ABSTRACT:
A sheet feeding apparatus including a feeder for feeding sheets stacked up in a sheet stock unit, a leading end regulator for regulating the leading ends in a feeding direction of sheets stacked up in the sheet stock unit, and a driver for moving the leading and regulating member. The feeder unit is free to contact with or depart from the sheets, the leading end regulator is movable in a sheet feeding route between a regulating position for regulating the leading ends of sheets, and a retreat position for releasing the leading end of the sheets from regulation by moving away from the sheet feeding route, and the leading end regulator contacts with and supports the lower end of the feeding unit holding the feeding unit at a position apart from the sheets when the leading end and regulator is at the regulating position, and brings the feeding unit into contact with the sheets releasing the support to the feeder without contacting with the lower end thereof when the leading end regulator is at the retreat position.
