Abstract

PURPOSE:To prevent malfunction due to noise and the like, by counting a received serial data number and inhibiting a remote control operation if the result of count is dissident with a prescribed number. CONSTITUTION:A signal number discriminating circuit 13 is provided in connection with a waveform shaping circuit 5 and a deciding circuit 9. The circuit 13 counts the number of received data by counting the number of carrier wave domains D1-D2, and if the data train of information signal A1 or A2 is subjected to interference such as missing of bits or excessive data, a signal of defective decision is outputted and given to the circuit 9. When the reception of the signals A1 and A2 in 10-bit is decided, the inhibition of output of the circuit 9 which makes the discrimination of coincidence of registers 7 and 8 is not made. On the other hand, if the two sets of the signals A1 and A2 are not done, the signal output of the circuit 9 is inhibited. Thus, if the normal data number of the remote control transmission signal can not be received due to noise, since no output of remote control is made, malfunction can be avoided.
