The utility model comprises a transparent document platform, a CIS elastic loading device, at least one driving shaft and a driving device, wherein, the transparent document platform is arranged above a machine table and used for placing a document; the CIS elastic loading device is closely attached to the lower surface of the transparent document platform and used for reading the image of the document; the driving shaft supports the CIS elastic loading device to make the CIS elastic loading device closely attached to the transparent document platform; the driving device is connected with the CIS elastic loading device to make the CIS elastic loading device move from one end of the document to the other end of the document to complete the reading the document imaging.
Description
The utility model relates to the platform-type optical scanner of a kind of CIS type.
The image fetch device that scanner is used always have Charge Coupled Device (CCD) (CCD) and contact-type image sensor (Contact image sensor, CIS).Platform-type scanner uses the electric charge lotus root to close sensor mostly, because its depth of field is long, so the image quality of scanning is better.And the depth of field of contact-type image sensor is short, and resolution is not high, so generally be applied on facsimile recorder or the hand held scanner.Yet the shortcoming of using Charge Coupled Device (CCD) is that the required light path of CCD and lens set is longer, so the volume of scanner is difficult to dwindle.With regard to dwindling body, the contact-type image sensor is a feasible selection, especially it can be applied to the platform-type scanner of low order.Main because of contact-type image sensor height modularity, easy to assembly so volume is little, be easy to reach reduced volume, simplify the purpose of inner structure.
Yet, the CIS module not being applied to platform-type scanner as yet at present, its main cause is to overcome the short restriction of the CIS module depth of field.Because the depth of field of CIS module has only 0.3mm, in case manufacturing tolerance is excessive, or the deformed element of board, file is left in its field depth, and influence the quality of image.
Fundamental purpose of the present utility model is to utilize a bogey with flexible member, with carrying CIS module, and make it to be close to the transparent file platform and move, can guarantee that so just file is positioned at the field depth of CIS, the image that makes scanning is reason manufacturing tolerance or body deformation and blur not.
Another purpose of the present utility model is to propose a kind of modular CIS elastic carrier device, applicable to the scanner of arbitrary drive mechanism, so that the assembling of scanner is easy, can further reduce the cost of making and keeping in repair.
For achieving the above object, the utility model proposes a kind of platform-type optical scanner and comprise: transparent file platform, CIS elastic carrier device, at least one transmission shaft and drive unit, wherein, the transparent file platform is positioned at the top of board, is used to place file; CIS elastic carrier device is close to the surface below of transparent file platform, in order to read the image of file; Transmission shaft makes CIS elastic carrier device be close to the transparent file platform to upper support CIS elastic carrier device; Drive unit is connected with CIS elastic carrier device, makes CIS elastic carrier device shift to the other end by file one end, reads to finish document image.
The utility model has the advantages that because bogey has flexible member, the CIS module is close to the perpendicular displacement of transparent file platform, keep certain distance between module and file, the surface of contact of being close to the transparent file platform at bogey installs spacer block additional, can make moving steadily of CIS elastic carrier device.Because CIS elastic carrier device of the present utility model is a modular element, applicable to the plat form type scanning apparatus of any transmission shaft structure, thus easy to assembly, more can simplify the inner structure of scanner, dwindle body.
Below in conjunction with accompanying drawing in detail preferred embodiment of the present utility model is described in detail.In the accompanying drawing:
Fig. 1 is the following view and the side cut away view of the platform-type optical scanner of first embodiment of the present utility model;
Fig. 2 is view and a side cut away view under the platform-type optical scanner of second embodiment of the present utility model;
Fig. 3 is view and a side cut away view under the platform-type optical scanner of the 3rd embodiment of the present utility model.
First embodiment of the present utility model sees also Fig. 1.Fig. 1 shows the simplest structure, utilizes CIS elastic carrier device of the present utility model to be assembled on one single transmission shaft.As shown in the figure, platform-type optical scanner of the present utility model mainly comprises: a transparent file platform 107, one CIS elastic carrier devices 102, one transmission shafts 105, and a drive unit 109.
CIS elastic carrier device in the utility model is a modular element, and the gear frame structure when it is installed can have many kinds possibilities.Fig. 2 just is the design of a pair of transmission shaft.As shown in the figure, unique different of Fig. 2 and Fig. 1 are changing transmission shaft 202 into two, and are positioned at the both sides of board.As long as and drive unit 203 is installed in a wherein side of a transmission shaft.Itself do not need change as for CIS elastic carrier device 204.Certainly, if will with the patrilineal line of descent with only one son in each generation moving axis support be fixed on instead cover also passable.As shown in Figure 3, the support 303 of transmission shaft 305 is fixed on the loam cake 302 of board 301.CIS elastic carrier device 304 itself does not need to change yet.
In a word, CIS elastic carrier device of the present utility model is constructed applicable to multiple gear frame, and transmission shaft can be single, is assembled in the middle of the board, or two, is assembled in the board both sides, perhaps transmission shaft be assembled in base or on cover., can guarantee that just file is positioned at the field depth of CIS module, and reach the stable purpose of image quality as long as but the transmission shaft balance to upper support CIS elastic carrier device, makes it to be close to the transparent file platform.
