Abstract
PURPOSE: To obtain accurate count values irrespective of speeds by specifying the period of the pulses being generated at a specific rate with respect to the rotating period of a rotator and changing over count modes according to operation modes.
CONSTITUTION: A pulse generator 8 constitutes a frequency divider of n:1 with a pulley 6 driving a tape driving reel shaft 5 and a disc electrode 10 driving pulley 9. Pulses of "1", "0" are generated by a detector 11 making elastic contact with the electrode 10 and are inputted to a one-shot circuit 13. The trigger pulses from the circuit 13 are inputted to a logic part 14 and are then applied respectively for count controllers 15a, 15b for the high speed and low speed time via ANDs 17, 18 to let a code signal (n) be outputted in a code generator 19 each time when the count command signal is emitted from the AND 20 of the controller 15a, causing a counter circuit 16 to be driven via OR 21. The controller 15b causes the circuit 16 to count the pulse separations up till the time when the next trigger pulse is generated. Thereby, the accurate count values such as the number of revolutions, etc. may be obtained irrespective of speeds.
