Abstract
A sheet-feeding apparatus with a paper stopper includes a sheet-feeding base having a sheet-placing stand for placing sheets, a roller shell located on the sheet-feeding base having two side walls, a preliminary feeding roller unit and a feeding roller unit contained in the roller shell, a stopper member rotationally attached to the side wall of the roller shell and a follower member rotationally attached to the feeding roller unit and located at the downstream side of the stopper. Before starting a feeding operation, the stopper member is pushed by a sheet in the sheet-feeding base to move forward and presses on the follower member. The follower member would not move any further because the follower member is restricted by an upright wall of the sheet-feeding base.
