ABSTRACT OF THE DISCLOSED EMBODIMENT In a dual mode copying system, where in one mode, document sheets are fed to the platen of a copier with a document feeder overlying the platen to be registered and copied, and where, in a second mode the document feeder is liftable away from the platen and the copier provides for alternative manual document sheet placement in a registration position on the platen defined by a registration edge guide projecting above the upper surface of the platen, adjacent one edge of the platen; dual mode document edge registration and edge guide means automatically repositionable between first and second positions at two different levels above the the upper surface of the platen, moving into the first position automatically in response to the lifting of the document feeder away from the platen to project a vertical document registration edge obstructing surface above the upper surface of the platen adjacent the platen, but which, in the second position is automatically pushed below that surface by movement of the document feeder towards the platen, and separate oppositely sloping, document edge guiding upper surfaces extending from below to above the upper surface of the platen even in the second position to provide ramp surfaces assisting the unobstructed movement of a document by the document feeder over the adjacent edge of the platen. -25-
