Abstract
PURPOSE:To control the starting of a recording and scanning with a reading signal, by scanning a photoreceptor with a deflected light flux, recording an image on the photoreceptor, and reading a timing mark recorded on the photoreceptor in advance with a light flux not deflected. CONSTITUTION:When a scanning line scans a transparent section, and when a mark detector 29 detects an optical signal of the transparent section of a timing mark, a mark detecting output is outputted, and when the next scanning line scans an opaque section, the mark detector 29 detects the optical signal of the opaque section, and the starting of recording scanning of laser beam is controlled. When a recording and scanning for one scanning line's share is finished, the laser beam is once turns off. When the laser beam turns on and the mark detector 29 detects the timing mark, a high frequency signal of an optical deflector is applied, the recording and scanning of a picture is started, the laser beam turns on and off with an image signal digitizing a read-in signal from the reading section and the image is recorded on a film.
