  In the conventional calling lamp as described above, a calling button for turning on the light source is provided separately from the calling lamp, so that not only the number of parts increases, but also a space for arranging the calling button. There was a problem that would be necessary.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to reduce the number of parts and eliminate the need for a space for arranging a light source lighting operation member.

  In order to achieve this object, the present invention provides a light source, a switch for turning on the light source, a light diffusing member that covers the light source and the switch, and is supported so as to be movable forward and backward, and the light diffusing member. A lens that moves the light diffusing member forward toward the switch when covered and pressed, and causes the light diffusing member to advance the light diffusing member toward the switch via the lens. An operating part for operating the switch is provided.

  The present invention includes, in the above invention, a printed circuit board on which the light source and the switch are mounted, and a base on which the printed circuit board is mounted and supports the light diffusing member, and the light diffusing member is disposed between the base and the base. And an elastic piece that urges the light diffusing member that has been advanced by the lens in a direction in which the light diffusing member is retracted.

  According to the present invention, since the lens also serves as an operation member for operating the switch, not only the number of parts is reduced, but also a dedicated space for arranging a button for operating the switch becomes unnecessary. Further, since the light diffusing member is indirectly pressed through the lens, the deformation of the light diffusing member can be prevented. In addition, the operability is improved because the outer shape of the lens is larger than that of a conventional button operation.

  As described above, in the calling lamp 1 attached to the installation surface around the gaming machine, when the player calls an attendant, the lens 9 is moved by pressing the top portion 9b of the lens 9 in the arrow B direction with a finger or the like. Move in the direction of arrow B. In conjunction with the movement of the lens 9 in the arrow B direction, the light diffusing plate 8 in which the lower end of the opening end portion 9a of the lens 9 is in contact with the flange 21 resists the urging force of the elastic piece 22 in the arrow B direction. Move to.

  Since the light diffusing member 8 moves in the direction of arrow B and the collar 21 of the light diffusing member 8 is locked to the locking piece 14, the limit switch 4 is operated by the operating projection 20a, so that the LEDs 3 and 3 are lit. To do. By releasing the pressing operation of the top portion 9b of the lens 9 in the arrow B direction, the light diffusing member 8 is moved in the arrow A direction by the biasing force of the elastic piece 22, and in conjunction with this, the lens 9 is also moved in the arrow A direction. Moving.

  As described above, since the lens 9 also serves as a member for operating the switch 5, not only the number of parts is reduced, but also a dedicated space for arranging a button for operating the switch 5 becomes unnecessary. In addition, since the light diffusing member 8 is indirectly pressed through the lens 9, deformation of the light diffusing member 8 can be prevented. In addition, the operability is improved because the outer shape of the lens 9 as the operation unit is larger than that of the conventional button operation. Further, by providing the elastic piece 22 integrally with the light diffusing member 8, not only forgetting to assemble the urging member is eliminated, but also the number of assembling steps can be reduced.

  In the present embodiment, the light diffusing member 8 is returned only by the urging force of the elastic piece 22, but a compression coil spring is interposed between the base 6 and the light diffusing member 8, and the elastic piece 22 and a compression coil spring may be used in combination.
