摘要： The disk tray of a disk casing is provided with an end portion which has an upper surface facing upward flush with a principal surface of the upper lid when the casing is closed, and an end portion of a lower index card inserted in a space between the disk tray and the lower lid is bent upward along an inner surface of the end wall of the lower lid on the side of the axis. The end wall of the lower lid on the side of the axis is formed to be flush with the upper surface of the end portion of the disk tray so that the upper end of the lower index card is inserted into the slit by way of which the upper edge portion is opposed to an outer edge portion of the end portion of the disk tray.

摘要： A magnetic tape cartridge is provided, in which the mating of the lower half and the upper half can be easily performed and which is applicable to automated assembly, when the magnetic tape cartridge having a sliding door is assembled. The rib projects from the upper section of the first guide wall in the direction of the opposite second guide wall. On the other hand, the groove, which faces the rib, is carved on the inner side surface of the sliding door. The rib engages with the groove, thereby restricting the vertical displacement of the sliding door. Also, the engagement of the rib and the groove guides the sliding door in the guide channel freely.

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 contact with the continuous wall portion of the reel hub.
摘要翻译：磁带盒包括盒壳体和容纳在盒壳体中用于旋转的单个卷轴。卷轴具有圆筒形构件的形式的卷轴毂，其具有底壁，并且设置有形成在底壁上的开口和止动齿轮。制动构件设置有制动器齿轮，并且可以在制动齿轮与止动齿轮啮合的操作位置之间上下移动，以防止卷轴旋转和制动器与止动器脱离的缩回位置齿轮以允许卷轴旋转。制动构件通常被推向操作位置，并且当磁带驱动系统的推动构件通过卷带盘毂中的开口作用在制动构件上时被推动到缩回位置，当磁带盒装入磁带驱动系统。连续的壁部分围绕卷轴轮毂中的开口竖立，并且制动部件包括从水平部分向下延伸并且与卷轴轮毂的连续壁部分接触的水平部分和连续的裙部，以闭合与水平部分一起打开。制动构件在操作位置和缩回位置之间移动，裙部保持与卷轴毂的连续壁部分接触。

摘要： Disclosed herein is a magnetic tape cartridge comprising a single reel with magnetic tape wound thereon, a cartridge case for rotatably housing the single reel, a leader pin having a tape clamp portion on which the magnetic tape is wound, and a clamp member with a C cross section that has an axial slit. The leader pin is affixed to a leading end of the magnetic tape by elastically fitting the clamp member onto the tape clamp portion of the leader pin. A sheet member for enhancing a coefficient of friction is interposed at least between the magnetic tape and the tape clamp portion.
