Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a word processor, and more particularly to setting various character decorations for input characters.

[0002]

2. Description of the Related Art A word processor (hereinafter, simply referred to as a word processor) is an OA (Office Automat
CRT for documents such as English and Japanese with one of the
(Catho-de Ray Tube) and LCD (Liquid Crystal Dis
(play: liquid crystal display device) is displayed on a display device to create, edit, and print a document. The created document is saved as a file in an external storage device such as a magnetic disk, and this file is saved. You can edit the document again by calling it as needed. As described above, since the stored document can be reused in the word processor and the document can be easily created and modified, it is widely used not only for the document creation in the office but also for the simple document creation at home. .

As a method of creating a document mixed with kana and kanji that is similar to a word processor, there is a method of incorporating a Japanese FEP (Front End Processor) into software called an editor. The most different point from the word processor, that is, a unique feature of the word processor is a character modification function for input characters.

The character modification function means that for a predetermined character string,
Various modifications are performed, and typical character modification functions include, for example, character enlargement (character size), hatching, enclosing, character emphasis, character color, subscript, and underline. By the way, "enlarged characters" means that double-width characters, double-height characters, 4-fold characters, or m / n double-width characters are set for double-byte characters of the basic size to set the character size. , That covers the input characters with a pre-prepared halftone pattern, "encloses" encloses the input characters with a line with a predetermined width or decoration line, and "enhances" increases the character width of the input characters , Those that add shadows, and "character color"
"Subscript" is used to set the color of input characters. "Double-byte characters" are used to perform quarter-angle processing and set superscript or subscript characters. "Underline" means a predetermined width. Line of
Alternatively, a decorative line is used to underline the input characters.

By the way, document data processed in a word processor is usually text data consisting of character codes of respective characters forming a character string, and an attribute for each character of the text data, that is, a character attribute consisting of character modification information. It contains two types of data, data and data.

For this reason, in character modification by a word processor, first, character attribute data is set, and a character string is input as text data having the character attribute data (hereinafter referred to as "preliminary modification setting"), and first modification information. A character string is input as plain text data without a character, and a predetermined character of the determined character string is subsequently subjected to a predetermined character modification (hereinafter, referred to as post-modification setting).

The procedure for applying character modification to an input character string in a conventional word processor will be described below.

In the word processor with the first modification setting, first, the operator sets predetermined character modification information, and the character attribute data of the character string to be newly input is determined based on the set character modification information.

Then, the character string input from the input means is processed in the word processor as a character code with character attribute data, and the input character string with a predetermined character modification is displayed on the display means.

On the other hand, in the word processor with the post-modification setting, first,
A character string is input from the input means in an unqualified state and is once determined as document data.

Then, the character attribute data is determined by applying a desired character modification to the predetermined character string of the confirmed document data, and the input character string with the predetermined character modification is displayed on the display means. Is displayed in.

[0012]

However, in the word processor with the first modification setting, the character modification information for the newly input character string is set in advance, and new input is made from the input means based on this character modification information. Since it was configured to add the character attribute data to the character string to be written, it is necessary to reset each time new character modification is performed, and the modification information on the existing document side and the modification information on the newly input character side are If there is a difference, there is a problem that another character modification is applied only to the part where a new character is input.

Further, in a word processor having a post-modification setting,
Since the newly input character string has no character modification, and the character string is modified afterwards for a necessary character string, the following problems occur.

That is, in a conventional word processor, when a new character string is input, it is roughly classified into an "insertion mode" for inserting a new character string into the character string of the existing document data, and an existing document data There are two operation modes called “overwrite mode” in which a new character string is overwritten on a character string. For example, as shown in FIG. 8A, “shading” is applied as a character modification. "1, 2,
When there are existing character strings up to 3, ..., 9,0 "and the cursor is located at" 6 ", the new character string" A, B, C, D "without character decoration is set in" insert mode ". 8B, the character modification is canceled only in the inserted new input character string portion, as shown in FIG. 8B.

On the other hand, the new character string "A,
When inputting "B, C, D" in the "overwrite mode", when the newly input character string is only the above-mentioned text data, the character modification of the input position is used, but the newly input character string is 8C includes the text data and the character attribute data, the character modification is canceled only for the overwritten new input character string portion, as shown in FIG. 8C.
As in the case of the "insert mode" described above, the character decoration of the new input portion is canceled.

There is also a method in which the input character has the same modification information as the modification information of the existing document data by previously checking the modification information of the existing document data at the time of inputting a new character. In this case, a new problem arises that the character is modified even when it is not necessary to modify it.

That is, in the conventional character modification, character modification may not be performed on a target character string, and character modification may be performed on an unintended character string.
In such a case, it becomes necessary to set the character decoration again and the procedure becomes very troublesome.

An object of the present invention is to perform desired character decoration on a predetermined character string by a simple operation.

[0019]

The means of the present invention are as follows.

According to the present invention, first information storage means for storing character modification information for a character string already input, second information storage means for storing character modification information for a newly input character string, and the first information storage means An information storage unit and an information setting unit for setting character decoration information of a character string to be input based on each character decoration information stored in the second information storage unit, and the character set in the information setting unit. It is characterized in that the characters inputted by the input means are modified based on the modification information.

[0021]

The operation of the means of the present invention is as follows.

According to the present invention, since the modification information of the input character string is set by the information setting means based on the respective character modification information stored in the first information storage means and the second information storage means, new input In the character string to be generated, the desired character decoration is performed on the predetermined character string in consideration of the character modification information for the character string already input and the character modification information to be newly input.

That is, desired character decoration is performed on a predetermined character string by a simple operation.

EXAMPLES Examples will be described below with reference to FIGS.

1 to 5 are diagrams showing an embodiment of the word processor according to the present invention.

First, the structure will be described. FIG. 1 is a block diagram showing a schematic configuration of a word processor of this embodiment. In FIG. 1, a word processor 1 includes an input device (input means) 2, a document editing device 3, a display device (display means) 4, a document buffer (first information storage means) 5, an input buffer 6, and an input character modification information storage unit. (Second information storage means) 7 and a modification information comparison operation unit 8.

The input device 2 is used for inputting character data, setting decoration information of an input character or setting a calculation mode of decoration information, and specifying various functions for a document.

The document editing device 3 actually creates and edits a document based on the input from the input device 2.

The display device 4 is composed of, for example, a liquid crystal display device, and displays a character string input from the input device 2, document data edited by the document editing device 3, and the like.

The document buffer 5 stores the document data being edited by the document editing apparatus 3, and the document data contains modification information for each character forming the document.

The input buffer 6 temporarily stores the character data input from the input device 2, and the character data stored in the input buffer 6 is added with the modification information determined by the modification information comparison operation unit 7. , Is stored in the document buffer 5 via the document editing device 3.

The input character decoration information storage unit 7 includes an input device 2
It stores the modification information of the characters to be input.

The decoration information comparison calculation unit 8 performs a comparison calculation between the character decoration information stored in the input character decoration information storage unit 7 and the character input position modification information extracted from the document buffer 5 and newly input. The modification information for the character data to be processed is determined.

Next, the operation of this embodiment will be described.

First, the character decoration setting for an input character in the word processor 1 shown in FIG. 1 will be described with reference to the flowchart of FIG.

First, the presence / absence of a key input from the input device 2 is detected (step S1). If there is an input, the input key is a key corresponding to character data, or a key for designating another function. It is checked which of the keys is the key (step S2).

Here, when the input key is not the key corresponding to the character data but the key for designating another function, the input function key instructs the setting of the modification information of the input character. Whether or not it is a key (step S3) is checked, and as a result of the check, if the input function key is a key for instructing the setting of the modification information of the input character, the input modification setting process is performed.

In the input modification setting process, for example, an "input modification information setting" menu is displayed as shown in FIG.
Set for each item of "Shading", "Underline", and "Box". In the example of FIG. 3, both “shaded” and “enclosed” are “none”, and a solid line is set as “underline”.

When the input modification setting process is completed,
Returning to the process of step S1, the key input acceptance state is set.

As a result of checking the function key by the processing of step S3, when the input function key is not the key for instructing the setting of the modification information of the input character, the function key calculates the input modification and the existing modification. It is checked whether or not it is a calculation mode key for instructing mode selection (step S5), and if the result of the check is that the input function key is a calculation mode selection instruction key, calculation mode selection processing is performed (step S5). S6).

In the calculation mode selection process, for example, a "calculation mode selection" menu is displayed as shown in FIG.
"Input modification priority", "Existing modification priority", "OR", "A"
A desired operation mode is selected from the operation modes such as ND "," EXOR ", ....

Here, "shading" is set as the modification information of the character input position taken out from the document buffer 5,
As shown in FIG. 5A, “1, 2, 3, ..., 9,
For existing character strings up to 0 ", the new character string" A, B, C, D "in which" underline "is set as the character modification information stored in the input character modification information storage 7 is set to" overwrite mode ".
Each calculation mode will be described by taking as an example the case of inputting with.

The "input modification priority" mode is a mode in which the modification information of the character stored in the input character modification information storage unit 7 is preferentially used as the modification information of the newly input input character, as shown in FIG. ), When the cursor is located at “6” for an existing character string up to “1, 2, 3, ..., 9, 0” for which “shading” is set, a new character When "A, B, C, D" is input as the column, a character string in which "underline" is set as the modification information is newly input as shown in FIG.

The "existing modification priority" mode is a mode in which the modification information of the character input position extracted from the document buffer 5 is prioritized as the modification information of the newly input input character, and the "input modification priority" described above is used. Similar to the mode, when the cursor is located at “6” for the existing character strings up to “1, 2, 3, ... When "A, B, C, D" is input as, a character string in which "shading" is set as the modification information is newly input as shown in FIG.

In the "OR" mode, an OR (logical sum) operation is performed between the character decoration information stored in the input character decoration information storage unit 7 and the character input position decoration information retrieved from the document buffer 5. This is the mode to use as the modification information of the newly input input character. As with the above-mentioned “input modification priority” mode, “1,” with “shaded” is set.
When the cursor is positioned at “6” for existing character strings up to 2, 3, ..., 9,0 ”, and when“ A, B, C, D ”is input as a new character string, As shown in (d), a character string in which "shading" and "underline" are set as the modification information is newly input.

In the "AND" mode, the character decoration information stored in the input character decoration information storage 7 and the document buffer 5 are stored.
AND with the modification information of the character input position extracted from
In this mode, which is used as decoration information for a newly input character by performing (logical product) operation, as in the case of the "input modification priority" mode described above, "1, 2, When the cursor is positioned at "6" for the existing character strings up to 3, ..., 9,0 "and" A, B, C, D "is input as a new character string, FIG. ), A character string in which nothing is set as the decoration information is newly input.

In the "EXOR" mode, the EX between the character decoration information stored in the input character decoration information storage unit 7 and the character input position decoration information extracted from the document buffer 5 is EX.
This mode is used as modification information of an input character newly input by performing an OR (exclusive OR) operation. Like the above-mentioned "input modification priority" mode, "1" with "hatched" is set. , 2, 3, ..., 9, 0 ", when the cursor is positioned at" 6 "for the existing character string, if" A, B, C, D "is entered as a new character string, In this case, as in the case of the OR (logical sum) processing, a character string in which "shading" and "underline" are set as the modification information is newly input.

That is, in FIG. 5B, since the operation mode is the input modification priority mode, an underline is added, and FIG.
In (c), hatching is added because the mode is the existing modification priority mode. Further, in FIG. 5 (d), since it is the OR mode, hatching and underlining are added, and in FIG. 5 (e), since it is the AND mode, the same type of modification is applied on the input side and the existing side. Since there is no such modification, no modification is added.

When the calculation mode selection process is completed, the process returns to step S1 to enter the key input acceptance state.

As a result of checking the function keys by the processing of step S5, if the input function key is not the calculation mode selection instruction key, the function corresponding to the input function key is executed (step S7). Returning to the process of step S1, the key input acceptance state is set.

On the other hand, based on the processing in step S2, when the input key is a key corresponding to character data, the modification information comparison operation unit 8 acquires the existing modification information at the character input position and (Step S8), the existing modification information and the modification information of the input character are calculated (step S9).

Then, the newly input character data is set as the document data based on the modification information obtained in step S9 (step S10).

Thereafter, the process returns to the step S1 and the above-mentioned process is repeated.

As described above, in this embodiment, by providing a calculation mode in which a predetermined logical operation is performed between the existing decoration information and the input decoration information, various decoration information can be set at the time of character input. it can.

Even when a new character is added to a character string that has already been input, it is possible to give priority to the existing decoration information or the decoration information of a new character string according to the setting mode. You can

FIGS. 6 and 7 are views showing another embodiment of the word processor according to the present invention.

In the above-mentioned one embodiment, the modification information of the newly input character is determined based on the preset operation mode. In this embodiment, in addition to the above-mentioned one embodiment, the "switch key" is added. "Is provided, and the calculation mode is changed each time the" switch key "is pressed.

The process of changing the calculation mode will be described below with reference to the flow chart shown in FIG.

As the input condition, as in the case shown in FIG. 5, "1,2," in which "shading" is set as the modification information of the character input position extracted from the document buffer 5.
New character strings "A, B, C" in which "underline" is set as the character modification information stored in the input character modification information storage 7 for existing character strings up to 3, ..., 9, 0 " , D "are input in the" overwrite mode ".

When the operation mode is the “input modification priority” mode, “1, 2, 3, ...
When the cursor is located at "6" for the existing character string up to 9,0 ", the new character string is" A, B, C, D ".
7 is input, a character string in which “underline” is set as the modification information is newly input as shown in FIG.

When the switch key is pressed, the operation mode is switched from the "input modification priority" mode to the "existing modification priority" mode (step P1), and the modification information comparison operation unit 8 allows the existing modification information and the input character to be recognized. The calculation with the modification information is executed (step P2), and the new character string "A" is added to the existing character strings up to "1, 2, 3, ... , B, C, D ", a character string in which" shading "is set as the modification information is input and displayed as shown in FIG. 7B (step P3).

Every time the switch key is pressed, "input modification priority" → "existing modification priority" → "OR" → "AND" →
The display is changed while switching the calculation mode as in “EXOR” → “input modification priority” → ...

As a result, in this embodiment, in addition to the above-described embodiment, the character decoration information can be easily set.

As described above, according to the present invention, since the arithmetic mode is provided between the existing modification information and the input modification information, various kinds of modification information can be easily realized at the time of character setting. , When adding a character string that has already been input, prioritize existing decoration information according to the setting mode,
The decoration information of a new character string can be given priority.

In the above embodiment, the logical operation is O
Although R, AND, and EXOR are taken as an example, it goes without saying that other logical operations may be applied.

[0066]

According to the present invention, since the modification information of the input character string can be set by the information setting means based on the respective character modification information stored in the first information storage means and the second information storage means, a new The character string to be input can be subjected to desired character decoration on a predetermined character string in consideration of the character decoration information for the character string already input and the character decoration information to be newly input.

Therefore, in the present invention, it is possible to easily perform a desired character modification on a predetermined character string by a simple operation.
