Abstract

Mécanisme d'avance d'unités de film empilées à l'intérieur d'une cassette. Le mécanisme d'avance selon l'invention prend contact avec l'unité de film en évitant les limitations structurelles de longueurs conventionnelles. Dans un mode de réalisation un bras de prise en charge entraîne un bord arrière de l'unité de film sous un rebord marginal, le bras étant libre de se déplacer à l'intérieur sur une majeure partie de la longueur de la cassette. Dans un autre mode de réalisation l'unité de film est dirigée en avant à travers la fente d'accès conventionnelle de la cassette puis prend contact avec une marge frontale pour être tirée plus en avant Application notamment aux appareils de prises de vues à autodéveloppement.
