Abstract

PURPOSE:To prevent the distortion of screen when playback is transferred from intermittent slow state to normal state, by taking synchronism between a rotating head and tape run from the beginning through the synchronism between switching pulse of the rotating head and slow still signal. CONSTITUTION:A head switching pulse or vertical synchronizing signal is inputted to monostable multivibrator circuit 12 from an input terminal 11, the output of the circuit 12 is inputted to a DFF13 inputting a slow still signal from an input terminal 14 and the output of the FF13 is inputted to a sample hold circuit 15, servo switching circuit 16 and intermittent slow playback circuit 17. Motor control amount is set to a motor drive circuit 18 driving a capstan motor with a servo circuit 19 by taking the outputs of the circuits 15, 16 as inputs. The circuit 16 switches the objective value of the circuit 19 according to the state of device, normal playback, intermittent feed slow playback and still playback, control amount is set to the circuit 18, the motor is controlled at the circuit 18 to make smooth the transfer from intermittent slow playback to normal playback.
