Light-source cover and portable device therewith

摘要

A light-source cover 12 for controlling transmission of light from a light source mounted in a portable device is made of an optical material. The front surface 12a of the light-source cover 12 has a knurl finish 21 composed of linear grooves and the back surface 12b thereof has a spin finish 22 composed of ripple grooves. Alternatively, both the front and back surfaces 12b of the light-source cover 12 have knurl finishes 21 composed of linear grooves. Still alternatively, only the back surface 12b of the light-source cover 12 has a knurl finish 21 or a spin finish 22. Thus, the light-source cover evenly diffuses light from the light source with a simple structure and obscures the light source from external view to keep the attractive appearance.
