Abstract
A paper feeding apparatus is provided with a paper feed roller supported rotatably by an image forming system body via a roller shaft, a paper feeding table which can be drawn freely in the axial direction of the roller shaft from a paper feed opening of the image forming machine body, a paper feeding hopper guided and supported by the paper feeding table so as to be movable freely to and from the paper feed roller horizontally, and in a direction orthogonal to the axial direction of the roller shaft, and an interlocking device which moves the paper feeding hopper freely to and from the paper feed roller in an interlocking motion with the drawing and restoring operation of the paper feeding table. Thereby, when the paper feeding table moves backward from the front, the paper feeding hopper is moved to the side of the paper feed roller along guide rails by the interlocking device. Then, the paper feed roller is rotated and the paper feeding hopper is received in a predetermined position without slacking of the paper.
