Description
Technical field
The invention relates to a kind of lens shape structure and its lens fine regulation structure, be applicable in the optical system of scanner,, and provide the fine setting and the function of fixed lens position simultaneously in order to the lens fixed sturcture of the different configuration designs of correspondence.
Background technology
Along with advancing by leaps and bounds of computing power, and the high development of internet and multimedia technology, image reading apparatus (Scanner) has now become the indispensable standard of personal computer and has been equipped with.General falt bed scanner commonly used comprises an optical system and a drive mechanism, drive optical system (Chassis) by drive mechanism, make the optical sensor (Sensor) of optical system inside progressively receive the image of paper surface, and image transitions is become electronic signal output.
Please refer to Fig. 1, it is the diagrammatic cross-section of common optical system.Optical system 100 mainly can be divided into carrying box body 110, light source 120, catoptron 130, lens 140, optical sensor 150.When the drive of optical system 100 by drive mechanism (not drawing), and when graphic left and right directions moves horizontally, light source 120 is by the optically focused of concave mirror 122, and 124 surfaces to file 10 that emit beam, and after the surface reflection via file 10, make light 124 enter and receive slit 112, pass through the reflection one by one of a plurality of catoptrons 130 again after, the refraction that sees through lens 140 focuses on, and is received by optical sensor 150 at last.
Please equally with reference to figure 1, ordinary skill is the mode of surveying by people's wage adjustment, adjust the resolution of the image scanning of optical system 100, therefore, behind the position of stationary mirror 130, must adjust the relative position between lens 140 and the optical sensor 150 simultaneously, to obtain the better images scanning resolution.Because common optical system 100 is among carrying box body 110, embedding hole 144 with lens fixed sturcture 142, and lens 140 are inserted among the embedding hole 144, the mode of surveying with people's wage adjustment is again adjusted the object distance and the image distance of lens 140 along the axis direction of lens 140.Yet lens fixed sturcture 142 only can provide the fine setting of lens 140 on single axis direction, and the fine setting on other direction but can't be provided.
Please equally with reference to figure 1, because carrying box body 110 is normally with the plastics injection molding, or the mode of die cast metal makes, under the uneven situation of mold cools down, to make the shrinkage factor of lens fixed sturcture 142 differ, cause the aperture size in embedding hole 144 to produce change a little.Therefore, when lens 140 are inserted embedding hole 144, lens 140 can't be located on original path of light 124 exactly, and the outgoing path that makes light 124 enter behind the lens 140 is offset, thereby reduce the quality of the image scanning of optical system 100.
Please also refer to Fig. 1 and Fig. 2, wherein Fig. 2 is the lens fixed sturcture of Fig. 1 and the decomposing schematic representation of lens.Lens 140 are made up of an at least one lens body 146 and a lens housing 148, and wherein lens body 146 correspondences embed the embedding hole 149 of lens housings 148 and form lens 140.Then, again among the embedding hole 144 with lens 140 corresponding embedding lens fixed sturctures 142, with positioning lens 140.The section shape of the lens housing 148 of ordinary skill all is made into circle, because lens housing 148 also adopts the mode of plastics injection molding or other processing to make, under the uneven situation of mold cools down, make the shrinkage factor of lens fixed sturcture 142 differ, will cause the size of the interior external diameter of lens housing 148 to change.Therefore, when lens 140 correspondences are embedded in embedding hole 144, make lens body 146 to be located in exactly on original path of light 124 equally, the outgoing path of causing light 124 to enter after the lens body 146 is offset, thereby reduces the quality of the image scanning of optical system 100.
Please also refer to Fig. 1 and Fig. 2, adjusting lens 140 to the appropriate location, ordinary skill is the position that fixes lens 140 with fixing glue, and waits for the time that fixing glue is solidified, and will prolong the production time of optical system 100.In addition, because after fixing glue solidifies, the variation of its volume will be offset the original position of lens 140 a little, cause the outgoing path of light 124 to be offset, thereby the quality of the scan image of reduction optical system 100.
In sum, common lens fixed sturcture only can provide the fine setting location of lens on single axial, and because the uneven influence of mold cools down, the size of the interior external diameter of the embedding hole of lens fixed sturcture and lens housing will be changed, add the stereomutation after fixing glue is solidified, and be offset the original position of lens a little, therefore, common lens fixed sturcture positioning lens exactly thereby reduces the image scanning quality of optical system in preferable light path position.In addition, wait for solidifying the time of being wasted of fixing glue, will prolong the production time of optical system, and reduce the throughput rate of optical system.
Summary of the invention
The object of the present invention is to provide a kind of lens shape structure and lens fine regulation structure thereof, change the lens housing with circular external form of ordinary skill, correspondence is designed to different external forms, in order to meet the lens fixed sturcture of different designs, and its lens fine regulation structure can increase to the fine setting direction of lens two dimension or three-dimensional, in order to position to the suitable light path position of fine setting lens, and the image scanning quality of raising optical system.And after finishing fine setting, positioning lens and shorten production time of optical system fast is to improve the throughput rate of optical system.
Based on above-mentioned purpose of the present invention, the invention provides a kind of lens fine regulation structure, it is by outer frame, first connecting portion, second connecting portion and fastener constitute, wherein outer frame has an embedding hole, it is in order to allow the lens of optical system embed, in addition, first connecting portion is connected in the outside surface of outer frame, second connecting portion then is disposed at the carrying box body inside of optical system, the mode that moves by opposite planar between first connecting portion and second connecting portion, make the position of lens be able on two-dimensional directional, finely tune to suitable light path position, and after finishing fine setting, fix relative position between first connecting portion and second connecting portion with fastener, with the position of fixed lens.
The present invention is the lens housing that changes the circular section of ordinary skill, and the lens housing is made into various different profiles, in order to the lens fixed sturcture of the different configuration designs of correspondence.In addition, more utilize the lens housing of different configuration designs, form first connecting portion of lens fine regulation structure simultaneously, and corresponding design is formed at second connecting portion of the carrying box body of optical system, fix after the relative translation between the connecting portion and second connecting portion but making wins, in order to the position of fine setting and fixed lens on two dimension or three-dimensional.
