ABSTRACT:
A small-sized and low-power magnetic tape recording and/or reproducing apparatus. A first idler is press-contacted with a driving roller provided coaxially with a capstan shaft for transporting a magnetic tape at a constant speed, the pressing force of the first idler being changed so as to obtain a driving force caused by friction according to the pressing force. The driving force of the first idler is transmitted to a relay wheel via a timing belt mounted on the first idler and the relay wheel, and to a reel drive turntable by a reel transmission mechanism. The reel transmission mechanism has a selective transmission mechanism which transmits the rotation of the relay wheel to a rotating wheel juxtaposed with the reel drive turntable and then to the reel drive turntable either directly or indirectly via a torque limiter provided on the rotating wheel.
