PROBLEM TO BE SOLVED: To prevent a malfunction of a device even when an IC for transmitting intrinsic identification information provided for preventing fraudulence through a radio wave is provided near the device affecting a game result. SOLUTION: A main controller 80 is provided with: an IC 100 for transmitting the intrinsic identification information preliminarily memorized as receiving a prescribed call wave; and an IC power source control circuit 101 for controlling power supply to the IC. The IC power source control circuit 101 is made not to supply a backup power source supplied from a power source substrate (power source device) 85 to the IC 100 during a normal game, and is made to supply the backup power source to the IC 100 when a signal indicating that the power source to a pachinko machine 50 is interrupted is input from a power interruption detection circuit 110, so that the malfunction of the main controller 80 by the radio wave output by the IC 100 can be prevented.
