To eliminate the vagueness in the voice command input timing.

A voice recognizer (voice recognition engine 115) is carried by the game machine to indicate the operation for starting or stopping the rotation of the spin drum reels by voice replacing hands, thereby controlling the rotation of the spin drum reels. When the voice command is uttered while the spin drum reels are made unable to rotate (waiting position), the central control part 111 temporarily stores it to eliminate the need for inputting the voice again after the release of the waiting position. Moreover, the central control part 111 is mounted together with the voice recognizer on a sub control board installed independently of the main control board.
