Abstract

L'invention concerne un magasin léger qui stocke plusieurs disques optiques, et un changeur de disque compact, de grande capacité et extrêmement fiable qui sort un disque optique du magasin et procède à l'enregistrement/lecture. Ce changeur de disque utilise un magasin (2) qui peut être monté sur l'unité principale du dispositif de façon amovible, ledit magasin (2) étant divisé au moyen de plaques de séparation (4) de façon à enregistrer plusieurs disques optiques (5). Le magasin (2) est pourvu de courroies (8) qui sont étendues sur des rouleaux (9, 12) et mises en contact avec les disques optiques (5) en vue de transférer les disques optiques. Le changeur de disque fonctionne de façon à ce que les courroies (8) soient pivotées par un pignon d'entraînement (17) d'un rouleau (9) qui est connecté à un pignon d'entraînement externe (18) en vue de sortir les disques optiques (5) au moyen d'un transfert par rotation. Parmi les disques optiques (5) sortis, le disque optique (5) en face d'une fente (36) d'une plaque de régulation de disque (35) passe par la fente (36), et les autres disques optiques (5) frappent la plaque de régulation de disque (35) et s'arrêtent. Le disque optique (5) passé par la fente (36) est pris entre les rouleaux de transfert de disque (50, 51), puis transféré à un lecteur (60) pour enregistrement/lecture.
