PROBLEM TO BE SOLVED: To provide a game machine capable of correctly executing peripheral control of a game. SOLUTION: This game machine is so constituted that a command output from a main control device 110 to a putout control device 111 consists of two bytes and that, when adding them for every one byte or exclusively logically adding them, the lowest-order one byte after the operation becomes FFH. A putout control device 111 adds the input command of two bytes for every one byte or exclusively logically adds them and, when the result is not FFH, determines that the command is not a normal command, invalidates the input of the command, simultaneously therewith displays a letter, "C" on a 7-segment LED 121 provided in the putout control device 111 and notifies a command error. The putout control device 111 can input the normal command alone as a valid command so as to correctly execute the putout control of the game and prevent the unregulated putout and putout by a fraud.
