Abstract

PURPOSE: To perform the signal transmission of facsimile efficiently even if the buffer memory capacity of transceiver is different, by constituing that the monitor of remaining buffer memory of the reception side can be made at the transmission side.
CONSTITUTION: The facsimile signal from the signal read-in section 1 is fed to the buffer memory 4 via the coder 2 and fed to the recording time measuring section 3 counting the code length every scanning line and required recording time. The reception side buffer memory remaining amount detector 11 receives the signal from the measuring section 3 and the coder 2 and detects the remaining amount of the reception side buffer memory 8, and when this remaining amount is zero, the dummy signal from the code generator 6 is inputted to the buffer memory 4. The buffer memory remaining amount monitor section 5 at the transmission side controls the operation of the coder 2 so that the buffer memory 4 is not overflowed.
