A lighting member 7, which is a feature of the present invention, is embedded in a cavity formed between the lower outer plate 6a of the lower rack main body 6 and the lower swash plate 6h. This lighting member 7 is shown in FIG. 5 (front perspective view).
It has the shape shown in FIG. 6 (rear perspective view), FIG. 7 (front view), and FIG. 8 (rear view). This lighting member 7 is integrally molded from a transparent acrylic material, and has two light projection surfaces 7b formed on its upper surface with a central groove 7a in between. This light projection surface 7b is a curved surface that descends in the front direction,
The light projection surface 7b is exposed upward through two light projection windows 8 opened in the lower swash plate 6h of the lower rack main body 6. Further, the surface opposite to the light projection surface 7b, ie, the lower surface of the illumination member 7, is a diffused reflection surface 7c on which countless small irregularities are formed. As shown in FIG. 8 (rear view), FIG. 9A (A-A sectional view), and FIG. 9B (B-B sectional view), the rear edge 7d of the diffused reflection surface 7c is located at the center of the illumination member 7. In other words, the groove 7a is formed so as to be raised to the highest point at the position of the groove 7a.

is drilled. Further, a pair of projections 7h are integrally formed at a portion of the back surface of the lighting member 7 that is slightly closer to the center than the mounting portion 7e. on the other hand,
As shown in FIGS. 5 and 6, a miniature light bulb 9 serving as a light source is attached to a bracket 10.

This bracket 10 is constructed so that the light emitted from the miniaturized light bulb 9 can be shielded by two surfaces 10a and 10b to prevent it from leaking upward and inward. Further, a mounting portion 10c is protruded from the front end of the upper surface 10b of the bracket 10, and a mounting hole 10d is bored therein, while an engaging portion 10e is protruded from the front end of the inner side surface 10a of the bracket 10. and an engagement hole 10f is bored therein. This bracket 10 is connected to the lighting member 7, respectively.
A pair of fitting holes 10f of the bracket 10 are fitted into the protrusions 7h on the back side of the lighting member 7 to position them (FIG. 6). Furthermore, the mounting hole 10d of the bracket 10 and the lighting member 7
The mounting screw 11 is inserted into the mounting hole 7g, and the bracket 10 and the lighting member 7 are integrated into the female threaded hole 12 (the fourth (see Figure 6).

The lighting member 7 constructed as described above is attached to the lower rack body 6, and the cassette tape player 1, equalizer 2, and amplifier 3 are operated by the lower rack body 6 and the upper rack body 5 as shown in FIG. It is assembled so as to cover the surrounding area of the front.

When the two miniature bulbs 9 are turned on while the vehicle is running at night, the light emitted from the miniature bulbs 9 passes through the interior of the lighting member 7 and is first formed at both longitudinal ends of the lighting member 7. The light is reflected by the reflective surface 7e and directed toward the center of the interior of the illumination member 7. Then, this light is diffusely reflected by the unevenness of the diffused reflection surface 7c, and is reflected by the light projection surface 7 above the diffused reflection surface 7c.
It is irradiated to the outside from b. This irradiation light is emitted upward from the light projection window 8 of the lower rack main body 6, so that the operation front surface 1a of the cassette tape player 1,
The operation front surface 2a of the equalizer 2 is projected with appropriate brightness. Therefore, even when driving at night, the operation of inserting the cassette pack into the cassette pack insertion slot 1b, the various dials 1c, the operation buttons 1d,
2c, the switch 2b can be operated without mistakes.

Further, as shown in FIGS. 8, 9A, and 9B, the rear edge 7 of the diffused reflection surface 7c of the illumination member 7
Since d is raised at the center, the light reflected by the reflective surfaces 7e at both ends uniformly hits the entire area of the diffused reflective surfaces 7c. As a result, it is possible to irradiate bright light even in the central portion of the illumination member 7, and it becomes possible to uniformly project light onto the operation front surfaces 1a and 2a.

In the illustrated embodiment, the illumination member 7 is provided in the lower swash plate 6h of the lower rack main body 6, but the illumination member 7 is provided in the upper swash plate 5h of the upper rack main body 5, the both side swash plates 5i,
It may be buried within 6i.

As described above, according to the present invention, since the lighting member is disposed at the front end of the rack body, the front of the operation of multiple in-vehicle audio equipment can be illuminated even when driving at night, so the front of the operation is moderately bright. This makes it possible to prevent erroneous operations. In addition, since this lighting member is molded from a transparent material and a light source is connected to this lighting member, the front of the operation is indirectly illuminated, and the light from the light source does not directly reach the driver, so it does not interfere with driving. There is no effect.
