Abstract

PURPOSE:To permit of one-behavior operation and prevent wrong selection, by detecting the coincidence of a selecting signal. CONSTITUTION:A signal 3 received from a master station is applied to a series- parallel conversion circuit 5 through an FS demodulation circuit 4. The conversion circuit 5 converts the signal into a parallel code train. The selecting signal is stored in a primary storage circuit 6 and is changed into a contact signal through a selecting relay circuit 8. An operating signal is picked up from an operating signal primary storage circuit 7 by a coincidence detection signal 13 which is generated by a selecting signal coincidence detection circuit 12 and which means that the signal stored in the selecting signal primary storage circuit 6 has coincided with a new selecting signal. The contact signal generated by the selecting relay circuit 8 and an operating relay circuit 9 is applied to an operation instructing circuit.
