Abstract
A facsimile apparatus of analog type is disclosed, in which, in order to shorten the transmission time, continuous white lines of the white background of the original are read variably in number during each scanning line period. The information thus read is transmitted to the receiver in synchronism with the scanning line period. At the receiving end, the recording paper is rapidly fed for the scanning line period corresponding to the number of lines representing the received information.
