Abstract

PROBLEM TO BE SOLVED: To perform an operation matched with the sense of a user even when the post feed processing of a character string is performed by judging whether or not the text character string continues over rows from information relating to the blank of the head parts of the respective rows of the text character strings over the plural rows. SOLUTION: A character string continuity judgement means 5 judges the continuity of the character string of the two continuous rows (a preceding row and a succeeding row.) When the flocks of the preceding row and the succeeding row are the same, in the case of a normal editing mode, continuation is defined and a continuous character position in the succeeding row is defined as the head position of the succeeding row. On the other hand, in the case of a paragraph editing mode, continuation/ noncontinuation are judged by using a prescribed judgement standard and further, when the preceding row and the succeeding row are continuous, a row head position in the succeeding row is decided corresponding to a prescribed rule. That is, the character string continuity judgement part 5 handles the blank generated by a character string send-back processing the same as a general character and the operation matched with the sense of the user is performed even when the post feed processing of the character string (a blank insertion processing) is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device. In particular, it relates to a Japanese word processor (hereinafter abbreviated as word processor).

[0002]

2. Description of the Related Art A word processor usually has an editing function for inputting, deleting, and inserting a continuous character string. However, a conventional word processor uses an indenting process or the like to maintain the continuity of the character string. I needed the block editing feature.
However, with this block editing function, the user needs to manually enter the indentation by paying attention to the blocks that handle character strings as continuous, and the operation is troublesome.

That is, the display screen of the word processor is shown in FIG.
Suppose that the sentence shown in is displayed. The black square K
Is a cursor display and a character input position. After that, when "Additional grandmother" was added to this sentence, it becomes as shown in Fig. 1 (b). In this way, if the setting input operation such as indentation is not performed, the line heads in the same paragraph are not aligned. Therefore, there has been proposed a word processor having a function of aligning the line head positions by automatically shifting the cursor position to the line head position at the time of line feed without requiring input operation such as indent.

The mode based on this function is tentatively referred to as "paragraph editing mode". Further, the conventional mode is referred to as a "normal edit mode". In other words, when the sentence "Fig. 2 (a)" is additionally input, "I also had a grandmother.", It becomes as shown in Fig. 2 (b). Incidentally, such a thing is introduced in JP-A-5-46605 (G06F15 / 20), JP-A-4-119964 (G06F15 / 20), JP-A-2-100759 (G06F15 / 20) and the like. Meanwhile, as shown in the above-mentioned Japanese Patent Laid-Open No. 5-46605 (G06F15 / 20), when the deletion processing is performed, the result is as shown in FIG. That is, when the deletion process supplements the missing characters from the next line, the white space at the beginning of the line is ignored.

If the same deletion process is performed in the case of FIG. 4A in this word processor, similarly, the deficient characters are sequentially replenished from the next line onward.

[0006]

DISCLOSURE OF THE INVENTION The present invention proposes a document processing apparatus which operates in accordance with the sense of the user. Further, the present invention proposes a document processing apparatus that performs an operation suitable for the user's sense even if the character string is post-fed (blank insertion processing).

[0007]

In the present invention, an input section (2) for inputting characters and instructing editing, a text character string is edited in accordance with this input, and blanks at the beginning of a text character string extending over a plurality of lines are removed. In a document processing device that includes a character string editing unit (4) that ignores and performs editing processing as a continuous text character string, from the information about at least the leading white space of each line of a text character string that spans multiple lines, It is characterized by comprising a character string continuity judgment unit (5) for judging whether or not a text character string is continuous across lines.

Further, according to the present invention, it is continuously determined whether or not a character string is continuous over a line from information such as the number and size of blanks at the beginning of each line of a text that extends over a plurality of lines. If there is a character string continuity determination unit for determining the continuous position, and a character string editing unit for performing a continuous character string editing process including at least the character string post-advance processing, the character string post-advance processing is performed. The white space generated at this time is treated in a format different from that of a normal white space, and the character string continuity determination unit treats the white space generated in the character string backward processing as the same as a general character.

[Operation] According to the present invention, it is determined whether or not a character string is continuous across lines, based on information such as the number and size of blanks at the beginning of each line of text that extends over a plurality of lines. , It is possible to perform an editing process depending on the presence or absence of continuity of the text character string. In addition, the white space generated when performing the character string post-sending process is treated in a format different from the normal space, and the character string continuity determining unit treats the white space generated in the character string post-sending process as the same as general characters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the present invention is applied to a word processor will be shown. FIG. 5 is a schematic block diagram showing the configuration of this word processor. In FIG. 5, reference numeral 1 is a control unit including a CPU. 2 is an input unit. The input unit 2 is composed of a keyboard, a mouse and the like, and performs character input and editing instructions.

Reference numeral 3 is a display unit composed of a CRT or LCD. Reference numeral 4 is a character string editing unit having an editing function of editing a character string. Reference numeral 5 denotes a character string continuity determination unit that determines the continuity of a character string across lines and, when continuous, determines the start position of the next continuous line. FIG. 6 shows an example of criteria for determining the continuity of the character string. Here, the individual writing line means "(A)""(B)" at the beginning of the line.
This is a line in which "(1)", "(2)", ".", "A.", "B.", etc. are present.

Further, FIG. 7 shows an example of criteria for determining continuous character positions when they are continuous. For the explanation of FIGS. 6 and 7, referring to the displayed sample sentences (FIGS. 9 to 16),
I will write it later. This word processor will be described.
In this word processor, the editing mode is managed by switching between the normal editing mode and the paragraph editing mode according to the instruction from the user through a menu or the like or the situation where the editing function is used.

In the character string editing unit 4, in addition to character input processing, deletion processing, insertion processing (character string post feed processing), character modification processing, search processing, replacement processing, copy processing, movement processing, Line feed processing, size change processing,
Edit processing such as range specification processing and cursor movement processing is performed. In the one-character insertion process which is one of the insertion processes of the character string editing unit 4, as shown in FIG. 13, in the normal editing mode, a normal blank ("", blank 1) is set to 1 at the cursor position.
Insert one character and set the continuous character string after the cursor to 1
Send backwards character by character. In the paragraph edit mode, a blank (“_”, blank 2) different from the normal blank is inserted at the cursor position by one character, and the continuous character string after the cursor position is sent backward by one character.

Here, except that the blank 2 is visible in the display at the time of editing and that it is treated as a normal character in the judgment by the character string continuity judgment unit 5 described below, , May have the same properties as a normal blank (blank 1). The character string continuity determination unit 5 determines the continuity of the character strings of two consecutive lines (leading line and subsequent line). If the preceding and following blocks are different, they are discontinuous. If the blocks of the preceding and succeeding lines are the same, in the normal edit mode, they are continuous, and the continuous character position in the succeeding line is the beginning position of the succeeding line. On the other hand, in the paragraph edit mode, the judgment criterion shown in FIG. 6 is used to judge continuity / discontinuity, and when the preceding and succeeding lines are continuous, the line head position in the succeeding line is determined according to the rule shown in FIG.

In the character string continuity determination unit 5, the blank 2 is treated in the same manner as a normal character. For example, in FIG. 16, the first line is treated as a normal line, and the first character position of each line is a shaded position. FIG. 8 shows a flow of the editing processing operation of this word processor. The word processor is edited according to the operation from the input unit 2.

First, in step S1, an operation from the input unit 2 is input. In step S2, the edit mode at this time is
It is determined whether the "normal edit mode" or the "paragraph edit mode". If it is the "normal edit mode", normal edit processing is performed in step S3. If it is the "paragraph edit mode", it is determined in step S4 whether this edit affects the next line.

If it does not affect the next line, edit processing is performed in step S3. If it affects the next line,
In step S5, the continuity with the next line and the line head position in the case of continuation are determined. Then, according to the determination of the continuity, the editing process is performed in step S6. The operation of this word processor editing process will be described with reference to the sample sentences of FIGS.

Here, the operation in the paragraph edit mode and the operation in the normal edit mode are shown in contrast. FIG. 9 is an example of the input process. In A1, the character string continuity determination unit 5 determines the first line (preceding) and the second line (backward).
Since the first line (preceding) is a bullet line and the second line (subsequent line) is a blank line, the two lines are continuous from FIG. 6, and the continuous character position on the second line from FIG. 7 is the first line. First character position a
The position is a2, which is slightly rearward of 1. When one character “de” is input from the state of A1, the cursor K moves to the position of a2 as shown in A4, and thereafter, characters are sequentially input from the position of a2.

FIG. 10 shows another example of the input processing. B1
In, the character string continuity determination unit 5 determines the second line (preceding) and the third line (backward). Since the second line (preceding) is the normal line, the third line (subsequent line) is the normal line, and the first character position b2 of the third line (subsequent line) is behind the first character position b1 of the second line, According to 6, two rows are judged to be discontinuous.

When two lines are discontinuous as in this example and characters are input over one line, a new blank line is inserted between the second and third lines as shown in B4. It Therefore,
The second line (leading line) and the newly inserted blank line (backward line) are determined to be continuous lines, and the continuous character position is the position b3 of B4. Thereafter, characters are sequentially input from the position of b3. FIG.
1 is an example of the deletion process.

In C1, the character string continuity determining unit 5 determines the first line (leading line) and the second line (backward line).
Since the first line is the normal line (preceding) and the second line is the normal line (following) and the first character position of the first line (preceding) and the first character position of the second line (preceding) are the same, from FIG. The two lines are continuous. If one character is repeatedly deleted from the state of C1, C
Characters are sequentially deleted like C4 and C5, and the character on the second line is moved up to the first line.

FIG. 12 shows an example of range designation processing. E1
In, the character string continuity determination unit 5 determines the first line (preceding) and the second line (backward). The first line is the normal line (preceding), the second line is the normal line (backward), and the first character position of the first line is the same as the first character position of the second line.
From FIG. 6, two lines are continuous, and the continuous character position on the second line is the position e1. After the range designation is started in the state of E1 and the cursor is moved to designate the first line, the cursor moves to the position of the continuous character position e1 on the second line as indicated by E4. Then, as in E5, the range designation processing is continued.

FIG. 13 shows the insertion process (post-character string advance process).
This is an example. In D1, the character string continuity determination unit 5 determines the first line (leading line) and the second line (backward line). The first line is the normal line (preceding), the second line is the normal line (preceding)
Since the first character position of the first line and the first character position of the second line are the same, the two lines are continuous as shown in FIG.

When one character is inserted in the state of D1, a blank 2 is inserted at the cursor position, and a continuous character string after the cursor position is sent backward one character by one character as in D4.
When one character is repeatedly inserted, the state becomes D5. However, since the character string continuity determination unit 5 treats the blank 2 as a normal character, the first and second lines are considered to be continuous. FIG.
FIG. 4 is a diagram showing the operation of the editing process for these two types of blanks.

The difference in character input processing for the blank 1 and the blank 2 is shown. FIG. 14A shows an example of the blank 1, and since the first and second lines are discontinuous, a blank line is newly added between the first and second lines as in the input process shown in FIG. Insert and continue entering characters. FIG. 14B shows an example of blank 2, and the first and second lines are continuous, and input proceeds in a form of overwriting a continuous character string including blank 2 without creating a new blank line.

FIG. 15 is a diagram showing an operation related to a blank that occurs when the character string post feed processing is performed. FIG. 16 is a diagram showing the difference in recognition of the leading character position by the character string continuity determination unit 5 for these two types of blanks. 17 and 18
[Fig. 8] is a diagram showing another example of white space that occurs when a character string post feed process is performed.

That is, FIG. 17 and FIG. 18 show different forms of one-character insertion processing (character string post-feed processing) which is one of the insertion processing of the character string editing unit 4. Here, as shown in FIG. 17, the blank 1 is written in the text for the blank generated in the line where the character string backward processing is performed, and the blank 2 is written in the text for the blank generated in the subsequent lines. Write.

As a result, since only a normal blank (blank 1) is written in the text in the backward feeding process with a small number of characters, the complexity of the display can be reduced. In the present application, as shown in FIG. 6, the continuity of the character string is determined at the line head position, so that the operation as shown in FIG. 17 does not cause any inconvenience. In other words, consideration is required when determining the continuity of a character string in consideration of the end of line.

Further, as shown in FIG. 18, blank 1 is written in the text for a blank generated when the entire character string including the head of the continuous character string is fed backward. If it does, write blank 2 into the text). This indentation allows paragraph breaks. This makes it possible to handle character strings between paragraphs discontinuously.

[0030]

According to the present invention, it is possible to perform an editing process depending on the presence / absence of continuity of a text character string. In the paragraph edit mode, information such as the number and size of white spaces at the beginning of each line of text is used to determine whether or not a character string is continuous across lines. By performing continuous position determination and performing character string editing processing that considers the continuity of character strings, an editing function that allows users to perform block editing with a natural feeling without manually entering indents Therefore, the labor of the user can be reduced.

In particular, by distinguishing a normal blank (blank 1) from a special blank (blank 2) in the post feed processing of a character string, an editing function for performing an operation that matches the user's feeling can be realized. In other words, it is possible to perform block editing (paragraph editing) with a natural feeling without inputting indents.
