ILLUMINATED INPUT DEVICE

摘要

[PROBLEMS] An illuminated input device that is inexpensive, has excellent durability, consumes less electricity, and can cause an illumination section to emit light of a desired color. [MEANS FOR SOLVING PROBLEMS] The illuminated input device has a wiring board (1) having formed on it a predetermined wiring pattern including a fixed contact (1a) of a bush button switch, a metal dome (2) as a movable contact of the bush button switch, a cover sheet (3) for fixing the metal dome, a light emitting diode (4) as the light source, a through-hole (5a) for receiving the metal dome, and a light guide plate (5) for guiding light entering from the light emitting diode (4) to a surface direction and releasing the light to the inside of the through-hole (5a). A colored section (11) is formed at a metal dome fixation section (3a) of the cover sheet (3). White light released into the through-hole (5a) is reflected by the colored section (11) and radiated to the outside from an illumination mark (8a) formed on a key top (8).
