Abstract:
Automatic sheet feeding apparatus/recording apparatus include a feed roller 11 for feeding sheets out of a stack holding unit, a separation roller 12, in contact with the feed roller 11, for separating the sheets one by one; a return lever 13 for pushing back sheets to the stack holding unit and aligning them; and flanges 14 integrally turning with the feed roller; wherein the feed roller 11 and the return lever 13 do not overlap with each other but the flanges 14 and the return lever 13 do overlap in a side view during one turn of the feed roller 11. With the configuration, the apparatus can utilize the sheet conveying face of the feed roller longer and more effectively, and to eliminate the rush-in phenomenon, namely letting the tips of sheets enter deep into the feeding apparatus inadvertently at the time of setting the sheets into the sheet stack holding unit.
