Abstract

PURPOSE:To facilitate the processing of a table part by registering the table part to perform a composition processing while keeping the show of the table when the table generated by a word processor is inputted. CONSTITUTION:The document inputted by the work processor is read into the document storage area TXT of a main memory 5 from a floppy disk device 11 page by page. The frame of the table is first retrieved, and vertical rules included in the candidates of the frame of the table are registered in the vertical rule table CTB of the main memory 5, and the similar processing is performed for horizontal rules, and they are registered in the horizontal rule table RTB of the main memory 5. It is checked whether areas divided by rules in the frame of the table are all rectangular or not based on the contents of rule tables CTB and RTB, and finally, cell data are registered. Thus, the table part of the document is recognized as a table, and the justification and composition of the following text part of the document are performed with the frame part of the table as an inhibiting region.

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 a word processor to be formatted and outputted by a document processing device as defined in the present invention.

[Problem to be solved by the invention] However, if a document created with a word processor has a table, the format of this document data should not be destroyed, but it is difficult to process the document created with a word processor using conventional document processing. When read into a device, even if there is a table in this document, the table is not treated as a table, and the ruled lines that make up the table are also treated simply as character data. There was a downside to it being destroyed.

[Means for Solving the Problem] After solving this problem, the present invention provides a means for recognizing a table part of an input document, a means for registering the recognized table part, and a means for registering the recognized table part. and a means for performing typesetting processing while maintaining the appearance of the table portion.

[Operation] Recognized tables can be registered and typesetting processing can be performed while maintaining the appearance of the registered tables.

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

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 sentences such as the 9th ward 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 that the type of the corresponding ruled line segment code can be seen.

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 section in FIG. 4 ends as if it were 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.

Start testing r-(8/3) again from the section.

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 one is added to the processing in step 6-2.

In step 6-2, the vertical ruled lines included in the table frame candidates are registered in the vertical ruled line table CTB in the main memory S. The details of this 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 books 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 is '-(a/6)-2(8/10), the vertical ruled line ends there, so the X coordinate and the X coordinates of the upper and lower ends are not registered here.

Undefined ruled lines will be registered. ) When a ruled line with an undefined bottom edge is registered, register the ruled line in the vertical ruled line table while performing text printing, and the result will be 8/6)
When the column (5-4) is reached, processing for this column is terminated. 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 coat other than that shown in Figure 2 is used, the ruled lines according to that 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, bring one vertical ruled line to the head of the vertical ruled line table CTB, check the connections with other vertical ruled lines, and find both ends of the vertical ruled lines, considering that the connected lines are one tree here. Next, it is checked in the horizontal ruled line table RTB for each of these two endpoints whether there are two horizontal ruled lines having the endpoint as the 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 candidates, it is assumed that they are not tables, 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! 8. In order to obtain a ruled line one by one from the horizontal ruled line table RTB, search the vertical ruled line table CTB for a vertical ruled line that extends below each end of the ruled line, and if not, find a horizontal ruled line that connects to that border. There should be a ruled line, so it is searched for from the horizontal ruled line table RTB, considered to be one tree along with the original ruled line, and the vertical ruled line extending below the end point is searched again. 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 the vertical ruled line at 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 top end point is that end point, and the vertical ruled line table CTB is searched for it, and the horizontal ruled line table RTB is similarly searched for its bottom point.

By repeating the above steps, the lower end of the cell is determined.

Once the cell range is determined, it is registered in the upper left X coordinate, X coordinate, lower right X coordinate, and X coordinate of the cell table CELL in the main memory 5, and then based on that range, Determine the character string, store the character string separately, and store the pointer to the character string in the cell table CE.
LL! , : Noboru! Do 3. Details of the cell table CELL are shown in FIG. 5(b). By performing the above process for the horizontal ruled lines other than those forming the 111 parts from 5-1 to 5-3 in the 1-ruled line table RTB, all the cells in this table are shown in Figure 5(b). is registered in the cell table CELL, and the character string to be included in the cell is also determined.

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

Therefore, from now on, in this document, the text part will be edited 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 If typesetting is performed within the cell based on the i-brochure of the cell table CELL, 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 is rectangular as shown in FIG. 9 and the areas delimited by internal ruled lines are all rectangular can be used as is.

Next, I will explain the gift that deals with tables created in an incomplete form as shown in the seventh blade. Such documents are marked 1. with the ruled lines in step 6-4 in the process of FIG. °4 When checking that all the areas created are rectangular, it can be determined that the table is not a complete table. 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, specify both ends of the ruled line to be added, and when the instruction is given, the device first determines from those coordinates whether it is a vertical ruled line or a horizontal ruled line. If you want to add a vertical ruled line, take out all the connected ruled lines from the 5-line border table CTB and set them as one tree, then search the horizontal ruled line table RTB for the horizontal ruled line that intersects with that ruled line,
Separate the vertical ruled lines created by this and create a vertical ruled line table C.
Register on TB. 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 with that vertical ruled line from the horizontal ruled line table RTB, convert the connected ones into books, and then search the vertical ruled line table CTB again and divide them. Process and re-register in the table. When the addition and deletion of ruled lines is completed as described above, by repeating the process from step 6-4 in FIG. 4, text having a table as shown in FIG. 7 can be outputted as shown in FIG. 6.

Further, a case will be described in which a document having a table without ruled lines 42 as shown in FIG. 8 is handled.

In the process shown in FIG. 4, such a document is rejected in step 6-1 as having no front page.

Therefore, in this case, the operator instructs to display this page in the same manner as a word processor, and uses the pointing device 9 to designate the frame of the table 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 CTB as shown in FIG.

Because it is RTB, in addition to obtaining the pressure 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., or make sure that the ruled line is not printed. 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, when a table created with a word processor is input into the document processing device of the present invention;
Since the front part is registered and typesetting processing is performed while maintaining the front appearance, the front part can be easily edited.
