PROBLEM TO BE SOLVED: To prevent a storage area from becoming excessive by using circulation type counting means for counting detection times of opening of a glass door or the like and detection times of electric disconnection between a board and a frame, and further prevent such a trouble that a counted value of the circulation type counting means makes a circuit so as not to detect the opening and the disconnection.SOLUTION: In a normal state where a power supply of a P game machine is ON, the P game machine circulatingly (loop) counts detection times between 0-62, however, in a monitoring state where the power supply is OFF, causes a storage value area to store the detection times n when the power supply is OFF, then, addingly updates a current value table for counting a current value of the detection times to n, n+1, n+2, ... for each detection, and, in a next power up, outputs a difference value between the storage value of the storage value area and a counted value of the current value table. Further, when a count value of the current value table makes a circuit, the game machine puts a circuit flag on and, when the value is not addingly updated any more, outputs the circuit flag at the next power up. |
