摘要： A disc cartridge of a three-piece structure capable of enhancing moldability and rigidity of a center frame. The center frame having a square-like shape is interposedly arranged between an upper plate and a lower plate and has a receiving space defined therein for receiving a disc-like medium. The upper and lower plates are provided on four corners thereof with fixing bosses respectively. The center frame is formed on opposite surfaces thereof with fitting recesses in which the bosses are fitted, respectively. The center frame is formed on each corner thereof with a thin-wall portion having a reduced thickness of 50 to 80% based on a whole thickness of the center frame.

摘要： A storage case includes a main body and a cover member so supported by rotary spindles as to be rotatable with respect to the main body and rotatable between an opening position and a closing position. The cover member includes cartridge holding members, formed on right and left sides thereof, for holding and integrally rotating a cartridge inserted into between the main body and the cover member when the cover member rotates to the opening position. When the cover member is closed, an opening, which permits an insertion of a mini disk from outside, is formed between the main body and the cover member. The cover member is opened, whereby the mini disk encased in the storage case also rotates, and hence, even when an index card is disposed between, e.g., the mini disk and the main body, the index card can be taken out without pulling out the mini disk.

摘要： A disk cartridge is constituted by a case for holding a disklike medium therein, a slidable shutter, and a coil spring. The case has an upper case and a lower case coupled together. The upper case and the lower case is provided with a hole for inserting a record-playback head and a hole for inserting a driving shaft. The slidable shutter is substantially U-shaped in cross section, and exposes and blocks up the openings. The shutter is formed of a left-side shutter and a right-side shutter. The coil spring is stretched between retaining portions provided to the sliders of the respective left- and right-side shutters in order to urge the left- and right-side shutters in the direction of bringing both shutters close to each other. The left- and right-side shutters are abutted each other to block up the opening by the urging force of the coil spring. The left- and right-side shutters are slid in the direction of parting both shutters from each other against the tensile strength of the coil spring in order to expose the openings.

摘要： A cartridge receiving casing capable of permitting a cartridge to be readily removed from the casing by one hand as required while preventing the cartridge from accidentally falling off from the casing. The casing includes a casing body formed so as to be open on one side thereof to provide the casing with an opening through which a cartridge is inserted into and taken out of the casing and a cover slidably arranged on the casing body. The cartridge is engaged with first projections of stoppers at a received position, to thereby be elastically supported in the casing. When the cover is slid to an intermediate position toward the opening, the cartridge is partially exposed through the opening and elastically supported while being drawable out of the casing. Further sliding of the cover permits the cartridge to be removed from the casing.
