Claims

[Scope of claim for utility model registration] A pair of left and right paper stacking plates arranged to be slidable in the width direction of the paper, and paper guides formed upright on both sides of the paper stacking plates to regulate the width direction of the paper. a paper feed roller rotatably attached to a shaft passed between the paper guides; an elastic member that urges the paper stacking plate upward to press the paper against the paper feed roller; An automatic paper feeder comprising a separation claw for separating paper, and separating and feeding the paper stacked on the paper stacking plate one by one by rotating the paper feed roller, comprising: a thin elastic member; The upper part is divided in a direction parallel to the paper feeding direction, and the divided part is bent forward from the base in the paper feeding direction so that the end is upward, and this inclination angle is aligned with the paper surface. The bent portion located at an angle of 30° or less and on the front side in the feeding direction is defined as a first separating portion.
A separating member is formed in which a second separating part is a bent part located further forward than the separating part and having an inclination angle equal to or greater than the inclination angle of the first separating part, and each separating part of this separating member The automatic apparatus is characterized in that friction members each having a friction coefficient capable of separating the paper sheets are fixed to the upper surface to serve as separation claws, and each friction member of the separation claws independently presses against the paper feed roller. Paper feed device.
