Optical sliding mouse possessing rolling ball

Abstract

An optical slide mouse with rolling ball is composed of a shell with a planar bottom having the first opening, a ball in said shell, and a light source in the shell for generating light beam to irradiate said ball, and a control circuit in the shell and having an optical recognizing unit for recognizing the change in reflected light of ball.

Description

technical field [0001] The invention relates to an optical sliding mouse, in particular to an optical sliding mouse with rolling balls. Background technique [0002] Please refer to FIG. 1 , which is a schematic diagram of a known mechanical sliding mouse 10 . As is well known, the traditional mechanical sliding mouse 10 works by sensing the rolling of a ball installed in the housing of the sliding mouse, and a part of the ball is exposed outside the housing and in contact with the outside world (such as a desktop). When the sliding mouse 10 moves on the plane, its ball will roll and thus drive the two rotating shafts of the sliding mouse 10 to rotate. The sliding mouse 10 further includes two sensors for sensing the rotation degrees of the two rotating shafts and converting the rotating amounts of the two rotating shafts into corresponding index signals. The design of the sliding mouse 10 has been widely used for many years, and is still widely used today, so no detailed ...

Problems solved by technology

[0007] Although the above-mentioned optical sliding mouse 20 has indeed solved the problem of bad work caused by dust accumulation on the traditional mechanical sliding mouse 10

But when the plane 26 that the optical sliding mouse 20 touches and operates is a material such as a glass or a special color, the light 27 of the incident plane 26 cannot be completely reflected on the optical recognition unit 42, and then the optical recognition unit 42 cannot A situation in which a continuous frame of the plane 26 is received and thus causes the optical sliding mouse 20 to generate false pointer signals
