PATENTANSPRUCH:PATENT CLAIM: Bildwerfer mit selbsttätiger Signalgebung durch eine im Gleichschritt mit dem Filmbild bzw. Bildstrich laufende Kontaktrolle, welche über Leitungen und Relais mit den Betätigungselementen des Bildwerfers verbunden ist und mit im Filmband vorgesehenen Kontaktgebern in Form von in den Filmrand eingesetzten Metallösen zusammenwirkt, dadurch gekennzeichnet, daß der Zahnkranz der Kontaktrolle (b) in einzelne Kontaktsektoren (α) unterteilt ist, welcher entsprechend der Zahl der zu einem Filmbild gehörenden Perforationslöeher an der Kontaktrolle Schleifringe (d) so zugeordnet sind, daß die jeweils zum gleichen Perforationsloch eines Filmbildes gehörenden Einzelkontakte (α) untereinander und nur mit einem der Schleifringe leitend verbunden sind.Projector with automatic signaling by a contact roller running in step with the film image or image line, which is connected to the actuating elements of the projector via lines and relays and interacts with contactors provided in the film strip in the form of metal eyelets inserted into the film edge, characterized in that the The ring gear of the contact roller (b) is divided into individual contact sectors (α), which are assigned to slip rings (d) according to the number of perforation holes belonging to a film image so that the individual contacts (α) belonging to the same perforation hole of a film image are assigned to one another and are only conductively connected to one of the slip rings.
