ABSTRACT:
Disclosed is a platen cover for a copying machine in which the bound volume copying platen is not used for sheet document copying. The cover includes a sheet document transport and handling mechanism with the cover having an independently liftable lid to provide access to the transport and handling mechanism. Substantially uniform counter-balancing of the cover, containing the transport and handling mechanism, or the lid alone, from the closed hold-down position to the raised stay-open position, is provided by a torsional helix spring positioned about the pivotal axis of the lid counterbalancing the lid, and a gas spring acting on the transport and handling mechanism through a lever arm about the same axis, counterbalancing the mechanism.
