Abstract
The present invention relates to a driving apparatus for the optical systems of a photocopier comprising 1st and 2nd optical systems, 1st and 2nd wires stretched out facing with each other through the wire-fixed ends of the 1st optical system, moving pulleys of the 2nd optical system, fixed pulleys of both systems and a common wire drum for both wires. The common wire drum has two wire drum bodies with a shallow and smooth dented portion, and a screw for pressing and fixing the approximate center of the wires against the bottom surface and/or side surface of the dented portion.
