PURPOSE:To prevent the recording of an image irrelevant to reception image by providing an annular line buffer that stores such number of lines of image information equivalent to a time necessary for identifying the end of the image information in the unit of line. CONSTITUTION:At the time of starting the reception, all the line buffers LB 1-LBn of the line buffer memory 4 are cleared, counters C, D are initialized to zero so that a pointer A points the line buffer LBm and a pointer B points the line buffer LB1. Thereafter, the coming-in of image information from a transmission-side equipment ends, the carrier wave stops, then a reception processing rutine ends, and thereafter, a plotter 6 no longer outputs images for recording. Therefore, an image signal received at the last time To that is, a senseless image information obtained by receiving a message end signal EOM, is not outputted for recording by the plotter 6.
