Abstract

PURPOSE:To make the line head of a next line uniform at the position of an optional character in the middle of the line based on this position of the character in the middle of the line. CONSTITUTION:When input character data exceeds the number of digits per one line at the time of the input of the character data from a keyboard 13, a CPU 11 retrieves successively each character data of the present line, and simultaneously, it discriminates whether the character data added with digit position control information as character qualification information is contained in the present line or not. As the result, if it is not contained in the present line, a margin position and an indent position are made the starting digit position of the next line, but if it is contained, the digit position of this character is made the starting digit position of the next line.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document input device such as a word processor and a personal computer.

[0002]

2. Description of the Related Art Conventionally, in a document creating apparatus such as a word processor, if left and right margin positions are set at the time of creating a document, one page of document data is created between the set margin positions. In this case, the left and right margin positions are set for each line at the same time when the digit is indented, and when the character is added later, the same margin position is copied to the next line, so that the same line head position is set for multiple lines. Some of them are aligned to the digit position. Furthermore, in the case where the indent function is provided, the indent position is not limited to the case where the line heads are aligned to the position, but if a position that is shifted toward the end of the line from the margin position is preset as the indent position, this indent position will be You can align the beginning of the line.

[0003]

As described above, in the prior art, the column position can be managed only at the start column position (line start position) and the end column position (line end position) of the line. Therefore, for example, in a document as shown in FIG. 6A, assuming that the first column start column position is the left margin position and the second line start column position is the indent setting position, the second line midway (Fig. Even if an additional sentence is inserted in the middle arrow position)
As shown in (B), the line head positions of the third and fourth lines are correctly indented and aligned with the indent position. By the way, in the case of a document as shown in FIG. 6C, that is, 1
When an additional sentence is inserted at the arrow position in the figure when a plurality of character strings with different line head positions are included in the line, (D) in FIG.
It is not possible to obtain a document of the form shown in FIG. 6, and the document shown in FIG. That is, in the first line, the beginning of the line is the first character position (left margin position) of the first character string "purpose of invention", and an indent can be set at the first character position of the next character string "present invention". Because I can't
The beginning of the second line is aligned with the left margin position. In such a case, it is necessary to re-edit the second and subsequent lines of the document shown in FIG. 6E after the document is added to change the layout state to the form shown in FIG. 6D. The subject of this invention is
This is so that the start of the next line can be aligned with this position with reference to an arbitrary character position in the middle of the line.

[0004]

The means of the present invention are as follows. Discriminating means 1 (see the functional block diagram of FIG. 1,
The same shall apply hereinafter) means that when the number of digits per line is exceeded when entering character data, each character data in the current line is searched sequentially and the character data to which digit position management information is added as character decoration information is displayed in the current line. Is included in. In this case, the character string of the current line is searched character by character from the end of the line toward the beginning of the line. Here, the character modification information is added to the character data to define the size of the character, the shape of the character, etc. In most cases, this modification information can be expanded. Is effectively used for digit position management. When it is determined by the determining means 1 that the character data to which the digit position management information is added is included in the current line, the first start digit position determining means 2 determines the digit position of this character data in the next line. Determined as the starting digit position. When it is determined by the discriminating means 1 that the character data to which the digit position management information is added is not included in the current line, the second start digit position determining means 3 sets a preset line head position management information ( The start column position of the next line is determined based on the margin position, indent position, etc.).

[0005]

The operation of the means of the present invention is as follows. Now, an arbitrary character in the middle of a line is designated, and digit position management information is added to the character modification information of the designated character. In this state, when the number of digits per line set in advance as the format information at the time of inputting the character data is exceeded, the discriminating means 1 determines each character data of the current line from the end of the line to the beginning of the line. While sequentially searching, it is determined whether or not the current line includes character data to which digit position management information is added as character decoration information. Now, when the character data to which the digit position management information is added is not included in the current line, the second start digit position determining means 3 operates as usual.
The start column position of the next line is set to the margin position, the indent position, etc. based on the line head position management information set in advance. On the other hand, when the character data to which the digit position management information is added is included in the current line, the first start digit position determining means 2 determines the digit position of this character data as the start digit position of the next line. Therefore, the start of the next line can be aligned with this character position based on an arbitrary character position in the middle of the line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 2 is a block diagram showing the basic configuration of the word processor. The CPU 11 controls the overall operation of this word processor in accordance with various programs stored in the ROM 12 and the like. The CPU 11 has a keyboard 13, a CRT display device 14, and a disk device 15 which are peripheral devices thereof.
6, a CRT control unit 17, and an external storage control unit 18 are connected. The ROM 12 stores a program for loading the operating system into the RAM 19 when the system is started up, an input / output control program, and the like.
Stores character font data. The keyboard 13 is a key input device equipped with character keys, cursor keys, etc., and the keyboard control unit 16 uses a CP key code corresponding to the operation key.
Give to U11. In this case, the CPU 11 uses the keyboard 1
When the document data is input from 3, this document data is
It is stored in the document storage area 19-1 of the AM 19. CRT
The display device 14 displays document data and various message data, and the CRT control unit 17 reads out image data in the video RAM (VRAM) 20 under the control of the CPU 11 and causes the CRT display device 14 to display and output the image data.

The disk device 15 stores a program file, a document file, etc., and has an external storage controller 18
Accesses the disk device 15 under the control of the CPU 11 to write / read data. The RAM 19 is a document storage area 19 for storing document data, format information and the like.
1, the document data stored in the document storage area 19-1 has a work area 19-2.
It is stored in bytes. In this case, the character decoration information added to each character data defines character position information such as character attributes such as character size and character shape. This digit position management information indicates the character start digit of the next line, and unlike the margin position and the indent position, any character position in the middle of the line is defined as the character start position of the next line.
The digit position management information is the same as normal character modification information.
It does not affect the display / printing.

Next, the operation of this embodiment will be described. FIG. 3 is a flow chart showing the operation at the time of character input. When the character key on the keyboard 13 is operated (Y in step A1).
ES), the character data corresponding to the operation key is input at the current cursor position (step A2). In this case, when the character attributes such as the character size and the character shape are designated (YES in step A3), character modification information indicating the character size and the like is added to the character data (step A4). ..
On the other hand, when the other keys except the character keys are operated, the process proceeds to step A5, and it is checked whether or not a predetermined key to which the digit position management information should be added is operated. Here, when the predetermined key is operated, the character at the current cursor position is designated, and the digit position management information is added to the modification information of this character (step A6). When it is detected in step A5 that another key (cursor key, execution key, indent key, etc.) is operated, other processing corresponding to the operation key is executed (step A7).

FIG. 4 is a flow chart showing the operation for determining to which column position the input character should be moved when it wraps around to the next line. Now, as shown in FIG. 5, after the first character string "object of the invention" on the first line is followed by another character string "present invention ...", The first character "book" of this character string When the digit position management information indicated by the US mark in the figure is added to the modification information of, the additional sentence "by improving the input device" is inserted at the arrow position in the figure.

First, when this flow chart is started, the current line is designated one digit at a time from the end of the line toward the beginning of the line, so that the current column position is set at the end of the line (step B1). Next, the digit position is moved to the left by one digit (step B2). It is checked whether the designated digit position is a preset indent position (step B3), the left margin position (step B4), or the digit delimiter position where the digit position management information is added to the character decoration information (step B3). B5). Where the current digit position is the indent position,
If it is neither the left margin position nor the digit separation position, return to step B2 and move the current digit position to the left by one digit,
Thereafter, the above-described operation (steps B2 to B5) is repeated while moving the digit position to the left by one digit until the indent position, the left margin position, and the digit division position are detected.

If the current digit position is set to the character position of "book", since the digit position management information is added to this character modification information, it may be a digit separation position in step B5. To be detected. In this case, the process proceeds to step B6, where the digit position management information is added to the character data of the same digit in the next line by the character modification information method. To do. When the current digit position is set to the preset indent position, the current digit position is set as the start digit position of the next line (step B7). Further, when the current digit position is set to the preset left margin position, the process proceeds to step B7,
The current column position is the start column position of the next line.

When a character is inserted in this way and the end-of-line character of the current line wraps around to the next line, a character search is performed from the end of the line of the current line toward the beginning of the line. When the management information (US mark) is searched, the character search is stopped at this point and the position of this US mark is used as the starting column position of the next line, but the column position management information is included in the middle of the current line. If not, the indent position or the left margin position becomes the starting column position of the next line. As shown in FIG.
Even if the additional sentence is inserted in the first line of the document, the document form as shown in FIG. 6E is not obtained, but the desired document form as shown in FIG. 6D is obtained.

[0013]

According to the present invention, the line head of the next line can be aligned with this character position based on an arbitrary character position in the middle of the line, so that automatic indentation suitable for a complicated document is also possible. Is possible.
