<P>PROBLEM TO BE SOLVED: To reduce a processing burden of a CPU forming a peripheral part by sensing a fraudulent act such as replacement with a fraudulent main control board. Ž<P>SOLUTION: The game machine has a main control part 201, an intermediate part 202, and a peripheral part 203. When a control command is a waiting-for-customers demonstration command or a waiting for customers demonstration stop command, the main control part 201 adds authentication data to authenticate the main control part or data converted from the authentication data to the command and supplies it to the intermediate part 202. The intermediate part 202 carries out intermediate processing for the authentication data or data converted from the authentication data which is added to the waiting-for-customers demonstration command or the waiting-for-customers demonstration stop command, adds intermediate processing information acquired by the intermediate processing to the waiting-for-customers demonstration command or the waiting-for-customers demonstration stop command and supplies it to the peripheral part 203. The peripheral part 203 authenticates the main control part 201 by using the intermediate processing information and carries out processing corresponding to an acquired result of the authentication.
