Abstract

Abstract Translated from German Die Erfindung betrifft eine Rollfilmkassette, bestehend aus einer spulenlosen Vorratskammer und einer durch einen Steg mit dieser verbundenen Aufwickelkammer, in welcher mittels einer Spule der belichtete Filmstreifen und der Schutzpapierstreifen aufgewickelt werden. Zur Verhinderung des Einziehens des Filmstreifenendes in die Aufwickelkammer ist ein federndes Element an der Kassettenrückwand so angebracht, daß dieses in ein Filmloch eingreift und den Filmkanal zur Aufwickelkammer blokkiert. The invention relates to a roll film cassette, consisting of a spoolless storage chamber and a winding chamber connected to it by a web, in which the exposed film strip and the protective paper strip are wound up by means of a spool. To prevent the filmstrip end from being drawn into the take-up chamber, a resilient element is attached to the rear wall of the cassette so that it engages in a film hole and blocks the film channel to the take-up chamber.
