Abstract: In an electrophotographic copying apparatus, the document stack to be fed is curved when it rests on a fixed curved stack-holding tray. The document stack is lifted by a pair of lifting blades having the curvature of the stack which move horizontally relative to the ends of the stack to move in and out beneath the sides of the stack, and thereafter move vertically to lift the entire stack out of the path of the returning copy. A vacuum belt arrangement is provided for moving successive documents from the top of the stack into the electrophotographic copying machine. The document loops through the machine and returns at a lower level, aligned with an opening beneath the bottom of the stack. Moving belts running beneath the stack carry the returning document into alignment under the stack.
