PURPOSE:To automatically display either one of a recorded input signal or a recorded signal on a tape, by providing two analog switches. CONSTITUTION:Terminals 14 and 15 are connected to a system control circuit and a negative pulse is inputted. This negative pulse is applied to an RS-FF 16. When the instruction of ''recording'' is given with an operation mode for example, a negative pulse is applied to the terminal 14 and an output Q' is reset to ''L''. Further, if a negative pulse with the reproducing operation is inputted to a terminal S, the output Q' is fixed to ''L''. This output turns on an analog switch 13, to flow a signal recorded on the tape to an amplifier 10 to an output terminal 11. In case of ''Pause'', a negative pulse is applied to a terminal R of the FF 16 and the state is inversed. |
