Has been. The switch function unit 41 is disposed substantially at the center of the substrate 40 and faces the pressing projection 26 e of the first light diffusion member 26.

  As shown in FIG. 2, four first light sources 42 and two second light sources 43 are provided. The first light source 42 faces the lower side of the illumination facing portion 26a of the first light diffusing member 26, and the first light source 42 and the first light diffusing member 26 constitute a first light emitting portion. The second light source 43 faces the lower end surface of the second light diffusing member 28, and the second light source 43 and the second light diffusing member 28 constitute a second light emitting unit.

  The switch function unit 41 provided on the substrate 40 is a mechanical switch element that incorporates electrical contacts and reaction force means. Or it is a thin membrane switch etc. with small operation reaction force, and the reaction force means is provided separately from the switch function part 41. FIG.

  When the operation member 20 is urged in the Z1 direction by the reaction force means included in the switch function unit 41 or the reaction force means provided separately from the switch, and the pressing force F is not acting, the operation member 20 operation surfaces 24a protrude from the opening 11a of the case 11 to the front side (upper side). When the pressing force F shown in FIG. 3 is applied to the operating member 20, the operating member 20 slides in the direction Z2 within the case 11, the switch function unit 41 is pressed by the pressing protrusion 26e, and the switch function unit 41 operates. Be made.

  When the operation member 20 moves in the Z1-Z2 direction, the first light diffusion member 26 and the second light diffusion member 28 move together with the operation member 20.

  In the first light emitting unit, the first light is provided from the first light source 42 to the first light diffusing member 26. The first light source 42 is an LED, and the first light generated in white is emitted. Therefore, the first light diffusion member 26 emits white light. In the second light emitting unit, second light is emitted from the second light source 43 to the second light diffusing member 28. The second light source 43 is an LED, and the second light emitted from the LED is a chromatic color, such as red, pink, orange, blue, or green.

  In addition, the 1st light source 42 and the 2nd light source 43 are LED or a lamp | ramp, 1st light and 2nd light are natural light or white light, the 1st light-diffusion member 26 is colored white, 2nd The light diffusing member 28 may be colored chromatic. Even in this configuration, white illumination light can be generated by the first light emitting unit, and chromatic illumination light can be generated by the second light emitting unit.

  Note that chromatic illumination light other than white may be emitted from the first light diffusion member 26 constituting the first light emitting unit.

  FIG. 5 shows an optical path that passes through the inside of the light guide 22. In FIG. 5, for ease of explanation, the first light emitting unit composed of the first light source 42 and the first light diffusing member 42 and the second light emitting unit composed of the second light source 43 and the second light diffusing member 28 are shown. Shown in block.

  When the first light source 22 is turned on, the first light diffusing member 26 that constitutes the first light emitting unit shines white, and when the second light source 23 is lit, the second light diffusing member 28 that constitutes the second light emitting unit is chromatic. Shines on.

  In FIG. 5, white light from the first light emitting unit is indicated by an optical path (A), and chromatic light from the second light emitting unit is indicated by an optical path (B). The refractive index inside the light guide 22 is larger than the refractive index of air outside the light guide 22. The light guide 22 and the operation knob 24 have the same refractive index.

  As shown in FIG. 5, the white light from the first light emitting unit enters the light guide 22 from the light incident surface Sb of the rear facing portion 22 b of the light guide 22, and a part of the light is guided to the light guide. The inside of 22 proceeds in the Z1 direction, but part of the other light is totally reflected inward by the inclined surface 22c of the light guide 22 as shown by the optical path (A). The amount of light totally reflected by the inclined surface 22c of the light guide 22 can be easily designed by selecting the inclination angle θ of the inclined surface 22c.

  The chromatic light from the second light emitting unit enters the light guide 22 from the inclined surface 22c of the light guide 22 and propagates through the light guide 22 as indicated by the optical path (B). Since the second light diffusing member 28 faces the inclined surface 22c from the lateral direction (X1-X2 direction) which is a direction orthogonal to the center line O, the larger the inclination angle θ of the inclined surface 22c, the second light emission. Chromatic light emitted from the portion easily enters the light guide 22.

  Since the light shielding part 21 is provided between the light guide 22 and the operation knob 24 and light is shielded by the light shielding part 21, the light propagating inside the light guide 22 is notated by musical notes formed in the light shielding part 21. Are transmitted forward through the light transmission part Sa formed around the shading part 21 and the area of the figure.

  When the operation surface 24a of the operation knob 24 is viewed from the front (Z1 direction), the musical note graphic area formed on the light shielding portion 21 is illuminated. Since the musical note area is formed in white in the light shielding part 21, this area appears to be mainly white, and depending on the viewing angle, it appears to be illuminated with chromatic light from the second light emitting part.

  When viewed from the front, the light transmitting portion Sa surrounding the light shielding portion 21 is brightly illuminated. At this time, the color of the light that illuminates the light transmitting portion Sa looks different depending on the viewing direction and angle. As shown in FIG. 5, since the inclined surface 22c faces the light transmitting portion Sa, the inclined surface 22c is seen from the front through the light transmitting portion Sa, and is totally reflected by the inclined surface 22c. The reflected light looks like reflected light from the mirror surface, and the light transmitted through the inclined surface 22c can also be seen. For this reason, the light transmitting portion Sa is in an illuminated state with a three-dimensional feeling and a depth feeling, and the light shielding portion 21 has an appearance that is floating in space or floating in water, so that the illuminated state has a high-class feeling. Arise. The illumination state also varies depending on the viewing direction and angle.

  For example, as shown in FIG. 5, when the operation member 20 is viewed from obliquely upward to the right in the drawing, the light path (B) of the light transmission part Sa around the light shielding part 21 in the right part close to the eyes of the operator is shown. White light in the optical path (A) appears stronger than chromatic light. In the left part far from the eyes of the operator, the chromatic color light in the optical path (B) looks stronger than the white light in the optical path (A). Therefore, although the white light emitted from the first light emitting part and the chromatic light emitted from the second light emitting part appear to be mixed in the light transmitting part Sa, white illumination light is emitted in an area close to the eyes of the operator. The chromatic illumination light appears to be emphasized in a region far from the operator's eyes.

  On the contrary, when viewed from the upper left side opposite to that shown in FIG. 5, the light transmitting portion Sa on the outer periphery of the light shielding portion 21 appears to emphasize the white illumination light in the region on the left side of the drawing, and the right side. The chromatic color light is emphasized in the area of.

  The illumination state of the light transmitting portion Sa as described above is schematically shown in FIG. 6, and an actual photograph of the illumination state is as shown in FIG.

  As shown in FIG. 7, in the light transmission portion Sa, white illumination light and chromatic illumination light appear to have a sense of depth, and a high-quality feeling can be given to the illumination state of the operation member 20.

  In addition, since the first light diffusing member 26 and the second light diffusing member 28 move together with the operation member 20, the illumination state of the light transmitting portion Sa can be obtained even when the operation member 20 is not pressed or during the pressing operation. Are always the same, and always in a high-quality illumination state.

  However, in the present invention, the first light diffusion member 26 and the second light diffusion member 28 may be fixed. In this case, when the operation member 20 moves, the relative position between the inclined surface 22c and the second light diffusing member 28 changes, so that the operation member 20 is not operated and is pressed. The illumination state of the light transmission part Sa changes.

  As shown in FIG. 3, since the light absorbing portion 27 is provided in the flat plate portion 26 c of the first light diffusing member 26, white light emitted from the first light emitting portion is applied to the light guide 22. Since chromatic light incident only from the rear facing portion 22b and emitted from the second light emitting portion is incident only from the inclined surface 22c, as shown in FIG. 5, the optical paths (A) of light of different colors and The optical path (B) can be divided, and the contrast of the illumination state of the light transmission portion Sa can be enhanced.

  However, in the present invention, the first light diffusing member 26 may be exposed in the portion of the light absorbing portion 27 without providing the light absorbing portion 27, or the second light diffusing member 28 may be provided in the portion of the light absorbing portion 27. You may extend and arrange.
