CA 2331104

A disc cartridge includes a disc casing having a disc chamber defined therein for rotatably accommodating the recording medium. The disc casing has a sensor hole and a slot defined in first and second wall portions of the casing that are opposed to each other. A safety device is disposed within the disc casing for preventing information recorded on the erasable recording medium from being erased inadvertently. The safety device includes a bearing bushing integral with the first wall portion, and a switching element connected at one end rotatably with the bearing bushing for angular movement between first and second operative positions. The sensor hole is adapted to be closed by the switching element when the latter is angularly moved to the first operative position.

L'invention porte sur une cartouche de disque comportant un boîtier entourant une chambre où tourne un disque d'enregistrement. Le boîtier présente un trou de détection sur une première paroi et une fente sur la paroi opposée. Un dispositif de sécurité placé dans le boîtier empêche d'effacer non intentionnellement un disque effaçable. Le dispositif de sécurité comporte une douille-palier intégrée à la première paroi et un élément commutant fixé par l'une de ses extrémités sur la douille-palier et pouvant pivoter entre une première position de fonctionnement et une deuxième. Le trou de détection est fermé par l'élément commutant lorsqu'il est placé dans la première position de fonctionnement.
