ABSTRACT:
A copying apparatus operating either in a first image scan mode wherein a scan of an original at a standstill on an original table is performed by the movement of an optical system and the image is projected onto a photosensitive member, or in a second image scan mode wherein the optical system standing by a specified position scans an original being transported by an original transport unit and the image is projected onto the photosensitive member. Distance between a position where the optical system actually stops and a standard position where the optical system is supposed to stop is measured, and in an operation in the second image scan mode, the transport of an original and the supply of a copy sheet are adjusted in order to be synchronized with each other, according to the measured distance.
