摘要： A tape cassette having a synthetic resin casing accommodating a tape-like medium composed of an upper half casing, a lower half casing and a front lid, the upper and lower half casings being integrated by a plurality of fixing portions. A plurality of fixing portions are disposed at first positions which are outside of a second position of the front lid. Slackening of screw fixation of the upper and lower half casings is preventing and incapacitance in rotating the front lid due to melt-bonding of the front lid and the upper half casing is avoided.

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.
摘要翻译：一种盒式磁带盒，能够确保盒式磁带在不使用磁带盒时或磁带盒的存放和运输过程中的安全性。带盒壳体包括壳体，盖，用于将壳体和盖彼此相对可开启地连接的铰链，以及设置在壳体或盖中的一个的内表面上的一对或两对突起。当盒式磁带外壳在其中接收盒式磁带的同时关闭时，这些突起以与位于盒式磁带的按压部件的位置对应的方式布置，以便牢固地保持按压部件，从而产生在使卷盘不可移动的磁带中没有任何咔嗒声。壳体可以设置有锁定机构，用于当带盒壳体关闭时将壳体主体和盖子锁定在一起，从而进一步增强带盒的安全性。
