PPROBLEM TO BE SOLVED: To minimize increase of the number of terminals for preventing scale from becoming large when increasing types of detection signals in a security system of a game machine. PSOLUTION: An opening and closing switch 111 opens or closes based on detection or non-detection of magnetism by a magnetic sensor 2. A Zener diode ZD111 is serially connected to the opening and closing switch and generates voltage of a value very similar to a voltage value of residual voltage generated when an electronic switch 1 is closed. A constant current generating part 113 generates current of a value very similar to a leakage current value which flows in when the electronic switch 1 is opened. Thus, characteristics of output signals from the electronic switch 1 and the magnetic sensor 2 are the same so that an I/F device 3 is connected without awareness of the electronic switch 1 and the magnetic sensor 2 and that interface processing is performed by separating them. This invention is applied to a security device of the game machine. PCOPYRIGHT: (C)2010,JPO&INPIT
