The game control microcomputer sets data representing the number of prize balls to be paid out by making a predetermined bit of the prize ball request signal different, and transmits the set prize ball request signal to the payout control microcomputer. The payout control microcomputer transmits a reception ACK signal representing the preparation of paying out prize balls and a reception ACK signal for specifying a predetermined error, when a predetermined error is generated and the payout of prize balls is made impossible. |
