Description

Mouse and optical texture thereof

Technical field

The utility model relates to a kind of mouse and optical texture thereof, refer in particular to a kind of optical texture that has coherent source and omit lens element, in order to reduce cost and to dwindle overall volume and the sensing performance of promoting mouse, improve its sensitivity, it can be worked on different surfaces.

Background technology

In the technical field of optical mouse, its cardinal principle is to use a coherent source (as light emitting diode) to send an incident light to desktop or mouse pad, and judge that by the reflected light that on using planar, produced of acquisition the inhomogeneous or nick that its surface has is protruding, with the start situation of control optical mouse, as disclosed in the Taiwan patent application case number No. 093205855.

See also Fig. 1, be the cut-open view of the optical texture of known optical mouse.Wherein optical texture 1a is arranged in the shell 2a of optical mouse, and it comprises a lens mount 3a, a LED element 4a and an image sensing element 5.Wherein this lens mount 3a is arranged at the bottom of optical mouse shell 2a, and this lens mount 3a is provided with first a lens 31a who corresponds to incident light emission place of LEI element 4a, and second a lens 32a who corresponds to reflected light reception place of image sensing element 5a.The incident light that LEI element 4a is sent refracts to reflecting surface 6a (desktop) via the first lens 31a, after via reflecting surface 6a reflection, forms reflected light.Reflected light transfers to reflected light reception place of image sensing element 5a again via the second lens 32a.

After the incident light of aforementioned LED element 4a is radial sending, just be passed to image sensing element 5a, so light signal can loss in transmittance process through the first lens 31a, reflecting surface 6a and the second lens 32a.Change speech, the incident light that LED element 4a is sent is through lens mount 3a, and can't be passed to image sensing element 5a fully.When a little less than the light signal, the sensitivity of image sensing element 5a and resolution can reduce, and then influence the performance of optical mouse.

Moreover this lens mount 3a involves great expense, and increases the volume of optical texture integral body.

In addition, when aforesaid optical mouse is used on smooth surface, can quite have some setbacks usually, the optical imagery analysis of the computer that passes to, and can't the accurate localization mouse moving.

Therefore, above-mentioned traditional optical mouse still exists problem to be solved and improves part.

By above-mentioned reason, I am according to abundant for many years practice experience, am that the spy concentrates on studies and cooperates the utilization of scientific principle, propose a kind of reasonable in design and effectively solve the utility model of the problem of known technology finally.
