Title
(EN) DATA PHOTOGRAPHING DEVICE FOR CAMERA
(FR) DISPOSITIF DE PHOTOGRAPHIE DE DONNEES POUR UN APPAREIL DE PRISE DE VUES
Abstract
(EN)
A data photographing device for a camera in a data photographing optical system, which includes a transparent electrode (8) formed in the pattern to be photographed (9) and a liquid crystal member (4), in which the desired photographic data is formed by applying a voltage to the desired portions of the transparant electrode (8), making the portions of the liquid crystal over those portions of the electrode become light transmissible. A light shielding member (7) including a light transmissable portion having approximately the same shape as the pattern of the transparant electrode (8) is arranged at a position in such a manner that the light transmissible portion (10) is optically superposed with the transparent electrode (8), thereby blocking passage of light through the liquid crystal except through the pattern of the transparent electrode (8). Consequently, the data can be clearly photographed on a film surface.

Un dispositif de photographie de donnee pour un appareil de prise de vues dans un systeme optique de photographie de donnees, comprend une electrode transparente (8) formee avec le motif a photographier (9) et un organe de cristaux liquides (4), dans lequel les donnees photographiques desirees sont formees en appliquant une tension aux portions desirees de l"electrode transparente (8), et en rendant les portions de cristaux liquides sur ces parties de l"electrode transmissibles a la lumiere. Un ecran de lumiere (7) comprenant une partie transmissible a la lumiere ayant approximativement la meme forme que le motif de l"electrode transparente (8) est dispose dans une position telle que la partie transmissible de lumiere (10) soit superposee optiquement avec l"electrode transparente (8), bloquant ainsi le passage de lumiere au travers du cristal liquide a l"exception du motif de l"electrode transparente (8). En consequence, les donnees peuvent etre clairement photographiees sur la surface d"un film.
