PROBLEM TO BE SOLVED: To provide a game machine which can prevent the misreception of control data in a sub board by filtering out the noise of a strobe line from time to time. SOLUTION: The game machine outputs a read command to a first holding output circuit after outputting control data to a second holding output circuit by a read command output means, and outputs the clearance data of the read command by a read command clearance means in accordance with the timing of outputting a drive command in accordance with a game condition to the first holding output circuit. Consequently, the game machine restrains noise from being misdetected as the read command by the peripheral control means. As the result, since the reception of wrong control data by a peripheral control means is prevented, a normal peripheral control is unerringly performed by the peripheral control means.
