Abstract

PURPOSE:To obtain a slow reproduced picture without noise bar, by repeating the standard-speed reproducing without noise bar and the still picture reproducing without noise bar alternately to perform the slow reproducing. CONSTITUTION:The pulse train of a frequency determined by reproducing speed setting resistance 8 is generated by an oscillator 9, and this signal and a head switching signal inputted to a terminal 4 are inputted to an FF10. The FF10 detects the head switching signal, and the deviation between the head switching position and the vertical blanking time recorded on a tape is corrected by a delay circuit 11. A gate circuit 12 becomes conductive by the output of the circuit 11. When the number of pulses required for feeding the tape by a length corresponding to n-number frames is counted by a counter 13, the circuit 12 is cut off. A step motor 1 for driving a capstan is driven by pulses which pass through the circuit 12, and thus, reproducing in an optional speed is possible.
