Title (EN) DISK CARTRIDGE HAVING SHUTTER AND A DEVICE FOR OPENING AND CLOSING THE SHUTTER
(FR) CARTOUCHE DE DISQUES POSSEDANT UN OBTURATEUR ET DISPOSITIF D'OUVERTURE ET DE FERMETURE DE L'OBTURATEUR
Abstract:
(EN) Disk cartridge (1) having a shutter (9) that slides only on one side of a cartridge (5) to open or close the openings (7) and (8) where there are disposed pick-up devices (44) that are located on the upper and lower surfaces of the cartridge (5) to read or rewrite signals, the cartridge (5) holding a disk (6) which can record data signals on both sides thereof, such as an optical disk. The invention further relates to a device for opening and closing the shutter of the cartridge (1) in which a pair of shutter opening/closing arms (51) and (52) are disposed facing the direction for inserting the disk cartridge (1), in order to open or close the shutter (9) of the disk cartridge (1). A protuberance (57) or (58) is brought into engagement with an engaging hole (29) of the shutter (9), whereby the arm (51) or (52) is turned as the cartridge (1) is inserted, and the shutter (9) slides to open the openings (7) and (8). When the disk cartridge (1) is improperly inserted, the protuberance (57) or (58) is not engaged with the engaging hole (29), whereby the disk cartridge that is improperly inserted is detected.
(FR) Cartouche de disques (1) possédant un obturateur (9) qui coulisse uniquement sur un côté d'une cartouche (5) pour ouvrir ou fermer les ouvertures (7 et 8) où sont disposés des capteurs (44) situés sur les surfaces supérieure et inférieure de la cartouche (5) pour lire ou réécrire les signaux, la cartouche (5) contenant un disque (6), tel qu'un disque optique sur les deux faces duquel il est possible d'enregistrer des signaux de données. L'invention se rapporte également à un dispositif d'ouverture et de fermeture de l'obturateur de la cartouche (1) dans lequel une paire de bras (51 et 52) d'ouverture/fermeture de l'obturateur sont orientés dans la direction d'insertion de la cartouche de disques (1) afin d'ouvrir ou de fermer l'obturateur (9) de la cartouche de disques (1). Une protubérance (57 ou 58) s'engage dans un trou d'engagement (29) de l'obturateur (9), ce qui fait tourner le bras (51) ou (52) à mesure que la cartouche (1) est introduite, l'obturateur (9) coulissant pour ouvrir les ouvertures (7 et 8). Lorsque la cartouche de disques (1) est introduite de manière incorrecte, la protubérance (57) ou (58) ne s'engage pas dans le trou d'engagement (29), ce qui permet de détecter l'introduction incorrecte de la cartouche de disques.
