<p>PURPOSE:To stop a tape at a prescribed tape position by executing only once a tape stopping processing within a slow or still reproduction rushing process by using properly a slow tracking monostable multivibrator means. CONSTITUTION:When a rush to the slow or still (S/S) reproduction is instructed from a VTR entirely system controller, a CAP motor servo IC13 switches an ordinary reproducing control to a slow intermediate speed control. An S/S controller 10 switches a wait for the input of a reproducing control signal f' and the slow tracking monostable multivubrator circuit (TRKMM)11 to an instantaneous stopping. Thereafter, at the time of inputting the signal f', the tape is stopped due to the generation of a counter torque to a CAP motor 12 of the same as ordinary frame feed using the slow TRKMM for the instantaneous stop to be stopped at the prescribed tape position. the MM circuit 11 is switched to the ordinary frame feed for executing the ordinary frame feed thereafter to feed the frame.</p> |
