Abstract
An apparatus for sequentially feeding an accumulation of sheets stored in a storing section thereof one by one to a predetermined transport path. A pressing member presses the accumulation of sheets to one side in a direction in which the sheets are accumulated. A pair of pick-up rollers abut against the surface of the accumulation of sheets at the above-mentioned one side. A pair of feed rollers are located at a predetermined feed position in parallel with the pair of pick-up rollers. Actuators cause the pick-up roller pair and the feed roller pair to move toward and away from each other in a reciprocating motion. A pair of reverse rollers are located to face the pair of feed rollers and rotatable in a counter-feed direction opposite to a predetermined feed direction. The pick-up rollers and feed rollers moving toward and away from each other pay out a sheet from one side of the accumulation. The reverse rollers are rotated in the counter-feed direction to separate a sheet being entrained by the sheet being paid out in close contact with it and return said the entrained sheet to the storing section. Opposite side edges of the sheet being paid out by the pick-up rollers and feed ro…
