摘要： A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. The reel has a reel hub in the form of a cylindrical member which has a bottom wall and is provided with an opening and a stopper gear formed on the bottom wall. A brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear is brought into engagement with the stopper gear to prevent rotation of the reel and a retracted position where the brake gear is disengaged from the stopper gear to permit rotation of the reel. The brake member is normally urged toward the operative position and moved to the retracted position by a pusher member of a tape drive system which acts on the brake member through the opening in the reel hub when the magnetic tape cartridge is loaded in the tape drive system. A continuous wall portion is erected around the opening in the reel hub, and the brake member includes a horizontal portion and a continuous skirt portion which extends downward from the horizontal portion and is in contact with the continuous wall portion of the reel hub to close the opening together with the horizontal portion. The brake member is moved between the operative position and the retracted position with the skirt portion kept in cotact with the continuous wall portion of the reel hub.
摘要翻译：一种磁带盒包括一个盒壳和一个容纳在盒壳内用于转动的单个卷轴。卷轴具有呈圆柱形构件形式的卷轴毂，其具有底壁并且设置有开口和形成在底壁上的止动齿轮。制动部件设置有制动齿轮，并且可在制动齿轮与制动齿轮接合以防止卷轴旋转的操作位置和制动齿轮从制动器脱离的缩回位置之间上下移动齿轮以允许卷筒的旋转。制动部件通常被推向操作位置，并通过磁带驱动系统的推动器部件移动到缩回位置，当磁带盒装入磁带驱动系统时，磁带驱动系统的推动器部件通过卷轴毂中的开口作用在制动部件上。连续的壁部分围绕卷轴毂的开口竖立，并且制动部件包括水平部分和从水平部分向下延伸并且与卷轴毂的连续壁部分接触以闭合与水平部分一起打开。制动构件在工作位置和缩回位置之间移动，其中裙部保持与卷轴毂的连续壁部分共同作用。
