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 casing for a magnetic tape cassette capable of effectively and precisely actuating a slider. The casing includes a casing body having an upper casing member and a lower casing member joined together. The slider is slidably mounted on the lower casing member so as to cover at least a part of a bottom and a side of the lower casing member. The upper casing member is provided at a rear portion of both sides thereof with holding members through which the casing is grasped. The holding members are separated or isolated from the slider, to assure smooth sliding movement of the slider. The casing body may be provided on both sides thereof with reliefs which serve to prevent the holding members from interfering with movement of the slider.

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.
