Abstract: A magnetic tape cassette (1) having a cassette casing (2) formed of upper and lower halves (3, 4), reel hubs (7) accommodated within the cassette casing (2) and around which a magnetic tape (6) is wound, a locking member (13) for locking rotation of the reel hubs (7), a tape loading pocket portion (10) formed on one of the upper and lower halves (3, 4) a slider (17) for opening and closing reel shaft insertion apertures (5), a slider lock member (18) for locking the slider (17) at an open position and at a closed position, limiter pins (20) for preventing the slider lock member (18) from being deformed more than is necessary, and a pair of left and right hub lock springs (24) for spring-biasing the hub lock member (13) in the direction in which the reel hubs (7) are locked.

Abstract: A magnetictape cassette (1) having an upper part (3) and a lower part (4) combined during assembly to form a unitary housing (2), a front lid (12) that can be moved between an open position, and a closed postion, a pair of reel hubs (7) rotatably mounted within the cassette housing (2) for winding a tape (6) thereon, and a hub lock member (13) for locking the pair of reel hubs (7), includes a structure to temporarily secure the hub lock member (13) to the upper part (3) in a range outside a normal movable range of the hub lock member (13). This structure is formed as a cut-away portion (18) having a predetermined width in its movable direction formed on the hub lock member (13) and a stopper element (19) formed on the lower part (4) in association with the cut-away portion (18), so that an edge of the cut-away portion (18) comes in contact with the stopper element (19) to prevent the hub lock member (13) from being once again secured to the upper part (3) once the housing (2) is assembled.

Abstract: A tape cassette comprises a cassette housing composed of an upper cassette part and a lower cassette part and which accommodates therein a pair of tape hubs around which a magnetic tape is wound, a slider slidably provided on the cassette housing so as to open and close a lower surface opening portion of the cassette housing, a slider lock portion provided on the lower cassette part to lock the slider at a predetermined position, an engagement aperture bored through the slider and which is engaged with the slider lock portion, and an inclined portion having a configuration tapered toward the cassette housing being formed on one end face of the engagement aperture bored through the slider which opposes the top of the slider lock portion of the lower cassette part. Further, a tape cassette comprises a cassette housing composed of an upper cassette part and a lower cassette part and which accommodates therein a pair of tape hubs around which a magnetic tape is wound, a slider slidably provided on the cassette housing so as to open and close a lower surface opening portion of the cassette housing, a slider lock portion provided on the lower cassette part to lock the slider at a predetermined position, an engagement aperture bored through the slider and which is engaged with the slider lock portion, a protruded pin projected from the upper cassette part in association with the slider lock portion, and a slider lock spring inserted into the protruded pin and interposed between the slider lock portion and the upper cassette part, the slider lock portion being spring-biased by the slider lock spring in the direction in which the slider lock portion is fitted into the engagement aperture, wherein at least one end portion of the slider lock spring is bent toward the inside of a coil winding portion to form a pin supporting portion which is wound around the protruded pin.
