Abstract

The invention provides a paper supply device, an automatic paper transferring device and an image formation device. By adoption of the paper supply device, the automatic paper transferring device andthe image formation device, when a large quantity of paper is supplied, and deformation of the paper can be reduced during paper transferring to make sure that different types of paper can be smoothlytransferred to a clamping part of a separation roller. The paper supply device (1) is provided with a paper fetching roller (2), a paper supply roller pair (5) and a movable guide block (D), whereinthe paper fetching roller (2) fetches paper from a paper stack (T) and transfers the paper to the paper supply roller pair (5); the paper supply roller pair (D) is used for supplying the paper transferred from the paper fetching roller (2) to the image formation device piece by piece; and the movable guide block (D) is located between the paper fetching roller (2) and the paper supply roller pair(5) and is used for supporting the paper from the lower side of the paper when the paper is transferred, and the position of the movable guide block (D) can be changed according to the height of the paper stack (T). The paper supply device (1) is further provided with an auxiliary mechanism (S). The auxiliary mechanism is located between the paper fetching roller (2) and the paper supply roller pair (5) and is used for assisting in paper transferring from the upper side of the paper when the paper is transferred.

Description

technical field

[0001] The present invention relates to a paper feeding device, and more particularly to a paper feeding device corresponding to large-capacity paper feeding, an automatic paper conveying device and an image forming apparatus provided with the paper feeding device. Background technique

[0002] For a general paper feeding device, when corresponding to a stack of paper, the paper feeding and feeding can be performed by lowering the paper pick-up roller. However, in this paper feeding device, as the number of paper sheets in the paper stack increases, the gap between the front end of the uppermost paper in the paper stack and the pair of paper feed rollers increases. , because there is no guide rail between the rollers, and the space is large, the paper is easily bent and deformed due to the weight of the paper during the conveyance process after the paper is picked up by the pick-up roller and transported to the paper-feed roller pair, and the paper may be sep...
