Abstract

L'invention est relative à un cadre pour diapositives. Selon l'invention, l'un au moins des éléments de cadre présente, du côté tourné vers la diapositive, deux rainures situées le long des bords longitudinaux de la fenêtre, et deux baguettes étant prévues pour pouvoir y être insérées et y coulisser alors longitudinalement de façon limitée et portant des tenons ou agencements similaires adaptés à la perforation du film diapositif. Le cadre évité le gauchissement des films diapositifs et permet une projection exempte de flou.
