A bypass document handler is also provided for receiving and advancing a document past the viewing station intermediately of the carrier and the station, wherein a microcomputer is responsive to rotation of the carrier for rendering the copying apparatus operable in synchronized relationship with the rotation of the carrier and/or the advancement of a document through the bypass document handler.
