Description
Technical field
The present invention relates to a kind of double-faced scanning device, especially relate to a kind of double-faced scanning device with two groups of scan modules.
Background technology
The major function of scanner is to carry out image capture, converts the content of the Hard copy file mode by scanning to the electronics shelves, propagates, puts in order or preserve to make things convenient for the user.Along with the maturation of scanner technology, scanner is universalness more and more also, and the development of scanner is also innovated in research and development constantly at aspects such as sweep speed and scanner volumes except increasing resolution and improving the quality of scanning.
Scanner the earliest only can the scanning document single face image, if the two-sided image of scanning document, then must with manual mode with the file turn-over so that scanner can the scanning document another side image.
In recent years because market day by day improves for the demand of duplex scanning, but so the personage of this area also be devoted to provide the double-faced scanning device of the two-sided image of scanning document.
General on the market double-faced scanning device has two kinds, and first kind is the double-faced scanning device with one group of scan module.Owing to have only one group of scan module, therefore, just can realize the purpose of duplex scanning if desiring the two sides of scanning document then must overturn file by specific mechanism design.In the scanning process of this kind double-faced scanning device, file need be transferred usually by scanning area twice (being called two-pass) or three times (being called three-pass) just can finish duplex scanning one time.The inconvenience of this kind double-faced scanning device is that the activity duration is oversize.
Another kind of double-faced scanning device is the scanning means with two groups of scan modules.The both sides that these two groups of scan modules lay respectively at the file in the scanning area are reading the image on file two sides, so file need only be transferred the operation that once can finish duplex scanning by scanning area.With first kind of double-faced scanning device by comparison, second kind of double-faced scanning device relatively saved time.
See also Fig. 1, it is aforementioned known schematic diagram with double-faced scanning device of two groups of scan modules.Double-faced scanning device 100 among Fig. 1 comprises automatic paper feeder 101, glass platform 102, feeding box 103, paper output box 104, first scan module 107, second scan module 108, paper-feed group 109, paper delivery roller set 110, the first paper feed roller wheels 105, the second paper feed roller wheels 106 and path of travel 111.Wherein first scan module 107 is set in the automatic paper conveying apparatus 101, and second scan module 108 is arranged at glass platform 102 belows of scanner.When double-faced scanning device 100 begins to scan, the file 120 that is positioned on the feeding box 103 is delivered in the path of travel 111 by paper-feed group 109, make file 120 by the scanning window 130 on the glass platform 102 by the first paper feed roller wheels 105 again, allow first scan module 107 and second scan module 108 can pass through the image of scanning window 130 scanning documents 120, wherein first scan module 107 is in order to first of scanning document 120, and second scan module 108 is then in order to second of scanning document 120.After file 120 is fully by scanning window 130, represent that its two-sided image all is scanned.The second paper feed roller wheels 106 and go out 110 of paper rollers in order to file 120 is sent to paper output box 104.
Because first scan module 107 and second scan module 108 are via scanning with one scan window 130, for interacting, the light source of avoiding two groups of scan modules causes image fog, though therefore second scan module 108 is the tops that are positioned at first scan module 107, but can not aim at first scan module 107, and a little skew must will be arranged, the light source of the two can not interacted.As shown in Figure 1, when file 120 is transported to scanning window 130 on the glass platform 102, but file 120 can be introduced in the sweep limits of first scan module 107, and with first of scanning document 120, this moment, second scan module 108 did not come into operation as yet by first scan module 107 running earlier.When but file 120 is begun to enter in the sweep limits of second scan module 108 after the paper delivery direction moves a bit of distance, second of scan module 108 beginning this moment second scanning documents 120, first scan module 107 is still first of scanning document 120 simultaneously.
The well known device of Fig. 1 has following defective: at first, because first scan module 107 and the second accurately contraposition of scan module 108 cause the increase in man-hour in the production and assembly.Moreover in well known device shown in Figure 1, because second scan module 108 is to scan via scanning window 130, therefore second scan module 108 and relevant document conveying arrangement also all must be set at the position of corresponding scanning window 130.This makes automatic paper conveying apparatus 101 must have sizable height and second scan module 108 could be contained in wherein.Therefore the shared space of double-faced scanning device also relatively becomes big.
