FIG. 5 is a block diagram showing an example of a configuration around the CPU 56 on the main board 31. As shown in FIG. 5, a power supply cutoff signal (voltage drop signal) from a power supply monitoring unit mounted on a power supply board or the like that generates various voltages used in the gaming machine is supplied to a non-maskable interrupt terminal (XNMI terminal) of the CPU 56. )It is connected to the. The power supply monitoring circuit
This circuit monitors the voltage of any one of various DC power supplies used by the gaming machine and detects a drop in the power supply voltage.
In this embodiment, the power supply voltage of VSL is monitored, and when the voltage value becomes equal to or lower than a predetermined value, a low-level power-off signal is generated. VSL is the largest DC voltage used in gaming machines, and is +30 V in this example. Therefore, C
The PU 56 can confirm the occurrence of power interruption by the interrupt processing.

FIG. 5 also shows a system reset circuit 65. The reset IC 651 sets the output to a low level for a predetermined time determined by the capacity of an external capacitor when the power is turned on, and sets the output to a high level after a predetermined time has elapsed. That is, the reset signal is raised to a high level to make the CPU 56 operable. The reset IC 651 monitors the power supply voltage VSL, which is the same power supply voltage as the power supply voltage monitored by the power supply monitoring circuit, and determines that the voltage value is a predetermined value (lower than the power supply voltage value at which the power supply monitoring circuit outputs a power-off signal). Value), the output goes low.
Therefore, the CPU 56 performs a predetermined power supply stop processing in response to a power-off signal from the power supply monitoring circuit, and then performs a system reset.

As shown in FIG. 5, the reset signal from the reset IC 651 is input to the NAND circuit 947 and to the clear terminal of the counter IC 941 via the inverting circuit (NOT circuit) 944. Counter I

45, 946 and input to the NAND circuit 947. The Q6 output of the counter IC 941 is input to a clock terminal of a flip-flop (FF) 942.
The D input of the flip-flop 942 is fixed at a high level, and the Q output is input to an OR circuit (OR circuit) 949. The other input of the OR circuit 949 is connected to the NAND circuit 9.
The output of 47 is introduced via NOT circuit 948. The output of the OR circuit 949 is connected to the reset terminal of the CPU 56. According to such a configuration, two reset signals (low-level signals) are supplied to the reset terminal of the CPU 56 when the power is turned on.
Starts operation reliably.

For example, the detection voltage of the power supply monitoring circuit (the voltage at which the power supply cutoff signal is output) is set to +22 V, and the detection voltage for setting the reset signal to low level is set to +9 V. In such a configuration, the power supply monitoring circuit and the system reset circuit 65 are connected to the same power supply VSL.
, The difference between the timing at which the voltage monitoring circuit outputs the power-off signal and the timing at which the system reset circuit 65 outputs the system reset signal can be reliably set to a desired predetermined period. The desired predetermined period is a period from the start of the power supply stop processing in response to the power supply cutoff signal from the power supply monitoring circuit until the power supply stop processing is completely completed.

While power is not supplied from the +5 V power supply, which is the driving power supply of the CPU 56 and the like, at least a part of the RAM is backed up by the backup power supply supplied from the power supply board. Is saved. Then, when the + 5V power supply is restored, a reset signal is issued from the system reset circuit 65, so that the CPU 56 returns to the normal operation state. At that time, since the necessary data is stored in the backup RAM, it is possible to return to the gaming state at the time of the occurrence of the power failure when recovering from a power failure or the like.

In the configuration shown in FIG. 5, two reset signals (low-level signals) are applied to the reset terminal of the CPU 56 when the power is turned on. When the CPU to be released is used, the circuit elements indicated by reference numerals 941 to 949 are unnecessary. In that case, reset I
The output of C651 is directly connected to the reset terminal of CPU56.

It is a device (collator) that inputs and verifies the validity of identification information.

Further, a power supply voltage (Vcc in this example) is supplied to the connector 351c via the connector 351c. Therefore, the external device can receive power supply from the gaming machine through the connector 351c. If a short circuit occurs at the external device or at the location of the connector 351c, the main board 31 is adversely affected.
It is supplied via the overcurrent prevention circuit 201. The overcurrent prevention circuit 201 includes a component that stops power supply when an overcurrent is detected.

Here, the power supply terminal as a power supply means for the external device is one terminal of the connector 351c, but may be another terminal (or another connector) from the connector 351c. Also, power is supplied to the power supply terminal while power is being supplied to the gaming machine. In this embodiment, the voltage supplied to the power supply terminal is generated by the power supply substrate. However, when the main substrate 31 has a voltage generation circuit, the voltage may be supplied from the voltage generation circuit. Good.

The connection between the connector 351c and the external device may be a method in which a cable from the external device is directly connected to the connector 351c. A cable may be connected to the relay board so that a connector provided on the relay board is connected to an external device.
When such a relay board is provided, the main board 31 and the relay board are collectively defined as a control board.

Further, in the example shown in FIG.
Although the input means and the output means using the photocoupler and the buffer circuit have been illustrated, various modifications in accordance with the performance of the element used and the configuration of the external device can be considered. For example, if the external device is configured to perform signal input / output by detecting a voltage level, the photocoupler is unnecessary. When an input / output port having sufficient driving capability is used, a buffer circuit is not required. In addition, various modifications that match the signal input / output method of the external device used are conceivable.

FIG. 7 is an explanatory diagram showing an example of mapping of the ROM area. In the example shown in FIG. 7, the ROM area includes a program area in which a game control program is stored, a data area in which fixed data used by the game control program is stored, and a program management area (system area). is there. The system area stores a security check program and one or more types of identification information and an arithmetic expression (encryption program) for creating the identification information.

The system area is a management area in which a game control program (user program) cannot be stored. In the system area, check data according to a regular game control program is set, and the security check program performs a check including such data. Therefore, if the contents of the system area are modified, the security check cannot be passed and the game control program is not started.

FIG. 8 is an explanatory diagram showing an example of an identification information request code from an external device, identification information to the external device, and a format of a periodic signal. In the example shown in FIG. 8, the identification information request code, the identification information, and the periodic signal are composed of a plurality of bits, and are input and output in synchronization with the clock signal.
For example, each of the identification information request code, the identification information, and the periodic signal has a 1-byte configuration. However, the signal length is 1
Bytes are only examples. For periodic signals,
One pulse may be used.

As shown by broken lines in FIG. 8, a start bit and a stop bit may be added to the identification information request code, the identification information, and the periodic signal. In this case, transmission and reception can be synchronized by the start bit, so that a clock signal need not be used.

Next, the operation of the gaming machine will be described.

FIG. 9 is a flowchart showing the main processing executed by the CPU 56 on the main board 31. When the power to the gaming machine is turned on, in the main process,
First, the CPU 56 performs necessary initial settings.

In the initial setting process, the CPU 56 first sets interrupt prohibition (step S1). Next, the interrupt mode is set to the interrupt mode 2 (step S2), and a stack pointer designated address is set to the stack pointer (step S3). Then, the internal device registers are initialized (step S4). After initializing a built-in device (built-in peripheral circuit) CTC (counter / timer) and PIO (parallel input / output port) (step S5), the RAM is set to an accessible state (step S6).

Note that the interrupt mode 2 is an interrupt mode of the CPU 56 used in the present embodiment, in which the value (1 byte) of the specific register (I register) and the interrupt vector output from the built-in device are output. In this mode, an address synthesized from (1 byte: least significant bit 0) indicates an interrupt address.

Then, it is checked whether or not the data protection processing of the backup RAM area (for example, the power failure occurrence NMI processing such as the addition of parity data) has been performed when the power is turned off (step S7). In this embodiment, when an unexpected power failure occurs, a process for protecting data in the backup RAM area is performed. The case where such protection processing has been performed is regarded as backup. After confirming that there is no backup, the CPU 56 executes an initialization process.

After confirming that there is a backup, the CPU 5
6 performs a game state restoration process for returning the internal state of the game control means and the control state of the electric component control means such as the display control means to the state at the time of power-off (step S8). Then, the saved value of the PC (program counter) stored in the backup RAM area is set in the PC, and the program returns to that address.

In the initialization process, the CPU 56 first sets R
An AM clear process is performed (step S11). In addition, a predetermined work area (for example, a normal symbol determination random number counter, a normal symbol determination buffer, a special symbol left middle right symbol buffer,
An initial value setting process for setting an initial value to a payout command storage pointer or the like is also performed. Further, a process for initializing the sub-boards (the lamp control board 35, the payout control board 37, the voice control board 70, and the symbol control board 80) is executed (step S13). The process of initializing the sub board is
For example, a process of transmitting an initialization command.

Then, the register of the CTC provided in the CPU 56 is set so that the timer is interrupted periodically every 2 ms (step S14). That is,
A value corresponding to 2 ms is set in a predetermined register (time constant register) as an initial value. Since the interrupt is prohibited in step S1 of the initial setting process, the interrupt is permitted before the initialization process is completed (step S1).
5).

In this embodiment, the built-in C
The TC is set to repeatedly generate a timer interrupt. In this embodiment, the repetition period is set to 2 ms. When a timer interrupt occurs, the CPU 56
Sets a timer interrupt flag indicating that a timer interrupt has occurred, for example.

Execution of initialization processing (steps S11 to S1)
When 5) is completed, the process proceeds to a loop process in which the main process checks whether or not a timer interrupt has occurred (step S17). In the loop, a display random number update process (step S16) is also executed.

The CPU 56 determines in step S17
Upon recognizing that a timer interrupt has occurred, step S2
The game control processing of 1 to S31 and the processing of step S32 are executed. In the game control process, first, the CPU 56 inputs the states of the switches such as the gate sensor 12, the starting port sensor 17, the count sensor 23, and the winning port switches 19a, 19b, 24a, 24b via the switch circuit 58. Is determined (switch processing:
Step S21).

Next, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S22).

Next, a process of updating each counter indicating a random number for determination, such as a random number for big hit determination used in game control, is performed (step S23). The CPU 56 further includes:
A process for updating a display random number such as a random number for determining the type of stop symbol is performed (step S24).

Further, the CPU 56 performs a special symbol process (step S25). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S26). In the normal symbol process process, a corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display 10 using the 7-segment LED in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state.

Next, the CPU 56 sets a display control command relating to a special symbol in a predetermined area of the RAM 55 and performs a process of transmitting the display control command (special symbol command control process: step S27). Further, a display control command relating to a normal symbol is set in a predetermined area of the RAM 55, and a process of transmitting the display control command is performed (ordinary symbol command control process: step S28).

Further, the CPU 56 performs an information output process of outputting data such as jackpot information, start information, and probability variation information supplied to the hall management computer (step S29).

Further, the CPU 56 issues a drive command to the solenoid circuit 59 when a predetermined condition is satisfied (step S30). The solenoid circuit 59 drives the solenoids 16 and 21 in response to the drive command, and brings the variable winning ball device 15 or the open / close plate 20 into an open state or a closed state.

Then, the CPU 56 controls the switches 17, 23, 19a, and 19 for detecting a winning in each winning opening.
A prize ball process for setting the number of prize balls based on the detection outputs of b, 24a and 24b is executed (step S31). Specifically, a payout control command is output to the payout control board 37 in response to the winning detection. The payout control CPU 371 mounted on the payout control board 37 drives the ball payout device 97 according to the payout control command.

With the above control, in this embodiment, the game control process is started every 2 ms.
In this embodiment, for example, in the timer interrupt processing, only a flag indicating that an interrupt has occurred is set, and the game control processing is executed in the main processing.
The game control process may be executed by a timer interrupt process.

In this embodiment, the collation information input / output processing (step S32) is executed following the prize ball processing. In the collation information input / output processing, the CPU 56 detects an identification information request code from an external device, performs processing to output identification information when the identification information request code is received, and performs processing to output a periodic signal.

FIG. 10 is a flowchart showing an example of the collation information input / output processing. In the processing example shown in FIG. 10, in the collation information input / output processing, the CPU 56 first performs a periodic signal output processing (step S41). Periodic signal is 1
If it is a pulse, one pulse is output to the corresponding bit of the output port 572 here. When the periodic signal is a signal composed of a plurality of bits, the data of the bit is output to the corresponding bit of the output port 572 for the time allocated to each bit.

When the clock signal is used, for example, in step S41, a high level is output to the corresponding bit of the output port 572 assigned to the clock signal for a time corresponding to 1/2 clock time. The clock signal can be output by outputting a low level to the corresponding bit of the output port 572 assigned to the clock signal for a time corresponding to the next 1/2 clock time.

Next, it is confirmed whether or not the output processing of the identification information is ongoing (step S42). In this embodiment, the collation information input / output processing is executed every 2 ms. However, when the signal length of the identification information is 2 ms or more, the identification information is output when the collation information input / output processing is executed a plurality of times. Can be completed. In such a case, in the collation information input / output processing, a situation may occur in which the identification information output processing is being continued.

If the identification information output process is not being continued, an identification information request code reception process is performed (step S43). That is, at the rising edge of the clock signal (when the level is changed from low level to high level), the corresponding bit of the input port 571 is input, and the input bit is stored in a predetermined RAM area. Next, the CPU 56 checks whether or not the reception of the identification information request code has been completed (Step S44).
That is, the past 8 bits (when the identification information request code has a 1-byte configuration) input from the input port 571 are
The data is compared with the data defined as the identification information request code, and if they match, it is determined that the reception of the identification information request code is completed. The data defined as the identification information request code is set, for example, in the system area.

When the clock signal is not used, when the start bit is detected, the input port 5
If a corresponding bit of 71 is input and a stop bit is detected after inputting 8 bits, it is determined that some data has been received, the received data is compared with data specified as an identification information request code, and if they match, the identification information is determined. It is determined that the reception of the request code has been completed.

When the reception of the identification information request code is completed,
The identification information corresponding to the identification information request code is selected (step S45). For example, as an identification information request code,
If there are A to X and the corresponding identification information is set in the system area, the identification information (one of A 'to X') corresponding to the type of the received identification information request code is selected. Read from the system area. Then, the output of the identification information is started (step S46).

When the start bit is added to the identification information, the output of the start bit is started in step S46, and a flag indicating that the process is being continued is set. If the start bit is not added, a flag indicating that the processing is being continued is simply set.

When it is confirmed in step S42 that the output process is being continued, if the process is not completed (step S47), an identification information output process is executed (step S48). That is, at the falling edge of the clock signal (when the level is changed from high level to low level), the corresponding bit of the output port 572 is changed according to the content of the identification information. When a clock signal is not used, if a predetermined time (time until each bit output timing) has elapsed from the start bit output timing, the output port 57 is used.
2 corresponding bits are changed according to the contents of the identification information.

By the above processing, the main board 31 outputs a periodic signal every 2 ms, and outputs corresponding identification information according to the identification information request code.

The identification information is encrypted by a predetermined encryption method. Therefore, in the external device, the decoding process is performed based on the received identification information data, and when the decoding result matches the regular identification information,
It can be determined that the identification information corresponding to the identification information request code has been received from the authorized microcomputer (CPU 56). If they do not match, it can be determined that an unauthorized microcomputer is mounted.

Instead of outputting the identification information determined according to the identification information request code, an arithmetic expression (encryption method) corresponding to the identification information request code may be used. Each arithmetic expression is set, for example, in the system area. Therefore, in that case, as shown in the flowchart of FIG. 11, when the reception of the identification information request code is completed, the CPU 56 loads an arithmetic expression corresponding to the received identification information request code from the system area (step S5).
1), an operation is performed on predetermined basic data to generate identification information (step S5)
2).

Note that the system shown in FIG. 10 and the system shown in FIG. 11 may be used together. That is, when the reception of the identification information request code is completed, the data that is the source of the identification information corresponding to the received identification information request code is loaded from the system area, and the arithmetic expression is loaded. May be calculated in accordance with the calculation formula, and the calculation result may be output to the output port 572.

According to each of the above embodiments, main substrate 31
If an authorized microcomputer is mounted on the external device, the external device receives the identification information determined corresponding to the identification information request code. When an unauthorized microcomputer is mounted on the main board 31, it is difficult to make correct identification information or an arithmetic expression exist in a system area of a ROM built in the microcomputer. Cannot be output. That is, the external device does not receive the identification information determined corresponding to the identification information request code.

Note that the identification information transmission / reception method, identification information request code, and format of the identification information described in the above embodiment are merely examples, and other methods and formats may be used. That is, external connection connectors such as input means and output means for inputting and outputting an identification information request signal and identification information to and from an external device and a connector may be provided on a board or a relay board on which the game control microcomputer is mounted. For example, it is possible to provide an environment in which an external device can detect that an unauthorized microcomputer is mounted.

Further, in each of the above embodiments, the collation information input / output processing is executed in the loop of the main processing, but may be executed at another place. For example, the identification information request code may be introduced into an interrupt terminal to execute the collation information input / output processing in the interrupt processing, or the collation information input / output processing may be executed in the timer interruption processing.

Further, since the power supply line can be supplied to the connector, the external device can check whether or not the unauthorized microcomputer is mounted without having the power supply. However, the external device may be provided with a power supply or receive power supply from another power supply device without supplying power from the gaming machine.
