Abstract
Cassette pour disque magnétique. La cassette comprend un ressort de compression 24 pour solliciter un plongeur vers une position enfoncée contre un ensemble de disque de mémoire 14, pour retenir le disque par friction à l'intérieur du boîtier 12 lorsque la cassette est retirée de la machine de lecture. La cassette comprend une porte d'accès qui est reliée au plongeur 22 par un ressort de tension 34 qui sollicite la porte vers sa position fermée lorsque le plongeur est en position enfoncée, et qui sollicite le plongeur à l'encontre du ressort de compression 24 vers une position rétractée espacée de l'ensemble de disque permettant rotation de ce dernier lorsque la porte est ouverte par une machine d'entraînement du disque. Application notamment aux ordinateurs.
