Abstract

An illumination mechanism for an escutcheon portion of a car sound device such as a car radio, car stereo, etc. The illumination mechanism comprises a light-transmissible plate provided at the front of the escutcheon portion and an illuminating lamp or lamps provided behind the light-transmissible plate. A cassette or cartridge receiving opening is formed in the light-transmissible plate and operating members for the sound device are provided on the plate.

Claims

1. In an automotive stereo device having an escutcheon portion at the front thereof, said escutcheon portion having wall means defining an opening for receiving a tape cassette or cartridge and having at least one operating member for controlling operation of the stereo device, an illumination mechanism comprising a light-transmissive plate made of a material having a high light transmissivity, said plate being mounted at the forward end of said escutcheon portion and having a cutout portion provided therein, at least one illuminating lamp provided behind said plate for illuminating said plate, said operating member being supported in front of said plate and said wall means being located in said cutout portion of said plate, said wall means being made of a material having a lower light transmissivity than that of said plate so that when said lamp is lit, said wall means will be of lower brightness than said plate.

2. An automotive stereo device as claimed in claim 1 wherein said escutcheon portion has a rectangular front wall, said plate forms a portion of said front wall and extends substantially the width of said front wall, said plate having an end portion extending partway across the width of said front wall and extending substantially the height of said front wall and the remainder of said plate being of reduced height and extending along the lower portion of said front wall, the zone above said remainder of said plate defining said cutout portion.

3. An automotive stereo device as claimed in claim 1, wherein said operating member is made of a material having a lower light transmissivity than that of said plate.

4. An automotive stereo device as claimed in claim 1, wherein said plate is made of a colored light-transmissive material.

5. An automotive stereo device as claimed in claim 1, which further comprises a back plate provided behind said light-transmissive plate and a lamp holder provided at an end of said back plate for holding said illuminating lamp.

6. An automotive stereo device as claimed in claim 1, including an openable dust cover for closing said opening, said wall means comprising a trim member having a light introducing opening in a side face thereof for introducing light from said illuminating lamp onto the front of said dust cover to illuminate said cover.

7. An automotive stereo device as claimed in claim 6, which further comprises a color cap covering said illuminating lamp.
