Abstract
Mécanisme d'indexation de came de programmation comprenant une came de programmation rotative munie d'une surface de traction périphérique et d'une piste concentrique tournée vers l'intérieur possédant une ou plusieurs encoches pour définir des positions de programmes indexées, entraînée de façon rotative par une poulie d'entraînement accouplée à un arbre d'entraînement, et supportée par un élément de verrouillage pivotant sur l'axe dudit arbre d'entraînement. L'élément de verrouillage d'un seul tenant définit un suiveur et une patte de contact avec la surface de piste tournée vers l'intérieur sur la came de programmation pour maintenir la poulie d'entraînement en contact avec sa surface de traction périphérique, mais pour permettre à ladite poulie de basculer de son contact lorsque la patte de support de suiveur tombe dans les encoches de positionnement. Le déplacement hors des encoches est effectué par un électro-aimant. Applications notamment aux appareils de projection cinématographiques
