    • A cartridge including a fixed hub (14) having a central opening (16) and a slot (17) communicating with the opening (16), and an endless length of magnetic tape (22) having a major portion coiled about the hub (14) and a minor portion extending from the innermost wrap of the coil (26), through the slot (17) and around the side surface of the coil (26) to the coil's outermost wrap. Means on the housing (12) defining a tape path for the minor tape portion include a spring (72) biased movable guide pin (34) that provides a desired low, predetermined tension in the outermost wrap of the coil (26), which in turn produces a relatively high, generally uniform tension in tape (22) being pulled from the coil (26) through the slot (17). A portion (13) of the hub (14) can be moved radially to adjust the length of the minor tape portion, and a lock assembly (15) is provided for restricting movement of tape (22) in the coil (26) during shipping.
    • 包括具有中心开口(16)和与开口(16)连通的槽(17)的固定轮毂(14)的盒,以及环形长度的磁带(22),其具有围绕轮毂(14)卷绕的主要部分 )和从线圈(26)的最内部包裹线延伸通过槽(17)并且围绕线圈(26)的侧表面延伸到线圈的最外侧包裹物的次要部分。 限定用于次要带部分的带路径的壳体(12)上的装置包括弹簧(72),偏压的可移动引导销(34),其在线圈(26)的最外包层中提供期望的低的预定张力, 在从线圈(26)通过狭槽(17)拉出的带子(22)中产生相对较高的,通常均匀的张力。 轮毂(14)的一部分(13)可以径向地移动以调整次要带部分的长度,并且提供锁定组件(15),用于在运送期间限制带(22)在线圈(26)中的运动 。

    • A tape cassette device which comprises a cassette case (11) in which a stationary reel (15) with a tape guide path (17) is housed, and an endless tape (16) wound on the outer circumference of said stationary reel (15), the innermost part of the tape being drawn out along said guide path to the inside of said stationary reel to be wound on the outer circumference of said stationary reel. Said case has a bottom plate (19) having a scanning head and a tape drive mechanism inserting opening located at the inside of said stationary reel.
      A pair of sliders (31,33) are disposed inside said cassette case, which are displaceable between a lower position where it is located at the side of said bottom plate (19) for closing said opening and an upper position where it is located away from said bottom plate (19) for opening said opening.
      The bottom plate (19) has a plurality of roller inserting openings (21a, 21b, 21c) formed along the outer circumference of said stationary reel (15). Said openings may be closed by a rotatably mounted blind (24).
    • 一种盒式磁带装置,其特征在于,包括盒体(11),容纳带导向路径(17)的固定卷轴(15)和卷绕在所述固定卷轴(15)的外周的环形带(16) 磁带的最内部沿着所述引导路径被拉出到所述固定卷轴的内部,以卷绕在所述固定卷轴的外圆周上。 所述壳体具有位于所述固定卷轴内部的扫描头和带驱动机构插入孔的底板(19)。 一对滑块(31,33)设置在所述盒壳体的内部,所述滑块可位于位于所述底板(19)侧面的下部位置,用于封闭所述开口和位于其之间的上部位置 从所述底板(19)打开所述开口。 底板(19)具有沿着所述固定卷轴(15)的外周形成的多个辊插入口(21a,21b,21c)。 所述开口可以由可旋转地安装的百叶窗(24)封闭。
