Abstract: A variable magnification copying apparatus for obtaining a copy changed in size from an original pattern comprises an optical system having an optical axis, a movable carrier on which the optical system is mounted so as to be movable with the carrier and a D.C. motor mounted on the carrier. The carrier is reciprocable relative to a chassis of the copying apparatus in the direction of the optical axis between at least first and second position. The D.C. motor drives the carrier in a self-propelled manner relative to the chassis in the direction of the optical axis between at least first and second positions to thereby move the optical system between at least corresponding first and second positions to enable respective different sizes of the original pattern to be made at the corresponding first and second positions of the optical system.
