ABSTRACT:
An electrophotographic copying apparatus which is capable of copying in different copying magnifications from an original to be copied onto a copy material. The copying apparatus includes an optical unit having a frame, and a lens and at least one reflecting mirror attached to the frame as one unit so that accurate variation in the magnifications is readily achieved by merely displacing the optical unit in parallel relation to its initial position.
