Claims

[Claims for Utility Model Registration] Paper storage units removably arranged in multiple stages on a frame body of a multi-stage paper feeding device can be inserted into the paper feeding stages after one or more stages have been removed, and the frame main body comprises: A tray stand that can be inserted and removed along a guide rail attached to the tray, a paper feed separation unit rotatably attached to the tray stand, and a paper feed separation unit that is mounted on the upper part of the tray stand so as to be movable along the paper feeding direction. a paper stock unit, which is normally located close to the paper feed separation unit, and is moved in a direction away from the paper feed separation unit by a biasing means when the tray base is pulled out from the frame main body; A front plate is attached to the paper stock unit to regulate the position of the leading end of the paper to be loaded on the paper feed side, and a front plate is provided thereon in correspondence with the pick up roller of the paper feed separation unit. When the tray base is pulled out, the paper stock unit is moved by the urging means, and the paper feed separation unit, which is partially in contact with the paper stock unit, rotates, and the pick up roller is rotated. A paper feeding device characterized in that the paper feeding device is retracted into the notch.
