PROBLEM TO BE SOLVED: To provide a game machine capable of informing a specific device of the opening of a door body even in the case where the power source of the game machine is off.SOLUTION: A frame opening detection circuit 260 is equipped with a capacitor CD1, so that even in the case where a power supply to a Pachinko machine 10 is blocked to supply no DC voltage of 12 volts from a DC power source DC1, the frame opening detection circuit 260 can output a pulse signal having a pulse width of about 10 ms according to an inner frame 12 or a front frame 14, to a hall computer 262 continuously operating for 24 hours. Even if the power supply to the Pachinko machine 10 is blocked, therefore, the opening of the inner frame 12 or the front frame 14 can be detected. Moreover, it is possible to specify the Pachinko machine 10 having the inner frame 12 or the front frame 14 opened, and the open time of the inner frame 12 or the open time of the front frame 14 of the Pachinko machine 10 specified. |
