摘要： An aperture device for use in an optical apparatus has a plurality of aperture blades which cooperate in collectively defining an aperture of a desired size. The inner edge of at least one of such blades defining one side of the aperture is uneven over at least part of the length of the inner edge. The spacing between adjacent relatively high portions and relatively low portions, as well as the depth, is smaller than the exposed length of the inner edge of each aperture blade when the aperture device has been operated to the minimum aperture size. Preferably, the spacing between adjacent crests or between adjacent high portions and low portions of the unevenness varies in a non-periodic manner.

摘要： A disc cartridge capable of ensuring its stable and positive operation without damaging a disc while satisfactorily producing a cleaning effect and maintaining adequate contact between the head of a cartridge operating unit and the disc. Each of a pair elastic members respectively mounted on the upper and lower inner surfaces of a casing forcibly presses a sheet-like liner situated between the elastic member and a disc against the disc through a projection portion having a predetermined length formed as part of the elastic member, resulting in the liner contacting the disc with a force at substantially a constant level for a long period of time.

摘要： A disc cartridge capable of preventing a recording surface section of a disc from being contacted with an inner surface of a casing so that the disc may be free from any damage. The disc cartridge includes steps or sheet-like members provided on the inner surface of the casing in a manner to be inwardly projected from the inner surface. The steps or sheet-like members are positioned so as to be engaged with a non-recording surface section of the disc to support the disc thereon, so that a clearance may be defined between the recording surface section of the disc and the inner surface of the casing.

摘要： A disc cartridge capable of holding a disc in a casing in a state of floating in a space in the casting to keep it in noncontact with the casing when the disc cartridge is not used. The disc cartridge includes an actuator arranged in a casing receiving a disc therein to releasable lock a shutter for a window and a disc receiver arranged in the casing and operatively connected to the actuator to selectively receive therein a part of a peripheral portion of the disc. The actuator is arranged to be slidable in a longitudinal direction of the disc cartridge to cause the disc receiver to be approachably moved with respect to the disc, so that the disc receiver may be engaged with the disc to rearwardly force the disc while keeping the disc in noncontact with the casing when the shutter is actuated to close the window and disengaged from the disc when the shutter is actuated to open the window.

摘要： A hub for winding a magnetic tape thereon comprises a clamp for retaining one end of a magnetic tape. The novel tape clamp comprises a substantially rigid upper web, a resilient lower web and a pair of legs depending from the ends of the upper web and connected to the ends of the lower web. The lower web supplements the resilient force of the legs. As the upper web is not subjected to a stress, the magnetic tape is wound properly on the upper web.

摘要： A tape cassette has a case with upper and lower halves and an open space at the front thereof. A magnetic tape housed in the case is wound around a pair of reels. A brake is slidably mounted on the inner surface of the lower half of the case to prevent the reels from being rotated. Part of a spring is attached to the brake. The spring has free ends and urges the brake in a direction. A device for positioning the spring includes a partition wall on the inner surface of the lower half of the case which partitions the open case from the inside of the case. An independent abutment member on the partition wall abuts the free ends of the spring.
