Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, a server and a program.

[0002]

2. Description of the Related Art In the pachinko industry, the fan population has continued to grow and is now said to be 20 million or 30 million.

However, the so-called goto act continues to increase behind such prosperity. What is Goto?
"Acts that cause the table to malfunction and illegally throw out balls."

When a goto act is performed, the goto master will overtake what is originally received by a general customer as an illegal act, the general customer is often defeated, and finally the customer who continues to lose is a pachinko. It will cause separation.

The origin of Goto acts can be traced back to Genesis of Pachinko. Initially, it was the acquisition of a salesclerk, who had the ball thrown out from the back of the pachinko machine. After that, as pachinko game machines evolve, so does the tricks of goto action. For example, magnets, hits, and piano wires. Among them, what is commonly used today is a so-called illegal ROM attachment method.

[0006] Here, the ROM stores a program for determining a big hit, and is a portion corresponding to the heart of a pachinko gaming machine.

On the other hand, the illegal ROM is a program in which a big hit as soon as a particular hit is performed is stored.
By attaching to the main control board of the pachinko game machine, the jackpot is made continuous and many balls are acquired. In order to attach this illegal ROM to a pachinko gaming machine, it is necessary to open the front panel. Therefore, a player performing a goto act may steal the eyes of a clerk to pry open the front panel or sneak into the hall at midnight. Although it is necessary to prepare a ROM, a method of purchasing a salesclerk and secretly preparing it may be used.

Various inventions have been made so far in order to prevent the installation of an illegal ROM. For example, a sensor for detecting that the cover of the main storage device has been removed is provided, or an individual identification number is assigned to the main storage device, etc., and the monitoring system electrically reads the identification number to detect the presence or absence of replacement. There are such things. There are also some inventions in which a game is not played or prize ball processing is not performed by using a password like a password that is known only to a specific person.

As a method using a password like this, for example, Japanese Patent Application Laid-Open No. 10-192534 discloses an invention of a device for preventing unauthorized modification of a gaming machine.

The pachinko gaming machine of the present invention collates the identification value of the non-volatile storage means with the identification value of the ROM and, if they do not match, disables the game. Further, the personal identification number of the non-volatile storage means and the personal identification number re-input by the personal identification number setting means are collated with each other, and only when they coincide with each other, initialization is performed so that the game can be played.

Further, Japanese Unexamined Patent Publication No. 8-155112 discloses an invention of a fraud prevention device for a gaming machine.

In the pachinko gaming machine of the present invention, the key information (password, symbol string, etc.) recorded in the key information recording means when the power supply from the control board or the game control section is cut off.
Is erased, and thereby, illegal exchange of the control board is detected, and prize ball processing is not performed.

[0013]

However, in the gaming machine as described in Japanese Patent Laid-Open No. 10-192534, it is possible to input an arbitrary number in the personal identification number setting means. When the ROM is installed, it is impossible to prevent goto.

Further, in the gaming machine as described in Japanese Patent Laid-Open No. 8-155112, in addition to the normal device, another device such as key information recording means and key information monitoring means is required,
It is necessary to review the structure of the gaming machine itself. Therefore, it becomes very expensive.

Further, these inventions are inventions focused on a method of coping with the case where the ROM is exchanged, and in such a case, they have some effect. However, it is difficult to say that ROM replacement is fundamentally prevented because ROM replacement cannot be prevented in advance.

The present invention has been made in view of the above points, and prevents unauthorized replacement of a ROM without setting a complicated device, and moreover, even if an unauthorized replacement is made, it is ensured. Another object of the present invention is to provide a pachinko game machine capable of preventing a game caused by an illegal ROM.

FIG. 7B shows the cover 90 being opened. When a correct password is entered, the motor 91 starts to move and the gear formed at the side end of the cover 90 meshes with the motor 91.
The cover 90 opens. The cover 90 moves to the lower part.

When the cover 90 is fully opened, it becomes as shown in FIG. 7 (c). In this state, the ROM 68 can be removed.

Next, FIG. 8 shows a state where the ROM 68 is correctly removed, and FIG. 9 shows a state where the ROM 68 is incorrectly removed.
The motor is omitted in FIGS. 8 and 9.

As shown in FIG. 7, when the password is entered correctly, the cover 90 opens and the ROM 68 can be removed properly. Then, as shown in FIG. 8, the socket 69 remains in a reusable state.

On the other hand, if the correct password is not entered, R
When the OM 68 is illegally removed, the result is as shown in FIG. That is, since the cover 90 is not opened but is pulled out forcibly, the cover 90 is in a broken state. Furthermore, ROM
Since 68 is also forcibly removed, the joint is in a cracked state. Therefore, it can be seen at a glance that it has been removed forcibly.

As described above, according to the present invention, first, the ROM 68 cannot be removed unless the password is correctly entered, which has the effect of preventing the illegal ROM from being attached. Furthermore, even if it is removed illegally, a trace remains and it can be identified at a glance, so it can be easily identified that the exchange was illegal,
This has the effect of preventing a game caused by an illegal ROM before it happens.

[Motor Drive] Next, FIG. 10 shows a flow in which the motor 91 is driven and the cover 90 is opened.

Initially, it is in a state of waiting for input (step S11). CPU66 is a game hall employee,
Password input button 23 mounted on the outside of the gaming machine
It is in the state of waiting for the password input from 0.

Next, it is judged whether or not the password is received (step S12). The CPU 66 determines whether or not the password input by the employee of the game hall or the like has been received. If it is determined that the password has been received, the process proceeds to step S13, and if it is determined that the password has not been received, the process returns to step S11 and waits for input again.

Next, it is determined whether the passwords match (step S13). The CPU 66 determines whether the password received in step S12 matches the password installed in the ROM 68. If it is determined that they match, the process proceeds to step S14, and if it is determined that they do not match, this process ends.

Next, the motor is driven (step S1).
4). The CPU 66 drives the motor through the input / output bus 64 and the interface circuit group 72. As a result, the cover 90 is opened and the ROM 68 can be removed. After this processing ends, this processing ends.

In the pachinko gaming machine 10 according to this embodiment described above, the ROM 68 is removed by the input of the password, and the cover 90 is opened by the motor 91. However, the present invention is not limited to this. If you do not enter a password, such as opening and closing with the force of a magnet, RO
Other configurations may be used as long as the M68 cannot be removed.

[Mechanism for Deleting Authentication Information] Next, how the authentication information is deleted will be described.

In a normal state, the switch 221 and the RAM 70 form a circuit via the rechargeable battery 78. As shown in FIG. 5A, the ROM 68 pushes the switch 221 and the circuit is It is a closed circuit, and current is supplied to the circuit. As a result, RAM7
The current is supplied to 0, and the stored authentication information is held.

However, as shown in FIG. 5B, RO
When M68 is removed and the switch 221 is opened, the circuit becomes an open circuit, and the current supply of the circuit is stopped. Then, the supply of current to the RAM 70 is stopped, and the authentication information is erased.

[Processing on Sub-Control Board] On the other hand, on the sub-control board, processing for transmitting a signal to the main control board to notify whether or not to start a game is performed. This process is shown in FIG.

First, it is determined whether or not the authentication information is transmitted from the main control board (step S21). CPU2
06 determines whether or not the authentication information is transmitted from the ROM 68. If it is determined that the authentication information has been transmitted, the process proceeds to step S22, and if it is determined that the authentication information has not been transmitted, this subroutine is immediately ended.

Next, it is determined whether the authentication information matches (step S22). When the CPU 206 determines that the authentication information mounted on the sub-control board and the authentication information transmitted from the ROM 68 match, step S is performed.
If it is determined that they do not match, the process proceeds to step S23.

In step S23, a start disapproval signal is transmitted. Since the authentication information does not match, the CPU 206 determines that the R
When it is determined that the OM 68 may have been removed, a signal indicating that the start of the game is not permitted is transmitted to the main control board.
As a result, the game is not started. After finishing this processing, this processing is finished.

In step S24, a start permission signal is transmitted. Since the CPU 206 has the same authentication information,
It is determined that the legitimate ROM 68 is attached, and a signal indicating that the game is permitted is transmitted to the main control board. As a result, the game is started. After finishing this processing, this processing is finished.

Steps S12 to S14 described above
By performing the processing of "removal preventing means for preventing the main storage device mounted on the main control board from being removed, and information for canceling the removal preventing function of the removal preventing means are input. The information input means, and the collation means for collating the information input by the information input means with a password for canceling the removal prevention of the removal prevention means, and the removal prevention means being released. And a detection unit for detecting that the main storage unit has been removed, and an authentication information deletion unit for deleting the authentication information stored in the main storage unit when the detection unit detects the unit. Therefore, the main storage device mounted on the main control board cannot be easily removed. That is, in order to remove the main memory device mounted on the main control board, the person who intends to perform the action must use the input means to input the correct password and release the removal prevention means. . If the main storage device is removed without performing such cancellation, the authentication information stored in the main storage device from the sub control board side to the main control board when the power of the game machine is turned on. However, since the authentication information is deleted, it is detected that the main storage device is different from the one normally used.
It is possible to prevent the fraudulent acts that were conventionally performed.

In the embodiment described above, the pachinko gaming machine is used as the "gaming machine", but the present invention is not limited to this, and the gaming state is determined by an internal lottery such as a pachislot gaming machine. Other types of gaming machines may be used as long as they are available.

[0108]

According to the present invention, "the removal preventing means for preventing the main storage device mounted on the main control board from being removed, and the removal preventing function of the removal preventing means are canceled. An information input unit for inputting information, a check unit for checking the information input by the information input unit and a password for canceling the removal prevention of the removal prevention unit, and the removal prevention unit. Detecting means for detecting that the main storage device has been removed without being released, and authentication information erasing means for erasing the authentication information stored in the main storage device when the detection means detects it. Since it has "and," it becomes impossible to easily remove the main memory device mounted on the main control board, and even if the main memory device is removed without performing such release,
Since it is detected that the main storage device is different from the one normally used, it is possible to prevent the fraudulent act which has been conventionally performed.
