ABSTRACT:
A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes. When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.
