Embodiment
See also Fig. 1 to shown in Figure 3, the invention provides a kind of optics Dust-proof mouse, comprise a mouse body 1, a photoinduction module 2 and a dustproof sheet 3.
Have an accommodation space 11 in the mouse body 1, accommodation space 11 belows have one and are through to the through hole 12 in mouse body 1 outside by accommodation space 11, and mouse body 1 below has a plurality of foots pad 13.Through hole 12 includes a recessed joint portion 121, and dustproof sheet 3 is fixedly arranged on joint portion 121.Foot pad 13 can be avoided the translational surface friction of dustproof sheet 3 or other element and the mouse of mouse below with the mouse bed hedgehopping, causes the abrasion of all multicomponents.
See also Fig. 1 and shown in Figure 4, dustproof sheet 3 is arranged at through hole 12 places of mouse body 1.Dustproof sheet 3 has a transparent panel 31, a first filming layer 32, one second film plating layer 33 and a Printing Department 34.The first filming layer 32 is arranged at transparent panel 31 1 sides, Printing Department 34 is arranged at the first filming layer 32 outboard peripheries, Printing Department 34 has effect attractive in appearance, but and scribble the joint portion 121 of viscose glue connecting through hole 12 in the Printing Department 34, and dustproof sheet 3 is pasted on the mouse body 1.In the present embodiment, transparent panel 31 is the acryl panel, but is not limited, and also can select the panel of different high light-transmitting materials, such as face glass etc.Therefore the purpose of dustproof sheet 3 plated films is to promote the transmittance of dustproof sheet 3, if need further promote its transmittance, then can plate one second film plating layer 33 away from a side of the first filming layer 32 at transparent panel 31 again again.The refractive index of the first filming layer 32 and the second film plating layer 33 is less than the refractive index of transparent panel 31.In the present embodiment, the material of the first filming layer 32 and the second film plating layer 33 is silicon dioxide, titania or bifluoride magnesium.
Optical mouse is that first optical transmitting set 21 by photoinduction module 2 emits light into optical frames group 22 when the sensing mouse moves, and after optical frames group 22 interior process Multi reflections and refraction, leave optical frames group 22, then pass again dustproof sheet 3 and arrive mouse translational surface back reflections and return, pass once again that dustproof sheet 3 is laggard to enter optical receiver 23.Whereby, photoinduction module 2 can be obtained the image of mouse translational surface, relends to be moved by mouse to cause the change situation of obtaining image to be judged the movement of mouse.
When light enters into another medium from a medium, have part reflection and partial penetration at interface.For the acryl panel, when air enters the acryl panel, have 4% light when light and be reflected, 96% light penetrates, and when the light of reflection is too much, just can forms some harmful veiling glares, and then affect optical receiver 23 obtaining for image.
If small particle is arranged in the material when light passes transparency material, then photon then can to all the winds spread out, this phenomenon is called scattering phenomenon, and the generation of scattering phenomenon can cause the loss of photon and the phenomenon such as interfere with each other, and then affects optical receiver 23 obtaining for image.
When light passes dustproof sheet 3 twice back and forth, to have met four secondary reflections together in dustproof sheet 3 upper and lower surfaces, and passed dustproof sheet 3 for twice and cause consumption, meeting reduces optical receiver 23 for the accuracy rate of obtaining of image so that light transmittance is crossed low and reflectivity is too high.
In order to increase the penetrance of dustproof sheet 3, therefore dustproof sheet of the present invention 3 surfaces have film plating layer, and according to electromagnetic basic theories, the penetrance of different medium with reflectivity calculating formula is: (by medium n1 vertical incidence to n2)
Penetrance=1-reflectivity
The material that general optical coating plates is MgF
2Its refractive index=1.35; The refractive index of air=1.0; Acryl refractive index=1.5, the substitution following formula can get:
1. light enters acryl by air
Reflectivity=4%
Penetrance=96%
2. light enters acryl after entering film plating layer by air again
Reflectivity=0.3%
Penetrance=99.7%
From the above, the dustproof sheet 3 with film plating layer can significantly promote its penetrance, reduce the impact that the reflection veiling glare causes optical receiver 23 Image Acquisition.
In addition, can be designed for the thickness of film plating layer, so that the catoptrical phase differential that light produces respectively when passing the film plating layer upper and lower surface is 1/2 wavelength (anti-phase), make the twice reflected light produce destruction interference, thereby the counteracting reflected light reaches antireflecting effect.
The making of film plating layer is take physical vapor deposition as main, its method for Coating Materials by the solid-state gaseous state Huo From attitude that is converted into, the material of gaseous state Huo From attitude passes through the space by evaporation source, arrives at transparent panel 31 surfaces, deposition and form gradually film plating layer.In addition, in order to allow film plating layer that high-purity can be arranged, so coating process is in high vacuum (10
-5Torr) finish under the environment
Dustproof sheet 3 of the present invention is fixed in mouse body 1 from the outside with bonding method, when dustproof sheet 3 runs into scratch or the problem such as dirty, dustproof sheet 3 can be pulled down again and change, and makes dustproof sheet 3 keep the effect that optimal light penetrates.
The present invention is provided with a dustproof sheet 3 between photoinduction module 2 and mouse body 1 outside, can prevent that the filths such as dust are attached to photoinduction module 2, cause photoinduction module 2 to obtain to some extent error of surface image, reduce the sensitivity of the vernier on the display screen and the problem of accuracy.
The above only is the present invention's preferred embodiment wherein, is not to limit practical range of the present invention, and namely all equalizations of doing according to claim scope of the present invention change and modify, and are all claim of the present invention and contain.
