Abstract

L'invention concerne l'entraînement du film dans les caméras et les projecteurs de cinéma. Le dispositif d'entraînement de film de l'invention comporte des circuits électroniques qui commandent le servomoteur 21 de façon à assurer un positionnement extrêmement précis de chaque image dans la fenêtre 35 d'une fente de guidage. L'asservissement est réalisé à partir de signaux fournis par des moyens photoélectriques 51 qui travaillent au niveau de la fente de guidage, ce qui évite l'emploi de codeurs angulaires. Application aux caméras de cinéma portatives.
