    Abstract: In a cassette for use in a magnetic recording and/or reproducing apparatus, a housing contains rotatable reels on which a resiliently flexible tape is wound and the housing has an access opening extending along a side thereof through which the tape can be withdrawn for the recording and reproducing of signals thereon, guide members within the housing adjacent the opposite ends of the opening direct the tape between the reels in a path including a run extending along the opening and path portions extending from adjacent the ends of such opening tangentially to the outer turns of said tape wound on the respective reels, and at least one tape shifting member acts against a face of said tape in a respective one of the path portions. Each tape shifting member is mounted for movement in a course spaced from the adjacent guide member and is resiliently urged to a normal position in which the tape shifting member produces a bend in the related path portion between the respective guide member and reel so that turning of that reel in the tape unwinding direction enlarges the tape bend due to the resilient flexibility of the tape and transmission of the resulting slack in the tape to the tape run across the access opening is avoided. The tape shifting member is deflected from its normal position by the tape in response to a substantial tension in the latter for removing the bend from the respective path portion.

    Abstract translation: 在用于磁记录和/或再现装置的盒中，壳体包含可旋转的卷轴，弹性柔性带被卷绕在该卷轴上，并且壳体具有沿其一侧延伸的进入开口，通过该导向，可以将带取出用于记录 并且在其中再现信号，所述壳体内邻近所述开口的相对端的导向构件将所述带在所述卷轴之间引导，所述引导构件沿包括沿着所述开口延伸的行程的路径以及从所述开口的相邻端部相切地延伸到所述外圈 所述带缠绕在相应的卷轴上，并且至少一个带移位构件在相应的一个路径部分中作用在所述带的表面上。 每个带移动构件安装成在与相邻引导构件间隔开的过程中移动，并且被弹性地推动到正常位置，在正常位置，带移位构件在相应的引导构件和卷轴之间的相关路径部分中产生弯曲， 磁带退绕方向上的卷轴由于带的弹性挠性而增加了带弯曲，并且避免了所产生的带中的松弛传播到穿过进入开口的带子。 带移动构件响应于后者中的实质张力而被带从其正常位置偏转，以从相应的路径部分移除弯曲部。

    Abstract: A tape casette arrangement includes structures formed integrally with the casssette halves or simply fitted into the light transmission apertures. Specific embodiments of the invention include light polarizing elements which are fitted into apertures formed in the sides of the cassette, corrugations on the interior of the cassette proximate the apertures, and shielding walls which are located to block light and in particular that light which tends to enter through a large window provided in the upper surface of the cassette and through which the status of the tape is visible.

    Abstract: A tape cassette for video or audio units which consists of a housing having an upper half and a lower half, the upper half being composed mainly of an opaque material, the upper half having a transparent window portion on the upper wall thereof. A cover portion is laminated to the upper half, the cover portion being composed of a transparent material, the window portion consisting of a single layer of the transparent material, with an additional portion of the upper half formed of a double layer of the transparent material and the opaque material.

    Abstract: A reel brake device 100 of a magnetic tape cassette has a pair of braking pawls 105,106 for a supply reel and a take-up reel. The braking pawls are formed to allow resilient deformation in order to absorb kinematic energy exerted on the braking pawls by the tape reels as the reels are subject to rotational torque or lateral force, such that braking engagement can be maintained even when vibration exerting rotational force to the tape reels is applied. The pawls are resilently deformable at areas 107,108 of less thickness along their lengths and at their zones of joining 109,110 to the brake assembly. Means 119,120,120 (and 136,137 in Fig. 8) are provided to limit the extent of action of the pawls.
