Abstract
A sheet feeder for feeding sheets into a copying or printing machine includes a movable base movably mounted on a fixed base for movement across a sheet inlet of the copying or printing machine in a direction perpendicular to the direction in which the sheets are fed into the copying or printing machines. Two sheet tables for carrying respective stacks of sheets thereon are juxtaposed along the direction in which the movable base is movable, and is mounted on the movable base, so that a selected one of the sheet tables can be positioned at the sheet inlet in response to movement of the movable base. The selected sheet table is lifted by a lifter mechanism associated therewith to elevate the supported sheets until the uppermost one of the sheets reaches a sheet feeding position. The sheets are then successively fed from the selected sheet table into the sheet inlet.
