Abstract

Apparatus for reading and electrophotographic reproduction of microphotographs including an exposure station where copy paper is held stationary while a corona charging device is moved therealong to charge the copy paper appropriately for positive and negative reproduction, a screen for reading microphotographs, an optical system transmitting a light image of a microphotograph to either the reading screen or the exposure station dependent upon the pivotal position of a mirror, a developing station including a toner applying member responsive to pivotal movement of the mirror from the reading position to the reproduction position to move from a retracted position out of the path of copy paper through the developing station to a developing position to contact copy paper and apply toner thereto, and a control system for automatically controlling the apparatus to provide electrophotographic reproductions.
