PURPOSE:To obtain an extremely highly accurate and highly productive imprinting device without reducing in the segment of a liquid crystal panel to be used as a shutter in thickness and size by using a Fresnel lens. CONSTITUTION:In a copying device for imprinting characters for a camera in a film, a Fresnel lens (f) is arranged between the film and the liquid crystal panel having a shutter function and a polarizing plate arranged on the film side of the panel is constituted of a Fresnel lens consisting of a material having polarizing capacity. Thus, characters can be imprinted with contracted size. |
