遮断回路。A microcomputer detects the on/off operation of the press switch and controls the transmitter's transmission and reception.In the wireless equipment's erroneous transmission cutoff circuit, which stops the transmitter in the event of an erroneous transmission, the transmitter's transmission output detection signal and the press are used. a matching circuit for matching on/off signals of the switches; and the matching circuit outputs a signal corresponding to the off signal of the press switch, and turns off the transmitter when receiving a transmission detection signal of the transmitter. a detection circuit made of a NOR circuit that outputs a signal for turning off the transmitter, and a time constant circuit made of C and R for delaying the signal for a certain period of time when receiving a signal to turn off the transmitter from the detection circuit; A flip-flop circuit for preventing chattering consisting of two NOR circuits which input the output of the time constant circuit; When a signal to turn off the transmitter is received from the circuit, the off signal is output even when the transmitter on signal is received from the microcomputer.
An erroneous transmission cutoff circuit comprising: NOR circuits; and a transistor for controlling transmission of a transmitter based on the output of the NOR circuit.
