送装置。A signal to identify the end position of each line is added to the line-by-line data to be transmitted, and the data is sent to the receiving side in increments of a predetermined number of lines, which is less than the number of lines for one page. In addition, there is a transmitter that stores the transmitted data in a memory for retransmission and retransmits only the data of the line for which a retransmission request has been made to the receiving side, and a transmitter that stores the data sent from the transmitter. It memorizes whether the data belongs to the line, checks each line for errors in the sent data, sends the number of the line where the error occurred to the sending side, and requests retransmission of the data on that line. What is claimed is: 1. A data transmission device comprising: a receiving section.
