ABSTRACT:
Rotational speed of a flywheel directly coupled with a capstan is detected by a speed detector. The rotational speed data and the reference speed data are supplied to a comparator/arithmetic circuit whereby actual tape running speed relative to the reference speed is calculated. Data outputted from the comparator/arithmetic circuit is supplied to a display device whereby relative value of the actual tape speed with reference to the reference speed is displayed.
