Abstract
A back spacing apparatus for a transcribing machine comprises a first means for providing a first signal (a) corresponding to the period of rotation of a supply reel or a take-up reel, a drive source for rewinding a tape toward the supply reel and a second means for providing electric energy (Tm.times.V) corresponding to the period (Tm) of the first signal (a) to the drive source for rewinding to vary the r.p.m. of the supply reel at the time of rewinding the tape toward the supply reel or the period of the rewinding operation according to the first signal (a). The magnitude (Tm.times.V) of the electric energy is varied in accordance with the period (Tm) of the first signal (a) for making the length of the tape rewound toward the supply reel substantially constant irrespective of the diameter of the tape rolled on the supply reel.
