Abstract

PURPOSE:To realize an assured remote control by giving attenuation and discontinuation to the call signal via the circuit featuring the highest action sensitivity and highest action time when the remote control circuit arrives at the connection circuit. CONSTITUTION:Remote control signal SR given from input terminal T1 and T2 is amplified 5 through connection circuit 1 and then undergoes frequency selection 6, and then really necessary SR only is sent to 1st and 2nd control circuits 7a and 7b. Here the relations of Ga>Gb and Ta>Tb exist between circuits 7a and 7b as to action sensitivity G and action time T. Accordingly, circuit 7a operates first, and the control signal accompanied to the operation is applied to reproduction signal sending circuit 4 in order to discontinue the operation or attenuate the transmission output. Thus, if the signal is supposed to be transmitted from circuit 4, SR is lessened but both discontinuation and attenuation are strengthened for the transmission signal sent from circuit 4. Accordingly, circuit 7b starts operation and remote action control circuit is actuated by the control output. And the remote control is given to the remote-controlled part.
