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 balls from the storage tray 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).

<Basic circuit of main control unit>
Next, the basic circuit 302 of the main control unit 300 will be described in detail with reference to FIG. This figure shows the internal configuration of the basic circuit.

  The basic circuit 302 includes the above-described CPU 304, ROM (built-in ROM) 306, RAM (built-in RAM) 308, counter timer (timer circuit, counter circuit) 312, counter circuit (random number circuit) 316, I / O (external bus interface, In addition to a parallel input port, a serial communication circuit, and an address decoding circuit) 310 and WDT 313, a clock circuit 340, a verification block 342, and the like are provided.

  The clock circuit 340 divides the external clock EX (24 MHz clock in this example) input from the crystal oscillator 314b via the EX terminal by a predetermined frequency division ratio (1/2 in this example). In this circuit, the divided system clock SCLK (in this example, a 12 MHz clock) is supplied to the CPU core and internal circuits. The verification block 342 is a block that is connected to an external verification machine to perform chip verification (check for authenticity of the chip). Although the details will be described later, the random number circuit 316 counts the count value based on the random number clock RCK (in this example, a 10 MHz clock) input from the above-described crystal oscillator 314a via the RCK terminal, and the random number value It is a circuit for generating.

  Although not shown, the length of the wiring pattern connecting the clock circuit 340 and the crystal oscillator 314b is shorter than the length of the wiring pattern connecting the random number circuit 316 and the crystal oscillator 314a. The length of the wiring pattern connecting the basic circuit 302 and the crystal oscillator 314b may be shorter than the length of the wiring pattern connecting the basic circuit 302 and the crystal oscillator 314a. In this embodiment, the frequency of the random number clock RCK is less than the frequency of the system clock SCLK (in this example, 12 MHz), and is set in the counter / timer 312 as a period of main control unit timer interrupt processing to be described later. The frequency is set to a period (2 ms in this example) or more.

<Random number circuit>
Next, the random number circuit (counter circuit) 316 included in the basic circuit 302 will be described in detail with reference to FIGS. 7 is an internal configuration diagram of the random number circuit, and FIG. 8 is an internal configuration diagram of a frequency monitoring circuit included in the random number circuit.

  The random number circuit 316 includes two random number circuits, a random number circuit chA and a random number circuit chB. Since the internal configuration of the random number circuit chB is the same as that of the random number circuit chA, the illustration is omitted.

  The random number circuits chA and chB include a random number latch selection register for selecting either a random value fetch based on an external signal input or a random number fetch based on software, and a random value fetch based on software Random value fetch registers for fetching random values, random number registers 1 to 8 for storing the fetched random values (only random number registers 1 to 4 are shown in FIG. 7), random A random number latch flag register for indicating that a random number value is taken into the numerical registers 1 to 8, a random number interrupt control register for controlling a random number interrupt, a random number sequence change register for changing a random number sequence, and a random number And an internal information register for storing a clock signal state indicating whether or not the clock RCK is abnormal.

  The random number circuit 316 can generate two types of 16-bit random numbers having different random number sequences for each channel, and use random number setting, random number initial setting, random number collection provided in a predetermined area of the ROM 306. By changing the contents of the setting, the use / nonuse of the random number circuits chA and chB, the selection of the initial value / random number sequence changing method, the update cycle of the random value, the method of acquiring the random value, the interrupt condition, etc. are changed. It is possible. In this embodiment, the P0 terminal is a special figure 1 start opening detection signal that is output when a ball enters the first special figure start opening 126, and the P1 terminal has a ball entering the second special figure start opening 128. The special figure 2 entrance opening detection signal that is output when there is, and the P2 terminal is input with the general start entrance detection signal that is output when there is an entrance at the ordinary start opening 124. Is connected to the sensor circuit 320, but is not limited thereto.

  The random number circuits chA and chB include a frequency monitoring circuit 316a. As shown in an enlarged view in FIG. 8, the frequency monitoring circuit 316a receives a smoothing circuit to which the system clock SCLK output from the clock circuit 340 is input, and is input from the crystal oscillator 314a through the RCK terminal. The smoothing circuit to which the random number clock RCK is input is compared with the frequency of the smoothed system clock SCLK and the frequency of the random number clock RCK, and the frequency of RCK is equal to or lower than the frequency of the system clock SCLK (RCK = <SCLK). A comparator that determines that the frequency of the random number clock RCK has become abnormal and sets the clock signal status bit of the internal information register to 1.

  The CPU 304 of the main control unit 300 refers to the clock signal status bit of the internal information register at a predetermined timing. When the clock signal status bit of the internal information register is set to 1 (when the frequency of the random number clock RCK is equal to or lower than the frequency of the system clock SCLK (RCK = <SCLK)), the random number clock RCK When it is determined that some abnormality (for example, disconnection of the wiring pattern connecting the random number circuit 316 and the crystal oscillator 314a) has occurred, and the clock signal status bit of the internal information register is set to 0 (the frequency of the random number clock RCK) Is larger than the frequency of the system clock SCLK (when RCK> SCLK), it is determined that the random number clock RCK is normal.

  In this embodiment, when the frequency of the random number clock RCK is equal to or lower than the frequency of the system clock SCLK (RCK = <SCLK), it is determined that the random number clock RCK is abnormal. However, the present invention is not limited to this. Alternatively, for example, a plurality of types of threshold values for determining an abnormality may be provided, and one threshold value may be selected from the plurality of types of threshold values. Further, the frequency of the system clock SCLK and the frequency of the random number clock RCK are not limited to the numerical values shown in the present embodiment. For example, an abnormality determination method such as RCK = <2 × SCLK, RCK = <1/2 × SCLK, or the like may be set based on predetermined information (for example, information stored in the ROM). Ideally, it is desirable to make an abnormality when the 10 MHz random number clock RCK has a frequency of 3 MHz or less (1/4 or less of the system clock) with respect to the 12 MHz system clock SCLK.

<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 processing in accordance with a control program stored in advance in the ROM 306.

  In step S101, initial setting 1 is performed. In this initial setting 1, the stack initial value is set in the stack pointer (SP) of the CPU 304, the interrupt mask is set, the initial setting of the I / O port 310, the initial setting of various variables stored in the RAM 308, and the operation permission to the WDT 313 is permitted. 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.

  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 S105, it is determined whether or not to return to the state before the power interruption (before the power interruption), and the state before the power interruption is not restored (when the basic circuit 302 of the main control unit 300 is set to the initial state). ) Proceeds to step S107. Similarly, when the power status information indicates information other than “suspend (information indicating that power interruption processing has been performed)”, the process proceeds to step S108.

  Specifically, first, a RAM clear signal transmitted when a store clerk or the like of the game shop operates the operation unit provided on the power supply board is turned on (indicating that there is an operation), that is, It is determined whether or not RAM clear is necessary, and if the RAM clear signal is on (RAM clear is necessary), the process proceeds to step S107 to set the basic circuit 302 to the initial state. On the other hand, when the RAM clear signal is OFF (when the RAM clear is not necessary), the power status information stored in the power status storage area provided in the RAM 308 is read, and whether the power status information is information indicating suspend. Determine whether or not. If the power status information is not information indicating suspend, the process proceeds to step S107 to set the basic circuit 302 to the initial state. If the power status information is information indicating suspend, a predetermined area of the RAM 308 is set. A checksum is calculated by adding all the 1-byte data stored in (for example, all areas) to a 1-byte register whose initial value is 0, and the calculated checksum results in a specific value (for example, 0) (whether or not the checksum result is normal). If the checksum result is a specific value (for example, 0) (if the checksum result is normal), the process proceeds to step S106 to return to the state before power interruption, and the checksum result is a specific value. If the value is other than 0 (for example, 0) (if the checksum result is abnormal), the process proceeds to step S107 in order to set the pachinko machine 100 to the initial state. Similarly, if the power status information indicates information other than “suspend”, the process proceeds to step S107.

  In step S106, power recovery processing is performed. In this power recovery process, the stack pointer stored in the stack pointer save area provided in the RAM 308 at the time of power failure is read and reset to the stack pointer. 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 step S107, initialization processing is performed. In this initialization processing, interrupt prohibition setting, stack initial value setting to the stack pointer, initialization of all storage areas of the RAM 308, and the like are performed.

  In step S108, the basic random number update process is performed after setting the interrupt inhibition. In this basic random number update process, two random number counters for generating a normal figure timer random value and a special figure timer random value 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. The other random number counters are similarly updated. Further, after this basic random number update process is completed, 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.

<Main controller timer interrupt processing>
Next, main control unit timer interrupt 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 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, an open sensor for detecting whether the above-described glass frame 154 is in an open state or a closed state via the input port of the I / O 310, the above-described lower plate 150 is provided. A detection signal of various sensors 318 including a bottom plate full sensor for detecting whether or not the ball is full and a plurality of ball detection sensors is input to monitor the presence or absence of the detection signal. The signal state is stored in a signal state storage area. In this embodiment, information on the presence or absence of the detection signal of each sphere detection sensor detected in the timer interruption process of the last time (about 4 ms before) is stored in the RAM 308 for each previous sphere detection sensor. This information is read from the area, and this information is stored in the RAM 308 in the detection signal storage area provided in advance for each sphere detection sensor, and the detection of each sphere detection sensor detected by the previous timer interruption process (about 2 ms before). Information on the presence or absence of a signal is read from the current detection signal storage area provided in the RAM 308 for each sphere detection sensor, and this information is stored in the previous detection 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 S204 and step S205, jackpot type random number update processing and basic random number update processing are performed. In these jackpot type random number update processing and basic random number update processing, the jackpot type random number used in the main control unit 300 is updated next. The updating method is the same as that in steps S108 and S109 described above.

  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. In this timer update process, a normal symbol display symbol update timer for timing the time for the symbol to be changed / stopped on the normal symbol display device 112, and a time for 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, a timer for measuring a predetermined winning effect time, a predetermined opening time, a predetermined closing time, a predetermined end effect period, and the like 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. Note that even if the random number clock RCK is abnormal, there is no reason to limit the increase in the number of prize balls paid out for winning. Therefore, even when the random number clock RCK is abnormal as in step 209 described later, special processing is performed. However, a predetermined process such as not adding the number of prize balls may be performed when there is an abnormality in the random number clock RCK in a punitive sense for an unauthorized person. In the next step S209, a winning acceptance process is performed (details will be described later).
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 (when ON, indicates that this is the first command transmission after power-on), bits 4-5 indicate the current processing type (0-3), and bits 0-3 indicate the number of payout requests after processing I am doing so.

  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 (a general-purpose general-purpose timer value to be described later is 1 or more), on / off drive control for repeatedly turning on and off the 7-segment LED constituting the general map display device 112 is performed. Do.

  Also, in the normal 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), if the hit flag is on, When the 7-segment LED constituting the general-purpose display device 112 is turned on / off so as to be in the first mode, and the hit flag is off, the normal diagram is displayed as in the above-described normal mode. The 7-segment LED constituting the device 112 is controlled to be turned on / off, and then stored in a routine stop time management timer provided in the RAM 308 to maintain the display for a predetermined stop display period (for example, 500 msec). Information indicating the stop period is set in the area. 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 the 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 managed. 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, 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 inactive), and the general map variable game that is on hold 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 (details will be described later). 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.

  If the jackpot flag is set to ON, then the probability variation transition determination is performed. Specifically, it is determined whether or not the jackpot type random number is in the numerical range of the transition determination random number, and if the special figure random number value is in the numerical range of the lottery data, the probability variation (probability variation) provided in the RAM 308 is determined. ) Information indicating that a special jackpot game is started is set in the flag storage area. (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, when the jackpot type random number 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 set). Setting in the RAM 308 is referred to as setting the probability variation flag off).

  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 reason, 01H is additionally stored as transmission information (general information) in the transmission information storage area described above, and the process ends.

  In step S215, command setting transmission processing is performed. The output schedule information (command) transmitted to the sub-control unit 400 and the payout control unit 550 is composed of 16 bits, and bit 15 is strobe information (indicating that data is set when ON), Bits 11 to 14 are command types (basic command for 00H, symbol change start command for 01H, symbol change stop command for 04H, winning effect start command for 05H, and end effect start command for 06H. , 07H is a jackpot round number designation command, 0EH is a power recovery command, 0FH is a RAM clear command, 10H is a random clock error command, etc. Bits 0 to 10 are composed of command data (predetermined information corresponding to the command type).

  Specifically, the strobe information is turned on and off by command transmission processing. 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 01H, 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, 04H 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 the command type and 05H as command type 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 end effect setting transmission process described above, 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 the command type is stored in the command type 06H. 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 transmission process described above, the information indicating the command type is 07H, the number of big hits stored in the RAM 308 as the command data, the value of the probability variation flag, the number of the special figure variable games held, etc. Set. In the above-described general command big prize closing setting transmission process, the information indicating the command type is 08H, 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 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 the various sensors stored in the signal state storage area in step 203 are read out to monitor whether there is a glass frame opening error or a lower pan full error, and so on. When a full tank error is detected, device information indicating whether or not there is a glass frame opening error or a lower pan full error is set in the transmission information to be transmitted to the sub-control unit 400. 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 output schedule information set in the payout request number transmission process (step S210) 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, the voltage monitoring circuit that monitors the voltage value of the power supplied from the power management unit 650 to the main control unit 300 outputs a voltage drop signal indicating that the voltage has dropped when it is equal to or lower than a predetermined value. Whether or not a power-off is detected. If a power-off is detected, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is displayed. The return data is saved in a predetermined area of the RAM 308, and power interruption processing such as initialization of the input / output port is performed. In addition, the power status is set to “suspend”.

<Prize acceptance process>
Next, the winning acceptance process in the main control unit timer interrupt process described above will be described with reference to FIG. This figure is a flowchart showing the flow of the winning acceptance process.

  In step S301 to step S303, the first special figure start port detection signal storage area, the previous first special figure start port detection signal storage area, and the current first first special figure start port detection signal storage area are stored in the respective storage areas. The information on the presence / absence of the detection signal of the first special figure starting mouth ball detection sensor is compared, and the information on the presence / absence of the detection signals for the past three times in the first special figure starting mouth ball detection sensor matches the predetermined winning pattern information. It is determined whether or not. In the first special figure starting mouth ball detection sensor, information on the presence or absence of detection signals for the past three times is predetermined winning determination pattern information (in the present embodiment, the first special figure starting mouth detection signal is turned on previously, When the first special figure start port detection signal is on and the first special figure start port detection signal is coincident with the information indicating that the first special figure start port detection signal is off the previous time), it is determined that there is a ball entering the first special figure start port 126 To do. For example, if the information on the presence or absence of detection signals for the past three times matches the above-described winning determination pattern information in the first special figure starting opening ball detection sensor, the first special figure starting opening 126 has been entered. After determining and performing processing associated with entering the first special figure starting port 126 thereafter, if the information on the presence or absence of detection signals for the past three times does not match the above-described winning determination pattern information, The process is terminated without performing the process associated with entering the first special figure starting port 126.

  In step S304, it is determined whether there is an abnormality in the frequency of the random number clock by referring to the clock signal status bit of the internal information register. If there is an abnormality in the frequency of the random number clock, the process proceeds to step S306 without executing the process of step S305. If there is no abnormality in the frequency of the random number clock, the process proceeds to step S305.

  In step S305, a random number is acquired from the counter circuit (random number circuit) 316. More specifically, when there is a prize at the first special figure starting port 126 and the number of special figure variable games held is less than four, the counter corresponding to the first special figure starting port 126 is displayed. The value is acquired from the random value register of the circuit 316 as a special figure winning random value. 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 steps S306 to S308, the second special figure start port detection signal storage area, the previous second special figure start port detection signal storage area, and the current second special figure start port detection signal storage area are stored in the respective storage areas. The information on the presence / absence of the detection signal of the second special figure starting ball detecting sensor is compared, and the information on the presence / absence of the detection signals for the past three times in the second special figure starting ball detecting sensor coincides with the predetermined winning pattern information. It is determined whether or not. The information on the presence or absence of detection signals for the past three times in the second special figure starting mouth ball detection sensor is predetermined winning determination pattern information (in this embodiment, the second special figure starting mouth detection signal is turned on previously, When the second special figure start port detection signal coincides with the information indicating that the second special figure start port detection signal is off the second time, the determination is made that the second special figure start port 130 has entered the ball. To do. For example, when the information on the presence / absence of detection signals for the past three times matches the above-described winning determination pattern information in the second special figure start opening ball detection sensor, there is a ball entering the second special figure start opening 128. After determining and performing processing associated with entering the second special figure starting port 128 thereafter, if the information on the presence / absence of detection signals for the past three times does not match the above-described winning determination pattern information, The process is terminated without performing the process associated with entering the second special figure starting port 128.

  In step S309, it is determined whether or not there is an abnormality in the frequency of the random number clock by referring to the clock signal status bit of the internal information register. If there is an abnormality in the frequency of the random number clock, the process proceeds to step S311 without executing the process of step S310. If there is no abnormality in the frequency of the random number clock, the process proceeds to step S310.

  In step S310, a random number is acquired from the counter circuit (random number circuit) 316. More specifically, if there is a prize at the second special figure starting port 128 and the number of special figure variable games held is less than four, the counter corresponding to the second special figure starting port 128 The value is acquired from the random value register of the circuit 316 as a special figure winning random value. 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 steps S311 to S313, the general-purpose start-up ball detection stored in the storage areas of the previous-time general-purpose start-port detection signal storage area, the previous-time general-purpose start-port detection signal storage area, and the current-time general-purpose start-port detection signal storage area. The information on the presence / absence of the detection signal of the sensor is compared, and it is determined whether or not the information on the presence / absence of the detection signal for the past three times in the normal start ball detection sensor matches the predetermined winning pattern information. The information on the presence / absence of detection signals for the past three times in the general-purpose start-mouth detection sensor is pre-determined winning determination pattern information (in this embodiment, the current general-purpose start-point detection signal is on, If the detection signal matches the information indicating that the normal start detection signal is OFF the second time, it is determined that the ball has passed through the normal start opening 124. For example, when the information on the presence / absence of the detection signals for the past three times matches the above-described winning determination pattern information in the normal-use start-up ball detection sensor, it is determined that the ball of the normal-use start opening 124 has passed, and thereafter When the information on the presence / absence of the detection signals for the past three times does not match the above-described winning determination pattern information, the subsequent general figure start port 124 is processed. The process is terminated without performing the process associated with the passage of the ball.

  In step S314, it is determined whether or not there is an abnormality in the frequency of the random number clock by referring to the clock signal status bit of the internal information register. If there is an abnormality in the frequency of the random number clock, the process ends without executing the process of step S315. If there is no abnormality in the frequency of the random number clock, the process proceeds to step S315.

  In step S315, a random number is acquired from the counter circuit (random number circuit) 316. More specifically, when there is a winning at the general-purpose start opening 124 and the number of the general-purpose variable games held is less than two, the counter circuit 316 corresponding to the general-purpose start opening 124 is disturbed. The value is acquired from the numeric register as a random number value for normal winning. Further, a value is acquired from the above-described random number counter for generating a normal random number value as a normal random number value, and stored in a random value storage area provided in the RAM 308 together with the normal winning random number value.

  In this embodiment, the CPU 304 does not disturb the counter circuit 316 unless the input to various start port detection signals is turned on → on and a period of at least one interrupt cycle (2 ms in this embodiment) has passed. The numeric register value is not latched. On the other hand, in the random value register, the latch signal when various start port detection signals are input does not latch unless an on-level signal corresponding to four cycles of the random number clock RCK is passed. In this embodiment, since the random number clock RCK is 10 MHz, the latching is completed when the maximum is less than 0.4 μs + 0.1 μs = 0.5 μs. That is, the latch by the various start port detection signals is surely ended before the value is acquired from the random value register in step S305 or the like.

<Special status update process>
Next, the special figure state update process in the main controller timer interrupt process described above will be described with reference to FIG. This figure is a flowchart showing the flow of special figure state update processing.

  In step S401, it is determined whether or not there is an abnormality in the frequency of the random number clock by referring to the clock signal status bit of the internal information register. If there is an abnormality in the frequency of the random number clock, the process proceeds to step S410 without executing the processing of steps S402 to S409. If there is no abnormality in the frequency of the random number clock, the process proceeds to step S402.

  In step S402, it is determined whether or not the special figure is changing. If applicable, the process proceeds to step S403, and if not, the process proceeds to step S406. In step S403, it is determined whether or not the 7-segment LED constituting the special figure display device 112 was extinguished last time. If the previous segment was extinguished, the process proceeds to step S405 and the 7-segment LED is lit, and the previous one is lit. In this case, the process proceeds to step S404 and the 7-segment LED is turned off. As a result, lighting / extinguishing drive control for repeatedly turning on and off the 7-segment LED is performed.

  In step S406, it is determined whether or not it is a special figure fluctuation stop. If applicable, the process proceeds to step S407, and if not, the process ends.

  In step S407, the special figure is stopped and displayed according to the information of the jackpot flag. Specifically, when the jackpot flag is on and the probability change flag is off, the special figure display device 114 is displayed. When the above-described special figure 1 and jackpot flag is on and the probability variation flag is on, the special figure display device 114 is displayed. When the above-mentioned special figure 2 and jackpot flag are off, the 7-segment LED constituting the special figure display device 112 is controlled to be turned on / off so as to be in the above-described special figure 3 mode.

  In step 408, a stop display period is set. Specifically, information indicating the stop period is set in a storage area of a special figure stop time management timer provided in the RAM 308 in order to maintain the display of the special figure for a predetermined stop display period (for example, 500 milliseconds). 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 step S409, after setting the output of the stop command, the process ends. Specifically, 02H is additionally stored as transmission information (general information) in the above-described transmission information storage area in order to execute the general command rotation stop setting transmission process in the command setting transmission process (step S215 above).

  Although not shown, in the special figure state update process that starts at the timing when the predetermined stop display period ends (the timing when the special figure stop time management timer value changes from 1 to 0), the jackpot flag is on. In such a case, a special figure standby provided in the RAM 308 for waiting for a predetermined winning effect period (for example, 3 seconds), that is, a period during which an image for notifying the player that the jackpot by the decorative symbol display device 110 is started is displayed. Information indicating the winning effect period is set in the storage area of the time management timer. 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. 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, in the special figure state update processing which is repeated at predetermined timing (for example, 15 rounds) and this door member opening / closing control is repeated a predetermined number of times (for example, 15 rounds), a predetermined end effect period (for example, 3 seconds), that is, by the decorative symbol display device 110 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, 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 step S410, the jackpot flag is set to off (lost), and in step S411, the fluctuation of the special figure is stopped. In the next step S412, 10H is additionally stored as transmission information (general information) in the transmission information storage area in order to execute the stop setting transmission process due to the random number clock abnormality in the command setting transmission process (step S215). To finish the process. If there is an abnormality in the random number clock RCK, the special figure or / and usual figure display may be deleted.

<Payment control unit main process>
Next, the payout control unit main process executed by the payout control unit 550 will be described with reference to FIG. This figure is a flowchart showing the flow of the main process of the payout control unit.

  The payout control unit 400 is provided with a reset signal output circuit that outputs a reset signal when the power is turned on. The CPU of the payout control unit 400 to which this reset signal has been input starts resetting by a reset interrupt and executes processing according to a control program stored in advance in the ROM.

  In step S501, initial setting 1 is performed. In the initial setting 1, a stack initial value is set in the stack pointer (SP) of the CPU.

  In step S502, whether or not the low voltage signal is ON, that is, the voltage value of the power source supplied from the power management unit 650 to the payout control unit 550 by the voltage monitoring circuit is a predetermined value (9v in this embodiment). ), 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 power-off is detected), step S502 is repeated. If the low-voltage signal is off (when power-off is not detected), step S502 is performed. The process proceeds to S503.

  In step S503, initial setting 2 is performed. In this initial setting 2, processing for setting a numerical value for determining a cycle for executing a payout control unit timer interrupt processing, which will be described later, in the counter timer, setting for permitting writing to the RAM, initial setting of the I / O port Make settings.

  In step S504, it is determined whether or not the state before the power interruption (before power interruption) is restored. If the state before the power interruption is not restored (when the pachinko machine 100 is set to the initial state), step S506 is performed. If the process returns to the state before the power interruption, the process proceeds to step S505.

  Specifically, first, a RAM clear signal transmitted when a store clerk or the like of the game shop operates the operation unit provided on the power supply board is turned on (indicating that there is an operation), that is, It is determined whether or not the RAM clear is necessary. If the RAM clear signal is on (when the RAM clear is necessary), the process proceeds to step S506 in order to set the pachinko machine 100 to the initial state. On the other hand, when the RAM clear signal is OFF (when the RAM clear is not necessary), the power status information stored in the power status storage area provided in the RAM is read, and whether the power status information is information indicating suspend. Determine whether or not. If the power status information is not information indicating suspend, the process proceeds to step S506 to set the pachinko machine 100 to an initial state. If the power status information is information indicating suspend, a predetermined area of the RAM is stored. A checksum is calculated by adding all the 1-byte data stored in (for example, all areas) to a 1-byte register whose initial value is 0, and the calculated checksum results in a specific value (for example, 0) (whether or not the checksum result is normal). If the checksum result is 0 (if the checksum result is normal), the process proceeds to step S505 to return to the state before the power interruption. If the checksum result is other than 0 (checksum) If the result is abnormal), the process proceeds to step S506 to set the pachinko machine 100 to the initial state. Similarly, if the power status information indicates information other than “suspend”, the process proceeds to step S506.

  In step S505, power recovery processing is performed. In this power recovery process, initialization of the RAM storage area to be cleared upon power recovery (the command buffer for storing commands, the storage area excluding error status for storing error status, etc.) is initialized. And so on.

  In step S506, initialization processing is performed. In this initialization process, interrupt prohibition setting, stack initial value setting to the stack pointer, predetermined areas (for example, all storage areas) of the RAM, and the like are performed.

  In step S507, initial setting 3 is performed. In the initial setting 3, information other than the illegal payout error and the payout excess error among the error statuses stored in the error status storage area provided in the RAM is cleared, interrupt permission is set, and the like.

  In step S508, it is determined whether there is unanalyzed data in the data input from the main control unit 300. If there is unanalyzed data, command analysis processing is performed in step S509, and there is no unanalyzed data. Then, the process proceeds to step S510.

  In step S510, it is monitored whether or not the low voltage signal is off. If the low voltage signal is off (when power-off is not detected), the process returns to step S508, and the low voltage signal is on. In the case of detecting a power shutdown, the process proceeds to step S511.

  In step S511, a power interruption process is performed. In the power interruption process, the current stack pointer value is stored in the stack pointer save area provided in the RAM, and information indicating suspend is set in the power status storage area. Further, all 1-byte data stored in a predetermined area (for example, all areas) of the RAM is added to a 1-byte register whose initial value is 0 and stored in a checksum calculation numerical storage area. The value obtained by subtracting the result of addition from the value is calculated as a checksum (checksum at power interruption), and the calculated checksum at power interruption is stored in the above-mentioned numerical storage area for checksum calculation, and written to the RAM. Perform prohibited settings.

  In step S512, it is monitored whether or not the low voltage signal is on. When the low voltage signal is on (when power-off is detected), the process of step S512 is repeatedly executed to turn off the low voltage signal. When the low-voltage signal is off (when power-off is not detected), the process returns to step S501, and the payout control unit reset interrupt process is started from the beginning.

<Discharge control unit timer interrupt processing>
Next, a payout control unit timer interrupt process executed by the CPU of the payout control unit 550 will be described with reference to FIG. This figure is a flowchart showing the flow of the payout control unit timer interrupt process.

  The payout control unit 550 includes a counter / timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 1 ms). With this timer interrupt as a trigger, the payout control unit timer interrupt processing is performed at a predetermined cycle. Start.

  In step S601, 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 to the stack area is performed. In step S602, port input management processing is performed. In this port input management process, the value of the I / O port is acquired and the state of various sensors is detected.

  In step S603, timer update management processing is performed. In this timer update management process, various timers including timers for measuring the lighting / extinguishing time of the payout notification LED, motor driving / non-driving time, and the like are updated.

  In step S604, error management processing is performed. In this error management process, it is determined whether a random number clock abnormality command has been received from the main control unit 300, and if applicable, information indicating random number clock abnormality is stored in an error status storage area provided in the RAM. Also, a dish full signal input to the I / O port is detected to determine whether or not the dish full signal is on. When the dish full signal is on (when the lower plate 150 is full of balls) ) Stores information indicating the dish full error in the error status storage area provided in the RAM, and when the dish full signal is OFF (when there is a free space for storing balls in the lower plate 150), an error status is stored. Information indicating the release of the dish full error is stored in the storage area. Further, it is detected whether the communication line between the main control unit 300 and the payout control unit 550 is communicable due to disconnection or the like, and if communication is possible, it is possible to communicate with the error status storage area provided in the RAM. In addition, information indicating that communication is impossible is stored when communication is impossible. In the error management process, an error release switch signal input to the I / O port is detected to determine whether the error release signal is on. If the error release signal is on, an error status is stored. The information indicating the random number clock abnormality, the illegal payout error information, or the payout excess error information stored in the area is initialized, and these errors are canceled.

  Note that, regarding information indicating random clock anomaly, unlike other errors, the error may not be canceled even when an error cancellation switch signal is detected. Because, in the case of random clock anomaly, the special figure that is held when the error is restored is changed, and the reliability of the random number for the special figure lottery is very low. This is because there is a case where it is not desired to play a game. Also, “There are multiple abnormal states, the first type of abnormal state is provided so that the abnormal state can be canceled by an abnormal release input, and the second type of abnormal state is provided so that the abnormal state cannot be canceled by an abnormal release input. "The second type of abnormal state includes at least the abnormal state of the random number clock" can be applied to other control units and slot machines. In this case, “the second type of abnormal state may be stored in the second type of abnormal state by backup even when the power is turned off”, and further, “the second type of abnormal state is stored. "Can be released by initializing a plurality of stored information including the second type of abnormal state", and may further include "a plurality of stored information related to the interests of the player" Furthermore, “the information related to the player's profit may be information determined by lottery based on a random number generated based on a random number clock”. As a result, it is possible to reliably notify the abnormality of the random number clock, and when there is an abnormality in the random number clock, it is possible to reliably clear the profits drawn based on the random number clock. Can be prevented from suffering disadvantages.

  In step S605, CR unit communication management processing is performed. In this CR unit communication management process, it is determined whether or not information indicating random number clock abnormality is stored in the error status storage area described above, and if information indicating random number clock abnormality is stored, Avoid lending. Also, a signal for returning the card to the CR unit is not output. Specifically, the game media lending process is skipped, or the CR unit return process is skipped. On the other hand, if information indicating random clock anomaly is not stored, the game medium lending signal is received from the interface unit 556 to determine whether or not the game medium lending signal sensor signal is on, and the game medium lending signal is determined. Is turned on (when a ball lending request is input from the interface unit 556), information indicating that there is a game medium lending request is stored in the game medium lending information storage area provided in the RAM.

  In step S606, a payout management process is performed. In this payout management process, the information indicating the random number clock abnormality, the information on the illegal payout error, and the information on the payout excess error are read from the above-described error status storage area. The number of payouts is monitored based on a payout sensor signal (hereinafter, sometimes referred to as a payout sensor signal) input via the terminal. That is, when a predetermined error (one of the errors in this case) has occurred, the driving of the motor, that is, the payout of a prize medium (for example, a game ball) from the payout device is stopped.

  Also, from the error status storage area described above, information indicating random clock error, dish full error information, illegal payout error information, and payout excess error information are read, and if any error has not occurred, payout One of start monitoring processing, initial position search operation processing, normal payout operation processing, retry operation processing, and reverse rotation operation processing is performed.

  In the payout start monitoring process, when the number of lending requests and the number of requested prize balls are 0, and the number of requested next prize balls is other than 0, the number of requested next prize balls is set as the number of requested prize balls, and the next prize ball request Clear the number. If the position of the motor driving the sprocket is uncertain (when the operation mode is the initial position search operation mode), 1 is subtracted from the payout completion number check and stored in the payout completion number check storage area. When the position of the motor for driving is fixed (when the operation mode is the normal payout operation mode), 0 is set in the payout completion number check storage area as the payout completion number check. Also, the number of prize balls requested is converted into an amount for driving the motor of the sprocket (motor drive amount), which is stored in the motor drive amount storage area provided in the RAM, and the motor control data table provided in the RAM is referenced. Then, motor drive control data corresponding to the motor drive amount is selected, and motor drive control data indicating normal rotation is output to the motor control circuit via the I / O port. As a result, the motor control circuit changes the excitation position of the motor of the sprocket a predetermined number of times to rotate the sprocket in the forward direction.

  In the initial position search operation process and the normal payout operation process, after the motor has been driven, a payout completion check is read from the payout completion number check storage area, and when the payout completion check is 0, preparation for executing the payout start monitoring process is performed. If the payout completion check is other than 0, information indicating the payout device error is set in the error status storage area, and preparation for executing the retry operation process is performed.

  In the retry operation process, wait for a predetermined time to elapse (wait for the retry operation start wait timer to become 0), and when the retry operation start wait timer becomes 0, execute the reverse rotation operation process. Make preparations. In the reverse rotation operation process, motor drive control data corresponding to the motor drive amount is selected with reference to the motor control data table described above, and motor drive control data indicating reverse rotation is output to the motor control circuit via the I / O port. To do. As a result, the motor control circuit changes the excitation position of the motor of the sprocket a predetermined number of times to drive the sprocket in a reverse rotation. Further, in the reverse rotation operation process, preparation is made for executing the payout start monitoring process after the motor is driven.

  In step S607, motor drive management processing is performed. In the motor drive management process, any one of a drive start monitoring process, an acceleration drive process, a constant speed drive process, a brake drive process, and a drive end process is performed.

  In the drive start monitoring process, information indicating a random clock error, dish full error information, illegal payout error information, and payout excess error information are read from the error status storage area described above, and no error has occurred. In this case, motor drive control data corresponding to the motor drive amount is selected with reference to the motor control data table, and motor drive control data indicating normal rotation is output to the motor control circuit via the I / O port. As a result, the motor control circuit changes the excitation position of the motor of the sprocket a predetermined number of times to rotate the sprocket in the forward direction.

  In the acceleration drive processing and constant speed drive processing, 1 is subtracted from the payout completion number check every time the motor excitation position is changed 16 times, except when the sprocket is in the initial position search operation or reverse rotation operation. Store in the payout completion number check storage area. When the updated payout completion number check is less than −4, preparation for executing the brake drive process is made. Further, the game medium lending information is read from the above-mentioned game medium lending information storage area, the presence / absence of information indicating that there is a request for lending a game medium is determined, and information indicating that there is a request for lending a game medium is present. In some cases (when a ball lending request is input from the interface unit 556 during the payout of award balls), preparations for executing the brake driving process are made.

  In the brake drive process, it waits for a predetermined time to elapse (waits for the motor drive management timer to become 0), and when the motor drive management timer becomes 0, prepares to execute the drive end process In the drive end process, a post-process for driving the motor is performed.

  In step S608, LED management processing is performed. In this LED management process, when the information indicating the abnormality of the random number clock in the error status storage area indicates an abnormality, an LED for notifying the player that an abnormality has occurred in the frequency of the random number clock is provided. When the information indicating the abnormality of the random number clock in the error status storage area does not indicate abnormality, the LED is turned off. In addition, when the illegal payout error information in the error status storage area indicates that an illegal payout error is occurring, an LED for notifying the player that an illegal payout error has occurred is turned on. At the same time, if it indicates that an illegal payout error has not occurred, the LED is turned off. In addition, when the payout excess error information in the error status storage area indicates that a payout excess error is occurring, an LED for notifying the player that a payout excess error has occurred is turned on. At the same time, when it indicates that no payout excess error has occurred, the LED is turned off.

  In step S609, signal output management processing is performed. In this signal output management process, game information stored in the RAM (for example, a prize ball signal output each time a payout sensor signal is input) is separated from the pachinko machine 100 via an information output circuit (not shown). To the information input circuit (not shown).

  In step S610, timer interrupt end processing is performed. In this timer interrupt end process, the value of each register temporarily saved in step S601 is set in each original register, or interrupt permission is set.

<Strobe interrupt processing>
Next, strobe interrupt processing executed by the CPU of the payout control unit 550 will be described with reference to FIG. This figure is a flowchart showing the flow of strobe interrupt processing.

  The payout control unit 550 receives a strobe signal output from the main control unit 300. When the main control unit 300 transmits a command to the payout control unit 550, the strobe signal is input to the payout control unit 550. A strobe interrupt is notified to the CPU of the payout control unit 550.

  The CPU of the payout control unit 550 that has detected the strobe interrupt executes the strobe interrupt process, and stores the command received from the main control unit 300 in a predetermined storage area of the RAM in step S701.

<Sub control section main processing>
Next, the sub control unit main 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 main process of the sub control unit.

  The sub-control unit 400 is provided with a reset signal output circuit that outputs a reset signal when the power is turned on. The CPU 404 of the basic circuit 402 to which this reset signal has been input starts reset by a reset interrupt and executes processing in accordance with a control program stored in advance in the ROM 406. First, various initial settings are performed in step S801. In this initial setting, initial setting of input / output ports, initialization of various variables, and the like are performed. In step S802, command input processing (details will be described later) is performed.

  In step S803, a command is output to the sub-control unit 500 via the output port of the I / O 410. In step S804, it is determined whether the value of a timer variable storage area described later is 10 or more. When the value of the timer variable storage area is 10 or more, the process proceeds to step S805, and when the value of the timer variable storage area is less than 10, the process proceeds to step S802. In step S805, 0 is stored in the timer variable storage area.

  In step S806, effect data update processing is performed. In this effect data update process, the contents of a command storage area, which will be described later, are confirmed, and it is determined whether or not a random clock abnormal command has been received from the main control unit 300. When the random clock abnormal command is received, the random clock is abnormal due to the decorative symbol display device 110, the shielding means 250, the speaker 416, the various lamps 420, the effect movable body of the effect device 200, and the like. The operation control data for notification to the outside is updated. On the other hand, if the random clock abnormality command has not been received, the variation number stored in the variation pattern selection process described later, the temporary stop symbol combination, and the stop symbol combination type are updated and the decorative symbol variation Updating of the operation control data for controlling the effect by the decorative symbol display device 110, the shielding means 250, the speaker 416, the various lamps 420, the effect movable body of the effect device 200, and the like based on the elapsed time since the display was started. I do.

  In step S806, a command to be output to the sub-control unit 500 in the process of step S803 to be executed next time so that the decorative symbol variation display is performed in the manner indicated by the determined effect information (for example, stopping the decoration 7 on the left side). For example, a command for operating the shielding means 250 and a command for operating the shielding means 250) are stored in a liquid crystal command storage area provided in the RAM 408, and the speaker 416, various lamps 420, and a movable body for production are described in steps S805, 806, and 807 described later. Prepare to control. In addition, 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 S807, a sound output process is performed. In this sound output process, the audio data to be output to the speaker 416 included in the speaker control information acquired in step S806 is set in the output port of the I / O 410, and the sound source IC 418 performs output control of the speaker 416. For example, when the operation control data for notifying the outside that the random number clock is abnormal is set in step 806, a sound (for example, a warning) is displayed using the speaker 416 that the random number clock is abnormal. Sound).

  In step S808, lamp control processing is performed. In this lamp control process, data indicating lighting / extinguishing of lamps to be output to various lamps 420 included in the various lamp control information acquired in step S806 is set in the output port of the I / O 410, and various lamps 420 are stored. The display circuit 422 is controlled to turn on and off. For example, when the operation control data for notifying the outside that the random number clock is abnormal is set in step 806, light (for example, using various lamps 420 to indicate that the random number clock is abnormal). (Flashing display).

  In step S809, an effect drive control process is performed. In the effect drive device control process, data indicating the operation timing included in the control information for the effect movable body acquired in step S806 is set in the output port of the I / O 410, and the effect movable object and the like are set. The drive device 424 for effect production controls the drive device 424 for each effect to be driven. For example, when the operation control data for notifying the outside that the random number clock is abnormal is set in the step 806, the fact that the random number clock is abnormal is moved using the effect movable body (for example, , Stop).

  Sub-control unit 400 repeatedly executes the processes of steps S802 to S809 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 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.

  In step S810, the contents of a command storage area to be described later 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 S812. If an unprocessed command does not remain in the command storage area, the process ends and returns to the sub-control unit main process. .

  FIG. 15C is a flowchart showing the flow of the variation pattern selection process, and FIG. 15D is a flowchart showing the flow of the symbol stop process. In step S821, based on the type of unprocessed command to be processed next among the unprocessed commands stored in the command storage area, the variation pattern selection process shown in FIG. This is executed based on the symbol variation start command), symbol stop processing shown in FIG. 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 performed in some cases. Other processing is omitted here.

  In step S841 of the variation pattern selection process, the value of the jackpot flag, the probability variation flag, and the timer number included in the unprocessed command are extracted and stored in the respective storage areas of the RAM 408. In addition, referring to the above-described variation number selection table or symbol determination table, effect data (in this embodiment, variation number, temporary stop symbol / stop symbol combination, etc.) is selected and stored in a storage area provided in the RAM 408. After that, the process ends.

  In step S861 of the symbol stop process, the three decorative symbols constituting the combination of the stopped symbols stored in the symbol storage area are displayed on the left, middle, and right symbol display areas 110a to 110c of the decorative symbol display device 110. The setting is made to display in the area, and the process ends. 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, strobe interrupt processing 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. In step S861 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 S881 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.

<Variable update interrupt processing>
Next, variable update interrupt processing 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 variable update interrupt processing.

  The sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (once every 2 ms in this embodiment), and executes the variable update interrupt processing at a predetermined cycle triggered by this timer interrupt. To do.

  In step S901 of the variable update interrupt process, 1 is added to the value of the timer variable storage area of the RAM 408 and the result is stored in the original timer variable storage area. Therefore, in step S304, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  As described above, the pachinko machine 100 according to the first embodiment counts the count value based on the clock generation circuit (for example, the crystal oscillator 314a) that generates a clock signal having a predetermined frequency and the clock signal. When the counter circuit (for example, the random number circuit 316), the clock signal monitoring circuit (for example, the frequency monitoring circuit 316a) for monitoring the abnormality of the clock signal, and the clock signal monitoring circuit detect the abnormality of the clock signal, A gaming table comprising: notification command output means (for example, CPU 304) for outputting notification command information (for example, control command) for notifying that the clock signal is abnormal.

  According to the pachinko machine 100 according to the first embodiment, since it is possible to grasp the presence / absence of an abnormality in the clock signal based on the notification command information, it is easily possible from the outside that there is an abnormality in the clock used for game control. Sometimes you can know.

  In addition, the gaming machine (for example, the pachinko machine 100) according to the first embodiment can generate a first clock generation circuit (for example, a crystal oscillator 314b) that can generate a first clock and a second clock.

By comparing the frequency of the clock obtained based on the system clock with the frequency of the second clock, A clock monitoring circuit (for example, frequency monitoring circuit 316a) capable of determining whether there is normal or not, clock state storage means (for example, RAM 308) capable of storing a clock state indicating whether or not the second clock is abnormal, and the clock state storage Output means capable of outputting at least a predetermined signal when the clock state stored in the means indicates abnormality, the system clock generation circuit, the random number update circuit, the CPU, and the clock A microprocessor (e.g., a basic circuit 302) including at least a monitoring circuit, the clock state storage means, and the output means, wherein both the first clock generation circuit and the second clock generation circuit are connected to the microprocessor; Not included and the microprocessor receives the first clock. At least a first clock input terminal capable of inputting the second clock, and the first clock input terminal from the first clock generation circuit is a first clock input terminal. The second clock input terminal from the second clock generation circuit is connected by a second signal line, and the second signal line is longer than the length of the first signal line. The game stand is characterized in that the signal line is longer.

  According to the gaming machine according to the first embodiment, whether or not the second clock is abnormal can be detected more reliably than before, and it is possible to prevent fraud and the like and perform a stable game control. There are cases where it is possible. Further, by making the second signal line longer than the first signal line, the second clock (random number clock) is more random even if the waveform is disturbed due to noise or attenuation. There are cases where a value can be generated, and there is a case where a fraud countermeasure can be taken conversely because a physical factor affects the count value. In addition, by making the first signal line shorter than the second signal line, an accurate and regular first clock can be input to the microprocessor so that the CPU and other components do not malfunction. Yes, there are cases where a stable game control can be performed. In addition, disposing the second clock generation circuit at a position farther than the first clock generation circuit makes it easier for fraud to occur or the frequency of the second clock input to the microprocessor is abnormal. In the present invention, the clock monitoring circuit monitors whether the second clock (random number clock) is abnormal, so that the abnormality can be detected quickly. In some cases, stable game control can be performed.

  Further, the gaming machine (for example, the pachinko machine 100) according to the first embodiment generates at least a first clock generation circuit (for example, a crystal oscillator 314b) capable of generating at least a first clock and a second clock. A gaming table comprising a possible second clock generation circuit (for example, a crystal oscillator 314a) and a microprocessor (for example, a basic circuit 302) including at least a CPU (for example, a CPU 304), The processor includes at least a system clock generation circuit (for example, clock circuit 340), and the microprocessor includes at least a random number circuit (for example, random number circuit 316). A clock monitoring circuit (eg, frequency monitoring circuit 316a) at least The microprocessor is provided with a first clock input terminal capable of inputting the first clock, and the microprocessor is capable of inputting the second clock. The system clock generation circuit can generate at least a system clock based on the first clock, and the random number circuit can be based on the second clock. The random number can be updated at least, and the CPU can execute at least a game control process based on the system clock, and the clock monitoring circuit can detect whether or not the second clock is abnormal.

Connected by a line, the length of the second signal line is at least longer than the length of the first signal line, and the random number circuit is capable of generating at least a plurality of types of random numbers It is a game stand characterized by that.

  According to the gaming machine according to the first embodiment, whether or not the second clock is abnormal can be detected more reliably than before, and it is possible to prevent fraud and the like and perform a stable game control. There are cases where it is possible. Further, by making the second signal line longer than the first signal line, the second clock (random number clock) is more random even if the waveform is disturbed due to noise or attenuation. There are cases where a plurality of types of values can be generated, and there are cases where a countermeasure against fraud can be taken conversely because a physical factor affects the count value. In addition, by making the first signal line shorter than the second signal line, an accurate and regular first clock can be input to the microprocessor so that the CPU and other components do not malfunction. Yes, there are cases where a stable game control can be performed. In addition, disposing the second clock generation circuit at a position farther than the first clock generation circuit makes it easier for fraud to occur or the frequency of the second clock input to the microprocessor is abnormal. In the present invention, the clock monitoring circuit monitors whether the second clock (random number clock) is abnormal, so that the abnormality can be detected quickly. In some cases, stable game control can be performed.

  The clock monitoring circuit may be capable of outputting an abnormal signal.

  With such a configuration, it may be possible to easily know from outside that there is an abnormality in the clock used for game control.

  A first control unit (for example, the main control unit 300); a second control unit (for example, the sub-control unit 400) capable of at least performing control according to a command from the first control unit; The microprocessor may be provided in the first control means.

  With such a configuration, even in a gaming machine equipped with two control means, it is possible to perform abnormality notification and easily know from the outside that there is an abnormality in the clock used for game control There is.

  The first control means may be capable of performing abnormality notification when the abnormality signal is output.

  With such a configuration, since the abnormality notification can be performed from the first control means, it may be possible to easily know from the outside that there is an abnormality in the clock used for game control.

  The first control means is capable of outputting a command command for instructing the second control means to execute abnormality notification when the abnormality signal is output, and the second control means May be capable of executing abnormality notification in response to the input of the command command.

  With such a configuration, abnormality notification can be performed from the second control means, and therefore it may be possible to easily know from the outside that there is an abnormality in the clock used for game control.

  In addition, a clock signal state storage unit (for example, an internal information register) that stores a clock signal state indicating the presence or absence of abnormality of the clock signal monitored by the clock signal monitoring circuit, the notification command output means, The notification command information is output when the clock signal state stored in the clock signal state storage unit indicates that there is an abnormality (for example, when the clock signal state bit of the internal information register is set to 1). You may comprise as follows. With this configuration, since it is possible to store the presence / absence of an abnormality in the clock signal, it is possible to detect the presence / absence of an abnormality in the clock signal at an arbitrary timing, and to appropriately determine the presence / absence of the abnormality. Sometimes it can be done at the timing.

  The clock signal monitoring circuit further includes a second clock generation circuit (for example, a crystal oscillator 314b) that generates a second clock signal different from the clock signal, and the clock signal and the second clock signal are input to the clock signal monitoring circuit. The clock signal monitoring circuit may be configured to determine whether the clock signal is abnormal by comparing the frequency of the clock signal with the frequency of the second clock. With such a configuration, it may be possible to easily determine whether there is a clock abnormality. In addition, it may be possible to determine an abnormality in the second clock generation circuit.

  The second clock signal may be a system clock signal for operating a control unit including at least the notification command output unit. With such a configuration, the system clock can be used also as the second clock for determining the abnormality of the clock, and thus the wiring may be simplified. Further, it may be possible to determine an abnormality of the system clock.

  In addition, voltage monitoring means (for example, voltage monitoring circuit 336) for monitoring whether or not the voltage value of the power supplied to the game table is equal to or higher than a predetermined voltage value, and information can be temporarily stored. Temporary storage means (for example, RAM 308), and the information stored in the clock signal state storage unit is the information when the voltage monitoring means determines that the voltage value is less than the predetermined voltage value ( For example, when a part of the information stored in the temporary storage means is rewritten (for example, at the time of initial setting), all the game information stored in the temporary storage means is erased. In some cases (for example, when the RAM is cleared), the data may be erased only. With such a configuration, the presence or absence of a clock abnormality can be detected at the time of recovery from a power interruption or after initial setting, and the clock abnormality may be more reliably known.

  Moreover, when the notification command information is input from the notification command output unit, a notification unit (for example, various lamps, a speaker, and a movable body) that notifies the outside that the clock signal is abnormal may be further provided. . With such a configuration, it may be possible to more reliably notify clock abnormality.

  In addition, it further includes profit information output means for outputting profit information (for example, the number of credits, the number of bets, the number of rounds in a big hit, etc.) relating to the profit of the player, and the notification means outputs the profit information from the profit information output means. Is input to the outside when the information related to the player's profit is notified and the notification command information is input from the notification command output means during the notification of the information related to the player's profit. It may be configured to notify the outside that the clock signal is abnormal without stopping the notification of the information regarding the profit. With such a configuration, it is possible to prevent a situation in which a notification command signal is output during notification of information relating to the player's profit and the player is disadvantaged, and the player's Profits may be secured.

  The notification command further includes: lottery means for performing lottery using the count value acquired from the count circuit; and symbol change means for changing or stopping the display mode of the symbol according to the lottery result by the lottery means. The output means does not output the notification command signal when the clock signal monitoring circuit detects an abnormality of the clock signal during the change of the design by the design change means, and the change of the design by the design change means does not occur. The notification command signal may be output after being stopped. With such a configuration, it is possible to prevent a situation in which a notification command signal is output during a symbol change and the game is interrupted, and the player's profit may be secured.

  Further, at least the counter circuit, the clock signal monitoring circuit, and the notification command output means may be housed in one package. With such a configuration, it may be possible to prevent fraudulent acts that do not detect clock anomalies by crafting signal lines connected to the clock signal monitoring circuit.

  It should be noted that the configuration of the gaming table according to the present invention is not limited to the configuration of the gaming table according to the above embodiment. Therefore, for example, the “notification unit” according to the present invention is not limited to the speaker 416, the various lamps 420, and the moving movable body for production in the above-described embodiment. A lamp, a speaker, a movable object, a variable display, etc. controlled by the control unit 400, the sub control unit 500, and the payout control unit 550) are also included. Further, notification may be performed using one, a plurality, or all of these notification means. Furthermore, it is not limited to the notification by these notification means, for example, the notification command output means may be configured to output the notification command information to an external information terminal board provided on the game table. In this case, notification command information is output to various devices (for example, a game information display device, a hall computer, etc.) outside the gaming table via the external information terminal board, and notification is performed by various devices outside the gaming table. You can also

  In addition, the timing of notification by the notification means is not limited to the timing shown in the above-described embodiment. For example, notification of abnormality of the clock signal is performed, and other notifications (for example, notification regarding various errors, notification regarding fraud) May be prioritized. Further, the notification of the abnormality of the clock signal may be performed simultaneously with other notifications or later than other notifications, or may be performed a plurality of times alternately with other notifications.

  The timing for determining whether or not the clock signal is abnormal is not limited to the timing shown in the above embodiment. For example, when the CPU acquires (latches) the count value (random number) of the random number circuit, the power is turned on. At a later initial setting (specifically, when the RAM is cleared, after the low voltage signal is turned off, etc.), at any timing within the interrupt process (specifically, when the interrupt starts, when various lottery processes are executed, random number latch process) Before or after the end of an interrupt), any timing within the main loop (specifically, when the main loop starts, when the main loop ends, when interrupts are disabled, etc.) It may be when the start lever is available. Moreover, you may detect abnormality by the process of several places combining said timing.

  Also, the mode of notification by the notification means is not limited to the mode shown in the above-described embodiment. For example, in addition to directly reporting the abnormality of the clock signal, it is reported that there was some fraud. Or, it may be reported as another abnormality.

  In addition, the purpose of use of the count value acquired from the random number circuit is not limited to the purpose of use shown in the above embodiment. For example, a special drawing lottery, a general drawing lottery, a jackpot type (whether or not it is a probability variation) lottery, and production It may be used as a random number for predetermined lottery such as lottery.

  Further, the mode in the case of detecting the abnormality of the clock signal is not limited to the mode shown in the above embodiment, and for example, the launching device is stopped or not stopped, the dispensing device is stopped or not stopped. , To stop or not to stop the special figure or ordinary figure change, to display or not to display the special figure or ordinary figure, to rewrite all the pending special figure variable game or universal figure variable game wins, After the winning of special figure variable game or normal figure variable game is rewritten to lose, special figure variable game or general figure variable game is stopped, the changing symbols continue to change, and if the change stops, the game is stopped, variable If the slot machine, which will be described later, closes the winning opening 130, the selector is stopped or not stopped, the hopper is stopped or not stopped, the ball is inserted. The combination of aspects such as for sensing the mouth prize or not perform, are also included.

  Further, when the special figure is changing at the time when the abnormality of the random number clock is detected, a process due to the abnormality of the random number clock may be added after the change is completed. At least, the special figure in the fluctuation is the special figure fluctuation that started before detecting the abnormality of the random number clock (in other words, the special figure fluctuation that fluctuates based on the random number value acquired before judging that the random number clock is abnormal) Therefore, there is a high possibility that the random number is obtained when the random number clock is normal. Therefore, it is not fair for the player to make the processing corresponding to the abnormality of the random number clock before and after the end of the variation of the special figure the same. Therefore, the processing for the abnormality of the random number clock performed after the end of the variation of the special figure may be different from the processing for the abnormality of the random number clock performed before the end of the variation of the special figure. The processing for the abnormality of the random number clock that is performed after the end of the game is a process that is more disadvantageous to the player than the processing for the abnormality of the random number clock that is performed before the end of the fluctuation of the special figure (for example, after the abnormality determination of the random number clock Or the addition of a process for stopping payout). In addition to “the special figure fluctuation started before detecting the abnormality of the random number clock” mentioned here, “the special figure fluctuation suspended before detecting the abnormality of the random number clock” may be added. This is because the reserved special symbol also changes based on the random number value acquired before determining that the random number clock is abnormal.

  In this embodiment, there is one special symbol corresponding to the first start port and the second start port. However, the first design port corresponds to the first start port and the second start port. A special symbol and a second special symbol may be provided. In this case, the first special symbol may change in preference to the second special symbol. To change preferentially means that the first special symbol is not changing (not included during fixed display) and the first special symbol has no number of reserved balls as a condition for starting the change of the second special symbol. Etc. In this case, if there is an abnormality in the random number clock monitoring circuit when there are three holds in the first special symbol and one hold in the second special symbol, When a game ball enters, there are four holds for the first special symbol. In this case, since the priority order of the change is determined, there is a problem that the fourth special symbol is changed based on the hold after the abnormality determination without changing the second special symbol. is there. Here, when there are a plurality of special symbols and the priority order of variation is determined, if a special symbol hold with a subordinate priority order is obtained before the random number clock is judged abnormal, The above-described “process to be performed after detecting the abnormality of the random number clock” may be performed even if the value does not fluctuate. If this is not done, there is a possibility that the “process to be performed before detecting the abnormality of the random number clock” will be performed forever.

  In addition, the mode after detecting the abnormality of the clock signal is not limited to the mode shown in the above embodiment. For example, unless RAM clear is executed, recovery from the clock signal abnormality may be impossible. The random number clock abnormality information may be stored at the time of power interruption after the abnormality detection, and the RAM may be cleared when the random number clock abnormality information is stored at the time of power restoration.

  A value obtained by processing the count value obtained by latching by a predetermined method may be used as a random number. For example, processing may be performed by adding a value acquired by a soft counter updated at a predetermined interrupt cycle. Even in this case, when the update cycle of the soft counter is later than the count update cycle of the random number generation circuit, it is desirable to stop the random counter because there is a problem that the random number is likely to be targeted.

  An interrupt signal may be output to the CPU based on the fact that the random number is latched and stored in the random value register. In the processing performed by this interruption, random number clock frequency abnormality determination processing may be performed.

  Further, the random number circuit chA may be updated with a system clock, the random number circuit chB with a random number clock, the random number circuit chA may be used as at least a special symbol lottery random number counter, and the random number circuit chB may be used as at least a normal symbol lottery random number counter. . In addition, the value obtained from the normal symbol lottery counter may be a value processed by a predetermined method.

  Further, the latch of the random number value may be acquired by a method of acquiring from a program instead of the random number latch input signal. In this case, it is determined whether or not there is an abnormality in the random number clock before acquisition from the program. If there is an abnormality, the latch may not be performed.

  Further, a plurality of (for example, two) start ports may be provided, and a plurality of (for example, two) special symbols may be provided for each of the start ports. In this case, if the first special symbol is changing or the change start condition is satisfied (such as when there is a holding ball of the first special symbol), the second special symbol is not changed. , You may give priority to the fluctuation | variation of a 1st special symbol. In addition, the first start port corresponding to the first special symbol may be in a state where it is easier to enter the ball than the second start port corresponding to the second special symbol. The “special symbol” can be replaced with the “normal symbol” and applied.

  In addition, the start value of the first round of the random number circuit is fixed to a predetermined value (for example, 0001h), and the predetermined value in the lottery data is the most unfavorable for the player (for example, if the big hit lottery is lost) It may be. In this way, even if the random number counter is not updated at all due to disconnection etc. among the abnormalities of the random number clock monitoring frequency, the game store can suffer disadvantages if the system is reset There is an effect that the nature is reduced.

  In addition, when there is an abnormality in the random number clock frequency, the abnormality is notified, and when the start value of the first round of the random number circuit is the most disadvantageous for the player, the abnormality is notified. The abnormality information stored in the storage unit for performing the monitoring is a flag for monitoring whether or not the system reset is performed at the time of initial setting. Even if it determines, you may make it not alert | report. In this case, the player is less likely to suffer a disadvantage.

  Also, in the case of a slot machine, which will be described later, if an abnormality in the random number clock frequency is detected when a winning flag that gives a profit to the player is established, a winning flag (BB flag or the like) having a high advantage is advantageous. It may be rewritten to a winning flag with a low degree (such as a lost flag). Further, a gaming state with a high degree of advantage (BB gaming state or the like) may be rewritten to a gaming state with a low degree of advantage (such as a normal game state).

  Further, in the case of a slot machine described later, if an abnormality in the random number clock frequency is detected while the reel is changing, the change of the reel may be stopped immediately. The stop control here is performed so that the symbol combination corresponding to the winning combination is not displayed. Specifically, it starts counting from a predetermined timer start time (such as when the reel starts to change or when the reel starts to change at a constant speed) and automatically when a predetermined time has passed. At least a part of stop control (for example, a reel stop table for stopping the reel at a predetermined position) used in the automatic stop for stopping the reel that is fluctuating may be used. Moreover, it is not necessary to divert. Further, it may be stopped so that the symbol combination corresponding to the winning winning combination is not displayed.

  Further, in the case of a slot machine to be described later, if an abnormality in the random number clock frequency is detected while the reels are changing, it may be notified that all the reels have stopped and then abnormal.

  Further, when an abnormality in the random number clock frequency is detected while the variable display device (liquid crystal display or the like) is shielded by a shielding member (such as a shutter), at least the abnormality notification in the variable display device is not visible. You may make it be in a shielding state. At this time, the notification may be performed after entering the non-shielding state, the notification may be performed during the movement from the shielding state to the non-shielding state, or the notification may be performed from the shielding state.

  In addition, when an abnormality in the random number clock frequency is detected during a so-called demonstration production performed when a game is not performed for a predetermined period, a notification regarding the abnormality is sent to an external device (for example, a hall computer, a game information display device, etc.). While outputting externally, no notification is made in the gaming machine, and at least in the case of detecting an abnormality in the random number clock frequency in addition to the demonstration effect, a notification regarding the abnormality is notified by a predetermined notification device (such as a variable display) in the gaming machine. You may go. Since it is unlikely that an abnormality has occurred due to an unauthorized act by an unauthorized player during the demonstration screen, it is only necessary for the person concerned with the amusement shop to check. For the same reason, if an abnormality in the random number clock frequency is detected when the door is not open, the random number clock frequency is output to the external device while not being notified in the gaming machine. May be notified by a predetermined notification device (for example, a variable display) in the notification gaming machine regarding abnormality. In addition, when an abnormality in the random number clock frequency is detected during the initial setting process performed based on power-on, both notification in the gaming machine and notification by external output may be performed. When the random number clock frequency abnormality occurs, in most cases, the fraudster accesses the game board and destroys the random number clock or disconnects the bus connecting the random number clock and the CPU. This is because an abnormality in the random number clock at the time of power-on is very likely to be fraudulent.

  In the case of a slot machine, which will be described later, an abnormality in the random number clock may be determined by the gaming state update process.

  In addition, a control unit (such as a payout control unit and a sub-control unit) that inputs a command related to an abnormality in the random clock frequency from a control unit (such as a main control unit) that detects an abnormality in the random clock frequency is used for random numbers when the power is turned off. If the clock frequency abnormality is stored, the information is stored so that it can be backed up.When the random number clock frequency abnormality is stored when the power is turned on, the random frequency clock frequency abnormality is notified as an initial operation. May be. In other words, if an abnormality in the random number clock frequency is detected at the time of power interruption, the abnormality in the random number clock frequency is notified without waiting for a command from the control unit that detects the abnormality in the random number clock frequency when the power is turned on. May be. As a result, for example, after detecting an abnormality in the random number clock frequency, even when the harness connecting each control unit is disconnected, each can be notified independently. In addition, notification can be performed during the period from when the power is turned on to when the command is received from the main control unit. Note that the control unit (main control unit) that detects an abnormality in the random number clock frequency does not clear the abnormality in the random number clock frequency unless at least a part of the RAM area (or the entire RAM area that is open to the user) is cleared. The notification may not be stopped. In addition to the RAM clear, a control unit (such as a payout control unit and a sub-control unit) that inputs a command related to an abnormality in the random number clock frequency receives a command indicating that the random number clock frequency is normal from the main control unit. When transmitted, the notification of abnormality in the random number clock frequency may be terminated. As a result, it is possible to recover from the abnormality simply by correcting the abnormality of the random number clock frequency and clearing the main control unit from the RAM.

  In addition, when an abnormality in the random number clock frequency is stored when the power is turned on, a part of the initial setting performed when the abnormality in the random number clock frequency is not stored may not be performed. For example, when the abnormality of the random number clock frequency due to the movement of the movable object is not notified, the initial setting operation regarding the movement of the movable object may not be performed. Thereby, the abnormality notification of the random number clock frequency can be performed more quickly.

  Further, the arrangement position of the random number clock on the board may be arranged farther from the one-chip microcomputer than the arrangement position of the system clock on the board. Generally, the farther the wiring length is, the more likely the waveform is disturbed for reasons such as noise and attenuation. However, for random number clocks, random values may be drawn even when the waveform is disturbed due to noise, attenuation, etc., so the physical factor affects the count value. May have an effect on fraud countermeasures. . On the other hand, since the system clock is required to be as accurate and regular as possible so that the CPU and other components do not malfunction, it is desirable that the system clock be disposed closer to the one-chip microcomputer. Therefore, it is desirable to arrange the system clock with priority over the random number clock (in the vicinity). Here, disposition of the random number clock at a distant position may make fraud easily occur, and the frequency input to the one-chip microcomputer may become an abnormal value. Since the random number clock is monitored, the abnormality can be detected quickly, and the amusement shop side can quickly respond by giving notification. Further, for example, when the frequency monitoring circuit 316a is provided with a monitoring function of the SCLK by the random number clock RCK, such as the SCLK must be at least twice the clock frequency of the RCK, the SCLK can be monitored. .

  In addition, when an abnormality in the random number clock frequency is detected in an initial setting process performed based on power-on, and in a case where a predetermined process other than the initial setting process (for example, a timer interrupt process) is detected, a notification mode is provided. May be different. Specifically, if it is detected in a predetermined process other than the initial setting process, it notifies that the random number clock frequency is abnormal, and if it is detected in the initial setting process, it notifies that the RAM clear is urged. Also good.

  Further, when an abnormality in the random number clock frequency is detected, information indicating that the abnormality has been detected is stored in a predetermined storage area (such as a RAM), the first notification is made, and the information is also stored even after the power is cut off. May be backed up and stored. In this case, it is determined whether or not there is information that an abnormality has been detected in the initial setting process performed based on power-on. If it is determined that there is an abnormality, a second notification is performed. Also good. Here, the first notification may be a notification that the random number clock frequency is abnormal, and the second notification may be a notification that the RAM is cleared. The first notification includes a process of notifying at least the external device that the random number clock frequency is abnormal, and the second notification notifies at least the external device that the random number clock frequency is abnormal. Processing may not be included. By doing in this way, it can avoid that a hall computer acquires the same information many times, for example.

  In addition, when an abnormality is detected in the random number clock frequency, information indicating that the abnormality has been detected is stored in a predetermined storage area (such as a RAM), and the information is backed up and stored even after the power is cut off. When determining whether or not to execute RAM clear in the initial setting process based on the above, it is determined whether or not the random number clock frequency is still abnormal by referring to the internal information register. However, the RAM clear may not be executed when the process continues. By doing so, the abnormality of the random number clock frequency can be continuously notified, or the notification of the abnormality of the random number clock frequency is once ended, and the abnormality of the random number clock frequency is detected and notified again. In the meantime, it is possible to avoid that the abnormality of the random number clock frequency is not notified.

  In addition, when the power is turned on, the operation of the random number clock and system clock may become unstable, so there is a possibility that the abnormality monitoring circuit may erroneously judge that it is abnormal even though it is not abnormal. Is also expensive. For this reason, the clock signal status bit in the internal information register is cleared at the time of initialization, and the period from when the random number clock monitoring circuit determines whether the random number clock is abnormal again and whether to write the bit to the internal information register has elapsed Later, the random number clock abnormality determination may be performed based on the clock signal status bit of the internal information register. In this case, if an abnormality has occurred in the random number clock, information indicating an abnormality is set again in the internal information register. It should be noted that the elapsed time may be obtained by performing other processing, or may wait for the elapsed time by a wait by a predetermined wait timer. If a bit is written in the internal information register without waiting for the period to elapse, it is not necessary to wait for the period. It is desirable that the timing for clearing the clock signal status bit of the internal information register is at least after the low voltage signal is turned off. Further, since the same problem occurs at the time of power interruption, it is desirable not to store information indicating that the clock frequency is abnormal based on the clock signal status bit of the internal information register at the time of power interruption. In other words, “a process for clearing the memory of the clock state storage unit at power-on” may be provided. Further, “after the process of clearing, it is not determined whether or not the clock signal state is abnormal for a predetermined period”. In addition, it is desirable to “perform at least the clearing process after the low voltage signal is turned off”. Further, it is desirable that “when the power is interrupted, an abnormal state is not stored in the clock state storage unit”. As a method for clearing the clock signal status bit of the internal information register, a value indicating normal is written to the clock signal status bit of the internal information register, and when the clock signal status bit of the internal information register is read, the bit is You may use being cleared. That is, the memory of the clock state storage unit may be read when the power is turned on, and the abnormality of the random number clock may not be determined based on the read information. In other words, it is read only for the purpose of clearing.

  Also, in this embodiment, the P0 terminal has a special figure 1 start opening detection signal that is output when a ball enters the special figure 1 start opening, and the P1 terminal has a ball entering the special figure 2 start opening. Although the special figure 2 starting opening ball detection signal output in the case is outputted, the latched special figures 1 and 2 may obtain random numbers from different channels. For example, the random number in FIG. 1 may be acquired from channel A, and the random number in FIG. 2 may be acquired from channel B.

  Also, a random number for the special figure 1 lottery is acquired from the channel A of the P0 terminal, and a lottery value regarding the special figure fluctuation and a random number of the jackpot type are obtained from the channel B of the P0 terminal based on the winning of the special figure 1 winning entrance. Random values that are selected in a random manner may be acquired. In this case, it is desirable that the same combination of random numbers is not always acquired for the channel A and the channel B by changing the arrangement and cycle of the random number values. In the case of a slot machine to be described later, a winning combination lottery random number may be acquired from the channel A of the P0 terminal to which the start lever detection signal is input, and an effect lottery random number may be acquired from the channel B of the P0 terminal. The combination of terminal connections is not limited to this. In the case of a pachinko machine, a jackpot type random number and various timer random numbers may be acquired from the random number circuit 316. Further, a random number may be acquired from the random number circuit 316 in order to draw a start value of a predetermined random number update cycle. The start value is a value for determining from which numerical value the update starts when a predetermined random number updates a predetermined update range (for example, 1 to 100). Further, in the above embodiment, it is determined whether or not a specific winning opening has been won based on whether or not a predetermined pattern (OFF → ON → ON) has been detected, but the present invention is not limited to this. . For example, the determination may be made by edge detection (ON → OFF, OFF → ON). When making a determination by edge detection, it is preferable to read the value of the random number latch register and acquire the random number after confirming that the random number has been latched.

  The random number clock frequency abnormality monitoring circuit may be arranged in one chip. By doing so, it is possible to prevent fraud such that the abnormality monitoring function is disabled by disconnecting the signal line connecting the abnormality monitoring circuit and the CPU.

  In addition, the abnormality in the random number clock frequency is caused by the fact that the random number clock is not input to the random number circuit due to the disconnection of the connection line between the random number clock and the random number circuit (frequency 0). It also includes that the random number clock is no longer input to the random number circuit due to the destruction of the random number clock or the removal of the random number clock. In addition, the random number clock is input to the random number circuit by replacing the random number clock with a low frequency random number clock, but the frequency becomes lower than a predetermined value, making it easier to target random numbers. Suppose it is abnormal. Note that a case where the system clock is input to a place where the random number clock is to be input due to an illegal act may be abnormal. In the present embodiment, since random number value fetching (latching) based on software is not performed, the random number latch selection register and the random number value fetching register are not referred to. However, software-based latching may be performed. In this case, before the random number is obtained from the latch circuit, the abnormality determination of the frequency of the random number clock and the determination of the value of the random number acquisition register may be performed. Specifically, the random number may be acquired from the latch circuit only when the random value acquisition register indicates that the acquisition has been completed and the clock frequency is normal. Also, it indicates that the random number value acquisition register has not acquired, and the clock frequency is normal, the random value acquisition register indicates that it has been acquired, and the clock frequency is abnormal, and the random value acquisition The notification mode may be partially changed depending on whether the register indicates that it is not captured and the clock frequency is abnormal.

  Since the random interrupt is not used, the random interrupt control register is not referred to. However, a random interrupt may be used. In this case, an abnormality in the clock frequency may be determined in response to random number interrupt processing. Further, in the slot machine described later, only when the start lever is received (game medal insertion process S110 described later), the interrupt permission setting may be set to permit the interrupt permission setting. Further, since the random number sequence is not changed, the random number sequence change register is not referred to, but the random number sequence may be changed.

  In addition, the length of the wiring pattern connecting the activation signal output circuit 338 and the basic circuit (one-chip microcomputer) 302 is longer than the length of the wiring pattern connecting the crystal oscillator 314a and the basic circuit (one-chip microcomputer) 302. Also good. The length of the wiring pattern connecting the power monitoring circuit 336 and the basic circuit (one-chip microcomputer) 302 may be longer than the length of the wiring pattern connecting the crystal oscillator 314a and the basic circuit (one-chip microcomputer) 302.

  In addition, a specific operation was performed by a game store clerk, a shipping inspector, or an installation inspector to determine whether or not the clock signal state stored in the clock signal state storage unit indicates abnormality. You may comprise so that it may carry out only in the case. In this case, until the above-mentioned specific operation or another specific operation is performed again, the predetermined operation prohibition state in which the predetermined game control operation is not performed, and the notification indicating that the clock signal is abnormal are continued. One or both of the notification continuation states to be performed may be set. Here, the specific operation is a power-on operation, a power-off operation, an operation of a specific operation unit provided in the gaming machine (for example, a RAM clear switch for instructing a RAM clear, an error release switch, etc.), and a separate operation from the gaming machine One or more of specific collation signal input operations from an external device may be applied. With this configuration, it may be possible to reliably inspect the occurrence of a hardware abnormality before being known to the player.

  In addition, it may be configured such that the process of determining whether or not the clock signal state stored in the clock signal state storage unit indicates that there is an abnormality is performed during or after execution of a predetermined gaming operation. If it is determined that there is an abnormality in the determination process during or after execution of the predetermined game operation, the determination process during or after execution of the same game operation is not performed until a predetermined condition is satisfied. Also good. Here, the predetermined condition is preferably applied when the above-described specific operation is performed, but other conditions may be applied. By configuring in this way, there may be a case where it is possible to promptly notify a game store clerk that there is a possibility that an illegal game has been performed.

  In addition, the process of determining whether or not the clock signal state stored in the clock signal state storage unit indicates that there is an abnormality is performed by clearing the clock signal state storage unit and then transferring the clock signal state to the clock signal state storage unit. It may be determined by reading whether information indicating that the signal state is abnormal is stored. The clearing and reading may be performed continuously, or the clock signal state is abnormal when the clearing and reading are performed continuously for a predetermined number of times and all the results of the predetermined number of readings indicate information indicating abnormality. Alternatively, it may be determined that the clock signal state is abnormal in the case of information indicating the presence of abnormality at one or a specific number of times or more of the predetermined number of reading results. This clearing and reading-related period after clearing until clearing, and the period after reading until clearing after reading are periods necessary when the CPU processes continuously, or wait time of a predetermined length May be inserted. The period length of the post-clear period and the post-read period may be different, and the period length of the post-read period is made longer than the period length of the post-clear period to ensure the next clear and read quickly. You may comprise as follows. The period length of the post-reading period may be shorter than the period length of the post-clearing period, and the reading may be surely performed and the clearing may be performed quickly. Whether the length of the period after clearing or the length of the period after reading is increased is what the specific game action control before and after the judgment process is, or whether it is a judgment process when a specific operation is performed It is preferable to apply a configuration that is more effective in relation to the notification mode when there is an abnormality.

  Further, one or more of the processes of S101 to S109 and S201 to S220 may be applied to the predetermined game control operation.

  In addition, a notification indicating that the random number clock signal is abnormal based on a determination process performed when the specific operation is performed and a determination process performed when or after a predetermined game operation is performed The notification mode may be different from the notification indicating that the random number clock signal described above is abnormal. The activation signal output circuit 338 may be provided in the basic circuit 302.

  In addition, after receiving a command indicating that an abnormality in the random number clock has been detected, a control unit other than the control unit (main control unit) that detects the abnormality in the random number clock (sub control unit, payout control unit, etc.) It is also possible not to perform notification other than notification of abnormality of the random number clock. Specifically, a command received after a command indicating that an abnormality in the random number clock is detected may be discarded or ignored.

  In addition, when an abnormality of the random number clock is detected in the initial setting process performed based on power-on, the control unit (main control unit) that detects the abnormality of the random number clock is a control that detects the abnormality of the random number clock. After a command indicating that the random number clock has been detected abnormally is output to a control unit other than the unit (sub control unit, payout control unit, etc.), processing related to the game (game ball winning determination etc.) It may not be possible. In addition, the abnormality of the random number clock may not be notified by the main control unit, but the abnormality of the random number clock may be notified by a control unit other than the main control unit. In this case, a control unit other than the main control unit that reports the abnormality of the random number clock may discard or ignore the commands after receiving the command indicating that the abnormality of the random number clock is detected. Note that the main control unit may perform power supply processing based on detection of power-off. As a result, it is possible to reliably notify the abnormality of the random number clock and to make it impossible to continue the game.

  In the above embodiment, an example of a pachinko machine using a game ball as a game medium is shown. However, the present invention is not limited to this, and for example, a medal (coin) as described below is used. The present invention can also be applied to a slot machine used as a game medium.

  Next, the slot machine 100 according to the second embodiment of the present invention will be described.

<Overall configuration>
First, the overall configuration of the slot machine 100 according to the first embodiment will be described with reference to FIG. The figure shows an external perspective view of the slot machine 100.

  The slot machine 100 includes a substantially box-shaped main body 101 and a front door 102 attached to the front opening of the main body 101. Inside the center of the main body 101 of the slot machine 100, three reels (left reel 110, middle reel 111, and right reel 112) having a plurality of types of symbols arranged on the outer peripheral surface for a predetermined number of frames are stored. It is configured to be able to rotate inside. Each of the symbols is printed on the belt-like member at an equal interval, and the belt-like member is attached to a predetermined circular frame member to constitute the reels 110 to 112. When viewed from the player, the symbols on the reels 110 to 112 are generally displayed three in the vertical direction from the symbol display window 113 so that a total of nine symbols can be seen. Then, by rotating the reels 110 to 112, the combination of symbols that can be seen by the player varies. In the first embodiment, three reels are provided in the center of the slot machine 100. However, the number of reels and the installation position of the reels are not limited to this.

  Further, on the outer frame of the symbol display window 113, line display LEDs (not shown) for informing an effective line and a winning line, which will be described later, are arranged by lighting control such as blinking and lighting.

  Further, in the slot machine 100, an optical sensor (not shown) including a light projecting unit and a light receiving unit is provided in the vicinity of each of the reels 110 to 112. The light projecting unit and the light receiving unit of the optical sensor are provided. A light-shielding piece of a certain length provided on the reel passes between them. Based on the detection result of this sensor, the position of the symbol on the reel in the rotation direction is determined, and the reels 110 to 112 are stopped so that the target symbol is displayed on the winning line 114.

  The winning line display lamp 120 is a lamp that indicates an effective winning line. An effective winning line is determined in advance by the number of medals inserted into the slot machine 100. Of the five winning lines 114, for example, when one medal is inserted, the middle horizontal winning line is valid, and when two medals are inserted, the upper horizontal winning line and the lower horizontal winning line are added. When three medals are inserted and three medals are inserted, the five added with the right-down winning line and the upper-right winning line become effective as the winning line. Note that the number of winning lines 114 is not limited to five.

  The start lamp 121 is a lamp that informs the player that the reels 110 to 112 are in a state of being able to rotate. The replay lamp 122 informs the player that the current game can be replayed (the medal insertion is not required) when a replay game that is one of the winning games in the previous game is won. It is a lamp to inform. The notification lamp 123 is a lamp that informs the player that a specific winning combination (for example, a bonus such as BB (Big Bonus) or RB (Regular Bonus)) is won internally in the internal lottery. The medal insertion lamp 124 is a lamp that notifies that a medal can be inserted. The payout number display 125 is a display for displaying the number of medals to be paid out to the player as a result of winning a winning combination. The game number display 126 is an indicator for displaying an error display at the time of inserting a medal, the number of games during the big bonus game (in the BB game), the number of winnings of a predetermined winning combination, and the like. The stored number display 127 is a display for displaying the number of medals electronically stored in the slot machine 100. The reel panel lamp 128 is an effect lamp.

  The medal insertion buttons 130 and 131 are buttons for inserting a predetermined number of medals stored electronically in the slot machine 100. In the first embodiment, every time the medal insertion button 130 is pressed, a maximum of three are inserted one by one, and when the medal insertion button 131 is pressed, three are inserted. The medal slot 134 is an slot for a player to insert a medal when starting a game. That is, the medal can be inserted electronically by the medal insertion button 130 or 131, or an actual medal can be inserted from the medal insertion slot 134. The payment button 132 is a button for adjusting the medals electronically stored in the slot machine 100 and the bet medals and discharging them to the medal tray 156 from the medal payout opening 155. The medal return button 133 is a button that is pressed to remove a medal when the inserted medal is jammed.

  The start lever 135 is a lever-type switch for performing a game start operation. That is, when a desired number of medals are inserted into the medal insertion slot 134 and the start lever 135 is operated, the reels 110 to 112 are rotated as a trigger, and the game is started. The stop buttons 137 to 139 are buttons for performing a stop operation on the reels 110 to 112 that have started rotating by operating the start lever 135, and are provided corresponding to the reels 110 to 112. When any one of the stop buttons 137 to 139 is operated, any one of the corresponding reels 110 to 112 is stopped.

  The door key hole 140 is a hole into which a key for unlocking the front door 102 of the slot machine 100 is inserted. The medal payout exit 155 is a payout exit for paying out medals. The medal tray 156 is a container for collecting medals paid out from the medal payout opening 155. In the first embodiment, the medal tray 156 employs a tray that can emit light.

  The upper lamp 150, the side lamp 151, the center lamp 152, the waist lamp 153, and the lower lamp 154 are decorative lamps for exciting games. The effect device 190 includes, for example, a liquid crystal display device with a door device (shutter) 163 that can be freely opened and closed attached to the front surface. The effect device 190 displays various types of information such as a small role notification. The sound hole 160 is a hole for outputting the sound of a speaker provided inside the slot machine 100 to the outside. On the title panel 162, a pattern for decorating the slot machine 100 is drawn.

<Main control unit 300>
Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to FIGS. 17 and 18.

  The control unit of the slot machine 100 is roughly classified into a main control unit 300 that controls the central part of the game, a sub control unit 400 that controls various devices in accordance with commands transmitted from the main control unit 300, and a sub control. The door / liquid crystal screen display control unit 490 controls the liquid crystal display device 157 and the door device 163 according to the command transmitted from the unit 400.

<Main control unit>
First, the main control unit 300 of the slot machine 100 will be described with reference to FIG. The figure shows a circuit block diagram of the main control unit 300.

  The main control unit 300 includes a CPU 310 that is an arithmetic processing unit for controlling the entire main control unit 300, a data bus and an address bus for the CPU 310 to transmit and receive signals to and from each IC and each circuit, It has the structure described below. The clock correction circuit 314 is a circuit that divides the clock oscillated from the crystal oscillator 311 and supplies it to the CPU 310. For example, when the frequency of the crystal oscillator 311 is 12 MHz, the divided clock is 6 MHz. The CPU 310 operates by receiving the clock divided by the clock correction circuit 314 as a system clock.

  The CPU 310 is connected to a timer circuit 315 for setting a timer interrupt processing cycle for constantly monitoring the sensor and switch states and a motor drive pulse transmission cycle via a bus. When the power is turned on, the CPU 310 transmits the frequency dividing data stored in the predetermined area of the ROM 312 to the timer circuit 315 via the data bus. The timer circuit 315 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 310 at each interrupt time. In response to this interrupt request, the CPU 310 executes monitoring of each sensor and transmission of drive pulses. For example, when the system clock of the CPU 310 is set to 6 MHz, the frequency division value of the timer circuit 315 is set to 1/256, and the data for frequency division of the ROM 312 is set to 44, the reference time for this interrupt is 256 × 44 ÷ 6 MHz = 1. 877 ms.

  Further, the CPU 310 stores a ROM 312 for storing various data such as a program for controlling each IC, lottery data used for internal winning lottery, reel stop position, and temporary data. A RAM 313 is connected. Other storage means may be used for these ROM 312 and RAM 313, and this is the same in the sub-control unit 400 described later.

<Main processing>
Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  Basic control of the game is performed mainly by the Main CPU 310 of the main control unit 300, and the Main CPU 310 repeatedly executes the main processing of FIG.

  In step S1101, initial setting 1 is performed. In this initial setting 1, the stack initial value is set to the stack pointer (SP) of the CPU 310, the interrupt mask is set, the initial setting of various variables stored in the RAM 313, the operation permission to the watchdog timer (WDT), and the initial value are set. Make settings. In step S1102, the value of the WDT counter is cleared, and the time measurement by WDT is restarted.

  In step S1103, whether or not the low voltage signal is on, that is, the voltage value of the power source supplied to the main control unit 300 by the voltage determination circuit 327 is less than a predetermined value (9v in this embodiment). In this case, it is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. Then, when the low voltage signal is on (when the CPU 310 detects that the power supply has been cut off), the process returns to step S1102, and when the low voltage signal is off (when the CPU 310 has not detected that the power supply has been cut off), the step is performed. The process proceeds to S1104.

  In step S1104, initial setting 2 is performed. In the initial setting 2, a process for setting a numerical value for determining a cycle for executing a timer interrupt process, which will be described later, in the timer circuit 315, a setting for permitting writing to the RAM 313, and the like are performed.

  In step 1105, it is determined whether a setting key is accepted based on the state of the setting key sensor. If a setting key has been received, the process proceeds to a setting change process in step S1106. If a setting key has not been received, the process proceeds to step S1107.

  In step S1106, a setting change process is performed. In this setting change process, first, the setting of the function-restricted wait is canceled, the interrupt permission is set, and then the set value is changed.

  In step S1107, it is determined whether or not to return to the state before power interruption (before power supply interruption). And when returning to the state before power interruption, it progresses to step S1108, and when that is not right, it progresses to step S1110.

  In step S1108, after setting a function-restricted wait so that the interrupt function waits for a predetermined time in a timer interrupt process (described later) (after storing information indicating that the function is limited in the predetermined storage area of the RAM 313). In step S1109, processing at power recovery is performed such as resetting the stack pointer stored at the time of power interruption to the stack pointer, and the processing ends.

  In step S1110, game medal insertion processing is performed. Although details will be described later, in this game medal insertion process, the setting of the function-limited weight is canceled and the interrupt permission is set, and then a process related to medal insertion is performed.

  In step S1111, processing relating to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated based on the state of the start lever sensor 321. If it is determined that the start operation has been performed, the number of inserted medals is determined. In step S1112, random number acquisition processing is performed (details will be described later). In step S1113, an internal lottery of a winning combination is performed using the random number value acquired in step S1112 and the lottery data stored in the ROM 312.

  In step S1114, rotation of all reels 110 to 112 is started by reel rotation start processing. At this time, a reel stop control table that defines the stop positions of the reels 110 to 112 is selected based on the result of the internal lottery in step S1113.

  In step S1115, it is checked whether or not the stop buttons 137 to 139 are operated based on the state of the stop button sensor 322, and if it is determined that the stop buttons 137 to 139 are operated, the reel stop selected in step S1114 is performed. Based on the control table, the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped. Then, based on the state of the index sensor 325, it is determined whether or not all the reels 110 to 112 are stopped. If all the reels 110 to 112 are stopped, the process proceeds to step S216. Wait until 139 is operated and all reels 110 to 112 are stopped.

  In step S1116, the winning determination of the symbols of all reels 110 to 112 stopped by pressing the stop buttons 137 to 139 is performed. Here, it is determined that the winning combination has been won when the symbol combination corresponding to the winning combination internally or the winning combination is displayed (displayed) on the activated winning line 114. In step S1117, a medal payout process is performed. In this medal payout process, if a winning combination is awarded, the number of medals corresponding to the winning combination is paid out. In step S1118, control for ending the game and control for shifting the game state are performed. For example, in the case of BB winning or RB winning, preparation is made so that the BB game or RB game can be started from the next time, and in those final games, preparation is made so that the normal game can be started from the next time.

  Thus, one game is completed, and thereafter, the game proceeds by repeating this main process.

  In step S1302, in order to transmit information indicating that there is an abnormality in the random number clock RCK to another control unit (for example, the sub control unit 400), after setting the output of the stop command due to the abnormality in the random number clock, the processing Exit. The sub-control unit 400 that has received the stop command due to the abnormality of the random number clock indicates the abnormality of the random number clock by displaying on the liquid crystal display device 157, sound by the speaker 484, movement by the door device (movable object) 163, and the like. Inform.

  In step S1303, it is confirmed whether or not a game medal has been inserted. If a game medal has been inserted, the process proceeds to step S1304 to perform a bet number increasing process, and if no game medal has been inserted, the process proceeds to step S1305.

  In step S1305, it is confirmed whether or not the settlement button has been operated. If the settlement button has been operated, the process proceeds to step S1306 to perform a game media settlement process. If the settlement button has not been operated, the process proceeds to step S1307. move on.

  In step S1307, it is determined whether or not the number of game medals bet is greater than 0. If yes, the process proceeds to step S1308. If not, the process returns to step S1301.

  In step S1308, it is confirmed whether or not there is a start operation. If there is a start operation, the process ends. If there is no start operation, the process returns to step S1301.

<Random number acquisition processing>
Next, the random number acquisition process in the main process will be described with reference to FIG. This figure is a flowchart showing the flow of random number acquisition processing.

  In step S1401, it is determined whether or not the clock signal status bit is set to 1 by referring to the clock signal status bit in the internal information register. If the clock signal status bit is set to 1 (when the random number clock RCK is abnormal), the process proceeds to step S1402, and if not, the process proceeds to step S1403.

  In step S1402, in order to transmit information indicating that there is an abnormality in the random number clock RCK to another control unit (for example, the sub control unit 400), after setting the output of the stop command due to the abnormality in the random number clock, the processing Exit. The sub-control unit 400 that has received the stop command due to the abnormality of the random number clock indicates the abnormality of the random number clock by displaying on the liquid crystal display device 157, sound by the speaker 484, movement by the door device (movable object) 163, and the like. Inform. In the next step S1403, after the random number is acquired from the random number generation circuit 317, the process is terminated.

  In step S1201, each register of Main CPU 310 is saved in the stack. In step S1202, the value of the input port is acquired and the state of various sensors (medal insertion sensor 320, start lever sensor 321, stop button sensor 322, medal payout sensor 326, etc.) is detected. More specifically, signals output from a plurality of sensors such as a medal insertion sensor 320, a start lever sensor 321, a stop button sensor 322, and a medal payout sensor 326 are input, and the outputs from the plurality of sensors are turned on or off, respectively. Determine whether.

  In step S1203, it is determined whether or not the interrupt function is limited, that is, whether or not a function limit weight is set in the main processing (information indicating that the function is limited is stored in a predetermined storage area of the RAM 313). Or not). If the interrupt function is limited (when a function-limited weight is set), the process proceeds to step S1209 without performing steps S1204 to S1208. If the interrupt function is not limited (a function-limited weight is set). If it has not been set, the process proceeds to step S1204.

  In step S1204, game medal insertion acceptance processing is performed. Although details will be described later, in this game medal insertion acceptance process, processing related to the insertion of game medals is performed based on the current gaming state, the prescribed number of medals required for one game, and the like.

  In step S1205, reel control processing such as rotation control and stop control of the reels 110 to 112 is performed, and in step S1206, other processing is performed. In step S1207, data output to the game lamp 340 (upper lamp 150, side lamp 151, center lamp 152, waist lamp 153, lower lamp 154, saucer lamp 156, etc.) is updated.

  In step S1208, a constant error monitoring process is performed. In this continuous error monitoring process, based on the state of the medal payout sensor 326 detected in step 1202, errors such as a hopper are monitored and error detection information is updated.

  In step S1209, concentrated terminal board signal setting processing is performed. In this concentrated terminal board signal setting process, a state composite signal is generated based on security state information stored in the RAM 313 and serially output. Further, a medal insertion signal, a medal payout signal, and external signals 1 to 4 are generated based on medal insertion information stored in the RAM 313 and output in parallel.

In step S1210, data to be output to the 7SEG display 341 is set. In step S1211, data to be output to the reel motor control unit 330, the hopper motor control unit 331, or the like is set. In addition, referring to the clock signal status bit of the internal information register and when the clock signal status bit of the internal information register is set to 1 (when the frequency of the random number clock is equal to or lower than the frequency of the system clock), the random number It is determined that some abnormality (for example, disconnection of the wiring pattern connecting the random number generation circuit 317 and the crystal oscillator 316) has occurred in the clock for use, and information indicating the error is displayed using the 7SEG display 341. on the other hand,
