摘要： A magnetic tape cassette in which protrusions made of low friction resin are formed on the inner walls of the upper and lower halves by a two-color molding method in such a manner that they are located in correspondence at least to the magnetic tape winding diameter so as to be in contact with the edges of the magnetic tape. The protrusions of low friction resin replace the friction sheets in the conventional magnetic tape cassette, whereby the number of components and the number of manufacturing steps are reduced, with the result that the manufacturing cost is also reduced.

摘要： A method for manufacturing the half body portions of a magnetic tape cassette or the like having an image transfer layer on its outer surface. An image transfer film is placed in a molding cavity, which film includes a base layer, a matting layer, and an image transfer layer. The function of the matting layer is to roughen the surface of the image transfer layer, while allowing easy subsequent peeling therefrom. A molten plastic is injected into the molding cavity against the image transfer layer. After the resulting product solidifies, the product is removed from the molding cavity, and the base layer and matting layer are peeled from the product, leaving the image transfer layer on an outside surface of the product.

摘要： A cassette accommodating case in which a tape cassette can be inserted in either a forward or backward orientation, and for preventing slackening of a magnetic tape, and to secure the tape cassette to eliminate play. Positioning projections having inclined surfaces are provided on each side of a casing section. When the casing section and a cover section are closed, the inclined surfaces abut against the ends of side projections on side surfaces of the tape cassette to push the tape cassette when the casing and cover sections are closed. A rotation-preventing projection of an accommodating case protrudes into a common area of the hubs when a cassette is loaded in the forward and backward orientations, and the projection includes two plate-like portions of different heights, disposed in parallel, and with a predetermined interval therebetween. A distal end of the long plate-like portion has a guiding inclined surface for correcting the positional offset of the hub by contacting its inner peripheral surface. The hub is retained by the two plate-like portions. Backward-pressing surfaces are provided in opposing corner portions of the case to secure the cassette tape within the case.

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： A magnetic tape cassette accommodating case has a cover member having a pocket for receiving one end portion of a magnetic tape cassette and a casing member having rotation stopper projections. At least (a) peripheral portions of the cover member and the casing member, which edge portions confront at least the thickened portion of the magnetic tape cassette, and (b) side wall portions of the cover member and the casing member, the side wall portions including the pivotably assembled portions, are molded with a resin, which is more slidable than the other portions of the cover member and the casing member. The other portions are molded with such a transparent resin as to allow the case to be seen through. A method for manufacturing such a magnetic tape cassette accommodating case utilizes a first slide core slidable in a direction of inserting a cassette, and a second slide core movable substantially orthogonal to the direction of moving the first slide core.

摘要： A magnetic tape cassette, particularly, a digital audio tape cassette, having an improved hub brake structure. The cassette includes upper and lower casing body half portions, and a window member secured to the upper casing body half portion. The window portion rotatably supports the pair of hubs on which a tape is wound. The hub brake includes a pair of lugs engageable with the hubs to prevent their rotation when the cassette is not in use. The hub brake is provided with a pair of engaging portions slidably received between respective support portions of the window member and the upper casing body half portion of slidably mounting the hub brake thereon. A spring urges the hub brake into engagement with the hubs.
