ABSTRACT:
An original sheet document for electrostatic reproduction is inserted into the mechanism face up, and the mechanism feeds and positions the document onto a glass platen face down. Endless belts are trained over pulleys forming a plurality of parallel runs which are disposed closely above the platen. Idler feed rollers are disposed above the pulleys which feed the document into engagement with a guide member which reverses the direction of movement of the document by 180.degree. and guides the document between the belts and the platen. The belts are oriented at an angle to the edges of the platen and move the document both forwardly and laterally across the platen. Elongated stops are provided at the edges of the platen toward which the document is moved by the belts, and the document aligningly abuts against the stops. The belts are arranged to yield upon said abutment. The stop at the forward edge is movable to allow the belts to move the document off the platen onto a receiving tray.
