摘要： A tape reel for a tape cassette wherein a pair of such reels are contained, comprising an upper flange and a hub which consists of a drum formed integrally with (formed in one piece with, or solidly joined to) a lower flange. The drum comprises an outer cylindrical part on which a tape is wound and an inner cylindrical part which permits the insertion of a driving shaft of a recording-reproducing device for the tape cassette. The inner cylindrical part has projections adapted to engage with the driving shaft, each said projection having a groove formed on the back side for thickness reduction, and the inner cylindrical part and inner ends and both side walls of the projections all have the same thickness. A plurality of connecting ribs are provided joining the outer and inner cylindrical parts of the drum, and extensions are formed outwardly on the inner cylindrical part, on both shoulder portions close to each said connecting rib. Alternatively, a plurality of ribs are formed along the inner circumference of the outer cylindrical part, extending from the outer cylindrical part toward, but short of, the inner cylindrical part.

摘要： A tape cassette is provided with a lock member of a covering member integrally connected with a spring member having high durability and strength as well as improved workability at assembling. The tape cassette includes a covering member rotatably mounted to the housing to cover the tape member placed at a front of the housing, and a lock member provided inside the housing to lock the covering member in a closed state. The lock member is rotated together with the main body and is provided with rotation shafts pivotally supported in the housing, an engagement projection rotating around the axis between the locked position engaging with the covering member and the locked position not engaging with the covering member, biasing members for biasing the engagement projection toward the locked position, and an unlock member for shifting the engagement projection toward an unlocked position. The biasing member is integrally connected with the main body at a remote position from the engagement projection and the unlock member.

摘要： When a guide wall formed in the lower casing of a tape cassette housing for guiding a brake release member is extended upward into the upper casing, the corresponding part of the upper casing must be cut off to provide a recess. The recess, located in the central part of the upper casing, reduces the structural strength of the upper casing. Also there are problems of deformation of the cassette wall parts subject to the urging of the spring member and development of a gap between the mating edges of the upper and lower casings during storage at elevated temperature. The present invention is directed to the solution of the problems.In a tape cassette which includes a housing comprised of upper and lower casings, a pair of tape reels turnably held in the housing, and a brake mechanism comprising reel brake members and a brake release member all of which are located in the front part of the housing and between the pair of tape reels, in an arrangement such that, when the cassette is not in use, the brake members are urged by a spring member in directions where they are in mesh with serrated flange peripheries of the reels and, when the cassette is used, the release member is forced upward against the spring force by a brake release pin and the brake members cooperatively swing out of mesh with the serrated flange peripheries of the reels, setting the tape reels free to turn; a guide wall for guiding the release member for upward and downward movement is formed in one piece with the lower casing, with the upper part of the guide wall being overlapped with a corresponding part of the upper casing. A solid joint part for securing the upper and lower casings together is provided in the vicinity of the region where the release lever moves upward and downward along the front wall.
摘要翻译：当形成在用于引导制动器释放构件的带盒壳体的下壳体中的引导壁向上延伸到上壳体中时，必须切断上壳体的相应部分以提供凹部。位于上壳体中心部分的凹槽减小了上壳体的结构强度。此外，存在受到弹簧构件的推动的盒壁部件的变形和在升高的温度下储存期间在上部和下部壳体的配合边缘之间的间隙的展开的问题。本发明的目的在于解决这些问题。在包括由上下壳体组成的壳体的磁带盒中，可转动地保持在壳体中的一对磁带盘，以及包括卷轴制动部件和制动器释放部件的制动机构，所述制动机构全都位于壳体和一对磁带盘之间的布置，使得当盒不使用时，制动构件在与卷轴的锯齿形凸缘外周啮合的方向上被弹簧构件推动，并且当使用盒式磁带，释放构件通过制动释放销而抵抗弹簧力而被向上推动，并且制动构件与卷轴的锯齿状凸缘外围配合摆动离开网格，使磁带盘自由旋转; 用于引导释放构件向上和向下运动的引导壁与下壳体一体地形成，导向壁的上部与上壳体的对应部分重叠。在该释放杆沿着前壁上下移动的区域附近设置有将上下壳体固定在一起的实心接合部。

摘要： In a tape cassette, a reel brake member has an opening hole portion for insertion of a brake release member on a device side, and a guide recessed portion for guiding the brake release member is formed in a central portion of an abutment side wall portion of the brake release member in the opening hole portion. This guide recessed portion is formed in the abutment side wall portion of the brake release member in a vertical direction in a central portion of the opening hole portion, and an internal surface of the guide recessed portion is formed into a U-shaped groove having a curved surface. Arms are provided on sides of a main body of a reel brake member via hinge portions, and a brake pawl is provided at a distal end of the respective brake pawls. An opening hole is formed for insertion of a brake release operation member provided on a device side. In addition, upper surface portion and lower surface portion are provided which are adapted to abut with and slide over internal surfaces of upper and lower cases. Recessed portions are provided on the upper surface portion on both sides of a front side at positions corresponding to outer circumferential edges of the tape reels, and a butt recessed portion is provided on a front side of the lower surface portion so as to correspond to holding ribs provided along tape reel receiving areas on a front side of a reel brake sliding area.

摘要： A tape cassette capable of satisfactorily exhibiting a stable braking function sufficient to prevent tape looseness during non-use of the tape cassette. A release lever is vertically movably arranged in a casing and downwardly forced by a coiled spring. Reel brakes each have a operating cam section against the release lever to be operatively associated therewith. Thus, a release pin provided on a side of a deck for driving or operating the tape cassette is upwardly abutted against a lower surface of the release lever.

摘要： A tape cassette comprising a housing made up of upper and lower casings, a pair of reels around which a tape is wound and contained altogether in the housing, and a pair of cylindrical resin tape guides having a height greater than the width of the tape, said tape guides being securely fitted to corresponding tape guide posts also having a height greater than the width of the tape and provided in the lower casing. Each tape guide post has a press-fit rib formed in one piece with it on the side where the tape does not come in contact with the tape guide on it. The rib has a vertical height greater than half that of the tape guide and serves to make the dimensions of the tape guide post surface on the tape-contacting side greater than the inside diameter of the tape guide before being press-fitted.
