Abstract

The present invention relates to a paper feeding device with a paper holding / releasing structure. The paper feeding device comprises a case, a paper feeding channel, a paper taking module, a driving shaft and a paper holding / releasing structure; wherein the paper holding / releasing structure comprises a control lever with a projecting part and a pedestal having a first spacing groove and a second spacing groove. When the projecting part is positioned at the first spacing groove, the paper holding / releasing structure is in a holding paper state; and when the projecting part is positioned at thesecond spacing groove, the paper holding / releasing structure is in a releasing state. The present invention achieves the advantages of stable motion and convenient control, and is convenient for users to deal with the paper jam.

Description

technical field [0001] The invention relates to a paper feeding device, in particular to an automatic paper feeding device with a paper jam release structure. Background technique [0002] Since the automatic paper feeding technology is becoming more and more sophisticated nowadays, it has been widely used in printers, copiers and business machines. The main purpose is to automatically feed most documents into these machines to save manpower consumption. [0003] see figure 1 , which is a structural schematic diagram of an existing automatic paper feeding device. The automatic paper feeding device 1 includes a paper picking roller 10 , a paper separation roller 11 , a paper separation piece 12 and a paper feeding channel 13 , wherein the paper separation roller 11 runs with the rotation of the drive shaft 14 . When the automatic document feeder 1 starts to feed paper, the pick-up roller 10 feeds the document 15 from the document inlet 16 to the paper separation roller 11, ...
