Abstract

PURPOSE:To simply and accurately correct a character string by successively retrieving coincidence between the final character of a corrected character string and respective characters in a character string to be corrected from its leading character and substituting the corrected character string for a character string from the leading character of the character string to be corrected up to its coincidence retrieved character. CONSTITUTION:When an execution key 12a is depressed in the inputted and displayed state of a corrected character string 'HEISHA NI OITE', (Japanese character string means 'in our company') corresponding to a character string 'TOSHA WA' (means 'our company is') to be corrected, the leading character block 'TO' of the reversely displayed character string to be corrected is read out from a document memory 17a based upon the pointed position of a cursor pointer 17b and compared with the final character ',' of the corrected character string stored in a corrected character string buffer 17d, their coincidence/discrepancy is retrieved and the discrepancy is decided. When the coincidence of a character ',' following the character string 'TOSHA WA' to be corrected with the final character ',' of the corrected character string is retrieved, the corrected character string previously stored in the buffer 17d is substituted for the character string to be corrected stored in the document memory 17a.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to document data processing devices such as word processors and personal computers, and in particular, to character string replacement control when correcting arbitrary character strings in document data. Regarding.

[Summary of the Invention] When correcting an arbitrary character string in document data, the document data processing device of the present invention specifies the first character in the character string to be corrected, and specifies the end character of the newly input corrected character string. By sequentially searching for a match between a character and each character in the character string to be corrected, starting from the first character, and replacing the first character of the character string to be corrected up to the matching search character with the corrected character string, This makes it possible to easily and accurately correct document data character strings.

[Prior Art] Generally, in a document data processing device such as a word processor, it is possible to select between an insert mode and an overwrite mode when inputting character data.

In the former case, when a character is input in the insert mode, the character block that existed after the cursor position before the input moves in the direction of the lower digits, and a new input character is written at the cursor position. Furthermore, when characters are input in the latter overwrite mode, even if character data already exists at the cursor position, that character will be replaced with a new input character.

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

Figures 4 (A) to (C) respectively show the character string correction procedure in the above-mentioned overwrite mode. For example, if you want to correct "our company" in document data to "at our company," first, As shown in (A), place the cursor on the first character "to" of the character string to be corrected, "Our company is", and insert three space data to include "Our company" as shown in (B) of the same figure. Match the number of characters in the corrected character string to the number of characters in the corrected character string "At our company". After that, as shown in Figure (C), by inputting the corrected character string "At our company", the corrected character string "At our company" or overwrites the document position of the corrected character string "At our company" including space data. This means that corrections have been made.

Figure 5 shows the character string correction procedure in the above insert mode. First, move the cursor key to the character string to be corrected,
By operating the deletion key three times in line with the first character "to", the corrected character string "Our company wa" is deleted in advance as shown in the figure. Thereafter, by inputting the corrected character string "At our company", the corrected character string "At our company" is inserted into the part where the corrected character string "At our company" has been deleted, and the correction has been made.

[Problems to be Solved by the Invention] However, when correcting a character string using the conventional document data processing device described above, in either the overwrite mode or the insert mode, the insertion or deletion process is performed while taking into account the number of characters in the corrected character string. This requires an extremely large number of key operations, which is complicated and troublesome, and there is a risk that even necessary characters may be deleted due to an erroneous operation.

The reason for this is that when a corrected string is input, the corrected string is simply overwritten in overwrite mode, and the corrected string is simply inserted in insert mode, and the corrected string is not handled separately. It is thought that this must be done manually.

Therefore, if the corrected character string and the corrected character string are automatically replaced when the corrected character string is input, accurate character string correction can be easily performed without complicated key operations. It is clear that it will be possible to do this.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document data processing device that can easily and accurately correct a character string without having to consider the number of characters in the character string to be corrected or the number of characters in the corrected character string.

[Means to solve the problem] The means of the present invention are as follows.

(1) Document storage means for storing document data.

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

(2) Instructing means for instructing arbitrary character data in the document tab 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, they are kana character keys, alphanumeric keys, symbol keys, etc. provided on an input unit such as a keyboard. Here, character data includes kana, kanji, alphanumeric characters, symbols, and spaces.
This is data including one ruled line figure.

(4) Character search means for sequentially searching character data in the document data designated by the instruction means toward the end of the document for character data that matches the character data at the end of "Character 1" input by the character input means .

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

(5) The character data stored in the document storage means (from the character data instructed by the instruction means to the character data searched for a match by the character search means) is converted into a character string input by the character input means. replacement means.

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

[Action Co. The operation of the means of the invention is as follows.

When the first character of a character string to be corrected in document data stored in advance in the document storage means is designated by the instruction means, and a corrected character string is inputted by the character input means, the character data matches the character data at the end of the corrected character string. The character data is sequentially searched by the character search means starting from the first character data of the character string to be corrected specified by the instruction means. Thereafter, the character string from the first character of the character string to be corrected in the document data designated by the instruction means to the character data searched for by the character search means is replaced with the character string input by the character input means.

Therefore, the character string to be corrected in the document data created in advance will be automatically replaced when the corrected character string is input, so the necessary character string will not be deleted, and it will be accurate and easy to operate. You will be able to perform string corrections.

[Example] 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 device. In the figure, 11 is a central processing unit t (CPU), and this central processing unit 11 includes an input section 12, a ROM 13, a dictionary memory 14, and a display section. 15, printing section 16, and RAM
A storage section 17 using a .

The input unit 12 includes various types of keys that are operated when creating a document, including kana character keys, alphanumeric keys, symbol keys, space keys, kana/kanji conversion keys, cursor keys for specifying input positions, and execution keys. It is equipped with a function key and a correction key 12a that is operated when correcting a character string in document data. The operation of each part of the circuit is controlled based on a control program stored in advance.

The dictionary memory 14 stores kana/kanji conversion keys by the central processing unit 11 when the kana/kanji conversion key in the input unit 12 is operated.
A large number of kanji and phrase data corresponding to the kanji conversion process is stored in advance, and the character data read from the dictionary memory 14 and subjected to kana/kanji conversion is written into the document memory 17g in the storage section 17. The document memory 17a stores character data after kana/kanji conversion that is sequentially input through the central processing unit 11 as document data.
The writing start position of the input character data in this document memory 17a is indicated by the cursor pointer 17b,
The pointer value indicated by the cursor pointer 17b is controlled to increase or decrease through the central processing unit 11 in accordance with the operation of the cursor keys in the input section 12.

In addition, when creating the document data, character data such as kana characters, alphanumeric characters, symbols, etc. that are entered manually in the input section 12 before operating the kana/kanji conversion key are stored in the character buffer 17c in the storage section 17. Each character data stored in this character buffer 17c is stored in the central processing unit 11 by operating the kana/kanji conversion key.
The document is read out, converted into kana/kanji according to the dictionary memory 14, and then stored in the document memory 17a.

Furthermore, the storage unit 17 includes a corrected character string buffer 17d. In this corrected character string buffer 17d, character data inputted when operating the correction key 12a in the input section 12 and converted into kana/kanji is sequentially stored as a corrected character string, and this corrected character string buffer 17d When a corrected character string is stored in , and the execution key is operated, the last character of this corrected character string is sequentially checked by the central processing unit 11, starting with the character data in the document memory 17a indicated by the cursor pointer 17b. Search is determined through. Here, if a match is found between the last character of the corrected character string and the character data in the document data after the indicated character indicated by the cursor pointer 17b, a match is found from the character data indicated by the cursor. The document data name mountain character string up to the character data is replaced with the corrected character string under the control of the central processing unit 11.

On the other hand, the display section 15 sequentially displays character data manually entered by the input section 12, document data after kana/kanji conversion, etc. through the central processing unit 11. In this case, for example, the key manually entered character data is Display is based on the character data stored in the buffer 17c, and document data is displayed based on the document data stored in the document memory 17a. Further, the printing unit 16 performs a printing operation through the central processing unit 11 in response to the operation of a printing function key in the input unit 12. In this case, the data to be printed is read from the document memory 17a and sent to the printing unit 16. be transferred.

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

In FIG. 2, (A) to (D) respectively show the character string correction procedure performed by this document data processing device.
” is the character string to be corrected, and this is “at our company”.
To correct this, first, as shown in FIG. 3A, the cursor key on the input unit 12 is operated to point the cursor to the first character ``tou'' of the character string to be corrected ``our company wa''.

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

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

FIG. 3 is a flowchart showing the character string correction process performed by this document data processing device.
When the execution key 12a in the human power section 12 is operated with input and displayed, the first character "to" of the character string to be corrected that is highlighted in the document data is moved to the character data indicated position of the cursor pointer 17b. Based on document memory 1
7a, the central processing unit 11 compares it with the last character "," of the corrected character string stored in the corrected character string buffer 17d, and searches for a match/mismatch (steps Sl, S2). In this step S2, “
If it is determined that there is a mismatch between the last character "," of the corrected character string and the first character "F" of the corrected character string, the mismatched character (in this case "to") will be assigned the period code ",".
. ” or space code “ ” or line feed code r
It is determined whether or not it matches any CRJ (step S3). In this step S3, rNOj, that is, the character to be corrected that was determined to be a mismatch in step S2 is determined to not match any of the following characters: "Shi" is read from the document memory 17a (step S4). Then, the process returns to step S2 and the last character of the corrected character string ",
” is executed.

In this way, by repeating the determination process in steps 82 to S4, the match search process from the last character of the corrected character string "," and the first character of the corrected character string "to" is sequentially repeated, and in step S2, "match", In other words, the string to be corrected ``
When it is found that the first character "," following "Our Company is" matches the last character "," of the corrected character string, the step S2 The character string ``Our Company,'' up to the characters ``,'' determined to be a match in , is replaced with the corrected character string ``Our Company,'' stored in the corrected character string buffer 17d in advance (Step S5). Then, as shown in FIG. 2(D), the scroll display of the input display frame is canceled and the corrected display of "Our company" or "At our company" in the document data begins (Step S6). .

On the other hand, in the above step S2, in a state where a match search is not performed between the last character of the corrected character string and the first character of the corrected character string, in step S3, rYESJ, that is, the characters from the first character of the corrected character string and the period code " ” or space code “ ” or line feed code rcJ, the document memory 17
A corrected character string previously stored in the corrected character string buffer 17d is inserted before the first character of the corrected character string in a, and is displayed on the display unit 15 (steps S7→S6).

Therefore, according to the document data processing device having the above configuration,
When correcting any character string in document data, specify the first character in the string you want to correct, and match the last character of the newly input corrected string with each character in the string you want to correct. is searched sequentially from the first character of the character string to be corrected, and the characters from the first character of the character string to be corrected to the matching search character are replaced with the corrected character string, so the operator can actually specify the first character of the character string to be corrected and Document data character strings can be easily corrected simply by inputting the corrected character string. In this case, since the character string to be corrected is itself replaced with the corrected character string, necessary characters will not be accidentally erased due to overwriting or deletion after insertion.

In addition, in the character string correction processing in the above embodiment, when searching for a match from the first character of the corrected character string to the last character of the corrected character string, the character to be corrected and the period code "." or the space code "" or line break If a match is made with any character in code r CRJ, it is assumed that the correction range of the character string to be corrected has not been determined, and the corrected character string is placed before the character string to be corrected in the document data. However, for example, ■ In the same way as in the above example, the matching character "." or "" is inserted from the first character of the character string to be corrected.
or r Replace up to CRJ 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 ■ Overwrite/insert specified input mode The corrected character string may be overwritten or inserted depending on the situation.

[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 character string to be corrected or the number of characters in the corrected character string.
