  As shown in FIG. 4 (exploded perspective view), the speaker 43 of the sound emitting unit 41 includes a cone-shaped diaphragm 44. When an electrical signal flows through a voice coil provided in the speaker 43, the electrical signal Is converted into sound waves. In front of the speaker 43, a foreign object insertion detection device 50 that detects whether or not a foreign object such as a wire has been inserted toward the diaphragm 44 from the sound escape hole 11j provided in the lower portion of the panel section 11 shown in FIG. Is arranged.

  This foreign matter insertion detection device 50 will be further described with reference to FIG. 5 (front view). A support body 51 disposed in front of the diaphragm 44 and formed in a rectangular tube shape, and a rotating body 51 inside the support body 51. A rotating plate 53 held at a position (hereinafter, referred to as a normal position Pn) that is disposed so as to be movable and is substantially vertical so as to cover the front surface of the speaker 43, and is attached to both ends of the rotating plate 53. And a rotation detector 55 that detects whether the rotation plate 53 has rotated over a predetermined angle from the normal position Pn.

  The support 51 is installed with the opening 51 a on one end side facing the diaphragm 44 of the speaker 43 and the end on one end side of the support 51 being placed close to the front end of the speaker 43. The opening 51 a of the support 51 has a size that covers the front surface of the diaphragm 44 of the speaker 43. The support 51 may be formed in a cylindrical shape as long as the opening 51 a includes the front surface of the diaphragm 44.

  The rotating plate 53 is formed in a disc shape, and the pair of rotating shafts 53a are arranged on a straight line passing through the center of the rotating plate 53 and extend radially outward. These rotation shafts 53a are rotatably supported by a pair of rotation support portions 59 provided in the support body 51 with a predetermined interval. The rotation plate 53 supported by these rotation support portions 59 is formed such that the lower portion 53b is heavier than the upper portion 53c than the pair of rotation shafts 53a. For this reason, when the rotating plate 53 is in a natural state in which no bias is applied, the heavy lower portion 53b is positioned below the pair of rotating shafts 53a, and the rotating plate 53 is substantially vertical. It is held at the normal position Pn extending in the direction.

  The rotating plate 53 is provided with a large number of mesh-shaped holes 53d through which sound generated from the speaker 43 is passed and at which elongated foreign matters such as wires are caught. The size of the hole 53d is substantially the same as or smaller than the diameter of the wire having a diameter capable of breaking through the diaphragm 44 of the speaker 43. For this reason, when a wire capable of breaking through the diaphragm 44 from the front of the rotating plate 53 toward the speaker 43 is inserted into the slot machine 1, the tip of the wire is caught in the hole 53 d of the rotating plate 53. When the wire is further inserted to the speaker side, the rotating plate 53 is urged to rotate.

  A rotation detector 55 is attached to the rotation plate 53 configured as described above. The rotation detector 55 is attached to the rotation support part 59 and detects a rotation angle (for example, a potentiometer) 56 from the normal position Pn of the rotation plate 53, and a detection signal of the rotation sensor 56. Based on the above, it is detected whether or not the rotating plate 53 has rotated beyond a predetermined angle from the normal position Pn, and if it is detected that the rotating plate 53 has rotated beyond the predetermined angle from the normal position Pn, the speaker 43 is detected. And a detector 57 for sending a detection signal to the main control board 24 indicating that a foreign object such as a wire has been inserted.

  The detection unit 57 is configured such that the adjustment of the predetermined angle can be changed to an arbitrary angle. By setting the predetermined angle, it is possible to prevent an erroneous detection that the rotating plate 53 is rotated by vibration or the like and a foreign object such as a wire is inserted.

  In this way, 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 rotating plate 53 and further wire is inserted. When the rotation plate 53 rotates, the rotation sensor 56 detects the rotation angle of the rotation plate 53. When the rotation angle of the rotation plate 53 exceeds a predetermined angle from the normal position Pn, the detection unit 57 outputs a detection signal indicating that a foreign object such as a wire is inserted toward the speaker 43 as described above. Send to. 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 44 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, the host computer in the hall is informed that a foreign object has been inserted in front of the speaker 43 when the rotating plate 53 rotates. It is possible to prevent fraudulent acts against the above and provide a fair game.

  In the embodiment described above, the slot machine 1 is taken as an example, but a game machine used in a pachinko or game center may be targeted.
