PURPOSE:To photograph a data image of high quality with small-sized and low- priced constitution by using a negative and a positive lens for a data lighting optical system, and by exposing the back of a film directly to light passed through a data display body. CONSTITUTION:When light source 10 turns on, light come out from an illumination light emission exist 12 reaches a reflecting mirror 15 through a negative lens 13 and a positive lens 14. Light reflected by the reflecting mirror 15 passes through a mask plate 16 and liquid crystal 18 and reaches the back surface of a film 21 through a hole 20a made in a film press plate 20 to photograph a data image, displayed by a displat body 18, on a film 21. The mask plate 16 is placed right before liquid-crystal supports 17 and 19 to light only a data part while shielding other parts. |
