Abstract
Commande et contrôle du mouvement d'un support d'enregistrement. Une commande applique à un dérouleur des impulsions d'entraînement dont chacune a une durée variable suffisante pour entraîner le dérouleur de manière que le support soit déplacé d'une distance prédéterminée. Une commande d'asservissement de vitesse transmet un signal d'entraînement continu ajustable au dérouleur, et un commutateur transfère la commande du dérouleur, de la commande d'entraînement par impulsions à la commande d'asservissement de vitesse, lorsque la vitesse du dérouleur atteint une vitesse de transition prédéterminée Applicable notamment aux magnétoscopes.
