上記手段では、導光部材内において凹部から操作部材に直接至る光経路上に遮 光壁が介在し、凹部に挿入されている光源の光が操作部材へ直接及ばないように なっている。よって光源の光は、導光部材内において前記遮光壁を迂回して操作 部材の周囲に及ぶことになり、操作部材の周囲にある導光部材が均一に発光し、 偏りのない照光ができるようになる。また遮光壁は操作パネルの内側に一体に突 出し、これが導光部材の溝に嵌合されているため、この嵌合により導光部材の位 置決めもできるようになる。 In the above means, the optical path from the recess directly to the operating member is blocked in the light guiding member. A light wall is interposed to prevent the light from the light source inserted into the recess from directly reaching the operating member. It has become. Therefore, the light from the light source is operated by bypassing the light shielding wall within the light guide member. The light guide member around the operating member emits light uniformly, This allows for unbiased illumination. In addition, the light-shielding wall is integrated into the inside of the operation panel. Since this is fitted into the groove of the light guide member, the position of the light guide member is changed by this fitting. You will also be able to decide on the location.

【００１４】 上記の操作部照光装置の照光動作を説明する。 車載用音響装置では、夜間において自動車の予備ライトの点灯スイッチを入れ ると、ランプ３２が点灯する。このランプ３２の光は凹部２２ａと２２ｂから導 光部材２０内に導かれる。ただし凹部２２ａの図示上下方向は遮光壁１５ａと１ ５ｂにより囲まれており、また凹部２２ｂの図示上方は遮光壁１５ｃにより囲ま れている。そのため、凹部２２ａと２２ｂ内から各穴２１ａないし２１ｄへ至る 直接の光経路は遮断され、光は遮光壁１５ａないし１５ｃにより囲われていない 乱反射プリズム２３ａないし２３ｄの方向へ導かれる。各乱反射プリズム２３ａ ないし２３ｄの方向へ直接進行する光は、裏面の傾斜面２６ａないし２６ｄのギ ザ部により乱反射され、さらにこの傾斜面により導光材料１４ａないし１４ｄの 方向へ照射される。これにより図２に示す表示部１３ａないし１３ｄは非常に明 るい発光状態となり、外部から目視したときに確認しやすくなる。[0014] The illumination operation of the above operation unit illumination device will be explained. In-vehicle audio equipment turns on the vehicle's backup lights at night. Then, the lamp 32 lights up. The light of this lamp 32 is guided from the recesses 22a and 22b. guided into the optical member 20. However, the vertical direction of the recess 22a in the drawing is between the light shielding walls 15a and 1. 5b, and the upper part of the recess 22b in the drawing is surrounded by a light shielding wall 15c. It is. Therefore, each hole 21a to 21d is reached from inside the recesses 22a and 22b. The direct light path is blocked and the light is not enclosed by the light blocking walls 15a to 15c. The light is guided in the direction of the diffuse reflection prisms 23a to 23d. Each diffuse reflection prism 23a The light traveling directly in the directions 23d to 23d is directed to the gears on the sloped surfaces 26a to 26d on the back side. It is diffusely reflected by the light guide material 14a to 14d due to the inclined surface. irradiated in the direction. This makes the display sections 13a to 13d shown in FIG. 2 very bright. It emits bright light, making it easier to see from the outside.
【００１５】 さらに凹部２２ａと２２ｂから乱反射プリズム２３ａないし２３ｄの方向へ送 られた光は、遮光壁１５ａ，１５ｂ，１５ｃを迂回して、貫通穴２１ａないし２ １ｄの周囲に至る。そして図２に示すように操作パネル１１の穴１２ａないし１ ２ｄの内側に露出しているギザ状の縁部２７ａないし２７ｄが発光し、操作部材 ３１の周囲が明るく照らされる。前記遮光壁１５ａないし１５ｃにより、凹部２ ２ａと２２ｂ内のランプ３２の光は貫通穴２１ａないし２１ｄに直接至ることな く迂回して周囲に至る。よって図３に示すように、操作部材の周囲に偏った照光 がなされることはなく、均一な照光が得られるようになる。[0015] Furthermore, the light is sent from the concave portions 22a and 22b toward the diffuse reflection prisms 23a to 23d. The emitted light bypasses the light shielding walls 15a, 15b, and 15c and enters the through holes 21a to 2. It reaches around 1d. As shown in FIG. 2, holes 12a to 1 of the operation panel 11 The jagged edges 27a to 27d exposed on the inside of 2d emit light, and the operation member The area around 31 is brightly illuminated. The light shielding walls 15a to 15c allow the recess 2 The light from the lamps 32 in 2a and 22b does not directly reach the through holes 21a to 21d. Take a detour to reach the surrounding area. Therefore, as shown in Figure 3, the illumination is biased around the operating member. Uniform illumination can be obtained.
【００１６】 なお図の実施例では車載用音響機器に設けられる操作部照光装置について説明 したが、他の車載用の操作部あるいは家庭用の機器などにおいても本考案の照光 装置を採用することは可能である。[0016] The example shown in the figure explains the operation unit illumination device installed in in-vehicle audio equipment. However, the illumination of this invention can also be used in other in-vehicle operation units or household equipment. It is possible to employ the device.
【００１７】[0017]
以上のように、本考案によれば、凹部に挿入された光源から操作部材の方向へ 直接光が伝達されず、迂回した光により操作部材の周囲を発光させているため、 光の偏りがなく、均一な照光が可能になる。 As described above, according to the present invention, from the light source inserted in the recess toward the operating member, Because the light is not transmitted directly and the area around the operating member is illuminated by the detoured light, There is no polarization of the light and uniform illumination is possible.
