The main body 54a of the moving member 54 is provided with a large number of mesh-shaped holes 54c through which sound generated from the speaker 43 is passed and at which a long and narrow foreign object such as a wire is caught. The size of the hole 54c is substantially the same as or smaller than the diameter of the wire having a diameter capable of breaking through the diaphragm 45 of the speaker 43. For this reason, when a wire capable of breaking through the diaphragm 45 from the front of the moving member 54 toward the speaker 43 is inserted into the slot machine 1, the tip of the wire is caught in the hole 54c of the moving member 54, and the wire Is further inserted to the speaker side, the moving member 54 is urged to move relative to the support member 51.

  A movement detector 57 is attached to the support member 51 that movably supports the moving member 54 configured as described above. The movement detector 57 is attached to the support member 51 and detects the amount of movement that the moving member 54 has moved from a predetermined position (for example, an intermediate position in the front-rear direction of the moving hole 51b), and this movement amount exceeds a predetermined distance. When the movement is detected, it has a function of sending a detection signal indicating that a foreign object such as a wire has been inserted toward the speaker 43 to the main control board 24 described above.

  The movement detector 57 is configured so that the adjustment of the predetermined distance can be arbitrarily changed. By setting the predetermined distance, the moving member 54 is moved by vibration or the like, and a foreign object such as a wire is inserted. It is possible to prevent a situation in which an erroneous detection is made. Further, the moving member 54 may be provided in the cylindrical body 51c of the support member 51 via a spring member (not shown) so that the moving member 54 can automatically return to a predetermined position.

  As described above, by providing the foreign matter insertion detection device 50 in front of the speaker 43, when a long and narrow foreign matter such as a wire is inserted from the sound escape hole 11j, the wire hits the moving member 54 and enters the hole 54c of the moving member 54. When the moving member 54 is moved by being caught and inserted by a further wire, the movement detector 57 detects the moving distance of the moving member 54 from a predetermined position. When the moving distance of the moving member 54 exceeds a predetermined distance, the movement detector 57 sends a detection signal indicating that a foreign object such as a wire has been inserted toward the speaker 43 to the main control board 24 described above. When the main control board 24 receives this detection signal, it notifies the hall host computer that a foreign object has been inserted in front of the speaker 43.

  For this reason, the diaphragm 45 of the speaker 43 is pierced by the insertion of a foreign object such as a wire, so that the speaker 43 does not emit sound, and then the main control board 24, the sub control board 32, the power supply board 27, etc. Even if an illegal act is attempted, when the moving member 54 moves, the host computer in the hall is informed that a foreign object has been inserted in front of the speaker 43. Cheating can be prevented and fair games can be provided.
