)項記載の給紙装置。[Claims for Utility Model Registration] (1) A device that feeds paper such as a form by pressing it against the paper and rotating it, comprising a take-out roller, a multi-feed preventer, and a conveyance roller; The outer periphery of the take-out roller and the paper feed roller is formed of a high-friction surface and a low-friction surface, and the distance from the center of the take-out roller to the center of the paper feed roller is x, the smallest sheet that can be fed. Let L be the length of the high friction surface on the outer periphery of the take-out roller, and let β be the length of the high friction surface on the outer periphery of the take-out roller. The high-friction surface of the paper feed roller comes into contact with the high-friction surface of the take-out roller before the high-friction surface of the take-out roller, and the high-friction surface of the take-out roller comes into contact with the surface of the paper before the trailing edge of the paper leaves the outer periphery of the take-out roller. A paper feeding device comprising the take-out roller and the paper feeding roller having a relationship such that L-x>β so that they separate. (2) After feeding the paper by rotating the take-out roller and the paper feed roller at low speed, and detecting the paper with a paper detection means provided between the paper feed roller and the transport roller, Utility model registration claim No. 1, characterized in that the paper feed roller is rotated at high speed to feed the paper.
Paper feeding device described in ).
