<p>PURPOSE:To prevent a reproducing signal from being interrupted on the way even if a mechanism of the other side performs program search for a tape to be reproduced next when the magnetic tape is reproduced, by providing a storage means which stores a mechanism driven at first, switches a switch circuit and holds the switch circuit until the said mechanism is stopped next. CONSTITUTION:When the 1st mechanism is operative, that is, when an R input of an RS flip-flop 41 is ''H'', an S input is ''L'' and a Q output is ''L'', and when the 2nd mechanism is operated, or when the 2nd mechanism is operative, that is, the R input of the FF41 is ''L'', the S input is ''H'', and the Q output is ''H'', and when the 1st mechanism is operated, then the R and S inputs of the FF41 go to ''H'' in both the cases. Thus, the Q output is not inverted and the preceding output state is kept, allowing to keep the present state for the switch circuit 31 without inversion.</p> |
