Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine for preventing illegal modification of game control contents in a gaming machine represented by a pachinko gaming machine, a coin gaming machine, a slot machine or the like.

[0002]

2. Description of the Related Art In this type of gaming machine, one generally known in the past has been disclosed in, for example, Japanese Patent Laid-Open No. 4-28.
There was one described in Japanese Patent No. 2177. In this conventional game device, a ROM storing game control contents
And a security circuit for checking whether the stored contents of the ROM are normal or not, and the ROM stores data of other game control contents in the ROM.
When a fraudulent act of substituting for M is performed, the security circuit is configured to determine that the contents stored in the ROM have changed and detect the fraudulent act.

[0003]

However, in this type of conventional game apparatus, when the security circuit itself is modified along with the replacement of the ROM, which is more extensive than the modification of the ROM. Therefore, the fraud prevention effect cannot be expected.

On the other hand, when performing the above-mentioned fraudulent acts, in order to open the board housing means for housing the game control board provided with the ROM and the security circuit, or to remove the game control board, You must first perform an action such as disconnecting the connector connected to the game control board and disconnecting the connection state between the game control board and other electric equipment. If a control board monitoring means is provided for monitoring such a case, it is possible to deal with large-scale illegal modification beyond the above-mentioned modification of the ROM.

However, even with such a configuration,
When the control board monitoring means monitors the game control board and the function stopping means stops the control function of only the game control board, the control functions of the control boards other than the game control board are not stopped. Therefore, if the control function of the game control board can be recovered by some illegal method, the entire control function is also recovered.

Further, there is a possibility that the other control boards that carry out control other than the game control by the game control board may be tampered with, and the control board monitoring means may prevent the other control board from being tampered with. When monitoring and the function stopping means stops the control function of only the other control board, the control function of the game control board is not stopped. Therefore, also in this case, if the control function of the other control board can be recovered by some illegal method, the entire control function is also recovered.

In summary, in the case of the independent board function stop system in which the control operation function of only the control board in which an abnormality has been detected by the control board monitoring means is detected by the control board monitoring means, that function is stopped. If it is possible to recover the function of only the control board that has stopped by some method, the security is broken and fraudulent acts are allowed, and the vulnerability of the security function cannot be denied.

Therefore, the present invention has been conceived in view of such circumstances, and an object thereof is to overcome the weakness of the security function in the case of the single substrate function stop system described above and to provide a higher security function. An object is to provide a game device.

OM210, data input circuit 211, and data output circuit 2
The jackpot occurrence probability data stored in the EEPROM 210 is input to the game control microcomputer 200 via the data input circuit 211 when the power of the pachinko gaming machine 1 is turned on. The input probability data is the I / O port 204, the CPU 201.
It is loaded into the RAM 203 via. This probability data is slightly higher than the first probability data (setting 1).
And moderate second probability data (setting 2) and slightly lower third
There are three types of probability data (setting 3) and any one of them is stored in the EEPROM 204.

Assuming that the probability data loaded in the RAM 203 is the first probability data (setting 1), the case where the probability setting switch 88 is operated in that state will be described. The probability setting switch 88 can be switched between three positions of a normal position (normal mode), a setting position (setting mode), and a confirmation position (confirmation mode), provided that the power is turned on at the confirmation position. If the normal mode is operated once in the setting mode, the RAM
CPU 20 out of the probability data loaded in 203
The first probability data (setting 1) of the data specified in 1 is updated to the second probability data (setting 2). In that state, when the probability setting switch 88 is again operated from the normal mode to the setting mode, the second probability data (setting 2) loaded in the RAM 203 becomes the third probability data (setting 3). Will be updated. In this state, when the probability setting switch 88 is operated from the normal mode to the setting mode, the third value loaded in the RAM 203
Probability data (setting 3) is the first probability data (setting 1)
Will be updated. Then, every time the probability data is updated, the big hit occurrence probability data stored in the EEPROM 210 is updated. Data confirmed, E at present
Probability data stored in EPROM 210 is RAM
The game control is carried out by loading the data in 203 and using the loaded probability data. If the probability setting switch 88 is in the normal mode when the power is turned on, the probability data cannot be rewritten by operating the probability setting switch 88. Like this embodiment, the probability data is EEPRO.
Since the memory is held by M210, it is possible to flexibly deal with the increase and decrease of the set value of the probability as compared with the mechanical memory holding, and in particular, the backup power supply is required as compared with the case of storing in the RAM or the like. There is an advantage of not doing it, and it becomes advantageous when the period for holding the memory becomes long. In addition, the probability setting means including the probability setting switch 88 and the like, instead of being provided in each pachinko gaming machine,

The probability variation information is information indicating that the probability variation state has occurred, when the probability variation state occurs due to the predetermined special display result of the variable display device 33. The effective start winning information is information indicating the number of starting winnings that are effectively used for the variable display of the variable display device 33 among the starting winning balls that have won the starting winning opening 34. As described above, since the upper limit value of the memory for winning the start prize is set to "4", even if the pachinko ball exceeds the upper limit value and wins the starting winning opening 30, the excess winning prize for start is ignored. The number of start winnings actually used for variable display of the variable display device 33 after subtracting the ignored number of starting winnings is output to the hall management computer as valid start winning information.

(1) In the surveillance system (surveillance equipment) shown in FIG. 3, a storage medium, which is an IC card, in which predetermined access permission information is stored, and the storage information of the storage medium is read and the level corresponding to the storage information is read. It includes access permission means (241 to 244) for permitting access for maintenance work of the control board of the gaming machine within the range. Also,
The storage medium is composed of a plurality of storage mediums storing access permission information of different levels.

(2) The substrate container shown in FIG. 6 has a transparent portion (101C, 101C,
101B). Further, a current is caused to flow between the unsealing portion (101C) capable of unsealing the substrate container and the unsealing portion and the other portion (100), and the interruption of the current due to the unsealing of the unsealing portion is detected to accommodate the substrate. It is configured to detect that the body has been opened.

(3) The EEPROM 202 shown in FIG.
252 or the EEPROM of the display control board is composed of a RAM as an example of a volatile memory, and the control data such as a control program stored by shutting off the power supply to the RAM by the function of the function stop means of each board is stored. It may be deleted. That is, the function stopping means included in the game device of the present invention stops the function by erasing the stored data of the erasable control data storage means such as the EEPROM or RAM. As a result, if fraud is applied and the stored data in the control data storage means is erased,
Program analysis by a third party can also be prevented, and the function cannot be restored unless the control data is rewritten from the beginning (such as when the power is turned on again), and thus the fraud prevention effect can be enhanced. The function stopping means may be so-called overwriting for writing random data without erasing the data stored in the control data storage means.

Since the connection information described with reference to FIG. 7 is composed of predetermined signal information such as a pulse having a predetermined pattern, the fraud prevention effect is enhanced.

Further, the substrate monitoring means 225, 225
A and 225B may be provided outside the gaming machine. In that case, the gaming machine of the present invention is configured by the board monitoring means and the gaming machine provided outside.
