Abstract: The cassette half molding method molds one of upper and lower halves of the magnetic tape cassette by injection molding with an injection mold in which a gas vent pin for smoothing a flow of molten resin to be introduced in the cavity for molding a transparent or semitransparent window portion provided in the upper half. The cassette half is molded by this molding method. The magnetic tape cassette has a friction sheet interposed either between a pair of take-up hubs and the upper half, or between the pair of take-up hubs and the lower half, or both, and the friction sheet is made of polyethylene-based resin and has a surface electric resistance value in the range of 1×107 &OHgr; to 1×1010 &OHgr;. The magnetic tape cassette has a rib for reducing a resistance when the roller of the detecting member passes through which is provided at a position corresponding to a recess and on a side of the front lid in the top surface of the body case.

Abstract: A magnetic tape cassette, such as a high performance video cassette, having a greatly improved dust-proofing function. In a first embodiment, operating portions of brake members which engage a brake release lever which is inserted into the cassette at the time of recording or reproduction to release the braking system of the cassette are formed in an inverted cup shape so as to close the hole through which the brake release lever is inserted and to contain the end of the brake release lever when inserted into the hole. In a second embodiment, separate engagement and abutment portions are provided for each brake portion so as to prevent inadvertent opening of the hole if the tape reels are moved during storage. In a third embodiment, the dust-blocking member takes the form of a slitted flexible sheet member covering the hole when the cassette is not in use.

Abstract: 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.

Abstract: A magnetic tape cassette of two half cases. A locking member is slidable backwards to lock the hubs holding the tape. The locking member is biased by a spring fixed to a protrusion at the front of one of the half cases. Backward facing legs of the springs slidably engage a lateral recess in the locking member to bias it backwards against the hubs.
