    Abstract: A tape cassette for a magnetic recording and/or reproducing apparatus has a housing formed with an opening through which the tape can be withdrawn from the cassette housing for the recording or reproducing of signals thereon, as by one or more rotary magnetic heads, and a lid is provided to normally close the housing opening when the cassette is not in use and thereby protect the tape from damage thereto. The cassette housing is provided with guides thereon extending at right angles to each other, for example, parallel to the relatively long and short sides of the cassette housing when the latter is rectangular, for the purpose of guiding the cassette into a holder therefor in either of the directions parallel to the long and short sides, respectively, of the housing. A latch mechanism is provided for locking the lid in its closed position, and such latch mechanism is releasable in response to the insertion of the cassette into a holder in either of the foregoing directions.

    Abstract: A tape cassette for a magnetic recording and/or reproducing apparatus has a housing formed with an opening through which the tape can be withdrawn from the cassette housing for the recording or reproducing of signals thereon, as by one or more rotary magnetic heads, and a lid is provided to normally close the housing opening when the cassette is not in use and thereby protect the tape from damage thereto. Locating members are provided on the cassette housing, preferably as integral extensions of the bottom wall, and extend through corresponding cutouts in the lid for engagement with respective abutments provided on the holder so as to accurately locate the cassette in respect to the holder while avoiding interference with the opening of the lid. The lid is provided with one or more interior partitions extending parallel to the front wall of the lid to define a channel which, in the closed position of the lid, accommodates the run of the tape extending across the opening of the cassette housing for preventing contact with such run of the tape through the cassette opening.

    Abstract: A tape recording and/or reproducing apparatus of the type having a tape guide drum with a circumferential slot through which at least one rotary transducer projects for recording and/or reproducing signals on a tape running against the periphery of the drum in a path which extends about at least a portion of such periphery; is provided with a tape guide assembly which includes a rigid guide, for example, constituted by an axially facing shoulder on the drum, engageable by the lower longitudinal edge of the tape for establishing the direction and location of the tape path, and spaced apart resilient guide elements extending radially on the top surface of the drum and being secured to the latter, at their inner ends, while the free end portions of the resilient guide elements project beyond the guide drum periphery and act yieldably against the upper longitudinal edge of the tape for holding the latter against the rigid guide with each resilient guide element flexing in a plane substantially at right angles to the tape path for accommodating variations and changes in the tape width. Further, a device is provided which acts simultaneously on all of the resilient guide elements for adjustably limiting the movements thereof in the direction toward the tape path.

    Abstract: In a tape cassette for use with a tape recording and/or reproducing apparatus having a rotatable reel drive device and which includes a cassette casing containing at least one rotatable tape-carrying reel provided with a hollow hub defining a socket having an opening at one end of the hub for receiving the reel drive device when the latter is inserted through an aperture in the casing registered with the socket; the socket is given a stepped configuration to have a reduced-diameter portion at the end remote from the socket opening and at least one axially elongated rib projects radially inward from the surface of the socket at a relatively larger-diameter portion of the socket, and the rotatable reel drive device is provided with an end portion closely engageable in the reduced-diameter portion of the socket for accurately locating the reel in respect to the axis of rotation of the reel drive device and with at least one projection extending radially beyond and spaced axially from such end portion of the reel drive device for reception in the relatively larger-diameter portion of the socket and driving engagement with the rib therein.
