Abstract
Light shielding portions made from light shielding resin material, and light conducting portions made from transparent or translucent resin material are formed integrally with each other by two-layer molding to thereby reduce the number of manufacturing steps and to thereby make the assembling easy. The light conducting portions for conducting light from light sources furnished in a control panel to light-emission portions of the control panel are constituted by operating dial light-emission portions, label light-emission portions, a CD insertion hole light-emission portion, and so on. Further, temporarily locking claws for locking the light shielding portions in the control panel temporarily may be formed by integral molding with the light shielding portions to thereby make the assembling easier. Further, light shielding walls for shielding the surroundings of the light conducting portions may be provided in the light shielding portions so that light from the light sources enter only aimed light conducting portions.
