PROBLEM TO BE SOLVED: To provide a game machine configured to identify opening of a door body when a game machine is off.SOLUTION: A frame open detection circuit 260 outputs an output signal SG4 in response to power-on of a Pachinko machine 10 when an inner frame 12 or a front frame 14 are opened during power-off of the Pachinko machine 10, power is supplied to a switch SW1 or a switch SW2, and a charged capacitor CD1 is discharged. The frame open detection circuit 260 outputs no output signal SG4 when the Pachinko machine 10 is turned on if the inner frame 12 or the front frame 14 is not opened (closed) during power-off of the Pachinko machine 10, and the capacitor CD1 is kept charged. Consequently, the Pachinko machine 10 in which inner frame 12 or front frame 14 is opened during power-off of the Pachinko machine 10 can be identified. |
