摘要: A magnetic-tape-cassette apparatus includes a loading mechanism with a cassette holder (321, 348) which is adapted to lift the magnetic-tape cassette (200) into an ejection position, in which the cassette (200) is inserted and ejected, and to lower the magnetic-tape cassette (200) onto a cassette support (331) in a play position, in which the reel hubs (200e) are engaged by winding spindles (330). The cassette holder (321,348) has a cross-sectionally U-shaped part (321, 348) with two facing holder plates (323, 324, 348a, 348b) and a transverse holder wall (328, 348c) interconnecting the holder plates, the cassette holder (321, 348) being pivotable about a spindle (325) in such a manner that in the ejection position one holder plate (323, 348a) and in the play position the other holder plate (324, 348b) extend substantially parallel to the cassette support (231). In the area of the transverse holder wall (322, 348c) there is provided a supporting ridge (327, 349 a, 354), on which the cassette (200) is supported in the ejection position and is movable while being supported, to lower the cassette (200) into the play position the supporting ridge (327, 348a, 354) is movable away from the cassette (200) to allow the rear wall (200c) of the cassette to be lowered.
