ABSTRACT:
The utility of a document exposing system for a copying machine that has a separate exposure platen for bulky documents with a cover containing a transport mechanism, is improved by providing for the platen cover to swing up and away from the platen by being pivoted on a horizontal hinge axis that is remote the rear edge of the platen and by providing for the single sheet document feeder to pivot away from the side of the platen by turning about a vertical axis located behind the back edge of the platen. Thus, an open, unobstructed volume over and at the side of the platen is provided whereby pages of extremely large bound volumes may be copied.
