Abstract

Le dispositif automatique d'entraînement du bras de lecture de l'invention comporte un dispositif de came 28 entraîné par un moteur 25 independant du moteur d'entraînement du plateau. Ce dispositif de came comporte des portions de cloison 29 entraînant le bras de lecture pendant ses déplacements entre son support de repos et sa position correspondant au début de lecture des disques par l'intermédiaire d'une liaison à friction 13, permettant ainsi de désolidariser le dispositif de came du bras de lecture pendant toute la durée de lecture des disques.
