    摘要: A pad which is to be provided in the interior of a videotape cassette according to this invention is in the form of a hollow cylinder. When fitted in place in the interior of a videotape cassette, the cylindrical pad is yieldingly deformed to produce a resilient force, thereby pushing a videotape against an associated guide stud. Because of the cylindrical shape, the pad requires no large space to mount, and accordingly a videotape cassette can be substantially reduced in size. The cylindrical pad need only be pushed into place in the interior of a cassette housing, and this easy mounting is advantageous to the mass-production of videotape cassettes.

    摘要: A miniturized video magnetic tape cassette of the type in which a magnetic tape wound on a pair of hubs in the hollow interior of a cassette casing is guided to run across a front opening formed in the casing along a rotatable front cover and in which the tape can be pulled out of the front opening in the cassette. The tape cassette includes locking mechanism having a supporting shaft fixed to a bottom wall of the casing and a hub rotatably mounted on the supporting shaft. An L-shaped locking lever extends from the hub and a first stop extends from the hub in a direction opposite that of the locking lever. A coil spring has a coil portion disposed around an upper portion of a hub in which a slit is formed. A first end of the coil spring is inserted into the slit while the second end abuts against an inner surface of a side wall of the casing.

    摘要: A magnetic tape cassette storage case having a casing made up of a pocket for receiving the rear half of a magnetic tape cassette and a broad wall obtained by extending one wall of the pocket. A first cover, swingably connected to the pocket, has a first recess formed in its inner surface. A second cover, swingably connected to the broad wall, has a second recess formed in its inner surface. The first and second recesses receive the cassette's thicker portion in combination when the case is closed by the first and second cover. With the inventive case, the space required for storing the cases is smaller than that required for storing the same number of conventional ones.

    摘要: A miniature video magnetic tape cassette which is easy to assemble. An opening is formed in a front part of a cassette body which is covered by a guard panel, with the guard panel being swingably supported on the cassette body by shafts protruding from an inner surface of the side walls of the guard panel fitted into openings in the cassette body. A coil spring is supported on each supporting shaft with one end of each spring engaged with the guard panel to urge the guard panel toward the closed position of the opening. The other end of each coil spring is held by a locking structure provided on an inner surface adjacent to side wall of the upper half of the cassette body. The locking structure may be a locking shaft with the other end of the coil spring engaged with the locking shaft. Otherwise, the locking structure can be formed by a gap between the side wall of the upper half of the cassette and a supporting side wall inwardly thereof, in which case the other end of the coil spring is inserted into the gap and fixedly held therein with a block fitted in the gap.

    摘要: A transfer film comprising a base film and a releasant layer, an ink layer and an adhesive layer laminated on the base film in this order is inserted into a cavity of an injection mold, and injection molding material is injected into the cavity. After the molded article is removed from the mold, the base film is peeled off and the ink layer is transferred to the surface of the molded article. The injection mold has a coring pin for forming an opening in the molded article and the contact surface of the coring pin to be brought into contact with the adhesive layer of the transfer film has poor adhesion to the adhesive layer so that the bond strength between the contact surface of the coring pin and the adhesive layer is lower than those between the ink layer and the releasant layer and between the releasant layer and the base film.
