Abstract

PURPOSE:To control a tape speed with high accuracy in simple constitution by controlling a driving motor in its drive in response to a control signal detected by a detecting means. CONSTITUTION:The titled device is equipped with a magnetic head 11, a wave shaping circuit 12, a leading edge detecting circuit 13, an AND circuit 14, a mask circuit 15, a speed detecting circuit 16, a filter 17, a motor driving amplifier 18 and a driving motor 19. Then, when a leading edge is once inputted out of an inputted waveform signal S4 to the mask circuit 15, its output S4 is then held at an L level for a fixed time only, and a control signal to be inputted is herein masked, and its acceptance is prohibited. For this, irrespective of any tape traveling mode, the wave S4 is inputted always at a fixed periodical interval to the speed detecting circuit 16, and the drive motor 19 is controlled in its drive in accordance with a tape traveling mode, based on an input signal by the motor driving amplifier 18. By this method, the tape speed can be controlled with high accuracy with simple constitution.
