DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a system for preventing unauthorized use of various game machines such as a pachinko game machine in which a game is executed in accordance with a game execution program in accordance with a player's operation.

[0002]

2. Description of the Related Art In recent years, a pachinko gaming machine, which is one of gaming machines provided with a value in accordance with a game result, has an image display unit such as an LCD (Liquid Crystal Display) disposed substantially at the center of the board surface. What is constituted is often used.
In such a pachinko gaming machine, for example, 3
One display area is formed in the horizontal direction, and a predetermined symbol is displayed in a vertically scrolled state in each display area when a hit ball wins in the starting winning opening (starting chucker). If each symbol matches a preset symbol when the symbol stops, a specific game state (so-called jackpot state) until a predetermined time has elapsed.
And the jackpot winning opening is opened. As a result, most of the hit balls are led to the jackpot winning opening, and a large amount of prize balls are paid out.

[0003] The pachinko gaming machine thus configured is:
The ROM (Res) which is arranged inside according to the operation of the player
The game proceeds according to the game execution program stored in the ad-only memory, and the three symbols match with a predetermined probability. In pachinko halls, etc., a plurality of pachinko machines are
It is connected to a central control device, and the payout state of prize balls of each pachinko gaming machine is managed.

[0004]

By the way, in a pachinko gaming machine in a pachinko hall or the like, a specific player (a so-called goto teacher) improperly modifies a regular ROM installed therein (for example, a ROM). It may be exchanged for a so-called back ROM which is set so that the probability that the three symbols coincide with each other is high, and an act of illegally receiving prize balls may be performed.

[0005] Even in such a case, if the pachinko gaming machine exchanged for the back ROM is designed to always have a high probability of jackpot regardless of who plays the game, the central control device manages the payout state of the prize balls so that it becomes illegal. It is possible to tell that the action is taking place. However, the usual back R
In the OM, a specific operation (for example, an operation such as stopping the hitting operation for a fixed time after a hitting ball has won the starting winning opening).
Unless you do, it will not be a jackpot. Therefore, when a goto who knows that it is exchanged for a back ROM plays only for a certain amount of time during the day, and the rest of the time is played by a general player, the total prize balls are paid out. No extraordinary changes occur in the state, making it difficult to identify fraud.

[0006] Such a problem is caused not only by pachinko gaming machines but also by gaming machines to which a value according to the game result is given (for example, payout of balls, coins, prizes and the like in accordance with the game result). This also occurs in various other gaming machines such as slot machines in which a game is advanced in accordance with a game execution program stored in a memory such as a ROM.

[0007] Therefore, the present invention is directed to a gaming machine to which a value is given according to a game result, which effectively prevents a game machine from proceeding according to a game execution program stored in a memory.

In this case, the read security information may be included in the transmission data of the game execution program.

Next, an example of the operation of the system for preventing unauthorized use of a gaming machine configured as described above will be described. At first,
The update process of the game execution program will be described with reference to the flowchart shown in FIG.

First, before starting operation of each pachinko gaming machine 10 in a game hall such as a pachinko hall (for example, before opening of the game hall), when the power switch of the system is turned on and the system is started, each pachinko game is started. First and second CPUs 56 and 66 of the machine 10, first and second microcomputers 6
0, 72 and the CPU 80 of the central control device 14 are ready for operation. Then, the first and second microcomputers 60,
72, the first and second program memories 58, 6
The game execution programs (control program and display program) stored in 8 are erased, and each component is initialized and set to an initial state (step ST1). The first and second program memories 5
The game execution programs stored in 8, 68 do not always need to be deleted.

Next, the game execution program transmitted from the central control device 16 is received by the first microcomputer 60 (step ST3). That is, when each pachinko gaming machine 10 is set to the initial state, the game execution program in the recording medium CD inserted into the insertion slot 38 of the central control device 16 is read, and the read game execution program is used as the security information. Is transmitted to each of the pachinko gaming machines 10, and accordingly, each of the pachinko gaming machines 10 receives the game execution program. The game execution program in the recording medium CD is
The game has been scrambled and encrypted, and the game execution program is transmitted in this encrypted state. For this reason, the first microcomputer 60
Release means 60 after receiving the game execution program.
In step 3, the encryption is released (decrypted).

As described above, by encrypting the game execution program in the recording medium, it is difficult to modify the recording medium CD illegally. The payout of prize balls can be prevented from being performed. Also, the recording medium C
By encrypting the game execution program in D, unauthorized modification of the application program in the central control unit 14 becomes difficult, and the application program is exchanged with a recording medium that has been illegally modified by a master such as Goto. It is possible to prevent the payout act from being performed.

Next, the display program of the received game execution program is transferred to the second microcomputer 72 by the first microcomputer 60 (step ST5). The transferred display program is received by the second microcomputer 72 and written into the second program memory 68 (step ST7). That is, the display program in the second program memory 68 is updated. At this stage, the display unit 50 is controlled by the second microcomputer 7.
From the second CPU 66 to the second CPU 66 so that the second C
PU 66 is in a standby state in the game mode.

Next, the control program of the received game execution program together with the security information is stored in the first program memory 58 by the first microcomputer 60.
(Step ST9). That is, the control program in the first program memory 58 is updated together with the security information. At this stage, the control of the main unit 48 is controlled by the first microcomputer 60 from the first CP.
The process moves to U56, whereby the first CPU 56 enters a standby state in the game mode.

The pachinko gaming machine 10 having completed the updating process of the game execution program as described above functions as follows. That is, the pachinko gaming machine 1
When the operation of the handle 18 is started, the lower tray 22 is operated.
The pachinko balls stored therein are sequentially driven into the board 12 via the guide rails 20. When the hit ball wins the start winning opening 30, each symbol displayed on the image display unit 28 is scrolled, and when the symbols match when the scrolling is stopped after a certain period of time, the jackpot winning opening. 32 opens. In this state, the board 18
Most of the balls hit into the jackpot win prize port 32, and a large number of prize balls are discharged to the upper tray 20. Further, when the hit ball wins a prize hole other than the start prize hole 30, a predetermined number of prize balls corresponding to the prize hole are placed on the upper receiving tray 2.
Discharged to zero.

It should be noted that a hit ball that does not win any of the winning openings is confiscated in the out opening 34. When a prize ball is paid out, the number-of-payouts data is transmitted to the central controller 16 at a predetermined timing (every fixed time or every time a prize ball is paid out) together with the time.
In the central control unit 16, the received payout number data is stored in the memory 82 for each pachinko gaming machine 10, and the payout number and payout time of the prize balls during the operation time, the total value of the payout number, and the like are printed as necessary. It can be out.

Next, a fraud monitoring operation during operation of the pachinko gaming machine 10 will be described with reference to a flowchart shown in FIG. In this case, it is assumed that the security information transmitted from the central control device 16 is stored in each pachinko gaming machine 10. First, the central controller 16
A request signal for security information generated by the request signal generating means 803 is transmitted to each pachinko gaming machine 10 (step ST51). In each pachinko gaming machine 10,
In response to receiving the request signal, the security information is transmitted to central controller 16 (step ST53). That is, when the request signal is received by the receiving means 561 of each pachinko gaming machine 10, the security information stored in the first program memory 58 is read by the reading means 562 and transmitted to the central controller 16 by the transmitting means 563. . Each pachinko gaming machine 10 transmits identification information recorded in the first program memory 58 and the like at the same time as security information.

Next, central controller 16 determines whether or not the received security information matches the transmitted security information (step ST55). That is, in the central controller 16, the security information transmitted from each pachinko gaming machine 10 is received by the receiving means 804, and the received security information is stored in the memory 82 transmitted to each pachinko gaming machine 10. The judgment means 805 determines whether the security information is different from the latest security information.
Is determined by If this determination is denied, the pachinko gaming machine 10 corresponding to the identification information is specified, and the management number of the pachinko gaming machine 10 is displayed on the unauthorized device display unit 43 (step ST57).

That is, if the first program memory 58 is replaced by an incorrectly modified back memory by a master such as Goto, the same security information as the updated security information is not written in the back memory ( (No security information exists.) Therefore, inconsistency with the security information stored in the memory 82 occurs, and an illegal action is found. When a misconduct is discovered, a warning means such as a buzzer or a blinking lamp is attached to each pachinko gaming machine 10 so that the warning means is activated or the pachinko ball is not fired even if the handle 18 is operated. You can do it.

When the back memory is rewritable, the control program of the back memory of the pachinko gaming machine 10 is automatically updated in the same manner as at the time of booting as soon as an illegal action is found. You can also. in this way,
When the control program or the like in the back memory is automatically updated, it is not always necessary to display the management number or the like of the pachinko gaming machine 10 in which the misconduct is performed on the unauthorized machine display unit 43. When the determination is affirmed in step ST55, the process returns to step ST51, and the subsequent operation is repeatedly executed.

The present invention is not limited to the above-described embodiment, but can adopt the following modified embodiments.

(1) In the above embodiment, when the pachinko gaming machine 10 is started before the game hall is opened, the central controller 1
6, the game execution program is transmitted to each of the pachinko gaming machines 10 and the game execution program in the internal memory is updated. May be updated periodically.

Further, for example, if a spare internal memory is connected to a regular internal memory so as to be switchable, updating is possible even when the pachinko gaming machine 10 is in use. That is, the game execution program in the spare internal memory may be updated, and the pachinko gaming machine 10 may be switched from the regular internal memory to the spare internal memory when the pachinko gaming machine 10 is not used. In this case, the switched spare internal memory becomes the subsequent regular internal memory, and the previous regular internal memory becomes the subsequent spare internal memory.

When the payout of the prize ball has not been completed because the hit ball has continuously won the winning opening, the prize data is stored in the memory.
When such information generated in connection with the progress of the game is not stored in the memory, the game execution program can be updated even while the pachinko gaming machine 10 is in use. In short, the game execution program can be updated at a predetermined time when the progress of the play of the pachinko gaming machine 10 does not hinder.

In the above embodiment, when updating the game execution program, the previously updated game execution program is erased at the time of startup. For example, when the game hall is closed, the system power is turned off. You may make it erase when it is done.

(2) In the above embodiment, the security information is created irregularly in the central control unit 16, or information stored in advance in the memory is read irregularly and written into the game execution program. Recording medium C in which the game execution program is stored.
D may be written. In this case, the content of the security information is fixed, but even in this case, it is possible to detect an illegal act by monitoring the security information. Of course, if the security information is changed irregularly as in the above-described embodiment, it is possible to more surely detect an illegal act.

The security information is transmitted from the pachinko game machine 10 to the central control device 16 in response to a request from the central control device 16, but the security information is not requested from the central control device 16 and the pachinko game machine is transmitted. It is also possible to automatically transmit from 10 to the central control device 16 at a predetermined timing.

In monitoring fraudulent activities using the security information, the contents of the security information transmitted from the central control device 16 are used as they are. The security information may be changed under certain rules when the security information is transmitted. In this case, the contents of the security information stored in the central control device 16 are also changed at the same time under a certain regularity. Monitoring will be performed. By doing so, the confidentiality of the security information is increased, and fraudulent activity can be monitored more reliably.

In the present invention, it is not an essential requirement that the game execution program include security information.

(3) In the above embodiment, the game execution program is stored in the recording medium CD in an encrypted state by scrambling or the like, but is encrypted at the stage of transmission by the central control unit 16. It is also possible to make it a state. In this case, the CPU 80 of the central control device 16 may be provided with a function realizing unit as an encrypting unit. In this way, if the data is in an encrypted state at the stage of being stored in the recording medium CD, the recording medium CD by a master such as Goto etc.
Modification of the recording medium CD becomes difficult, and it becomes possible to prevent improper behavior due to modification of the recording medium CD. Further, if the data is encrypted at the stage of transmission, it is difficult to perform an unauthorized modification of the memory, and it is possible to prevent an illegal act.

(4) In the above embodiment, the fraud monitoring is performed by using the security information included in the game execution program. For example, the number of award balls paid out (that is, It is also possible to monitor fraudulent activities by managing the information on the value assigned accordingly (that is, managing the value assignment status). That is, since the probability of the jackpot is set to the specified value, each pachinko gaming machine 1
By managing the number of prize balls paid out within a certain time period of 0, it can be estimated whether or not fraudulent acts are being performed. In this case, the determination means 805 of the central control device 16
The added value of the number of prize balls paid out from each pachinko gaming machine 10 within a certain period of time is compared with the prescribed number of prize ball payouts (reference information) within a certain period of time, and an illegal act is performed. What is necessary is just to provide the function realization means which judges whether or not there is.

That is, each pachinko gaming machine 10 is provided with a transmitting means for transmitting information relating to a value given in accordance with the game result to the central control device 16, while the central control device 16 receives the information relating to the value. Means and receiving
A determination means for comparing the information on the received value with the reference information to determine the presence or absence of unauthorized use of the gaming machine is provided. If the number is larger than the number of payouts by a certain number or more, it can be determined that there is a possibility that an illegal act has been performed. When it is determined that there is a possibility that a fraudulent activity has been performed, the same action as in the case of monitoring the fraudulent activity using security information such as activation of alarm means may be taken.

(5) In the above embodiment, only the game execution program stored in the memory of the pachinko gaming machine 10 is updated, but the symbols displayed on the image display section 28 of the pachinko gaming machine 10 are updated. By making the change possible, the same effect as introducing a new pachinko gaming machine 10 without replacing the pachinko gaming machine 10 can be obtained, and the operating expenses can be reduced. In this case, while the image memory 70 of the pachinko gaming machine 10 is configured by a rewritable memory, the pachinko gaming machine 10 and the central control device 16 are configured to be capable of transmitting and receiving image data, and the image data read from the recording medium is stored. May be transmitted from the central controller 16 to each pachinko gaming machine 10 to update the image data in the internal memory.

The security information may be created in the central control unit, and the content may be changed irregularly each time it is created. In this case, since the security information is constantly changed, it is difficult for the goto teacher or the like to create the back memory, and it is possible to surely detect even if an illegal act is performed.

Further, the game execution program may be transmitted in an encrypted state, and after decrypting the encryption, the game execution program may be loaded into the memory of the gaming machine. In this case, if the game execution program is stored in an encrypted state on the recording medium, it becomes difficult for a goto or the like to illegally modify the recording medium on which the game execution program is stored, and the recording medium is illegally modified. Can be prevented. Also, if the data is encrypted when transmitted, it becomes difficult for the goto teacher or the like to illegally modify the internal memory of the gaming machine, and it is possible to prevent illegal acts due to the illegal modification of the internal memory.

Further, the central control device may periodically fetch information relating to a value provided in accordance with the game result from the gaming machine, and monitor the illegal use of the gaming machine from the state of providing the value. In other words, if the value is given with a certain probability, a fraud is performed when the value of the gaming machine within a certain period of time is more than a certain value by more than a reference value. It is possible to guess. When a fraudulent activity is discovered, the fraudulent activity can be effectively suppressed by activating the alarm means or disabling the use of the gaming machine.

A plurality of gaming machines having individual identification information are connected to the central processing unit, and the central processing unit transmits identification information for identifying each gaming machine when transmitting the game execution program.
You may make it transmit simultaneously . In such a case, the central processing unit can individually transmit a game execution program or the like to each gaming machine by referring to the identification information.For example, the internal memory of a specific gaming machine is When the game is exchanged, the game execution program of only the gaming machine exchanged in the back memory can be updated. As a result, fraudulent acts can be effectively prevented.

When the central processing unit determines that the security information has been illegally used in accordance with the difference determination of the security information or in accordance with the status of value addition, the corresponding gaming machine is identified by referring to the identification information, and the corresponding gaming machine is identified. A notification to the effect may be made. In this way, it is possible to reliably detect a gaming machine that is committing fraud.
