Description
Technical field
The present invention relates to a kind of optical scanner.
Background technology
Fig. 1 is that the optical scanner pedestal and the scanning plane of prior art is not the schematic diagram that copline is settled.
In the scanning means that shows two optics modules, pedestal 10 is mounted with fixing Image Sensor 18, the two side 17 of pedestal 10 is provided with slip axis hole 15 (please refer to Fig. 2), the usefulness of sliding axle 16 arrangements is provided, 16 of sliding axles are to settle thereon for two the portable optics modules (not being shown among the figure) in two optics module scanning means, so that slidably reciprocate capture.Because in the scanning means of two optics modules, include two portable optics modules and an Image Sensor 18 that is fixed on the pedestal 10, add up to three optical facilities when scanning sensing, all relative motion can be arranged each other, as long as therefore have the light path of optical facilities to depart to some extent, then the quality of scanning imagery just is greatly affected; The scanning means of relative single optics module is because of in all optical facilities all the are installed in single optics module, each optical facilities does not have relative motion fully in scanning process, therefore having light path hardly departs from the phenomenon that causes image quality not good, so the position stability degree between each optical facilities of the scanning means of two optics modules just seems very important.In order to improve the position stability degree of Image Sensor 18 and sliding axle 16, so the material that pedestal 10 uses, the stability of the contraction of must expanding is preferable, mainly is to use the sheet metal material at present, if develop the other materials of high stability, also can change the material that uses those high stabilities.So, used the pedestal 10 of sheet metal material, then the outside must be again with shell 11 as outer packaging, increase attractive in appearancely on the one hand, provide scanning glass 12 carrying usefulness on the one hand, the interface between scanning glass 12 and the pedestal 10 also is provided simultaneously.Because very high being not suitable for of the sheet metal hardness of pedestal 10 directly is connected with scanning glass 12.Prior art all can be at pedestal 10 and the scanning glass 12 middle buffer elements that are mounted with, avoid pedestal 10 directly to contact with scanning glass 12, in order to avoid the hardness of pedestal 10 is damaged scanning glass 12, or pedestal 10 and scanning glass 12 separated, as shown in FIG., be that shell 11 connects face 114 carrying scanning glasses 12 with the L type, pedestal 10 and scanning glass 12 are directly joined.The device that pedestal 10 and scanning glass 12 become " copline arrangement " is not seen in this arrangement of prior art.Thus, the position of the Image Sensor 18 above calculating is positioned at pedestal 10 just must be considered to be mounted with the degree of error of buffer element in the middle of pedestal 10 and the scanning glass 12 more.
Fig. 2 is the stereogram of the pedestal 10 among prior art Fig. 1; Pedestal 10 tops carry Image Sensor 18, and there is sidewall 17 both sides, and sidewall 17 is provided with slip axis hole 15 provides sliding axle 16 to settle usefulness.Pedestal 10 is provided with upper limb 14, and upper limb 14 is provided with pedestal fixing hole 103, and the top of the upper surface 142 of the solid pedestal 10 of screw 13 spiral shells is provided.The prior art that had not had is that the upper surface 142 that the upper surface 122 with scanning glass 12 is positioned to upper pedestal airfoil 14 is " coplanar ".
Summary of the invention
The purpose of this invention is to provide a kind of optical precision degree that improves product, simplify the assembling of product and the optical scanner of manufacturing process.
The object of the present invention is achieved like this, and described optical scanner comprises scanning glass, shell and pedestal, and wherein pedestal becomes " copline arrangement " with scanning glass, and the load-carrying unit of scanning glass is mainly at shell.
Owing to adopt said structure, scanning glass promptly is the calculating datum level of optical element relative position, because light source irradiation is further processed to the later reflection ray of scanning object, settle the position of optical element promptly is closely related position in scanning plane, therefore when pedestal and scanning glass are copline, being placed in the optical element on the pedestal such as the position calculation of Image Sensor and sliding axle has just seemed simply, as long as the upper surface with upper pedestal airfoil serves as to calculate datum level, settle optical element, needn't consider the scale error of pedestal composition element in addition, can improve the accuracy of product like this, also simplify the manufacturing and the assembling of entire product, improve the optical precision degree of entire product, obtain preferable image output.
