Problems solved by technology

[0005] The correction part 3 in the above-mentioned double-sided printing paper conveying unit is fixedly installed on the guide part 1, and it cannot be corrected for different sizes of paper during double-sided printing.
Even when the user uses this paper conveying unit to convey and correct paper of different sizes, the probability of paper jams in the image forming device is very high due to the mismatch between the paper size and the position of the correction piece, or the image layout on the printed paper There is a difference from the expected layout

Abstract

The invention relates to a double-sided printing paper conveying unit. The double-sided printing paper conveying unit comprises a paper feeding device for conveying paper in the conveying direction, a guide part for guiding the paper conveyed by the paper feeding device, and a correcting part, wherein the correcting part is used for correcting the oblique posture of the paper in the conveying process in the correcting direction perpendicular to the conveying direction and is movably installed on the guide part. The double-sided printing paper conveying unit further comprises a moving mechanism, the moving mechanism is installed on the guide part and can move the correcting part between a first position and a second position in the correcting direction, and thus the correcting part can correct paper in different sizes. Meanwhile, the invention relates to an image forming device with the double-sided printing paper conveying unit.

Description

technical field [0001] The present invention relates to an electrophotographic image forming apparatus for forming an image on paper, in particular to a paper conveying device used in the image forming apparatus; more particularly, the present invention relates to an image forming apparatus for double-sided printing A unit used to transport and correct paper during paper transport. Background technique [0002] The existing double-sided printing image forming device mainly includes a frame, an image forming unit installed in the frame, and a paper conveying mechanism, wherein the paper conveying mechanism includes a paper picking device, a paper conveying device, a paper discharging device, and a double-sided printing paper conveying mechanism. unit. When the image forming device is working, the paper in the paper tray is picked up by the paper pick-up device, and is conveyed by the paper conveying mechanism through the transfer unit and the fixing unit to the paper dischar...
