The cassette tape recorder for the four common types of cassettes according to German Industrial Standards DIN 32 715 T, 32 715 W, and the so-called micro-cassette as well as the mini-M-cassette comprises three sound head carriers (10, 20, 30) adapted to be moved selectively into operating position. Furthermore, the spacing between winding shafts (2,2') is adjustable by a movable cam disc (17). This adjustment is taken care of by cam disc engaging fixtures (23, 33) at the movable sound head carriers (20 and 30, respectively) and by a spring (18) holding the cam disc (17) in an inoperative position against a stop. Likewise provided are adjustable winding heads (3,3') causing different engagement members (4,6) to become effective for the winding drive, the adjustment of the winding heads (3,3') also being effected upon moving of the sound head carriers (10,20,30). Scanning members serve to scan a geometric dimension of the cassette and based on that scanning the spacing of the winding shafts (2,2'), the position of one of the sound heads (14,35,60) and, if desired, adjustment of the winding heads (3,3') and their engagement members (4,6) are determined.
A cassette tape recorder operable for use with a plurality of cassettes having respective different geometric dimensions and respective different spacing of cassette winding drums, comprising two winding shafts (2, 2') movably disposed at variable spacing positions and each including adjustable engaging fixtures for engaging different types of winding drums of the cassettes, further comprising at least one electromagnetic sound head disposed on a carrier which is movably positionable with respect to the winding shafts, characterized in that the at last one sound head (14, 35, 60) is movable into either of two predetermined limit positions, in that a scanning member (102, 103, 118-122;
A cassette tape recorder operable for use with a plurality of types of cassettes each having respective different geometric dimensions and respective different spacings of cassette winding drums and respective different dimensions of winding mandrels and respective different sound head positioning requirements;
