- the operation button 1 is formed of a columnar, in the illustrated example, a columnar transparent synthetic resin material, and characters, symbols, and the like are displayed on a front portion thereof.
- a rocking plate 2 made of synthetic resin material that can transmit light is adhered.
- One side of the oscillating plate 2 is an elastic piece and is swingably connected to the holder 4 via a pair of thin hinges 3. The moving plate 2 swings while slightly tilting about the thin hinge 3 as a fulcrum.
- a plate-shaped light diffusion prism member 5 is adhered to the back surface of the oscillating plate 2.
- the light diffusing prism member 5 reflects and diffuses light emitted from the light emitting unit 11 described later and guides the light to the operation button 1. Therefore, the planar shape of the light diffusing prism member 5 is as shown in FIG. It has a composite shape in which both ends of a semicircle X whose radius of curvature is almost equal to the arc representing the cross-sectional shape of X are connected to both ends of the base of the isosceles triangle Y. It has become.
- the light diffusion prism member 5 has a first reflection surface 6 for guiding incident light from a light emitting unit 11 described later into the light diffusion prism member 5, and a light reflected by the first reflection surface 6 on the operation button 1. And a second reflecting surface 7 for guiding.
- the first reflecting surface 6 is formed of an inclined surface formed by cutting off a vertex of an isosceles triangle Y of the light diffusing prism member 5 and inclined toward the midpoint M of the semicircular arc.
- the second inclined surface 7 is formed by gradually decreasing the thickness from the apex of the isosceles triangle Y of the light diffusing prism member 5 toward the semicircular arc X side. It is composed of an inclined surface inclined toward.
- a light diffusion prism member 5 is a rocking plate.
- the first reflecting surface 6 is disposed so as to be located on one side of the swinging plate 2 with respect to the thin hinge 3 on one side of the swinging plate 2.
