摘要： A magnetic tape cassette capable of improving sealing of the tape cassette when it is out of use, to thereby positively protect a magnetic tape arranged therein. The magnetic tape cassette includes an openable front lid and a rear lid arranged so as to cover a front opening of the tape cassette casing and is so constructed that the front and rear lids are provided with facing portions, respectively, which are arranged so as to face each other along an arc defined by the facing portion of the rear lid when the rear lid is pivotally moved relatively to the front lid to cover the protecting space for the magnetic tape and each lid is formed into an arc or slanting plane, resulting in the lids being closely associated with each other to a degree sufficient to ensure satisfactory sealing of the cassette when the front lid is pivotally moved to cover the opening of the casing.

摘要： Elastic lifters arranged on an inner surface of a casing of a disc cartridge to act pressing force on a disc each are formed integral with the casing and into a plate-like shape in such a manner that a proximal end thereof is mounted on the casing and the a 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-like medium, 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.

摘要： A disk cartridge has a disk accommodated in a casing having a center aperture and access windows. A pivotal shutter is pivotally mounted for closing the center aperture. A rotary shutter is rotatably mounted for closing the access windows and interlocked with the pivotal shutter. A first slidable member is cooperatively coupled to the rotary shutter, and a second slidable member is opposed to the first slidable member and adapted to be slid upon engagement with a shutter actuating member when a disk drive is loaded with the disk cartridge. The first and second slidable members having racks on their opposed surfaces interlocked through a gear mechanism for transmitting the motion of the second slidable member to the first slidable member, which in turn, drives the rotary shutter.
