り構成したコードレス電話装置。 In a cordless telephone device that is configured to allow wireless communication between a base unit and a handset connected to a telephone line at a specific frequency, a call signal that enters the base unit from the outside or is generated from the handset. each of the base unit and the slave unit, each of which sweeps the reception channels of the reception unit in order to sequentially receive signals of a plurality of channels whose carrier frequencies are respectively assigned predetermined values according to the arrival of the detection signal; a sweeping means provided in;
Sweep stopping means for stopping the sweeping operation of the sweeping means in the base unit or slave unit at one empty channel;
A unique code signal pre-assigned between them and a channel code signal indicating the one empty channel are transmitted to the handset or base unit to which the calling signal has not been received, using the one empty channel. After receiving the channel code signal, the transmitting means provided in each of the base unit and the slave unit determines whether or not it matches the set unique code, and if it matches, the transmission means of the slave unit or the base unit Transmission/reception channel fixing means provided in each of the base unit and the slave unit for fixing the reception channel to the one free channel based on the received channel code signal, and also fixing the transmission channel to the one free channel; A cordless telephone device composed of
