摘要: A sheet feeding roller is brought into contact with an uppermost sheet stacked on a hopper, and rotates to feed the uppermost sheet to the recording apparatus. A separation pad presses the uppermost sheet against the feeding roller so that the upper most sheet is separated from a next uppermost sheet. A first sheet returner pushes back a first part of the next uppermost sheet situated on the separation pad to the hopper. A second sheet returner pushes back a second part of the next uppermost sheet situated on the separation pad to the hopper. The sheet feeding roller, the separation pad and the first sheet returner are incorporated in a single unit which is disposed at a first position of a sheet feeding passage formed on the hopper. The second sheet returner is solely disposed at a second position of the sheet feeding passage.
