Problems solved by technology

However, the light source 121 of the existing double-sided scanning module 1 is too far away from the first scanning area 114, so that the light beam generated by the light source 121 cannot actually be projected onto the document, and scanning cannot be performed.
If the existing double-sided scanning device 1 uses a light source with high intensity, it may be possible to project its beam onto the document, but its scanning quality is quite limited.

Abstract

The invention relates to a double-sided scanning device, which comprises an automatic paper feeder and a platform type scanner, wherein the automatic paper feeder comprises a feeder shell, a scanning glass sheet and a first light source; and the platform type scanner comprises a scanner shell, a glass platform, a second light source and a scanning module. In the double-sided scanning device, as the scanning glass sheet and the first light source are arranged in the automatic paper feeder and scanning is performed in the automatic paper feeder, the two sides of a file can be scanned by feedingthe file once and the quality of the scanning in the automatic paper feeder can be improved; and thus, the drawbacks of the conventional double-sided scanning device are overcome.

Description

technical field [0001] The invention relates to a scanning device, in particular to a double-sided scanning device capable of scanning documents on both sides. Background technique [0002] The main function of the scanning device is to collect images to convert the content of paper documents into electronic documents by scanning, so that users can disseminate, organize or save them. With the maturity of scanning device technology, scanning devices are becoming more and more popular. [0003] The earliest scanning devices can only scan images on one side of a document. When users want to scan images on both sides of a document, they must manually turn over the document so that the scanning device can scan images on the other side of the document. In view of the fact that manual flipping is too troublesome, a sheet-fed scanning device that does not need to be manually flipped has been developed on the market, so that users only need to place a stack of documents on the paper...
