Abstract
A tape running direction indicator is provided with a sensor for producing a sense pulse corresponding to the rotation of a take-up reel, a ring counter clocked by the sense pulse, and a display unit which receives output pulses of the ring counter and includes decimal points arranged side by side for indication of the tape running direction. The output pulses of the ring counter are shifted corresponding to the direction of the tape running. A glint of each decimal point is successively shifted in the direction of the tape running while flashing.
