Abstract

PURPOSE:To enable a document to be processed without disturbing document text data in other columns or breaking the form of a table, by providing a means for recognizing a table part in the document text data, a means for registering columns in the table thus recognized, and a means for editing with each of the registered columns as a unit. CONSTITUTION:A document text inputted by a word processor is read from a floppy disk device 11 into a document text storage area TXT in a main memory 5 on a page-by-page basis. To process a table part, frames of a table are first retrieved, and vertical ruled lines contained in candidates for the frames of the table are registered into a vertical ruled line table CTB in the main memory 5. A similar processing is applied to horizontal ruled lines, thereby registering the horizontal ruled lines into a horizontal ruled line table RTB in the main memory 5. It is checked whether all regions bounded by the ruled lines in the frame of the table are rectangular, based on the ruled line tables CTB, RTB in which the ruled lines are registered. Finally, cell data are registered. The table part of the document text is recognized as a table, and information on the ruled lines and information on cells are entirely registered in the tables CTB, RTB, CELL.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device having a function of typesetting a document.

[Prior Art] Conventionally, when creating a document using a simple document processing device called a word processor, the characters had a fixed pitch and lacked aesthetic appeal, but the operation was relatively simple. On the other hand, a document processing device having a typesetting function as defined in the present invention can change the character pitch and the size of each character, so it is possible to output a visually beautiful document. , the operation was relatively remote. Therefore, there is a need for a document inputted by the 2-1 processor to be subjected to typesetting processing by the document processing device according to the present invention, and then output.

[Problems to be Solved by the Invention] However, if a document created with a word processor has tables, the format of this document data should not be destroyed, but it is difficult to convert the document created with a word processor into a conventional document processing device. , even if there is a table in this document, the table is not treated as a table, and if you edit the document data in the table column, the appearance of the table will be corrupted.

[Means for solving the problem] In order to solve this problem, the present invention provides a recognition means for recognizing the front part of input document data, a registration means for registering the recognized front fence, and means for editing each registered field.

[Function] The columns of the table recognized by the recognition means are registered and edited column by column, so document processing can be performed without disturbing the document data in other columns or destroying the appearance of the table. It can be carried out.

For example, when the first cell is designated as the first column using the pointing device 9, the character string contained in this first cell is obtained via the pointer to the character string in the cell table CELL.

This character string can be edited in the same way as normal typesetting processing. However, by processing in this case, this character string will not be affected outside the column defined by the upper left X coordinate, upper left y coordinate, lower right X coordinate, and lower right y coordinate in the cell table CELL. .

[Embodiment] Hereinafter, one embodiment suitable for the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system block diagram of a sentence B processing device according to an embodiment of the present invention.

In the figure, 1 is C used in the Rusk scan display method.

A, a storage area TXT for storing document data, a table area for storing data related to tables, CTB, and RTB.

4 is a main memory having CELL, and 4 is a microprocessor (MPU), which performs main control of this device. The MPU 4 includes a keyboard 8 for inputting character data, etc., and a CRT.
A pointing device (PD
) 9 is sold as a glue. 6 is a hard disk device in which document files and character fonts are stored. 10
1 is a printer for outputting created documents, and 11 is a floppy disk device for inputting floppy documents created by a word processor. Each of these constituent blocks is connected by an I10 bus 7.

In the following, a case will be explained in which a document created with a word processor and having a table as shown in FIG. 9 is handled.

Documents input using a word processor are transferred one page at a time from the floppy disk device 11 to the document storage area T of the main memory 5.
Loaded into XT. At this time, the ruled lines of the text as shown in Figure 9 are generally JISC62 as shown in Figure 2.
It is represented by 26 ruled line segment codes. FIG. 3 is an exploded view of the ruled line portion of FIG. 9 so as to identify the type of the corresponding ruled line segment code.

Next, processing related to the table portion will be explained with reference to FIG.

First, in step 6-1, a table frame is searched.

This is the first process to determine the parts of the table, searching for the outermost frame of the table. Specifically, the process in FIG. 4 ends as if the page is not at the top of the page.

If found (5-1 in Figure 3), 1 in order from there.
Check each letter one by one.

Check each character one by one. Permissible codes are checked in the same manner as in steps 5-3, 5-4 and back to 5-1 in FIG. When this check is completed, the portion surrounded by the checked area is recognized as a table frame candidate, and the process moves to step 6-2.

In step 6-2, the vertical ruled lines included in the best table candidates are registered in the vertical ruled line table CTB in the main memory 5. The details of this vertical ruled line table LTB are shown in FIG. As a general rule, the registration method considers connected vertical ruled lines as one tree.
If it intersects with a horizontal ruled line, cut it there and register the top and bottom as separate ruled lines. In Figure 3, from 5-a to 5-
Nine trees of h will be registered. Specifically, if there is a ruled line segment code that includes a vertical ruled line, it is first registered in the table. At this time J (815).

When there are L (8/6) and 2 (8/10), the vertical ruled line ends there, so the X coordinate and the top and bottom edges (7)
The y coordinate is not registered here.

(In the case of G (8/7), @ (8/9), and M (8/11), one tree of vertical ruled lines will be registered, and in addition, the undefined ruled line at the bottom will be registered.) Bottom edge When a ruled line is registered that is not fixed, register the ruled line in the vertical ruled line table while typing, and
), the processing for this column ends. The process ends in the same manner.

In step 6-3, similar processing is performed for horizontal ruled lines,
It is registered in the horizontal ruled line table RTB in the main memory 5.

In the process of step 6-2.6-3 above, the attributes of the ruled lines in the ruled line table are all front ruled lines, but of course if a ruled line segment code other than that shown in Figure 2 is used, the ruled line according to it will be attributes will be registered.

In step 6-4, based on the ruled line tables CTB and RTB registered in this way, it is checked whether all areas delimited by ruled lines within the frame of the table are rectangular. First, one vertical ruled line is obtained one by one from the vertical ruled line table CTB, the connections with other vertical ruled lines are checked, and the connected lines are considered to be one tree in this case, and both ends of the vertical ruled lines are found. Next, it is checked in the horizontal ruled line table RTB whether or not there are two horizontal ruled lines having each of these endpoints as an endpoint. If there are not two, check whether it is the point 5-1.5-2.5-3.5-4 in Figure 3. If not, there is a non-rectangular area, so use the points in this table. As for the frame candidate, it is determined that J is not the front, and the processing in FIG. 6 is terminated. In the same way, all the ruled lines registered in the vertical ruled line table CTB are checked, and when the check is finished, the ruled lines are sequentially retrieved one by one from the horizontal ruled line table RTB and the same check is performed. Once the above checks are completed, all parts of the table frame separated by ruled lines can be considered to be rectangles.

Finally, the cell data is registered in step 6-5. This process sequentially fetches one ruled line from the horizontal ruled line table RTB, searches the vertical ruled line table CTB for a vertical ruled line extending below each end of the ruled line, and
If not, there should be a horizontal ruled line that connects to that contact point,
This is searched from the horizontal ruled line table RTB, and the vertical ruled line extending below the end point is searched again, considering it as one line along with the original ruled line. If there is a vertical ruled line, it becomes the edge of the cell. In this way, the left and right ends of the cell are determined, and then the bottom end of the cell is determined based on 10,000 vertical ruled lines on either the left or right end. This is taken as the lower end and end point of the vertical ruled line, and a horizontal ruled line extending in the direction of the original horizontal ruled line is searched from the horizontal ruled line table RTB, and if found, that position is the lower end of the cell. If not, there must be a vertical ruled line whose upper end point is that end point, and the ruled line table CTB is searched for it, and the horizontal ruled line table RTB is similarly searched for the lower end point. By repeating the above steps, the lower end of the cell is determined.

Once the range of the cell is determined, it is registered in the upper left X coordinate, y coordinate, and lower right X coordinate, y coordinate of the cell table CELL in the main memory 5, and then based on that range, the data contained in the cell is Determine the character string, store the character string separately, and store the pointer to the character string in the cell table CE.
LL! , : Wet. Details of the cell table CELL are shown in FIG. 5(b). The above processing is performed using the horizontal ruled line table RT.
By doing this for areas other than the horizontal ruled lines that make up part 5-3 from 5-4 in B, all the cells in this table will be as shown in Figure 5 (
As shown in b), the character strings registered in the cell table CELL and contained within the cell are also determined.

With this, the processing in Figure 4 is completed, the table part of the document in Figure 9 is recognized as a table, and all information regarding its ruled lines and information regarding cells are stored in the tables CTB, RTB, and CE in Figure 5.
Registered in LL.

Therefore, from now on, the main text of this document will be typewritten with the table frame part as a prohibited area, and the table part will be created with ruled lines from tables CTB and RTB in Figure 5, and the characters in each cell will be typewritten using the cell table. If typesetting is performed within the cell based on the CELL information, the formatted state will be output while maintaining the table format as shown in FIG. 6.

In this way, a document created such that the outer frame of the table as shown in FIG. 9 is rectangular, and the areas delimited by internal ruled lines are all rectangular, can be used as is.

Next, a case will be explained in which a table created in an incomplete form as shown in FIG. 7 is handled. It can be determined that such a document is not a complete table when it is checked in step 6-4 in the process shown in FIG. 4 that all areas formed by ruled lines are rectangular. In such a case, that page of the document is then displayed on the CRTI at a fixed pitch similar to how it is displayed on a word processor. The operator then operates the pointing device 9 to add or delete ruled lines on the CRTI to create a complete table. Specifically, when adding a ruled line, instructions are given for both ends of the ruled line to be added, and when the instructions are given, the device first determines whether to add a vertical ruled line or a horizontal ruled line from those coordinates. If you want to add a vertical ruled line, extract all the vertical ruled lines connected to it from the vertical ruled line table CTB, set it as one tree, then search the horizontal ruled line that intersects with that ruled line from the horizontal ruled line table RTB, and then add the created vertical ruled line. Split vertically ruled table CTB! ,:register. Add horizontal ruled lines in the same way.

When deleting a ruled line, specify the point on the ruled line to be deleted, and the device stores the specified ruled line from the coordinates in the ruled line tables CTB and RTB.
Search and delete. If it is a vertical ruled line that has been deleted, extract all the horizontal ruled lines that intersected that vertical ruled line from the horizontal ruled line table RTB, convert the connected ones to books, and then search the vertical ruled line table CTB again and divide them. Perform the processing to register it again in the table. Once you have finished adding and deleting ruled lines as described above, repeat step 6-4 in Figure 4.
With further processing, a document with a table as shown in FIG. 7 can also be output as shown in FIG. 6.

Furthermore, a case will be explained in which a document having a table without ruled lines as shown in FIG. 8 is handled.

In the process of FIG. 4, such a document is processed as if it does not have a table in the process of step 6-1.

Therefore, in this case, the operator instructs that this page be displayed in the same manner as in a word processor, and uses the pointing device 9 to designate the table frame by indicating its upper left and lower right points. In the following, the process of adding and deleting ruled lines may be performed in the same manner as in the case of FIG. In this way, a table without ruled lines as shown in FIG. 8 can be output as shown in FIG. 6.

And table CT B as shown in FIG.

Since it is RTB, in addition to obtaining the output shown in Figure 6, you can also specify the attributes of the ruled line and change the type of ruled line to back ruled, etc. You can easily change the font size and font, or set it to vertical writing, and you can also save it in that state.

In other words, by treating the frame defined by the cell table CELL as one column, you can maintain the table format of a document created with a fixed pitch using a word processor, etc.
Can edit and format documents.

[Effect] As described above, according to the present invention, the column! It is possible to provide a document processing device in which characters can be edited and corrected at # position without affecting the margins or other columns.
