御装置。FG servo control means for performing frequency-to-voltage conversion on a frequency signal corresponding to the rotational speed of the rotary body, and then comparing the frequency signal with a reference voltage to drive and control the rotational speed of the rotary body to a predetermined value; and phase detection means for phase-detecting the control frequency signal and the frequency signal, and after frequency-voltage conversion of the control frequency signal, the output voltage of the phase detection means is added to the output voltage of the phase detection means to detect the FG servo. A rotation speed control device for a rotating body, characterized in that the reference voltage of the control means is used as a reference voltage.
