Abstract
PURPOSE: To highly accurately locate a tape irrespective of the high and low speeds of the tape by counting the number of rotation detecting pulses, which are contained in two longer and shorter kinds of refrence pulse periods, thereby to locate the tape.
CONSTITUTION: Rotation detector 7 and 8 are arranged on reel drive shafts 5 and 6 so that one pulse A may be generated each one rotation of the shafts by means of detecting elements 9 and 10 and fed to counters 11 and 12, where count control pulses B having a pulse width of time T are generated. On the other hand, the reference pulses C are fed from a counter circuit 13 to the counters 11 and 12 to count the number of the pulses C which are contained in the time T. The circuit 13 feed the reference pulses of a shorter period t2 to the counters 11 and 12, when under its intial condition, but is made responsive to the frequency change-over signals from the counters 11 and 12 to convert them into the reference pulses of a longer period t1. The reel rotation period is detected with the reference pulses of the shorter period t2 at the higher speed and with the pulses of the longer period t1 at the lower speed so that the performances of the counters 11 and 12 and the counter circuit 13 may be obtained at their maximum levels at each speed, thus making it possible to highly accurately locate the tape at each speed.
