PROBLEM TO BE SOLVED: To provide a game machine capable of grasping the opening, if any, of a door body in the case where the door body is opened while the electric power source of the game machine is turned off.SOLUTION: If an inner frame or a front frame is opened, while the power source of a pachinko machine is off, and if a switch SW1 or a switch SW2 is turned on, a frame opening detecting circuit 260 begins to output a stop signal, a reset signal and a drive voltage to an MPU. After about 4.4 seconds elapsed after the inner frame or the front frame was opened, the frame opening detecting circuit stops a power failure signal and causes a capacitor CD4 to start the discharge. After this, the frame opening detecting circuit stops the reset signal and the drive voltage finally. Even if the inner frame or the front frame is released, when the power source of a pachinko machine is off, so that the MPU is temporarily raised, and the raised MPU is normally ended. |
