Abstract
A tape recording and/or playback apparatus having a cassette support positioned vertically by the magnetic head holder. The support is movable with the magnetic head unit in two transverse directions, one in which the heads are inserted in or retracted from the operative position, and the other in which the holder may be latched or unlatched so as to permit the support and magnetic head unit to move into the operating position.
Claims16
A tape recorder for use with a cassette on which magnetic tape is wound between two hubs, comprising:
- a housing section formed as a unitary mass of molded plastic material,
- a magnetic head unit comprising a magnetic head holder and at least one magnetic playback head,
- means for moving magnetic tape in a cassette which has been inserted into the recorder in a direction of tape transport past said at least one head,
- means for mounting the magnetic head unit to the housing section to be movable relative to the section in a first direction between a retracted position in which a cassette can be inserted into or removed from the recorder, and an operating position in which the magnetic head can operatively engage magnetic tape in a cassette which has been inserted into the recorder;
- and in a second direction transverse to said first direction of movement and transverse to said direction of tape transport, and
- means for supporting a cassette inserted in the recorder so arranged that when the magnetic head unit is in the operating position the position of the cassette is defined relative to the magnetic head, said means for supporting including a movable cassette supporting means integral with said head holder for supporting at least a portion of the cassette adjacent said at least one head, the position of the movable cassette supporting means in said second direction, when the magnetic head unit is in the operating position, being determined by the magnetic head unit, so that upon inserting a cassette into the tape recorder, and movement of the magnetic head unit to the operating position, the position of at least a portion of the cassette in said second direction is determined directly by the position of the magnetic head unit.

- means for mounting the magnetic head unit to the housing section to be movable relative to the section in a first direction between an operating position in which the magnetic head can operatively engage magnetic tape in a cassette which has been inserted in the recorder, and a retracted position in which a cassette can be inserted into or removed from the recorder, and while in the retracted position to be movable in a second direction transverse to the first direction and transverse to said tape transport direction between an unlocked retracted and a locked retracted position,
- means for locking the magnetic head holder while in the locked retracted position against movement in the first direction toward the operating position,
- means for supporting a cassette inserted in the tape recorder including a movable supporting means integral with said head holder movable in the second direction such that upon movement of the magnetic head to the operating position the position of the cassette is defined relative to the magnetic head,
- first resilient means for biasing the magnetic head holder along said first direction toward the operating position, and means for manually moving the magnetic head holder in opposition to said first resilient means from the operating position to the retracted position, and
- second resilient means for biasing the magnetic head holder along said second direction toward the locked position, and means for pressing the magnetic head support from the locked toward the unlocked retracted position in opposition to said second resilient means.
