ABSTRACT:
A movable document handling system, or module, is utilized on a modified standard office copier. When the document handling module is moved away from the platen glass area, the document handling module equipment is disabled and the office copier may be used as a standard copier. When, however, the document handling module is moved over the platen glass, other optics and document handling apparatus are now energized and the standard office copier is now converted into a large document copier. The document handling module can be operated in either of the two positions for service and maintenance. Dual sets of gas spring apparatus is provided, wherein one or both gas springs in each set are in use for increased mechanical assistance in raising the document handling module when in place over the standard glass platen area. When the module is positioned away from the platen area, less mechanical assistance is required due to the shift on the module's center of gravity and only one in each dual sets of gas springs are allowed to actuate, said selective operation being controlled by the requisite mechanical linkages and assemblies.
