Abstract

a. Dispositif de positionnement pour transducteurs. b. Dispositif pour entraîner un chariot portant un transducteur de façon intermittente le long d'une trajectoire par rapport à un support d'enregistrement utilisant une courroie formant une boucle sans fin qui est tendue en passant autour d'au moins une poulie libre et qui est reliée au chariot. Les extrémités de la courroie s'enroulent suivant des directions opposées autour d'un cabestan entraîné par un moteur pas à pas et leurs extrémités sont fixées à celui-ci à des emplacements espacés le long de son axe. La courroie et les poulies sont arrangées pour que les segments enroulés autour du cabestan restent parallèles à la trajectoire du chariot afin de faire avancer ce dernier d'un nombre maximal d'incréments le long de sa trajectoire. c. S'applique aux appareils d'enregistrement et concerne plus particulièrement l'entraînement du transducteur de lecture et d'enregistrement de ces appareils.
