Abstract
(DE)
Anordnung zur Erfassung der Bewegungsrichtung und Bewegungslänge beim Transport eines mindestens eine Perforationslochreihe (12, 13) aufweisenden Laufbildfilmes (1) mit einer der Bewegungsbahn des Laufbildfilmes (1) im Bereich der Perforationslochreihe (12) angeordneten Sensoreinrichtung, die aus zwei zueinander beabstandet angeordneten, berührungslos arbeitenden Sensoren (31, 32) besteht, deren Abstand A bei einer Perforationslochteilung T und einer Perforationslochweite L: A = n . T ± L/m, wobei n eine ganze Zahl grösser oder gleich 1 und m eine ganze Zahl grösser gleich 2 ist.
(EN)
Disclosed is a device for determinig the direction of motion and distance moved of a motion-picture film (1) with at least one row of sprocket holes (12, 13). The device has a sensor unit located in the path of motion of the film (1) in the region of the sprocket holes (12). The sensor unit comprises two sensors (31, 32) disposed a certain distance apart and working without physical contact, their distance apart A being given, for a sprocket hole pitch T and sprocket hole diameter L, by: A = n . T ± L/m, where n is a whole number greater than or equal to 1 and m is a whole number greater than or equal to 2.
(FR)
Agencement pour la détermination du sens de mouvement et de la longueur de mouvement lors du transport d'un film cinématographique (1) présentant au moins une rangée de trous de perforation (12, 13), comportant un dispositif de détection disposé sur le trajet du film cinématographique (1) dans la zone de la rangée des trous de perforation (12), ce dispositif de détection étant constitué de deux détecteurs fonctionnant sans contact (31, 32) éloignés l'un de l'autre, dont la distance A, avec un pas de perforation T et un diamètre de perforation L, est calculée comme suit: A = n . T ± L/m, où n est un nombre entier supérieur ou égal à 1, et m un nombre entier supérieur ou égal à 2.
