Abstract: PURPOSE:To obtain a toner image of the resolution of 6 lines/mm by combining an electronic mirror with a small spot diameter with a thin film fluorescent screen with little beam scattering in the film, with an electro-optical system to obtain an image of high resolution, and projecting on a flat plate photosensitive body by an optical system. CONSTITUTION:Because a two dimensional image of great brightness can be obtained by a projection type cathode ray tube with the thin film fluorescent screen, a speedy recording and transferring can be carried out with this image as a light source. For example, in order to project a beam of 0.1mm width on a photosensitive material of A4 size, a luminescent line of 0.05mm width is drawn on a projecting tube with a screen size of 5 inches in diagonal line length, and a projecting lens with a magnification ratio of 2.0 is utilized. When a single crystal thin film is utilized, the cathode ray tube size can be made smaller by stopping the fluorescent spot diameter to 10mum and enlarging the lens enlargement ratio. In general, in comparison with a powder fluorescent screen, the thin film fluorescent screen is more dense with better heat conductivity, has little temperature rise by irradiating of electron beams, and has little lowering of light emitting efficiency by the rising of the temperature and deterioration by irradiation of electron beams.
