Description of the Related Art Conventionally, a pachinko gaming machine stores a program for controlling the operation of the pachinko gaming machine in a storage means, and the central processing unit executes the control program to generate a hit and pay out a prize ball. , The opening operation of the special winning opening and the operating winning opening, the lighting of the lighting device, the operation of the audio output device, and the like. As described above, since the operation of the pachinko gaming machine is controlled by the control program, it is possible to increase the frequency of hitting, for example, by illegally changing the contents of the control program.
Therefore, if the control program is illegally changed,
It is required to detect the change early.

FIG. 11 is a view for explaining processing of a main control unit for controlling the operation of a conventional pachinko gaming machine. FIG. 11A shows a configuration of the main control unit, and FIG. 11B is a flowchart showing a processing procedure executed by the main control unit.
The main control unit 91 includes a ROM 121 and a RAM 122, and the ROM 121 stores a game machine control program verification code 121a, a game machine control program verification processing program 121b, and a game machine control program 121c. Although not shown, the main controller 9
1 is connected to a prize ball detection sensor, a special symbol display device, a prize ball payout device, a special electric accessory, a voice output device, a lighting device, etc., and outputs a signal for controlling these according to the gaming machine control program 121c. I do.

The value of the game machine control program verification code 121a stored in the ROM 121 is a value calculated in advance by a predetermined calculation based on the contents of the regular game machine control program 121c. The game machine control program verification program 121b is a game machine program verification code value calculated by executing the predetermined operation again based on the game machine control program 121c stored in the ROM 121 at the time of verification, and stored in the ROM 121. This is a processing program for verifying whether or not the value of the existing gaming machine control program verification code 121a matches.

When the power is turned on, a value obtained by executing the predetermined calculation based on the gaming machine control program 121c according to the gaming machine control program verification program 121b and a gaming machine control program verification code stored in the ROM 121 It is verified whether the value of 121a matches (S401). Then, if they match, there is no abnormality (S402 "YES"),
The processing shifts to a gaming machine control process (S403) executed according to the gaming machine control program 121c. Subsequently, a reset signal generation means (not shown) repeatedly executes the gaming machine control process based on a periodically generated reset signal ("YES" in S404, S403). On the other hand, if they do not match, it is abnormal (S402 "NO"), and the process is stopped without shifting to the gaming machine control process (S405).

Therefore, if the stored game machine control program 121c is changed to another game machine control program 121c 'and the stored game machine control program verification code 121a is not changed, the changed game machine control program 121c is changed. It is detected that the gaming machine control program has been changed because the value of the gaming machine control program verification code 121a obtained from the gaming machine control program 121c 'and the value of the gaming machine control program verification code 121a stored in the ROM 121 do not match. Then, even if the power is turned on, the changed gaming machine control program 121c 'is not executed, and the operation of the gaming machine is stopped. Then, the game arcade manager was able to know the change of the game machine control program by stopping the operation of the game machine.

When a game ball passes through the gate, the normal symbol display device 34 is controlled to be started based on these detection signals.

FIG. 7 is a diagram showing the configuration of the main control board in more detail. The main control board 91 includes a central processing unit (hereinafter, referred to as a CPU) 99, a ROM 121, and a RAM 12.
2. It has a first timer 123, a second timer 124, and an interrupt controller 125. The ROM 121 stores a game machine control program verification code 121a, a game machine control program verification program 121b, a game machine control program 121c, an ID code 121d, and an ID code transmission program 121e.

The interrupt controller 125 is interposed between the first timer 123, the second timer 124, the external connection terminal 97 and the CPU 99 as shown in the figure. The first timer 123 outputs a pulse signal to the interrupt controller 125 at approximately 2 millisecond intervals. The second timer outputs a pulse signal to the interrupt controller 125 at 5-minute intervals. In addition, the external connection terminal 9
7, an ID code request signal and a game machine control program verification command signal are transmitted to the interrupt controller 125 as necessary.

The interrupt controller 125 identifies a signal received from the first timer 123, the second timer 124 or the external connection terminal 97, and sends an interrupt request signal corresponding to an interrupt process to be executed to the CPU 99. Send Specifically, the interrupt controller 125 transmits a first interrupt request signal to the CPU 99 when receiving a pulse signal from the first timer 123, and transmits a first interrupt request signal to the CPU 99 when receiving a pulse signal from the second timer 124. A second interrupt request signal is output to the CPU 99, and a third interrupt signal is output to the CPU 99 after a lapse of a predetermined time. That is, the pulse signal output by the second timer 124 is a game machine control program verification command signal and is also an ID code transmission command signal. The external connection terminal 97
Outputs a second interrupt request signal to the CPU 99 when receiving a game machine control program verification command signal from the CPU, and outputs a third interrupt request signal to the CPU 99 when an ID code request signal is received from the external connection terminal 97. Send.

When the CPU 99 receives the first interrupt request signal, it executes processing in accordance with the gaming machine control program 121c, and when it receives the second interrupt request signal, it executes processing in accordance with the gaming machine control program verification program 121b. Then, when the third interrupt request signal is received, the process is performed according to the ID code transmission program 121e. Further, when starting execution of the program corresponding to the interrupt request signal, the CPU 99 interrupts the process to be executed at that time and stores data relating to the interrupted process. The process returns to the process interrupted when the program is executed.

FIG. 8 is a flowchart showing a processing procedure of a gaming machine control program for instructing each gaming operation of the gaming machine. This gaming machine control program is approximately 2.0
The reset is periodically activated by the first interrupt request signal output from the interrupt controller 125 in response to the pulse signal output from the first timer at millisecond intervals, and the game ball is moved to a predetermined winning opening. It operates based on a detection signal for detecting a drop or a detection signal accompanying the occurrence of a predetermined game situation.

When the program is started, it is first determined whether or not the value of a predetermined area of the RAM 122 provided on the main control board 91 is "5AH" (S101). When the power is turned on, a random value other than “5AH” is set in this predetermined area. Therefore, it is determined that the power is turned on (“NO” in S101), and “5AH” is stored in this predetermined area and the RAM 122 Initialization of the RAM 122 is performed by writing an initial value to each work area (S12).
0). If the value set in S120 is "5AH" (S101 "YES"), it is determined that the power is not turned on, and the RAM 122 is not initialized, and a series of processing described below is performed. Execute.

First, an update process (S103) of the random number A used for determining the hit of the special symbol display device 2 is performed, and then a special symbol including a random number for selecting a fixed symbol or a reach variation mode is performed. The random number used for controlling the fluctuating operation of the symbol display device 2 and the other random number update process for performing the control process regarding the symbol displayed on the ordinary symbol display device 34 (S104). Fraud detection processing for detecting and processing (S105), determining a detection signal issued from a switch for detecting the passage of a game ball to each winning opening provided on the game board 10, and giving a control instruction according to the detection signal Switch determination processing (S10)
6) is performed respectively.

Then, a special symbol control process (S108) for controlling the special symbol display device 2 is executed according to the game situation. Specifically, the value of each random number including the random number A is extracted and stored for the number of times of winning storage in the starting winning opening 4, and according to each of the extracted values, the winning or losing of the jackpot, the jackpot symbol or a missing symbol, the reach variation. Is set, the presence / absence and the mode are set.

Then, a normal symbol control process (S109) for controlling the normal symbol display device 34 is executed in accordance with a game situation, a drive motor control process (S111) is performed, and provided on the game board 10 surface. A payout control process (S112) for controlling data relating to prize balls to be paid out in accordance with winning in each winning opening is performed. Further, a decoration control process (S113) is performed which performs a control process related to decorative lighting (decorative lamps and LEDs) which is provided on the game board 10 and is turned off when a predetermined game situation occurs.

Since data is transmitted and received by connecting each control device and control board, a part of various information (data) relating to the game situation obtained based on the above control processing and the like is controlled and processed by the information output processing. And is output (S114), and is notified to the player. The contents of the information output include a special symbol display device 2 and a normal symbol display device 3.
4 includes a process of displaying the variable number of times of storage on the normal symbol storage display LED and the special symbol storage display LED.

When a control command to be transmitted to the ordinary symbol display device 34 and the special symbol display device 2 is determined and transmitted according to the above-described control processing (S11).
5) Based on the control command, the special symbol display device 2 and the ordinary symbol display device 34 perform symbol display. Further, control processing is performed by sound effect control processing (S116) for outputting sound effects corresponding to these symbols. Then, the process returns to the process interrupted because the execution of the gaming machine control program has been started by this reset activation. (S117).

By the way, when transmitting a control command to the ordinary symbol display device 34 and the special symbol display device 2,
The normal symbol display device 34 and the special symbol display device 2 transmit a symbol control signal (strobe signal) so as to read the control command. The symbol control signal (strobe signal) is transmitted irregularly to prevent fraud. It is better to do.

Here, the reason will be described. As mentioned above,
The gaming machine control program is started approximately every 2 milliseconds,
Each time it is activated once, the jackpot determination random number A is incremented by one. That is, the value of the jackpot determination random number A periodically increases. Therefore, when the symbol control signal (strobe signal) is transmitted periodically, if the relationship between the cycle of the increase of the jackpot determination random number A and the cycle of the symbol control signal (strobe signal) is known, the symbol control signal (strobe signal) Signal), the increase timing of the jackpot determination random number A can be detected.

That is, if a means for detecting a symbol control signal (strobe signal) is improperly provided on the wiring from the main control board 91 to the ordinary symbol display device 34 and the special symbol display device 2, the timing of the increase of the jackpot determination random number A can be increased. Can be detected. If the value of the jackpot random number A is known and the value of the jackpot random number A at a certain point in time can be known by any method,
Since the state of change in the value of the jackpot determination random number A is known, a jackpot can be generated with a high probability by adjusting the falling timing of the game ball into the starting opening 4. Therefore, in order to prevent such misconduct, it is effective to transmit the symbol control signal (strobe signal) irregularly.

FIG. 9 is a flowchart showing a processing procedure of the game machine control program verification program. This program is activated when the second interrupt signal is received as described above, and is also activated when the power is turned on. First, predetermined arithmetic processing is executed based on the gaming machine control program 121c stored in the ROM 121, and the stored gaming machine control program 12c is executed.
A game machine control program verification code corresponding to 1c is calculated (S201). The correspondence between the gaming machine control program and the gaming machine control program verification code may be any relationship as long as the value of the gaming machine control program verification code is different depending on the content of the gaming machine control program. The number of bits having a value of "1" in the binary data constituting the machine control program is defined as a game machine control program verification code. That is, the predetermined calculation process is a process of calculating the number of bits having a value of "1" in the binary data constituting the gaming machine control program.

Subsequently, the game machine control program verification code 121a stored in the ROM 121 is read (S2).
02). Then, the value of the program verification code calculated in the processing step S201 is compared with the value of the program verification code 121a read in the processing step S202, and if both values are equal (S203 "YES"), the gaming machine The process returns to the process interrupted by the activation of the control program verification program (S204). on the other hand,
If the two values are not equal, the processing of the CPU 99 is stopped there (S205).

Therefore, if the game machine control program 121c stored in the ROM 121 is not changed when the game machine control program verification processing is executed, the game machine continues to operate. On the other hand, the ROM 121
Has been changed to another gaming machine control program 121c ', the gaming machine control program 1c whose content has been changed.
The game machine control program verification code calculated on the basis of the game machine control program verification code 121d no longer matches the game machine control program verification code 121d stored in the ROM 121.
Is stopped, the operation of the pachinko gaming machine is stopped, and subsequent games cannot be continued. Then, the amusement arcade manager can know that the contents of the ROM 121 have been changed by discovering that the operation of the pachinko gaming machine has stopped.

FIG. 10 is a flowchart showing the processing procedure of the ID code transmission program stored in the ROM 121. This program is activated when the CPU 99 receives the third interrupt signal as described above. First, an ID code 121d stored in a predetermined area of the ROM 121 is read (S301). continue,
The read ID code 121d is transferred to the external connection terminal 97.
(S302), and returns to the process interrupted by the activation of the ID code transmission program (S303).

Therefore, when the ROM 121 has not been replaced, the correct ID code 121d is transmitted.
On the other hand, when the ROM 121c is replaced, the person who illegally replaces the ROM 121 does not know the correct ID code 121d of the ROM before replacement, and the ROM 121 'after the illegal replacement is replaced with the ID code 121d'. Even if it has a function of transmitting an ID code in the same manner as the original ROM 121,
The ID code 121d ′ of the pachinko gaming machine is different from that before the exchange, and the correct ID of the original ROM 121 of the pachinko gaming machine is used.
An ID code 121d ′ different from the code 121d is transmitted to the game hall management device 300 via the external connection terminal 97. Therefore, in the gaming arcade management apparatus 300 that has received the ID code 121d ', it is possible to detect that the ROM 121 has been replaced by checking the ID code 121d with the correct ID code 121d for the pachinko gaming machine.

If the ID code is not stored in the replaced ROM 121 'or the replaced ROM 121'
Does not have an ID code transmission function, no ID code is transmitted. Therefore, the game hall management device 30
0 indicates that the ID code is not received even if a predetermined time has passed since the transmission of the ID code request signal, and the ROM 121
Can be detected.

According to the pachinko gaming machine configured as described above, the CPU 99 executes the gaming machine control program 121c every two milliseconds. Then, every five minutes, it is verified whether or not the gaming machine control program 121c stored in the ROM 121 at that time is a legitimate one, and the ID code 121d stored in the ROM 121 at that time is converted into a game center management device. Send to 300. Further, when the game machine receives a game machine control program verification command signal from the game arcade management device 300, the ROM 121
Of the gaming machine control program 121c stored in the game machine management device 300 is verified.
When the ID code request signal is received from the
The ID code 121d stored in 121 is transmitted to the game arcade management device 300.

Therefore, when no wrongdoing is performed, the normal operation is continued according to the regular game machine control program 121c. On the other hand, the gaming machine control program 121c
Is changed within 5 minutes at most, and if ROM 121 is replaced,
Since the exchange is detected outside the pachinko gaming machine within minutes, the illegally changed gaming machine control program 121
It is possible to prevent the gaming machine control program stored in c 'or the ROM 121' that has been illegally replaced from being executed for a long time.

Further, a game machine control program verification process can be executed at a desired time by a command signal from the game arcade management device 300. Since the ID code can be transmitted at a desired time according to the ID request signal from the game arcade management device 300, the exchange of the ROM 121 can be determined at a desired timing in the game arcade management device 300.

Further, if the pulse output cycle of the second timer is shortened, the ID code transmission processing and the game machine control program verification processing are executed more frequently, so that a program change or illegal ROM reading is performed. When an illegal act such as exchange is performed, it is possible to more quickly detect that the illegal act is performed.

Alternatively, the above embodiment may be modified as follows with respect to the execution of the game machine control program verification processing. The game machine control program verification process is not started by a periodic pulse signal output from the second timer or an interrupt signal based on an external game machine control program verification process execution command signal. The program verification process may be modified so as to be repeatedly executed.

More specifically, the CPU 99 repeatedly executes the game machine control program verification process while simultaneously executing the first game machine control program verification process.
If the game machine control program is executed by an interrupt based on a pulse of a predetermined cycle from the timer of the game machine, and the game machine control program is executed preferentially with respect to the game machine control program verification processing, the game machine control program It has the effect that the game machine control program verification process can be repeatedly executed without hindering execution,
By repeatedly executing the game machine control program verification processing, it is possible to immediately detect that the game machine control program has been changed.

Although the embodiments have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the present invention is specifically illustrated as an example of a pachinko gaming machine in which a special winning opening is repeatedly opened a predetermined number of times when the symbol of the special symbol display device is a so-called winning symbol, It goes without saying that the pachinko gaming machine according to the present invention is not limited to such a pachinko gaming machine.

The ID code does not necessarily need to be stored in the ROM 121 storing the game machine control program, and is attached to and detached from the pachinko game machine integrally with the ROM 121 storing the game machine control program. What is necessary is just to be memorize | stored in the memory | storage means. The transmission and reception of the ID code request signal, the ID code transmission signal, or the game machine control program verification command signal between the main control board 91 and the game arcade management device 300 are not necessarily performed by wire communication means, but are performed by wireless communication means. May be performed.
