Description
Technical field
The utility model relates to a kind of computer entry device, refers to a kind of optical mouse especially.
Background technology
Along with the progress of computer software and popularizing of graphic user interface, oneself is widely used in the user interface of computing machine mouse.Existing mouse is generally the mechanical type mouse, it is to drive X and Y direction grating wheel (encoder wheel) by a spin when rolling, light signal by continuous blocking one optical transmitting set between this grating wheel, after photodetector receives, handle by suitable control circuit, get final product the interpretation mouse moving direction, the coupled computer driver can be controlled the direction that onscreen cursor moves again.Yet because the mechanical type mouse must be by ball (for example mouse pad) upward slip on a plane of heaviness, and ball must expose the mouse bottom surface by a circle hole, therefore after the long-time use of process, dust enters mouse inside via the slit between ball and the circular hole easily, influences mouse action.Moreover heavy ball also can increase user's burden.
Existing another kind of mouse is an optical mouse, be by an optical transmitting set (for example light emitting diode) emission light beam, light beam is after a special mouse pad with light and shade striped reflects, after promptly receiving by a photodetector (a for example inspection optical diode), in the time of can moving by mouse, have the light and shade striped mouse pad reflection variation and interpretation moving direction and corresponding cursor move.
Yet above-mentioned early stage optical mouse needs special mouse pad, can not use on general closed planar, causes greatly inconvenience of user.Progress along with photodetector, this light signal can be by the photodetector of an array formula, for example CMOS (Complementary Metal Oxide Semiconductor) image sensing component (CMOS IMAGE SENSOR) or Charged Coupled Device (CCD) detect, and the light signal change in pattern of interpretation different time can be learnt mouse moving direction.
As Fig. 1, be the sectional view of an existing optical mouse.This optical mouse has an optical transmitting set 10 (for example light emitting diode) emission one light beam, and this light beam has reflecting prism (lightemitting prism) 12 leaded lights of special shape via one and incides on the working face 100 with low incident angle.Figure as can be seen thus, in incide on the working face 100 with low incident angle in light beam, therefore also can be, or be not complete when smooth on the plane with less reflection angle reflection, also have big diffusion component and reflect toward a photodetector (a for example Charged Coupled Device) 20.This optical mouse has a condenser lens 14 that is positioned on the reflection paths in addition, to adjust the image ratio of folded light beam, cooperate a digital signal processing unit (not icon) that is installed in the housing 30 again, can change by image and judge mouse moving direction and distance.
Yet, in this existing optical mouse, because needs one have the reflecting prism 12 of special shape, as shown in this figure, light must be through behind the secondary reflection, one light beam that is parallel to working face 100 could be directed to one and working face 100 has the light beam of little incident angle, proceeds to photodetector 20 again after primary event and via condenser lens 14.This reflecting prism 12 must carry out the processing in reflection horizon, makes to be difficult for, and owing to the cause that repeatedly reflects, also can cause the loss of light signal.Existing optical mouse also is difficult to adjust resolution.Simultaneously,, yet there is not a preferable mode to combine, therefore fails to give full play to its effect with main frame though optical mouse now has light advantage.
