PROBLEM TO BE SOLVED: To ensure the accuracy of game results by inhibiting a command from a main control device to a put-out control device when a power supply shut-off occurs. SOLUTION: When a power supply device 2 outputs a power supply shut-off signal 11 due to power failure 12 to the main control device 21 through wiring 14, a micro-computer of the main control device 21 outputs a power supply shut-off signal 23 to the put-out control device 31 through wiring 24 with detection of the power supply shut-off signal 11 at the port input by programmed polling, and performs saving processing for a backup to the power supply shut-off signal 11. On the other hand, a micro-computer of the put-out control device 31 performs saving processing for a backup to the power supply shut-off signal 23 with detection of the power supply shut-off signal 23.
