Embodiment Construction

[0015] Please also refer to FIG. 3 to FIG. 5 for implementation status of a preferred embodiment of the present invention. Wherein, Fig. 3 shows that the bottom of the optical mouse 1 is provided with an opening 10, and a group of optical mechanisms are arranged in the inner space group, the optical mechanism of the present embodiment includes a light source device 11, a light guide device 12, a light sensor 13, and a light absorbing layer 14 . Among them, the light source device 11 is preferably a light-emitting diode grain (LED Die), or can be other equivalent illuminants; the light-absorbing layer 14

[0016] It is preferably black paint, which is directly coated / adhered on the surface to absorb the light source. Of course, the light-absorbing layer 14 can also be formed through surface treatment on the surface to absorb the light source.

[0017] As shown in Figure 3, the incident light source I projected by the light source device 11 of this embodiment 1 is parallel to ...

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...
