Abstract

PURPOSE:To make it possible for one transmitter to control receivers individually by changing reference frequencies over by providing the transmitter with a required number of push buttons for control over one receiver. CONSTITUTION:Reference oscillator 2 of transmitter 1 oscillates at either of two reference frequencies fA or fB according to the position of frequency change-over switch 11; when the oscillation frequency is fA, ''0'' and ''1'' are of 2mses and 4mses respectively and when fB, ''0'' and ''1'' are of 1mses and 2mses as to its output signal (a). Then, this signal is supplied to signal generating circuit 3 to generate a pulse train showing ''0'' on the basis of the reference frequency. Next, it is frequency- divided to generate a pulse train showing ''1''. According to the operation state of push-button switch 30, signal (b) of ''01'' or ''10'' is generated to activate light emission diode 5 by driving transistor 4 and its light emission signal is received by receivers and demodulated, thereby operating and controlling only one specific receiver.
