Abstract

An office communications system wherein, for the manipulation and/or transmission of text available in an already printed form, a text converter is connected between a word processing terminal and a telecopier. The text converter includes a classifier memory which stores the desired classifier data and a character recognition unit wherein uncompressed image data received from the telecopier are evaluated by means of the classifier data and then transmitted as text data to the word processing terminal for further processing.

Claims

1. An office communications system for the manipulation and/or transmission of image and text data via a communications network comprising in combination:

a word processing terminal connected to a communications network for transmitting and receiving text in the form of character data via the communications network;

a telecopier connected to the communications network for transmitting and receiving image data via the communications network; and

means for permitting the editing of text in the form of image data supplied by said telecopier and the transmission of said text as character data via said communications network, said means including text converter means, connected between said telecopier and said word processing terminal, for converting image data of text pages received from said telecopier to character data of the code type used by said word processing terminal and for feeding the converted data to said word processing terminal, said text converter means including a character recognition unit having a data input connected to an output of said telecopier and a data output connected to an input of said word processing terminal, and a classifier memory for storing desired classifier data connected in data exchange with said character recognition unit.

2. A system as defined in claim 1 wherein said word processing terminal, said telecopier and said text converter means comprise one of a plurality of similar user stations connected to said data communications system.

3. A system as defined in claim 1 wherein said classifier memory is a plug-in unit.

4. A system as defined in claim 1 or 2 wherein said classifier memory is a read only memory.

5. A system as defined in claim 1 wherein:

said classifier memory is a random access memory (RAM); and

said text converter means is provided with a further input for receiving classifier data for charging said random access memory.

6. A system as defined in claim 5 wherein said word processing terminal includes a diskette storage means for storing classifier data;

and wherein said further input is connected to an output of said word processing terminal.

7. A system as defined in claim 5 wherein:

said further input is connected to an output of said word processing terminal; and

wherein means are provided at a location remote from said word processing terminal for transmitting desired classifier data to said word processing terminal via the communications network whereby said classifier memory of said text converter means can be charged with classifier data transmitted via the word processing terminal.

8. A system as defined in claim 7 wherein:

said word processing terminal, said text converter means and said telecopier comprise one of a plurality of similar user stations connected to said data communications network; and

said means for transmitting classifier data to said word processing terminal comprises an adaptation laboratory including means responsive to receipt of a text page transmitted via said communications network by the telecopier of one of said user stations for determining the desired classifier data for the received text pages and for transmitting the determined said desired classifier data via the communications network to the word processing terminal of said one user station.

9. A system as defined in claim 1 wherein said word processing terminal includes a central processing unit, and a keyboard for entering character data, a memory or storing character data, and a monitor for displaying character data, all connected to said central processing unit;

and wherein said input of said word processing terminal is an input to said central processing unit.
