FIG. 1 shows a system configuration of a word processor according to the present invention. A CPU 1 controls creation of a two-dimensional bar code, recognition of a two-dimensional bar code, management of each editing mode, printing of each editing mode, and the like. I do. Memory 2 has R
It is composed of an AM text memory, a work area, and a ROM program (which can also be partially written to RAM) memory, and part of the information can be read from the external storage device 5 and reused.

The display unit 3 is composed of a CRT or a liquid crystal display, is a display output part of a user interface, and displays the contents of the text memory of the RAM as required.

The printing unit 4 is a printer that prints out the contents of the text memory in response to a request.
The input unit 6 is an operation unit for realizing a character conversion processing function. Function keys corresponding to function guidance displayed on the display unit 3, execution and release keys for controlling a program, and a text memory are additionally corrected. It is a full keyboard composed of type input keys to be operated, and cursor keys for operating coordinates of the display unit.

The scanner input unit 7 inputs information of a print sheet printed by the printing unit 4 or other sheet information as an image, and inputs data as text information to a text memory by the operation of the CPU 1. Input unit 6
In the coding process operated by the, the display unit 3 displays a line of a text memo or displays two divisions.

According to the present invention, a two-dimensional bar code is inserted into the text memory by inserting a coded page break control code, a summary control code, a title control code, etc., separately from the conventional document page break control code. This allows editing using a two-dimensional barcode that is suitable for the purpose. Further, these printed materials and the like are taken in from the scanner input unit 7 so that the data can be reused.

Next, the two-dimensional barcode used in the present invention will be described. As shown in FIG. 2, as for the relation between a print document and a two-dimensional barcode, it is assumed that a print example is 64 dots × 64 dots / character, and there is no space between characters and lines in the description. Ku code 040 of "A" as a code example
2 is represented by 2 bytes, that is, 16 bits. Even when 1 bit is converted into a two-dimensional bar code by 4 dots, the data length is 16 dots × 16 dots.

According to the present invention, not only character information (printed text information) is printed but also converted into a two-dimensional bar code and printed on a sheet medium at high density. Therefore, if the two-dimensional barcode printed on the sheet medium is read by using a reader such as a scanner, the type information can be easily reproduced. In general, a two-dimensional barcode can reduce the amount of information compared to print, and can output a document having a large number of pages with a small number of pages, thereby facilitating paper management. In addition, since the print content is not printed, the document information can be kept secret and managed in a sheet. Further, since the information can be managed on the sheet medium, the file related to the management can be easily stored, and the information can be copied by a simple copy. It is possible to greatly expand information distribution by printing a large amount of information. Unnecessary print information can be easily extracted or replaced, and incineration can be easily performed.
