Abstract
PURPOSE:To eliminate the need for a handset cord for a telephone set by coupling a telephone set main body and the handset in radio communication. CONSTITUTION:In case of hooking off a handset B from a telephone set main body A, hook switches 3,13 are closed to form a DC closed loop to a telephone line l and operating power is supplied from the power supply 12 to the reception circuit 8 and the transmission circuit 9 and the switch 21 is closed at the handset B and the operating power is supplied to the reception circuit 16 to the transmission circuit 17 from the power supply 20 and the telephone set main body A and the handset B are counpled in radio by using two radio waves whose frequencies are respectively F1 and F2. Then the transmitted voice given from the handset 15 is superimposed on the radio wave whose frequency is F1 by the transmission circuit 17, radiated from the transmission antenna 19 of the handset B and made incident on the reception antenna 10 of the telephone set main body A, received and demodulated by the reception circuit 8 and becomes the original transmission voice and inputted to a transmission terminal 701 of the speech circuit 7 and sent to the telephone line 1.
