This invention relates to an automatic sheet-feeder for feeding a sheet from the bottom of a stack of sheets placed on a sheet tray and for circularly returning the sheet to the top of the stack. The sheet tray comprises a movable tray and a stationary tray, and the movable tray can move upward or downward in accordance with the size of the sheet, and further the movable tray comprises an intermediate sheet-feed to transport the sheet, whereby the edges of the pile of sheets are aligned in order to prevent erroneous sheet-feeding.
