Abstract
Système de déflexion d'unité de film, pour un appareil de prise de vues à autodéveloppement. Une surface de came fixe et une bande de déflexion élastique introduisent une courbure longitudinale locale dans une unité de film lorsqu'elle avance sur une partie relativement courte d'un trajet de traitement depuis le contact entre une paire de rouleaux de traitement vers une fente de sortie. La bande est fixée de façon que son bord libre intercepte l'unité de film. La bande elle-même fléchit par suite de son contact avec l'unité de film et exerce une force élastique qui produit dans le film la courbure longitudinale locale qui favorise la répartition d'une composition de traitement photographique en une couche sensiblement uniforme sur toute la zone photosensible. La bande est disposée de telle façon qu'elle ne gêne pas l'éjection d'un cache de protection et d'écran relativement rigide conditionné avec les unités de film.
