Abstract
The present invention relates to a photoelectric crystal sliding mouse of double wafers. The present invention is characterized in that the purpose of improving the resolution degree of the mechanical and photoelectric sliding mouse of double wafers can be achieved by matching the design of the width of rasters and raster gaps on raster wheels with the setting of the width and the distance of two wafers sensing photoelectric crystals.
Description
The present invention relates to a kind of slide-mouse, particularly relate to a kind of mechano optical type slide-mouse that is used for, the more double crystal wafer photoelectric crystal sliding mouse of high-res can be provided.
Mechanical optics slide-mouse in the past is to utilize X-axis and two groups of photoelectricity groups of Y-axis, to judge the component displacement of X-axis and Y-axis, every group of photoelectricity group comprises two light-emittingdiodes and two photoelectric crystals, see also Fig. 1, it is the synoptic diagram of one group of photoelectricity group in a kind of slide-mouse of single-chip in the past, photoelectricity group 1 is to comprise: a grating wheel 11, two light- emittingdiodes 12,13 and two photoelectric crystals 14,15, it mainly is the rotation that utilizes grating wheel 11, make photoelectric crystal 14 15 can receive light-emittingdiode 12 unceasingly, 13 light that sent, and be intermittent conducting, borrow work two height potential change that photoelectric crystal produced, judge the angle of 11 rotations of grating wheel, just slide-mouse is at the displacement of X-axis or Y direction.
The structure of above-mentioned slide-mouse has a great shortcoming, and promptly employed part is many in addition, must calculate the appropriate location and the distance of two photoelectric crystals and light-emittingdiode when assembling complexity and assembling, causes great inconvenience.Development through industry, a kind of appearance of twin lamella slide-mouse is arranged again, see also Fig. 2, it is the synoptic diagram of one group of photoelectricity group in the twin lamella slide-mouse, photoelectricity group 2 comprises: grating wheel 21, light-emittingdiode 23 and double crystal wafer photoelectric crystal 25, its principle and above-mentioned single-chip slide-mouse are similar, main difference is the number that is to receive in the photoelectric crystal wafer, become two by one, borrow the change of work photoelectric crystal element, improved the many shortcomings of single-chip slide-mouse element in the past, and because of the distance that receives between wafer fixing, so save trouble on many assemblings location.
But, the professional is in the manufacturing and designing of biplate slide-mouse, suffer from another new difficulty again, it is the problem that resolution can't promote, please cooperate and consult Fig. 3, it is the synoptic diagram of photoelectric crystal in the twin lamella slide-mouse, photoelectric crystal 3 comprises: base 31, transparency cover 33 and two reception wafers 35,37, principle of work because of the twin lamella slide-mouse, be to utilize two " 00 " that receive wafer, " 01 ", " 11 " reach the order pulse wave of " 10 ", judge the displacement of slide-mouse, wherein two of " 00 " state representation receive wafer and are grating wheel and cover, and " 11 " promptly two receive the breach that wafer all is arranged in grating wheel, suppose that two width that receive wafer 35 and 37 are W among the figure, and distance is D between them, then the lattice of grating wheel 39 are apart from being necessary for (2W+D), the lattice of grating wheel are apart from the resolution that directly has influence on slide-mouse, in the slide-mouse of this kind structure, desire improves unique way of its resolution, can only increase the diameter of grating wheel, yet, will increase the volume of slide-mouse thus, so it is a method of attending to one thing and lose sight of another only.
Fundamental purpose of the present invention is to provide a kind of double crystal wafer photoelectric crystal sliding mouse, and it can improve the resolution of slide-mouse.
For reaching above-mentioned purpose, double crystal wafer photoelectric crystal sliding mouse of the present invention is characterised in that the design that it borrows grating and gap width on the outstanding grating wheel, cooperates the width and the distance setting of two wafers of sensor light electric crystal, just can reach the purpose that improves the slide-mouse resolution.
The present invention is described in detail below in conjunction with drawings and Examples:
Fig. 1 is the synoptic diagram of one group of photoelectricity group in the single-chip slide-mouse in the past.
Fig. 2 is the synoptic diagram of one group of photoelectricity group in the twin lamella slide-mouse.
Fig. 3 is the synoptic diagram of photoelectric crystal in the twin lamella slide-mouse.
Fig. 4 is the calcspar of double crystal wafer photoelectric crystal of the present invention.
Fig. 5,6,7, the 8th, the relevant position synoptic diagram of light emission and receiving element cataloged procedure in the double crystal wafer photoelectric crystal of the present invention.
At first, see also Fig. 4, it is the stereographic map of double crystal wafer photoelectric crystal of the present invention, photocell 41 is as the light source that emits beam, after utilizing passing through of light and capture-effect coding via code device 45,, and change the light signal into high electronegative potential signal and send out by the light signal behind light receiving element 43 received codes, borrow the signal of work height potential change, judge the actual displacement of slide-mouse.
Then, see also Fig. 5,6,7,8, it is the relevant position synoptic diagram of double crystal wafer photoelectric crystal light emission of the present invention and receiving element cataloged procedure, above-mentioned photocell can adopt light-emittingdiode 51, and light receiving element can adopt photoelectric crystal 53, as for code device then is grating wheel 55, as shown in Figure 5, more comprise two sensitization wafers 57 and 59 on the photoelectric crystal 53, this moment, light-emittingdiode 51 emitted lights will be because of grating 551 on the grating wheel 55,552 cover, make wafer 57,59 all can't sense light, and present the low-potential state of " 00 "; And it is shown in Figure 6, represent the displacement of grating wheel 55, and rotate an angle that the light that this moment, wafer 57 will receive by grating wheel 55 grid seam 553 is high potential state because of slide-mouse, simultaneously 59 of wafers promptly cause the state of " 10 " because of covering of 552 pairs of light of grating is electronegative potential; Grating wheel 55 rotates an angle again, and as shown in Figure 7, wafer 57 and 59 via grid seam 553 and 554, receives the light signal respectively, and this is " 11 " state; Grating wheel 55 remakes the rotation of an angle, and wafer 57 will be covered by grating 555, and 59 continuation of wafer receive the light signal by grid seam 554, form " 01 " state.
The width of supposing above-mentioned two wafers 57 and 59 is V, need only with the distance setting of two wafers 4V then, the grating of grating wheel and grid seam are made as 2V, can cause " 00 ", " 01 ", " 11 " to reach the variation in regular turn of " 10 " four phases, and the coding of finishing grating wheel moves, so as to obtaining the data of slide-mouse displacement.Compare with mechano optical type twin lamella slide-mouse in the past, two sensing wafers in the past are when " 11 " state, and the sense path of light is to be passed through by same grid seam, and the width that its grating and grid stitch is necessary for two wafer width and its spacing from sum; Two sensing wafers of the present invention are when " 11 " state, the sense path of light is to be passed through by two grid seams, so the width of its grating and grid seam only must be two wafers width and, under the grating wheel of same size, double crystal wafer photoelectric crystal sliding mouse of the present invention can increase the number of grating and grid seam, and higher resolution can be provided.
In sum, the present invention can reach its intended purposes by its disclosed idea really.
