<p>PURPOSE:To enable a latent image to be formed easily on a photosensitive medium such as a photosensitive drum by providing a light source system which projects light to a surface between the upper layer substrate and base substrate of a light signal generation device and an image condensation optical system which condensates an image at a specified position using a light signal emitted from the light signal genera tion device. CONSTITUTION:A light source system 20 emits a parallel beam to a light signal genera tion device 10 and therefore, a light emitted from a collimator lens 24 travels parallel to the entire longitudinal direction of a convex glass 12. In addition, a photosensitive medium 30 forms a latent image using a reflective light controlled by the light signal generation device 10 after being emitted from the light source system 20. An ordinary photosensitive drum is used as the photosensitive medium 30. In addition, a lens system consisting of refractive index distribution-type lens arranged in a dumbbell form is used as an image condensing optical system 40. The refractive index distribution-type lens is formed so that the refractive index is radially distributed to the periphery from the center of the lens. In addition, the lens can be installed a few mm to scores mm close to an object point and an erect magnification image can be focused.</p> |
