Title: Servocircuit of capstan motor
Inventor: KIHARA NOBUYOSHI
IPC: G05D13/62
Filed: 1979-09-13
Abstract: PURPOSE:To get rid of servo-disorder at the change-over point of recording-reproducing-recording, by providing reset signals of the counters of both the reference signal side and the reproducing signal side to the other side, respectively. CONSTITUTION:Even in case the tape deck is ready for play, the recorded reference signal is not reproduced exactly until a speed of the tape becomes constant, therefore the mode of switches S1-S3 is same as the recording time and is subject to servo- operation by a signal from the reference signal generator 14, and when the speed of the tape becomes constant, the reforded recerence signal becomes contstant and the reforded recerence signal is reproduced exactly, each switch is automatically changed over to the reproduction mode and is subject to servo-operation by a reproducing reference signal from the tape 18. In this case, since the counter 21 which counts down the reproducing reference signal from the tape 18 is reset by the counter 15 which counts down the reference signal from the generator 14, the outputs of both the counters become in the same phase. Accordingly, the servo-disorder at the mode change-over point by the switch can be prevented.
