Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus and method, and more particularly to a document processing apparatus and method for editing a document.

[Related Art] Normally, when a character string on a certain line in a document is to be centered (centered) or right-justified, a target character string is specified by some means, and a centering key or a right-aligning key is pressed. Step on. In this case, the character string to be centered or right-justified is often specified by moving the cursor to the line.

[Problems to be Solved by the Invention] However, in the above-described conventional document processing apparatus, for example, the centering process is started only by actually bringing the character string to the center, and the place is centered (performed). Is not stored together.

Therefore, when re-editing a character string once centered, there arises a problem that the character string must be specified after the editing processing and the centering processing must be performed again.

Referring to FIG. 2, when centering a character string of "document editing", the cursor is moved to a line where the character string is located (state 200), and the centering is performed by pressing a centering key or the like. Is performed (state 201). Thereafter, when the centered character string is edited (state 202), it is necessary to finally perform another process of centering (state 203).

The present invention has been made in view of such a problem, and when the character insertion space becomes 0 and the layout set for each line becomes meaningless, the set layout information is released. An object of the present invention is to provide a document processing apparatus and method which eliminates the need to continue unnecessary layout processing and improves processing efficiency.

[Means for Solving the Problems] To solve the problems, for example, a document processing apparatus of the present invention has the following configuration. A storage unit for storing layout information for each line in the document; and a character that has already been laid out and displayed according to the layout information stored in the storage unit for the line of interest in which the character has been input. Output control means for laying out and outputting the entire character of the line of interest including the selected character; insertable space determination means for determining whether the character insertable space of the line of interest has reached 0; When the space discriminating means determines that the insertable space of the line of interest has reached 0, there is provided a setting canceling unit for canceling the layout information of the line of interest in the storage unit.

Embodiment An embodiment according to the present invention will be described below in detail with reference to the accompanying drawings.

It is composed of a ROM 5a and a RAM 5b used as a work area or for storing document information being edited. The ROM 5a stores a flowchart program shown in FIG. 7, which will be described later. Reference numeral 6 denotes a hard disk device that stores a document file, a character font, and the like. Reference numeral 8 denotes a keyboard for inputting various commands and character strings to the apparatus, and 9 denotes a pointing device PD (mouse or the like) connected to the keyboard 8. Reference numeral 10 denotes a printer unit for printing out an edited document or the like, and reference numeral 11 denotes a floppy disk device for storing a document file. The hard disk device 6 is used for storing common documents and the like, and the floppy disk device 11 is mainly for personal use. The components described above are connected via a system bus 7.

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

In the embodiment, the document information being edited includes a text information area 30 storing character codes and the like included in the document information and a line information area 31 storing state information for each line of the document as shown in the figure. Are separated into two. Of course,
The text information area 30 also stores information such as the output paper size of the document, but this is outside the scope of the present invention and 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 is the relative address 31e of the first character, the justification (right alignment or centering) information 31b, the itemized start position 31c, the page start line or end line information. 31
d, a homophone division flag 31e.

For the relative address 31a of the first character, the first character of the line of interest is 1
An address indicating the number of the character 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 of the line of interest. The item start position 31c stores information indicating from which character of the line of interest the item starts at the item. The page start line or end line information 31d stores a state indicating that the line of interest is the first line of the page, the last line of the page, or the like. Note that this is for the case where the operator presses a key for forcibly changing the page of interest to a new page even if the line of interest is in the middle of the set page.

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

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

Next, an outline of the operation of the centering process in the embodiment will be described with reference to FIG.

The user (the person who uses the apparatus) moves the cursor to the line for which centering is to be designated (states 4-1 and 4-2).
Thereafter, when the centering key is pressed from the keyboard 8, the character string in the line is moved to the center and the 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). The centering in the embodiment is
If the space where characters can be inserted in the line of interest (how many more characters can be inserted in that line) is even, the character string is shifted to the true center position, and if it is odd, the character string to be centered The number of spaces before the
Shall be reduced.

Thus, the centering of the character string is performed. Thereafter, for example, in the state 4-3, when inserting a character string of "processing shift" immediately after the character string of "document edit", the following processing is performed.

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

State 4-4 in FIG. 4 shows a state in which "process" in the inserted character string "process alignment" is inserted, and state 4-5 shows a state in which the next character "no" is input. Is shown. When the character "no" is input, the space where the character can be inserted is "1", and therefore, as shown in the figure, there is one space only on the right side of the character string. After that, the character string “justification” is input. At this point, the number of inserted characters becomes equal to or larger than the space where characters can be inserted, and line overflow occurs. As described above, if the space where the character can be inserted reaches “0” (or less), the centering process is 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 the centering of the alignment information 31b in the line information for the line of interest is cleared. A display example at this time is state 4-6. In the case where the alignment information 31b is simply cleared, a normal left alignment state can be achieved by pressing a predetermined key provided on the keyboard 8.

Next, an outline of the operation of the right alignment process in the embodiment will be described with reference to FIG.

First, the user moves the cursor to the line to be right-justified (states 5-1 and 5-2). Next, when the right alignment key is pressed from the keyboard 8, the character string in the line is shifted to the right end as shown in a state 5-3, and a mark indicating the right alignment is displayed. At this time, information indicating the right alignment is stored in the alignment information 31b for the line of interest.

Thereafter, when the character string "processing alignment" is inserted immediately after "document editing" in the right-aligned character string, the following is performed.

First, if the number of inserted characters is smaller than the space where characters can be inserted in the line of interest, right alignment processing of the character string of interest including the inserted characters is sequentially performed.

A state 5-4 in FIG. 5 shows a state in which "process" in the inserted character string "process alignment" is inserted, and a state 5-5 shows a state in which the next character "no" is input. Is shown. After that, the character string “justification” is input. At this point, the number of inserted characters becomes equal to or larger than the space where characters can be inserted, and line overflow occurs. In this way, even when inserting a character string, the space where characters can be inserted is "0" (or less)
, The right justification process is meaningless. Therefore, in this embodiment, in such a case, the display of the right alignment mark is stopped, and at the same time, the alignment information in the line information for the line of interest is displayed.
Clear the data to the right of 31b. A display example at this time is state 5-6.

If an attempt is made to insert a character string after the centering processing and right alignment processing described above, and the insertion position is outside the centering or right alignment character string, the alignment information for the line of interest is cleared and displayed. The centering mark and the right alignment mark that have been erased are deleted.

FIG. 6A shows an example in which the character string "1/3" is inserted in the same line deviating from the centering character string "document edit", and FIG. 6B shows a right-aligned character string "1/3". An example in which the character string “document edit” is inserted in the same line out of the line. In each case, it is understood that the mark displayed before the insertion is deleted, and the alignment information 31b of the line information is cleared.

The operation processing procedure of the MPU 4 for realizing the above operation will be described with reference to the flowchart of FIG.

First, in step S7-1, when a character string is input from the keyboard 8, the alignment information 31b in the line information at which the cursor was located at that time is examined to determine whether the line of interest is the centered line. Is determined (step S7-2).
If it is determined that the line is not the centering line, step S7
Proceeding to -9, it is determined whether the line is a right-aligned line. If it is determined that the line is not a right-aligned line, step S7
Proceed to -13 to execute a normal character insertion process.

If it is determined in step S7-2 that the line of interest is the centering line, the process proceeds to step S7-3.
The processing described in states 4-3 to 4-6 in FIG. 4 is realized.

First, in step S7-3, it is determined whether or not there is a character insertable space in the line of interest. If it is determined that there is no such space, proceed to step S7-12, and
The centering information in 31b is cleared (the displayed mark is also deleted), and the flow advances to step S7-13. If it is determined that there is a character insertable space, the process proceeds to the next step S7-4 to determine whether the number of spaces is odd or even. Then, in each case, it is determined whether the number of input characters is even or odd (steps S7-5, S7-).
6). When the character insertable space is even and the number of input characters is odd, or when the character insertable space is odd and the number of input characters is even, in other words, when the number of input characters is inserted into the target character string If it is determined that the space where characters can be inserted becomes an odd number, step S7−
Go to 7. Here, the number of left spaces of the entire character string (= old character string + input character string) of the line of interest including the input character string is displayed in a format one less than the number of spaces on the right side of the character string. This is a process when the character string of the line of interest cannot be centered at the true center. If it is determined that the space where characters can be inserted in the entire character string including the input character string is an even number, the process proceeds to step S7-8, and the character located at the center of the character string is replaced with the character in the line. Display at the center.

If it is determined that the line of interest is a right-aligned line, the process proceeds from step S7-9 to step S7-10 to implement the processing described in states 5-3 to 5-6 in FIG.

First, in step S7-10, it is determined whether a character insertable space is generated when the input character string is inserted into the line of interest. If it is determined that there is no such space, the process proceeds to step S7-12. If it is determined that there is a space, the process proceeds to step S7-11, in which the character string before the cursor at that time is moved to the left by the number of input characters, and the input character string is set in the empty area. . still,
Although not particularly described in the above-described processing, when a step S for determining whether or not the insertion position (cursor position) of the input character is out of the character string of the line of interest is provided, the determination processing is performed. It may be located between steps S7-2 and S7-3 and between steps S7-9 and S7-10. When it is determined that the cursor is located at the deviated position, the process proceeds to step S7-12, and when it is determined that the cursor is located in the character string of the line of interest, the process proceeds to step S7-3. Alternatively, the process may proceed to 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 or the like. But,
In a document processing apparatus of the type of centering or right-aligning by inputting one character at a time, the processing becomes simpler.

For example, if the determination in step S7-4 is YES, that is, if it is determined that the space where characters can be inserted in the line of interest before insertion is an odd number, the character string after the cursor is moved right by one character. , Inserts the input one character into the vacant portion. In the case of NO, the character string before the cursor may be moved one character to the left, and the input one character may be inserted into the vacant portion.

As described above, according to the present embodiment, even if an editing process is performed on a character string in a line on which centering or right alignment processing has been performed, the edited character string is displayed according to the layout information set in that line. Therefore, an efficient editing environment can be provided.

It is convenient to display the layout state (whether right-aligned or centered) of each line for each line, so that it can be used as a reference when editing. At this time,
If no mark is displayed, it can be determined that the line is a normal mode line.

Although the editing process in the embodiment has been described mainly with reference to insertion of a character string, it is needless to say that deletion may be performed.

[Effects of the Invention] As described above, according to the present invention, when the character insertion space becomes 0 and the layout set for each line becomes meaningless, the set layout information is released. Therefore, there is no need to continue unnecessary layout processing, and processing efficiency is improved.
