SOLUTION: If a person inserts a fraudulent operating member 18 such as a piano wire or a coin into the gap 11 from the front side of a game machine frame 1 when a control device 17 is actuated with the power supply and is feeding the operating power to a detector 12, a movable body 14, which is pressed/moved by the fraudulent operating member 18 against the elasticity of an elastic body 16, presses and moves a button 13. Then, the detector 12 is turned on and outputs a foreign matter intrusion signal to the control device 17. The control device 17 drives an alarm 19, and the alarm 19 notifies the intrusion of the fraudulent operating member 18 into the gap 11. COPYRIGHT: (C)2004,JPO&NCIPI
