Paper feeding device for image processing equipment and image processing equipment

Abstract

The invention provides a paper feeding device for image processing equipment and the image processing equipment. The paper feeding device comprises a paper feeding box, a pick-up roller, a pick-up shaft, a paper supporting plate, guide grooves and a guide shaft, wherein the pick-up shaft penetrates through the pick-up roller, and the two ends of the pick-up shaft are arranged on a front frame anda rear frame of the paper feeding box correspondingly; the paper supporting plate is arranged on the paper feeding box and located at the bottom of the pick-up roller; the guide grooves are formed inthe front frame and the rear frame correspondingly in the height direction of the paper feeding box; and the guide shaft is pivoted to the end, close to the pick-up shaft, of the paper supporting plate, the axis of the guide shaft is parallel to the pick-up shaft, the two ends of the guide shaft are arranged in the two guide grooves correspondingly and slide up and down in the height direction ofthe paper feeding box, and the paper supporting plate swings up and down with the guide shaft as a fulcrum so that the front end of to-be-conveyed paper on the paper supporting plate can be located atthe engagement part of the pick-up roller. When different numbers of paper are placed in the paper feeding box, the paper feeding device prevents the contact positions between the pick-up roller andthe front end of the paper from being changed, and the paper sticking rate of the image processing equipment is decreased.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a paper feeding device for image processing equipment and the image processing equipment. Background technique [0002] At present, the cartons of image processing equipment such as copiers, especially in FRPD (Friction Retard PadFeeder (feeding device using buffer pad), generally include Nudge Roller (NR, nudge roller) for conveying copy paper, pick-up roller (FR), In a carton with a Retard Pad (RPAD, buffer pad) that is pressed on the pickup roller and a spring that presses the buffer pad on the pickup roller), the position of the front end of the paper will change when the number of papers placed in the carton changes from more to less. . At this time, the pick-up roller may not be in contact with the paper, so the pick-up roller cannot play the role of picking up the paper. In particular, the position of the front end of the paper placed in the large-capacity paper box wil...
