Embodiment Construction

[0033] As described in the prior art above, the present invention proposes a double-sided scanning device that can improve the defects of the existing double-sided scanning device.

[0034] see figure 2 , which is a schematic structural diagram of a preferred embodiment of the double-sided scanning device of the present invention. figure 2 Among them, the duplex scanning device 200 includes a flatbed scanner 201 and an automatic document feeder 202 , and the automatic document feeder 202 is disposed on the flatbed scanner 201 . The flatbed scanner 201 includes a scanning module 203 for reading the image of the document 212 in the scanning area 215, and the scanning module 203 is arranged in the flatbed scanner 201; the automatic document feeder 202 includes an input tray 204, an output tray 205, the first paper feeding channel 206, the paper fetching roller 207, the friction baffle 208, the paper feeding roller group 209, the turning area 210, the second paper feeding chann...

Abstract

The invention relates to a two-sided scanning device. A paper fetching roller is arranged on a paper feeding tray, and the two-sided scanning device starts scanning from the files nethermost a stack of files. The second-scanning type two-sided scanning device can achieve the effect that the sequence of the scanned files is the same as the sequence of the currently scanned files by performing scanning from the files nethermost the stack of the files. The two-sided scanning device can finish the two-sided scanning to achieve the effect that the sequence is the same as the original sequence only by passing through the scanning area twice, and compared with the prior third-scanning two-sided scanning device, the times of the files to pass through the scanning area during the feeding process is reduced by one time, therefore, the scanning time of the prior two-sided scanning device is obviously reduced; and in addition, compared with the single-sweep two-sided scanning device with two groups of scanning modules, the invention also saves the cost of a group of scanning modules.

Description

technical field [0001] The invention relates to a scanning device, in particular to a double-sided scanning device capable of secondary scanning. Background technique [0002] The main function of the scanner is to capture images to convert the content of paper documents into electronic documents by scanning, so that users can disseminate, organize or save them. As scanner technology matures, scanners are becoming more and more popular. [0003] The earliest scanners can only scan images on one side of a document. If you want to scan images on both sides of a document, you must manually turn the document over so that the scanner can scan the image on the other side of the document. In view of the fact that it is too troublesome to turn over manually, a double-sided scanning device has appeared. [0004] A general double-sided scanning device includes a flatbed scanner and an automatic document feeder arranged on the flatbed scanner, wherein the automatic document feeder is...
