MULTIBEAM RECORDING DEVICE

摘要

PURPOSE:To provide a multibeam recording device capable of recording the picture of high quality by simple adjustment. CONSTITUTION:An aperture plate 10 is arranged between a light source unit 5 in which plural light source parts 1 individually generating a single light beam are arranged in a prescribed arrayed pattern and a reduction optical system (image-forming optical system) 40. Plural apertures 9 are formed on the aperture plate 10 in the same arrayed pattern as that of the light source parts 1. The light beam from each light source part 1 is introduced into the reduction optical system 40 through an aperture 9 facing the light source part 1 and the reduced image of the aperture 9 is formed on a photosensitive material PM. Consequently, the image of the aperture 9 is formed on the photosensitive material PM even when the light source part 1 is positioned on the slightly deviated position from a prescribed arrayed pattern. Thus, the positioning adjustment of the light source part 1 is simply performed and the picture of high quality is recorded.
