  Further, the basic circuit 302 includes a counter circuit (random number circuit) 316 that is used as a hardware random number counter that changes a numerical value in the range of 0 to 65535 every time the random number clock RCK output from the crystal oscillator 314a is received. It is installed (details will be described later).

  In addition, the basic circuit 302 receives signals output from various sensors 318 including a ball detection sensor provided inside each start opening, winning opening and variable winning opening, and results of amplification and comparison with reference voltage Sensor circuit 320 for outputting to the basic circuit 302, a display circuit 322 for performing display control of the special figure display device 114, a display circuit 324 for performing display control of the general map display device 112, and various states Open and close the display circuit 328 for performing display control of the display unit 326 (the ordinary figure holding lamp 116, the special figure holding lamp 118, the high accuracy middle lamp 118, etc.), the second special figure starting port 128, the variable winning port 130, etc. A solenoid circuit 332 for controlling various solenoids 330 to be driven, and a start signal output circuit for outputting a start signal (reset signal) to the CPU 304 when the power is turned on. It connects the reset signal output circuit) 338.

  When the ball detection sensor 318 detects that a ball has won the first special figure starting port 126, the sensor circuit 320 outputs a signal indicating that the ball has been detected to the counter circuit 316. Upon receiving this signal, the counter circuit 316 latches the value of the counter corresponding to the first special figure starting port 126 at that timing, and stores the latched value in the built-in counter value corresponding to the first special figure starting port 126. Store in the register. Similarly, when the counter circuit 316 receives a signal indicating that the ball has won the second special figure starting port 128, the counter circuit 316 latches the value at the timing of the counter corresponding to the second special figure starting port 128. The latched value is stored in a built-in counter value storage register corresponding to the second special figure starting port 128. Similarly, when the counter circuit 316 receives a signal indicating that a ball has won at the general start port 124, the counter circuit 316 latches the value at the timing of the counter corresponding to the general start port 124, and the latched value. Is stored in a built-in counter value storage register corresponding to the normal start port 124.

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

<Sub control unit>
Next, the sub control unit 400 of the pachinko machine 100 will be described. The sub-control unit 400 includes a basic circuit 402 that controls the entire sub-control unit 400 mainly based on commands transmitted from the main control unit 300. The basic circuit 402 includes a CPU 404, a control program, ROM 406 for storing various data, RAM 408 for temporarily storing data, I / O 410 for controlling input / output of various devices, and counter timer 412 for measuring time and frequency It is installed.

The sub-control unit 500 is connected to a chance button detection circuit 380 that detects the pressing of the chance button 146 and outputs a signal.

<Discharge control unit, launch control unit, power supply management unit>
Next, the payout control unit 550, the launch control unit 600, and the power supply management unit 650 of the pachinko machine 100 will be described. The payout control unit 550 controls the payout device 552 mainly based on a signal such as a command transmitted from the main control unit 300, and the payout of the winning ball or the rental ball is completed based on a control signal output from the payout sensor 554. It is detected whether or not the card unit 654 is provided separately from the pachinko machine 100 via the interface unit 556.

  The firing control unit 600 determines the amount of operation of the launch handle 148 by the player, which is output from the control signal instructing permission or stop of launch output from the payout control unit 550, or the launch intensity output circuit provided in the operation handle 148. Based on the control signal instructing the corresponding launch intensity, the launch motor 602 that drives the launcher 138 and the launcher 140 is controlled, and the ball feeder 604 that supplies the 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 CPU 304, ROM (built-in ROM) 306, RAM (built-in RAM) 308, counter timer 312 (timer circuit 312a, counter circuit 312b), counter circuit (random number circuit) 316, I / O 310 (external bus). In addition to a control circuit 310a, a reset control circuit 310b with a built-in WDT 313, a parallel input port 310c, an address decoding circuit 310d), a clock circuit 340 and the like are provided.

  The clock circuit 340 divides the external clock EX (24 MHz clock in this example) input from the above-described crystal oscillator 314b (hereinafter sometimes referred to as the system crystal oscillator 314b) via the EX terminal to a predetermined frequency. This circuit divides the signal by a ratio (1/2 in this example) and supplies the divided system clock SCLK (12 MHz clock in this example) to the CPU core and internal circuits. Although the details will be described later, the random number circuit 316 is a random number clock RCK (in this example, 10 MHz) input from the above-mentioned crystal oscillator 314a (hereinafter sometimes referred to as a random number crystal oscillator 314a) via the RCK terminal. This is a circuit for generating a random value by counting a count value based on a clock. In the present 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.

  FIG. 7 is a circuit block diagram showing an example of wiring patterns of the random number crystal oscillator 314 a and the system crystal oscillator 314 b connected to the basic circuit 302.

  In this embodiment, the length of the signal line Ls connecting the basic circuit 302 and the system crystal oscillator 314b is set shorter than the length of the signal line Lr connecting the basic circuit 302 and the random number crystal oscillator 314a (Lr>). Ls). With such a configuration, the system crystal oscillator 314b can be disposed in the vicinity of the basic circuit 302, and the length of the signal line Ls connecting the basic circuit 302 and the system crystal oscillator 314b can be shortened. The signal of the external clock EX output from the system crystal oscillator 314b can be stably supplied to the clock circuit 340 of the basic circuit 302, and the system clock SCLK generated based on the signal of the external clock EX These signals can also be stably supplied to the CPU core and internal circuits.

  The length of the signal line connecting the supply source and the supply destination of the clock signal is generally set as short as possible so that no disturbance is applied to the clock signal. However, the basic circuit 302 and the random number crystal oscillator 314a are provided. The length of the signal line Lr to be connected is set to be long and the signal of the random number clock RCK passing through the signal line Lr is configured to be easily affected by the disturbance, so that the count value is based on the signal of the random number clock RCK. The random number circuit 316 that counts the random number circuit 316 can vary in the update timing of the count value, and the randomness value generated by the random number circuit 316 can be further improved in randomness.

  Further, by making the length of the signal line Ls connecting the basic circuit 302 and the system crystal oscillator 314b different from the length of the signal line Lr connecting the basic circuit 302 and the random number crystal oscillator 314a, the components near the basic circuit 302 are changed. The degree of freedom of arrangement can be increased.

<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. 8 is an internal configuration diagram of the random number circuit, and FIG. 9 is an internal configuration diagram of the frequency monitoring circuit included in the random number circuit.

  The random number circuit 316 includes four random number circuits CH1 to CH4. Since the internal configuration of the random number circuits CH2 to CH4 is the same as that of the random number circuit CH1, the illustration is omitted.

  The random number circuits CH1 to CH4 include a random number register 316b for storing the random number value fetched by the random number update circuit 316g, a random number latch flag register 316c for indicating that the random number value has been fetched by the random number register 316b, Random number interrupt control register 316d for controlling the interrupt and random number update circuit 316g monitor whether the random number value is normally updated or not, and outputs a random value abnormal signal when there is an abnormality in the update. A monitoring circuit 316e and an internal information register 316f that sets a random value abnormal signal state bit to 1 when a random value abnormal signal is input from the random number monitoring circuit 316e are configured. Note that the random number monitoring circuit 316e may be incorporated in the random number update circuit 316g, or may be provided in common in the random number circuits CH1 to CH4 (if provided in common, a flag is set so that CH1 to CH4 can be identified). It may be provided, or a flag may be provided in common).

  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 / non-use of the random number circuits CH1 to CH4, the selection of the initial value / random number sequence changing method, the update period 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.

  Further, the random number circuits CH1 to CH4 include a frequency monitoring circuit 316a. As shown in an enlarged view in FIG. 9, 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 random value abnormal signal status bit and the clock signal status bit of the internal information register at a predetermined timing. When the random value abnormal signal state bit is set to 1 (when there is an abnormality in updating the random value in the random number update circuit 316g), it is determined that some abnormality has occurred in the random number update circuit 316g, When the random value abnormal signal state bit is set to 0, it is determined that the random number update circuit 316g is normal.

  Further, 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). ) 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, with reference to FIG. 12, the winning acceptance process in the main controller timer interrupt process described above will be described. 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. A value extracted from the random value register of the circuit 316 is acquired as a special figure winning random value, or a value obtained by performing “predetermined processing” on the extracted value is acquired as a special figure winning random value. Further, the value extracted from the random number counter for generating the special figure random value described above is acquired as the special figure random number value, or the value obtained by performing “predetermined processing” on the extracted value is acquired as the special figure random number value, and stored in the RAM 308. A special figure winning random number value is stored in a random value storage area provided.

  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 A value extracted from the random value register of the circuit 316 is acquired as a special figure winning random value, or a value obtained by performing “predetermined processing” on the extracted value is acquired as a special figure winning random value. Further, the value extracted from the random number counter for generating the special figure random value described above is acquired as the special figure random number value, or the value obtained by performing “predetermined processing” on the extracted value is acquired as the special figure random number value, and stored in the RAM 308. A special figure winning random number value is stored in a random value storage area provided.

  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 the opening / closing control of the door member is repeated a predetermined number of times (for example, 15 rounds), Information indicating the effect standby period is set in the storage area of the effect standby time management timer provided in the RAM 308 in order to set to wait for a period during which an image for informing the player that the jackpot is to be ended is displayed. Further, 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, a 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, a 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. 16C is a flowchart showing the flow of the variation pattern selection process, and FIG. 16D 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).

<Package of basic circuit 302>
Next, a package in which the basic circuit 302 of the above-described main control unit 300 is mounted will be described in detail. FIG. 17A is an external perspective view of a package 680 on which the basic circuit 302 is mounted, and FIG. 17B is a side view showing the vicinity of the visually uneasy portion of the package 680.

  A plurality of terminals 682 are arranged on the both sides in the short direction of the package 680 along the longitudinal direction of the package 680. The package (microcomputer) 680 is provided with the terminals 682, and the micro terminals are provided by the terminals 682. A first region on the back surface of the computer 680 (for example, a space below the back surface), a second region on the surface of the substrate facing the back surface (for example, a space above the surface), and between the back surface and the surface A specific area that is at least one of the third areas in the space (for example, when the microcomputer is mounted on the substrate via the IC socket, includes the space near the front and back surfaces of the IC socket). By making the visually uneasy part 680a difficult to be provided and the terminal 682, it is more specific than the visually uneasy part 680a. It is configured to include a visual readily portion 680b to facilitate viewing of the band, a.

  Such a configuration makes it possible to visually recognize the other side (for example, the back side) of the package 680 from the one side (for example, the front side) through the easy-to-view part 680b. In some cases, it is possible to easily find a fraudulent act such as attaching a fraudulent circuit to a gap between substrates (or IC sockets), and to prevent the fraudulent act.

  In particular, in this example, the easy-to-view part 680b is provided on the side surface in the short direction, so that it is more difficult to see especially on the back side of the package 680 compared to the case where it is provided on the side surface in the longitudinal direction. It is possible to visually recognize the vicinity of the center of the back side that is easy, and there are cases where fraud can be prevented more reliably. Furthermore, since the easy-to-view part 680b is provided in the vicinity of the center part in the longitudinal direction, it is possible to visually recognize a wide range on the back side of the package 680 from various angles as compared with the case where it is provided in the vicinity of the end part in the longitudinal direction. In some cases, fraud can be prevented more reliably. Note that if the easy-to-view part is also provided on the side surface in the longitudinal direction, the visible range can be further expanded, and illegal acts may be prevented more reliably.

<Package modification>
Next, a modified example of the package 700 will be described. 18A is a plan view of the package 700 on which the basic circuit 302 is mounted, and FIG. 18B is an external perspective view showing only the terminals of the package 700 and the lower substrate.

  The package 700 includes a plate-like upper substrate 702 and a lower substrate 704, a basic circuit (CPU core) 302 disposed so as to be sandwiched between the upper substrate 702 and the lower substrate 704, and the basic circuit. A plurality of terminals (lead frames) 706 connected to each of the connection terminals 302 via bonding wires, and the plurality of terminals 706 are disposed along the longitudinal direction on both sides in the short direction. (Dual Inline Package). Each of the upper substrate 702 and the lower substrate 704 of the package 700 is configured by arranging easy-to-view parts 702a and 704a made of a transparent member and non-viewable parts 702b and 704b made of a non-transparent member alternately in the longitudinal direction. Has been. The easy-to-view part 702a on the upper substrate 702 and the easy-to-view part 704a on the lower substrate 704 are stacked at the same position in the longitudinal direction, and the non-viewable part 702b on the upper substrate 702 and the non-viewable part on the lower substrate 704 are stacked. 704b is laminated | stacked on the same position of a longitudinal direction.

  Such a configuration makes it possible to visually recognize the other side (for example, the back side) of the package 700 from the one side (for example, the front side) through the easy-to-view parts 702a and 704a. In some cases, it is possible to easily find a fraudulent act such as attaching a fraudulent circuit to the gap between 700 and the substrate (or IC socket), and to prevent the fraudulent act.

  Note that the easy-to-view parts 702a and 704a only need to be formed of a member that allows the back side of the package 700 to be visually recognized. For example, the whole may be formed of a translucent member, and at least a part of the member may be a transparent member. Or a semi-transparent member, and other parts may be formed of a non-transparent member. In addition, the non-viewable parts 702b and 704b may be formed of a member whose back side of the package 700 is invisible or difficult to see. For example, even if the whole is made of a semi-transparent member that is invisible or difficult to see. Good. Further, the easy-to-view parts 702a and 704a and the non-visible parts 702b and 704b are alternately arranged at the same position in the longitudinal direction, but for example, a package may be formed only by the easy-to-view parts 702a and 704a. The easy-to-view parts 702a and 704a and the non-viewable parts 702b and 704b may be alternately arranged in the short direction.

<Package Modification / Modification 1>
Next, a modified example of the package 700 will be described. FIG. 19A is an external perspective view showing a part of the lower substrate 714 (714a, 714b) of the package 710 according to the first modification. The lower substrate 714 of the package 710 according to the first modified example (not shown, but the upper substrate has the same configuration. The same applies to the following modified examples) includes an easily visible portion 714a made of a transparent member and a non-transparent member. However, the arrangement of the terminals 716 in the easy-to-view part 714a and the arrangement of terminals 716 in the non-viewable part 714b are the same as in the package 700. It is different.

  Specifically, in the easy-to-view part 714a, one terminal 716 is arranged with respect to the length L1 in the longitudinal direction of the easy-to-view part 714a, and in the non-viewable part 714b, in the longitudinal direction of the easy-to-view part 714a. Three terminals 716 are arranged at substantially equal intervals with respect to the length L1 (in this example, the same length as the length L1 in the longitudinal direction of the easy-to-view part 714a), and the terminals 716 in the non-viewable part 714b The number of terminals 716 (one in this example) in the easy-to-view part 714a is smaller than the number (three in this example).

  In other words, among the terminals 716 arranged in the easy-to-view part 714a and the terminals 716 arranged in the non-visible part 714b, the distance L2 between the terminal 716 closest to the easy-to-view part 714a and the non-visible The distance L3 between the plurality of terminals 716 arranged in the portion 714b is different, and the distance L2 is longer than the distance L3.

  With such a configuration, the number of terminals 716 is small (the number of members that hinder viewing) is small, and the other side of the package 710 can be reliably visually recognized through the easy-to-view part 714a, and visibility is high even when the number of terminals 716 is large. In some cases, a large number of terminals 716 can be arranged in the visually uneasy portion 714b that does not affect the visual field. In addition, if a signal line that is easily affected by noise from adjacent terminals is preferentially connected to the terminal 716 disposed in the easy-to-view part 714a having a low terminal density, while ensuring visibility, at the same time, noise or the like In some cases, it is possible to prevent malfunctions caused by the occurrence of a malfunction.

<Package Modification / Modification 2>
FIG. 19B is an external perspective view showing a part of the lower substrate 724 (724a, 724b) of the package 720 according to the second modification. The substrate of the package 720 according to the second modification is the same as the package 700 in that the easy-to-view parts 724a made of a transparent member and the non-visible parts 724b made of a non-transparent member are alternately arranged in the longitudinal direction. However, a plurality (three in this example) of terminals 726 are arranged in the visually unrecognizable part 724b, whereas no terminal 726 is arranged in the easily visible part 724a.

  With such a configuration, the visibility in the easy-to-view part 724a can be further ensured, and the other side of the package 720 can be surely visually recognized. In addition, a plurality of signal lines that are easily affected by noise from adjacent terminals are connected to the terminal 726 of the non-viewable part 724b on one side of the easy-to-view part 724a (for example, the right side of FIG. If it is connected to the terminal 726 of the non-viewable portion 724b on the other side (for example, the left side of the figure) at a distance, it is possible to prevent malfunction caused by noise or the like while ensuring visibility. Sometimes it can be prevented.

<Modification of Package / Modification 3>
FIG. 19C is an external perspective view illustrating a part of the lower substrate 732 (732a, 732b) of the package 730 according to the third modification. In the substrate of the package 730 according to the third modification, a cube-shaped easy-to-view part 732a made of a transparent member is formed on a part of the non-visible part 732b made of a non-transparent member. A plurality (three in this example) of terminals 736 are arranged, but no terminal 736 is arranged in the easy-to-view part 732a.

  With such a configuration, the cost of the substrate of the package 730 can be reduced as compared with the case where the easy-to-view parts and the non-viewable parts are alternately arranged in the longitudinal direction, and one side of the package 730 through the easy-to-view part 732a. The other side can be visually recognized.

  The easy-to-view parts 732a may be formed on both sides in the short direction of the substrate of the package 730, or may be formed only on one side in the short direction, but if formed on both sides, the visibility is further improved. May be possible. Further, the number of easy-to-view parts 732a may be one or plural, but if a plurality of easy-to-view parts 732a are formed, the visibility may be further improved.

<Package Modification / Modification 4>
FIG. 19D is an external perspective view showing a part of the lower substrate 742 (742a, 742b) of the package 740 according to the fourth modification. In the substrate of the package 740 according to the modification 4, a rectangular notch 742c that is recessed inward is formed in a part of the visually uneasy part 742b made of a non-transparent member, and the notch 742c is A plurality (three in this example) of terminals 746 are arranged in the part not formed, but no terminal 746 is arranged in the notch 742c.

  With such a configuration, the cost of the substrate of the package 740 can be reduced as compared with the case where the easy-to-view portion and the non-visible portion are configured as separate members, and the other side from the one side of the package 740 through the notch 742c. The side can be visually recognized.

  Note that the notches 742c may be formed on both sides of the substrate of the package 740 in the short direction, or may be formed only on one side in the short direction, but if formed on both sides, the visibility is further improved. May be possible. In addition, the number of the notched portions 742c may be one or plural, but if a plurality of the notched portions 742c are formed, the visibility may be further improved.

  Further, the notch 742c is formed in the package 740, so that the strength of the package 740 is reduced. For example, when the package 740 mounted on a substrate or an IC socket is removed, the package 740 is easily damaged (broken). However, in the package 740 according to the modified example 4, the package 740 may be illegally removed and crafted by illegally removing the package 740 by reducing the strength of the package 740 and making it difficult to remove.

<Modified example of IC socket / Modified example 1>
Next, a modified example of the IC socket will be described. FIG. 27A is an external perspective view of an IC socket 860 according to the first modification, and FIG. 27B is an external perspective view showing a state where a package 740 is mounted on the IC socket 860.

  The socket 860 according to Modification 1 is different in that the opening 852a of the socket 850 described above is not provided. Even when the package 740 is mounted on such a socket 860 that does not include the opening 852a, the package 740 includes the notch 742c, so that the other side of the package 740 can be visually recognized through the notch 742c.

  In particular, if the terminal 746 of the package 740 has a length sufficient to float and hold the package 740 from the IC socket 860 when the package 740 is mounted on the IC socket 860, In addition to being able to visually recognize the lower space of the package 740 from the side of the terminal 746, the visibility through the notch 742c may be further improved. On the other hand, the space formed between the package 740 and the IC socket 860 does not have a height high enough to allow electronic components to be placed. Making it difficult.

<Modified example of IC socket / Modified example 2>
Next, a modified example of the IC socket will be described. FIG. 28A is an external perspective view of an IC socket 870 according to the second modification, and FIG. 28B is a plan view of a substrate on which the socket terminal of the IC socket 870 is mounted.

  The IC socket 870 according to the modification 2 is different from the above-described IC sockets 850 and 860 in the arrangement mode of the socket terminal 874 with respect to the base 872. Specifically, in the IC socket 870, the connecting portions 872b into which the terminals of the package are inserted are linearly arranged at substantially equal intervals over the entire length direction, but project from each connecting portion 872b. The formed socket terminals 874 are arranged in a staggered manner over the entire longitudinal direction. Further, as shown in FIG. 4B, lands 878a are arranged and formed in a staggered manner on the substrate 878 on which the IC socket 870 is mounted in accordance with the arrangement mode of the socket terminals 874 of the IC socket 870.

<Connect part and socket terminal>
Fig.29 (a) is the figure which showed the cross section along the AA line in Fig.28 (a) typically, FIG.29 (b) follows the BB line in Fig.28 (a). FIG. As shown in FIG. 29A, among the plurality of socket terminals 874, the socket terminal 874 protruding inward in the short direction of the IC socket 870 is a predetermined distance inward in the short direction from the axis La of the connecting portion 872b. The shaft center Lb is located at a position separated by L8, and is disposed at a position separated by a predetermined distance L9 from the outer end surface in the short direction of the IC socket 870. On the other hand, as shown in FIG. 29B, of the plurality of socket terminals 874, the socket terminal 874 protruding outward in the short direction of the IC socket 870 is outward in the short direction from the axial center La of the connecting portion 872b. The shaft center Lc is located at a position separated by a predetermined distance L8, and is disposed at a position separated by a predetermined distance L10 (L10 <L9) from the lateral direction outer end surface of the IC socket 870.

  In this example, the length of the connecting portion 872b and the length of the socket terminal 874 are the same for the entire IC socket 870. That is, when the IC socket 870 is mounted on the substrate and the package is mounted on the IC socket 870, the distance between the contact between the package terminal and the connector portion 872b and the contact between the socket terminal 874 and the contact of the substrate is The entire IC socket 870 is configured to have substantially the same length.

<Modification example of connection part and socket terminal / Modification example 1>
FIGS. 30A and 30B are views schematically showing cross sections of the connecting portion and the socket terminal according to the first modification, and are views corresponding to FIGS. 29A and 29B, respectively. There are two types of connect portions according to the first modification, namely, a first connect portion 880 shown in FIG. 30A and a second connect portion 882 shown in FIG. Although illustration is omitted, in this example, the first connect portion 880 and the second connect portion 882 into which the terminals of the package are inserted are linearly arranged at substantially equal intervals over the entire longitudinal direction of the IC socket. On the other hand, the socket terminals 884 that protrude from the first connection portion 880 and the second connection portion 882 are arranged in a staggered manner over the entire longitudinal direction of the IC socket.

  The first connecting portion 880 has a linear shape extending straight from the front surface to the back surface of the IC socket along the axis Ld. The second connecting portion 882 includes a first straight portion extending straight from the front surface to the back surface of the IC socket along the axis Ld, and a bend extending obliquely toward the back surface using the first straight portion as a base end. And a second straight portion extending straight to the back surface of the IC socket along an axis Le different from the axis Ld with the bent portion as a base end. On the other hand, the socket terminals 884 all have the same length, and the socket terminal 884 connected to the first connector portion 880 is based on the first connector portion 880 on the same axis Ld as the first connector portion 880. A socket terminal 884 extending as an end and connected to the second connector portion 882 is based on the second straight portion of the second connector portion 882 on the same axis Le as the second straight portion of the second connector portion 882. It is extended and formed as an end.

  Therefore, in this example, the total length L11 of the first connection portion 880 and the length of the socket terminal 884 is greater than the total length L12 (L12> L11) of the second connection portion 882 and the length of the socket terminal 884. Is also shorter. That is, when an IC socket having such a configuration is mounted on a substrate and the package is mounted on the IC socket, two terminals, a contact between the package terminal and the first connector portion 880, and a contact between the socket terminal 884 and the substrate, are provided. The distance between the contacts is configured to be shorter than the distance between the contact between the package terminal and the second connector portion 882 and the contact between the socket terminal 884 and the substrate contact.

<Modified example of connection part and socket terminal / Modified example 2>
FIGS. 31A to 31D are diagrams schematically showing a cross section of the connection portion and the socket terminal according to the second modification. The first connect portion 892 and the second connect portion 893 shown in FIGS. 4A and 4B are a straight portion extending straight from the front surface to the back surface of the IC socket, and slanting to the back surface with the straight portion serving as a base end. The first connecting portion 892 shown in FIG. 1A and the second connecting portion 893 shown in FIG. 2B are opposite in bending direction. Although illustration is omitted, in this example, the straight portions of the first connect portion 892 and the second connect portion 893 into which the terminals of the package are inserted are substantially equidistant over the entire longitudinal direction of the IC socket. In contrast to the linear arrangement, the socket terminals 894 that protrude from the bent portions of the first connect portion 892 and the second connect portion 893 are formed over the entire longitudinal direction of the IC socket. Arranged in a staggered pattern.

  On the other hand, the connecting portion 895 shown in FIGS. 3C and 3D has a linear shape extending straight from the front surface to the back surface of the IC socket. Further, the first socket terminal 896 and the second socket terminal 897 are formed by a bent portion extending obliquely with the connecting portion 895 as a base end, and a straight portion extending straight in the thickness direction of the IC socket with the bent portion as a base end. The first socket terminal 896 shown in FIG. 1C and the second socket terminal 897 shown in FIG. Although illustration is omitted, in this example, the connecting portion 895 into which the terminal of the package is inserted is linearly arranged at substantially equal intervals over the entire longitudinal direction of the IC socket. The 1 socket terminal 896 and the 2nd socket terminal 897 are arrange | positioned at zigzag form over the longitudinal direction whole region of IC socket.

<Modified example of IC socket / Modified example 3>
FIG. 32A is an external perspective view of an IC socket 900 according to the third modification. In the above-described IC socket 850, the opening is formed at a position corresponding to the notch 742c of the package 740 to be mounted. However, as in this example, the opening is formed at a position corresponding to the notch 742c of the package 740 to be mounted. A reinforcing member 900a that connects both sides of the IC socket 900 may be provided. Further, in the above-described IC socket 850, the connection portion and the socket terminal are not arranged at the position corresponding to the notch portion 742c of the package 740. However, as in this example, the notch portion 742c of the package 740 is provided with the notch portion 742c. You may arrange | position the connection part 900b and the socket terminal 900c in the corresponding position. With such a configuration, it may be possible to increase the strength of the IC socket or increase the number of socket terminals while ensuring visibility from one side of the package to the other. Further, by arranging the connecting portion 900b and the socket terminal 900c, it becomes difficult to insert and attach an electronic component or the like between the package 740 and the IC socket 900, so that illegal acts may be prevented in advance. .

<Modified example of IC socket / Modified example 4>
FIG. 32B is an external perspective view of an IC socket 910 according to the fourth modification. As in this example, a recess 910a that matches the shape and size of the notch 742c may be formed at a position corresponding to the notch 742c of the package 740 to be mounted. With such a configuration, there is a case where not only the notch portion of the package but also the other side of the package can be visually recognized through the recess 910a of the IC socket 910, and visibility can be improved.

<Modified example of IC socket / Modified example 5>
FIG. 32C is an external perspective view of an IC socket 920 according to the fifth modification. As shown in this example, a convex shape that matches the shape and size of the notch portion 742c (for example, is formed of a transparent member in a shape that fits into the notch portion 742c) at a position corresponding to the notch portion 742c of the package 740. The part 920a may be formed. With such a configuration, it may be possible to prevent unauthorized equipment from being installed on the back of the package by preventing the convex portion 920a from creating a gap between the package, If the convex portion 920a is formed of a transparent member or a semi-transparent member, the other side of the package can be visually recognized through the convex portion 920a, and it may be easy to find that an unauthorized device or the like has been installed. The shape of the IC package is not limited to the shape matched to the shape of the package as shown in FIGS. 1A to 1C. For example, the shape matched to the shape of the substrate on which the IC package is mounted ( For example, when the substrate includes a convex portion, an IC socket including a concave portion having a shape complementary to the convex portion may be used.

  FIGS. 33A and 33B are external perspective views showing an example in which an IC socket is mounted on a substrate. In the example shown in FIG. 6A, the thickness of the IC socket 930 is made thinner than the thickness of other electronic components mounted on the substrate 932. With such a configuration, even when the package is mounted on the IC socket 930, it is possible to obscure the package with other electronic components and obscure the existence of the package. There is. In addition, since the electronic parts are not arranged in the short direction of the IC socket in which the above-described easy-to-view part and the notch part are arranged, the IC is provided via the easy-to-view part and the notch part. In some cases, the back side of the package mounted on the socket can be reliably seen.

  Further, in the example shown in FIG. 5B, the thickness of the IC socket 940 is made larger than the thickness of the plurality of electronic components 944 mounted on the substrate 942 on one side in the longitudinal direction of the IC socket 940. With such a configuration, when the IC socket 940 is observed from one side in the longitudinal direction of the IC socket 940, the presence of the IC socket 940 can be easily confirmed. There are cases where it can be increased. In addition, since the heat of the package is easily released to the outside of the substrate 942 as compared with the example of FIG. In this example, the electronic component 944 is disposed on one side in the longitudinal direction of the IC socket 940, but may be on both sides in the longitudinal direction or in a direction other than the longitudinal direction.

  Further, it is preferable that no electronic component is disposed on the extension of the IC socket 940 in the longitudinal direction of the IC socket 940. With such a configuration, the back side of the package mounted on the IC socket may be visible from the longitudinal direction of the IC socket.

  Further, as shown in FIG. 6C, when an upper case 953 made of a transparent member covering the surface of the substrate 950 and a lower case 954 covering the back surface of the substrate 950 are provided, the upper case 953 is mounted on the substrate 950. A recessed portion 953 a that is recessed toward the IC socket 951 or the package 952 may be formed at a position where the IC socket 951 or the package 952 is disposed. With such a structure, even when the substrate 950 is protected by the upper case 953, the back side of the IC socket 951 or the package 952 may be reliably visible.

<Wiring pattern>
Next, the wiring pattern of the substrate on which the above IC socket is mounted will be described. FIG. 34A is a diagram showing an example of lands on which an IC socket is mounted, and signal lines connecting these lands to the random number crystal oscillator 314a and the system crystal oscillator 314b. These are the elements on larger scale near the land. FIG. 35 is a view for explaining the outer edge of the IC socket.

  In this example, a plurality of lands 1004a and 1004b (only part of which are shown) on which an IC socket is mounted (to which a socket terminal of the IC socket is connected) are formed on a substrate 1002, and a mounting portion of the IC socket is formed. A random crystal oscillator 314a and a system crystal oscillator 314b are mounted at a predetermined distance from each other. The lands 1004a and 1004b are arranged corresponding to the socket terminals of the IC socket mounted on the substrate 1002. In this example, the outer edge line OL representing the outer edge of the IC socket when the IC socket is mounted on the substrate 1002 is used. There are two types: a circular outer land 1004a centered at a position separated from the outer edge line OL by a predetermined distance L21 and a circular inner land 1004b centered at a position separated from the outer edge line OL by a predetermined distance L22 (L22> L21). is there.

  Here, the “outer edge of the IC socket” means a virtual plane VP including a surface 1001a on the outer side in the short direction of the IC socket 1001 in a state of being mounted on the substrate 1002, as shown in FIG. A line formed by intersecting the surface of the substrate 1002 with the surface of the substrate 1002 is the above-described outer edge line OL.

  The system crystal oscillator 314b is connected to the outer land 1004a via the first signal line 1006, and the random number crystal oscillator 314a is connected to the inner land 1004b via the second signal line 1008. The length of the first signal line 1006 is determined by the distance L20 from the external clock EX terminal of the system crystal oscillator 314b to the outer edge line OL, and the outer land 1004a from the outer edge line OL (in this example, via the connecting portion of the IC socket). The value is obtained by adding the distance L21 to the center of the land connected to the EX terminal of the package, and the length of the second signal line 1008 is the distance from the random number clock RCK terminal of the random number crystal oscillator 314a to the outer edge line OL. This is a numerical value obtained by adding L20 and the distance L22 from the outer edge line OL to the center of the inner land 1004b (in this example, the land connected to the RCK terminal of the package through the connection portion of the IC socket). That is, in this example, the length (L20 + L22) of the second signal line 1008 is longer than the length (L20 + L21) of the first signal line 1006. Further, in this example, the distance from the inner land 1004b to the package RCK terminal is closer than the distance from the outer land 1004a to the package EX terminal, that is, from the inner land 1004b to the package RCK terminal. The input random number clock signal RCK is set so as to be easily affected by noise generated from the package.

  FIG. 36 is a side view of the substrate 1002 as viewed from the side. The first signal line 1006 connects the system crystal oscillator 314b and the IC socket straight along the flat substrate surface without any difference in height, and the second signal line 1008 is a random number along the flat substrate surface. The crystal oscillator 314a for use and the IC socket are connected straight without any difference in height.

  With this configuration, the system crystal oscillator 314b can be disposed in the vicinity of the package (basic circuit 302), and the length of the first signal line 1006 connecting the package and the system crystal oscillator 314b can be shortened. Therefore, the external clock EX signal output from the system crystal oscillator 314b can be stably supplied to the clock circuit 340 of the basic circuit 302, and is generated based on the external clock EX signal. The signal of the system clock SCLK can also be stably supplied to the CPU core and internal circuits.

  The length of the signal line connecting the supply source and the supply destination of the clock signal is generally set as short as possible so that no disturbance is applied to the clock signal. However, the basic circuit 302 and the random number crystal oscillator 314a are provided. The length of the second signal line 1008 to be connected is deliberately set longer, and the signal of the random number clock RCK passing through the second signal line 1008 is configured to be easily affected by the disturbance. Based on the count value update timing of the random number circuit 316 that counts the count value, the randomness value generated by the random number circuit 316 can be further improved in randomness.

  In particular, the portion of the first signal line 1006 that is not hidden by the IC socket (the signal line from the external clock EX terminal of the system crystal oscillator 314b to the outer edge line OL) and the second signal line 1008 that is hidden by the IC socket. Since no part (the signal line from the random number clock RCK terminal of the random number crystal oscillator 314a to the outer edge line OL) is set to the same length, the length of the second signal line 1008 is set to be longer at first glance. I can't figure out what is being done. For this reason, there is a possibility that a fraudulent person may increase the possibility of fraud. However, since the abnormality of the signal of the random number clock RCK can be detected, the fraudulent act can be reliably detected.

<Modification Example of Wiring Pattern / Modification Example 1>
FIG. 37 is a diagram illustrating a wiring pattern according to the first modification. In this example, an outer land 1014a and an inner land 1014b (only part of which are shown) on which an IC socket is mounted are formed on a substrate 1012, and a system crystal oscillator 314b (also serving as a random number crystal oscillator 314a) is provided. Has been implemented.

  The system crystal oscillator 314b is connected to the outer land 1014a via the first signal line 1016 and is connected to the inner land 1014b via the second signal line 1018. The length of the first signal line 1016 is determined by the distance L30 from the external clock EX terminal of the system crystal oscillator 314b to the outer edge line OL, and the outer land line OL to the outer land 1014a (in this example, via the connection portion of the IC socket). A value obtained by adding a distance L31 to the center of the land connected to the RCK terminal of the package, and the length of the second signal line 1018 is a distance L32 from the external clock EX terminal of the system crystal oscillator 314b to the outer edge line OL. (L32> L30) and a distance L33 (L33> L31) from the outer edge line OL to the center of the inner land 1014b (in this example, the land connected to the RCK terminal of the package via the connecting portion of the IC socket) It becomes the numerical value. That is, in this example, the length (L32 + L33) of the second signal line 1018 is longer than the length (L30 + L31) of the first signal line 1016.

  With this configuration, the system crystal oscillator 314b can be disposed in the vicinity of the package (basic circuit 302), and the length of the first signal line 1016 connecting the package and the system crystal oscillator 314b can be shortened. Therefore, the external clock EX signal output from the system crystal oscillator 314b can be stably supplied to the clock circuit 340 of the basic circuit 302, and is generated based on the external clock EX signal. The signal of the system clock SCLK can also be stably supplied to the CPU core and internal circuits.

  In general, the length of the signal line connecting the supply source and the supply destination of the clock signal is set as short as possible so that no disturbance is applied to the clock signal, but the length of the second signal line 1018 is deliberately set. The random number circuit 316 that counts the count value based on the signal of the random number clock RCK by setting the signal to be longer and configured so that the signal of the random number clock RCK passing through the second signal line 1018 is easily affected by the disturbance. Thus, the randomness of the random number generated by the random number circuit 316 can be further improved.

  In some cases, the wiring pattern can be simplified by sharing a part of the first signal line 1016 and the second signal line 1018.

<Modifications of wiring pattern / Modifications 2, 3>
FIG. 38A is a diagram illustrating a wiring pattern according to the second modification. This example is substantially the same as the wiring pattern shown in FIG. 34A, but includes an outer land 1004a to which the system crystal oscillator 314b is connected and an inner land 1004b to which the random number crystal oscillator 314a is connected. Two outer lands 1004a are arranged between them. One outer land 1004a is connected to a first power supply terminal (for example, the above-described positive power supply terminal VDD1) of the package, and the other outer land 1004a is connected to a second power supply terminal (for example, the above-described backup power supply). The connection is different from the terminal VBB).

  On the other hand, FIG. 5B is a diagram showing a wiring pattern according to the third modification. This example is similar to the wiring pattern shown in FIG. 6A, but the power line 1033 from the outer land 1004a connected to the first power terminal of the package is connected to the substrate 1032 through the through hole. A power supply line 1034 from the outer land 1004a connected to the second power supply terminal of the package is wired on the back surface of the substrate 1032 through the vicinity of the random value crystal oscillator 314a.

  With such a configuration, the signal of the external clock EX passing through the first signal line 1006 can be hardly affected by the power supply line, and the signal of the external clock EX output from the system crystal oscillator 314b can be stably output. In addition to being able to be supplied to the clock circuit 340 of the basic circuit 302, the system clock SCLK signal generated based on this external clock EX signal can also be stably supplied to the CPU core and internal circuits. .

  Further, by arranging the power supply line 1034 in the vicinity of the second signal line 1008 so that the signal of the random number clock RCK passing through the second signal line 1008 is easily affected by the disturbance, the signal of the random number clock RCK Thus, the random number circuit 316 that counts the count value can be varied in the update timing of the count value, and the randomness of the random value generated by the random number circuit 316 can be further improved.

<Modification Example of Wiring Pattern / Modification Example 4>
FIG. 39 is a diagram illustrating a wiring pattern according to the fourth modification. In this example, the land 1044a disposed above the land 1044b to which the system crystal oscillator 314b is connected is connected to the ground terminal of the package (for example, the above-described ground potential terminal VSS1), and the system crystal oscillator A land 1044c disposed below the land 1044b to which the 314b is connected is connected to a first power supply terminal (for example, the above-described positive power supply terminal VDD1) of the package. A land 1044d disposed above the land 1044e to which the random number crystal oscillator 314a is connected is connected to the second power supply terminal of the package (for example, the above-described backup power supply terminal VBB), and is used for the random number. A land 1044f disposed below the land 1044e to which the crystal oscillator 314a is connected is connected to a control signal line (for example, a chip select terminal) of the package.

  Thus, by arranging a line (power supply line, ground line) with little signal change in the vicinity of the first signal line 1006, the signal of the external clock EX passing through the first signal line 1006 is less affected. The external clock EX signal output from the system crystal oscillator 314b can be stably supplied to the clock circuit 340 of the basic circuit 302, and the system is generated based on the external clock EX signal. The signal of the clock SCLK can also be stably supplied to the CPU core and internal circuits.

  Further, by arranging a line (control signal line) with a large signal change in the vicinity of the second signal line 1008, the signal of the random number clock RCK passing through the second signal line 1008 is easily affected by disturbance. By doing so, the count value update timing of the random number circuit 316 that counts the count value based on the signal of the random number clock RCK can be varied, and the randomness of the random number value generated by the random number circuit 316 can be further enhanced. .

<Modification of wiring pattern / Modification 5>
FIG. 40A is a diagram illustrating a wiring pattern according to the fifth modification. In this example, three lands 1040a, 1040b, and 1040c are disposed at a position separated from the outer edge line OL on the substrate by a predetermined distance L41, the land 1040a is connected to the ground line 1042, and the land 1040b is connected to the system crystal oscillator. The land 1040 c is connected to the system clock line 1044, and the power line 1046 is connected. Further, a distance W1 between the outer edge of the land 1040a to which the ground line 1042 is connected and the outer edge of the land 1040b to which the system clock line 1044 is connected, the outer edge of the land 1040b to which the system clock line 1044 is connected, The distance W1 between the outer edge of the land 1040c to which the line 1046 is connected is the same distance.

  On the other hand, in the example shown in FIG. 5B, the land 1040a to which the ground line 1042 is connected and the land to which the power line 1046 is connected are separated from the outer edge line OL on the substrate by a predetermined distance L41. The land 1040b to which the system clock line 1044 is connected is disposed at a position separated from the outer edge line OL on the substrate by a predetermined distance L42 (L42> L41). Further, by disposing the land 1040b at a position farther from the outer edge line OL than the lands 1040a and 1040c, the distance W2 between the outer edge of the land 1040a to which the ground line 1042 is connected and the outer edge of the system clock line 1044 is Both the distance W2 between the outer edge of the system clock line 1044 and the outer edge of the land 1040c to which the power supply line is connected are longer than the distance W1 shown in FIG.

  Further, in the example shown in FIG. 7C, a land 1040a to which the ground line 1042 is connected and a land 1040c to which the power line 1046 is connected are arranged at a position separated from the outer edge line OL on the substrate by a predetermined distance L42. The land 1040b to which the system clock line 1044 is connected is disposed at a position separated from the outer edge line OL on the substrate by a predetermined distance L41 (L41 <L42). Further, by disposing the lands 1040a and 1040c at positions farther from the outer edge line OL than the land 1040b, the distance W2 between the outer edge of the ground line 1042 and the outer edge of the land 1040b to which the system clock line 1044 is connected is Both the distance W2 between the land 1040b to which the system clock line 1044 is connected and the outer edge of the power supply line 1046 are made longer than the distance La shown in FIG.

  According to the configuration shown in FIGS. 7B and 7C, the system clock line 1044 can be disposed at a position away from the ground line 1042 and the power supply line 1046 by a distance corresponding to the swelling of the land. The signal of the external clock EX passing through the clock line 1044 can be hardly affected, and the signal of the external clock EX output from the system crystal oscillator 314b is stably supplied to the clock circuit 340 of the basic circuit 302. In addition, the signal of the system clock SCLK generated based on the signal of the external clock EX can be stably supplied to the CPU core and internal circuits. In this example, the distance between the outer edge of the ground line 1042 and the outer edge of the land 1040b to which the system clock line 1044 is connected, the land 1040b to which the system clock line 1044 is connected, and the outer edge of the power supply line 1046 However, for example, one may be longer than the other.

<Modification Example of Wiring Pattern / Modification Example 6>
FIG. 41 is a diagram illustrating a wiring pattern according to the sixth modification. In this example, two lands 1050a and 1050b are arranged at a position away from the outer edge line OL on the substrate by a predetermined distance L51, and at a position away from the outer edge line OL on the board by a predetermined distance L52 (L52> L51). One land 1050c is arranged. The land 1050a is connected to the external clock EX terminal of the system crystal oscillator 314b, and the signal line connecting the two is not bent but is linear. On the other hand, the land 1050c is connected to the random number clock RCK terminal of the random number crystal oscillator 314b, and the signal line connecting both is bent halfway.

  With such a configuration, the system crystal oscillator 314b can be disposed in the vicinity of the package (basic circuit 302), and the length of the first signal line 1052 connecting the package and the system crystal oscillator 314b can be shortened. Therefore, the external clock EX signal output from the system crystal oscillator 314b can be stably supplied to the clock circuit 340 of the basic circuit 302, and is generated based on the external clock EX signal. The signal of the system clock SCLK can also be stably supplied to the CPU core and internal circuits.

  The length of the signal line connecting the supply source and the supply destination of the clock signal is generally set as short as possible so that no disturbance is applied to the clock signal. However, the basic circuit 302 and the random number crystal oscillator 314a are provided. The length of the second signal line 1054 to be connected is set to be long, and the signal of the random number clock RCK passing through the second signal line 1054 is configured to be easily affected by the disturbance, whereby the signal of the random number clock RCK is changed. Based on the count value update timing of the random number circuit 316 that counts the count value, the randomness value generated by the random number circuit 316 can be further improved in randomness.

<Board>
FIG. 42 is a plan view of a substrate on which the above-described IC socket is mounted. The substrate 1050 shown in the figure includes four rectangular IC socket mounting portions 1054 having a plurality of lands 1052 for mounting socket terminals of the IC socket, and a ground region 1056 around the IC socket mounting portion 1054. It is said. Of the plurality of lands 1052, two lands 1052a connected to the ground terminal of the package are in direct communication with the ground region 1056 without passing through signal lines or the like. Note that the substrate according to the present embodiment may be a component surface or a solder surface.

  With such a configuration, there are cases where the number of ground lines connecting the substrate and the land can be reduced as compared to the conventional case, and in addition, when it is desired to obtain the ground potential by changing the circuit, the ground potential can be easily obtained. There are cases where it can be increased.

<Variation of substrate / Variation 1>
FIG. 43 is a plan view of a substrate according to the first modification. The substrate 1060 shown in the figure includes four IC socket mounting portions 1064 having a plurality of lands 1062 for mounting the socket terminals of the IC socket, and the other side of the IC socket mounted on the substrate 1060 is changed from the other side. A power supply region 1068 is arranged so as to straddle it. Of the plurality of lands 1062, two lands 1062 a used as power supply terminals of the package are directly connected to the power supply region 1068 without passing through signal lines or the like.

  With such a configuration, the power line connecting the board and the land may be reduced as compared to the conventional case, and in addition, when it is desired to take a power source by changing the circuit, the power source can be easily taken and the convenience is improved. May be possible.

<Variation of substrate / Variation 2>
FIG. 44 is a plan view of a substrate according to the second modification. The substrate 1070 shown in the figure includes four rectangular IC socket mounting portions 1074 having a plurality of lands 1072 for mounting socket terminals of IC sockets, and each of these IC socket mounting portions 1074 is provided. A plurality (four in this example) of lands 1072 are arranged in a staggered manner. In this example, among the lands 1072, only lands corresponding to socket terminals arranged outside the IC socket are connected to electronic components mounted on the substrate 1070, and the lands arranged inside are It is unused without being connected to electronic parts. In this example, there are four mounting portions in which the lands are arranged in a staggered pattern. However, the lands may be arranged in a staggered pattern in one, a plurality, or all of the four mounting units. Also, the number of mounting parts is not limited to four.

  With such a configuration, a predetermined distance can be provided between adjacent signal lines, the influence of noise and the like caused by other signal lines can be reduced, and circuit design can be facilitated.

<Modification Example of Substrate / Modification Example 3>
FIG. 45 is a plan view of a substrate according to the third modification. The substrate 1080 shown in the figure includes a plurality (16 in this example) of lands 1082 for mounting socket terminals of IC sockets, and these lands 1082 are arranged in a staggered manner. Further, in this example, of the plurality of lands 1082, only the lands corresponding to the socket terminals arranged outside the IC socket are connected to electronic components mounted on the substrate 1080, and the lands arranged inside are It is unused without being connected to electronic parts. Further, in this example, a region excluding a plurality of lands 1082 and wirings for electronic components or the like among all the regions of the substrate 1080 is a ground region 1084.

  With such a configuration, there are cases where the number of ground lines connecting the substrate and the land can be reduced as compared to the conventional case, and in addition, when it is desired to obtain the ground potential by changing the circuit, the ground potential can be easily obtained. There are cases where it can be increased. In addition, a predetermined distance can be provided between adjacent signal lines, and the influence of noise and the like caused by other signal lines can be reduced, and circuit design can be facilitated.

As described above, the pachinko machine 100 according to the present embodiment has the first clock generating means (for example, the system crystal oscillator 314b shown in FIG. 41) that generates the external clock and the second clock that generates the random number clock. Clock generation means (for example, a random number crystal oscillator 314a shown in FIG. 41), system clock generation means capable of generating at least a system clock from the external clock, a random number circuit to which the random number clock is input, and the system A gaming machine comprising: a CPU capable of executing at least a game control process based on a clock; and an IC socket (for example, an IC socket shown in FIG. 25) mounted on a control board, wherein the CPU, the system clock The generating means and the random number circuit are built in a microprocessor, and the microphone The processor is connected to the IC socket, and the game control process includes at least a process using a random number value generated by the random number circuit, and the first clock generation means and the first clock generation means Both of the second clock generation means are not included in the microprocessor, the IC socket is provided with at least an external clock terminal and a random number clock terminal, and the external clock terminal is the external clock terminal. The random number clock terminal is a terminal to which the random number clock is input, and the first signal line (for example, from the external clock terminal to the first clock generation means) 41, and the second clock generation from the random number clock terminal. The stages are connected by a second signal line (for example, the second signal line 1054 shown in FIG. 41), and the length of the second signal line is longer than the length of the first signal line. The microprocessor is housed in a DIP type package (for example, a package 680 shown in FIG. 17) in which a plurality of terminals are provided on each of the first and second side surfaces, and the first side surface includes the first side surface and the second side surface. The package has a first portion (for example, a visual non-easy portion 680a shown in FIG. 17) in which two terminals are provided with a first gap therebetween. And the package has a second portion (for example, the easy-to-view part 680b shown in FIG. 17) in which two terminals are provided with a second gap, and the second gap is A gap wider than the first gap, The gaming machine is characterized in that at least the second part is disposed on at least one of the first and second side surfaces of the package.
According to the pachinko machine 100 according to the present embodiment, the length of the signal line connecting the supply source and the supply destination of the clock signal is generally set as short as possible so that no disturbance is applied to the clock signal. By setting the length of the second signal line to be longer than the length of the first signal line, and configuring the random number clock signal passing through the second signal line to be easily affected by disturbance, In a game control process in which a lottery for a game is performed based on a random number clock signal, the random number value update timing can be varied, and the randomness of the random number value can be improved as compared with the conventional technique. For this reason, it is possible to prevent an illegal act aiming at the timing of the lottery. In addition, a specific region of the package can be viewed from various angles through the second part. For this reason, it is possible to easily find a fraudulent act such as attaching a fraudulent circuit to the back side of the package or the gap between the package and the substrate (or IC socket), and to prevent the fraudulent act. In particular, the conventional DIP type package has a plurality of terminals provided on both side surfaces with short gaps, so that the back side of the package can be visually recognized unless all of the packages including the CPU core and bonding wires are transparent. Although there is a risk that an illegal circuit or the like may be retrofitted on the back side of the package, according to the present invention, the first region on the back surface of the package, the second region on the surface of the substrate facing the back surface, Or the 3rd area | region in the space between a back surface and a surface can be confirmed through a 2nd site | part, and an illegal act may be prevented more reliably. In addition, by having the second part, it is possible to arrange a plurality of terminals that are susceptible to the noise of adjacent terminals with a second gap wider than the first gap. In some cases, it is possible to prevent malfunction caused by noise or the like at the same time while ensuring the reliability.
The microprocessor further includes a clock signal monitoring unit that determines that the random number clock has become abnormal when the frequency of the random number clock is lower than the frequency of the clock obtained based on the system clock. May be included.
Since the IC socket obstructs the visibility of part of the first signal line and part of the second signal line, the length of the second signal line is longer than the length of the first signal line at first glance. It is difficult to grasp that is set. For this reason, there is a possibility that a fraudulent person may increase the possibility of fraud. However, since the clock signal monitoring means can detect an abnormality in the random number clock signal, the fraudulent act may be reliably detected. . In addition, the frequency of the random number clock is more likely to be lower than the frequency of the system clock generated from the external clock, so the accuracy of detecting the frequency change of the random number clock can be increased, and an abnormality in the random number clock can occur. May be detected quickly, and various processes depending on the abnormality may be performed.
The package may be made of a non-transparent member.
With such a configuration, even if it is difficult to visually recognize the back side of the package, an illegal circuit is retrofitted to the back side of the package or the gap between the package and the substrate (or IC socket). In some cases, fraud can be easily detected and fraud can be prevented.
Moreover, the notch which does not provide the said terminal may be formed in at least one of the edge part of said 1st side surface or the edge part of said 2nd side surface in the said package.
With this configuration, the specific region of the package can be viewed from various angles through the second part, and in addition, the specific region of the package is different from the second part through the third part. Visible from an angle. For this reason, it is possible to easily find a fraudulent act such as attaching a fraudulent circuit to the back side of the package or the gap between the package and the substrate (or IC socket), and to prevent the fraudulent act.
Further, the pachinko machine 100 according to the present embodiment includes a random number clock generation circuit (for example, a random number crystal oscillator 314a) that generates a random number clock, and a system clock generation circuit (for example, a system crystal oscillator 314b) that generates an external clock. ) And an IC socket in which a game control microcomputer (for example, package 740) for controlling the game can be mounted, and a system clock of the game control microcomputer The first signal line (for example, the first signal line 1006) connects the terminal (for example, the external clock EX terminal or the socket terminal of the IC socket electrically connected to the external clock EX terminal) to the clock generation means. And the game control microcomputer The second signal line (for example, the second signal line 1008) from the clock terminal (for example, the random number clock RCK terminal or the socket terminal of the IC socket electrically connected to the random number clock RCK terminal) to the clock generation means. ), The length from the random number clock terminal of the second signal line to the outer edge of the IC socket (for example, the distance of L22 shown in FIG. 34B) is set to the length of the first signal line. It is a gaming machine characterized in that it is longer than the length from the system clock terminal to the outer edge of the IC socket (for example, the distance L21 shown in FIG. 34 (b)). The “system clock terminal” and the “random number clock terminal” according to the present invention are concepts including terminals (for example, socket terminals of an IC socket) electrically connected to these terminals.

  According to the pachinko machine 100 according to the present embodiment, since the distance from the system clock terminal of the first signal line to the outer edge of the IC socket can be shortened, the external clock signal output from the clock generation means is In addition to being able to be stably supplied to the game control microcomputer, the system clock signal generated based on this external clock signal can also be stably supplied to the CPU core and internal circuits. .

  The length of the signal line connecting the supply source and the supply destination of the clock signal is generally set as short as possible so that no disturbance is applied to the clock signal. The distance from the terminal to the outer edge of the IC socket is deliberately set longer, and the random number clock signal passing through the second signal line is configured to be easily affected by the disturbance, thereby counting based on the random number clock signal. There are cases where the randomness of the random number generated by the random number circuit can be further improved by providing variation in the update timing of the count value of the random number circuit that counts the values.

  Clock signal monitoring means for determining that the random number clock has become abnormal when the frequency of the random number clock is lower than the frequency of the clock obtained based on the system clock generated from the external clock A portion of the second signal line from the random number clock terminal to the outer edge of the IC socket, than a portion of the second signal line from the outer edge of the IC socket to the clock generation means. It is difficult to see (for example, it is difficult to see from above the substrate by covering the part with a package or IC socket), and the IC is connected to the IC from the system clock terminal of the first signal line. The portion from the outer edge of the IC socket of the first signal line to the outer edge of the socket is connected to the clock generating means. It may be visually difficult to configure than the parts of the body.

  With such a configuration, the frequency of the random number clock is more likely to be lower than the frequency of the system clock generated from the external clock, so that the detection accuracy of the frequency change of the random number clock can be increased. In some cases, it is possible to quickly detect an abnormality in the random number clock and perform various processes according to the abnormality. In addition, since it is not possible to grasp that the length of the second signal line is set to be long at first glance, there is a possibility that a fraudster may increase the possibility of fraud. Since abnormalities in the signal can be detected, there are cases where fraudulent acts can be detected with certainty.

  Further, a terminal adjacent to the random number clock terminal may be a terminal (for example, a chip select terminal, a read signal output terminal, a write signal output terminal) connected to a control signal line.

  With this configuration, it is possible to configure the random number clock signal to be easily affected by disturbance from the control signal line, and the random number circuit counts the count value based on the random number clock signal. There is a case where the randomness of the random number value generated by the random number circuit can be further improved by providing variation in the value update timing.

  In the above embodiment, an example of a pachinko machine using a game ball as a game medium has been 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.

<Overall configuration>
First, the overall configuration of a slot machine 100 according to another example 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 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.

<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. 47 and 48.

  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. The CPU 310 is connected to an input interface 360 for receiving an external signal, and a start lever sensor 321, a stop button sensor 322, a medal insertion button sensor 323, a checkout switch via the input interface 360 every interrupt time.

The medal insertion button sensor 323 is a sensor for detecting which medal insertion button is pressed when one of the medal insertion buttons 130 and 131 is pressed. The settlement switch sensor 324 is provided on the settlement button 132, and when the settlement button 132 is pressed once, the stored medals and the bet medals are settled and paid out. The medal payout sensor 326 is a sensor for detecting a payout medal. The power determination circuit 327 is a circuit for detecting the interruption of the power supplied to the slot machine 100.

  Further, an input interface 361 and output interfaces 370 and 371 are connected to the CPU 310 via the address decoding circuit 350 to the address bus. The CPU 310 exchanges signals with external devices via these interfaces. An index sensor 325 is connected to the input interface 361. The index sensor 325 is installed at a predetermined position on the mounting base of each of the reels 110 to 112, and becomes a high level every time the light shielding piece provided on the reels 110 to 112 passes through the index sensor 325. When detecting this signal, the CPU 310 determines that the reel has made one rotation, and resets the rotational position information of the reel to zero. The output interface 370 drives a motor of a reel motor driving unit 330 that controls a motor for driving the reel and a hopper (a device for paying out medals accumulated in the bucket from the medal payout outlet 155). Hopper motor drive unit 331, a game lamp 340 (specifically, a winning line display lamp 120, a start lamp 121, a replay lamp 122, a notification lamp 123, a medal insertion lamp 124, etc.), and a 7 segment (SEG) display A device 341 (a payout number display 125, a game information display 126, a stored number display 127, etc.) is connected.

  A random number generation circuit 317 is connected to the CPU 310 via a data bus. The random number generation circuit 317 is an increment counter capable of incrementing a value within a certain range based on a clock oscillated from the crystal oscillator 311 and the crystal oscillator 316 and outputting the count value to the CPU 310, which will be described later. Used for various lottery processes, including internal lottery for winning positions.

  Although not shown, the main control unit 300 compares the frequency of the system clock input from the clock correction circuit 314 with the frequency of the random number clock input to the random number generation circuit 317, and the frequency of the random number clock is equal to or lower than the system clock. A frequency generation circuit for setting the clock signal status bit of the internal information register to 1 at the same frequency. 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 CPU 310 of the main control unit 300 detects any abnormality in the random number clock ( For example, when it is determined that the wiring pattern connecting the random number generation circuit 317 and the crystal oscillator 316 is broken, and the clock signal status bit of the internal information register is set to 0 (the frequency of the random number clock is the system clock) If the frequency is less than the frequency of the random number), it is determined that the random number clock is normal. In addition, although not shown, the main control unit 300 includes a verification block block that is connected to an external verification machine and performs verification of the chip (check for authenticity of the chip). In addition, the first signal line from the random number generation circuit 317 to the crystal oscillator 316 is wired to be longer than the second signal line from the clock correction circuit 314 to the crystal oscillator 311.

  An output interface 371 for transmitting a command to the sub control unit 400 is connected to the data bus of the CPU 310.

  An input interface 461 for receiving a main control command from the main control unit 300 is connected to the CPU 410 via a data bus, and an effect process that excites the entire game based on the command received via the input interface 461. Etc. are executed. A sound source IC 480 is connected to the data bus and address bus of the CPU 410. The sound source IC 480 controls sound according to a command from the CPU 410. The sound source IC 480 is connected to a ROM 481 that stores sound data.

<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.

<Game medal insertion process>
Next, the game medal insertion process in the main process will be described with reference to FIG. This figure is a flowchart showing the flow of game medal insertion processing.

  In step S1301, the clock signal status bit in the internal information register is referred to and it is determined whether or not the clock signal status bit is set to 1. If the clock signal status bit is set to 1 (when the random number clock RCK is abnormal), the process proceeds to step S1302, and if not, the process proceeds to step S1303.

  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.

  The Main CPU 310 includes a hardware timer that generates a timer interrupt at a predetermined cycle (about once every 1.504 ms in the present embodiment), and executes timer interrupt processing at a predetermined cycle triggered by the timer interrupt.

  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,
When the clock signal status bit of the internal information register is set to 0 (when the frequency of the random number clock is less than the system clock frequency), it is determined that the random number clock is normal, and the next step S1212 is performed. Proceed to

  In step S1212, a control command is output to the sub-control unit 400, and in step S1213, various counter timers (for example, the above-described security signal output standby timer) stored in the RAM 313 are updated.

  In step S1214, it is determined whether or not the voltage drop signal is on, that is, whether or not a predetermined voltage is supplied to the slot machine 100. If the voltage drop signal is on (when a predetermined voltage is not supplied to the slot machine 100), the process proceeds to step S1217. If the voltage drop signal is off (a predetermined voltage is supplied to the slot machine 100). If yes, the process proceeds to step S1215.

  In step S1215, the register saved in step S1201 is restored, and in step S1216, an interrupt is set to be permitted.

  In steps S1217 to S1220, a power interruption process is performed. More specifically, in step S1217, the current stack pointer is saved, and in step S1218, the power status is updated to “power failure”. In step S1219, the checksum is calculated and set using the value stored in the RAM 313. In step S1220, writing to the RAM 313 is prohibited, and an infinite loop is entered.
