Abstract: There is provided an electronic copying apparatus which scans an original with a scanning laser beam, modulates an exposure laser beam with an electric signal corresponding to the light reflected from the original, applies the modulated laser beam onto a sensitive member of an electronic photograph processing unit, thereby providing a copy of the original. External data are superposed on the data corresponding to the electric signal, and the exposure laser beam is modulated according to the superposed data, thereby making a copy containing the external data in addition to the information on the original.

Abstract: Disclosed is a scanning apparatus used in, for example, a facsimile copying device. A scanning mechanism carries out a time sequential scanning of a manuscript sheet by, for example, a laser. A photoelectric element holding block, having a slit for allowing the passage of scanning beams from the scanning mechanism, travels jointly with the time sequence scanning of the manuscript sheet. A plurality of photoelectric elements are set around the slit of the holding block.
