Abstract

PURPOSE: To perform copying of the original simultaneously with its reading by reflecting the read beam light of the original on one reflecting surface of the reflecting mirror part of the light scanner and reflecting the beam light modulated according to the information thus read on the other reflecting surface thereby exposing the photoreceptor.
CONSTITUTION: The read beam l1 divided by a half mirror 12 from the beam light l0 from a laser oscillator 11 reflects on the 1st reflecting face 18a of a rotary reflecting mirror part 18 and scans the original 13. The light reflected from the original 13 is converted to an electric signal by a photoelectric transducer 21 and is amplified, after which this signal is supplied to a modulator driver 23 and becomes the modulating signal. A light modulator 24 modulates the exposure beam l2 divided from the beam l0 by the half mirror 12 according to said modulating signal. The modulated beam light l3 reflects on the 2nd reflecting face 18b of the rotary reflecting mirror part 18 and exposure-scans the photosensitive drum 14. In this way, the reading of the original 13 and the exposure to the photosensitive drum 14 are accomplished simultaneously, and the need for temporary memory part may be eliminated.
