Facsimile apparatus for line by line recording of different kinds of weather map, satellite and other graphic data distinguishes the different characteristics of the transmitted electrical data signals and records them in suitable aspect ratio, despite the fact that the various signals are transmitted at different line rates and are intended for recording at different line densities. The apparatus also enhances the contrast of the recording and can enlarge the original graphic information.

Recording graphic data of different transmission rates

A facsimile recorder of moist electrolytic recording paper includes a tray under the helical scanning electrode which traverses the paper. The tray performs the dual function of collecting chaff abraded from the paper by the scanning electrode and of containing a supply of moisture for the paper.
