ABSTRACT:
A beam scanning type electronic copying apparatus is provided in which document information is read out according to a beam reflected based on a scanning laser beam, the laser beam is modulated according to the document information and a record medium is exposed while being scanned. The laser beam scans the document and record medium simultaneously through an aconstooptic element which permits simultaneous beam diffraction and beam modulation. The readout of the document information and recording are simultaneously effected using the same optical system.
