ABSTRACT:
A copy machine for producing both acceptable direct image copies and acceptable reverse image copies in a single machine from the same original object, comprises two independently contained, optical element assemblies mounted side by side and movable selectively into and out of a coping position, and strategically placed light baffling and light blocking devices, all of which combine to overcome the prior art problems of poor focus, poor clarity and poor light distribution.
