Abstract

In reproducing apparatuses which include an optical system for viewing an object and for projecting an image thereof onto a photosensitive surface selectively at one of a plurality of copy image magnifications, there is a need for margin illum-ination of the photosensitive surface when making reduced sized images. The margin illumination system 1, herein, utilizes stray light derived from the lamp of the optics system for illuminating margin regions of the photosensitive surface 2.
