ABSTRACT:
A document handling apparatus for use with a copying machine to copy either thin or thick documents. Two pairs of cooperating rollers located on top of the copying machine feed thin documents past an illuminating station. A carriage for supporting a thin or thick document is also located on top of the machine. For copying a thick document or for making multiple copies of a thick or thin document, the two pairs of cooperating feed rollers move out of the path of the carriage which travels across the illuminating station. The carriage is centered on its home position by a cam which is part of a slider bracket supporting structures. The slider brackets are manually or automatically raised and lowered. The rollers and the carriage are independently driven by the main motor of the copying machine through separate drive systems. Controls prevent the carriage from traveling too far in either direction and from moving when the feed rollers are in the path of the carriage.
