PROBLEM TO BE SOLVED: To provide a game machine capable of grasping the opening of a door body in the case where the opening is performed while the electric power source of the game machine is off.SOLUTION: If an inner frame of a front frame is opened, while the power source of a pachinko machine is off, to turn on a switch SW1 or a switch SW2 so that a capacitor CD1 in the charged state becomes a discharge state, a frame opening detection circuit 260 outputs an output signal when the power source of the pachinko machine is turned on. On the other hand, if the inner frame or a front frame is not opened (or closed) while the power source of the pachinko machine is off so that the capacitor remains in the charge state, the output signal is not outputted when the power source of the pachinko machine is turned on. Hence, there is grasped the pachinko machine which has the inner frame or the front frame opened when the power source of the pachinko machine is turned off. |
