Abstract
A paper feeding mechanism holds a stack of print paper in pressure contact with a paper pick-up roller. The paper pick-up roller feeds the print paper out of the tray one page at a time when the paper pick-up roller is rotated. The paper feeding mechanism has first and second supporting surfaces. The first supporting surface holds the stack of print paper from behind a back surface of the print paper. The first supporting surface is at a second angle .theta. 2 with the horizontal direction such that the print paper slides along the first supporting surface to the second supporting surface with the aid of the gravity of the print paper. The second supporting surface supports the stack of print paper thereon. The second supporting surface is inclined at a first angle .theta. 1 with a horizontal direction such that a leading edge of each page of the print paper abuts the second supporting surface and slides toward the rotating paper pick-up roller with the aid of a gravity of the print paper.
