Abstract
PURPOSE: To secure a high-quality reproduced picture frame even at a high-speed time by applying the drum servo in order to secure always a constant frequency for the horizontal synchronous signal in the reproduced signal.
CONSTITUTION: The horizontal synchronous signal in the reproduced signal sent from half H-killer circuit 30 is supplied to switch circuit 46 along with the horizontal synchronous signal underwent AFC and sent from switch circuit 35. At the same time, these signals are supplied to decision circuit 47 to extract the signals sent from circuit 35 or 30 through switch circuit 46. The signals from circuit 46 are supplied to frequency comparator circuit 48. At the same time, the signal featuring the oscillation frequency of 15.625kHz and sent from oscillator 49 is supplied to circuit 48 as the reference signal. The comparison output is supplied to voltage control type variable frequency oscillator 51 through low pass filter 50, and the output of oscillator 51 is supplied to drum motor 52.
