Abstract

PURPOSE:To always obtain an easy-to-see still picture image by detecting the drop- out of the video signal caused by the mistracking to obtain the stop time point and then stopping the tape at the position where no noise band occurs on the screen at the still reproduction time point. CONSTITUTION:Switch signal A produced through the actions excepting the still reproduction action of the magnetic picture recorder/reproducer of azimuth recording system possessing the still reproduction mechanism is switched to the still action. After this, voltage J to be supplied to capstan motor 10 via capstan control circuit 24 is lowered down to the prescribed level in order to reduce the running speed of magnetic tape 5. And the presence or absence is detected for the drop-out of the video signal reproduced from magnetic tape 5 after reduction of the running speed through drop-out detection circuit 12 at every time point when the fixed phase shift is caused from the vertical flyback time. Then FF20 is controlled by signal H which gives inhibition for a fixed period after generation of signal A to the detection output of circuit 12, head switching signal C detected through tack head 7 and the detection signal of circuit 12. Then stop signal I of motor 10 is delivered.
