Variable magnification reproducing apparatus

Abstract From the Canadian patent

A multi-mode reproducing apparatus which includes means for copying documents selectively at a plurality of copy image magnifications. An imaging surface is arranged for movement at a given velocity. Optical elements are provided for viewing a document and for projecting an image thereof onto the moving imaging surface. The optical elements include a first stationary lens for projecting the image onto the surface at a first projected image magnification and a, second lens arranged for movement between a first stored position where it is inoperative and a second position where it is operative to project an image of the document onto the surface at a second projected image magnification …
