Abstract

The present invention relates to a facsimile transmission installation adapted to allow rapid transmission of the contents of forms. In accordance with the invention, various types of blank forms are memorized and the transmission equipment includes a comparator connected to a memory and to an analysis circuit and allows the transmission of a facsimile signal which represents only the data added on the analyzed filled-in form and the reception equipment includes a text regenerator which operates from a transmitted facsimile signal and from a signal which comes from its memory.
