Summary:PROBLEM TO BE SOLVED: To give information for illegal action at the time when a power supply for game facilities is cut off. SOLUTION: A capacitor C1 is charged even when the power supply for a game machine installation island 20 is cut off. When a front frame 27 is opened by anyone, an opening detection switch SW1 is closed (turned on) and the charge of the capacitor C1 is discharged. Then, even if the front frame 27 is closed and the opening detection switch SW1 is opened, the capacitor C1 is not charged because the power supply remains cut off. When the power supply is turned on the next day, the capacitor C1 is charged, but it takes 1-2 seconds or so for completing the charge. In the meantime, the input side of a reversing circuit Inv is at a potential parted by a resistance R2 and a resistance R3, namely at a low level, and the output side is at a high level. Thus, a transistor TR is turned on and a light emitting diode LED1 is lit on. The light-on proves that illegal action is taken for mounting incorrect parts including a wrong ROM and a hanging board by anyone stealing in after closed, resulting in proper measures to be taken.
