Description

  The present invention relates to a gaming machine such as a pachinko machine or a pachislot machine (rotating type gaming machine).

In general, in a pachinko machine or pachislot machine, a random number value is acquired according to the start winning or lever operation from a random number counter that is periodically updated in the main control unit that controls the game, and the result is determined based on the random number value. If a determination is made and the determination result is a win, the game is shifted to a special game that is advantageous for winning a prize ball or coin.
On the other hand, in order to illegally allocate the special game by some malicious players, an illegal act of exchanging the main control device or its CPU with one having a high probability of winning is performed.

  In a conventional gaming machine, against unauthorized exchange of the main control device or CPU, the identification information of the CPU of the main control device of the gaming machine is collated between the data distribution server for gaming machines and the gaming machine. It has been proposed to check the validity of the machine (see, for example, Patent Document 1).

JP 2005-58306 A

However, the configuration described in Patent Document 1 is originally a configuration that changes the content of the effect displayed on the image display device or the like in response to a request from the user (player or game hall manager). When the data is transmitted from the data distribution server for gaming machines to the gaming machine, the legitimacy of the gaming machine is confirmed. Therefore, since the identification information collation process is performed only when requested by the user, the frequency of the collation process is low, and it cannot be said that it is sufficient for finding an unauthorized exchange of the main controller or CPU .

Therefore, in view of the above circumstances, the present invention has been made as an object to provide a gaming machine that can surely find an unauthorized replacement of a main control device or a CPU.

In a gaming machine in which a CPU mounted on a main control device controls a game according to a program,
The CPU of the main control device
Storage means for storing CPU-specific identification information that can be read by the instructions of the program;
After power-on of the gaming machine, reads the identification information by the instructions of the program, and output means allowed to output the identification information,
With
The main controller is
When the identification information indicating whether or not the identification information by the external device outside the gaming machine is correct is received after the output of the identification information is completed, display output and / or audio output is performed based on the result of the authentication determination. Send a notification instruction command to the sub-control device to control,
After power-on of the gaming machine gaming state when the RAM is cleared to an initial state execution, as a result of the authentication judgment, until receiving the result refers to the identification information is correct, transitions to the normal game processing in the program without the between the output end of the identification information until the predetermined time has elapsed, the identification information may come If you do not receive the results of the authenticity judgment that points to correct allowed stop CPU,
When the RAM clear is not executed after the gaming machine is turned on, regardless of whether or not the result of the authenticity determination is received, the normal game processing in the program is performed.
The sub-control device
A notification means for performing an abnormality notification when the notification instruction command based on a result indicating that the identification information is correct is not received as a result of the authenticity determination until a predetermined time elapses after power-on. Configure.

According to the invention described in claim 1, that has been configured to output to the outside of the apparatus identification information at the time of power up, early in an external device connected to the outside of the authenticity of the main control unit or CPU Judgment can be made and fraudulent activities can be detected. Therefore, damage to the game hall due to fraudulent acts can be minimized.

Since at the time of execution of the RAM cleared after power-up, configured to wait for the result of the authenticity determination by the outside of the external device, immediately not perform normal game processing after the output end of the identification information, the machine The timing at which the main game routine (ordinary game processing) is executed can be changed from the start of CPU operation (input of a reset signal) of the CPU of the main control device due to variations in processing time due to external equipment.

In addition, since the CPU is stopped when the result of the authenticity determination is not clear or when it is clear that the identification information is not correct, the game in a state where there is a possibility that fraud has been performed is disabled, and damage is caused. Can be prevented.
Also, when the result of the authenticity determination is not clear or when it is clear that the identification information is not correct, the abnormality notification is executed, so that it is possible to determine a gaming machine having a high possibility of fraud. .
In addition, when RAM clear is not executed after power-on, the process shifts to normal game processing in the program regardless of whether or not the result of authenticity determination is received. Even when a stop occurs, the game stop time is short and the player does not feel uncomfortable.

  FIG. 3 shows the electrical configuration of the pachinko machine 50. The main controller 80, the payout controller 81, the production symbol controller 82, the sub integrated controller 83 and the launch controller 84 are not shown in detail. However, each of these control devices includes a CPU, a ROM, a RAM, an input port, an output port, and the like.

In the main control device 80, the CPU executes a user program written in the mounted ROM, and executes a game according to the user program.
The CPU of main controller 80 stores unique identification information (so-called unique ID) for determining the CPU. The unique ID is stored in an area (corresponding to storage means described in claims) different from the area in the ROM where the user program is written. The unique ID can be read in response to a request from the user program. The unique ID read in this way is collated and used to find and prevent fraudulent acts such as unauthorized exchanges.
In addition to the unique ID, the CPU has an ID number that cannot be read by a user program command and is read and verified by a dedicated device.

  The main controller 80 is electrically connected to an external device 90 of the game facility outside the pachinko machine via the back wiring relay terminal board and the external connection terminal board 78. As a result, the unique ID can be transmitted from the main controller 80 to the external device 90. The external device 90 has a function of determining the authenticity of the transmitted unique ID. The main controller 80 is configured to receive the authenticity determination signal. In the present embodiment, the external device 90 is preferably configured by a hall computer (management PC). However, in addition to this, an intermediary machine (CR unit, cash unit), number of fluctuations of special figure and jackpot You may comprise with the information indicator etc. which display the frequency | count.

  The main controller 80 includes a glass frame opening SW (switch) for detecting whether the front frame (glass frame) 52 and the inner frame 70 are open via the back wiring relay terminal board and the game board relay terminal board, Inner frame opening SW, first start port SW for detecting a ball entering the first special figure start port 22A, second start port SW for detecting a ball entering the second special figure start port 22B, a normal start gate 21 Detection signals such as a normal start SW for detecting a winning ball, a count SW for detecting a winning ball 25 and a left winning port SW for detecting a winning ball to the normal winning port 24 are input.

The main control device 80 configured as described above operates according to the user program, generates various commands related to the progress of the game based on the detection signal and the like, and issues the payout control device 81 and the production relay terminal board. Commands are output to the sub-integrated control device 83 and the production symbol control device 82, which are sub-control devices, and the first and second special symbol display devices 16A and 16B, the first and second are displayed via the symbol display device relay terminal board. (2) Display control of the special figure hold number display devices 17A and 17B, the normal symbol display device 18 and the general figure hold number display device 19 is performed.
The main controller 80 controls the large winning opening solenoid that opens and closes the large winning opening 25 to open the large winning opening. In addition, it controls the operation of the universal utility solenoid that opens and closes the second special figure starting port 22B.

  The payout control device 81 detects a ball break SW that detects that the ball tank is empty, a payout SW that detects that a game ball has been paid out, and detects that the game ball storage tray is full. A detection signal such as a full SW is input. In accordance with a command sent from the main controller 80, the payout motor is operated to pay out the game ball. Further, it is electrically connected to the CR unit, and based on the loan request signal output from the CR unit based on the operation signal of the ball rental and settlement SW 57, 58 through the settlement display device 59 and the settlement request. The payout motor is operated to pay out the rental balls, and a payout completion signal is output to the CR unit. The CR unit controls the balance display of the inserted prepaid card based on the lending request by the ball lending and settlement SWs 57 and 58, the operation signal for the settlement request, and the dispensing completion signal from the dispensing control device 81.

  The firing control device 84 is input with detection signals such as a firing stop SW and a touch SW that detects that the player is touching (operating) the firing handle.

  The sub integrated control device 83 receives detection signals from the volume adjustment SW, the effect button 67, the jog dial 68, and the like. In response to a command sent from the main controller 80, the speaker 66 is driven to output sound, and various LEDs and various lamps 65 are turned on and off. Furthermore, a command for a pseudo effect for displaying a character or the like or a display form of a special symbol for a pseudo symbol is transmitted to the effect symbol control device 82.

  The effect symbol control device 82 constitutes the effect symbol display device 15 together with the LCD panel unit and the accessory unit. The production symbol control device 82 controls the display of the LCD panel according to the command sent from the sub integrated control device 83.

  FIG. 4 shows the power supply and signal system between the power supply board 87 and the main controller 80. The power supply board 87 receives the AC 24V power provided on the pachinko parlor side via the power switch 871, and the power supply generation circuit 872 supplies power to the main controller 80 and other control devices.

The full-wave 24V output in the power generation circuit 872 is input to the power supply voltage monitoring circuit 873, and the reset signal is output or canceled based on the detection result of the presence / absence of the full-wave 24V output by the power supply voltage monitoring circuit 873. That is, the power supply voltage monitoring circuit 873 determines that the full-wave 24V output is stopped if the non-output state equal to or lower than the predetermined reference voltage continues for a predetermined time, and outputs a reset signal according to the determination. On the other hand, when full wave 24V output is started, the reset signal is canceled. Here, outputting the reset signal means outputting a low level signal, and releasing means changing from a low level to a high level.
The reset signal output is output to the reset terminal of the CPU 801 through the delay circuit of the main controller 80. Thus, a predetermined delay time is provided for releasing the reset signal.

  The power supply board 87 generates a power failure signal when the power supply is interrupted, such as a power failure, based on the determination of the power supply voltage monitoring circuit 873, and outputs it to the NMI terminal of the CPU 801 of the main control device 80 and other control devices. The power failure signal is a signal that changes from a high level to a low level when the power is cut off, and the output timing is set so that the power failure signal is output before the reset signal is output. The power failure signal may be input to the CPU via the input port of the main controller 80 or another controller.

  The power supply board 87 is configured to generate a DC5V backup power supply (VBB) by a backup power supply generation circuit 878 including a capacitor, and the backup power supply (VBB) output is the main controller 80 and other controls. The data is output to the backup terminal (VBB) of the CPU 801 of the apparatus, and the stored contents of the RAM of the CPU 801 of the main control apparatus 80 and the RAM of other control apparatuses are retained during a power failure.

  The power supply board 87 also includes a RAM clear switch 874. The RAM clear switch 874 is provided to clear the contents stored in the RAM of the CPU 801 of the main control device 80 and the RAM of another control device.

  The RAM clear switch 874 is a push button type that is turned on only when pressed, and if the RAM clear switch 874 is turned on when the reset signal is released, a RAM clear signal that is a high level signal is sent to the main controller 80. And output to input ports of other control devices for a certain period of time. That is, the RAM clear signal is output only when the power is turned on when the reset signal is released. Here, the delay time from turning on the power switch 871 to releasing the reset signal is set to, for example, 100 ms. To generate the RAM clear signal, the power switch 871 is turned on while pressing the RAM clear switch 874.

  Processing when the pachinko machine 50 is turned on will be described. FIG. 5 shows a flowchart of schematic control when the CPU 801 of the main controller 80 is turned on. When the security check is completed and access to the built-in RAM is permitted (S100), the RAM clear switch is operated to check whether the RAM clear signal is on (S101), and the stored contents of the RAM before the power is shut off Whether or not the pachinko machine 50 is started from the initial state or from the state before power-off is determined based on the confirmation (S102) of whether or not the backup flag indicating that the backup is correctly performed.

  First, when the RAM clear signal is ON in the process of S101 (S101: yes), it is determined that the pachinko machine 50 is started from the initial state. If the RAM clear signal is off (S101: no) but the backup flag is off (S102: no), it is impossible to return the gaming state to before power-off because the contents of the RAM are damaged for some reason. Therefore, it is determined that the pachinko machine 50 is started from the initial state.

When the RAM is cleared to start the pachinko machine 50 from the state before the power is shut off, the unique ID is read in the subsequent process of S103, and the unique ID read in the process of S104 is further connected to the machine of the pachinko machine 50 via the external connection terminal 78. It is transmitted to the external device 90 outside. In this process, together with the unique ID, the external device 90 is notified that the power is turned on accompanied by the RAM clear. At this time, it is only necessary to be able to determine whether the power is turned on accompanied by RAM clearing or the power turned on accompanied by backup. For example, the power is turned on accompanied by RAM clear at the head or tail of the unique ID signal. It is desirable to provide a signal indicating the above.
Next, it is confirmed whether or not the transmission of the unique ID is completed (S105). If it is confirmed that the transmission is completed (S105: yes), the process proceeds to the continuation process 1 in the subsequent process of S106. In this case, a waiting time corresponding to the unique ID transmission time is provided before the process proceeds to the continuation process 1.

On the other hand, when the backup flag is ON in the process of S102 (S102: yes), it is determined that the pachinko machine 50 is returned to the state before power-off and started. At the time of backup to be started after returning to the state before the power is shut off, the unique ID is read in the subsequent process of S110, and the unique ID read in the process of S111 is transmitted to the external device 90. In this process, together with the unique ID, the external device 90 is notified that the power is turned on with backup. At that time, it is only necessary to be able to determine whether the power is turned on accompanied by RAM clear or the power turned on. For example, the fact that the power is turned on accompanied by backup at the beginning or the tail of the signal of the unique ID. It is desirable to provide a signal to indicate.
Next, it is confirmed whether or not the transmission of the unique ID has been started (S112). If the start of transmission is confirmed (S112: yes), the process proceeds to the subsequent continuation process 2 of S113. In this case, there is no waiting time for the unique ID transmission time before the process proceeds to the continuation process 2.

FIG. 6 shows the operating state of the main controller 80 when starting from the initial state by clearing the RAM and when starting from the gaming state before power-off (during backup).
As shown in FIG. 6A, when the power is turned on while operating the RAM clear switch, the reset signal rises after Ta time from power-on, and the operation of the CPU 801 of the main controller 80 starts after Tb time. After the operation, the CPU 801 permits access to the built-in RAM in the processes of S100 and S101, and when the RAM clear signal is confirmed, after reading the unique ID, transmits the unique ID to the external device 90. When the transmission of the unique ID is completed (after the time Tc has elapsed), the CPU 801 executes a continuation process.
On the other hand, at the time of backup shown in FIG. 6B, when the CPU 801 reads the unique ID after the power is turned on, transmission of the unique ID is started to the external device 90 and the continuation process is executed.
As described above, at the time of backup, there is no waiting time from the start of transmission of the unique ID to the start of the continuation process, but when the RAM is cleared, the unique ID transmission time (Tc time) from the start of transmission of the unique ID to the start of the continuation process. There is waiting time.

When the CPU 801 transmits a unique ID to the external device 90 in the processes of S104 and S111, the output of the unique ID is a serial communication of a digital signal, and a high level signal (“1” signal) and a low level signal (“0”). (Signal) output time is changed. For example, as shown in FIG. 7, the output time of the high level signal is about 100 msec, and the output time of the low level signal is about 50 msec.
In the case of 74F6 (H) with a unique ID of 2 bytes as shown in FIG. 7A, the output time (Tc time) is about 1.3 seconds, and the unique ID is 2 bytes as shown in FIG. 7B. In the case of 8881 (H), the output time (Tc time) is about 1 second. Thus, the output time of the unique ID is different for each pachinko machine. In general, your unique ID is composed of 4-byte data.

In the “continuation process 1” when the RAM is cleared, as shown in FIG. 8, it is confirmed whether or not the determination signal of the authenticity determination from the external device 90 has been received (S200). As a determination signal, only a positive determination signal in which the unique ID is correct and the main controller 80 and the CPU 801 are determined to be authentic, or the unique ID is false and the main controller 80 and the CPU 801 are invalid. Only the fraud determination signal determined to be transmitted from the external device 90 may be used, or two types of correct determination signal and fraud determination signal may be transmitted.
If the determination signal is received (S200: yes), it is confirmed whether or not the determination signal is a positive determination signal indicating that the CPU 801 is genuine (S201). If it is a positive determination signal (S201: yes), a stack setting process (S202), a RAM work area clear process (S203) is executed, and the work area is initialized (S204). Subsequently, a command for displaying an initial screen is transmitted to the effect symbol control device 82 and the effect symbol display device 15 via the sub-integrating device 83 (S205), and various LEDs, lamps, etc. are initialized to the sub-integrating device 83. A command to display the decoration is transmitted (step S206). Thereafter, normal game processing is performed.

In a normal game process , a main routine for game of the user program (this process) is executed due to a residual process that repeatedly updates the initial random number of various random numbers and an interrupt signal (INT signal) with a period of 2 ms or 4 ms. Is done. Also, a user program backup routine (backup process) is executed due to the NMI signal (power failure signal).
In the residual process, initial value random numbers such as a jackpot determination random number, a jackpot symbol determination random number, and a variation pattern determination random number are updated.
In the main routine for gaming, update processing of random numbers for determining big hits, random numbers for determining big hit symbols, random numbers for determining variation patterns, winning confirmation processing for checking the entrance of game balls to various winning ports, special charts and normal symbols Win / fail determination process for winning / raising lottery, driving of large winning mouths and electric accessories, output processing for instructing control of images, sound, lamps, etc., illegal monitoring process for monitoring illegal winnings and illegal winning balls, etc. Is executed.
In the backup routine, the RAM is backed up in order to store the game state before the power is turned off.

If the determination signal is not received in the process of S200 (S200: no), it is confirmed whether or not a predetermined waiting time set in advance has elapsed after the transmission of the unique ID to the external device 90 is terminated. (S210). If the waiting time has not elapsed (S210: no), the process returns to S200. When the waiting time has elapsed (S210: yes), or when the determination signal is not a positive determination signal in the processing of S201 (S201: no), the CPU 801 displays an indication that the CPU 801 is not regular ( A command to display the fraudulent notification on the effect symbol display device 15 or the like is transmitted (S211), and a stop process (S212) of the CPU 801 is executed. In the stop process of the CPU 801, the CPU itself does not stop, but the CPU stops the execution of the user program. When a power failure occurs and the CPU 801 receives an NMI signal (power failure signal), the CPU 801 performs a RAM backup process.
It should be noted that it is desirable to add a signal indicating that the RAM is being cleared to the fraud notification command transmitted in the process of S211 to notify the sub integrated device 83.
Further, when a positive determination signal is received (S201: yes), the CPU 801 may be configured to transmit a legitimate command to the sub integration device 83.

In the “continuation process 2” at the time of backup, as shown in FIG. 9, it is confirmed whether or not the determination signal for the authenticity determination from the external device 90 has been received (S220). As a determination signal, only a positive determination signal in which the unique ID is correct and the main controller 80 and the CPU 801 are determined to be authentic, or the unique ID is false and the main controller 80 and the CPU 801 are invalid. Only the fraud determination signal determined to be transmitted from the external device 90 may be used, or two types of correct determination signal and fraud determination signal may be transmitted.
If the determination signal is received (S220: yes), it is confirmed whether or not the determination signal is a positive determination signal indicating that the CPU 801 is genuine (S221). If the signal is a positive determination signal (S221: yes), the process at the time of power recovery is executed (step S222), and the game progress program suspended due to the occurrence of a power failure is resumed based on the information indicating the gaming state of the backed-up pachinko machine. It becomes a normal game process . Here, as in “continuation processing 1”, the main routine for game of the user program is executed due to the residual processing that repeats the updating of the initial random number of various random numbers and the interrupt signal (INT signal) with a period of 2 ms or 4 ms. The

If the determination signal is not received in the process of S220 (S220: no), it is confirmed whether or not a predetermined waiting time set in advance has elapsed after the transmission of the unique ID to the external device 90 is terminated. (S230). If the waiting time has not elapsed (S230: no), the process returns to S220. When the waiting time has elapsed (S230: yes), or when the determination signal is not a positive determination signal in the processing of S221 (S221: no), the CPU 801 displays an indication that the CPU 801 is not regular ( A command to display the fraudulent notification) on the effect symbol display device 15 or the like is transmitted (S231), and a stop process (S232) of the CPU 801 is executed. In the stop process of the CPU 801, the CPU itself does not stop, but the CPU stops the execution of the user program. When the CPU 801 receives an NMI signal (power failure signal) due to a power failure or the like, the CPU 801 performs a RAM backup process.
Note that it is desirable that the fraud notification command transmitted in the process of S231 is added with a signal indicating that it is at the time of backup to notify the sub integrated device 83.
Further, when a positive determination signal is received (S221: yes), the CPU 801 may be configured to transmit a legitimate command to the sub integration device 83.

  FIG. 10 shows the “unauthorized notification process 1” executed by the sub-integrating device 83 when the power is turned on. In this process, first, it is confirmed whether or not an unauthorized notification command is received from the main controller 80 (S300). If the command has not been received (S300: no), it is checked whether or not a predetermined waiting time that has been set in advance has elapsed since the operation of the sub integration device 83 after the pachinko machine was turned on (S301). If the waiting time has not elapsed (S301: no), the process returns to S300.

If a fraud notification command is received in the process of S300 (S300: yes), it is confirmed whether or not the received command is a notification of fraud (S302).
If it is a command for notifying fraud in the process of S302 (S302: yes), or if the waiting time has elapsed in the process of S301 (S301: yes), the CPU 801 is illegally exchanged for the effect symbol display device 15 or the like. A process of displaying (abnormality notification) that there is a possibility of being.

  According to the present embodiment, when performing unauthorized replacement of the main controller 80 or the CPU 801 of the main controller 80, it is necessary to temporarily turn off the power and turn it on again. Therefore, the unique ID unique to the CPU is output to the outside of the apparatus when the power is turned on, so that the external device 90 connected to the outside of the apparatus determines the authenticity of the unique ID at an early stage, and the main controller 80 or CPU 801. It is possible to determine whether or not the information has been exchanged illegally, and this has the effect of detecting and preventing illegal activities. Therefore, the damage to the game hall due to fraudulent acts is minimized.

  Since the unique ID output to be transmitted to the external device 90 is a digital signal serial communication and the output time of the high-level signal and the low-level signal is changed and output, the time required for transmission differs for each gaming machine. Can do. As a result, the timing at which the interrupt to the CPU 801 of the main control device 80 is permitted (the timing for executing the main routine for the user program) is changed, and the random number for determining the big hit from the start of the operation of the CPU 801 (input of the reset signal) The timing until the random number counter reaches the big hit value can be changed, and the illegal act of aiming at the big hit value after the RAM is cleared can be made difficult.

  Also, a determination signal for authenticity determination from the external device 90 is input to the main control device 80. When the RAM is cleared, the continuation processing is not performed immediately after the output of the unique ID is completed but until the determination signal is received. Is not executed, the timing at which the interrupt to the CPU 801 of the main control device 80 is permitted is changed using the variation in the processing time by the external device 90, and a random number counter such as a big hit determination random number is changed from the start of the operation of the CPU 801. The timing until the big hit value is reached can be changed, and it is possible to make it difficult to perform an illegal act aiming at the big hit value after the RAM is cleared.

The CPU 801 is configured to stop when the waiting time for waiting for the result of the authenticity determination has elapsed and the determination result is not clear or when the unique ID is clearly incorrect. The game in the state can be disabled, and the spread of damage due to fraud can be prevented.
In addition, when the authenticity is not clear or when it is clear that the unique ID is not correct, the abnormality notification is executed, so that it is possible to find and prevent fraud.

In the present embodiment, the fraud notification flag may be set when the fraud notification command is transmitted in the fraud notification command transmission processing (S211, S231) of the “continuation processing 1” and “continuation processing 2”. desirable. This is because even if the CPU 801 is stopped by the subsequent CPU stop processing (S212, S232) and the power is cut off, the fraud notification flag is stored in the backup by the NMI signal (power failure signal), and an abnormality is notified before the power is cut off. You can remember that was done.
When the fraud notification flag is set when the power is turned on again, it is desirable that the fraud notification command is retransmitted to the sub integrated device 83 so that the abnormality is notified again.

  Further, in the present embodiment, even when the CPU 801 is stopped by the CPU stop processing (S212, S232) of the “continuation processing 1” and “continuation processing 2”, When an affirmative determination is made in the positive determination signal confirmation process (S201, S221), the game is normally started up. In this case, when the fraud notification flag is set, the fraud notification flag is cleared after receiving the correct determination signal. At this time, a fraud notification command may be transmitted to the sub integrated device 83 on condition that the fraud notification flag is set. According to this, when a negative determination is made in S210 and S230 due to poor connection or contact between the pachinko machine and the external device and the CPU is stopped, there is a possibility that it may be disadvantageous to a player who is not cheating. However, if it can be recovered immediately by turning on the power again, the disadvantage can be reduced and the player can be protected.

  Next, a second embodiment of the present invention will be described. The pachinko machine according to the present embodiment is configured so as to wait for the end of transmission of the unique ID at the time of backup as well as when the RAM is cleared, and then shift to the continuation process. It is almost the same as that of the embodiment. FIG. 11 shows the control contents of the “power-on process 2” executed by the main controller 80 of the present embodiment, and the difference from the “power-on process 1” will be mainly described.

  In “power-on process 2”, at the time of backup (S122: yes), after reading the unique ID (S130) and transmitting to the external device 90 (S131), it is confirmed whether the transmission of the unique ID is completed (S132). If it is confirmed that the process has been completed (S132: yes), the process proceeds to continuation process 2 in the subsequent process of S133. In this case, a waiting time corresponding to the unique ID transmission time is provided before the process proceeds to the continuation process 2.

According to the present embodiment, although a game stop period occurs during a momentary power failure, the effects of finding and preventing fraudulent acts can be obtained as in the first embodiment. Further, in both cases of RAM clearing and pack-up, there is a waiting time for waiting for completion of transmission of a unique ID for each pachinko machine. It is possible to change the timing until the random number counter reaches the big hit value, and to prevent an illegal act aiming at the big hit value.
Similarly to the first embodiment, the fraud notification flag is set when the fraud notification command is transmitted, and the game is normally performed when the positive determination signal is confirmed by power-on after the CPU 801 is stopped. It is desirable to have a configuration to start up.

Next, a third embodiment of the present invention will be described. In the pachinko machine according to the first embodiment, during backup, the CPU 801 is stopped when the authenticity determination of the unique ID by the external device 90 is illegal. However, the main controller 80 and the CPU 801 are illegally replaced. From the point of view that the RAM is always cleared, it can be said that the backup is not illegal. Therefore, in this embodiment, the control is simplified by eliminating the stop process of the CPU 801 at the time of backup. The pachinko machine of the present embodiment has the same basic configuration as that of the first embodiment, and after the affirmative determination in S112 of “power-on process 1” (FIG. 5), as shown in FIG. The process proceeds to “continuation process 3”, the process at the time of power recovery is executed (step S240), and the game progress program suspended due to the occurrence of a power failure is resumed based on the information indicating the gaming state of the backed-up pachinko machine . Game processing . Here, similarly to the “continuation process 1”, the main routine for game of the user program is executed due to the residual process that repeats the updating of the initial random number of various random numbers and the INT signal of the 2 ms period or the 4 ms period. Also, the user program backup process is executed due to the NMI signal.

According to the present embodiment, in substantially the same manner as in the first embodiment, it is possible to obtain the effects of finding and preventing fraudulent acts, and to simplify the control processing during backup.
At the time of backup, there is no waiting time for the output of the unique ID and the waiting time for the determination signal from the external device 90, and the normal game processing is started immediately after the process of power recovery is started after the transmission of the unique ID is started (the processing of S112 in FIG. 5). Therefore, the time required from power-on to starting normal game processing can be shortened, and even if a sudden power outage (instantaneous power failure) occurs unexpectedly during the game, the game stop time is short and Don't feel uncomfortable.
Note that the processing S220, S221, and S230 to S232 related to confirmation of the unique ID authenticity determination signal executed in the “continuation processing 2” (FIG. 9) of the first embodiment are referred to as “continuation processing 3” in the present embodiment. You may make it perform in the normal game process from. By determining whether the determination signal is correct in the remaining process of the normal game process or / and in the main routine, it is possible to detect this even if there is an irregularity at the time of backup.
At this time, it is desirable that S220 and S221 be provided in the residual process, and that the process be performed before or after updating the initial random number of various random numbers, and S230 and S231 be provided in the main routine. In addition, as the processing corresponding to S232, since it becomes impossible to back up the gaming state by stopping the CPU, the winning confirmation processing of the main routine, the success / failure determination processing, etc. until the NMI signal (power failure signal) is input. It is desirable that the actual gaming stop state as the gaming machine is not executed.
Similarly to the first embodiment, the fraud notification flag is set when the fraud notification command is transmitted, and the game is normally performed when the positive determination signal is confirmed by power-on after the CPU 801 is stopped. It is desirable to have a configuration to start up.
The present embodiment may have the basic configuration of the second embodiment.

  A fourth embodiment of the present invention will be described with reference to FIGS. The pachinko machine according to the present embodiment has a configuration in which the sub integration device 83 receives a determination signal for authenticity determination of the external device 90. The abnormality notification is made when the received determination signal is a false determination signal in which the unique ID is false and the main controller 80 and the CPU 801 are determined to be unauthorized. The basic configuration of the pachinko machine is almost the same as that of the first embodiment, and the differences will be described below.

  As shown in FIG. 13, in the electrical configuration of this pachinko machine, the main controller 80 is connected to the external device 90 via the back wiring relay terminal board and the external connection terminal board 78, and a unique ID is received from the main controller 80. It is transmitted to the external device 90. On the other hand, the external device 90 is also connected to the sub-integrating device 83 via the external connection terminal board 78, and the sub-integrating device 83 receives the determination signal determined as authentic by the external device 90.

When the power of the pachinko machine is turned on, the “power-on process 1” (FIG. 5) is executed in the same manner as in the first embodiment. The process proceeds to “Process 4”. In this process, a stack setting process (S250) and a RAM work area clear process (S251) are executed to initialize the work area (S252). Next, a command for displaying an initial screen is transmitted to the effect symbol control device 82 and the effect symbol display device 15 via the sub-integrating device 83 (S253), and initial decorations for various LEDs, lamps, etc. are sent to the sub-integrating device 83. A command to display is transmitted (step S254). Thereafter, normal game processing is performed. Here, as in “continuation processing 1”, the main routine for game of the user program is executed due to the residual processing that repeats the updating of the initial random number of various random numbers and the interrupt signal (INT signal) with a period of 2 ms or 4 ms. The

  On the other hand, after the affirmative determination in S112 of “power-on process 1” (FIG. 5), as in the third embodiment, the process proceeds to “continuation process 3” at the time of backup as shown in FIG.

When the power is turned on, the sub integrated device 83 executes “unauthorized notification processing 2” shown in FIG. In the “injustice notification process 2”, first, it is confirmed whether or not a determination signal for authenticity determination has been received from the external device 90 (S310). As a determination signal, only a positive determination signal in which the unique ID is correct and the main controller 80 and the CPU 801 are determined to be authentic, or the unique ID is false and the main controller 80 and the CPU 801 are invalid. Only the fraud determination signal determined to be transmitted from the external device 90 may be used, or two types of correct determination signal and fraud determination signal may be transmitted.
If the determination signal has not been received (S310: no), it is checked whether or not a predetermined waiting time has elapsed after the sub-integrating device 83 is activated after the pachinko machine is powered on (S311). If the waiting time has not elapsed (S311: no), the process returns to S310.

If the determination signal is received in the process of S310 (S310: yes), it is confirmed whether or not the received determination signal is a fraud determination signal (S312).
If it is a fraud determination signal in the process of S312 (S312: yes), or if the waiting time has elapsed in the process of S311 (S311: yes), the CPU 801 is illegally exchanged for the effect symbol display device 15 or the like. An unauthorized notification (abnormality notification) process for displaying that there is a possibility is performed.
Note that it is desirable that the determination signal received in the process of S310 is added with a signal indicating that the RAM is being cleared or backup is informed to the sub integrated device 83.
In this case, it is necessary to notify the external device by adding a signal indicating that the RAM is being cleared or being backed up to the unique ID transmitted from the CPU 801 to the external device 90.

According to the present embodiment, as in the first embodiment, the effect of detecting and preventing fraudulent acts is exhibited, and the sub-control device (sub-integrated device 83) receives a unique ID from the external device. The determination signal that is output after the authenticity determination of whether the identification information is correct is received, and the determination signal is received by the sub-control device until a predetermined time elapses after the power is turned on. Since the abnormality notification is executed when the determination signal indicating that the identification information is incorrect is received or when the identification information is not correct, the abnormality notification can be suitably performed. Then, it is possible to indicate that there is a high possibility that the main control device 80 or the CPU 801 has been illegally replaced by the abnormality notification.
In addition, since the input destination of the signal from the external device 90 is the sub-integrating device 83 that does not affect the gaming performance of the gaming machine, it is safer against other illegal acts than when the signal is input to the main control device 80. Can be increased.
Furthermore, even if the judgment signal is not normally input due to poor contact or disconnection during a momentary power failure, the abnormality notification is executed but the gaming performance of the gaming machine is not affected, which is disadvantageous to the player. Never give. In this case, the cause can be eliminated, and the original game can be restored by turning on the power again, thereby protecting the player.

  It should be noted that the present invention is not limited to the embodiments described above, and can of course be implemented in various ways without departing from the gist of the present invention. For example, the present invention may be applied not only to pachinko machines but also to pachislot machines (rotating game machines).
