Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is a word processor that can specify a plurality of graphic areas in a document and has a graphic creation function that creates a desired graphic in the graphic area. Regarding Setsa.

(b) Conventional technology Some word processors have a graphic creation function, such as Sanyo's word processor SWP-
As disclosed in the 1100 operation manual, a graphic creation mode is entered by operating a specific key such as a graph key or a graphic key during document creation. In the figure creation mode, first, a figure area indicating an area in which a figure is to be written is specified using the cursor keys, and then a desired figure is drawn within this figure area. Furthermore, as shown in Fig. 4, the display screen 1
In this case, the graphic area 2 is framed by ruled lines, and when the cursor 3 is moved within the graphic area 2 and the above-mentioned graph key or graphic key is pressed, the cursor 3 changes to a cross-shaped graphic cursor (crosshair cursor) 4.

Generally, in such a word processor, the data storage area for one document is a character text section 5 that stores character data, as shown in FIG.
and a graphic data section 6 for storing graphic data.

Conventionally, consecutive graphic area numbers are assigned to a plurality of graphic areas within one document, and in the character text section 5, the graphic area number is written in the entire data area corresponding to each graphic area, and the graphic area number is In section 6, graphic element data corresponding to drawn circles, straight lines, etc. is written for each graphic area.

For example, as shown in Figure 6, if graphic area 1 and graphic area 2 are designated in the document, and a circle and a square are drawn in graphic area 1, and only a circle is drawn in graphic area 2, then As shown in Figure 7,
In the character text portion 5, a graphic area number is written in the entire data area 7 corresponding to the graphic area 1, a graphic area number is written in the entire data area 8 corresponding to the graphic area 2, and the graphic area number is written in the entire data area 7 corresponding to the graphic area 2. , graphic element data indicating circles and squares in graphic area 1 and graphic element data indicating circles in graphic area 2 are separated by a separator 9 and written. Needless to say, the graphic element data includes not only data indicating the type of figure such as a circle or a straight line, but also data such as center coordinates and radius.

(c) Problems to be solved by the invention In conventional word processors, consecutive graphic area numbers are assigned to multiple graphic areas within one document, but this numbering is not done for each document. Therefore, when you execute a document call and load another document containing a graphic area, the graphic area number written in the recalled graphic area may become the same as the graphic area number of the original document. Or, since the numbers are not consecutive, it is necessary to perform the troublesome number management work of rewriting the numbers of the called graphic area to consecutive numbers.

For example, in FIG. 7, when a document 11 having a graphic area 10 between graphic areas 1 and 2 in which a graphic area number is written is called, the contents of the graphic data section 12 will be changed as shown in FIG. ,
Although it is only added to the graphic data section 6 of the original document, all the graphic area numbers in the character text section 13 are rewritten to consecutive numbers and inserted into the character text section 5.

Also, when specifying multiple graphic areas, it is necessary to check the size of the graphic areas so that they do not overlap, but conventionally, the graphic area number was simply written in the text section. The problem was that the size of the graphic area could not be checked without the troublesome task of searching for the graphic area number in the text section.

(d) Means for Solving Problems The present invention provides a graphic data storage area that stores graphic element data for each of a plurality of graphic areas, and a graphic element data storage area that stores graphic element data for each of a plurality of graphic areas. It consists of an area definition data storage area that stores area definition data that defines the position of the graphic area, and the graphic area delimiter data is written only in the position corresponding to the boundary of the graphic area in the character text part. This solves the above problems.

(E) Effects In the present invention, when executing a document call, there is no need to manage graphic area numbers as in the past, and the simple task of rewriting the area definition data is sufficient.
Also, checking the size of the graphic area can be done by simply checking the area definition data.

(f) Embodiment The document shown in FIG. 6 was stored as shown in FIG. 7 in the conventional example, but in the present invention, it is stored as shown in FIG. 1.

That is, in this embodiment, as shown in FIG. 1, the graphic area delimiter data 14 is written in the character text section 5 only at positions corresponding to the vertical boundaries of the graphic area. 14 is not information specific to each graphic area, as in the past, but is used in common to all graphic areas simply as information indicating divisions between graphic areas, and is non-printed data displayed as ruled lines. be. That is, just as an indent mark is used as a document delimiter, the data 14 is used to indicate the delimitation of figures.

On the other hand, the graphic data section 6 is composed of a graphic element data storage area 16 of an area definition data storage area 15, and the graphic element data storage area 16 stores graphic element data for each graphic area as before. be done. The area definition data storage area 15 is an area for storing area definition data that defines the position of each graphic area in the document for each graphic area,
In this embodiment, the coordinates L of the row and column at the upper left end of the graphic area and the coordinates R of the row and column at the lower right end are paired as area definition data (L, R). Therefore, in the case of FIG. 1, (L1, R1) and (L2, R2) are stored in the area definition data storage area 15 corresponding to graphic areas 1 and 2, respectively.

Therefore, between figure area 1 and figure area 2,
When a document 18 having a graphic area 17 is called, in addition to writing the graphic element data of the new graphic area 17, the area definition data of the graphic area 2 is written to the graphic data section 6 (L2,
Process to change from R2) to (L4, R4) and area definition data of new graphic area 17 (L3, R3)
is added as data in the graphic area 3, but for the character text section 5,
There is no need for troublesome figure area number management; all you have to do is insert the data.

In addition, checking the size of the graphic area is as simple as checking the contents of the area definition data storage area 15, and the size check of the graphic area is as simple as checking the contents of the area definition data storage area 15.
There is no need to search for .

By the way, as shown in FIG. 3, the document having the above-described structure is stored in a document file 19 made up of a floppy disk, and in response to key input from the keyboard 20, characters are sent via the FDD 21. The contents of text section 5 are stored in text memory 2.
2, and the contents of the graphic data section 6 are read into the graphic data memory 23. Then, the character code in the text memory 22 is converted into a dot pattern by the character generator 24, and the
The content of the graphic data memory 23 is written into the RAM 25 and converted into a dot pattern representing a graphic by a calculation in the control unit 26.
5, and on the screen of CRT display 27,
Both patterns are displayed in combination.

In addition, inside the graphic area of the character text section 5,
It is also possible to write normal characters, in this case,
Text and graphics are displayed at the same time.

(G) Effects of the Invention According to the present invention, it becomes easy to check the size of a graphic area, and there is no need for troublesome graphic area number management when calling a document, thereby simplifying the system. Furthermore, it is possible to extremely easily display a composite display of graphics and characters within the graphics area.
