Abstract

PURPOSE: To make it possible to make the gap between an original form surface and optical fibers wide sufficiently by placing one end face of optical fibers on the focusing face of a lens, which reads the original surface, and providing the other end face oppositely to photosensitive elements.
CONSTITUTION: Minute part S of original form 2 opposite to lens 7 is illuminated by the projection light from light source optical system 3, and lens 7 generates the real image of minute part S at the lower end face center of holder 9. This image of the original pattern of minute part S is focused onto the light receiving face of optical fibers 10W13, and fibers 10W13 induce incident lights to the photosensitive face of corresponding photo cells 16W19 respectively, and outputs according to incident lights are generated in photo cells 16W19. As the result, since even a normal single lens has a field depth over a normal form, resolution can be prevented from being lowered even if thickness of the form is changed.
