Abstract
PURPOSE: To increase the accuracy of indication in a low tape speed, by counting the pulses according to the rotational frequency of the reel drive disk after dividing said pulses in accordance with the tape running speed.
CONSTITUTION: The rotary power of the take-up reel drive disk turns the magnet 11 magnetized by the belt 10. And the pulses according to the rotational frequency of the reel drive disk are obtained via the reed switch 12 and the pulse generator 13 and then applied to the divider 14. For the divider 14, the division ratios are set as follows by the switch 17 interlocking the tape speed change-over switch: 1/1, 1/2 and 1/4 at the tape speeds of 9.5cm/sec, 19cm/sec and 38cm/sec respectively. The output of the divider 14 is supplied to the display driving means to actuate the display unit 16.
