ABSTRACT:
A sheet feeder apparatus is controlled for sequentially feeding sheets to a predetermined processing position. A detection signal of a sheet stacked in a rise and lower tray located at a lower limit position is received before receiving a feed signal to start feeding of the sheet. Upon receiving the feed signal to start feeding of the sheet, the rise and lower tray is moved from the lower limit position to an upper limit position, and the sheet is supplied.
