Tension stress reflecting optics stationary installation
(1) technical field
The relevant a kind of tension stress reflecting optics stationary installation of the present invention, particularly relevant for a kind of with the face tension type with the eyeglass stationary device.
(2) background technology
Along with the whole trend of day by day dwindling with component size of scanner, dwindling for dwindling of scanner overall volume of the various elements of lens set has great help.And because in scanner, advancing of light is the influence that is subjected to each lens and each reflecting optics in the lens set, (the unnecessary change or the utmost point needs the reflecting optics of planarization to produce the phenomenon of bending such as the focal length generation of lens so if the lens of leading opticpath or reflecting optics have any non-default situation generation ... Deng), the scanning quality of scanner must be affected.
With the known reflecting optics stationary installation of Fig. 1 is example, and traditional mode that grips often is reflecting optics 3 to be held on the breasting face 7 of carrier 5 with holding piece 1; For reflecting optics 3 and carrier 5 is thoroughly fixing in case slide, and holding piece 1 nature need clamp an opposite planar 9 of breasting face 7, just can reflecting optics 3 clampings are firm.Because of need the lateral location of reflecting optics 3 is fixed again, make it to connect to another breasting face 11, so need to make a groove plane 13 at the side of opposite planar 9, an end that makes holding piece 1 is by the mode that clamps groove plane 13, gives the lateral pressure of reflecting optics 3 and reaches to reflecting optics 3 side fixed effects.
Yet I haven't seen you for ages causes thickness d as shown in fig. 1 for the method for clamping of this kind holding piece 1, makes the component size size of reflecting optics stationary installation be not easy to carry out downsizing; Like this, mirror elements is because of omitting, and its volume just can produce the interior part volume of scanner of certain deal, and then the volume-diminished of scanner element is produced certain restriction.
In addition, because this kind is in the mode of holding piece 1 clamping reflecting optics 3, as easy as rolling off a log because of holding piece 1 be with the mode of a contact or the line contact reflecting optics 3 of extruding, the acting force of holding piece 1 clamping reflecting optics 3 is only accumulated on the part of point-like or wire, and then because the too concentrated reflecting optics 3 that causes of acting force produces distortion, cause the light of penetration eyeglass 3 reflections to be offset thereupon, make the former state of scanner light that receives and the contribution that is scanned not conform to, the performance of scanner and the reliability of scanner are caused bad influence.
(3) summary of the invention
Therefore, the purpose of this invention is to provide and a kind ofly scanner volume is dwindled and prevent scanner reflecting optics bending and reflecting optics stationary installation that the probability of scanning document accuracy step-down is reduced.
A kind of tension stress reflecting optics stationary installation is provided according to an aspect of the present invention, is characterized in, comprising: a carrier has a breasting face; One eyeglass; One thin slice fixator, the mode that contacts with face is held on this eyeglass on this breasting face of this carrier.
A kind of lens fixing apparatus is provided according to a further aspect of the invention, be characterized in, comprise: one has the thin slice of tension stress, its area size is enough to coat an eyeglass, this thin slice two ends longitudinally respectively has at least one screw, in order to cooperate screw to be fixed at an eyeglass carrier, make this eyeglass fixedly be carried on this eyeglass carrier by this.
Provide a kind of assemble method of fixing len according to another aspect of the invention, be characterized in, comprise: with a lens-bearing on an eyeglass carrier; Be coated on this eyeglass with a thin slice; And fix this thin slice on this eyeglass carrier.
Adopt such scheme of the present invention can reduce the thickness of scanner reflecting optics stationary installation, reducing the inner space of scanner, and then reduced scanning device overall volume; Under the prerequisite that reflecting optics and carrier are fixed well, clamp reflecting optics by thin slice with the face tension type, and the fixation reflex eyeglass is on carrier, the reduced down in thickness that makes the reflecting optics stationary installation is to minimum.
In addition, adopt such scheme of the present invention can stablize the accuracy of scanner scans master copy file, tortuous and then impel the signal of master copy file to produce wrong probability to prevent scanner because of reflecting optics; So the mode of reflecting optics with face stress is fixed on the carrier with fixing thin slice, reflecting optics can be out of shape because of the fixed form of a stress or uniaxial stress, make anti-mirror to the light of master copy file get back to signal receiver according to predefined paths, do not produce and do not have any deviation improperly, reach to the purpose of stablizing scanner scans master copy file accuracy.
And, efficient when the present invention can speed the assembling of reflecting optics stationary installation, under the well secured prerequisite on carrier of reflecting optics, cause fixedly thin slice can be different spare parts with carrier, after so fixedly thin slice, reflecting optics and carrier can be gone ahead of the rest and be completed respectively, row assembling again, when designs fix thin slice big or small, needn't require excessively fixedly whether thin slice is very identical with the size of reflecting optics and carrier, that is fixedly thin slice does not need the goodness of fit of excessively requirement and carrier when design; And when assembling, also the fixed form because of fixing thin slice is rather simple, so can reach the purpose of efficient when promoting the assembling of reflecting optics stationary installation, and because of the goodness of fit of thin slice and carrier and need not special requirement, the tolerance that thin slice and carrier size misfit can improve, and can promote naturally for the making yield of retaining element.
Adopt the present invention also to reduce the cost of scanner reflecting optics stationary installation, under the well secured prerequisite on carrier of reflecting optics, clamp reflecting optics by fixing thin slice in the mode of face stress, fixedly the size of thin slice is as long as partly be slightly larger than the area of reflecting optics, can fix reflecting optics, so do not need as known reflecting optics stationary installation, the size of stationary installation must be many greater than the reflecting optics size, like this, reflecting optics of the present invention fixedly thin slice just can dwindle and reduce cost because of overall volume.
In addition, the present invention can reduce the weight of scanner reflecting optics stationary installation, known reflecting optics must be held on the carrier by holding piece, and the material of holding piece must have on-deformable material for structure is harder, so can have the weight of certain deal and be difficult for weight reduction.Fixedly thin slice of the present invention can be under the well secured prerequisite on carrier of reflecting optics, clamp reflecting optics by fixing thin slice in the mode of face stress, fixedly the material of thin slice is not limited to hard, on-deformable material, can fix reflecting optics, so do not need as known reflecting optics stationary installation, can produce the weight of certain deal, like this, fixedly thin slice just can be because of the change weight reduction of material for reflecting optics of the present invention.

(5) embodiment
Below the description of reflecting optics fixture structure of the present invention is not limited the scope of patent protection of reflecting optics stationary installation.The prior art that the present invention continued to use is only done quoting of emphasis at this, to help elaboration of the present invention.And drafting to scale of relevant indicators, its effect is only in performance architectural feature of the present invention.
Shown in Fig. 2 A, first preferred embodiment of reflecting optics stationary installation of the present invention is a fixing thin slice 15; Its vertical view is the fixedly thin slice of strip promptly as shown in FIG., and its two ends have a hole 17 respectively in order to hold screw.
Shown in Fig. 2 B, promptly be fixing thin slice 15 to be passed hole 17 with screw 19 be fixed in front elevation on the carrier 21,23 of reflecting optics are to be fixed on the breasting face 25 of carrier 21 with the clamping of carrier 21 by fixing thin slice 15.Because when producing fixedly thin slice 15, but it can be designed to the size of elastic telescopic and suitable this reflecting optics 23 of clamping, and fixedly thin slice 15 has suitable flexible material, so having under the situation of suitable tightness, just can cause the acting force of the F1 direction of arrow as shown in FIG..
Fig. 2 C is a side cutaway view of the present invention, and fixedly thin slice 15 is fixed in reflecting optics 23 on the breasting face 25 of carrier 21 by screw 17, because the acting force of F1 direction has been arranged, makes that fixedly thin slice 15 clamps reflecting optics 23 with the acting force as the F2 direction of arrow.The acting force of arrow F2 be evenly distributed in reflecting optics 23 on, the acting force that puts on the reflecting optics 23 is presented in the mode of face stress, can not cause the distortion of reflecting optics 23, can prevent that scanner is tortuous and then impel the signal of master copy file to produce wrong probability because of reflecting optics, to stablize the accuracy of scanner scans master copy file.
Fixedly the thickness of thin slice 15 is minimum also can be clear that reflecting optics of the present invention in Fig. 2 C, the thickness d of the reflecting optics stationary installation of known techniques is about 2~3mm, reflecting optics of the present invention is thin slice 15 thickness d fixedly ' scope is between 0.1~0.3mm, can obviously reduce scanner reflecting optics stationary installation thickness, with the inner space of minimizing scanner, and then reduced scanning device overall volume.
Because fixedly thin slice 15 of the present invention is shaped as sheet, so as long as the fixing original material of thin slice 15 shape of laminating earlier, fixedly the strip of thin slice 15 and hole 17 are cut out to create and promptly be can be made into a stationary installation in the mode of cutting out again, need not must be through processes such as molding or sculptures as known techniques, can finish fixedly thin slice 15 of the present invention, not only the processing procedure of stationary installation is easy to be many, also have the not material of easy fracture of elasticity because of material can be plastic cement or hot telescopic material (as Mylar) etc., cost reduces naturally; And the reflecting optics of the present invention fixedly size of thin slice 15 needs only the area that partly is slightly larger than reflecting optics 23, can fix reflecting optics 23, do not need the size of stationary installation as known reflecting optics 23 stationary installations many greater than reflecting optics 3 sizes usually, the present invention fixedly overall volume of thin slice 15 can reduce the cost of stationary installation because of dwindling oneself.
And compare by Fig. 1 and Fig. 2 C of the present invention of known techniques, reflecting optics stationary installation known among Fig. 1 must be by holding piece 1 clamping reflecting optics 3 on carrier 5, the material of holding piece 1 must be difficult for alleviating its weight so can have the weight of certain deal for the harder on-deformable material of structure.Fixedly thin slice 15 of the present invention can be under reflecting optics 23 well secured prerequisites on carrier 21, clamp reflecting optics 23 by fixing thin slice 15 in the mode of face stress, fixedly the material of thin slice 15 is not limited to hard, on-deformable material, can fix reflecting optics 23, so do not need as known reflecting optics stationary installation, can produce the weight of certain deal, like this, the fixedly thin slice 15 of reflecting optics 23 of the present invention just can be because of the change weight reduction of material.
In addition, shown in first embodiment of the present invention Fig. 2 C, cause fixedly thin slice 15 is different spare parts with carrier 21, as long as after fixedly thin slice 15, reflecting optics 23 distinctly complete with carrier 21 in advance, on carrier 21, produce two with fixing thin slice 15 holes 17 corresponding screw holes 27, again screw 19 is fixed in the screw hole 27 by hole 17, can reflecting optics 23 is well secured on carrier 21; Do not need excessively to require fixing thin slice 15 whether very identical, can assemble and finish, and speed the efficient of reflecting optics 23 stationary installations when assembling with both sizes of reflecting optics 23 and carrier 21.And the degree of depth control of being fixed in screw hole 27 by screw 19 also can be controlled quality to guarantee that reflecting optics is fixed for the elasticities that fixing thin slice 15 is fixed.
By the present invention in the fixing mode of thin slice fixation reflex eyeglass, do not stablize outside the degree of stability of scan manuscript file because of mode fixation reflex eyeglass only with face stress, also can reduce cost, the efficient when speeding the assembling of reflecting optics stationary installation of scanner reflecting optics stationary installation thickness, weight, minimizing stationary installation, and the degree of depth control that can be fixed in screw hole by screw, control quality for the fixing fixedly elasticity of thin slice to guarantee that reflecting optics is fixed.
Certainly, but the present invention is thin slice except the material adaption demand and changing (as plastic cement or Mylar) fixedly, its shape also is not limited to strip, and also can as the fixedly thin slice 29 of Fig. 3 A, add system side width and make hole 31 in side, pass fixing thin slice 29 is fixed in for screw and strengthen fixation degree on the carrier; Even as Fig. 3 B, the part that contacts with breasting face 35 in fixing thin slice 33 adds two column stripeds 37 of system, strengthening the fixedly physical strength of thin slice 33, and become the fixedly thin slice 33 as Fig. 3 C.And directly carrier 41 is wrapped the mode of reflecting optics 43 as Fig. 3 D with fixing thin slice 39, or as Fig. 3 E with fixing thin slice 45 with carrier 47 parcels with fixation reflex eyeglass 49, and add the fixedly mode of thin slice 45 elasticities of a screw 51 controls, all be the applicable scope of the present invention.
