Abstract
A sheet feeder for an electrophotographic copier or like image forming apparatus includes a structure for aligning the trailing edges of a large amount of paper sheets which are stacked on a tray. The structure includes a back fence mounted on a transmission member which is stretched in the widthwise direction of the sheets. The back fence is movable in the widthwise direction of the sheets between an operative position for aligning the trailing edges of the sheets and an inoperative direction for facilitating the supply of sheets onto the tray. The movement of the back fence between the operative and inoperative positions is interlocked with the upward and downward movements of the tray.
