Abstract

L'invention porte sur un appareil de sélection de disques comportant: un boîtier, une plaque circulaire, deux moteurs pas à pas et un circuit de commande. La plaque circulaire comporte: des fentes de rangement de disques optiques; des dents de comptage à raison d'une par fente; une tige de RàZ disposée en un point original de la plaque circulaire. Le boîtier comporte: un détecteur de la RàZ de la tige, un détecteur de la position des position. L'appareil comporte en outre: une ouverture de passage pratiquée dans la paroi latérale du boîtier; un rouleau de passage du disque optique correspondant à ladite ouverture de passage; et un détecteur du passage des disques optiques monté sur l'ouverture du passage. En fonction des informations recueillies par les différents détecteurs, le circuit de commande amène l'un des moteurs à faire tourner la plaque circulaire dans un sens, et l'autre à faire tourner le rouleau dans les deux sens. Le premier moteur actionne également un mécanisme à came poussant un disque dans une des fentes, tandis que le deuxième entraîne le rouleau. L'appareil a donc les fonctions suivantes: rangement automatique de disques optiques, gestion automatique de disques optiques, et gestion de données.
