ABSTRACT:
The surface of an original is scanned in the direction of lines with a laser beam to obtain read-out data from the reflected light beam from the original, and the read-out data for a line are first stored in a line buffer memory. Then, during the scanning for the next line by the laser beam the data which have been stored in the line buffer memory are read out and used to modulate a laser beam, with the laser beam thus modulated being led to a light-sensitive drum for making duplication of information of the read-out data.
