Claims

[Scope of Claim for Utility Model Registration] A movable stacking member for stacking paper, and a paper feed roll that presses a part of its circumferential surface against the front end in the feeding direction of the stacked papers on the movable stacking member, and a paper feed means for feeding paper; a paper advance regulating member that is brought close to or in pressure contact with the peripheral surface of the paper feed roll and prevents the paper taken out together with the uppermost paper from advancing to prevent double feeding; and the movable stack. an operating member that engages with the movable stacking member and moves the movable stacking member between a paper feeding position where the stacked paper is brought into pressure contact with the peripheral surface of the paper feed roll and a non-paper feeding position where the pressure contact is released; rotating the paper feed roll in a direction opposite to the paper feeding direction in conjunction with an operation of moving the movable stacking member from the paper feeding position to the non-paper feeding position by the operating member interposed between the paper feeding means; and a paper return mechanism for returning the paper taken out from the movable stacking member in the paper feeding direction.
