Further, if the paper separation sheet 18 cannot be accurately assembled on the paper separation roller 16, that is, the direction of the rear edge of the paper separation part 18a of the aforementioned paper separation sheet 18 (ie, the left edge of the paper separation part 18a in the figure) There is a deviation from the axial direction of the separation roller 16
Since the front edge of the paper S is first trimmed to the rear edge of the aforementioned paper separation part 18a dur

Embodiment Construction

[0021] Please refer to FIG. 2 , which is a schematic cross-sectional view of a preferred embodiment of the automatic document feeder (Automatic Document Feeder, ADF) 20 of the present invention. As shown in the figure, the automatic document feeder 20 has a paper input box 30 , a paper feeding mechanism 40 , a relay roller set 50 and a paper output roller set 70 . Wherein, the paper tray 30 is used for carrying papers (not shown). The paper feeding mechanism 40 is used to drive the papers in the paper tray 30 to be fed into the automatic paper feeder 20 one by one. The relay roller set 50 is located at the downstream of the paper feeding mechanism 40 and is used to transport the paper leaving the paper feeding mechanism 40 to a reading and writing position 60 for scanning, photocopying and other operations. The paper output roller set 70 is located downstream of the relay roller set 50 , and is used to drive the paper away from the reading and writing position 60 and send the...

Abstract

A paper feeding mechanism able to prevent the skew of fed paper is composed of a paper advancing roller, a paper separating roller at the downstream of paper advancing roller, a paper separating plate close to said paper separating roller and with an arc paper-separating part, a pressure regulating unit with a pressure-applying spherical part, and a pressing plate of paper-separating plate with a recess on its back for matching with said pressure-applying spherical part.

Description

technical field [0001] The invention relates to a paper feeding mechanism, in particular to a paper feeding mechanism capable of preventing skewed paper feeding. Background technique [0002] For early computer users, scanners were rare peripherals. Early scanners were usually used in professional digital image processing work due to their high price and difficult operation. However, with the development of digital imaging technology, many cheap and easy-to-use scanners have flooded into the market. In the past few years, they have become an indispensable part of personal or small office computer systems. [0003] Generally, common scanners can be divided into two mainstreams: flatbed and sheet-fed. Among them, flatbed is the most popular scanner type in SOHO. A flatbed scanner is designed like a small copier, where paper, books or other items to be scanned are placed on a flat glass for scanning. Moreover, with the development of scanning technology, not only two-dimens...
