Description
Technical field
The utility model is about a kind of scanning means, and especially about a kind of scanning means with file pressing component, and the scanning platform that pressing assembly is configured to be lower than scanning means is suppressed file.
Background technology
In traditional automatic paper conveying apparatus, utilize roller to come feed documents to pass through scanning window usually, the scan module that is positioned at scanning window below with supply comes the image of scanning document.The quality of scanning of document image is relevant with the depth of field of scan module.File during the big more depth of field allows to present can be smooth in scanning window fully, and the file during the more little depth of field does not then allow to present more is away from scanning window.
When file passed through scanning window, for effective control documents drops in the field depth of scan module, it was to utilize roller to come the contact scanning window that a kind of traditional scanner is arranged.When file passed through scanning window as yet, roller and scanning window were done sliding friction, and when file passed through scanning window, roller and file were done rolling friction, and file and scanning window are done sliding friction.In the case, the wear extent of roller and the wear extent of scanning window are all quite big, influence quality of scanning easily.And when file thickness thickening, file may be difficult for entering in the middle of roller and the scanning window, and can't finish fed with programs.Therefore, known technology normally utilizes elastic force that file is pushed away toward scanning window in the depth of field of scan module for the document control in will presenting as much as possible.No matter be to use flat board or roller to suppress file,, the file by scanning area is attached on the scanning window fully because the contact area of dull and stereotyped and file is too big.Particularly under the situation of using contact-type image sensing module, quality of scanning is easier to be affected, and traditional flat board or roller also just can't satisfy user's demand.
Perhaps, the scanning window that has is not have glass and be the hollow out state.At this moment, produce the assembly that rubs with roller and just become scan module.Therefore, the known practice has been quickened the wearing and tearing of roller and scanning window or scan module, and then influences follow-up image scan quality.
The utility model content
Therefore, the purpose of this utility model provides a kind of scanning means with file pressing component, wherein be to utilize the pressing assembly that is positioned at the scanning position downstream to suppress file, reducing the friction between pressing assembly and the scanning platform, and effectively control the distance between control documents and the scanning platform.
For reaching above-mentioned purpose, the utility model provides a kind of scanning means with file pressing component, and it comprises transparent platform, scan module, paper feed mechanism, section and pressing assembly.Scan module is positioned at scanning position, is used for seeing through the image that transparent platform is obtained file.Paper feed mechanism is used for passing through scanning position along the direction of transfer feed documents.Section is positioned at the downstream of scanning position, and has low spot, and low spot is lower than the upper surface of transparent platform.Pressing assembly is relative with section, is used for limiting the distance between file and the transparent platform.
For foregoing of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Embodiment
Fig. 1 shows the schematic diagram according to the scanning means of the utility model preferred embodiment.Fig. 2 shows the schematic diagram corresponding to the pressing assembly of Fig. 1.Shown in Fig. 1 and 2, a kind of scanning means with file pressing component of the present utility model comprises transparent platform 10, scan module 20, paper feed mechanism 30, section 40 and first pressing assembly 50.Scan module 20 is positioned at scanning position SP, is used for seeing through the image that transparent platform 10 is obtained file D.Paper feed mechanism 30 is used for along direction of transfer feed documents D by scanning position SP.Direction of transfer is that the path by paper-feeding channel 32 is defined.
In the present embodiment, section 40 has groove 42, and forms the gap between the low spot LP of pressing assembly 50 and section 40.Perhaps, section 40 also can comprise the inclined-plane, as long as the low spot LP of section 40 is lower than the upper surface 10A of transparent platform 10.
In the present embodiment, section 40 is in abutting connection with transparent platform 10, and in order to make paper delivery more smooth, this scanning means also comprises arrangement for guiding 60.Arrangement for guiding 60 is positioned at the downstream of section 40, and in abutting connection with section 40, is used for leader files D paper delivery.
Fig. 3 shows another example of pressing assembly.For the purpose of explanation, the upper surface 10A with transparent platform 10 extends by imaginary line.In this example, first pressing assembly 50 and the low spot 50A that contacts of file D are equal to the height of the surperficial 10A of the transparent platform 10 that is positioned at scanning position SP.
