Abstract

PURPOSE:To return the tape to the original slow-motion reproducing smoothly without the disturbance of the reproduced picture when the recording signal is detected again, by running a tape in the normal standard speed when the recording signal is not detected at the slow-motion reproducing time. CONSTITUTION:When a control signal (c) is not detected at a time T2 the Q output of an FF18 becomes high, and the output of a monostable multivibrator 20 becomes low after a constant time, and therefore, the output of an AND gate 21 becomes low at this time. Then, transistors TRs 22 and 23 are turned off. Since a TR24 is turned off also, the input to a motor drive amplifier 14 becomes a voltage applied from the output of a phase comparator 13 through a resistance 29. Therefore, a capstan is rotated in the standard reproducing speed. When the reproducing control signal (c) is detected again at a time T3, the Q output of the FF18 is inverted and becomes low. The inversion Q output becomes high, and the TR24 is turned on. Then, the input to the motor drive amplifier 14 becomes low to stop the capstan, thus entering into the original slow-motion reproducing smoothly.
