<P>PROBLEM TO BE SOLVED: To provide an illumination structure for a button switch in which, a light-emitting area of light emitted from the same light source is switched in accordance with an operating state of a switch body. <P>SOLUTION: In the case where a reflection plane 8 is positioned on an optical path of a light source 2, through reciprocation of a first light guide 5 with a pressing operation of a button, light emitted from the light source 2 is reflected on the reflection plane 8 and guided inside of the first light guide 5 and a first illumination opening 9a is emitted with light emitted from an emission plane 5a. In the case where the reflection plane 8 is positioned out of the optical path of the light source 2, light emitted from the light source 2 is reflected in a reflection area 6b and guided inside of a second light guide 6 and a second illumination opening 9b is emitted with light emitted from an emission plane 6c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
