Abstract

Dispositif à disque à insérer acceptant des disques de diamètres différents, présentant une épaisseur réduite et permettant le montage fiable d’un disque sur un moteur d’entraînement. Le dispositif à disque comporte un capot extérieur de châssis dans lequel est ménagée une ouverture d’insertion de disque dans laquelle un disque peut être directement inséré. Le dispositif à disque possède en outre un tiroir intérieur mû par un mécanisme à coulisse dans les directions avant-arrière entre le côté avant et le côté arrière du capot extérieur de châssis. Le tiroir intérieur comporte au moins trois parties de maintien servant à soutenir le disque. Une partie de contact de disque d’un levier de chargement (R), autrement dit la première partie de maintien, soutient un côté du disque. Une partie de contact de disque d’un levier de sélection, autrement dit la deuxième partie de maintien, soutient la partie arrière du disque. La position de rotation du levier de chargement (R) détermine la position d’arrêt du levier de sélection au niveau du côté arrière.
