Abstract

The invention relates to a selecting and transmitting power supply device of an optical mouse with double power supplies and a detecting method, wherein the inner portion of an optical input device of an optical mouth and the like is provided with double power supplies, and one of the double power supplies is selected as a light-emitting power supply through the reflecting intensity of the power supplies, after a first surface characteristic value and a second surface characteristic value which are received by a signal-comparing unit of the invention are compared, and the signal-comparing unit outputs comparing signal and conveys the comparing unit to a switch control unit for controlling the switches of a laser-emitting unit and an optical emitting unit and deciding whether the laser-emitting unit or the optical emitting unit is selected as a light-emitting power supply.

Description

technical field [0001] The invention relates to a device for selecting a light source for emission and a detection method thereof, in particular to an optical input device with dual light sources inside, such as an optical mouse, etc., and a detection method thereof. Background technique [0002] The traditional optical mouse only has a single light source as the emission source. According to the different light-emitting modules installed, there are two types of visible light and invisible light-emitting modules. Visible light can be like infrared light, and invisible light can be like laser light. Therefore, using the above two different The light-emitting module can produce an optical mouse with two different light sources. [0003] In the application technology of dual light sources, China Taiwan Patent Publication No. 586607, the patent document titled "A Device for Sharing Dual Light Sources", has disclosed that dual light sources are installed on the electronic device ...
