<p>PURPOSE:To improve the reliability of a magnetic recording/reproducing device by providing a pulley part which transmits the revolutions to a tape take-up means from a capstan drive motor via a belt and a transmission means which transmits the motive power with branching to a cassette loading means via the pulley part. CONSTITUTION:A magnetic tape 1 is drawn out of a cassette 17 attached on a substrate 10 and has a contact with a cylinder 19 for record or reproduction. Then the tape 1 is held between a capstan 2a attached to the axial core of a capstan drive motor 2 and revolved in a body with the shaft of the motor 2 and a pinch roller 3 and driven by the motor 2 toward and arrow head A at a fixed speed. While the revolutions of the motor 2 are transmitted to a pulley part 5a via a belt 4 hooked over a pulley 2b set coaxially with the motor 2. Then the motor revolutions are transmitted to a motive power gear 22 of a slide clutch mechanism 21 via a gear 20 engaging a gear part 5b formed in a body with the part 5a.</p> |
