摘要： A sliding shutter for a magnetic disk cartridge is disclosed which includes an engaging member positioned to contact a torsion spring in the cartridge during the process of fitting the shutter onto the cartridge. The engaging member acts to guide the spring to the proper position for engagement and has an angled face to facilitate the movement of the spring into engagement in a notch in the engaging member. This also reduces the rate of product rejects caused by springs which are mis-positioned during the assembly process.
摘要翻译：公开了一种用于磁盘盒的滑动快门，其包括在将快门安装到盒上的过程中定位成接触盒中的扭簧的接合构件。接合构件用于将弹簧引导到用于接合的适当位置，并且具有成角度的表面以便于弹簧移动到接合构件中的凹口中。这也降低了在组装过程中由错误定位的弹簧引起的产品拒收的速度。

摘要： A magnetic disk cartridge containing a floppy magnetic disk is provided with center core which has a groove where the vertical part of the core meets the flange upon which the disk is fastened by a double-sided adhesive ring. This groove can accommodate a portion of the adhesive ring which is positioned out of true. This ensures that such misalignment does not cause deformation of the disk and the deterioration in read/write performance with the disk. The groove also serves to prevent flange flashing from scraping fragments off the inside of the cartridge wall, and the possible harm such fragments cause if they stick to the disk.
摘要翻译：包含软磁盘的磁盘盒设置有具有凹槽的中心芯，其中芯的垂直部分与通过双面粘合环固定该盘的凸缘相接合。该凹槽可以容纳位于真实位置的粘合环的一部分。这确保了这种不对准不会导致盘的变形和盘的读/写性能的劣化。凹槽还用于防止法兰从墨盒壁内部刮掉碎片闪光，并且如果它们粘附在盘上，可能会造成伤害。

摘要： A magnetic recording disk cartridge comprises a magnetic recording disk accomodated for rotation in a casing. The magnetic recording disk is provided with a center core having a central opening into which a spindle of a magnetic recording/reproducing system is inserted to be drivingly engaged therewith. The center core comprises a core block provided with the central opening and a pair of slits formed in the wall portion of the core block defining the central opening and spaced from each other by a predetermined distance; and a plate spring which extends across the central opening and the opposite end portions of which are fitted into the slits and held therein so that the plate spring can be resiliently deformed in a direction radial to the magnetic recording disk. When the spindle is fitted into the central opening, the plate spring is pushed by the spindle to be resiliently deformed, and the outer pheripheral surface of the spindle is urged radially inwardly by the resiliency of the plate spring so that the rotational axis of the spindle coincides with the central axis of the magnetic recording disk.
摘要翻译：磁记录盘盒包括容纳在壳体中旋转的磁记录盘。磁记录盘设置有具有中心开口的中心芯，磁记录/再现系统的主轴插入其中以与其驱动接合。中心芯包括设置有中心开口的芯块和形成在芯块的壁部分中的一对狭缝，其限定中心开口并彼此间隔预定距离; 以及平板弹簧，其延伸穿过中心开口并且其相对的端部装配到狭缝中并保持在其中，使得板簧可以在与磁记录盘径向的方向上弹性变形。当主轴装配到中央开口中时，板簧被主轴推动以弹性变形，并且主轴的外表面由于弹簧的弹性被径向向内推动，使得主轴的旋转轴线与磁记录盘的中心轴重合。

摘要： A magnetic tape cassette includes a slider fitted slidably along a bottom of a cassette case, as well as resiliently locking pieces formed in the bottom of the cassette case along the bottom in a cantilevered fashion and each having a head at a free end thereof for fitting in an engaging hole in the slider so as to retain the slider. Each of the resiliently locking pieces has a compression coil spring provided between the head 12a and an upper half 11a of the cassette case to maintain a resilient force for the head in a thickness-wise direction of the cassette. When the head is pushed into the cassette case by more than a predetermined amount, coils of the compression coil spring are set in a state of close contact with each other in a compressing direction of the spring so as to support the head from an inward direction of the cassette and positionally restrict the displacement of the resiliently locking piece in the inward direction of the cassette.
摘要翻译：磁带盒包括沿着盒壳底部可滑动地配合的滑块，以及以悬臂方式沿着底部形成在盒壳底部的弹性锁定件，并且每个在其自由端具有用于装配的头部在滑块中的接合孔中，以便保持滑块。弹性锁定片中的每一个具有设置在头部12a和盒壳体的上半部11a之间的压缩螺旋弹簧，以在盒的厚度方向保持头部的弹性力。当头部被推入盒壳体中超过预定量时，压缩螺旋弹簧的线圈被设定为在弹簧的压缩方向上彼此紧密接触的状态，以便从向内的方向并且位置地限制弹性锁定件在盒的向内方向上的位移。
