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 from first and second authentication values for authenticating itself twice to a prescribed control command and supplies it to the intermediate part 202. The intermediate part 202 authenticates the main control part 201 for the first time using the first authentication value obtained from the authentication data added to the prescribed control command, adds intermediate processing information obtained from the authentication result of the first time and the second authentication value to the prescribed control command and supplies it to the sub control part 203. The sub control part 203 authenticates the main control part 201 for the second time using the second authentication value obtained from the intermediate processing information added to the prescribed control command, and performs processing according to at least one of the authentication result of the first time obtained from the intermediate processing information and the authentication result of the second time obtained by authentication in the inside.
