ABSTRACT:
A multi-mode reproducing apparatus having an improved system for positioning the viewing and projection elements therein for purposes of moving original exposure. Variable magnification copying is provided by holding a scanning mirror system in a fixed position to view a document which is advanced past its viewing domain. A system for repositioning the mirrors for conjugate change in accordance with one embodiment includes a device for uncoupling one of the mirrors from the drive system through the use of a selectively actuable stop mechanism and a quick-connect and disconnect type of coupling between the drive system and the mirror. In accordance with an alternative embodiment a friction clutch and selectively actuable stop mechanism allows one mirror to be stopped while another one continues to be driven to its stop position. When the mirrors are returned to their home position their original coordinated arrangement is restored.
