Magnetic tape cassette having a slider mounted on the lower casing member

Abstract

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.
