Abstract

Perfeccionamientos en cambiadiscos automáticos, caracterizados porque comprenden un plato giradiscos rotativo, un eje centrador colocado en el centro de dicho plato y que tiene un estante sobre el que se puede colocar una pila de discos, medios automáticos de cambio del disco operativos durante un ciclo de cambio del disco para depositar el disco inferior de dicha pilar sobre dicho plato, incluyendo dichos medios automáticos de cambio del disco una cuchilla sensora del último disco montada sobre dicho eje y que tiene una porción superior adaptada para coger el borde de dicho disco inferior en la proximidad de dicho estante, caracterizado por la previsión de medios operativos durante un ciclo de cambio del disco para mover dicha porción superior de dicha cuchilla en la dirección de dicho estante con una fuerza pequeña que es insuficiente para permitir a dicha cuchilla eyectar un disco si está montando un disco sobre dicho estante pero que es suficiente para desplazar dicha cuchilla a una posición de cierre en ausencia de un disco sobre dicho estante
