摘要： A disc cartridge includes a cartridge main body composed of a lower shell, in which a first opening that enables disc access for a disc-like recording medium in a housed state is formed, and an upper shell, a disc tray that is rotatably provided inside the cartridge main body and formed so that the recording medium can be mounted thereon, and a single shutter member disposed between the lower shell and the disc tray. A second opening, which enables disc access for the recording medium when the second opening overlaps the first opening in a thickness direction of the disc cartridge, is formed in the disc tray. The disc tray closes part of the first opening in a restricted state where the disc access is restricted, and is capable of opening the part of the first opening in a disc access state by being rotated inside the cartridge main body and causing the shutter member to slide. The shutter member closes another part of the first opening in the restricted state so as to close the first opening in concert with the disc tray, and in the disc access state the shutter member is caused to slide by the disc tray so as to be capable of opening the other part of the first opening.

摘要： A clamping plate includes a circular-plate-shaped main plate and a cylindrical outer wall formed by bending an outer edge portion of the main plate. The clamping plate moves due to being pulled by magnetic attraction by a disc rotating mechanism to clamp a disk-shaped recording medium to the disc rotating mechanism. At least one of a convex that protrudes outward in a radial direction of the main plate and a concave that is depressed inward in the radial direction is formed in the outer wall.

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.
