Abstract

In xerographic copier/duplicators having vertically moving platens and document handling systems which move with and are supported by the optics, subjects the optical drive mechanism to excessive loads. It is proposed in order to prevent such overloading, a large part of the load can be removed by means of flexator-type constant force springs which provide counterbalancing of the mass of the document handling device. For the facilitation of field installation, the counterbalancing hardware is preferentially located within the document handling device.
