Abstract:
1. A sheet feed apparatus comprising: a sheet feed tray on which a plurality of sheets is loaded; a sheet feed roller which is provided at a forward position of the sheet feed tray in a sheet feed direction, and which feeds the loaded sheets to a conveying path; a lift detection sensor which detects a lift of a bound sheet bundle which occurs when at least a top sheet of the bound sheet bundle is fed by the sheet feed roller or when one or more sheets are lifted from the sheet feed tray by a user; and a control unit which controls a start and stop of sheet feeding of the sheets loaded in the sheet feed tray, wherein the control unit stops the sheet feeding if the lift detection sensor detects the lift during a period after starting the sheet feeding, and does not stop the sheet feeding if the lift is detected after the period.
