the supply means is in the supply state, and the output state of the specific signal output from the specific signal output means is changed between the HI level signal and the LOW level signal. Based on this, the gaming machine is a device (D flip-flop 651) that shifts to the operable state.

  According to feature E13, the supply means is in a supply state, and is operable based on the fact that the output state of the specific signal output from the specific signal output means has changed between the HI level signal and the LOW level signal. Transition to the state. As a result, the transition to the operable state is delayed until the output state of the specific signal output from the specific signal output unit after the supply unit enters the supply state changes between the HI level signal and the LOW level signal. The The delay period varies depending on the form of the specific signal with respect to the timing at which the supply unit enters the supply state. Thereby, since the update start timing of the numerical information updating means is irregular, it is difficult to grasp the timing. Therefore, an illegal act using a “hanging board” or the like can be prevented.

  Further, since the output state of the specific signal shifts to the operable state based on the change between the HI level signal and the LOW level signal, the timing at which the supply unit enters the supply state and the output state of the specific signal are HI. A delay occurs as long as the timing changing between the level signal and the LOW level signal does not match. In other words, the period in which no delay occurs is shorter compared to the configuration in which one of the HI level signal and the LOW level signal shifts based on being output from the specific signal output means. Therefore, it is possible to suppress the problem that no delay occurs.

  Feature E14. In any one of the characteristics E10 to E13, the specific signal output means converts the HI level signal and the HI level signal by converting an alternating voltage supplied from an external power source into a pulse signal based on a predetermined threshold voltage. A gaming machine that generates a specific signal in which the LOW level signal is alternately output.

  According to the feature E14, the specific signal from which the HI level signal and the LOW level signal are alternately output is obtained by converting the AC voltage supplied from the external power source into a pulse signal. Thereby, for example, a desired pulse signal can be easily obtained by using a commercial power source or a power source of a gaming machine as an external power source. Therefore, the configuration can be simplified.

  The conversion from the AC voltage to the pulse signal is performed with reference to a predetermined threshold voltage. Thereby, a pulse signal having a desired pulse width can be easily obtained by changing the threshold voltage. Therefore, the configuration of the feature E12 can be easily realized.

Feature E15. In any one of features E10 to E14, the specific signal output means includes pulse signal output means (signal conversion circuit 402) for outputting a pulse signal at a predetermined cycle,
The specific signal is generated using the pulse signal, and is based on the pulse signal being in a predetermined form, and is in the specific form.
After the timing when the supply means is in the supply state, the specific signal becomes the specific form based on a predetermined form after the first predetermined form in the pulse signal output from the pulse signal output means. A gaming machine comprising delay means (modulation circuit 662) for generating a signal.

  According to the feature E15, the specific signal is generated using the pulse signal output from the pulse signal output means. Further, the specific signal is in a specific form based on the pulse signal having a predetermined form. Then, after the timing when the supply means is in the supply state, the specific signal does not become the specific form based on the first predetermined form in the pulse signal. Thus, when the supply unit is in the supply state, the transition to the operable state based on the first predetermined form in the pulse signal after the timing at which the supply unit is in the supply state is not executed. Therefore, it is difficult to grasp the update start timing of the numerical information updating means. Therefore, it is possible to prevent an improper act of grasping the timing when the supply means enters the supply state and the timing when the pulse signal is in a predetermined form, and grasping the update start timing of the numerical information update means.

Feature E16. In any one of features E13 to E15, the specific signal output unit includes a pulse signal output unit (signal conversion circuit 402) that outputs a pulse signal at a predetermined period;
By changing at least one of the repetition interval or the pulse width of the pulse signal output from the pulse signal output means, at least one of the repetition interval or the pulse width is an HI level corresponding to the change as the specific signal. Signal changing means (modulation circuit 662, modulation circuit 671) for generating a signal to be output;
With
The transition means is moved to the operable state based on the fact that the supply means is in the supply state and the output state of the specific signal has changed between the HI level signal and the LOW level signal. A gaming machine characterized by being transferred.

  According to the feature E16, the pulse signal output from the pulse signal output unit and the signal from which the HI level signal as the specific signal is output differ in at least one of the repetition interval and the pulse width. Then, based on the fact that the output state of the specific signal has changed between the HI level signal and the LOW level signal, the state of the signal or power supplied from the supply path to the numerical information updating means shifts to the operable state. To do. As a result, the timing at which the operation becomes possible is different from the case of shifting based on the change in the output state of the pulse signal output from the pulse signal output means. Therefore, it is possible to prevent an illegal act of grasping the timing at which the operation is enabled from the output state of the pulse signal output from the pulse signal output unit and the timing at which the supply unit is in the supply state.

  Feature E17. In feature E16, the signal changing unit changes at least one of the repetition interval or the pulse width of the pulse signal output from the pulse signal output unit, so that at least one of the repetition interval or the pulse width is used as the specific signal. However, the game machine is characterized in that it generates a signal (signal conversion circuit 402) that outputs a HI level signal larger than the pulse signal output from the pulse signal output means.

  According to the characteristic E17, the signal changing unit changes at least one of the repetition interval or the pulse width of the HI level signal as the specific signal to be larger than that of the pulse signal output from the pulse signal output unit. Therefore, the range of the delay period, which is the difference between the timing when the supply means enters the supply state and the timing when the output state of the specific signal changes, becomes large. This increases the variation in the delay period. Therefore, since the update start timing of the numerical information update means becomes more irregular, it is difficult to grasp the timing. It is possible to prevent fraud using a “hanging board” or the like more preferably.

  Feature E18. In the feature E16 or the feature E17, the signal changing unit changes at least one of a repetition interval or a pulse width of the pulse signal output from the pulse signal output unit, so that the HI level signal is at least as the specific signal. A gaming machine which generates at least one of a signal output at two kinds of repetition intervals or a signal at which a pulse signal of at least two kinds of pulse widths is outputted (modulation circuit 671).

  According to the feature E18, as the specific signal, the HI level signal is output at at least two repetition intervals, or the HI level signal having at least two pulse widths is output. As a result, the output state of the specific signal changes at least at two intervals. Therefore, it is difficult to grasp the timing at which the output state of the specific signal changes. Therefore, it is difficult to grasp the timing when the operation becomes possible. Accordingly, fraudulent acts using a “hanging board” or the like can be prevented.

Feature E19. In the feature E17 or the feature E18, the signal change unit generates a change signal using the pulse signal from a standby state based on the start of supply of operating power to the control unit. A change signal generating means (second D flip-flop 663, third D flip-flop 664, etc.) for shifting to the generation state;
The signal changing means outputs an HI level signal in which at least one of a repetition interval or a pulse width is changed using the changing signal when the changing signal generating means enters the changing signal generating state. Signal generation,
A power supply unit for power interruption (power supply unit for power interruption 321c) for supplying operating power to the signal generator for change in a situation where the supply of operating power to the control unit is stopped;
The change signal generation means is a stop that is in the change signal generation state when the supply of the operation power to the control means is stopped while the operation power is supplied from the power interruption power supply means A gaming machine which stores a state and further shifts from the stop state to the change signal generation state based on the start of supply of operating power to the control means.

  According to the feature E19, the change signal generation unit shifts from the standby state to the change signal generation state in which the change signal is generated based on the start of the supply of the operating power to the control unit. In the change signal generation state, a signal that outputs an HI level signal in which at least one of the repetition interval or the pulse width is changed is generated from the signal change means using the change signal.

  Here, while the operating power is supplied from the power interruption power supply means, the stop state, which is the change signal generation state when the supply of the operating power to the control means is stopped, is stored. Then, based on the start of the supply of operating power to the control means, the state shifts from the stop state to the change signal generation state. As a result, the standby state of the change signal generating means at the start timing of supply of operating power to the control means varies. Therefore, the variation in the output timing of the specific signal is larger than in the configuration in which the standby state at the operation power supply start timing is the same. Accordingly, since the range of delay period variation is large, the delay period variation is large. Therefore, the update start timing of the numerical information update means can be made more irregular.

Feature E20. In feature E19, the storage unit stores information used when the control unit performs control, and stores storage information (RAM 316) that stores the information while power is supplied to itself.
The power interruption power supply means supplies power to the storage means and power to the change signal generation means in a situation where the supply of operating power to the control means is stopped. A gaming machine characterized by being a thing.

  According to the feature E20, the information stored in the storage unit is held by the power supply unit for power interruption, and the stop state of the change signal generation unit is stored. Thereby, simplification of a structure can be achieved.

Feature E21. In any one of features E5 to E20, as the supply path, a first supply path (signal line LN3) that does not pass through the changing means, and a second supply path (signal line LN4) that passes through the changing means, As well as
When both of the signals or power supplied from both supply paths to the numerical information update means are in the operable state, an update start signal for starting update of the numerical information update means is sent to the numerical information While outputting to the update means, if at least one signal or power state of both supply paths is not the operable state, a stop signal for stopping the update of the numerical information update means is sent to the numerical information update means. A gaming machine comprising update instruction means (NAND circuit 612) for outputting.

  According to the feature E21, the supply unit and the numerical information update unit are connected by the first supply path that does not pass through the changing unit and the second supply path that passes through the changing unit. When both the signals supplied to the numerical information updating means from both supply paths and the power state are operable, an update start signal for starting updating of the numerical information updating means is sent to the numerical information updating means. Is output. In response to the input of the signal, the numerical information updating means starts updating. Thereby, even if the state of the signal or power supplied from the first supply path to the numerical information updating means is an operable state, the state from the second supply path via the varying means is not an operable state. In this case, the update start signal is not output to the numerical information update unit. Therefore, the effect of delay by the varying means is ensured.

  On the other hand, if the state of the signal or power supplied from at least one of the two supply paths to the update instruction means is not operable, a stop signal is output to the numerical information update means by the update instruction means. . In response to the input of the stop signal, the update of the numerical information update unit is stopped. Thereby, the update of the numerical information updating unit can be stopped without waiting for the state of the signal or power supplied from the second supply path to the numerical information updating unit to shift to the operable state. Accordingly, it is possible to suppress the inconvenience of the malfunction of the numerical information updating unit due to the delay of the input of the stop signal to the numerical information updating unit.

Feature E22. In any one of the characteristics E5 to E21, the supply unit is an operation signal output unit (reset circuit 601) that outputs an operation signal (reset signal) when the supply state is reached.
Based on the fact that the operation signal is output from the operation signal output unit, the changing unit outputs a relay result signal that is the same as or corresponding to the operation signal to the numerical information update unit through the supply path. And the period from the output start timing of the operation signal from the operation signal output means to the output start timing of the relay result signal varies according to the output start timing of the operation signal. It is what
The numerical information updating means operates when operating power is supplied through a path different from the supply path, and when the relay result signal is input through the supply path. A gaming machine.

  According to the feature E22, based on the fact that the operation signal is output from the operation signal output means, the relay result signal that is the same as or corresponding to the operation signal is output to the numerical information update means through the supply path. Has been. Then, when the relay result signal is input through the supply route and the operating power is supplied through a route different from the supply route, the update by the numerical information update unit is started. Here, the period from the output start timing of the operation signal from the operation signal output means to the output start timing of the relay result signal varies depending on the output start timing of the operation signal. Thereby, since the start timing of the update by the numerical information updating means is irregular, it is difficult to grasp the update start timing of the numerical information updating means. Therefore, an illegal act using a “hanging board” or the like can be prevented.

Feature E23. In features E10 to E22, a board box (board box 163) that houses the numerical information updating means;
Fixing means (sealing portion 164) for fixing the substrate box in a state where it cannot be opened or difficult to open;
With
At least the transition means is accommodated in the board box.

  According to feature E23, at least the transition means and the numerical information update means are accommodated in the substrate box. The substrate box is fixed in a state where it cannot be opened or difficult to open by a fixing means. Thereby, it is possible to prevent an illegal act against the numerical information updating means and an illegal act against the transition means. Therefore, it is possible to suitably suppress an illegal act against the transition unit while simplifying the configuration.

Feature E24. In any one of features E1 to E23, a substrate box (substrate box 163) that houses the numerical information updating means;
Fixing means (sealing portion 164) for fixing the substrate box in a state where it cannot be opened or difficult to open;
With
The game machine characterized in that the changing means is accommodated in the board box.

  According to the feature E24, the changing means and the numerical information updating means are accommodated in the board box. The substrate box is fixed in a state where it cannot be opened or difficult to open by a fixing means. Thereby, it is possible to prevent an illegal act against the numerical information updating means and an illegal act against the changing means. Therefore, it is possible to suitably suppress fraud against the changing means while simplifying the configuration.

Feature E25. Numerical information updating means for sequentially updating numerical information in a predetermined numerical range every time the update timing comes (function to execute the update process of the big hit random number counter C1 in step S703 in the MPU 311);
Acquisition means for acquiring numerical information updated by the numerical information update means based on the establishment of a predetermined acquisition condition (function for executing the process of storing the big hit random number counter C1 in step S804 in the MPU 311) When,
Start signal output means (RAM erase signal output circuit 802) for outputting a start signal (RAM erase signal) when a predetermined operation condition is satisfied;
With
Based on the fact that the numerical information acquired by the acquisition means corresponds to predetermined winning information, a privilege is given to the player,
In the gaming machine in which the numerical information update means starts updating the numerical information from a predetermined initial value based on the output of the activation signal from the activation signal output means,
The period from the establishment timing of the predetermined operating condition to the update start timing at which the numerical information updating means starts updating the numerical information from the predetermined initial value is varied according to the establishment timing of the predetermined operating condition. A gaming machine comprising a varying means (irregular delay circuit 602 or non-periodic circuit).

  According to the feature E25, when a predetermined operation condition is satisfied (for example, a switch provided in the gaming machine is operated), an activation signal is output from the activation signal output unit, and a predetermined signal is output according to the output of the signal. The numerical information is updated from the initial value. Here, since the period from the establishment timing of the predetermined operating condition to the update start timing at which the update of the numerical information is started from the predetermined initial value varies depending on the establishment timing, the period from the establishment timing to the update start timing is Variation occurs. As a result, the period from the establishment timing to the update start timing becomes irregular. Therefore, even if the numerical information updating means starts updating from a predetermined initial value, the period from when the predetermined operating condition is met until the numerical information matches the winning information becomes irregular. The period is difficult to grasp. Therefore, the “hanging board” or the like can suppress an illegal act of illegally obtaining a privilege by outputting a signal in accordance with the timing when the numerical information coincides with the winning information.

  In addition, it is possible to apply the technical idea shown in the features E5 to E18 and the features E21 to E24 to this feature. In this case, “based on the start of supply of operating power to the control means” is replaced with “based on the establishment of the predetermined operating condition”.

  The “predetermined initial value” includes not only a predetermined initial value but also an initial value acquired from a means for generating predetermined initial value information.

Feature E26. Numerical information updating means for sequentially updating numerical information in a predetermined numerical range every time the update timing comes (function to execute the update process of the big hit random number counter C1 in step S703 in the MPU 311);

With
Based on the fact that the numerical information acquired by the acquisition means corresponds to predetermined winning information, a privilege is given to the player,
In the gaming machine that starts updating the numerical information from a predetermined initial value based on the initial value setting operation being received by the receiving means,
Fluctuation means (irregular delay circuit 602) that varies the period from the acceptance of the initial value setting operation to the update start timing from the predetermined initial value according to the acceptance timing of the initial value setting operation. Or a non-periodic circuit).

  According to the feature E26, the update of the numerical information is started from the predetermined initial value based on the reception of the initial value setting operation by the receiving unit. Here, since the period from the reception timing of the initial value setting operation to the update start timing at which the update of the numerical information is started varies depending on the reception timing, the period from the reception timing to the update start timing varies. As a result, the period from the reception timing to the update start timing becomes irregular. Therefore, even if the numerical information updating means starts updating from a predetermined initial value, the period until the numerical information matches the winning information from the reception timing of the initial value setting operation becomes irregular, The period is difficult to grasp. Therefore, the “hanging board” or the like can suppress an illegal act of illegally obtaining a privilege by outputting a signal in accordance with the timing when the numerical information coincides with the winning information.

  In addition, it is possible to apply the technical idea shown in the features E5 to E18 and the features E21 to E24 to this feature. In this case, “based on the start of supply of operating power to the control means” is replaced with “based on accepting the initial value setting operation”.

  The “predetermined initial value” includes not only a predetermined initial value but also an initial value acquired from a means for generating predetermined initial value information.

  Each invention of the above-mentioned feature group E is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Whether or not the big hit state has occurred is determined at the timing when the game ball enters the operation port. For example, it is equipped with a counter that is periodically updated within a certain range (for example, updated every 1 ms in the range of 0 to 300 every 2 ms), and obtains the value of the counter when the game ball enters the operation port Then, when the value of the counter coincides with a predetermined value such as “7”, for example, a privilege that the gaming state shifts to the jackpot state is given to the player.

  Here, an illegal act using an illegal substrate called “hanging substrate” may be performed. The fraudulent act is to illegally generate a jackpot state by hanging an unauthorized substrate with respect to a regular control substrate. Specifically, a counter that is synchronized with the counter used in the jackpot lottery is provided on the “hanging board”, and the value of the counter is reset to “0” when the pachinko machine is turned on, etc. Understand the timing of the occurrence of jackpot status. Then, in accordance with the occurrence timing of the jackpot state, an illegal entry detection signal is output from the “hanging board” to the regular control board, and the jackpot state is illegally generated.

  On the other hand, a gaming machine that changes the initial value of the counter update every time the counter used in the jackpot lottery is updated is conceivable. According to the gaming machine, since the initial value of the counter update is changed every time the counter is rotated, it is difficult to grasp the occurrence timing of the jackpot by the “hanging board”. Further, separately from the periodic update process, the initial value to be changed cannot be grasped by performing the update process of the initial value random number counter in the remaining time of a predetermined loop process for performing game control.

  However, even with such a configuration, when the control board is initialized when recovering from a power failure or when the RAM is cleared, information such as the values of various counters stored in the storage means such as the RAM is cleared. Therefore, immediately after initialization, the value of the random number counter used in the jackpot lottery or the initial value random number counter used when determining the initial value of the random number counter is set to a predetermined value such as “0”, for example. Is done. As a result, immediately after the initialization of the control board, the occurrence timing of the jackpot may be easily grasped by the “hanging board”. Therefore, it is conceivable to carry out an initialization process and perform an illegal act that generates a jackpot.

  It should be noted that various misconducts are assumed in gaming machines, and the act of performing fraud based on the result of grasping the predetermined processing timing in the control subject as described above is the “hanging board” as described above. Other than the act by. Such fraudulent acts are not limited to pachinko machines, but are also the same in slot machines.

Feature F1. Numerical information update means (update function of the big hit random number counter C1 of the counter update circuit 701) for sequentially updating numerical information in a predetermined numerical range at each update timing;
Based on the establishment of a predetermined acquisition condition, numerical information acquisition means for acquiring numerical information updated by the numerical information update means (a process of storing the big hit random number counter C1 in step S804 in the MPU 311 is executed). Function)
With
Based on the fact that the numerical information acquired by the numerical information acquisition means corresponds to predetermined winning information, in a gaming machine in which a privilege is granted to the player,
In a situation where operating power is supplied to the control means for controlling the game, the initial value information is sequentially updated in the numerical range every time the update timing is reached, and no operating power is supplied to the control means. Initial value information update means configured to prevent initialization of the initial value information (update function of the initial value random number counter CF of the counter update circuit 701);
An initial value information acquisition unit (a function of executing an initial value setting process in the MPU 311) for acquiring the initial value information from the initial value information update unit based on the supply of operating power to the control unit;
With
When the initial value information is acquired, the numerical information update means updates the numerical information from the acquired initial value information.

  According to the characteristic F1, the initial value information is acquired by the initial value information acquisition unit based on the supply of operating power to the control unit, and the numerical information is updated from the initial value information. Since the initial value information is sequentially updated in a situation where operating power is supplied to the control means, the initial value information varies depending on the timing at which operating power is no longer supplied to the control means. The initial value information is not initialized even in a situation where operating power is not supplied to the control means. As a result, the initial value information acquired by the initial value information acquiring means varies. Therefore, since it is difficult to grasp the initial value information, it is difficult to grasp the timing at which the numerical information becomes the winning information. Therefore, fraudulent acts caused by “hanging board” or the like can be suppressed.

Feature F2. Numerical information update means (update function of the big hit random number counter C1 of the counter update circuit 701) for sequentially updating numerical information in a predetermined numerical range at each update timing;
Based on the establishment of a predetermined acquisition condition, numerical information acquisition means for acquiring numerical information updated by the numerical information update means (a process of storing the big hit random number counter C1 in step S804 in the MPU 311 is executed). Function)
With
Based on the fact that the numerical information acquired by the numerical information acquisition means corresponds to predetermined winning information, in a gaming machine in which a privilege is granted to the player,
In a situation where operating power is supplied to the control means for controlling the game, the initial value information is sequentially updated in the numerical range every time the update timing is reached, and no operating power is supplied to the control means. Initial value information updating means for sequentially updating the initial value information (updating function of the initial value random number counter CF of the counter updating circuit 701),
An initial value information acquisition unit (a function of executing an initial value setting process in the MPU 311) for acquiring the initial value information from the initial value information update unit based on the supply of operating power to the control unit;
With
When the initial value information is acquired, the numerical information update means updates the numerical information from the acquired initial value information.

  According to the feature F2, the initial value information is acquired by the initial value information acquisition unit based on the supply of operating power to the control unit, and the numerical information is updated from the initial value information. Since the initial value information is updated even when operating power is not supplied to the control unit, the initial value information acquired by the initial value information acquiring unit is stored in the operating unit. It fluctuates according to the timing at which is supplied. Thereby, since it is difficult to grasp the initial value information, it is difficult to grasp the timing at which the numerical information becomes the winning information. Therefore, fraudulent acts caused by “hanging board” or the like can be suppressed.

  In particular, when initial value information is held in a situation where operating power is not supplied to the control means, the stored initial value information may be grasped by a “hanging board” or the like. On the other hand, according to this feature, since the initial value information is constantly updated, it is difficult to grasp the initial value information compared to a configuration that holds the initial value information. As a result, it is possible to more appropriately suppress an illegal act caused by a “hanging board” or the like.

Feature F3. Storage means (RAM 316) for storing information used when the control means performs control related to the game;
Initialization execution means (function to execute the processing of step S408 and step S409 in the main processing of the MPU 311) for initializing information stored in the storage means when a predetermined initialization operation is received;
With
The gaming machine according to Feature F1 or Feature F2, wherein the initialization execution unit is configured to exclude the initial value information from an initialization target.

  According to the feature F3, the initial value information is excluded from the initialization target. If the initial value information is to be initialized, the initial value information becomes a predetermined numerical value by performing the initialization. Then, since the numerical value is acquired by the initial value information acquiring unit, the initial value information of the numerical information updating unit when the initialization is performed does not change. On the other hand, in this feature, the initial value information is not affected by the initialization because the initial value information is excluded from the initialization target. Thereby, since the initial value information when the initialization is performed varies, the variation of the initial value information of the numerical information updating means when the initialization is performed is ensured. Therefore, it is possible to suppress an illegal act of grasping the initial value information by intentionally executing the initialization.

  Feature F4. In any one of the characteristics F1 to F3, the initial value information acquisition unit is configured to update the numerical information of the numerical information update unit once in a situation where operating power is supplied to the control unit. A gaming machine that acquires the initial value information.

  According to the feature F4, in a situation where operating power is supplied to the control unit, the initial value information of the initial value information update unit is acquired each time the numerical information of the numerical information update unit makes one round. The numerical information is updated from the initial value information. Thus, the initial value information updating unit and the initial value information obtaining unit are also used as an initial value determining unit that determines the initial value of the numerical information every time the numerical information of the numerical information updating unit makes one round. Therefore, it is possible to reduce the processing load and simplify the configuration while making it difficult to grasp the timing at which the numerical information becomes the winning information.

  Feature F5. In any one of the characteristics F1 to F4, a changing unit that varies a period from a supply start timing at which operating power is supplied to the control unit to an acquisition timing to acquire the initial value information according to the supply start timing A gaming machine comprising an (irregular delay circuit 602 or non-periodic circuit).

  According to the feature F5, the period from the supply start timing to the initial value information acquisition timing is changed by the changing means. Thereby, since the acquired initial value information varies, the initial value information when the update of the numerical information updating unit is started varies. Therefore, it is difficult to grasp initial value information when the numerical information updating unit starts updating. Therefore, even if the supply start timing and the initial value information of the initial value information updating means are grasped by the “hanging board” or the like, it is difficult to grasp the timing when the numerical information becomes the winning information. Therefore, fraudulent acts using the “hanging board” or the like can be suppressed.

  The technical idea shown in the features E5 to E20 and the features E22 to E24 can be applied to this feature. In this case, “numerical information update means” is “initial value information acquisition means”, “start update” is “initial value information acquisition”, “update start timing” is “initial value acquisition timing”, Shall be replaced.

  In the configuration including the feature F3, “a storage unit that stores information used when the control unit performs control and stores the information while power is supplied to itself” is “ The storage means stores and holds information used when controlling the game while power is supplied to the storage means.

With
Based on the fact that the numerical information acquired by the numerical information acquisition means corresponds to predetermined winning information, a privilege is given to the player,
In the gaming machine in which the numerical information update means starts updating the numerical information from a predetermined initial value based on the output of the activation signal from the activation signal output means,

An initial value information acquisition unit (a function for executing an initial value setting process in the MPU 311) for acquiring the initial value information from the initial value information update unit based on the input of the activation signal;
With
The numerical value updating means updates the numerical value information from the acquired initial value information when the initial value information is acquired by the initial value information acquiring means. Machine.

  According to the feature F6, the initial value information is acquired based on the input of the activation signal to the initial value information acquisition unit, and the numerical information is updated from the initial value information. Since the initial value information is sequentially updated every time the update timing is reached, the initial value information acquired in accordance with the timing at which a predetermined operating condition is established varies. Thereby, since it is difficult to grasp the initial value information, it is difficult to grasp the timing at which the numerical information becomes the winning information. Therefore, fraudulent acts caused by “hanging board” or the like can be suppressed.

  Feature F7. In feature F6, a varying means (an irregular delay circuit 602 or a non-periodic circuit) that varies a period from the establishment timing of the predetermined operating condition to the acquisition timing to acquire the initial value information according to the establishment timing A gaming machine characterized by comprising:

  According to the feature F7, the period from the establishment timing of the predetermined operating condition to the initial value information acquisition timing is changed by the changing means. Thereby, since the acquired initial value information varies, the initial value information when the update of the numerical information updating unit is started varies. Therefore, it is difficult to grasp initial value information when the numerical information updating unit starts updating. Therefore, even when the timing at which a predetermined operating condition is established and the initial value information of the initial value information updating means is grasped by the “hanging board” or the like, it is difficult to grasp the timing at which the numerical information becomes the winning information. Therefore, fraudulent acts using the “hanging board” or the like can be suppressed.

  Note that the technical ideas shown in the features E5 to E18 and the features E22 to E24 can be applied to this feature. In this case, “based on the start of supply of operating power to the control unit” “based on the establishment of the predetermined operating condition” and “numerical information update unit” “initial value information” “Acquisition means”, “start update” are replaced with “obtain initial value information”, and “update start timing” are replaced with “initial value acquisition timing”.

Feature F8. Numerical information updating means for sequentially updating numerical information in a predetermined numerical range every time the update timing comes (function to execute the update process of the big hit random number counter C1 in step S703 in the MPU 311);
Based on the establishment of a predetermined acquisition condition, numerical information acquisition means for acquiring numerical information updated by the numerical information update means (a process of storing the big hit random number counter C1 in step S804 in the MPU 311 is executed). Function)

With
Based on the fact that the numerical information acquired by the numerical information acquisition means corresponds to predetermined winning information, a privilege is given to the player,
In the gaming machine that starts updating the numerical information from a predetermined initial value based on the initial value setting operation being received by the receiving means,

With
The numerical value updating means updates the numerical value information from the acquired initial value information when the initial value information is acquired by the initial value information acquiring means. Machine.

  According to the feature F8, when the initial value setting operation is received by the receiving unit, the initial value information is acquired, and the numerical information is sequentially updated from the acquired initial value information. Since the initial value information is updated, the initial value information acquired for each initial value setting operation varies. Thereby, it is difficult to grasp the timing at which the numerical information becomes the winning information based on the initial value setting operation. Therefore, fraudulent acts such as “hanging board” can be suppressed.

  Feature F9. In feature F8, the fluctuating means (irregular delay circuit) that varies the period from when the accepting means accepts the initial value setting operation until the initial value information is acquired, according to the acceptance timing of the initial value setting operation. 602 or a non-periodic circuit).

  According to the feature F9, since the period from the reception timing of the initial value setting operation to the acquisition timing for acquiring the initial value information varies depending on the reception timing, until the initial value information is acquired after the initial value setting operation is received. Variation occurs in the period. Thereby, the period from the initial value setting operation reception timing to the initial value information acquisition timing becomes irregular. Therefore, even if the initial value information of the initial value information updating means is grasped by “hanging board” or the like, the period from the initial value setting operation reception timing until the numerical information matches the winning information is grasped. Hateful. Therefore, the “hanging board” or the like can suppress an illegal act of illegally obtaining a privilege by outputting a signal in accordance with the timing when the numerical information coincides with the winning information.

  In addition, it is possible to apply the technical idea shown in the features E5 to E18 and the features E22 to E24 to this feature. In this case, “based on the start of supply of operating power to the control means” “based on accepting the initial value setting operation” and “numerical information update means” Replace “value information acquisition means”, “start update” with “acquire initial value information”, and “update start timing” with “initial value acquisition timing”.

  Each invention of the said characteristic F group is effective with respect to the following subjects.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Whether or not the big hit state has occurred is determined at the timing when the game ball enters the operation port. For example, it is equipped with a counter that is periodically updated within a certain range (for example, updated every 1 ms in the range of 0 to 300 every 2 ms), and obtains the value of the counter when the game ball enters the operation port Then, when the value of the counter coincides with a predetermined value such as “7”, for example, a privilege that the gaming state shifts to the jackpot state is given to the player.

  Here, an illegal act using an illegal substrate called “hanging substrate” may be performed. The fraudulent act is to illegally generate a jackpot state by hanging an unauthorized substrate with respect to a regular control substrate. Specifically, a counter that is synchronized with the counter used in the jackpot lottery is provided on the “hanging board”, and the value of the counter is reset to “0” when the pachinko machine is turned on, etc. Understand the timing of the occurrence of jackpot status. Then, in accordance with the occurrence timing of the jackpot state, an illegal entry detection signal is output from the “hanging board” to the regular control board, and the jackpot state is illegally generated.

  On the other hand, a gaming machine that changes the initial value of the counter update every time the counter used in the jackpot lottery is updated is conceivable. According to the gaming machine, since the initial value of the counter update is changed every time the counter is rotated, it is difficult to grasp the occurrence timing of the jackpot by the “hanging board”. Further, separately from the periodic update process, the initial value to be changed cannot be grasped by performing the update process of the initial value random number counter in the remaining time of a predetermined loop process for performing game control.

  However, even with such a configuration, when the control board is initialized when recovering from a power failure or when the RAM is cleared, information such as the values of various counters stored in the storage means such as the RAM is cleared. Therefore, immediately after initialization, the value of the random number counter used in the jackpot lottery or the initial value random number counter used when determining the initial value of the random number counter is set to a predetermined value such as “0”, for example.

As a result, variations occur in the period from when the predetermined condition is satisfied to the input timing, and the period becomes irregular. Therefore, since it is difficult to grasp the period from the establishment timing of the predetermined condition to the timing when the numerical information becomes the winning information, even if the establishment timing of the predetermined condition is grasped, it is difficult to grasp the timing when the numerical information becomes the winning information.

Here, a fluctuating means is provided at an intermediate position in the supply path, and the period from the timing when the supply state is reached to the timing when the operation becomes possible varies depending on the timing when the supply state is reached. As a result, the period from the timing when the supply state is reached until the operation becomes possible becomes irregular, so the update start timing when updating of the numerical information starts from the supply start timing when power is supplied to the power means. The period until is irregular. Therefore, since the period from the supply start timing until the numerical information becomes the winning information becomes irregular, it is difficult to grasp the period.

  Each invention of the above-mentioned feature group G is effective for the following problems.

  One type of gaming machine is a pachinko machine. In a pachinko machine, for example, a big hit lottery is performed based on a game ball launched into a game area entering a working port. When winning the occurrence of the big hit state in the lottery, for example, after the symbols that are variably displayed on a predetermined display device are stopped and displayed in a predetermined combination, the variable pitching device provided in the game area is opened and closed. Executed. Then, a privilege is given to the player such that game balls corresponding to the number of balls entered into the variable pitching device are paid out.

  Whether or not the big hit state has occurred is determined at the timing when the game ball enters the operation port. For example, it is equipped with a counter that is periodically updated within a certain range (for example, updated every 1 ms in the range of 0 to 300 every 2 ms), and obtains the value of the counter when the game ball enters the operation port Then, when the value of the counter coincides with a predetermined value such as “7”, for example, a privilege that the gaming state shifts to the jackpot state is given to the player.

  Here, an illegal act using an illegal substrate called “hanging substrate” may be performed. The fraudulent act is to illegally generate a jackpot state by hanging an unauthorized substrate with respect to a regular control substrate. Specifically, a counter that is synchronized with the counter used in the jackpot lottery is provided on the “hanging board”, and the value of the counter is reset to “0” when the pachinko machine is turned on, etc. Understand the timing of the occurrence of jackpot status.

  On the other hand, a gaming machine that changes the initial value of the counter update every time the counter used in the jackpot lottery is updated is conceivable. According to the gaming machine, since the initial value of the counter update is changed every time the counter is rotated, it is difficult to grasp the occurrence timing of the jackpot by the “hanging board”. Further, separately from the periodic update process, the initial value to be changed cannot be grasped by performing the update process of the initial value random number counter in the remaining time of a predetermined loop process for performing game control.

  However, even with such a configuration, when the control board is initialized when recovering from a power failure or when the RAM is cleared, information such as the values of various counters stored in the storage means such as the RAM is cleared. Therefore, immediately after initialization, the value of the random number counter used in the jackpot lottery or the initial value random number counter used when determining the initial value of the random number counter is set to a predetermined value such as “0”, for example. Is done. As a result, immediately after the initialization of the control board, the occurrence timing of the jackpot may be easily grasped by the “hanging board”. Therefore, it is conceivable to carry out an initialization process and perform an illegal act that generates a jackpot.
