ABSTRACT:
An improved electrostatic photo-copying machine is proposed. In this improved photo-copier, an optical system for scanning a document from which photocopies are to be made is provided. However, the movable range of the optical system is divided into a front half and a rear half, adapted for execution of successive scannings so as to provide a book copy mode operation. If, however, an incompatible operation to the book copy mode, for instance, manual feed of any suitable size copy paper through a manual feed opening; automatic document feed mode or the like has been specified, the once and in advance selected-out book copy mode is automatically released from service.
