ABSTRACT:
In separating one of a plurality of sheets stacked in a cassette from the remainder, a separation pad holder facing one side of the circumference of a sheet feed roller, which is rotatably driven, is urged in such a manner that a separation pad is brought into contact with or separation from the circumference of the sheet feed roller. Accordingly, an uppermost sheet can be pushed out in separation by friction force. When the sheet reaches a pair of sheet feed rollers, the separation pad holder can retreat with the interference of a projection formed in the separation pad holder by its own tension of the sheet across each circumference of the sheet feed collars and the pair of sheet feed rollers, thus eliminating friction generated between the separation pad and the sheet.
