  On the other hand, in recent years, unauthorized modification and other changes to these gaming machines have become more sophisticated and complicated. In order to prevent these irregularities and to make the pachinko hall sound, it is necessary to detect unauthorized modifications and notify the hall computer or the like.

  However, if the anti-fraud program for preventing fraud is considered the same as the above-described game control program for controlling the progress of the game, the program capacity increases. The problem of taking time, the problem of inducing mistakes at the time of program creation or inspection due to the large capacity, and the problem of being likely to become a hotbed such as program tampering due to the large capacity were considered.

  The above-mentioned issues include not only a main control circuit (game control circuit) equipped with a game control program for controlling the progress of the game, but also a payout control program for payout control of prizes (prize balls, medals, etc.). The same applies to the payout control circuit.

The gaming machine according to the first invention is
A ROM that separates a game control area that stores a game control program for controlling the progress of the game and a fraud prevention control area that stores a fraud prevention program for preventing fraud;
A game control circuit including the ROM, a CPU that executes the game control program and the anti-fraud program stored in the ROM, and a RAM that is accessed by the CPU;
The RAM is characterized in that a work area of the game control program and a work area of the fraud prevention program are separated.

Since the ROM provided in the gaming machine according to the first aspect of the invention separates the game control area (game control program) and the anti-fraud control area (program for fraud prevention), it is easy to distinguish the game control program from the anti-fraud program. It is easy to check and check the game control program. As a result, it can be expected to prevent the occurrence of a program creation error and the alteration of the program. Further, even if the fraud prevention program is tampered with, it is not directly related to the performance of the game.
In addition, since the RAM has a configuration in which the work area of the game control program and the work area of the fraud prevention program are separated, the distinction between the game control program and the fraud prevention program is clear even in the RAM work area. .

In the gaming machine according to the second aspect of the present invention, in the RAM, the work area of the game control program is stored in a preset address space (hereinafter referred to as “area 1”), and the work area of the fraud prevention program is stored. The gaming machine according to the first invention, characterized in that it is outside the area 1, is a configuration example for separating the work area of the game control program and the work area of the fraud prevention program.

The gaming machine according to claim 1 is:
A game control circuit for controlling the progress of the game;
A prize balls control region which stores prize balls control program for the control of the prize balls, a ROM that separate the winning balls fraud control region which stores winning balls fraud prevention program for preventing abuse A prize ball control circuit comprising: a CPU for executing the prize ball control program and the prize ball fraud prevention program stored in the ROM; and a RAM accessed by the CPU;
The RAM is a gaming machine in which a work area of the prize ball control program and a work area of the fraud prevention program are separated,
The prize ball control circuit includes a magnetic sensor for detecting a magnetic force exerted on the gaming machine from the outside, a door opening switch for detecting that the front frame is opened, and the gaming machine is vibrated. Connecting at least one of the vibration sensor and
The game control circuit is connected to a launch control circuit and stores a game control area storing a game control program for controlling the progress of the game and a game fraud prevention program for preventing fraud A ROM that is separated from the gaming fraud prevention control area, a CPU that executes the game control program and the game fraud prevention program stored in the ROM, and a work area of the game control program that is accessed by the CPU And a RAM for separating a work area of the gaming fraud prevention program,
If the detection signal of the magnetic sensor, the door opening switch, or the vibration sensor is a detection level, the prize ball control circuit transmits a fraud detection signal indicating that to the game control circuit,
When the game control circuit receives the fraud detection signal, the game control circuit sets a fraud flag in a work area of the game control program in the RAM ,
The game control circuit outputs a signal for instructing to stop the launch to the launch control circuit when the fraud flag is set.

Since the ROM for the payout control circuit provided in the gaming machine according to claim 1 separates the payout control area (payout control program) and the fraud prevention control area (fraud prevention program), the payout control program and the fraud prevention program Are easily distinguished, and the inspection and check of the payout control program are simple. As a result, it can be expected to prevent the occurrence of a program creation error and the alteration of the program. Further, even if the fraud prevention program is tampered with, it is not directly related to the performance of the game.
Further, since the RAM has a configuration in which the work area of the payout control program and the work area of the fraud prevention program are separated, the distinction between the payout control program and the fraud prevention program is also clear in the RAM work area. .

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example 1]
As shown in FIG. 1, the pachinko machine 21 which is a kind of gaming machine includes a front frame 23 pivotally supported by a rectangular outer frame 22.

A glass plate is fitted into a circular window 24 provided in the front frame 23, and a game board 30 (see FIG. 2) is housed behind it.
Below the window 24, an upper plate 26, a lower plate 27, a firing handle 28, and the like are attached.

  As shown in FIG. 2, the game board 30 is formed with a substantially circular game area 33 surrounded by guide rails 31a and 31b. In the game area 33, the center role 32, the production symbol display unit 10 assembled to the center role 32, the gate 34, the start winning opening 35 serving as the start area, the ordinary electric accessory 36 also serving as the start area, and the big prize. An attacker 38 or the like having a mouth 37 is disposed. Also, the game board 30 is provided with a normal winning opening, a game nail, a windmill, etc., but these are in accordance with known techniques and are not shown and described.

Next, the control system of the pachinko machine 21 will be described with reference to FIG. However, FIG. 3 shows only the main part of the control system, and the illustration of the thin parts related to the present invention is omitted.
This control system is configured with a game control circuit 1 as the center. The game control circuit 1 is connected to a payout control circuit 4, a launch control circuit 5, a relay board 6, an external output terminal board 9, and a special symbol display unit 8. ing. Although not shown in the drawings, the game control circuit 1 has a winning-port switch for detecting a winning ball at each of the normal winning ports equipped in the game board 30 and a start for detecting a winning ball at the starting winning port 35. Mouth switch, ordinary electric role switch for detecting the winning ball to the ordinary electric accessory 36, normal symbol start switch for detecting that the game ball has passed the gate 34, for counting the winning ball to the big winning port 37 A count switch, a large winning opening solenoid for opening and closing the large winning opening 37, a normal accessory solenoid for opening and closing the ordinary electric accessory 36, and the like are also connected.

  The game control circuit 1 includes a ROM that stores a game control program, a fraud prevention program, and the like, a CPU that functions as a game control means by executing the game control program, and a RAM that functions as a work area for operations and the like. In addition to these, an external input / output circuit for inputting / outputting each circuit or various switches and various actuators is also provided.

  The ROM of the game control circuit 1 stores a game control program and a fraud prevention program (however, not only these are stored), but the game control circuit 1 (8-bit one-chip microcomputer) ) Is preliminarily set as an address space for area 1 on the memory map, and the game control program is stored in the range of addresses 0000H to 0E01H in area 1. The fraud prevention program is stored in the range of 1100H to 1500H following 10FFH which is the end of area 1.

  Therefore, the game control area (0000H to 0E01H) in which the game control program is stored and the fraud prevention control area (1100H to 1500H) in which the fraud prevention program is stored are separated. Therefore, it is easy to distinguish between the game control program and the fraud prevention program, and the game control program can be easily inspected and checked. As a result, it can be expected to prevent the occurrence of a program creation error and the alteration of the program. Further, even if the fraud prevention program is tampered with, it is not directly related to the performance of the game.

  Moreover, since the surplus area (0E02H to 0E01H) of area 1 exists as an unused area between the game control area and the fraud prevention control area, the separation between the game control area and the fraud prevention control area is clear. , Improve the above effects.

The address space allocated to the RAM in the memory map of the 8-bit one-chip microcomputer of the game control circuit 1 has an address space set in advance as area 2, and part of this area 2 is game control. Assigned as the work area of the program. The work area of the fraud prevention program is assigned to an area outside the area 2 in the address space assigned to the RAM.
Accordingly, the work area of the anti-fraud program is separated from the work area of the RAM, and the distinction between the game control program and the anti-fraud program is clear also in the RAM work area.

  The game control circuit 1 is input with detection signals such as the above-described winning port switch, start port switch, normal power switch, normal symbol start switch, and count switch (illustrated as a start signal and the like).

  The game control circuit 1 operates according to the installed program, generates various commands related to the progress of the game based on the above-described detection signals, etc., and sends them to the payout control circuit 4, the launch control circuit 5, and the sub-integrated circuit 3. Output. In addition, the game control circuit 1 controls the display of the special symbol display unit 8 and controls the operations of the special prize opening solenoid, the ordinary accessory solenoid, etc. (illustrated as a solenoid or the like).

  In addition, several kinds of predetermined signals (for example, jackpot signal, probability variation signal, etc.) among various signals output from the game control circuit 1 are output to the external output terminal plate 9. The external output terminal plate 9 is connected to a hall computer (not shown).

  As with the game control circuit 1, the payout control circuit 4 is also configured as a logical operation circuit centered on a one-chip microcomputer incorporating a CPU, ROM, and RAM, and is provided with an external input / output circuit. The game control circuit 1 and the payout control circuit 4 can communicate bidirectionally.

  As is well known, the payout control circuit 4 controls a payout device (not shown) for paying out a prize ball. The payout control circuit 4 includes a magnetic sensor 7a for detecting the magnetic force exerted on the pachinko machine 21 (especially the game board 30) from the outside, and a full switch 7b for detecting that the lower plate 27 is full. A door opening switch 7c for detecting that the front frame 23 is opened and a vibration sensor 7d for detecting that the pachinko machine 21 is vibrated are connected, and detection signals from these are input.

  Similarly to the game control circuit 1, the launch control circuit 5 is also configured as a logical operation circuit centered on a one-chip microcomputer incorporating a CPU, ROM, and RAM, and is provided with an external input / output circuit. The game control circuit 1 and the launch control circuit 5 are unidirectionally communicated from the game control circuit 1 to the launch control circuit 5. The launch control circuit 5 controls a launch device (not shown) for launching a game ball.

The special symbol display unit 8 is composed of, for example, a 7-segment display, and can perform variable display and static display (deterministic display) of symbols.
The relay board 6 is a board on which no CPU is mounted. The relay board 6 is a board that relays communication from the game control circuit 1 to the sub-integrated circuit 3, and does not process data even if noise removal or signal conversion may be performed.

  Communication between the game control circuit 1 and the relay board 6 is one-way communication from the game control circuit 1 to the relay board 6, and communication between the relay board 6 and the sub-integrated circuit 3 is performed from the relay board 6 to the sub-integrated circuit 3. One-way communication to.

  In order to realize such one-way communication, the game control circuit 1 is provided with a one-way communication circuit such as an inverter, a buffer, or a latch circuit as a communication circuit with the relay board 6. The relay board 6 is also provided with a similar one-way communication circuit, and the sub integrated circuit 3 is also provided with a similar one-way communication circuit for communication with the relay board 6. Note that even if such a one-way communication circuit is not provided in each of the game control circuit 1, the relay board 6, and the sub-integrated circuit 3, communication from the game control circuit 1 to the relay board 6 is possible if any one of them is provided. In addition, communication from the relay board 6 to the sub integrated circuit 3 can be made one-way communication.

  Between the sub-integrated circuit 3 and the game control circuit 1, a relay board 6 without a CPU is interposed, and a circuit configuration capable of transmitting only from the game control circuit 1 to the sub-integrated circuit 3 in the connection before and after the relay board 6 Therefore, it is difficult to perform fraud, and the effect of being easy to find fraud is exerted. That is, in order to perform an illegal act from the sub-integrated circuit 3 to the game control circuit 1, it is necessary to perform an illegal act on the double one-way communication circuit, and the relay board 6 is a board on which no CPU is mounted. Therefore, it is easy to detect a fraudulent act directly from the relay board 6. First, in order to perform an illegal act from the sub integrated circuit 3 to the game control circuit 1, it is necessary to perform wiring to transmit from the sub integrated circuit 3 to the game control circuit 1. However, because the game control circuit 1 and the sub-integrated circuit 3 are connected via the relay board 6, the wiring connecting the sub-integrated circuit 3 and the game control circuit 1 without the relay board 6 is illegal. Can be regarded as. That is, it is easy to find wiring due to fraud. Alternatively, it is conceivable that an illegal game is performed from the relay board 6 to the game control circuit 1 through wiring by an illegal act. However, since the relay board 6 is configured as a board on which the CPU is not mounted, unauthorized modification can be easily found.

A sound / lamp actuator 11 and a symbol control circuit 2 are connected to the sub-integrated circuit 3, and an effect symbol display unit 10 which is a liquid crystal display device is connected to the symbol control circuit 2.
Communication between the sub integrated circuit 3 and the sound / lamp actuator 11 and the symbol control circuit 2 is one-way communication from the sub integrated circuit 3 to the sound / lamp actuator 11 and the symbol control circuit 2. Similarly, the communication between the symbol control circuit 2 and the effect symbol display unit 10 is one-way communication from the symbol control circuit 2 to the effect symbol display unit 10.

  The sub-integrated circuit 3 is configured as a logic operation circuit centered on a one-chip microcomputer (CPU), like the game control circuit 1. Similar to the game control circuit 1, the symbol control circuit 2 is also configured as a logical operation circuit centered on a one-chip microcomputer (CPU).

  The sub-integrated circuit 3 receives the data transmitted from the game control circuit 1 and distributes the data into data for image control, electrical decoration control, and sound effect control, for electrical decoration control and sound effect control Is used by itself, and image control data is transmitted to the symbol control circuit 2. Further, data generated by the sub integration circuit 3 based on data sent from the game control circuit 1 may be transmitted to the symbol control circuit 2 as image control data.

  The sound / lamp actuator 11 connected to the sub-integrated circuit 3 is mainly composed of driving elements such as a transistor, a sound source IC, and an amplifier. The sound / lamp actuator 11 generates a sound signal based on the signal from the sub-integrated circuit 3 to , And various LEDs and lamps such as jackpot lamps and error lamps are turned on. That is, the sub-integrated circuit 3 controls the sound output and light emission such as electrical decoration by outputting a signal generated based on the electrical decoration control data and the sound effect control data to the sound / lamp actuator 11.

  The symbol control circuit 2 generates an image based on the data sent from the game control circuit 1 (actually, the sub-integrated circuit 3), and displays the generated image on the effect symbol display unit 10 to display the effect symbol display. The display of the unit 10 is controlled.

Next, the operation of the game control circuit 1 related to the display control of the special symbol display unit 8 will be described.
FIG. 4 is a flowchart of a special symbol lottery process executed by the game control circuit 1. The special symbol lottery process is one of the subroutines of the game control program.

  In the special symbol lottery process, the game control circuit 1 first determines whether or not the detection signal of the start opening switch or the ordinary electric role switch is input, that is, whether or not the game ball has won the start winning opening 35 or the ordinary electric accessory 36. Is determined (S1). If a negative determination is made here, the process returns. On the other hand, if the determination is affirmative (S1: YES), the random number for determination of success / failure is read from the random counter, and determination is made as to whether or not the read random number for determination of success / failure is a winning value, that is, determination of success / failure lottery is performed (S2). Next, the variation time is determined based on the variation time determination random number read from a random counter different from the validity determination random number (S3). Then, the data indicating the result of the lottery determination in S2 (whether it is a hit or miss) and the data specifying the variation time determined in S3 are transmitted to the sub integrated circuit 3 as a variation start command (S4).

  Subsequently, the game control circuit 1 causes the special symbol display unit 8 to start displaying the variation of the special symbol (S5), and if the variation time reaches the variation time determined in S3, the result of the success / failure lottery in S2 (whether or not A special symbol indicating whether it is off or not is determined and displayed (S6).

  On the other hand, the variation start command transmitted to the sub integrated circuit 3 in S4 is transmitted to the symbol control circuit 2. When receiving the variation start command, the symbol control circuit 2 causes the effect symbol display unit 10 to start the effect symbol change display. The variation display of the effect symbol is performed in accordance with the variation pattern determined by the symbol control circuit 2 based on the result of lottery determination (whether or not) and the variation time indicated by the variation start command. Then, when the variation time specified by the variation start command is reached, the effect symbol indicating the result of the lottery determination (whether it is a hit or miss) indicated by the variation start command is fixedly displayed on the effect symbol display unit 10.

  The game control circuit 1 starts the well-known jackpot game and opens the big winning opening 37 when the result of the lottery determination is successful and the special symbol indicating the winning is displayed on the special symbol display unit 8.

Next, operations of the game control circuit 1 and the payout control circuit 4 related to fraud prevention will be described.
First, the fraud detection process executed by the payout control circuit 4 will be described with reference to the flowchart shown in FIG.

  In this fraud detection process, the payout control circuit 4 inputs detection signals from the magnetic sensor 7a, the door opening switch 7c, and the vibration sensor 7d (S11). When the magnetic sensor 7a detects magnetism, the door opening switch 7c detects the opening of the front frame 23, or the vibration sensor 7d detects the vibration of the pachinko machine 21, that is, either detection signal is If it is a detection level (S12: YES), the signal which shows having detected fraud is transmitted to the game control circuit 1 (S13).

Next, the reception process executed by the game control circuit 1 will be described according to the flowchart shown in FIG. This reception process is one of the subroutines of the game control program.
In the reception process, the game control circuit 1 inputs a signal from the payout control circuit 4 (S21). Then, when the signal indicating that the fraud has been detected is transmitted from the payout control circuit 4 (S22: YES), the fraud flag is set in the work area of the game control program (S23).

Next, according to the flowchart shown in FIG. 7, the launch stop process executed by the game control circuit 1 will be described. This firing stop process is one of the subroutines of the game control program.
In the firing stop process, it is determined whether or not an illegal flag is set (S25). If this is set (S25: YES), a firing stop signal is output to the launch control circuit 5 (S26). The launch control circuit 5 that has received the launch stop signal stops the launching device, so that the pachinko game cannot be executed.

  Next, the fraud notification process executed by the game control circuit 1 will be described with reference to the flowchart shown in FIG. This fraud notification process is one of the subroutines of the fraud prevention program.

  In the fraud notification process, it is determined whether or not the fraud flag is set (S27). When this flag is set (S27: YES), a fraud signal is output to the external output terminal board 9 (S28). Since the external output terminal board 9 is connected to the hall computer, the hall computer, that is, the game store side, can deal with the illegality based on the illegal signal.

  In addition to outputting an illegal signal to the external output terminal board 9 (or without outputting to the external output terminal board 9), the illegal signal is sent to the symbol control circuit 2 (via the sub-integrated circuit 3 or directly) You may display the display which alert | reports a detection on the effect symbol display part 10. FIG.

  As described above, in the ROM of the game control circuit 1, the game control area in which the game control program is stored and the fraud prevention control area in which the fraud prevention program is stored are separated. And the anti-fraud program can be easily distinguished, and the game control program can be easily inspected and checked. As a result, it can be expected to prevent the occurrence of a program creation error and the alteration of the program. Further, even if the fraud prevention program is tampered with, it is not directly related to the performance of the game. Moreover, since the surplus area 1 exists as an unused area between the game control area and the fraud prevention control area, the separation between the game control area and the fraud prevention control area is clear, and the above effects are achieved. Improve.

  In addition, the address space allocated to the RAM of the game control circuit 1 has an address space set in advance as an area 2, and a part of this area 2 is allocated as a work area for the game control program, and an anti-fraud program These work areas are assigned to areas outside the area 2. Accordingly, the work area of the anti-fraud program is separated from the work area of the RAM, and the distinction between the game control program and the anti-fraud program is clear also in the RAM work area.

  Further, as shown in FIGS. 3 and 5 to 8, the game control circuit 1 is configured so that detection signals from the magnetic sensor 7 a, the door opening switch 7 c, and the vibration sensor 7 d that are fraud detection means are input to the payout control circuit 4. A configuration in which the launch control circuit 5, the symbol control circuit 2, and the external output terminal board 9 are connected is adopted. The game control circuit 1 and the symbol control circuit 2 are provided with the relay board 6 and the sub-integrated circuit 3. However, the connection between the game control circuit 1 and the symbol control circuit 2 may be direct or indirect. Is clear.

  The payout control circuit 4 transmits to the game control circuit 1 a fraud detection signal indicating that fraud has been detected if any of the fraud detection means (magnetic sensor 7a, door opening switch 7c or vibration sensor 7d) is at a detection level. When the game control circuit 1 receives the fraud detection signal, it sets a fraud flag in the work area of the game control program. Then, when the fraud flag is set, the game control circuit 1 outputs a launch stop signal for instructing the stop of the launch to the launch control circuit 5 according to the game control program, and receives the launch stop signal. Circuit 5 stops the launcher. Further, when the fraud flag is set, the game control circuit 1 outputs a fraud signal to the external output terminal board 9 according to the fraud prevention program.

  With the configuration and operation as described above, the payout control circuit 4 performs fraud detection and the game control circuit 1 performs launch stop, so that the game control circuit 1 can be effectively used at the time of face change and control the game performance. 1 does not hinder unified control. In addition, since the fraud flag for stopping the launch uses the work area of the game control program and does not use the work area of the fraud prevention program, it is only necessary to check that the illegal action is not performed in the work area of the game control program. It's okay. Even if the data in the work area of the fraud prevention program is altered, it does not directly affect the performance of the game.

  Further, since the game control program is executed to stop firing and the fraud prevention program is output to the external output terminal board 9 (as described above, fraud detection may be displayed on the effect symbol display unit 10). The control program only needs to be checked by a security check program or the like, and even if the anti-fraud program is tampered with, it does not affect game performance.

The pachinko machine 21 shown as an example of the gaming machine in the embodiment,
A game control circuit equipped with a ROM in which a game control area for storing a game control program for controlling the progress of a game and a fraud prevention control area for storing a fraud prevention program for preventing fraud are separated;
A payout control circuit for controlling the payout of the prize body,
The payout control circuit detects a magnetic sensor for detecting a magnetic force exerted on the gaming machine from the outside, a door opening switch for detecting that the front frame is opened, or detecting that the gaming machine is vibrated. Connect one of the vibration sensors,
The game control circuit is connected to a launch control circuit, a symbol control circuit and an external connection terminal board,
If the detection signal of the magnetic sensor, door opening switch or vibration sensor is a detection level, the payout control circuit transmits a fraud detection signal indicating that to the game control circuit,
When the game control circuit receives a fraud detection signal, it sets a fraud flag in the work area of the game control program,
If the fraud flag is set, the game control circuit outputs a signal for instructing the stop of the firing according to the program of the fraud prevention control area,
In addition, it is configured to output a signal for reporting fraud to the external output terminal board according to the program of the control area for fraud prevention, and if it is a gaming machine of such a configuration,
As described above, the payout control circuit performs fraud detection, and the game control circuit performs launch stop, so that it can be used effectively at the time of face change, and it prevents the game control circuit from performing unified control over control related to game performance. Don't be. In addition, since the fraud flag for stopping the launch uses the work area of the game control program and does not use the work area of the fraud prevention program, it is only necessary to check that the illegal action is not performed in the work area of the game control program. It's okay. Even if the data in the work area of the fraud prevention program is altered, it does not directly affect the performance of the game. Furthermore, since the game control program is executed to stop the launch and the fraud prevention program is output to the external output terminal board (note that fraud detection may be displayed on the effect symbol display section), the game control program is secured. It is only necessary to check with a check program or the like, and even if the fraud prevention program is tampered with, it does not affect the performance of the game.
[Modification 1]
In the embodiment, the range of addresses 0000H to 10FFH is set as area 1, the game control program is stored in area 1, and the anti-fraud program is stored in an address outside area 1, thereby storing the game control program. Between the game control area and the anti-fraud control area in which the anti-fraud program is stored, at least the surplus of area 1 exists as an unused area, and the game control area and the anti-fraud control area are separated. But
For example, the game control area in which the game control program is stored is 0000H to 0E01H, the subsequent 0E02H to 0EFFH is the unused area, and the anti-fraud control area in which the anti-fraud program is stored is 0F00H to 1300H. The game control area and the fraud prevention control area may be separated by interposing an unused area between the game control area and the fraud prevention control area. Even in this case, it is easy to distinguish between the game control program and the fraud prevention program, and the inspection and check of the game control program is simple. As a result, it can be expected to prevent the occurrence of a program creation error and the alteration of the program. Further, even if the fraud prevention program is tampered with, it is not directly related to the performance of the game.
[Modification 2]
As shown in FIG. 9, the launch control circuit 5 may be connected to the payout control circuit 4, and the payout control circuit 4 may be connected to an external output terminal plate 9 a.

  In this case, the fraud detection process executed by the payout control circuit 4 is modified as shown in FIG. That is, the detection signal from the fraud detection means is input (S11), and it is the same until any one of the detection signals is at the detection level (S12). A signal is output to the external output terminal board 9a (S15), and a firing stop signal is output to the firing control circuit 5 (S16).

  On the other hand, the game control circuit 1 does not need to perform the processes shown in FIGS. 6 to 8, and a winning signal from the count switch is input by the fraud prevention program, for example, when the big winning opening 37 is not open, etc. The game illegality is detected, and if the illegality is detected, an illegal signal is outputted to the external output terminal board 9. The illegal signal may be output to the external output terminal board 9a via the payout control circuit 4.

  With this configuration, the payout control circuit 4 detects fraud by the fraud detection means (the magnetic sensor 7a, the door opening switch 7c or the vibration sensor 7d), stops the launch, and controls the output to the external output terminal plate 9a. Therefore, the effective use at the time of face change can be further promoted. In addition, since the game control circuit 1 performs an abnormality (injustice) such as winning detection when the solenoid of the attacker is not turned on and outputs it to the external output terminal board 9, it is determined by the program as an abnormality in the progress of the game. The circuits 1 and 4 can execute a process that clearly distinguishes between the illegality and the illegality that exerts a physical action on the gaming machine.

The gaming machine shown in Modification 2 is
A game control circuit for controlling the progress of the game;
Provided with a ROM for a payout control circuit in which a payout control area for storing a payout control program for controlling the payout of prizes and a fraud prevention control area for storing a fraud prevention program for preventing fraud With a payout control circuit,
The payout control circuit detects a magnetic sensor for detecting a magnetic force exerted on the gaming machine from the outside, a door opening switch for detecting that the front frame is opened, or detecting that the gaming machine is vibrated. Connect one of the vibration sensors to the launch control circuit and the external connection terminal board,
If the detection signal of the magnetic sensor, door opening switch or vibration sensor is at a detection level, the payout control circuit outputs a signal for instructing the stop of the emission to the launch control circuit according to the program in the control area for fraud prevention. In addition, it is configured to output a signal for reporting fraud to the external output terminal board according to the program of the control area for fraud prevention, and if it is a gaming machine of such configuration,
As described above, the payout control circuit detects fraudulent acts by fraud detection means (magnetic sensor, door opening switch or vibration sensor), and stops firing and controls output to the external output terminal board. It can be used further. In addition, since the game control circuit performs an abnormality such as a winning detection when the solenoid of the attacker is not turned on and outputs it to the external output terminal board, it is an illegality that is judged as an abnormality in the progress of the game by the program. And the game control circuit and the payout control circuit can execute a process that clearly distinguishes between the game and the fraud that exerts a physical action on the gaming machine (the fraud that is determined to be abnormal if the sensor or the like senses (ON)). .

In the above gaming machine, “a game control area storing a game control program for controlling the progress of the game and a fraud prevention control area storing a fraud prevention program for preventing fraud are separated. It goes without saying that a “game control circuit equipped with a ROM” can be adopted.
[Others]
In the embodiment and the modification, the magnetic sensor 7a, the door opening switch 7c, and the vibration sensor 7d are provided as the fraud detection means. However, at least one sensor that functions as the fraud detection means is sufficient.

In the embodiment, a game control circuit equipped with a ROM storing a game control program and a fraud prevention program has been described.
In the ROM for the payout control circuit storing the payout control program for controlling the payout of the prize and the fraud prevention program for preventing fraud, the payout control area storing the payout control program as in the embodiment. And the anti-fraud control area storing the anti-fraud program can be employed.

  Then, the payout control program and the fraud prevention program can be easily distinguished, and the payout control program can be easily inspected and checked. As a result, it can be expected to prevent program creation mistakes and program tampering, and even if the anti-fraud program is tampered with, it is not directly related to game performance. The same effect as the example can be obtained in the ROM for the payout control circuit.

  Further, in such a ROM for the payout control circuit, the payout control area is stored in a preset address space (hereinafter referred to as “area 1”), and the payout control program is illegal even if the area 1 is not satisfied. The prevention program can be stored outside the area 1.

Alternatively, such a ROM for the payout control circuit may be configured such that an unused area is interposed between the payout control area and the fraud prevention control area.
The payout control circuit including the payout control circuit ROM includes a ROM for the payout control circuit, a CPU that executes the payout control program and the fraud prevention program stored in the ROM, and the CPU In the payout control circuit including the RAM to be accessed, the RAM may be configured such that the work area of the payout control program and the work area of the fraud prevention program are separated.

  The game control circuit configured as described above has the above-described effect because it includes the above-described payout control circuit ROM. Further, since the RAM has a configuration in which the work area of the payout control program and the work area of the fraud prevention program are separated, the distinction between the payout control program and the fraud prevention program is also clear in the RAM work area. .

  In the gaming control circuit configured as described above, in the RAM, the work area of the payout control program is stored in a preset address space (hereinafter referred to as “area 2”), and the work of the fraud prevention program is performed. The area can be outside the area 2.
