Description

technical field [0001] The invention relates to an automatic paper feeder, in particular to an automatic paper feeder provided with a paper blocking module. Background technique [0002] With the evolution of the times, technology is developing day by day. With the development of technology, the preservation of documents has evolved from traditional paper document filing to electronic document storage. The tool generally used for document electronic work is a scanning device. Scanning The device is used to convert the content of paper documents into electronic documents by scanning, so that users can spread, organize or save them. [0003] Early 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, an automatic document feede...

AI Technical Summary

Problems solved by technology

[0007] Although the existing automatic document feeder 1 can prevent the document D from entering the automatic document feeder 1 when it is not activated, there are two disadvantages in the existing automatic document feeder 1: first, because the paper blocking sheet 1132 moves vertically Therefore, the upper cover 10 of the automatic document feeder 1 must have a certain height so that the paper stopper 1132 can move vertically in the upper cover 10, so that it will be difficult to realize the thinning of the automatic document feeder

Second, since the paper stopper 1132 moves vertically up and down, when the document D passes and the paper stopper 1132 falls and touches the document D, the paper stopper 1132 may cause damage to the document D, and even form a A perforation, and while the paper stop 1132 passes through the document D, the feeding of the document D is still in progress, which will make the damage of the document D more serious
