Description

  The present invention relates to a game table represented by a ball game machine (pachinko machine) and a spinning machine (slot machine).

  In a game stand represented by a ball ball game machine (pachinko machine) or a spinning machine game machine (slot machine), a random number is obtained, a lottery is performed using the obtained random number, and a player is determined based on the result of the lottery. There are things that may or may not be advantageous. Random number processing such as acquiring random numbers and performing lottery using the acquired random numbers is often performed by a main control unit that controls the entire game machine. The main control unit includes a CPU (Central Processing Unit) that performs calculations and a calculation storage unit that stores calculation results by the CPU. In addition, many game machines are equipped with various electrical components. In recent game machines, an electrical component control unit for controlling these various electrical components is provided separately from the main control unit. Similarly to the main control unit, the electric component control unit also includes a CPU and calculation storage means, and various commands are transmitted to the electric component control unit from the main control unit.

In a game store where a game machine is installed, usually, before the store is opened, the power operation element is operated from OFF to ON, and supply of drive power to the game machine is started (power is turned on). When the power is turned on in this way, it is common to initialize the arithmetic storage means provided in each of the main control unit and the electrical component control unit. That is, an initialization process is performed to set the address value of the area to be initialized in the arithmetic storage means to a specific value. When the initialization process in the main control unit is completed, command transmission to the electric component control unit is started. However, if the initialization process in the electric component control unit is not completed, the electric component control unit The command sent from the control unit cannot be received. Therefore, a gaming machine has been proposed in which the command transmission start timing of the main control unit is delayed by a predetermined time so that the electric component control unit can reliably receive the command (see Patent Document 1).
JP 2001-347028 A

  By the way, when the power operator is turned on before the store is opened and the supply of driving power to the game machine is started, the power operator remains on until the store is closed. Therefore, while the amusement store is operating, it is normal for drive power to be continuously supplied to the game machine. However, if an overvoltage is applied to the game machine, the game machine will have a protective function that shuts off the power (power supply ) After the game is turned off, the power will be restored (power will be turned on). However, the fact that most of the game machines are powered off is not caused by overvoltage but by fraud. . Even when the power is cut off and power is restored, the main control unit may execute the initialization process.

  In the main control unit, the random number process is performed after the initialization process is completed. Some of those who try to cheat will cause the main control unit to turn off the power illegally so that the initialization process is executed. Some people try to obtain random numbers illegally, aiming for the acquisition timing. According to the gaming machine described in Patent Document 1, since the time required for the delay process is constant, those timings executed after the initialization process are also constant, and these timings are targeted.

  One of the conditions here means that there may be other conditions, there may be no other conditions, and only the conditions mentioned here may be used (hereinafter the same).

Further, the control means includes a return flag on / off processing unit that sets a non-volatile return flag indicating whether or not a power cut has occurred to an on / off state when a power cut occurs during the game. A return flag determination processing unit that determines the state of the return flag when the power is turned on,
When the power is turned on, the initialization processing unit is based on the condition that the return flag determination processing unit determines that the state of the return flag is a state in which no power interruption occurs during the game. The initialization process may be started.

  The non-volatile return flag only needs to be provided in the control means. For example, the non-volatile return flag may be provided in a register of the CPU, or provided in a partial area of the arithmetic storage means. It may be.

Furthermore, the control means includes a checksum determination processing unit that determines whether or not there is an abnormality in the checksum of the predetermined area in the arithmetic storage means when the power is turned off,
When the power is turned on, the initialization processing unit starts the initialization processing on the condition that the checksum determination processing unit determines that the checksum is abnormal. Also good.

  The checksum determination processing unit may determine whether or not there is an abnormality in the checksum when power is turned on, or perform the determination when power is interrupted and store the determination result in a nonvolatile storage area. You may evacuate.

Note that other storage means may be used for the ROM 306 and the RAM 308, and this is the same for the sub-control unit 400 described later. The CPU 304 of the basic circuit 302 operates by inputting a clock signal of a predetermined period output from the crystal oscillator 314b as a system clock.

  Further, the basic circuit 302 includes a counter circuit 316 used as a hardware random number counter that changes a numerical value in the range of 0 to 65535 every time a clock signal output from the crystal oscillator 314a is received (this circuit has 2 Each counter), and signals output from various sensors 318 including a ball detection sensor provided inside each start opening, winning opening and variable winning opening, and receiving amplification results and reference A sensor circuit 320 for outputting a comparison result with the voltage to the counter circuit 316 and the basic circuit 302, a display circuit 322 for performing display control of the special figure display device 114, and performing display control of the general map display device 112. Display circuit 324 and various status display units 326 (general map hold lamp 116, special figure hold lamp 118, high accuracy medium lamp 118, etc.) A display circuit 328 for performing, connects the solenoid circuit 332 for controlling the solenoids 330 for opening and closing the second Japanese view start hole 128 and the variable winning hole 130 or the like.

  When the ball detection sensor 318 detects that a ball has won the first special figure starting port 126, the sensor circuit 320 outputs a signal indicating that the ball has been detected to the counter circuit 316. Upon receiving this signal, the counter circuit 316 latches the value of the counter corresponding to the first special figure starting port 126 at that timing, and stores the latched value in the built-in counter value corresponding to the first special figure starting port 126. Store in the register. Similarly, when the counter circuit 316 receives a signal indicating that the ball has won the second special figure starting port 128, the counter circuit 316 latches the value at the timing of the counter corresponding to the second special figure starting port 128. The latched value is stored in a built-in counter value storage register corresponding to the second special figure starting port 128.

  Further, an information output circuit 334 is connected to the basic circuit 302, and the main control unit 300 is connected to an information input circuit 652 provided in an external game shop computer (not shown) or the like via the information output circuit 334. The game information (for example, game state) of the pachinko machine 100 is output.

  The main control unit 300 is provided with a voltage monitoring circuit 336 that monitors the voltage value of the power source supplied from the power management unit 650 to the main control unit 300. The voltage monitoring circuit 336 is a voltage value of the power source. Is less than a predetermined value (9v in this embodiment), a low voltage signal indicating that the voltage has dropped is output to the basic circuit 302.

  Further, as described above, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 338 that outputs a start signal (reset signal) when the power is turned on. When an activation signal is input from the signal output circuit 338, game control is started (main control unit main processing described later is started).

  The main control unit 300 includes an output interface for transmitting a command to the sub-control unit 400 and an output interface for transmitting a command to the payout control unit 550. With this configuration, the sub-control unit 400 In addition, communication with the payout control unit 550 is enabled. Information communication between the main control unit 300, the sub control unit 400, and the payout control unit 550 is one-way communication, and the main control unit 300 can transmit signals such as commands to the sub control unit 400 and the payout control unit 550. However, the sub-control unit 400 and the payout control unit 550 are configured such that signals such as commands cannot be transmitted to the main control unit 300.

<Sub control unit>
Next, the sub control unit 400 of the pachinko machine 100 will be described.

  The sub-control unit 400 includes a basic circuit 402 that controls the entire sub-control unit 400 mainly based on commands transmitted from the main control unit 300. The basic circuit 402 includes a CPU 404, a control program, ROM 406 for storing various data, RAM (RWM) 408 for temporarily storing data, I / O 410 for controlling input / output of various devices, and for measuring time and frequency A counter timer 412 is mounted. The CPU 404 of the basic circuit 402 operates by inputting a clock signal of a predetermined period output from the crystal oscillator 414 as a system clock.

  The basic circuit 402 drives a sound source IC 418 for controlling the speaker 416 (and amplifier), a display circuit 422 for controlling various lamps 420, a movable body for rendering of the rendering device 200, and the like. An effect driving device control circuit 426 for controlling various effect driving devices 424 including a solenoid or a motor as a driving device, and a decorative symbol display device (liquid crystal display device) 110 and a shielding means 250 are controlled. The decorative symbol display control unit 500 is connected to the chance button detection circuit 380 that detects the pressing of the chance button 146 and outputs a signal.

<Discharge control unit, launch control unit, power supply management unit>
Next, the payout control unit 550, the launch control unit 600, and the power supply management unit 650 of the pachinko machine 100 will be described.

  The payout control unit 550 controls the payout device 552 mainly based on a signal such as a command transmitted from the main control unit 300, and the payout of the winning ball or the rental ball is completed based on a control signal output from the payout sensor 554. It is detected whether or not the card unit 654 is provided separately from the pachinko machine 100 via the interface unit 556.

  The firing control unit 600 determines the amount of operation of the launch handle 148 by the player, which is output from the control signal instructing permission or stop of launch output from the payout control unit 550, or the launch intensity output circuit provided in the operation handle 148. Based on the control signal instructing the corresponding launch intensity, the launch motor 602 that drives the launcher 138 and the launcher 140 is controlled, and the ball feeder 604 that supplies the ball from the storage plate 144 to the launch rail 142 is controlled. .

  The power management unit 650 converts the AC power supplied from the outside to the pachinko machine 100 into a direct current, converts it into a predetermined voltage, and controls the control units such as the main control unit 300 and the sub control unit 400, and the devices such as the dispensing device 552. To supply. Further, the power management unit 650 supplies a power storage circuit (for example, a power supply circuit) for supplying power to a predetermined part (for example, the RAM 308 of the main control unit 300) for a predetermined period (for example, 10 days) even after the external power supply is cut off. Capacitor).

<Main control unit main processing>
Next, main control unit main processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  As described above, the main control unit 300 is provided with the start signal output circuit (reset signal output circuit) 338 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input starts reset by a reset interrupt and executes main control unit main processing shown in FIG. 6 according to a control program stored in advance in the ROM 306. The case where the power is turned on includes a case where the power switch 1621 shown in FIG. 2 is operated from off to on to start supplying driving power to the pachinko machine 100, or for some reason while the power switch 1621 is in the on state. There are cases where power is restored after a power interruption (power interruption). Normally, a game store has a centralized power switch (not shown) for each island, and when the centralized power switch is turned on / off, the pachinko machine 100 installed on the island is supplied with driving power / It is possible to stop all at once. Therefore, the pachinko machine 100 is also turned on by turning on the central power switch.

  In step S101, initial setting 1 is performed. In this initial setting 1, setting of a stack initial value (temporary setting) to the stack pointer (SP) of the CPU 304, setting of an interrupt mask, initial setting of the I / O port 310, initial setting of various variables stored in the RAM 308, WDT 313 Allow operation and set initial values. In this embodiment, a numerical value corresponding to 32.8 ms is set as an initial value in WDT 313.

  In step S102, the value of the counter of WDT 313 is cleared, and the time measurement by WDT 313 is restarted.

  In step S103, whether or not the low voltage signal is on, that is, the voltage value of the power supply that the voltage monitoring circuit 336 supplies from the power management unit 650 to the main control unit 300 is a predetermined value (in this embodiment, 9v), it is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. If the low voltage signal is on (when the CPU 304 detects that the power supply has been shut off), the process returns to step S102. If the low voltage signal is off (if the CPU 304 has not detected the power supply being cut off), the process proceeds to step S102. The process proceeds to S104. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, the process returns to step S102, and step S103 is repeatedly executed until the supply voltage exceeds the predetermined value.

  In step S104, initial setting 2 is performed. In this initial setting 2, a process for setting a numerical value for determining a cycle for executing a main control unit timer interrupt process, which will be described later, to the counter / timer 312, a predetermined port of the I / O 310 (for example, a test output port, Processing for outputting a clear signal from the output port to the sub-control unit 400, setting for permitting writing to the RAM 308, and the like are performed.

  In step S1051 to step S1053, it is determined whether or not to return to the state before the power interruption (before power interruption). If the state before the power interruption does not return (the basic circuit 302 of the main control unit 300 is initialized). If YES, the process proceeds to initialization processing (step S107).

  Specifically, first, in step S1051, a RAM clear signal transmitted when a store clerk or the like of a game store operates the RAM clear switch 1623 provided on the power supply board 162 shown in FIG. If the RAM clear signal is on (RAM clear is necessary), the basic circuit 302 is set to the initial state. Therefore, the process proceeds to step S107. On the other hand, when the RAM clear signal is off (when the RAM clear is not necessary), the process proceeds to step S1052. The CPU 306 of the main control unit 300 that executes step S1051 corresponds to an example of an operation determination processing unit according to the present invention.

  In step S1052, it is determined whether the return flag provided in the RAM 308 is off. The CPU 306 of the main control unit 300 that executes step S1052 corresponds to an example of a return flag determination processing unit according to the present invention. The return flag is prepared in a non-volatile area provided in the RAM 308 of the main control unit 300, and is set (turned on) in a power interruption process that is executed when a power cutoff is detected, which will be described later. If the return flag is off, the process proceeds to step S107 to set the basic circuit 302 to the initial state. If the return flag is on, the process proceeds to step S1053.

  Further, in the power interruption process described later in detail, the checksum calculation value in the RAM 308 immediately before the power interruption is saved in a nonvolatile checksum saving area. In step S1053, a checksum is calculated by adding all 1-byte data stored in a predetermined area of the RAM 308 (for example, all areas excluding the nonvolatile area) to a 1-byte register whose initial value is 0. Whether or not the checksum calculation value calculated here is inconsistent with the checksum calculation value before power interruption saved in the non-volatile checksum save area (the checksum result is abnormal) Whether or not). The CPU 306 of the main control unit 300 that executes step S1053 corresponds to an example of a checksum determination processing unit according to the present invention. If the checksum calculation values do not match (if the checksum result is abnormal), the process proceeds to step S107 to set the pachinko machine 100 to the initial state, and if the checksum calculation values match (check If the result of the thumb is normal), the process proceeds to step S106 to return to the state before the power interruption.

  In step S106, power recovery processing is performed. In this power recovery process, the value of the stack pointer stored in the stack pointer save area provided in the RAM 308 at the time of power interruption is read and reset to the stack pointer (this setting). In addition, the value of each register stored in the register save area provided in the RAM 308 at the time of power interruption is read out, reset to each register, and then the interrupt permission is set. Thereafter, as a result of the CPU 304 executing the control program based on the reset stack pointer and registers, the pachinko machine 100 returns to the state when the power is turned off. That is, the processing is resumed from the instruction next to the instruction (predetermined in steps S108 and S109) performed immediately before branching to the timer interrupt processing (described later) immediately before the power interruption. In addition, a transmission information storage area is provided in the RAM 308 mounted on the basic circuit 302 in the main control unit 300 shown in FIG. In step S106, EH is set as a power recovery command in the transmission information storage area. This power recovery command is a command indicating that the power has been restored to the state at the time of power-off, and is transmitted to the sub-control unit 400 in step S215 in the timer interrupt process of the main control unit 300, which will be described later.

  In step S107, initialization processing (details will be described later) is performed. Therefore, in this embodiment, it is determined that the RAM clear switch 1623 has been operated (step S1051), and it is determined that the state of the return flag is a state in which no power interruption occurs during the game (the return flag is off). (Step S1052) and the fact that it is determined that there is an abnormality in the checksum (Step S1053), the initialization process of Step S107 is started. A person who attempts to obtain a random number value illegally caused the power supply to be cut off in such a manner that the initialization process is executed by satisfying any of the three determination conditions such as step S1051 to step S1053 in the main control unit. It is very difficult to illegally acquire a random value by an initialization process described later.

  In step S108, after setting for interrupt inhibition, basic random number initial value update processing is performed. In this basic random number initial value update process, two initial value generation random number counters for generating the initial values of the normal figure winning random number counter and the special figure random value counter, the normal figure timer random number value, and the special figure timer random number counter, respectively. Two random number counters for generating numerical values are updated. For example, if the range of values that can be taken as normal timer random numbers is 0 to 20, a value is acquired from a random number counter storage area for generating a normal timer random value provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 21, 0 is stored in the original random number counter storage area. Other initial value generation random number counters and random number counters are similarly updated. Further, after this basic random number initial value update process is completed, an interrupt permission is set, and the process proceeds to step S109.

  In step S109, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated.

  The main control unit 300 repeatedly executes the processes of steps S108 and S109 except during a timer interrupt process that starts every predetermined period.

<Initialization process>
Next, the initialization process (step S107) in the main control unit main process will be described in detail with reference to FIG. This figure is a flowchart showing the flow of initialization processing.

  First, various setting processes such as setting of interrupt inhibition and setting of a stack initial value to the stack pointer (this setting) are performed (step S1071). In addition, the RAM 308 of the main control unit 300 generates a random number counter storage area for generating a value of a common winning random number, which is one of software random numbers, and a special figure random number, which is another software random number. A random number counter storage area is provided. In step S1071, a predetermined initial value (for example, 0) is set in each of the random number counter storage areas. Furthermore, the counter value storage registers corresponding to the first special figure starting port 126 and the second special figure starting port 128, which are registers of the counter circuit 316 (see FIG. 5) used as a hardware random number counter, are also used. A predetermined initial value is set.

  Next, the start address of the area (area) to be initialized in the RAM 308 provided in the main control unit 300 is acquired (step S1072). A partial area of the RAM 308 of the main control unit 300 is a non-volatile area. In this embodiment, all areas of the RAM 308 except for the non-volatile area are areas to be initialized. In step S1073, it is determined whether or not the value (content value) of the acquired address is 0. If it is 0, the process proceeds to step S1074. On the other hand, if the acquired address value is not 0, 1 is subtracted from the content value (step S1075), and the process returns to step S1073. Therefore, step S1075 is repeatedly executed until the content value of the acquired address becomes 0.

  In step S1074, it is determined whether or not the acquired address is the final address of the area (area) to be initialized. If the acquired address is the final address, the process proceeds to the basic random number initial value update process in step S108 shown in FIG. On the other hand, if the acquired address is not the final address, 1 is added to the acquired address (step S1076), and the process returns to step S1073.

  The CPU 306 of the main control unit 300 that executes the initialization process shown in FIG. 7 described above corresponds to an example of the initialization processing unit according to the present invention. According to this initialization process, the number of executions of step S1075 varies depending on the content value of the acquired address, and the time required for the initialization process varies depending on the initialization process. As a result, the software random number update timing and hardware random value acquisition timing, which will be described later, executed after the initialization process become random, and attempts to illegally acquire random values aiming at these timings Becomes difficult.

  In this embodiment, the RAM 308 is initialized. However, the present invention can also be applied to the case where the register included in the CPU 304 is initialized.

  In the present embodiment, an example is shown in which 1 is subtracted from the content value as a predetermined calculation when the content value of the acquired address is not 0. However, a predetermined value other than 1 may be subtracted. They may be added one by one, or multiplication or division may be performed. Furthermore, although the example in which the predetermined calculation is repeated until 0 is shown, it may be repeated until a predetermined value other than 0 is reached.

<Main controller timer interrupt processing>
Next, the main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main controller timer interrupt processing.

  The main control unit 300 includes a counter / timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms), and the main control unit timer interrupt processing is triggered by this timer interrupt signal. Start with a predetermined period.

  In step S201, timer interrupt start processing is performed. In this timer interrupt start process, a process of temporarily saving the value of each register of the CPU 304 to the stack area is performed.

  In step S202, WDT is periodically performed (this implementation is performed so that the WDT interrupt does not occur (the processing abnormality is not detected)) because the count value of WDT 313 exceeds the initial setting value (32.8 ms in this embodiment). In the example, the restart is performed once in about 2 ms which is the period of the main control unit timer interrupt.

  In step S203, input port state update processing is performed. In this input port state update process, detection signals from various sensors 318 including a glass frame open sensor, a front frame open sensor, a lower pan full sensor, and a plurality of ball detection sensors are input via the input port of the I / O 310. The presence / absence of a detection signal is monitored and stored in a signal state storage area provided for each sensor 318 in the RAM 308. If the detection signal of the sphere detection sensor is described as an example, in this embodiment, information on the presence / absence of the detection signal of each sphere detection sensor detected in the timer interruption process (about 4 ms before) is stored in the RAM 308 in each RAM 308. This is read from the previous detection signal storage area provided for each sphere detection sensor, and this information is stored in the RAM 308 in the previous detection signal storage area provided for each sphere detection sensor. Information about the presence / absence of the detection signal of each sphere detection sensor detected about 2 ms before) is read from the current detection signal storage area provided for each sphere detection sensor in the RAM 308, and this information is detected as described above. Store in the signal storage area. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

  In step S203, the information on the presence / absence of the detection signal of each sphere detection sensor stored in each storage area of the detection signal storage area, the previous detection signal storage area, and the current detection signal storage area is compared. It is determined whether or not the information on the presence / absence of detection signals for the past three times in the sphere detection sensor of the two sphere detection sensors matches. The information on the presence or absence of detection signals for the past three times in each sphere detection sensor is predetermined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, this time detection signal) In the case of a match to the winning opening (the general winning opening 122, the variable winning opening 130) or the starting opening (the first special figure starting opening 126, the second special drawing starting opening 128), It is determined that the starting port 124 has passed. For example, if the information on the presence / absence of detection signals for the past three matches with the above-described winning determination pattern information in the ball detection sensor that detects the winning at the general winning opening 122, it is assumed that the player has entered the general winning opening 122. After determining and performing the process associated with the subsequent entry to the general winning opening 122, if the information on the presence or absence of the detection signals for the past three times does not match the above-described winning determination pattern information, The process branches to the subsequent process without performing the process associated with entering the mouth 122.

  In step S204 and step S205, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the value of the initial value generation random number counter performed in step S108 is updated, and then the normal winning random number value and special value used in the main control unit 300 are updated. The two random number counters for generating the figure random number values are updated. For example, if the range of values that can be taken as a random number value for a normal winning number is 0 to 100, a value is acquired from a random number counter storage area for generating a normal winning random number value provided in the RAM 308 and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. That is, the software random number is updated. In the first main control unit timer interrupt process executed after the power is turned on and the initialization process shown in FIG. 7 is performed, the value acquired from the random number counter storage area in this step S205 becomes an initial value (for example, 0), A value obtained by adding 1 to the initial value becomes an updated random value. Therefore, the CPU 306 of the main control unit 300 that executes step S205 corresponds to an example of a random number generation unit according to the present invention. Here, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set. For example, a value is acquired from a random number counter for generating a regular winning random number that fluctuates in a numerical range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 308. If the value is equal to the previously set initial value (for example, 7), the value is acquired as an initial value from the initial value generation random number counter corresponding to the random number counter for generating the random number for winning the normal number, The initial value set this time is stored in the above-described initial value storage area in order to determine that the random number counter for generating the winning random number value has made one round next time, in addition to setting it in the random number counter for generating the winning random value Keep it. In addition to the above-described initial value storage area for determining that the random number counter for generating the regular-winning random number next makes one round, it is determined that the random number counter for generating the special figure random number has made one round. An initial value storage area is provided in the RAM 308.

  Here, among those who intend to perform an illegal act, the power is cut off illegally so that the initialization process is executed in the main control unit, and the timing is updated in the basic random number update process in step S205. There is a person who tries to get the software random number value. As described above, when step S1071 of the initialization process shown in FIG. 7 is executed, a random number counter storage area for generating a normal winning random number value provided in the RAM 308 and a special figure random number value are generated. An initial value is set in each of the random number counter storage areas, and it becomes easy for an unauthorized person to illegally acquire a software random number value. However, in this embodiment, since the time required for the initialization process varies as described above, the timing of the basic random number update process in step S205 becomes random, and the fraudster follows the process timing in step S205. It becomes difficult to obtain software random numbers. As a result, an illegal act of illegally generating a gaming state advantageous to the player is prevented.

  In step S206, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated.

  In step S207, timer update processing is performed. As will be described in detail later, in this timer update process, the normal symbol display symbol update device for measuring the time for the symbol to be changed / stopped on the normal symbol display device 112, and the symbol to be changed / stopped to be displayed on the special symbol display device 114. Various timers including a special figure display symbol update timer for timing the time to perform, a timer for timing a predetermined winning effect time, a predetermined opening time, a predetermined closing time, a predetermined end effect period, etc. are updated. .

  In step S208, winning prize counter updating processing is performed. In this winning opening counter updating process, when there is a winning (winning) in the winning opening (the general winning opening 122, the first and second special figure starting openings 126, 128, and the variable winning opening 130), The value of the winning ball number storage area provided for each winning opening is read, and 1 is added to set the original winning ball number storage area.

  In step S209, a winning acceptance process is performed. In this winning acceptance process, if there is a prize at the first and second special figure starting ports 126 and 128 and the number of special figure variable games held is less than four, it corresponds to the winning starting port. The value is acquired from the counter value storage register of the counter circuit 316 to be a special figure winning random number value. In the first main control unit timer interrupt process executed after the power is turned on and the initialization process shown in FIG. 7 is performed, the special figure winning random number value acquired in step S209 is the initial value of the counter value storage register. become. That is, when step S1071 of the initialization process shown in FIG. 7 is executed, an initial value is also set in the counter value storage register of the counter circuit 316 used as a hardware random number counter (see FIG. 5). For the fraudster, the hardware random number value is also easily obtained illegally. However, in this embodiment, since the time required for the initialization process varies as described above, the timing of the winning acceptance process in step S209 is also random, and the fraudulent acts hard at the timing of the process in step S209. It is also difficult to acquire a wear random number value. As a result, again, illegal acts such as illegally generating a gaming state advantageous to the player are prevented. In addition, a value is acquired as a special figure random value from the random number counter for generating the special figure random value described above, and stored in a random value storage area provided in the RAM 308 together with the special figure winning random number value. In addition, when it is detected that the ball has passed through the general figure starting port 124, and the number of the general figure variable games held is less than two, the random number counter for generating the normal figure winning random number value at that timing Is obtained as a random number value for normal winning, and is stored in a random number value storage area provided in the RAM 308 different from that for the above special figure. In this winning acceptance process, if a predetermined ball detection sensor detects a winning (winning) at the first and second special figure starting ports 126, 128, the ordinary starting port 124, or a variable winning port, In the transmission information to be transmitted to the control unit 400, winning acceptance information indicating presence / absence of winning (winning) of the first and second special figure starting ports 126 and 128, the universal drawing starting port 124, and the variable winning port is set. .

  In step S210, a payout request number transmission process is performed. The output schedule information and the payout request information output to the payout control unit 550 are composed of 1 byte, strobe information in bit 7 (indicating that data is set when on), and power supply in bit 6 Input information (indicating that it is the first command transmission after power-on when turned on), bits 4-5 for the current processing type for encryption (0-3), and bits 0-3 for encryption processing The number of subsequent payout requests is indicated.

  In step S211, a normal state update process is performed. This normal state update process performs one of a plurality of processes corresponding to the normal state. For example, in a general diagram state update process during a normal map change (the value of the above-mentioned general map display symbol update timer is 1 or more), the 7 segment LED constituting the general map display device 112 is repeatedly turned on / off. Take control.

  Further, in the general chart state update process at the timing when the normal map change display time has elapsed (the timing when the value of the general map display symbol update timer has changed from 1 to 0), when the hit flag is on, FIG. When the 7-segment LED constituting the universal display device 112 is controlled to be turned on / off so as to be in the form shown in FIG. 1 and the hit flag is off, the normal figure shown in FIG. In the RAM 308, in order to maintain the display for a predetermined stop display period (for example, 500 msec), the 7-segment LED constituting the ordinary display device 112 is controlled to be turned on / off so as to be in the second mode. In addition, information indicating the stop period is set in the storage area of the normal stop time management timer. With this setting, the usual figure is stopped and the result of the usual figure variable game is notified to the player.

  Further, in the normal state update process that starts at the timing when the predetermined stop display period ends (when the value of the normal stop time management timer value changes from 1 to 0), if the hit flag is on, the predetermined state is displayed. During the opening period (for example, 2 seconds), a signal for holding the blade member in an open state is output to the solenoid 330 for opening and closing the blade member of the second special figure starting port 128, and the blade opening time management provided in the RAM 308 is controlled. Information indicating the release period is set in the storage area of the timer.

  In the usual state update process that starts at the timing when the predetermined opening period ends (the timing when the value of the blade opening time management timer is changed from 1 to 0), the blade member has a predetermined closing period (for example, 500 milliseconds). A signal for holding the blade member in a closed state is output to the opening / closing drive solenoid 330, and information indicating the closing period is set in the storage area of the blade closing time management timer provided in the RAM 308.

  In the normal state update process that starts at the timing when a predetermined closing period has elapsed (the timing when the value of the blade closing time management timer changes from 1 to 0), the normal state is set to inactive. In the normal state update process when the normal state is inactive, the process proceeds to the next step S212 without doing anything.

  In step S212, a general drawing related lottery process is performed. In this general map-related lottery process, the open / close control of the general map variable game and the second special map start port 128 is not performed (the state of the general map is not in operation), and the pending general map variable game is not held. When the number is 1 or more, it is decided whether to win or not to win the result of the variable figure game by random lottery based on the random number value stored in the random number value storage area. When the winning judgment is made and the winning is made, the winning flag provided in the RAM 308 is set to ON. If unsuccessful, turn off the winning flag. Regardless of the result of the hit determination, next, the value of the random number counter for generating the normal figure timer random value is acquired as the normal figure timer random number value, and a plurality of fluctuation times are obtained based on the acquired general figure timer random number value. One time for displaying the variable map on the general map display device 112 is selected from among them, and this variable display time is stored in the general map variable time storage area provided in the RAM 308 as the normal map variable display time. In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308, and from the number of pending custom figure variable games each time a hit determination is made. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area. Also, the random number value used for the hit determination is deleted.

  In step S213, special figure state update processing is performed. In the special figure state update process, one of the following eight processes is performed according to the state of the special figure. For example, in special figure state update processing during special figure fluctuation (the above-mentioned special figure display symbol update timer value is 1 or more), lighting / extinguishing driving that repeatedly turns on and off the 7-segment LED constituting the special figure display device 112 Take control.

  Also, in the special figure state update process that starts at the timing when the special figure change display time has elapsed (when the special figure display symbol update timer value changes from 1 to 0), the jackpot flag is on and the probability change flag is off When the special figure display device 114 has the special figure 1 shown in FIG. 4A and the jackpot flag is on and the probability variation flag is on, the special figure display device 114 has the special figure 2 shown in FIG. When the flag is OFF, the 7 segment LED constituting the special figure display device 112 is controlled to be turned on / off so that the special figure display device 112 shown in FIG. In order to maintain the display period (for example, 500 milliseconds), information indicating the stop period is set in the storage area of the special figure stop time management timer provided in the RAM 308. With this setting, the special figure is stopped and displayed, and the result of the special figure variable game is notified to the player. In addition, 4H is additionally stored as transmission information (command type) in the transmission information storage area described above in order to execute the general command rotation stop setting transmission process in the command setting transmission process (step S215).

  Further, in the special figure state update process that starts at the timing when the predetermined stop display period ends (the timing at which the special figure stop time management timer value changes from 1 to 0), if the jackpot flag is on, a predetermined value is displayed. A special figure waiting time management timer provided in the RAM 308 for waiting for a period during which an image for notifying the player that a big hit by the decorative symbol display device 110 is started, that is, a bonus winning period (for example, 3 seconds) is displayed. Information indicating the winning effect period is set in the storage area. Further, 5H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command winning effect setting transmission process in the command setting transmission process (step S215).

  Also, in the special figure state update process that starts at the timing when the predetermined winning effect period ends (the timing when the special figure standby time management timer value changes from 1 to 0), a predetermined release period (for example, 29 seconds or A signal for holding the door member in an open state is output to the solenoid 330 for opening and closing the door member of the variable prize opening 130 (until a winning of a game ball of a predetermined number (for example, 10 balls) is detected in the variable prize opening 130). At the same time, information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. Further, 7H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening release setting transmission process in the command setting transmission process (step S215).

  In the special figure state update process that starts at the timing when the predetermined opening period ends (the timing when the door opening time management timer value changes from 1 to 0), the predetermined closing period (for example, 1.5 seconds) is variable. A signal for holding the door member in the closed state is output to the solenoid 330 for opening and closing the door member of the winning opening 130, and information indicating the closing period is set in the storage area of the door closing time management timer provided in the RAM 308. To do. Further, 8H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening closing setting transmission processing in the command setting transmission processing (step S215).

  Further, in the special figure state update processing which is repeated at predetermined timing (for example, 15 rounds) and the opening / closing control of the door member is repeated a predetermined number of times (for example, 15 rounds), Information indicating the effect standby period is set in the storage area of the effect standby time management timer provided in the RAM 308 in order to set to wait for a period during which an image for informing the player that the jackpot is to be ended is displayed. Further, 6H is additionally stored as transmission information (command type) in the transmission information storage area described above in order to execute the general command end effect setting transmission process in the command setting transmission process (step S215).

  Further, in the special figure state update process which starts at the timing when the predetermined end production period ends (the timing when the production standby time management timer value changes from 1 to 0), the special figure state is set to inactive. . In the special figure state update process when the special figure is in a non-operating state, nothing is done and the process proceeds to the next step S214.

  In step S214, special drawing related lottery processing is performed. In this special drawing-related lottery process, the opening / closing control of the special drawing variable game and the variable winning opening 130 is not performed (the state of the special drawing is inactive), and the number of the special drawing variable games held is 1 In the case described above, the jackpot determination is first performed among various lotteries using the jackpot determination table, the high probability state transition determination table, the timer number determination table, and the like. Specifically, it is determined whether or not the special figure winning random number value stored in the random value storage area in step S203 is within the numerical range of the lottery data for the first special figure starting port in the jackpot determination table. When the random number value is within the numerical range of the lottery data for the first special figure start opening, information indicating that the special figure variable game is won and the jackpot flag storage area provided in the RAM 308 is a big hit is set. (Here, setting the jackpot information in the RAM 308 is referred to as setting the jackpot flag to ON). On the other hand, when the special figure winning random number value is outside the numerical range of the lottery data for the first special figure starting port, it is determined that the special figure variable game is out of the game, and the jackpot flag storage area provided in the RAM 308 is out of the storage area. (In this case, setting outlier information in the RAM 308 is setting the jackpot flag off). Note that the number of special figure variable games held is stored in the special figure hold number storage area provided in the RAM 308. Each time a hit determination is made, the number of special figure variable games held is determined. The value obtained by subtracting 1 is stored again in this special figure reservation number storage area. In addition, the random number value used for the hit determination is deleted.

  As a specific example, when the gaming state is a low probability state, and the special figure winning random number value acquired based on the detection of the ball winning to the first special figure starting port 126 is 10100, the jackpot flag is set to ON, When the special figure winning random number is 10200, the jackpot flag is set to OFF. In addition, when the special figure winning random number acquired based on the detection of the ball winning at the second special figure starting port 128 is 20100, the jackpot flag is set to ON, and when the special figure winning random number is 20200, the jackpot flag is set. Set to off.

  If the jackpot flag is set to ON, then the probability variation transition determination is performed. Specifically, it is determined whether or not the special figure random value stored in the random value storage area in step S209 is within the numerical range of the transition determination random number, and when the special figure random value is within the numerical range of the lottery data. Sets information indicating the start of a special jackpot game in the storage area of the probability variation (probability variation) flag provided in the RAM 308. (Here, setting the special jackpot game start information in the RAM 308 is referred to as turning on the probability variation flag). On the other hand, if the special figure random number value is outside the numerical range of the lottery data, information indicating that the jackpot game is started is set in the storage area of the probability variation flag (here, the information on the start of the jackpot game is Setting in the RAM 308 is referred to as setting the probability variation flag off). For example, when the acquired special figure random number value is 20, the probability variation flag is set to OFF. On the other hand, when the acquired special figure random value is 80, the probability variation flag is set to ON.

  Regardless of the result of the jackpot determination, the process for determining the timer number is performed next. Specifically, the value of the random counter for generating the special figure timer random value described above is acquired as the special figure timer random value. A timer number corresponding to the value of the jackpot flag and the timer random number range including the acquired special figure timer random number value is selected and stored in a predetermined timer number storage area provided in the RAM 308. Further, the fluctuation time corresponding to the timer number is stored as the special figure fluctuation display time in the special figure display symbol update timer, and the general command rotation start setting transmission process is executed in the command setting transmission process (step S215). For this purpose, 1H is additionally stored as transmission information (command type) in the transmission information storage area described above, and the process ends.

  For example, when the jackpot flag is off and the acquired special figure timer random number value is 50000, the special figure timer random number value is in the range of 0 to 60235, and therefore 1 corresponding to those conditions of the timer number determination table. The timer 1 indicating the timer number stored in the line and 5 indicating the variation time are selected and stored in the respective storage areas provided in the RAM 308. On the other hand, when the jackpot flag is on and the acquired special figure timer random number value is 64000, the special figure timer random number value is not in the range of 0 to 15535, so the timer 2 is not selected and is not 15536 to 24535. Timer 3 is not selected, and timer 4 is not selected because it is not 24536 to 62535. However, since it is within the range of 62536 to 65535, it is stored in the eighth line corresponding to those conditions in the timer number determination table. The timer 5 indicating the timer number and the variable time 50 are selected and stored in the respective storage areas provided in the RAM 308. In consideration of 2 ms which is the start cycle of the interrupt processing, a value obtained by multiplying the selected variation time value by 500 (1000 ms / 2 ms) is set in the variation time storage area. For example, when the variation time is 5 seconds, a value of 2500 is set as an initial value in the variation time storage area, and the value of the variation time storage area is set to 1 each time the timer update process in step S207 is executed. By subtracting, the passage of time can be measured by the number of execution times of interrupt processing. Further, when the value of the variable time storage area is subtracted every time (for example, five times) the timer interrupt process is executed (for example, 2 ms cycle), if the variable time is 10 seconds, 10 seconds is required. Since it is 10000 ms, dividing by the period (2 ms × 5) sets 1000 to the variable time storage area.

  In step S215, command setting transmission processing is performed (details will be described later). The output schedule information transmitted to the sub-control unit 400 is composed of 16 bits, bit 15 is strobe information (indicating that data is set when ON), bits 11 to 14 are command types ( 0H is a basic command, 1H is a symbol change start command, 4H is a symbol change stop command, 5H is a winning effect start command, 6H is an end effect start command, and 7H is a jackpot round Designated command, information for specifying the type of command such as a power recovery command for EH and a RAM clear command for FH, and bits 0 to 10 are command data (predetermined information corresponding to the command type). It is composed.

  Specifically, the strobe information is turned on and off in the command transmission process described above. If the command type is a symbol variation start command, the command data includes information indicating the value of the jackpot flag, the probability variation flag, the timer number selected in the special symbol related lottery process, etc. If it is a case, it includes the value of the jackpot flag, the probability variation flag, etc. If it is a winning effect command and an end effect start command, it includes the value of the probability variation flag, etc. If it is a jackpot round number designation command The value of the probability variation flag, the number of jackpot rounds, etc. are included. When the command type indicates a basic command, device information in the command data, presence / absence of winning at the first special figure starting port 126, presence / absence of winning at the second special figure starting port 128, winning of the variable winning port 130 Includes presence or absence.

  In the general command rotation start setting transmission process described above, the command type is 1H, the jackpot flag value stored in the RAM 308 as the command data, the probability variation flag value, the timer number selected in the special drawing related lottery process, the pending Information indicating the number of special figure variable games being set is set. In the general command rotation stop setting transmission process described above, 4H is set as the command type, and information indicating the value of the jackpot flag, the value of the probability variation flag, etc. stored in the RAM 308 is set as the command data. In the above-described general command winning effect setting transmission process, the effect control information to be output to the decorative symbol display device 110, various lamps 420, and the speaker 416 during the winning effect period stored in the RAM 308 as command type and 5H, Information indicating the value of the flag, the number of special figure variable games that are held, and the like are set. In the above-described general command end effect setting transmission process, the effect control information to be output to the decorative symbol display device 110, various lamps 420, and the speaker 416 during the effect standby period stored in the RAM 308 as command type 6H and command data, Information indicating the value of the flag, the number of special figure variable games that are held, and the like are set. In the general command big prize opening release setting transmission process described above, information indicating the command type 7H, the number of jackpot rounds stored in the RAM 308 as the command data, the value of the probability variation flag, the number of the special figure variation games held, etc. Set. In the above-described general command big prize closing setting transmission process, information indicating 8H as the command type, the number of big hits stored in the RAM 308 as the command data, the value of the probability change flag, the number of the special figure variable games held, etc. Set. In the sub-control unit 400, it is possible to determine the effect control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and the command data included in the output schedule information Based on this information, the contents of the effect control can be determined.

  In step S216, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 652 that is separate from the pachinko machine 100 via the information output circuit 334.

  In step S217, device monitoring processing is performed. In this device monitoring process, the signal states of various sensors stored in the signal state storage area in step 203 are read to monitor whether there is a glass frame opening error, a front frame opening error, or a lower pan full error. When a glass frame open error, front frame open error, or lower pan full error is detected, the transmission information to be transmitted to the sub-control unit 400 includes a glass frame open error, a front frame open error, a lower pan Set device information that indicates whether a full error has occurred. In addition, the solenoids 330 are driven to control the opening and closing of the second special figure starting port 128 and the variable prize opening 130, and the general diagram display device 112 and the special figure display device 114 are provided via the display circuits 322, 324, and 328. The display data to be output to the various status display units 326 and the like is set in the output port of the I / O 310. Further, the winning acceptance information set in the winning acceptance process (step S209) is output to the sub-control unit 400 via the output port 310.

  In step S218, it is monitored whether or not the low voltage signal is on. Then, when the low voltage signal is on (when power supply cutoff is detected), the process proceeds to step S220. When the low voltage signal is off (when power supply cutoff is not detected), the process proceeds to step S219.

  In step S219, timer interrupt end processing is performed. In this timer interrupt end process, the value of each register temporarily saved in step S201 is set in each original register, or interrupt permission is set.

  In step S220, a power interruption process for returning to the power interruption state upon power recovery is performed. Hereinafter, this power interruption process will be described in detail.

<Processing during power interruption>

A command for operating the means 250) is stored in a liquid crystal command storage area provided in the RAM 408, etc. Prepare to control the movable body. Further, when a predetermined condition is satisfied, a lottery such as whether or not to execute a predetermined effect, for example, whether or not to perform an effect using a chance button, is performed.

  In step S306, a decorative symbol display device control process is performed. In this decorative symbol display device control process, a command is output to the decorative symbol display control unit 500 via the output port of the I / O 410. Here, the display data to be output to the decorative symbol display control unit 500 included in the decorative symbol display control information prepared in step S305 is set in the output port of the I / O 410, and the display control of the decorative symbol display device 110 is performed. The decorative symbol display control unit 500 is caused to perform this.

  Sub-control unit 400 repeatedly executes the processes of steps S302 to S304 thereafter, except for interruption by strobe processing, chance button processing, or sub-control unit timer interrupt processing described later.

<Command input processing>
Next, the command input process (step S302) in the sub control unit main process will be described with reference to FIG. This figure is a flowchart showing the flow of command input processing.

  The RAM 408 mounted on the basic circuit 402 in the sub-control unit 400 shown in FIG. 5 is provided with a command storage area. In step S215 in the main control unit timer interrupt process shown in FIG. 8, the sub control unit 400 performs various commands transmitted from the main control unit 300 to the sub control unit 400 by performing a strobe interrupt process to be described later. Stored as an unprocessed command in the command storage area. The command storage area stores a symbol variation start command, a symbol variation stop command, a RAM clear command, and a power recovery command prepared in step S106 shown in FIG. In step S401 shown in FIG. 10B, the contents of the command storage area provided in the RAM 408 are confirmed, and it is determined whether or not an unprocessed command remains. If an unprocessed command remains in the command storage area, the process proceeds to step S402. If an unprocessed command does not remain in the command storage area, the process ends and returns to the sub-control unit main process. .

  In step S402, the process jumps to a process corresponding to the unprocessed command whose existence was affirmed in step S401. Hereinafter, some of the processes corresponding to the unprocessed commands will be described in detail.

  FIG. 10C is a flowchart showing the flow of the variation pattern selection process, and FIG. 10D is a flowchart showing the flow of the symbol stop process. The variation pattern selection process shown in FIG. 10C is executed when the symbol variation start command is an unprocessed command. Also, the symbol stop process shown in FIG. 4D is executed when the symbol variation stop command is an unprocessed command. Furthermore, there are other processes based on unprocessed commands. For example, a round start command that is output from the main control unit 300 every time the opening control of the variable winning opening 130 is started during the jackpot and includes information indicating the number of opening of the variable winning opening 130 after the jackpot start is an unprocessed command. For example, a round start process is performed. Other processing is omitted here.

  In step S501 of the variation pattern selection process shown in FIG. 10C, the jackpot flag value, the probability variation flag value, and the timer number included in the symbol variation start command which is an unprocessed command are extracted, and the RAM 408 is extracted. Are stored in the respective storage areas. In addition, after referring to the variation number selection table or the symbol determination table, effect data (in this embodiment, variation number, temporary stop symbol / stop symbol combination, etc.) is selected and stored in the storage area provided in the RAM 408. The process is terminated.

  Further, in step S601 of the symbol stop process shown in FIG. 10D, three decorative symbols constituting a combination of stop symbols stored in the symbol storage area prepared in the RAM 408 are displayed on the left of the decorative symbol display device 110. In the middle, the setting is made to display in the three display areas of the right symbol display areas 110a to 110c, and the process is terminated.

  In the round start process, information indicating the number of times the variable winning opening 130 is opened after the jackpot start included in the unprocessed command is extracted and stored in the storage area of the RAM 408.

<Strobe interrupt processing>
Next, the strobe interrupt process of the sub control unit 400 will be described with reference to FIG. This figure is a flowchart showing the flow of strobe interrupt processing.

  This strobe interrupt process is a process executed when the sub control unit 400 detects a strobe signal output from the main control unit 300. That is, as described above, the strobe signal is included as strobe information in the command transmitted to the sub-control unit 400. In the command setting transmission process (step S215) of the main control unit timer interrupt process shown in FIG. When a command is transmitted from the control unit 300 to the sub-control unit 400 and the sub-control unit 400 detects a strobe signal in the transmitted command, this strobe interrupt process is executed. In step S701 of the strobe interrupt process, the command output from the main control unit 300 is stored as an unprocessed command in the command storage area provided in the RAM 408.

<Chance button interrupt processing>
Next, the chance button interrupt process of the sub-control unit 400 will be described with reference to FIG. This figure is a flowchart showing the flow of chance button interrupt processing.

  This chance button interruption process is a process executed when the sub control unit 400 detects an operation of the chance button 146 by the chance button detection circuit 364.

  In step S801 of the chance button interrupt process, a value is acquired from the detection counter stored in the detection counter storage area of the RAM 408 for measuring the number of times the chance button 146 is pressed, and 1 is added to the acquired value. Store in the original detection counter storage area.

<Sub-control unit timer interrupt processing>
Next, the sub control unit variable update interrupt process executed by the CPU 404 of the sub control unit 400 will be described with reference to FIG. This figure is a flowchart showing the flow of the sub-control unit variable update interrupt process.

  The sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and this sub-control unit timer interrupt processing is performed at a predetermined cycle. Run with.

  In step S901 of the sub-control unit variable update interrupt process, 1 is added to the value of the timer variable storage area of the RAM 408 described in step S304 in the sub-control unit main process shown in FIG. Store in the area. Therefore, in step S304, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  Next, a pachinko machine (game table) according to Embodiment 2 of the present invention will be described. In the following description of the second embodiment, the same reference numerals as those used so far are used for the constituent elements having the same names as the constituent elements described so far. Further, the description overlapping with the description so far will be omitted, and only the initialization process in the main process of the main control unit, which is a feature of the pachinko machine according to the second embodiment, will be described.

  FIG. 11 is a flowchart illustrating the flow of the initialization process in the main process of the main control unit of the pachinko machine according to the second embodiment.

  The initialization process shown in FIG. 11 includes each process from step S1171 to step S1177. These processes, except for step S1177, are performed in the initialization process shown in FIG. 7 (steps S1071 to S1071). This is the same as step S1076). That is, in the initialization process shown in FIG. 11 as well, in the same way as the various setting processes in step S1071 shown in FIG. A predetermined initial value (for example, 0) is set in a random number counter storage area for generation. As described above, when an initial value is set in the random number counter storage area, it becomes easy for an unauthorized person to illegally obtain a random number value. However, in the second embodiment, the initial value is updated in step S1177. In other words, the value set in the random number counter storage area for generating the value of the normal winning random number, which is one of the software random numbers, and the random number for generating the value of the special figure random number, which is another software random number Both the value set in the counter storage area is updated until the content value of the acquired address becomes zero. For example, each time step S1171 is executed, 1 is added to the value set in the random number counter storage area for the normal winning, and 2 is set to the value set in the random counter storage area for the special drawing. Is added. By doing this, not only the timing of the random number value update (step S204 shown in FIG. 8) is shifted, but also in the first main controller timer interrupt process executed after the power is turned on and the initialization process shown in FIG. 7 is performed. The value acquired from the random number counter storage area in step S205 becomes a random value instead of a predetermined value such as an initial value, and it becomes extremely difficult for an unauthorized person to acquire a software random number value. The CPU 306 of the main control unit 300 that executes step S1171 corresponds to an example of the initial value update processing unit according to the present invention.

  In the description so far, the counter circuit 316 (see FIG. 5) used as a hardware random number counter is used for the special figure winning random number which is a random number for special figure winning (for jackpot determination). If the software random number is used, the technical idea of the second embodiment can be applied to this special figure winning random number.

  As described above, the embodiment in which the present invention is applied to a pachinko machine (bullet ball game machine) has been described in detail. However, the gaming table of the present invention is not limited to this, and for example, a medal or a game ball (pachinko ball) The present invention can also be applied to a spinning machine (slot machine) using. Further, the present invention may be applied to an arrange ball game machine, a ball ball game machine, and a pinball machine. In addition, the present invention is a gaming machine (for example, a casino machine, a video game machine, an encapsulated pachinko gaming machine) that can be played when the gaming medium is inserted, and a gaming machine that uses the gaming medium itself for the game (for example, It may be applied to a medal dropping game machine). Here, “inserting a game medium” means “betting”, and “bet” is also agreed. “Input of game media” includes “input of currency” and “input of electronic money”.
