Abstract

PURPOSE: To enable stable reversing reproduction, by using lead-out reel without a torque limitter. CONSTITUTION: After a magnetic tape 1 pressed with a capstan 14 and a pinch roller 15 and led out with a fixed speed, is wound on a cylinder having a rotating magnetic head and run, the reversing playback of picture is made while the tape is wound around the reel. As a reel 17, a lead-out reel 22 without a torque limiter is used, and a DC motor 24 is used for a driving source of the reel 22, and a speed reduction mechanism is placed between the reel 22 and the DC motor 24 and the gear ratio of the reduction mechanism and the constants of the DC motor 24 are selected so that the tension at reversing can almost be constant independently of the number of revolutions of the reel 22.
