Abstract

L'invention concerne une unité de disque comprenant un mécanisme de transport de CD qui comporte un rouleau (11) de transport pour l'introduction et l'extraction de CD de différents diamètres extérieurs, un mécanisme de rotation de levier de verrouillage permettant de tourner et de rétracter un levier de verrouillage (17) en position ne gênant pas un MD (cartouche) (24) lorsque le MD (24), déplacé au moment de l'insertion dans un porte-MD (25), est introduit; ce mécanisme permet en outre de faire revenir le levier de verrouillage (17) à une position initiale, au moment de l'extraction du MD (24). Il existe également un dispositif de transport de MD permettant d'assurer le transport du MD (24) lorsque le levier de verrouillage (17) est rétracté comme indiqué ci-dessus, et d'extraire le MD (24) lorsque le levier de verrouillage (17) est ramené dans la position initiale. Le mécanisme de transport de CD et le mécanisme de rotation de levier de verrouillage sont entraînés par un moteur commun.
