摘要

PROBLEM TO BE SOLVED: To detect such a fraudulent action that a main control board on which a regular main control part is loaded is exchanged with a fraudulent main control board, and to reduce processing loads of a CPU configuring a peripheral part.

SOLUTION: A Pachinko game machine includes the main control part 201, the intermediate part 202, and a sub control part 203. The main control part 201 adds authentication data obtained from first and second authentication values for authenticating itself twice to a big winning command and supplies it to the intermediate part 202. The intermediate part 202 authenticates the main control part 201 twice using the first and second authentication values obtained from the authentication data added to the big winning command, adds intermediate processing information obtained from first and second authentication results or the like to the big winning command and supplies it to the sub control part 203. The sub control part 203 performs processing according to at least one of the authentication results of two times obtained from the intermediate processing information added to the big winning command.
