| 摘要 |
The invention discloses a magnetic recording-reproducing device wherein a reversible motor is drivingly coupled to two one-way rotary clutches one of which is engaged when rotated in one direction and the other of which is engaged when rotated in the other direction and to a capstan shaft for transporting a tape at a constant speed, and the one-way rotary clutches are drivingly coupled to two reel shafts, respectively, whereby depending upon the direction of rotation of the reversible motor, either of the reel shafts is selectively driven together with the capstan shaft.
