Abstract: PURPOSE:To prevent a tape from being drawn out excessively, and to thin the whole of a device, by engaging a gear having a plane clutch with the gear on one side of the gears provided at a supplying reel base and a take-up reel base in a magnetic recording and reproducing device. CONSTITUTION:The gear 14 having the plane clutch 13 is engaged with the gear 6 provided at the take-up reel base 2, and the braking device of the reel base is extended in the horizontal direction of a chassis 1. And by rewinding the tape from a state where the connecting part 20a of a stopper 20 is connected to the connecting lug 16a of a clutch plate 16 by a driving mechanism, the appropriate level of loading torque is applied on the gear 14 by surface contact between the felt of the clutch plate 16 whose accompanying rotation with the gear 14 is stopped by the stopper 20, and the friction surface of the gear 14 driven with pressure to the felt side by a compression coil spring. Therefore, the appropriate level of braking is applied on the gear 6 of the take-up reel base 2 being engaged with the gear 14, thereby, the run idle of the take-up reel base 2 at time of rewinding the tape can be suppressed.
