Description

The present invention relates to a document data processing device such as a word processor or a personal computer, and in particular, to character string replacement control when correcting an arbitrary character string in document data. About.

[Summary of the Invention] When correcting an arbitrary character string in document data, the document data processing apparatus of the present invention specifies the first character in the character string to be corrected and ends the newly input corrected character string. By sequentially searching for a match between a character and each of the characters in the character string to be corrected from the first character, and replacing the first character of the corrected character string to the matching search character with the corrected character string, The purpose of the present invention is to make it possible to easily and accurately correct a character string.

2. Description of the Related Art Generally, in a document data processing device such as a word processor, when inputting character data, an insertion mode and an overwrite mode can be selected.

When the former character input is performed in the insertion mode, character data existing after the cursor position before the input is shifted in the lower digit direction, and a new input character is written at the cursor position. When the character is input in the latter overwrite mode, even if character data already exists at the cursor position, the character is rewritten with a new input character.

By the way, there is a case where it is desired to correct a certain character string in the document data created in advance.

FIGS. 4 (A) to 4 (C) each show a character string correction procedure in the overwrite mode. For example, when it is desired to correct "our company" in the document data as "our company", FIG. As shown in (A), the cursor is placed on the first character "this" of the corrected character string "Our company", and FIG.
As shown by, three characters of space data are inserted, and the number of characters of the corrected character string including "we are" is adjusted to the number of characters of the corrected character string "at our company". Thereafter, as shown in FIG. 10C, by inputting the corrected character string "at our company", the corrected character string "at our company" overwrites the document position of the corrected character string "our company" including space data. This means that the correction has been made.

FIG. 5 shows the character string correction procedure in the above insertion mode. First, the cursor key is set to the first character of the character string to be corrected "Our company" and the delete key is operated three times. As shown in the character string to be corrected
Is deleted in advance. After this, the correction string "at our company"
By inputting, the corrected character string "at our company" is inserted into the portion where the corrected character string "we are" is deleted, and the correction is performed.

[Problems to be Solved by the Invention] However, when performing the character string correction in the above-described conventional document data processing apparatus, in either the overwriting mode or the insertion mode, the insertion or deletion processing is performed in consideration of the number of characters of the corrected character string. Must be performed, the key operation for it becomes very large, it is complicated and troublesome,
Erroneous operation may delete necessary characters.

Such a cause is that when the correction character string is input, the correction character string is simply overwritten in the overwrite mode, and the correction character string is simply inserted in the insertion mode. It is thought that the operation must be performed.

If the corrected character string is automatically replaced with the corrected character string when the corrected character string is input, accurate character string correction can be easily performed without complicated key operations. Obviously, you will be able to

SUMMARY OF THE INVENTION An object of the present invention is to provide a document data processing apparatus capable of easily and accurately correcting a character string without having to consider the number of characters in the corrected character string and the corrected character string.

[Means for Solving the Problems] The means of the present invention are as follows.

(1) Document storage means for storing document data.

For example, it is a document memory composed of a RAM or the like. Here, the document data is data created by a set of one or more character data.

(2) Instruction means for instructing arbitrary character data in the document data stored in the document storage means.

For example, it is a cursor key provided on an input unit such as a keyboard.

(3) Character input means for inputting character data.

For example, a kana character key, an alphanumeric key, a symbol key, and the like provided in an input unit such as a keyboard. Here, the character data is data including ruled lines and figures in addition to kana, kanji, alphanumeric characters, symbols, and spaces.

(4) A character search means for sequentially searching character data in the document data designated by the instruction means from the character data in the document data designated by the instruction means in the document end direction, for character data matching the character data at the end of the character string input by the character input means.

For example, a CPU that operates according to a program stored in a ROM.

(5) Replace the character data of the document data stored in the document storage means from the character data designated by the designation means to the character data matched and searched by the character search means with the character string inputted by the character input means. Replacement means.

For example, a CPU that operates according to a program stored in a ROM.

[Operation] The operation of the means of the present invention is as follows.

Instructing the first character of the corrected character string of the document data previously stored in the document storage means by the instructing means,
When the corrected character string is input by the character input means, character data matching the character data at the end of the corrected character string is sequentially searched by the character search means from the leading character data of the corrected character string designated by the instruction means. You. Then, the character string input from the character input means is replaced from the first character of the corrected character string of the document data specified by the specifying means to the character data matched and searched by the character search means.

Therefore, the corrected character string in the document data created in advance is automatically replaced when the corrected character string is input, so that the required character string is not erased, and accurate and easy to operate. Character strings can be corrected.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a document data processing apparatus. In FIG. 1, reference numeral 11 denotes a central processing unit (CPU). The central processing unit 11 has an input unit 12, a ROM 13, a dictionary memory 14, and a display unit 15. , A printing unit 16 and a storage unit 17 using a RAM.

The input unit 12 includes various keys such as a kana character key, an alphanumeric key, a symbol key, a space key, a kana / kanji conversion key, a cursor key for designating an input position, an execution key, etc. A function key, and a correction key 12a operated when correcting a character string in the document data.The central processing unit 11 stores the function key in the ROM 13 according to a key input operation signal supplied from the input unit 12. The operation of each part of the circuit is controlled based on a control program stored in advance.

The dictionary memory 14 previously stores a large number of kanji and idiom data corresponding to the kana / kanji conversion processing by the central processing unit 11 when the kana / kanji conversion key in the input section 12 is operated. Kana read from 14 /
The character data after the kanji conversion is stored in the document memory in the storage unit 17.
Written on 17a. The document memory 17a stores, as document data, kana / kanji converted character data sequentially input through the central processing unit 11.
The writing start position of the input character data in 17a is indicated by the cursor pointer 17b, and the pointer indicated value in the cursor pointer 17b is controlled to increase or decrease through the central processing unit 11 according to the operation of the cursor key in the input unit 12.

In addition, when creating the document data, character data such as kana characters, alphanumeric characters, and symbols input by the input unit 12 before operating the kana / kanji conversion key are stored in a character buffer 17c in the storage unit 17. Are stored sequentially,
By operating the kana / kanji conversion key, this character buffer 17
Each character data stored in c is read out by the central processing unit 11, converted into kana / kanji in accordance with the dictionary memory 14, and then stored in the document memory 17a.

Further, the storage unit 17 includes a correction character string buffer 17d. The correction character string buffer 17d has the input unit 1
The character data that is input at the time of operation of the correction key 12a in 2 and is converted into kana / kanji is sequentially stored as a corrected character string. Then, with the character at the end of the corrected character string on the document memory 17a indicated by the cursor pointer 17b as the head, the match / mismatch is sequentially searched and determined through the central processing unit 11. Here, when a match between the last character of the correction character string and the character data in the document data after the designated character indicated by the cursor pointer 17b is found, a match is found from the character data designated by the cursor. The character string in the document data up to the input character data is replaced with the corrected character string under the control of the central processing unit 11.

On the other hand, the display unit 15 sequentially displays, through the central processing unit 11, character data input by key input from the input unit 12, document data after kana / kanji conversion, and the like. The document data is displayed based on the character data stored in the buffer 17c, and the document data is displayed based on the document data stored in the document memory 17a. The printing unit 16 performs a printing operation through the central processing unit 11 in accordance with an operation of a printing function key in the input unit 12. In this case, data to be printed is read out from the document memory 17a and sent to the printing unit 16. Will be transferred.

Next, the operation of the document data processing device having the above configuration will be described.

FIGS. 2A to 2D each show a character string correction procedure by the document data processing apparatus. For example, "Our company" in the document data created in advance and stored in the document memory 17a is corrected. To correct the character string as “at our company”, first, as shown in FIG.
By operating a cursor key in the input unit 12, the first character "this" of the character string to be corrected "this company" is indicated by the cursor.

Here, when the correction key 12a in the input section 12 is operated, as shown in FIG. 2 (B), the first character "this" of the corrected character string indicated by the cursor (cursor pointer 17b) is highlighted. At the same time, the next line after the line in which the corrected character string exists is scrolled by one line, and an input display frame f for inputting the corrected character string is displayed corresponding to the corrected character string. Then, as shown in FIG. 2 (C), the corrected character string “at our company” is input to the input display frame f including the first common character (in this case, “,”) following the character string to be corrected. When inputting and converting kana / kanji, this corrected character string "at our company"
Stored in d.

The input display frame f is enlarged according to the number of input characters.

FIG. 3 is a flow chart showing a character string correction process by this document data processing apparatus, in which the corrected character string "at our company" is input and displayed corresponding to the character string to be corrected "our company" as described above. When the execution key 12a of the input unit 12 is operated, first, the first character "this" of the corrected character string which is highlighted in the document data is stored in the document memory 17a based on the character data designated position of the cursor pointer 17b.
Are compared with the last character "," of the corrected character string stored in the corrected character string buffer 17d in the central processing unit 11, and a match / mismatch thereof is searched (steps S1, S2). In this step S2, if it is determined that "mismatch", that is, the last character "," of the corrected character string does not match the first character "this" of the corrected character string,
The mismatched character (in this case, “this”) is the period code “.”
Alternatively, it is determined whether or not it matches either the space code "" or the line feed code "CR" (step S3).
"NO" in step S3, that is,
The corrected character "this" determined to be mismatched in S2 is "."
If it is determined that the character string does not match any of "" and "CR", the character "sha" next to the character string to be corrected is read from the document memory 17a (step S4). Then, the process returns to the step S2 to execute a matching search process with the corrected character string end character “,”.

Thus, by repeating the determination processing in steps S2 to S4, the matching search processing from the corrected character string end character “,” and the corrected character string head character “this” is sequentially repeated, and in step S2, “match” That is, when it is found that the first character “,” following the corrected character string “Our company” matches the last character “,” of the corrected character string, the document memory 17
The character string `` Our company '' from the first character `` this '' of the corrected character string in a to the character ``, '' determined to match in the above step S2 is the corrected character string `` stored in the corrected character string buffer 17d in advance. In our company, it is replaced with "" (step S5). Then, as shown in FIG. 2 (D),
The scroll display of the input display frame is released, and “Our company” in the document data is corrected and displayed as “At our company” (step S6).

On the other hand, in step S2, in a state where the matching search from the last character of the corrected character string and the first character of the corrected character string is not performed, in step S3, "YES", that is, the character and the period When a match with any of the characters of the code ".", The space code "", or the line feed code "CR" is determined, the corrected character string buffer 17 is placed before the first character of the corrected character string in the document memory 17a.
The corrected character string stored in advance in d is inserted and displayed on the display unit 15 (step S7 → S6).

Therefore, according to the document data processing apparatus having the above configuration, when correcting an arbitrary character string in the document data, the first character in the character string to be corrected is designated, and the last character of the newly input corrected character string is corrected. And the characters in the character string to be corrected are searched sequentially from the first character.
Since the characters from the first character of the corrected character string to the matching search character are replaced with the corrected character string, the operator can simply perform the operation of specifying the first character of the corrected character string and the operation of inputting the corrected character string. Thus, the correction of the document data character string can be easily performed. In this case, the corrected character string itself is replaced with the corrected character string, so that even a necessary character is not accidentally erased by overwriting or deletion after insertion.

In the character string correction process in the above-described embodiment, at the time of a match search from the corrected character string first character to the corrected character string end character, the corrected character and the punctuation code “.” Or the space code “” or the line feed code “ If a match with any of the characters "CR" is determined, it is assumed that the correction range of the corrected character string could not be determined, and the corrected character string is placed before the corrected character string on the document data. Although the processing for insertion is performed, for example, in the same manner as in the above embodiment, the matching character "."
Or, replace up to "CR" with the corrected character string stored in the corrected character string buffer 17d, overwrite the corrected character string from the first character position of the corrected character string, or
Either overwriting or inserting a corrected character string may be performed in accordance with the overwriting / inserting designation input mode.

[Effects of the Invention] As described above, according to the present invention, it is possible to easily and accurately correct a character string without having to consider the number of characters in the corrected character string and the corrected character string.
