Optical arrangement especially suitable for use in a high speed

Abstract

A high speed multi-magnification photofinishing printer for selectively projecting images onto a projection plane containing photographic paper at a plurality of different magnifications is disclosed herein. This printer includes means for supporting a given image bearing photographic negative, means cooperating with the negative for producing a given image bearing light beam, and a plurality of spaced apart but fixed magnification lenses, each of which is designed to project the given image bearing light beam onto the photographic paper contained within the projection plane at different magnifications. The printer also includes light beam position altering means for selectively and alternatively causing the image bearing light beam to pass through any one of the plurality of fixed magnification lenses and onto the photographic paper, whereby to selectively and alternatively project the image bearing light beam onto the paper at one of the different magnifications. As disclosed, this light beam position altering means is comprised of an array of planar mirrors fixedly mounted on a movable carriage in a particular way.
