Abstract

L'invention concerne un appareil d'éjection/de verrouillage de magasins permettant d'éjecter aisément un magasin d'un changeur de disques compacts. Cet appareil d'éjection/de verrouillage comprend un élément coulissant vers l'avant et vers l'arrière placé sur une paroi supérieure d'une partie de magasin, et un linguet élastique comportant une projection articulée à une paroi inférieure de la partie de magasin, et reliée à une rainure de linguet du managsin et à une molette d'éjection s'étendant à partir d'un côté du linguet élastique dont elle est solidaire. L'élément coulissant coulisse vers l'avant et vers l'arrière sur la paroi supérieure de la partie de magasin, et est décalé vers l'avant de la partie de magasin par deux ressorts de torsion. Le linguet élastique est articulé par une barre d'articulation autour de laquelle est enroulé un ressort hélicoïdal. Une première extrémité de cette barre est supportée sur un côté de la partie de branche et une deuxième extrémité étant supportée vers une position prédéterminée de la paroi inférieure de la partie de magasin de manière à décaler le linguet élastique. Ce dernier tourne lorsque la molette d'éjection est déplacée manuellement. Lorsque cet appareil de verrouillage/d'éjection de magasin est utilisé sur un changeur de disques compacts, la configuration de la partie de magasin est simplifiée et il est possible d'éjecter manuellement un magasin.
