Abstract
The invention provides a sheet feeding device in which a lifter member of a lifter unit for maintaining the level of the topmost sheet of the sheets loaded in a sheet holding unit at a substantially constant height is made movable along the direction of removal of the sheet holding unit in order to move the moving lifter away from the sheet holding unit if the lifter being released downward gets caught by the sheet holding unit being removed, thus allowing reliable removal of the sheet holding unit.
