摘要： A disk cartridge has a casing of resinous material which receives therein a floppy disk in a rotatable manner, the casing being formed by combining upper and lower half casings with the use of connecting ribs formed on the inner surface of at least one of the upper and lower half casings. The upper and lower half casings respectively have an outer circumferential wall at the circumference of the inner surface and an annular rib at the inner portion of the outer circumferential wall so as to define a floppy disk rotating region, wherein projections are formed in the annular rib of the upper half casing. Recesses are formed in the annular rib of the lower half casing so that the projections and the recesses are fitted to each other in a non-contacting state so as to form a complete annular wall, and sealing ribs are formed on the outer surface of the annular rib of the upper half casing so as to extend over gaps formed at the fitting portion of the projections and recesses.

摘要： A magnetic tape cassette capable of effectively preventing separation of a slider from a casing even when it is dropped or any external force is applied thereto, resulting in ensuring its safety and reliability. The magnetic case includes a casing constituted by an upper casing member and a lower casing member and a slider slidably mounted on the lower casing member. Each of side walls of the slider includes a lower portion opposite to an outer surface of a side wall of the lower casing member and an upper portion opposite to an inner surface of the side wall of the upper casing member. The cassette also includes a mechanism for preventing the slider from being disclocated from the casing. The mechanism may be provided by positioning the inner surface of the side wall of the upper casing member inwardly from the outer surface of the side wall of the lower casing member. Alternatively, it may be provided by positioning the inner surface outwardly from the outer surface through a slit defined therebetween and forming the upper portion of the side wall of the slider into a thickness larger than the slit.

摘要： A disc cartridge capable of permitting a hub to be constantly rotated about the center of rotation thereof without any eccentricity, to thereby ensure smooth and stable rotation of the disc. The hub is formed with three drive shaft inserting holes in a manner to be spaced from each other at equal intervals and positioned on a concentric circle of a predetermined radius defined about a center of rotation of the hub. The drive shaft inserting holes each are formed with a linear driven surface which is adapted to be contacted with a drive shaft inserted into the hole. The driven surface may be arranged at an angle of -30 to +30 degrees with respect to the center of rotation of the hub.

摘要： An elastic lifter arranged on an inner surface of a casing of a disc cartridge to exert a pressing force on a disc is formed integrally with the casing and into a plate-like shape in such a manner that a proximal end thereof is connected to the casing and a distal end thereof is rendered free. Such construction permits the pressing force to be kept constant for a long period of time and effectively prevents damage to the disc, to thereby substantially improve durability and reliability of the disc cartridge while significantly decreasing the number of parts, facilitating assembling of the disc cartridge, and attains a decrease in manufacturing cost. The lifter may be formed at a proximal end thereof with a decreased thickness, to thereby facilitate bending of the lifter.

摘要： A disc cartridge capable of preventing entering of dust into a casing and ensuring a stable and positive operation without damaging a disc while satisfactorily exhibiting a cleaning effect and keeping proper contact between a recording head and the disc. A casing is provided thereon with a slide area which is formed by a slide area defining section of the casing. The slide area is formed with at least one head inserting hole. The slide area defining section is provided on an inner surface thereof with at least one thick-walled portion in a manner to extend along a whole periphery of a portion of the head inserting hole overlapping a sheet-like liner and inwardly project from the inner surface of the casing, so that the liner may be pressed against the disc at a force of a constant level over a wide area of the disc and block a communication between an exterior of the cartridge and its interior through the head inserting hole.
