Abstract
PURPOSE: To perform multiple processings with one coding circuit and subject additional information to the code processing as an original picture mode by processing collectively plural facsimile signals in the time division system and storing additional information as picture signals previously.
CONSTITUTION: A coding circuit is constituted by sampling circuits 7A∼7D which sample facsimile signals inputted from plural lines and have original picture mode input terminal 713, run length counter 8 which counts length of each run of sampling signals in time division, FIFO memory 9 which stores output signals of counter 8, and run length coding unit 10 which codes output signals of memory 9 to a run length code in time division and converts output signals of memory 9 to sampled facsimile signals when an original picture mode designation signal is applied to input terminal 713. By this constitution, increment of the number of coders is not required in case of a large number of lines, and additional information such as transmission date can be added to facsimile signals.
