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： A tape cassette housing capable of ensuring safety of a tape cassette in non-use of the tape cassette or during storage and transportation of the tape cassette. The tape cassette housing includes a housing body, a cover, a hinge for relatively openably connecting the housing body and cover to each other, and one or two pairs of projections provided on an inner surface of one of the housing body or cover. The projections are arranged in a manner to positionally correspond to pressing members of a tape cassette for holding reels of the tape cassette through the pressing members when the tape cassette housing is closed while receiving the tape cassette therein, to securely hold the pressing members, resulting in rendering the reels immovable in the tape cassette without any clattering. The housing may be provided with a locking mechanism for locking the housing body and cover together when the tape cassette housing is closed, to thereby further enhance safety of the tape cassette.
