Abstract
A disk cartridge is provided which, with a small number of parts, can reduce manufacturing costs and facilitate assembly. In particular, the disk cartridge can be assembled easily even if a disk medium is small-sized. Case members of a same configuration are superposed together so as to form a case. Shutter members of a same configuration are disposed so as to correspond to openings of the case members. A lock member and a spring member are provided in common for the two shutter members. The case members of the same configuration and the shutter members of the same configuration are used, and only one lock member and only one spring member are provided. Thus, a number of parts can be reduced, manufacturing costs can be reduced, and assembly can be facilitated.
Claims7
A disk cartridge accommodating a recording disk, as an information recording medium, within a cartridge case, and being inserted into a loading portion provided at a disk drive device, the disk cartridge comprising:
- a pair of shell members having same configurations, and being superposed together along a thickness direction of the recording disk so as to form the cartridge case;
- window portions formed in shell members so as to face an information recording surface at one side of the recording disk;
- shutter members provided at the shell members so as to be movable between a closed position, at which the shutter member closes the window portion, and an open position, at which the shutter member opens the window portion;
- guide grooves formed in the cartridge case at one side end surface corresponding to a direction of insertion of the cartridge case into the loading portion so as to extend, respectively, from both end portions of the one side end surface toward a center, and when the cartridge case is inserted into the loading portion so as to be oriented to a predetermined orientation, one portion of a shutter opening/closing member provided at the disk drive device is inserted into the guide groove and the guide groove guides the shutter opening/closing member to move along an opening/closing direction of the shutter member;
- and
- dummy grooves formed in the cartridge case at another side end surface at a side opposite to the one side end surface in which the guide grooves are formed, so as to extend, respectively, from both end portions of the other side end surface toward a center, and when the cartridge case is inserted into the loading portion so as to be oriented oppositely to the predetermined orientation, the one portion of the shutter opening/closing member is inserted into the dummy groove and the dummy groove guides the shutter opening/closing member to move along the opening/closing direction and restricts movement, to the open position, of the shutter opening/closing member.
A disk cartridge accommodating a recording disk, as an information recording medium, within a cartridge case, and being removably loaded into a disk drive device, the disk cartridge comprising:
- a pair of shell members having same configurations, and being superposed together along a thickness direction of the recording disk so as to form the cartridge case;
- window portions formed respectively in the pair of shell members, each window portion facing a recording surface at one side of the recording disk;
- shutter members disposed at the pair of shell members, respectively, so as to be movable between a closed position, at which the shutter member closes the window portion, and an open position, at which the shutter member opens the window portion;
- a shutter pushing portion projecting, in the thickness direction of the recording disk, from each shutter main body portion of the shutter member which moves in a region facing the window portion, the shutter pushing portion being movable along a case front edge portion, which extends at the cartridge case substantially parallel to an opening/closing direction of the shutter members, while facing the case front edge portion;
- and
- guide grooves provided in the case front edge portion so as to extend, respectively, from both widthwise direction end portions toward a central portion, and when the disk cartridge is loaded into the disk drive device, a shutter opening/closing member provided at the disk drive device enters into the guide groove and the guide groove guides the shutter opening/closing member to engage with the shutter pushing portion which corresponds to a recording surface at one side of the recording disk at which recording surface information is to be recorded onto or read from.
