Abstract
A self-lighting type push-button input device according to the presently disclosed subject matter can include a button base portion formed of a transparent material. Holes can be formed in predetermined positions of the button base portion, and spring portions can be formed integrally with the holes by molding transparent silicone rubber with a light diffusing agent incorporated therein. The button base portion serves as a light conducting portion, and the spring portions can uniformly diffuse the light distributed thereto by the light conducting portion, whereby lighting can be effected by a reduced number of light sources, effecting a reduction of size and cost.
