Filed:

Jul 14, 1983

Appl. No.:

6/513884

Inventors:

Russell A. Temple - Sierra Madre CA
Martin G. Wesseler - Arcadia CA
David C. Harper - Claremont CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 2100

US Classification:

355 3R

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. A fold mirror in a first position directs reflected light from the large input document through the standard platen glass for 100% size copying. The fold mirror can be repositioned to reflect the reflected light toward a reduction mirror assembly which then directs the light through the standard platen glass for reduced size copying. The reduction mirror assembly is capable of being repositioned to provide various predetermined amounts of optical reduction.

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. Additional mechanical apparatus moves lenses in a predetermined fashion in the document handling module in order to allow for various levels of magnification for reducing the size of the copy from the large input document.
