Abstract
Automatic sheet feeding apparatus/recording apparatus include a feed rollerfor feeding sheets out of a stack holding unit, a separation roller, in contact with the feed roller, for separating the sheets one by one; a return leverfor pushing back sheets to the stack holding unit and aligning them; and flangesintegrally turning with the feed roller; wherein the feed rollerand the return leverdo not overlap with each other but the flangesand the return leverdo overlap in a side view during one turn of the feed roller 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.
