    • A magnetic tape cassette in which unwinding of the tape is prevented independent of the type of hub utilized. Each of the two hubs of the tape cassette includes a first cylindrical wall in which is formed a shaft hole adapted to receive a rotary drive shaft of the tape unit with which the cassette is used. A second cylindrical wall is formed coaxially with the first cylindrical wall and the second cylindrical wall has an engaging groove formed in an interior surface thereof. Also provided is a locking device including a crosswise locking member provided on the bottom of the lower half of the cassette case between the two hubs. The locking member includes a straight bar and arm with locking pawls substantially in the form of a cross and a spring member. The locking member is movable back and forth in the longitudinal direction of the straight bar and urged in one direction by the spring so that rotation in at least one direction of the hubs is stopped by engagement of the locking pawls with the engaging grooves.
    • 独立于所使用的轮毂的类型,防止带退绕的磁带盒。 磁带盒的两个轮毂中的每一个包括第一圆柱形壁,其中形成有轴孔,该轴孔适于容纳使用该盒的带单元的旋转驱动轴。 第二圆柱形壁与第一圆柱形壁同轴地形成,并且第二圆柱形壁在其内表面中形成有接合槽。 还提供了一种锁定装置,其包括设置在两个轮毂之间的盒壳体的下半部的底部上的横向锁定构件。 锁定构件包括具有大致呈十字形和弹簧构件形式的锁定爪的直杆和臂。 锁定构件可以在直杆的纵向方向上前后移动并且通过弹簧沿一个方向被推动,使得通过锁定爪与接合槽的接合来阻止轮毂的至少一个方向上的旋转。
