PURPOSE:To decrease various noise and missing of information on a original and to improve the quality of the original received again and to decrease the communication time, by synthesizing the information stored at a transmission side with the information for addition and correction transmitted from a receiving side, and outputting the result. CONSTITUTION:When the original of transmission 1 is read at a document and picture reading section 2, the document and picture information is stored in a memory 4 sequentially with the control of an address counter 5, address information is added 6 and transmitted via a modulation circuit 7. Further, the document and picture information received again is given to a detecting circuit 24 via a demodulation circuit 23, the address information of the memory 4 is detected, its address is set to the counter 5 and the document and picture information received again is transmitted to an OR circuit 25. The counter 5 is advanced stepwise with a clock of a generating circuit 3 when the setting of the address is finished, and the document and picture information stored in the memory 4 is transmitted to the circuit 25 sequentially. An output of the circuit 25 is given to an output section 26, the logical sum information is printed and outputted as the original 27 received again. |
