Abstract

Certain designs of paper feeding devices used in copiers and printers require that an edge of a stack of sheets be in close contact with a slanted surface. An apparatus engages an opposite edge of the stack to urge the stack against the slanted surface, so that the stack assumes a parallelogram shape. The apparatus includes a plate which is movable from a vertical, upright position to a slanted position. Means are provided to cause the plate to move to the slanted position in response to the closing of a paper tray of a printer or copier.
