PROBLEM TO BE SOLVED: To surely make an input part for inputting a detection signal of a detecting means for detecting a game medium give, when connector is pulled out, an output of a level definitely different from that when the detecting means is detecting the game medium. SOLUTION: The power voltage is connected to a connecting terminal 191a at one side through a resistor R1. Emitters of transistors Q1, Q2 are connected to the power source side of the resistor R1. The base of the transistor Q1 is connected to the connecting terminal 191a side of the resistor R1. A collector of the transistor Q1 is grounded through a resistor R2 and connected to the base of the transistor Q2. A connecting terminal 191b that transmits the detected signal of a start-up opening switch 14a of an adjacent switch is connected to the input side of an input port 580 through a resistor R5 for limiting the current. A resistor R4, with its one end grounded, is connected to the connecting terminal 191b side of the resistor R5. In addition, a collector of the transistor Q2 is connected to the connecting terminal 191b side of the resistor R5 through a resistor R6 for setting the voltage. COPYRIGHT: (C)2004,JPO
