摘要

PROBLEM TO BE SOLVED: To detect fraudulence such as exchange of a main control board having a regular main control unit with a fraudulent main control board, and to reduce processing loads on a CPU constituting a peripheral part. SOLUTION: The Pachinko game machine includes the main control unit 201, an intermediate part 202 and a subordinate control part 203. The main control unit 201 adds authentication data from a first authentication value for self authentication to a waiting demonstration command, and feeds the data to the intermediate part 202. The intermediate part 202 subjects the first authentication value from the authentication data added to the waiting demonstration command and a second authentication value for authenticating the main control unit 201 or intermediate part 202 to an intermediate processing, adds the intermediate processed information acquired by the intermediate processing to the waiting demonstration command, and feeds the intermediate processed information to the subordinate control part 203. The subordinate control part 203 authenticates the main control unit 201 or intermediate part 202 using the first and second authentication values acquired from the intermediate processed information added to the waiting demonstration command, and executes a processing according at least to one of the acquired results of the two times of authentication.
