    • A tape cassette comprises a housing (1) and a pair of reels (4, 5) mounted for rotation and translation in the housing (1) so that the reels can assume either of first and second relative positions. A recording tape (T) is wound on the reels (4, 5) and extends therebetween for transport from one of the reels to the other. The housing is formed with a mouth (12) through which a transducer (61) can gain access to the recording tape (T) to record or reproduce signals on or from the recording tape (T). The reels (4, 5) in the first relative position conform to a first arrangement of a drive for driving the reels (4, 5) in rotation and afford a predetermined amount of space for accommodating the transducer (61) within the housing (1) for access to the recording tape (T) and in the second relative position correspond to a second arrangement of a drive for driving the reels (4, 5) in rotation and afford an additional amount of space for accommodating the transducer (61) within the housing (1) for access to the recording tape (T). The translation of the reels has a component parallel to a left-to-right direction of the housing as well as a front-to-rear direction of the housing, so that the reels in the second position are displaced towards the rear corners of the tape cassette.
    • 磁带盒包括一个壳体(1)和一对安装成用于在壳体(1)中旋转和平移的卷轴(4,5),使得卷轴可以呈现第一和第二相对位置中的任一个。 记录带(T)卷绕在卷轴(4,5)上并在其间延伸以从卷轴之一传送到另一卷轴。 壳体形成有口(12),换能器(61)可以通过该口(12)访问记录带(T)以在记录带(T)上记录或再现信号。 在第一相对位置的卷轴(4,5)符合用于驱动卷轴(4,5)旋转的驱动器的第一布置,并提供预定量的空间,用于将换能器(61)容纳在壳体(1)内 ),并且在第二相对位置对应于用于驱动卷轴(4,5)旋转的驱动器的第二布置,并提供用于容纳换能器(61)的额外量的空间 用于存取记录带(T)的外壳(1)。 卷轴的平移具有平行于壳体的左右方向的部件以及壳体的前后方向,使得第二位置的卷轴朝向 磁带盒
