Abstract

PURPOSE:To record all correcting contents when a document is corrected by providing a character deleting table to record the state of deletion and insertion of a character, a character inserting table and a table renewing part. CONSTITUTION:When an operator inputs the instruction such as the deletion, insertion, etc., of a character through a document renewing information input part 101, the contents of a character deleting table 15 or a character inserting table 107 are changed by a table renewing part 103. A document renewing part 109 renews a document 111 based upon the information from an input part 101, and the renewed document is filed through a document file reading writing part 113 to a document file 115. Thus, by collating the table 105 with the document before correction and collating the table 107 with the document after correction, it is clear which part and how the document is corrected. Even when the document is corrected >= two times, it can be recorded as to which part and how the document was corrected between the documents of two optional generations.

Description

TECHNICAL FIELD The present invention relates to a document creation device, and more particularly to a document creation device that records all modifications when a document is modified.

PRIOR ART In many conventional document creation devices, when a created document is modified (deletion, addition, correction, etc.), the modified location is not identified and displayed. It was inefficient as it required comparisons and re-reading the entire text.

In order to compensate for the above-mentioned drawbacks, Japanese Patent Application Laid-Open No. 59-793
There is a revised document confirmation method disclosed in Publication No. 41. In this method, each character in the document is stored with a 1-bit area indicating whether or not it has been modified, and when corrections such as additions or deletions are made to the document, the 1-bit area of the modified character is stored. is “O”
The purpose is to identify it by storing it as N'''.

However, this method has the following problems: (1) The character deleted from the document and its original position are not clearly indicated. (2) The state of the above 1-bit area of the character replaced by the modification before the modification is unknown. There are other problems.

Purpose The present invention was made in view of the above-mentioned circumstances, and its purpose is to solve the above-mentioned problems in conventional document creation devices, and to eliminate all the problems when a document is modified. An object of the present invention is to provide a document creation device in which modification contents are recorded.

Configuration In order to achieve the above object, the present invention provides a character string input means having character deletion and insertion functions, a means for storing a character string inputted by the input means, and a character string stored in the storage means. A document creation device having means for displaying a character string, comprising a character deletion table and a character insertion table for recording character deletion and insertion status, and a table update unit for updating the contents of the two tables when editing two documents. It is characterized by the fact that it has been provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below, followed by a more detailed explanation of the structure of the present invention based on examples.

All statement modification operations can be considered as a combination of deletion and insertion. For example, to correct "I'm going to ” can be considered to have been inserted. In another example, the modification ``rAkB or C'' → ``B or Δkc'' would be corrected even if FA and'' were moved before ``C''.
It can be considered that "A and" in front of BJ was deleted and "A and" was inserted into the cod of "C".

Therefore, there is a "character deletion table" that shows the positions of characters deleted from a document, and an r that shows the positions of characters inserted into a document.
The two tables, ``Character Insertion Table'', allow the revision history of the document to be recorded. This is the principle of the present invention, an outline of which is shown in FIG.

In Figure 3, ■ is the document before correction, 2 is the document after correction, and 3 is the document before correction.
is a character deletion table before document modification, 4 is a character deletion table after document modification, 5 is a character insertion table before document modification,
6 shows the character insertion table after document correction.

In order to simplify the explanation, here, the document before correction is assumed to be a one-sentence document consisting of four characters rABCD, and the letter is deleted from this document, and two r and '' are inserted. A revised document shall be created.

In the revised character deletion table 4, each bit in the table corresponds to the four characters in the sentence @I, and a character whose bit value is ``1'''' indicates that it was not deleted. , a character whose bit value is ``0'' is configured to indicate that it has been deleted.

In the modified character insertion table 6, each bit in the table corresponds to the five characters in the document 2, and the characters whose bit values are II, I, and 11 are characters that existed before the modification. , and a character whose bit value is 11011 is configured to indicate that it is a newly inserted character.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, 101 is a document update information input section through which the operator instructs deletion or insertion of characters, etc., and 103 is a table update section that executes table changes described later based on instructions input to the document update information input section 101. , 105 is the character deletion table illustrated earlier in FIG. 3 (3, 4), and 107 is the third character deletion table.
The character insertion table illustrated in Figures (5, 6) is shown.

Further, 109 is a document update unit that updates the document 111 based on the information from the document update information input unit 101;
Reference numeral 3 denotes a document file reading/writing unit that files a document in the external storage device 115 and reads it from there into the memory.

FIG. 4 shows an overview of the flow of creation and update processing of the character deletion table and character insertion table by the table updating section 103.

In step 12, a character deletion table is created that has a number of bits equal to the number of characters (including line feed and page break codes) of the document read in step 10, and a number of bits that is set such that the number of characters has an appropriate margin to accommodate insertion characters. Create a character insertion table with numbers. At this time, the values of all bits in these tables are set to tt 1 tr.

Next, in step 14, the character deletion table and character insertion table are updated in accordance with the document update operation by the operator.

・Figures 5 (,) to (d) show step 14 in Figure 4 in more detail; (a) is for inserting/copying characters, and (b) is for overstriking characters. This includes typing characters into blank spaces. In addition, (e) is for character deletion,
(d) shows the case of character movement.

According to this embodiment, it is possible to clearly record which part of the document has been modified and how.

FIG. 2 is a block diagram showing another embodiment of the present invention.

In the figure, symbols 101 to 111 indicate the same components as previously shown in FIG. The table-equipped document file reading/writing section 121 reads out the following information for the character deletion table 105 and character insertion table 107 when the document deletion processing section 119 deletes a document from the external storage device (table-equipped document file) 123. It shows a document deletion table update unit that performs processing to be described later.

FIG. 6 shows an example of how the character deletion table 105 and character insertion table 107 are stored together with a document in an external storage device (document file with table) 123.

In FIG. 6, the contents of the character insertion table 53 of the newly created document 51 are such that the bit value is set to "0" for all characters in the document, and the modified document 57
The contents of the character deletion table 61 are such that the bit value is set to 1'' for all characters in the document. Each document has a character insertion table (53, 59) and a character deletion table (55). , 61) and stored in the external storage bag ff123.

By doing this, even if one sentence is changed many times, the positions of characters deleted and characters added by each change can be known. 3I made by change! ! : Even when deleting some of the files of more than one generation, by changing the contents of the character insertion table and character deletion table of the files before and after the file to be deleted, the position of inserted or deleted characters may become unknown. can be prevented.

The above situation is shown in FIG. Consider a case where document 71 is changed as shown in 74, further changed as shown in 577, and then document 74 is deleted. In this case, the character deletion table 73 of the document 71 and the character insertion table 78 of the document 77
The contents of are changed as shown.

The procedure for changing the contents of each of the above-mentioned tables is as shown in FIG. In FIG. 8, (a) is the procedure for updating the character deletion table of the document file one generation before the document file to be deleted, and (b) is the procedure for updating the character insertion table of the document file one generation after the document file to be deleted. , respectively.

According to this embodiment, even if a document is modified twice or more, it is possible to see which part of the document has been modified and how between two arbitrary generations of documents.

Effects As described above, according to the present invention, by comparing the character deletion table with the document before correction and the character insertion table with the document after correction, it is possible to determine which part of the document has been corrected and how. This not only makes it clearer, but also has the remarkable effect that even if a document is modified more than once, it is possible to record which part of the document was modified and how it was modified between any two generations of documents.
