Abstract: A cassette-type tape recorder device comprising a movable carriage into which a tape cassette is removably engageable to be operatively received in the apparatus. The apparatus has a support frame with guiding means along which the carriage is linearly slideable in the longitudinal direction of the apparatus to locate the cassette in a received operative position in the apparatus, the carriage being slideable such that the active length of the magnetic tape in a cassette is caused to move parallel to the direction of displacement of the carriage along the guide means.Tape dragging means are carried by a vertically movable supporting plate which is located beneath the carriage. Guiding means are provided for retaining the supporting plate and for displacing the supporting plate mainly in the vertical direction while always maintaining the supporting plate substantially parallel to the bottom of the carriage, thereby insuring proper engagement of the tape dragging means with the bobbins of the cassette.
