Abstract

PURPOSE: To enable to correctly display the shift of tape speed, by comparing the signal obtained through frequency division of reference frequency signal and the signal obtained through the frequency division of the signal detected from the rotating body related to the tape speed, at the phase comparator.
CONSTITUTION: The signal obtained through the frequency division of the signal from the reference signal generator 1 with the first and second frequency dividers 2, 3, and the signal obtained through the frequency division of the signal detected at the revolution detector 4 with the frequency divider 5, are fed to the phase comparison circuit 7 to detect the special state of each signal shown when the rotating speed of the revolving body is shifted from the standard speed. The shift of the tape speed can easily be displayed digitally since the gate circuit 13 is set with the signal detected and count is made by applying the reference frequency signal is fed to the counter 14. Further, the display for advancement or delay is made by the signal different depending on the advancement or delay of the revolving speed of the rotating body from the specified speed at the phase identifying circuit 16.
