PURPOSE:To print only the desired screens of an object with an optional distance by unifying a facsimile with a TV telephone. CONSTITUTION:A transmission part T amplifies 2 the voice signal supplied from a transmitter microphone 1 and supplies it to a transmission synthesizing part 5, and the picture signals sent from an image pickup part 3 are stored to a transmission buffer 4. A switch SW7 is set in a TV telephone mode when contacts A and C are closed and in a facsimile mode when contacts B and C are closed and changes the communication speed and the communication type in accordance with these modes. A control part 6 reads out the picture signal from the buffer 4 in response to the signal sent from the SW7 and synthesizes 5 it with a voice signal to send them to a telephone circuit 16 via a transmission/ reception separating circuit 15. The signal sent from the circuit 16 is applied to a signal analyzing part 12 of a reception part R via the circuit 15. The part 6 controls the part 12 for analysis of a facsimile signal and stores the picture signals to a reception buffer 11 to display them at a picture receiving part 9. Then a picture is printed 8 after an SW10 is closed. In a TV telephone mode, the picture given from the part 12 is displayed 9 and at the same time the voice signal is amplified 14 and sent to a telephone receiver 13.
