ABSTRACT:
A dual cassette tape recorder comprises a cassette receiving means adapted to receive either a compact tape cassette or microtape cassette. The cassette receiving means is associated with a capstan and a pinch roller adapted to engage and drive a tape in the compact cassette, and with a pair of a capstan and a pinch roller adapted to engage and drive a tape in the micro-cassette. Drive means is provided for driving the both capstans. An interlocking lever is provided which detects a displacement of the pinch roller associated with the compact cassette during a recording or playback operation for operating the pinch roller associated with the micro-cassette, thus permitting a satisfactory recording or playback operation when either type of cassette is mounted in the cassette receiving means.
