A stopper member regulates the leading edges of sheets stacked on a sheet supply tray. In a first position of the stopper member, the sheets on a sheet supply tray are prevented from advancing into a paper feed path, and in a second position, the sheets drawn out by a draw-out device pass. The stopper member can be moved to a third position between the first and second positions. The displacement to the third position from the first position is associated with the lowering of the draw-out device for drawing out the sheets from the sheet supply tray, and the displacement from the third position to the second position is accomplished by the leading edge of a sheet drawn out by the draw-out device. This structure prevents damage to the original stacked on the sheet supply tray, and attains a simple structure and a low cost apparatus.
