Paper pressing device

Abstract

The invention relates to a paper pressing device which comprises a front cover and a rear cover which can be mutually fastened with the front cover, wherein the front cover comprises an inner wall and can be rotatably opened or fastened relative to the rear cover. The paper pressing device further comprises a press fit component which is fixedly arranged on the inner wall of the front cover, and the press fit component comprises a pressing and holding piece and at least one roller, wherein the pressing and holding piece comprises a fixing end and an elastic supporting arm which is connected to one side of the fixing end and is elastically bent relative to the fixing end; the elastic supporting arm is provided with at least one set of fixing sheets, and each set of the fixing sheets are provided with a set of corresponding shaft holes; and the rollers penetrates in the shaft holes of the fixing sheets and can roll relative to the shaft holes. The rollers of the paper pressing device and paper have rolling friction, and a contact area between the rollers and the paper is small, thus the frictions of the rollers and the paper can be reduced so as to reduce paper jam phenomena.

Description

technical field [0001] The invention relates to a paper pressing device. Background technique [0002] Printing devices such as copiers, fax machines, printers, scanners or Multi Function Printers (MFPs), as high-efficiency office equipment, are increasingly being used widely. Existing copier generally comprises a printing unit and a paper pressing device 10 (as figure 1 shown). The paper pressing device 10 is used for storing paper, and the printing unit is used for printing the paper stored in the paper pressing device 10 . The paper pressing device 10 includes a front cover 11 , a paper pressing fixing piece 12 , an elastic member 13 disposed between the front cover 11 and the paper pressing fixing piece 12 , and a rear cover 14 for installing paper. One end of the paper holding plate 12 is fixed on the inner wall 112 of the front cover 11 , and the other end is connected to the elastic member 13 . When in use, the paper is placed in the rear cover 14 , and the front ...

AI Technical Summary

Problems solved by technology

[0003] However, the paper platen 10 uses the elastic member 13 to cooperate with the paper platen 12 to repeatedly move the paper, and the contact area between the paper and the paper platen 12 is large. Therefore, the paper platen 10 sends paper to the printer. When unit printing, the friction between the paper and the paper platen 12 is also relatively large, and paper jams are prone to occur, which brings inconvenience to users
