Embodiment
Fig. 1 shows the schematic diagram according to the file scanning device of first embodiment of the invention.As shown in Figure 1, the scanning device 1 of present embodiment comprises console module 10, paper carrier 20 and scan module 40.
Paper-feeding channel 30 has scanning area 32.Paper carrier 20 comprises feed-in mechanism 21, connecting gear 22 and feeds out mechanism 23.
Feed-in mechanism 21 is in order to be fed into file D in the paper-feeding channel 30.Feed-in mechanism 21 comprises feed-in roller 211 and friction component 212, and friction component 212 for example is a friction pad.Feed-in roller 211 and friction component 212 both actings in conjunction are to reach the separation effect that many files can be fed one by one paper-feeding channel 30.
Connecting gear 22 can comprise two rollers 221,222, enters scanning area 32 in order to the file D that sends from feed-in mechanism 21.The direction D1 that connecting gear 22 transmits file D is parallel to the plane of scanning motion 111 that scanning platform 11 is arranged in scanning area 32.In this embodiment, file D is transmitted along the tangential direction of the cramping point between roller 221 and 222.
Feed out mechanism 23 and can comprise two rollers 231,232, present out paper-feeding channel 30 in order to the file D in future self-scanning district 32.In the present embodiment, the horizontal level of feed-in mechanism 21 is higher than the horizontal level of connecting gear 22, and the horizontal level that feeds out mechanism 23 is higher than the horizontal level of connecting gear 22.In addition, move in order to make file D can press close to the plane of scanning motion 111 that scanning platform 11 is arranged in scanning area 32, the position of connecting gear 22 is lowered, and therefore, the roller 221 of connecting gear 22 is set in the storage tank 12 of console module 10.
For feed documents D more successfully, paper carrier 20 can further comprise second connecting gear 24, and it is positioned at the upstream of connecting gear 22, in order to being sent to connecting gear 22 from the file D of feed-in mechanism 21.Just, second connecting gear 24 is between feed-in mechanism 21 and connecting gear 22.Second connecting gear 24 includes roller 241 and 242.
When scan module 40 comprises light source 42 and contact-type image sensor 41, in order to guarantee more effectively that file D can more press close to the plane of scanning motion 111 at scanning position SP, paper carrier 20 can further comprise pressing assembly 25, it is arranged at the downstream of scanning area 32, in order to the file D by scanning area 32 is exerted pressure, make file D smooth the plane of scanning motion 111.In the case, console module 10 can further comprise section 13, and it is positioned at the downstream of scanning area 32, and relative with pressing assembly 25.Section 13 is in abutting connection with the plane of scanning motion 111, and has low spot LP, and low spot LP is lower than the plane of scanning motion 111.Because low spot LP is lower than the plane of scanning motion 111, pressing assembly 25 can be depressed into the position lower than the plane of scanning motion 111 with file D at this section 13, and thus, the file that is arranged in scanning area 32 just can the smooth plane of scanning motion 111.
Therefore, file D is fed in paper-feeding channel 30 and passes through connecting gear 22, scanning area 32, pressing assembly 25 in regular turn to feeding out mechanism 23.
For file D can be presented smoothly at paper-feeding channel 30, scanning device 1 can further comprise arrangement for guiding 50 and inclined-plane 112.Arrangement for guiding 50 is arranged in paper-feeding channel 30, and is positioned at the downstream of scanning area 32, in order to leader files D to feeding out mechanism's 23 paper deliveries.Inclined-plane 112 is in abutting connection with the plane of scanning motion 111, can be along the inclined-plane 112 moves to the plane of scanning motion 111 so that be transmitted file D that mechanism 22 feeds out.Inclined-plane 112 can be the slope that forms of scanning platform 11 front ends or by the formed inclined-plane of the two side walls of paper-feeding channel 30.
In the case, file D is fed in paper-feeding channel 30 and passes through connecting gear 22, scanning area 32, arrangement for guiding 50 in regular turn to feeding out mechanism 23.
For scan module 40 can be proofreaied and correct by operative norm, paper carrier 20 can further comprise background colour table 26, and is relative with the plane of scanning motion 111.Scan module 40 can be moved with a plurality of lines on the scanning background colour table 26 to carry out the correction of standard white (deceiving) or color.Certainly, paper carrier 20 can also further comprise pressing assembly 25 ', relative with the plane of scanning motion 111, in order to the file D by scanning area 32 is exerted pressure, make file D smooth the plane of scanning motion 111.
Fig. 2 shows the schematic diagram according to the file scanning device of second embodiment of the invention.As shown in Figure 2, the scanning device 1 of present embodiment is similar to first embodiment, difference be the scan module 40 of scanning device 1 ' comprise Charged Coupled Device image sensor 41 ', light source 42, speculum 43 and lens 44.
Pass through the above embodiment of the present invention, two rollers of connecting gear 22 can be kept with the plane of scanning motion in order to the cramping point of clamping file and be positioned on the same horizontal plane, add the pressing assembly of the rear end that is arranged at the plane of scanning motion, make original copy can be smooth scanning plane ground by scanning area, and do not have the influence that image that known technology produces impacts.In addition, though in Fig. 1, the top of the plane of scanning motion 111 be provided with another pressing assembly 25 ', the pressing assembly 25 of the plane of scanning motion 111 tops ' can be omitted.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present invention, but not with narrow sense of the present invention be limited to the foregoing description, in the situation that does not exceed spirit of the present invention and following claim, the many variations of being done is implemented, and all belongs to scope of the present invention.
