<p>PROBLEM TO BE SOLVED: To reduce the number of components while inhibiting light of a second light source from leaking to an optical path of a first light source and inhibiting light of the first light source from leaking to an optical path of the second light source.SOLUTION: A push button device 10 of a game machine 1 includes a light source substrate 105, a first light guide member 106, and a diffusion lens 107. The back side of the diffusion lens 107 faces the light source substrate 15. The first light guide member 106 is fitted in a through-hole 107a formed on the diffusion lens 107, is mounted on the light source substrate 105 such that one end side thereof covers a first light source 205, and the other end side protrudes from the backside of the diffusion lens 107 in a direction of heading towards the surface. Light of a second light source 305 of the light source substrate 105 enters the diffusion lens 107 from the back side and is diffused from the surface of the diffusion lens 107. Light of the first light source 205 of the light source substrate 105 enters the first light guide member 106 from one end side of the first light guide member 106 and exits from an exit plane in the other end side of the first light guide member 106.</p> |
