Abstract

PURPOSE:To extract a heading matched with a format without specifying a heading character string at the time of preparing a document by making it possible to specify the format of a heading. CONSTITUTION:When a heading setting key on a keyboard KB is depressed in the case of registering the setting of a heading format, a heading setting table display screen is displayed. When a heading candidate table key is depressed, a heading candidate table screen showing heading formats is displayed. At the time of moving a cursor to a number corresponding to a required candidate, the position of the cursor is held in the CURKY of a RAM. When a setting register key is depressed, a heading level input screen is displayed, and when a heading level is inputted by a number key, the character string is shifted down by the specified level and registered. Thus, the heading format can be specified, and even when a heading character string is not accurately specified at the time of preparing a document, a heading matched with the format can be extracted from a composed sentence.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that handles document constituent elements such as titles, headings, paragraphs, sentences, figures, and pictures.

[Prior Art] Generally, in the above-mentioned character processing device, the title and
Headings and their equivalents must be specified.

Conventionally, these specifications have been performed as follows.

- Write headings in a dedicated area separate from the document area.

・Write a heading in the document area and add special symbols such as a heading symbol.

・Write a heading in the document area and give the indentation position of the heading.

However, the above conventional example has the following problems.

(1) Headings must be specified at the same time as document creation.

(2) Documents that have already been created cannot be processed as they are.

(3) Indentation and other settings are independent of the heading format, and may be processed incorrectly.

Also, even though it is simply a heading, there is a hierarchy (level), so it was necessary to specify that as well. For example, a major headline,
The heading level for medium headings and subheadings must be specified. When adding levels to headings, the level is generally indicated by indentation.

For this reason, conventionally, the level was specified by specifying the digit position of the document area. For example, a designation such as ``Main headings, medium headings, and subheadings start from the 1st, 3rd, and 5th digits, respectively'' was specified.

Moreover, even if the headings were set with great difficulty as described above, the format of the headings could not be saved.

[Objective] In view of the above points, an object of the present invention is to provide a document processing device that can specify a heading format and accurately extract a heading that matches the format without specifying a heading character string when creating a document. It is about providing.

In view of the above points, an object of the present invention is to provide a character processing device that can display each heading according to the level by setting the level of the heading.

In view of the above points, an object of the present invention is to provide a character processing device that can easily specify and save the format of a heading.

FIG. 20 is a diagram showing the structure of the heading candidate table (MDKTBL) in the present invention on the RAM shown in FIG. 1.

MDKNF sets the heading candidate number to 1 in the heading candidate number section.
Store in bytes. MDKNF(i) is the i-th heading candidate number section from the top of the table, and the content is i.

MDKHF is a heading candidate display data section that stores up to 20 display characters (each character is 2 bytes). The JIS C-6226 code is used as the code, and the remaining space is filled in with character codes for spaces. MDKHF (i
) is the display data section of the i-th heading candidate from the top of the table.

MDKSF is a leading character section for determining a heading, and stores up to 10 leading characters for determining a heading, each character being 2 bytes. The code uses JIS C-6226 code.

In addition to the JIS C-6226 code, the code is
It may store the following code defined by itself.

01 (code representing character codes of numbers from 0 to 9) 02 (code representing all characters) 03 (heading symbol code) MDKSF (i) is the header for determining the heading of the i-th heading candidate from the top of the table This is the character part.

MDKEF is a final character section for determining a headline, and stores the final character for determining a headline in 2 bytes per character. The code is JI
Uses SC-6226 code. If there is no heading determining sentence ending character, 02 (a code representing all character codes) is stored. EF(i) in MD is the last character part for heading determination of the i-th heading candidate from the top of the table.

FIG. 21 is a diagram showing the configuration of the heading setting table (MDSTTBL) on the RAM shown in FIG. 1.

MDSKHF is a heading candidate number field, and stores a heading candidate number for which a heading has been set in one byte. MDKH
F(i) is the headline candidate number part of the i-th headline setting data from the top of the table.

MDSLNF is a heading level number section and stores the heading level number in 1 byte. The level number of a heading is a positive integer, and the smaller the number, the higher the level of the heading. MDSLNF (i) is the heading level number part of the i-th heading setting data from the top of the table.

Figure 22 shows the document buffer TB on the RAM shown in Figure 1.
FIG. 2 is a diagram showing the structure of document data stored in a UF.

(a) shows that TBUF is stored divided into several row data. Document coordinates are assigned to each line of data, and for example, when specifying the first line of data, the Y coordinate of the document coordinates, y=i, is set.

The length of each row data is fixed, and each row consists of 128 bytes.

(b) is a diagram showing the structure of each row of data. The line data consists of 64 character data.

Document coordinates are assigned to each character data, and for example, when specifying data for the first character, the X coordinate of the document coordinates is set to x=1. The length of each character data is fixed, and each character consists of 2 bytes.

The JIS C-6226 code is used for character data, and areas where no characters are stored in the document data are filled with 0's. In addition to the JIS C-6226 code, a self-defined heading symbol code (03) is also used. A heading symbol is a symbol that an operator writes at the beginning of a string of characters that he or she wants to use as a heading.

The operation of the above embodiment will be explained according to the flow.

FIG. 23 is a flowchart showing the operation of the character processing device of the present invention. In step 23-1, a key is pressed on the keyboard and a wait is made for an interrupt to occur. When a key is input, step 23-2 branches to one of steps 23-3, 23, 4, and 23-5 depending on the type of key.

Step 23-3 is a process performed when the heading setting key is pressed, and sets the format of the heading to be displayed as a heading.

Step 23-4 is a process performed when the heading display key is pressed manually, and a character string as a heading is extracted from the document in the document buffer and displayed.

Step 23-5 is a process that is performed when normal keys other than the heading setting key and the heading display key (for example, character keys and cursor movement keys) are manually operated, and is a process that is generally performed in character processing devices of the same type. Since it is well known, it will not be specifically described.

FIG. 24 is a detailed flowchart of the heading setting process (step 23-3 in FIG. 23) according to the present invention.

Step 24-1 is a heading setting table list display process. All the headings set in the heading setting table are displayed here.

That is, the first heading setting data to the MDSTMAXth heading setting data of the heading setting table are displayed. 2.6,10゜11.12,14,15,
Display as shown in Figures 16, 17, and 18.

The first heading setting data in 524-1 described above is displayed as follows.

MDSKHF If the content of (i) is X, then MDKHF
Display (x) from MDSLNF (i)th digit. In other words, it is displayed indented according to the level of the heading (
For example, Fig. 11).

You can also use a window to display it at the same time as the document. Display is a commonly used process of reading data, developing it into a pattern, and outputting it to a display buffer.

Step 24-2 is a key human power determination process.

When the heading candidate view key is input, the process advances to step 24-3.

When the heading setting deletion key is input, the process advances to step 24-7.

When the heading setting save key is pressed manually, the process advances to step 24-9.

When the heading setting call key is pressed manually, the process advances to step 24-10.

When the heading setting end key is input, the heading setting process is ended.

If a key other than the above is input, that key is ignored and the key human power determination process is performed again.

Step 24-3 is a heading candidate list display process.

Here, all heading candidates set in the heading candidate table are displayed (FIGS. 3 and 7). That is,
MDKM from the first heading candidate in the heading candidate table
Display up to the AXth heading candidate. The i-th heading candidate only displays MDKHF (i).

Step 24-4 is a heading setting designation process. The operator specifies the heading to be registered from the list of heading candidates displayed in step 24-3 (Figs. 4 and 8).
figure). When the operator moves the cursor to the relevant heading and inputs the heading setting registration key, the process proceeds to the next step. When the cursor is moved, the CU
Although the RKY value is rewritten, this process is commonly performed in character processing devices of the same type and is well known, so it will not be described in particular.

Step 24-5 is heading level manual processing. "
The message "Please enter the level of the heading" will be displayed and the system will wait for key input. When a numeric key is input, the process advances to the next step (FIGS. 5 and 9).

Step 24-6 is a heading setting registration process. Cursor position (CURKY) specified in step 23-4
Based on the heading level input in step 24-5, the heading setting table (MDSTTBL, FIG. 21) is created.
Register. Data is registered in the heading setting table so that data is stored in ascending order of heading level. The value of MDSTMAX is increased by 1 if registered. When registration is completed, the process proceeds to the next step. Proceed to step 24-11 and erase the windows and messages displayed in steps 24-1.24-3.24-4.24-5. Next, the process proceeds to step 24-1 1. After registration, the heading setting table-list display process is performed (Figure 6.10.11).

Step 24-7 is a heading deletion designation process. From the heading setting table displayed in step 24-1,
Let the operator specify the headings to be deleted. When the operator moves the cursor to the relevant heading and presses the heading setting/delete key, the process proceeds to the next step. When the cursor is moved, the value of CURSY is simultaneously rewritten, but this process is commonly performed in character processing devices of the same type and is well known, so it will not be described in particular.

Step 24-8 is a heading setting deletion process. Cursor position (CURSY) specified in step 24-7
is deleted from the heading setting table (MDSTTBL) based on. The heading setting table after deletion is packed so that there is no empty space in the heading setting data. Furthermore, when the data is deleted, the value of MDSTMAX is subtracted. Next, the process proceeds to step 24-11, the window displayed in step 24-1 is erased, and the process proceeds to step 24-1. Here, a list display process of the heading setting table after deletion is performed (FIG. 14).

Step 24-9 is a heading setting saving process. Here, the heading setting table (MDSTTBL) is saved in the external storage device (DISK). When the saving is completed, a message is displayed (Fig. 16). After a few seconds, the process proceeds to step 24-11, and then steps 24-1 and 24-9.
Delete the window and message displayed in step 2.
Proceed to step 4-1.

Step 24-10 is a heading setting call process.

Here, the heading setting data stored in the external storage device (D)SK) is stored in the heading setting table (MDSTTB).
Call L). When the call is completed, a message is displayed (Fig. 18). After a few seconds, step 24-1
The process proceeds to step 1, the window and message displayed in step 24-124-10 are erased, and the process proceeds to step 24-1.

FIG. 25 shows the heading display process (step 2) in the present invention.
3-4) is a detailed flowchart. The heading display process is a process of determining whether or not each line of document data is set in the heading setting table, and if so, displaying that line.

Step 25-1 is initial setting processing.

j is a variable that stores the processing status of document data, and its initial value is 1.
Substitute. This means that the first line of the document is processed first.

Step 25-2 is a heading check initial setting process. i is a variable that stores the position of the heading setting data being processed, and 1 is assigned to its initial value. This means that the first heading setting data is processed first. (Figure 21, data at the head of the heading setting table) Step 25-3 is a heading head check process. The first character of the first line of the document and the data registered in the i-th position of the heading setting data (CMDSKHF (i))
Checks whether the first character for determining the heading in the heading candidate table pointed to matches. That is, it is determined whether the beginning of the first line of the document (other than spaces) matches MDKSF (MDSKHF(i).), which is the first character for determining the heading. In this way, for example, as shown in Figure 6, if you set nn...° to be used as headings, 1-2° and ° at the beginning of each line in the document
Character strings starting with 1-3° etc. can be headings. Here, "Ol" means a number, such as "1" or r262
69J, etc. "02" means a character and can match any character.

"03" is the heading symbol mentioned above, and is also a symbol that exists in the document. This is treated in the same way as ordinary characters. This is because the heading symbol can be substituted into the document by pressing the "heading symbol key" in the same way as general characters during document editing.

If they match, the process advances to step 25-4. If they do not match, the process advances to 25-6.

Step 25-4 is a heading end character check.

It is determined whether or not the last character (other than a space) of the j-th line of the document matches the heading determination ending character of the heading candidate table pointed to by the data registered in the i-th heading setting data. Determination of match is step 25-3
This is the same process as . That is, it is determined whether the last character (other than a space) of the j-th line of the document matches MDKEF (MDSKHF(i)), which is the last character for determining the heading.

In this way, for example, as shown in Figure 10, if you set the heading ``[heading enclosed in brackets]'' to be used as a heading, you can create a text such as The character string surrounded by [ ] becomes a heading, and is displayed in step 25-5. In addition, even if there is no binding such as the nn format, the data "02" shown in Figure 20
If exists, a match is determined in 525-4.

If they match, the process advances to step 25-5. If they do not match, the process advances to step 25-6.

Step 25-5 is a heading line display process. This process creates and displays display data as follows.

First, from the document line (j) being processed, the number of pages on which that line exists and the number of lines within that page are determined. The number of pages is (j-1) -
It is the quotient divided by the number of lines per page plus 1, and the number of lines within a page is the remainder of (j - 1) divided by - the number of lines per page plus 1. The display data is "number of pages",
It consists of "number of lines" and "character string existing in line j of the document", but between "number of lines" and "character string existing in line j of the document" there is a heading level number + 1 ( MDSLNF
Insert space for (i)+1). This is for indenting depending on the level of the heading.

Step 25-6 is a heading setting next data setting process. Increase i by one and update the processing position of the heading setting data.

Step 25-7 is a heading setting number check process. Determine whether there is heading configuration data to process. When i≦MDSTMAX holds true, heading setting data exists. If it exists, the process advances to step 25-3. If it does not exist, the process advances to step 25-8.

Step 25-8 is a document data processing waiting update process. Increment j by one and update the queue to be processed to the next line.

Step 25-9 is a document line check process. Determine whether a document exists in the j-th line of the document data.

When j≦TBUFLMAX holds true, document data exists in the j-th line. If the document exists, the process advances to step 25-2. If it does not exist, the process ends. At the end of the process, the screen displays all of the headings displayed in step 25-2 (FIG. 19).

[Effects of the Invention] As detailed above, according to the present invention, a heading format can be specified, and a heading that matches the format can be created from a created document without having to specify a heading character string accurately at the time of document creation. It has become possible to provide a character processing device that can extract .

As described above in detail, the present invention makes it possible to provide a character processing device that can display each heading according to its level by setting the level of the heading.

As described above in detail, the present invention makes it possible to provide a character processing device that can easily specify the format of headings and can also save them.
