Abstract
An image scanning and recording device includes a recording unit for duplicating and recording halftone images on a photosensitive material. The recording unit comprises a light source associated with an acousto-optic light modulating element including a plurality of ultrasonic wave exciting portions disposed in an array side by side on a single acousto-optic medium. The ultrasonic wave exciting portions each independently modulate incident light into the respective modulated light beams in response to image signals from photoelectrical scanning means. In addition means are provided for directing light from the source to the acousto-optic light modulating elements. Also provided are means for forming rows of tiny light spots corresponding to the modulated light beams on a recording material.
