Facsimile transmission installation in particular for copying forms
First Claim
1. A facsimile transmission installation for transmitting documents which include a portion which is common to a plurality of transmissions and a portion which may vary from transmission to transmission, such documents being referred to as forms;
- the installation comprising a transmitter terminal including a document analyzer together with means for generating a facsimile signal therefrom, a receiver terminal including means for receiving the facsimile signal together with a document reproducer responsive thereto, and means for conveying the facsimile signal from the transmitter terminal to the receiver terminal wherein each terminal includes a memory for recording the portions of documents which are common to a plurality of transmissions, the recorded portions of documents being referred to as "blank forms", means for selecting a particular blank form from the memory;
wherein the transmitter terminal includes a comparator connected to the memory and to the analyzer to receive respectively a memorized signal and an analysis signal therefrom and to generate in response thereto a useful signal representative of the difference between the completed form being analyzed and the memorized blank form, and a date compression encoder connected to receive the useful signal and to generate said facsimile signal; and
wherein the receiver terminal includes a decoder-expander to receive the facsimile signal and to restore the useful signal therefrom, and a generator connected to said decoder-expander and to the receiver memory and to receive respectively the useful and the memorized signal therefrom and to generate in response thereto a restored analysis signal which represents the contents of the completed form and to apply the restored analysis signal to the document reproducer.
