PURPOSE: To increase the processing speed of data processing including KANA (Japanese syllabary) and KANJI (Chinese character) over the entire part of the card processor without physical compact with paper and without mechanical impact force and to suppress noise as well as to reduce the size and weight of the device.

CONSTITUTION: The card processor having a laser printer which is inputted with electric signals of characters, figures, graphics, etc., and outputs the signals to the paper is constituted of a data control system 1 which converts the electric signals into the driving current of a semiconductor laser 6 by a controller 5 and turns a laser beam on and off, an optical scanning system 2 which scans the laser beam of this semiconductor laser 6 in an optical scanning section 7 on a photosensitive drum 8 and forms the output patterns formed of dots, and a recording system 3 which transfers and fixes the output patterns drawn on the photosensitive drum 8 to the paper by means of an electrostatic charging section 9, a developing section 10, a transfer section 11, a fixing section 12, a destaticizing section 13, and a cleaning section 14.
