Abstract

PURPOSE:To obtain stable running of a tape, by constituting so that the tape runs at a high speed when a rotating speed of a rotary cylinder has reached a prescribed rotating speed. CONSTITUTION:When a high speed winding switch 11 is depressed, at first a signal is outputted to a motor control signal outputting circuit 2 from a mechanism controlling circuit 1, a cylinder motor 7 starts its rotation, and its speed is controlled to constant rotational frequency. Also, during this time, the controlling circuit 1 outputs a signal for controlling a take-up motor 6 and a feed reel motor 8 by a stop mode, to the circuit 2. Subsequently, when a signal informing that the rotational frequency of the cylinder motor 7 has reached a prescribed value is outputted to the controlling circuit 1, a magnetic tape 9 is made to run by a high speed winding mode through the motor control signal outputting circuit 2. Accordingly, in this way, stable running of a tape can be obtained without damaging the tape.
