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.

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.
