Optical mechanism improvement for optical mouse

Abstract

The improve optical mechanism for optical mouse is assembled inside optical mouse, and has one black paint layer painted to the side surface of the light sensor or one other light absorbing layer formed through surface treatment of the said surface to absorb reflected light, which is not projected to the light sensor. The light sensor has increased contrast and raised image judging capacity.

Description

technical field [0001] The invention relates to the improvement of a mouse mechanism, especially an optical mechanism suitable for an optical mouse. Background technique [0002] In the existing optical mouse technical field, the principle is mainly to judge the action of the optical mouse by judging the unevenness or micro-concavity formed on the surface of the application plane (such as a desktop or a mouse pad). [0003] Please refer to FIG. 1 and FIG. 2 for an existing optical mechanism assembled in the inner space of an optical mouse, and a schematic diagram thereof showing that the optical mechanism in an existing optical mouse 5 mainly includes a light source device 51, a light guide device 52, and A light sensor 53 . The light source device 51 can project an incident light source I 2 to the first lens 521 of the light guide device 52 , and reflected by the first prism 523 and the second prism 524 to pass through the opening 50 at the bottom of the optical mouse 5 a...

AI Technical Summary

Problems solved by technology

In this way, the brightness contrast of the light source received by the light sensor 53 will be reduced, making it difficult for the optical mouse 5 to find the existence of unevenness or micro-concave-convex on the reflective surface 6
