ABSTRACT:
A facsimile communication system includes a transmitter for transmitting data in a state where a minimum value of a total amount of data to be transmitted for each scanning line is secured, the data for each block including image data, and a receiver for receiving the data transmitted from the transmitter. The receiver has a memory for storing the image data out of the data received for each scanning line by the receiver, a printer unit for performing a printing process using the image data read out from the memory, a checking unit for determining, based on an amount of image data which has not been used for printing yet and remains in the memory, whether or not the minimum value of the total amount of data to be transmitted for each scanning line can be changed, and a signal output unit, when the checking unit determines that the minimum value of the total amount of data to be transmitted for each scanning line can be changed, for outputting a request signal, the request signal being transmitted to the transmitter. The transmitter has a detecting unit for detecting the request signal from the receiver, and changing means, when the detecting unit detects the request signal, for changing the minimum value of the total amount of data to be transmitted for each scanning line, so that the data is transmitted in a state where a changed minimum value of the total amount of data to be transmitted for each scanning line is secured.
