ABSTRACT:
A paper feed has a door and a paper carrying tray, and raises the tray as paper is fed. A first detector that detects the presence of paper is located below a paper feed position by a margin corresponding to a given number of paper sheets, and second detector that detects the presence of paper is located below the first detector. If an open state of the door is detected, the paper carrying tray is lowered to a position where the second detector ceases to detect the presence of paper. If the first and second detectors detect the presence of paper after the tray is lowered, the tray is lowered to the position where the second detector ceases to detect the presence of paper. If a closed state of the door is detected after the tray is lowered, the tray is raised so that the uppermost one of paper sheets on the tray is situated in the paper feed position.
