ABSTRACT:
A microfilm viewer/printer projection system particularly adapted for full plane plain paper copying has a first, a second and a third mirror which selectively project a document image from a horizontal object plane to a vertical viewing plane or a horizontal exposure plane. In the view mode, the first and second mirrors reflect the document image to a screen which defines the viewing plane. An AC motor movement drives the first and second mirrors to a print mode, in which the second mirror is parked in a parking zone which is enveloped by the projection path from the object plane to the exposure plane, which is defined by a belt type photoreceptor. In the print mode, the first mirror reflects the entire document image to the third mirror, which is a black mirror, and the third mirror reflects the entire document image to the photoreceptor, to expose the photoreceptor to the entire document image simultaneously.
