摘要： A resilient, durable reel-locking member is provided in a magnetic tape cassette including a cassette case, a pair of reels rotatable in the cassette case to wind a magnetic tape, each of the reels including a flange and a plurality of teeth formed on a peripheral portion of the flange. The resilient, durable reel-locking member includes a slide body slidable between the reels in a front-rear direction of the cassette case, a pushing member pushing the slide body in the front-rear direction of the cassette case, a pair of cantilevered, arcuate expansions formed on opposite sides of the slide body, each of the expansions facing a respective adjacent one of the reels and extending in a direction normal to the front-rear direction of the cassette case, and a pair of claws, each of the claws projecting from a respective one of the expansions and being engagable with the teeth of the respective adjacent one of the reels. The magnetic tape cassette is having a reel-locking member with reduced susceptibility to engagement fatigue. Engagement fatigue is a frequent cause of failure and/or breakage of the reel-locking members of the conventional magnetic tape cassettes.
摘要翻译：一种具有弹性，耐用的卷线锁定构件设置在磁带盒中，该磁带盒包括盒壳体，一对可在盒壳体中旋转以卷绕磁带的卷盘，每个卷轴包括凸缘和形成在其上的多个齿凸缘的周边部分。弹性耐用的卷线锁定部件具有滑动体，该滑动体能够沿着盒壳体的前后方向在卷轴之间滑动，推动部件沿着盒壳体的前后方向推动滑动体，一对悬臂，形成在滑动体的相对侧上的弓形膨胀，每个膨胀面向彼此相邻的一个卷轴并且沿着垂直于盒壳体的前后方向的方向延伸，以及一对爪，每个爪从相应的一个扩展部突出并且可与相应的相邻的一个卷轴的齿接合。磁带盒具有对接合疲劳的敏感性降低的卷轴锁定构件。啮合疲劳是常规磁带盒的卷轴锁定部件的故障和/或破损的常见原因。

摘要： A magnetic tape cassette comprises an approximately rectangular bottom wall provided with an opening, into which a spindle is to be inserted, a side wall extending along the periphery of the bottom wall, and a structural part formed integrally with the bottom wall at a corner of the bottom wall and in proximity to the side wall. The magnetic tape cassette is of a thin-walled type, constituted of a resin, and integrally molded by feeding the resin from a position corresponding to the vicinity of a center point of the bottom wall into a mold. The bottom wall is provided with a flow path-like, thick-walled portion extending along a direction heading from the position in the bottom wall corresponding to the position, from which the resin is fed into the mold, approximately towards the structural part.
摘要翻译：一个磁带盒包括大致矩形的底壁，该底壁设置有一个主轴要被插入的开口，一个沿着底壁的周边延伸的侧壁，以及一个结构部分，底壁并靠近侧壁。该磁带盒是由树脂构成的薄壁型，并通过将树脂从与底壁的中心点附近相对应的位置进入模具而整体成型。底壁设置有沿着从底壁中的位置方向延伸的流动路径状的厚壁部分，该位置对应于树脂被输送到模具中的大致朝向结构部件的位置。

摘要： An improvement of a photographic film roll composed of a spool which has a spool core having a slit therein and a flange at both ends of the spool core and a photographic 120-size film which is placed and fixed on a continuous light-shielding backing paper in which one end of the backing paper is inserted into the slit of the spool and other portion of the backing paper is wound on the spool to form multiple convolutions, resides in that the backing paper has at the center in its longitudinal direction a width less than the distance between the two flanges measured at the position of ½ of height of the flanges and has two wide areas of at least 10 cm long one of which is within 50 cm area measured from its one end and another of which is within 50 cm area measured from its another end, the width of each wide area being larger than the distance between the two flanges measured at the tops of the flanges.
摘要翻译：改进由卷轴构成的照相胶片卷，该卷轴具有其中具有狭缝的卷轴芯和卷轴芯的两端的凸缘和照相120尺寸的胶片，其被放置和固定在连续的遮光背衬纸上其中背纸的一端插入卷轴的狭缝中，并且背纸的其他部分缠绕在卷轴上以形成多个卷绕，其特征在于，背纸在其纵向方向上的中心具有较小的宽度比在法兰高度的1/2的位置测量的两个凸缘之间的距离，并且具有至少10cm长的两个宽的区域，其中一个在其一端测量的50cm范围内，另一个在50cm以内从其另一端测量的面积，每个广域的宽度大于在凸缘的顶部处测量的两个凸缘之间的距离。

摘要： In a magnetic tape cassette including a cassette case, a pair of reels rotatable in the cassette case to wind a magnetic tape, each of the reels including a flange and a plurality of teeth formed at a peripheral portion of the flange., and a lock member engaging the flange for preventing the reels from rotating, the lock member further includes a slide body slidable between the reels in a front-rear direction of the cassette case, a pushing member pushing the slide body in the front-rear direction of the cassette case, a pair of expansions formed on opposite sides of the slide body facing the reels, each of the expansions expanding in a direction normal to the front-rear direction of the cassette case, and a pair of claws projecting from the respective expansions and being engagable to the teeth. The magnetic tape cassette is less susceptible to engagement fatigue of the lock member claws than conventional magnetic tape constructions, thereby ensuring more reliable reel-locking and greater longevity of the cassette.
