ABSTRACT:
An optical system is disclosed for substantially doubling the capacity of a photocopying apparatus or the like. It provides alternative modes of operation; adjacent imaging of adjacent objects or double imaging of a single object. In the adjacent imaging mode, a single projection lens projects adjacent images of two adjacent objects in a straightforward way. In the alternative double imaging mode, a pair of projection lenses projects twin images of a single object along "parallel" optical paths.
