Abstract
PURPOSE: To secure the faithful running of the magnetic tape in the optional tape running command speed by detecting the running speed of the tape via the timer roller and then controlling the turning speed of the reel motor to the fixed tape speed.
CONSTITUTION: External reference signal 22 is supplied to phase comparator 26. On the other hand, pulse signal generator 28 is connected to the shaft of timer roller 17 and then supplies output pulse signal 18a featuring the frequency proportional to the running speed of tape 5 to frequency discriminator 28. Comparator 26 gives the phase comparison between the output signal and the reference signal to deliver phase error signal 27. And discriminator 28 delivers frequency error signal 29 by the input of signal 18a. Adder 30 performs the addition between signals 27 and 29 in order to give the control to the turning speed of motor 20 via the output signal. Thus the turning speed of the timer roller can be kept faithfully at the commanded tape running speed.
