Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device, and more particularly to a document processing device that performs editing processing while displaying a document.

[Prior Art] Normally, when centering or right-justifying a string of characters on a line in a document, the procedure is to specify the target string by some means, and then press a centering key or right-aligning key. step on In this case, the character string to be centered or right-justified is often specified by moving the cursor to that line.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional document processing device,
For example, centering processing only involves actually bringing the character string to the center, and does not store any information indicating that that part has been (has been) centered.

Therefore, when re-editing a character string that has been centered by − degrees, a problem arises in that the character string must be specified after the editing process and the centering process must be performed again.

To explain using Figure 2, when centering the character string "About document editing," move the cursor to the line where the character string is located (state 200) and press the centering key etc. (state 2o1). After that, if the centered character string is edited <state 202), it is necessary to perform the process of centering (state 203) one last time.

The present invention has been made in view of this problem, and it is an object of the present invention to provide a document processing device that can efficiently perform processing by storing layout information for each line.

In addition to the above-mentioned object, the second invention aims to provide a document processing device that allows layout information of individual lines to be easily confirmed.

[Means for Solving the Problem] A document processing device of the first invention that solves this problem has the configuration shown below. That is, in a document processing device that edits and creates a document while displaying the document on a display screen, there is a storage means for storing layout information for each line in the document, and a predetermined editing process for the line of interest. When,
A display means is provided for displaying the layout of the edited line of interest based on the layout information stored in the storage means.

In addition to the above-described configuration, the second invention also includes mark display means for displaying a mark corresponding to the layout information stored in the storage means for each row displayed on the screen.

[Operation] In this first invention, when editing such as insertion or deletion is performed on a line, that line is displayed according to the layout information stored in the storage means.

Further, in the second invention, a mark corresponding to layout information set for each row is displayed for each corresponding row.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 is a CRT display unit using the Rusk scan display method; 2
is a video RA that can expand display pattern information for one screen.
M (VRAM), 3 is a display control unit that controls writing of pattern information into the VRAM 2 and reading out to the CR7 display unit 1.

4 is a microprocessor (MPU) that controls the entire device.
). 5 is a main memory that can be addressed by the MPU 4, and includes a ROM 5a that stores the operation processing procedure (program) of the MPU 4, and a RAM that is used as a work area and for storing document information being edited.
5b. Incidentally, the ROM 5a stores a program of a flowchart shown in FIG. 7, which will be described later. 6 is a hard disk device that stores document files, character fonts, and the like. 8 is a keyboard for inputting various commands and character strings to the device; 9 is a pointing device PD (such as a mouse) connected to the keyboard 8; Reference numeral 10 is a printer section for printing out edited documents, etc., and reference numeral 11 is a floppy disk device for storing document files. The hard disk drive 6 is used to store common documents, etc., and the floppy disk drive 11 is mainly for personal use.

Each of the above-mentioned components is connected via a system bus 7.

FIG. 3 shows the storage state of document information in the configuration of the embodiment described above.

In the embodiment, the document information being edited is divided into a text information area 30 that stores character codes, etc. included in the document information, and a line information area 31 that stores status information for each line of the document, as shown in the figure. It is separated into two parts. Of course, the text information area 30 also stores information such as the size of the output paper of the document, but since this is outside the scope of the present invention, it will not be described in detail.

As shown in the figure, the status information for the character string in one line in the line information area 31 includes the relative address 31a of the first character, alignment (right alignment or centering) information 31b, bullet point start position 31C, and page start line or end line information 31d. .

It consists of a homophone division flag 31e.

The relative address 31a of the first character is 1 if the first character of the line of interest is 1.
An address indicating the number of characters counted from the first character of the page is stored.

The alignment information 31b stores information indicating whether right alignment or centering is specified for the character string in the line of interest. The bullet point start position 31c stores information indicating from which character in the line of interest the bullet point starts.

In the page start line or end line information 31d, if the line of interest is the first line of the page or the last line of the page, a state to that effect is stored. This is to prepare for the case where the operator presses a key to force a page break at the line of interest even if the line of interest is a line in the middle of the set page.

Note that the line information is not limited to the information described above. The point is that it is sufficient if at least the matching information 31b is included.

Further, when a document is saved in the hard disk device 6 or floppy disk device, not only the text information area but also the line information area 31 is saved.

Next, an overview of the centering process in the embodiment will be explained using FIG. 4.

User C (a person who uses this device) moves the cursor to the line for which he wants to specify centering (state 4-1.4-2).

Thereafter, when the centering key is pressed on the keyboard 8, the character string in that line is shifted to the center, and data to that effect is stored in the shift information 31b in the corresponding line information. Then, the centering mark pattern stored in the ROM 5a is read out and displayed on the left side of the corresponding line (state 4-3). In addition, centering in the example is performed when the character string can be inserted to the true center position if the number of character insertable spaces for the line of interest (can characters be inserted later in that line) is an even number; In this case, the number of spaces located before the character string to be centered shall be one less than the number of spaces located after it.

In this way, the character string is centered. After this, for example, in state 4-3, when inserting the character string "processing" immediately after the character string "document editing", the following processing is performed.

First, if the number of inserted characters is smaller than the character insertable space of the line of interest, centering processing of the character string of interest including the inserted characters is sequentially performed.

State 4-4 in Figure 4 shows the state in which "processing" in the inserted character string "processing" has been inserted, and state 4-5 shows the state in which the next character "no" has been input. It shows. When the character "no" is input, the space available for character insertion is "1", so as shown in the figure, one blank space exists only on the right side of the character string. After this, the character string "Yose" is input, but at this point, the number of characters to be inserted exceeds the available space for character insertion, and lines are blurred. If the character insertable space reaches "0" (or less) due to the insertion of a character string in this way, the centering process becomes meaningless. Therefore, in this embodiment, in such a case, the display of the centering mark is stopped and
At the same time, the data indicating that the line of interest has been centered in the centering information 31b in the line information is cleared. A display example at this time is state 4-6. In addition, when simply clearing the alignment information 31b, by pressing a predetermined key provided on the keyboard 8, it is possible to return to the normal left alignment state.

Next, an outline of the operation of the right alignment process in the embodiment will be explained using FIG. 5.

First, the user moves the cursor to the line he wants to right-justify (state 5-1.5-2). Next, when the right alignment key is pressed on the keyboard 8, the character string in that line is shifted to the right end, and a mark indicating right alignment is displayed, as shown in state 5-3. At this time, information indicating that the line has been right-aligned is stored in the alignment information 31b for the line of interest.

After this, if you want to insert the character string "Processing Alignment" immediately after "Document Edit" in the right-justified character string, it will be as follows.

First, if the number of inserted characters is smaller than the space in which characters can be inserted in the line of interest, the character string of interest including the inserted characters is sequentially right-justified.

State 5-4 in Figure 5 shows the state in which "processing" in the inserted character string "processing" has been inserted, and state 5-5 shows the state in which the next character "no" has been input. It shows. After this, the character string "Yose" is input, but at this point, the number of characters to be inserted is greater than the space that can be inserted,
Lines are blurred. By inserting a character string like this, the available space for character insertion is “O” (or less)
If , the right alignment process becomes meaningless. Therefore, in this embodiment, in such a case, the display of the right alignment mark is stopped, and at the same time, the data indicating that the line has been right aligned is cleared in the alignment information 31b in the line information for the line of interest. A display example at this time is state 5-6.

If you try to insert a string after performing the centering and right-aligning processes described above, and the insertion point is outside the centered or right-aligned string, the alignment information for the line of interest will be cleared and not displayed. The centering mark and right alignment mark that were previously displayed will be deleted.

Figure 6 (A) shows an example where the character string rl/3J is inserted in the same line outside the centering character string "edit document", and Figure 6 (B) shows the same character string rl/3J outside the centering character string rl/3J. An example of inserting the character string "Document Edit" in a row is shown.

In both cases, it can be seen that the mark displayed before the insertion has been erased, and the alignment information 31b of the line information has been cleared.

The operation processing procedure of the MPU 4 for realizing the above-mentioned operation will be explained according to the flowchart of FIG. 7.

First, in step 57-1, when a character string is input from the keyboard 8, the alignment information 31b in the line information where the cursor was positioned at that time is checked to determine whether the line of interest is a centered line. (Step S7-2)
). If it is determined that the row is not a centering row, the process advances to step 57-9, and it is determined whether the row is a right-justified row. If it is determined that the line is not a right-aligned line, the process advances to step S7-13 and normal character insertion processing is executed.

Now, if it is determined in step 57-2 that the line of interest is a centering line, the process proceeds to step 57-3, and the processes described in states 4-3 to 4-6 in FIG. 4 are implemented.

First, in step 57-3, it is determined whether or not there is a space in which characters can be inserted in the line of interest. If it is determined that there is no space, the process proceeds to step S7-12, where the centering information in the centering information 31b is cleared (the displayed mark is also erased), and the process proceeds to step S7-13. If it is determined that there is a space in which characters can be inserted, the process proceeds to the next step 57-4, and it is determined whether the number of spaces is an odd number or an even number. Then, in each case, it is determined whether the number of characters input is an even number or an odd number (step 5).
7-5. S7-6). If the character insertable space is an even number and the number of input characters is odd, or if the character insertable space is an odd number and the number of input characters is an even number, in other words, when the number of input characters is inserted into the target character string. If it is determined that the character insertable space is an odd number, the process advances to step 57-7. Here, the number of spaces on the left of the entire character string of the line of interest (=old character string 10 input character strings) including the input character string is displayed in a format that is one less than the number of spaces on the right side of the character string. This process is performed when the character string in the line of interest cannot be brought to the true center. In addition, if it is determined that the space in which characters can be inserted in the entire line of strings including the input string is an even number, the process proceeds to step 57-8, and the character located at the center of the string is inserted into the line. Center and display.

Now, if it is determined that the line of interest is a right-justified line, the process proceeds from step 57-9 to step S7-10, and the fifth
The processes described in states 5-3 to 5-6 in the figure are realized.

First, in step S7-10, it is determined whether or not a character insertable space will occur when the input character string is inserted into the line of interest. If it is determined that there is no such space, the process advances to step S7-12. If it is determined that there is a space, the process proceeds to step S7-11, where the character string before the cursor at that time is moved to the space between the input characters, and the input character string is set in the empty area. Although not specifically explained in the above processing, if step S is provided to determine whether the insertion position (cursor position) of the input character is outside the character string of the line of interest, the determination The processing is performed between step 57-2 and step 57-3 and between step 57-9 and step S7-1.
It is sufficient to position it between 0 and 0. If it is determined that the cursor is located outside the position, step S7
-12, and if it is determined that the cursor is located within the character string of the line of interest, the process may proceed to step 57-3 or step S7-10.

In the above-described embodiment, a case has been described in which several characters can be input at a time, for example, in a kana-kanji conversion process. However, 1
In a type of document processing device that inputs characters one by one and then centers or right-aligns the input, the processing becomes easier.

For example, if the determination in step 57-4 is YES, that is, if it is determined that the character insertable space for the line of interest before insertion is an odd number, the character string after the cursor is moved to a one-character distribution, Insert the input character into the empty space. Furthermore, in the case of NO, the character string before the cursor may be moved one character in between, and the one character inputted may be inserted into the empty space.

As explained above, according to this embodiment, even if editing is performed on a character string in a line that has been centered or right-justified, the edited character string is displayed according to the layout information set for that line. , can provide an efficient editing environment.

Furthermore, it is convenient to display the layout status of each line (right alignment, centering, etc.) for each line, as this can be used as a reference when editing. At this time, if no mark is displayed, it can be determined that the line is in normal mode.

Note that although the editing process in the embodiment has mainly been explained using insertion of character strings as an example, it goes without saying that deletion or the like may also be performed.

[Effects of the Invention] As explained above, according to the present invention, even if a character string in a line is edited, the edited character string is displayed according to the layout information set for that line. It can provide an efficient editing environment.

Furthermore, it is convenient to display the layout status of each line (right alignment, centering, etc.) for each line, as this can be used as a reference when editing.
