Embodiment Construction

[0021] figure 1 It is an automatic paper feeding device with real-time paper jam detection function according to the embodiment of the present invention. see figure 1 , the automatic paper feeding device 1 of the embodiment of the present invention is placed on a flatbed scanner 34, and the flatbed scanner 34 has an optical machine 36 inside for scanning documents. In fact, the automatic paper feeding device 1 can be combined with a fixed optical machine to form a paper-fed scanner.

[0022] The automatic paper feeding device 1 includes a housing 10 , a motor 12 mounted on the housing 10 , speed detectors 26 , 28 , 30 and a control circuit 32 . The first driving roller 14 is driven by the motor 12 to rotate, thereby driving the first driven roller 16 to rotate. The second driving roller 18 is driven by the motor 12 to rotate, thereby driving the second driven roller 20 to rotate. Similarly, the third driving roller 22 is driven by the motor 12 to rotate, thereby driving th...

Abstract

The automatic paper feeder with real-time paper jamming detecting function includes casing, motor mounted on the casing, driving roller driven by the motor to rotate, driven roller rotated by the driving roller, rotation speed detector for detecting the rotation speed of the driven roller and outputting the rotation speed signal, and control circuit. The cooperation between the driving roller and the driven roller conveys paper in between, and the control circuit receives the rotation speed signal to judge whether to exist paper jamming based on the signal.

Description

technical field [0001] The present invention relates to an automatic paper-feeding device, in particular to an automatic paper-feeding device with the function of detecting paper jams in real time. Background technique [0002] In recent years, scanning devices have become one of the commonly used products in offices and individuals. Through the scanning device, the document can be digitized, and it can also cooperate with a printer to realize the function of photocopying. [0003] As the number of documents to be scanned increases, traditional flatbed scanners are no longer used. Therefore, the use of a sheet-fed scanner or a flatbed scanner with an automatic sheet feeder is a product currently under development. [0004] Occasional paper jams occur when the automatic document feeder is feeding documents. The traditional technology for detecting paper jams in the automatic paper feeder is mostly based on the fact that the paper is squeezed...
