Abstract

Une rainure de guide (415) pour le guidage d'un levier de guide (411) est dotée d'une rainure d'inclinaison (415C) qui s'incline à un angle d'au moins 0°, mais de 90° au maximum à partir d'une rainure linéaire (415B). Ainsi, lorsqu'une broche de guide (411B) est déplacée vers une partie avant (10A) le long de la rainure d'inclinaison (415C), le levier de guide (411) et une section de poussée et d'expulsion (412C) disposée sur une section de rattachement d'un guide de disque (412) se tournent vers la partie avant (10A), poussent et expulsent le disque optique vers l'extérieur de manière à l'éjecter. Même un disque présentant une petite taille de diamètre peut être, facilement et en toute sécurité, retiré et l'efficacité du transfert est, donc, améliorée.
