Description
(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.
Tension stress reflecting optics stationary installation of the present invention comprises: a carrier has a breasting face; One eyeglass;
One thin slice fixator; Be characterized in: described thin slice fixator is to have the thin slice of tension stress and have the area size that covers described eyeglass, and wrap lens is held on this breasting face of this carrier to contact also with the eyeglass face.
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.
