ABSTRACT:
A facsimile apparatus having a transmitting unit for scanning an image of a text to produce an image information signal and converting the image information signal to a coded information signal in a band compressed transmission system for transmission through a transmission line, and a receiving unit for decoding the coded information signal transmitted through the transmission line to reproduce the image information on a recording medium, the facsimile apparatus includes a memory having a memory capacity of at least one page information of the text for storing the information signals representing the image of the text to be transmitted and received. The receiving unit includes clock generator for generating a timing clock for reading out the received information signal stored in the memory converting circuit for converting the information signal read out from the memory means into analog information signal, and scanning type recording medium for feeding the recording medium at a constant speed and recording the image on the recording medium in accordance with the analog information signal read from converting circuit. The memory is responsive to the timing clock from the clock generator to sequentially read out the information signal such that a scanning-start timing at each scanning line in the recording medium is repeated with a constant period.
