Data stored in the collation judgment circuit 3 or the gaming machine information input circuit 4 when transmitting from the communication chip 2 is encrypted based on a unique key code K _i in the first encryption and decryption circuit 5, the communication circuit 8 Is transmitted to the host computer 14 via the central terminal board 12 on the way. The encrypted data received by the communication circuit 16 of the host computer 14 is
A unique key code K _i corresponding to the communication chip 2 of a predetermined base address is taken out from the unique key code storing memory 20, decoded based on the unique key code K _i is performed,
The decrypted data is stored in the determination result / game machine information storage memory 21 in order of each machine. The gaming machine information stored in the determination result / gaming machine information storage memory 21 may be mainly used by the pachinko hall, and the information on the determination result may be obtained by a third party inspection organization or the like who is in a position to prevent fraud. Can be monitored, and illegal control of the gaming machine can be monitored for all the units in the hall.

The memory used in this embodiment is EEP.
It is preferable to use a nonvolatile memory such as a ROM and a flash memory. In the present embodiment, the transmission and reception of the unique key code is performed after encryption, but the present invention is not limited to this, and the transmission may be performed as it is. Further, the second encryption / decryption circuit and the third encryption / decryption circuit are configured by different components, but the present invention is not limited to this, and the same encryption / decryption circuit may be used. Furthermore, in the present embodiment, the case where the communication chip for collation determination was mounted separately from the microcomputer chip for gaming machine control was described, but the circuit portion of the communication chip for collation determination was directly incorporated in the microcomputer chip. May be used.

[0019]

Centralized management becomes possible for the side and third party inspection organizations. As a result, the illegal check of the gaming machine can be efficiently performed. Also, when performing unified management, even if various information is accessed by a third party on the way before it is input to the host,
Because it is encrypted so that it cannot be read easily, and even if information related to encryption for one gaming machine is decrypted, the unique key code used for the encryption circuit stored in each communication chip is different. Since the decrypted information cannot be used by other gaming machines, the security is high. As a result, it is impossible to forge the microcomputer chip including the communication chip itself
