ABSTRACT:
A writing system is usable in apparatus in which mirrors in a "V" configuration, split mirrors, a combining mirror and a camera mirror project images of opposite sides of a document in an imaging region to a microfilm in side-by-side relation. The writing system includes mirrors which project alpha or numeric character images from an LED display to the combining mirror to be projected to an otherwise unused portion of the microfilm. A compact folded path is provided having the same focal distance as that provided by the document image projecting mirrors.
