Abstract

PURPOSE:To clarify a character string edited with the editing processing by editing stored characters to compare them with a document before editing and distinctively outputting extracted points of difference. CONSTITUTION:In case of the editing processing where an original document generated and printed beforehand is read from a magnetic disk device 4 to a RAM 5 and a part of this document is corrected, a deletion or insertion start code and a deletion or insertion end code are inserted before and after the edited and corrected character string. These codes are discriminated at the time of reading out document information from the RAM 5 by an MPU 3 and are distributed to picture areas for black, red, and blue in an image memory 6, and the deleted or inserted character string is printed in a color different from that of the original document by a printer 8. Thus, the printed edited document is seen to clarify which part is deleted from or inserted to the original document.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device for creating and editing documents.

[Background Art] In recent years, with the development of document processing devices such as word processors, it has become possible to easily create and edit documents.

By the way, if you modify a part of a document previously created using this type of device, you can not only print the revised document but also print a correction list (or errata, etc.) that clearly shows the revised parts in the document that has already been distributed. ) was created and printed separately.

[Problems that the invention aims to solve: However, it is extremely troublesome to compare previously printed documents and revised documents and create a revision table one by one.
The trouble of creating the correction table was ignored.

The present invention has been made in view of the above prior art, and it is an object of the present invention to provide a document processing device that makes it possible to clearly output the modified portions in a document.

[Means for solving the problem] In order to solve this problem, the present invention has the configuration shown below.

That is, a storage means for storing document information, an editing means for editing the stored document information, an extraction means for extracting differences between the edited document information and the document information before editing, and an extraction means for extracting differences between the edited document information and the document information before editing. and output means for distinguishing and outputting the differences.

[Operation] In the configuration of the present invention, the document stored by the storage device is edited by the editing device, and as a result of the editing process, differences are extracted by the extraction device by comparing the document with the document before editing,
The differences extracted by the extraction means are distinguished and output.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Explanation of the outline of the structure (FIGS. 1 and 2)] FIG. 1 is a diagram showing the outline of the structure in this embodiment.

In the figure, 1 is a display device (hereinafter referred to as a CRT in a car) for displaying documents or various messages, and displays image data developed in a VRAM 2 on its display screen. 3
is a microprocessor (hereinafter referred to as M) that controls the entire device.
Internal ROM 3alI: It controls and operates according to the stored program. Incidentally, this ROM 3a also stores a program related to document editing processing and a program of the flowchart shown in FIG. 5.6.7. 4 is 6 which can store multiple document files.
It is an n-air disk device, and 5 is a RAM for storing document information read from the magnetic disk device 4 and document information to be created or edited. Note that a part of this RAM 5 is used as a work area for the MPU 3. Reference numeral 7 denotes an image reading device for reading original images, and displays or prints images inputted by the image reading device 7 mixed with the document being edited as necessary. A printer 8 is capable of printing in three colors, black, red, and blue, and prints the image data developed in the image memory 6. FIG. 2 shows the contents of this image memory 6. As shown in the figure, it is divided into three areas depending on the output color during printing. For example, when printing in black, the black image area 6
All you have to do is expand the image to 1. In this embodiment, the size of each area 61 to 63 is one page of printing paper, and after developing an image in each area, they are combined to form a single page.
Print the page in three colors. A keyboard 9 is used along with the mouse 10 for document editing and various menus.

[Explanation of processing outline (FIGS. 3 and 4)] The contents from editing processing to printing processing in this configuration will be explained below.

FIG. 3(a) shows a previously created and printed document (hereinafter referred to as an original document), which is stored in the magnetic disk device 4. Now, read this original document from the magnetic disk device 4 into the RAM 5, delete the character string "Yayuyo" in the first line, and insert the character string "Tachi" between "so" and "na" in the second line. Let's consider the editing process that inserts "Tsuteto".

In this embodiment, in order to clearly identify the location where this editing process has been performed, the deleted or inserted character strings are printed on the printer 8 in different colors with respect to the original document. For example, as shown in FIG. 3(b), when printing an edited document in black, deleted characters such as character string 31 in the edited document are printed in red, and inserted characters such as character string 32 are printed in black. The columns will be printed in blue. Therefore, by looking at this printed edited document, it becomes clear which parts have been deleted or inserted from the original document. In the first embodiment, when an original document is edited, a deletion start code, a deletion end code, etc. are inserted before and after the edited character string, as shown in FIG. Note that the deletion start code and deletion end code may be the same code as long as they can be distinguished from other character symbol codes. Furthermore, the same applies to the insertion process; when inserting an inserted character string at the position to be inserted, insertion start and end codes are added before and after the inserted character string.

Therefore, when printing a document that has been edited, the RA
When the MPU 3 reads document information from M5, it determines whether there is a character string sandwiched between deletion start/end codes or insertion start/end codes, and writes it to each area 61 to 63 in the image memory 6. It will be allocated and expanded. In this way, each time an image for one page is developed, it is printed out by the printer 8.

[Description of Editing Process (FIG. 5)] The editing process described above can be briefly summarized as a flowchart shown in FIG. 5. The following will explain according to this flowchart.

First, in step S1, an original document is read from the magnetic disk device 4 into the RAMH. Next, in step S2, information related to editing processing is input using the mouse 10 and keyboard 9. In step S3, it is determined whether the input information means deletion of a character string. If the determination is "YES", the process moves to step S4, and a deletion start code is inserted before and after the deleted character string. Insert deletion exit code.

Further, when the determination in step S3 is "No", it is determined in step S5 whether or not a character string is to be inserted. At the time of insertion, the process proceeds to step S6, where an insertion character string is inserted at the insertion point in the original document, and an insertion start code and an insertion end code are inserted before and after the insertion character string.

Further, in step S5, if it is determined that the input information in step S2 is not information related to character string insertion, the process moves to step S7, and it is determined whether the input information means the end of editing processing. You will have to judge. If this input information is determined to be information that means the end of editing, the editing process is ended, but if not, other processing is performed in step S8, such as processing of moving the cursor on the editing screen. will be done.

Through the above-described processing, control codes are inserted before and after the character string of the edited portion of the original document based on the editing processing.

[Description of Print Processing] Now, the document after the editing process will be printed, and the details of the process will be explained with reference to FIG.

In step Sll, the MPU 3 reads document information from the RAM 5 at any time. At this time, if it is determined that there is a deleted character string, that is, if it is determined that there is a character string sandwiched between the deletion start/end codes, the process moves from step S12 to step S13, and an image of the deleted character string is The pattern is developed in the red image area 62.

Further, if it is determined that there is an inserted document in the read document, that is, if it is determined that there is a character string sandwiched between insertion start/end codes, the process moves from step 514 to step S15, and the inserted document is inserted. The image pattern of the character string is developed in the blue image area 63.

Furthermore, if it is determined in step S14 that there is no inserted character string, the character string information read from the RAM 5 is developed in the black image area 61.

In this way, the image pattern is developed in one of the areas 61 to 63, but in step S7, the image pattern is
It is then determined whether all the documents stored in the file have been read. If this judgment is "YES", the image pattern developed in each area 61 to 63 is still 1
Even if it is not enough for one page, it will be printed in step 320.

If 'NO', it is determined whether one page's worth of image patterns has been developed in each area 61 to 63, but if the developed image pattern is less than one page, The process returns to step Sll.Furthermore, once the image pattern has been developed for one page, it will be synthesized and output using the output colors shown in each area 61 to 63 in step S19.

[Second Embodiment (Figure 7)] In the above explanation, when editing a document, a code based on the editing process (deletion, insertion) is inserted, and the editing code is recognized at the time of printout. Although the character strings between the codes are color-coded, the present invention is not limited to this. In other words, the re-edited document information (stored in the RAMS) and the original document (stored in the magnetic disk device 4) can be edited without inserting the aforementioned edit code.
You can identify inserted or deleted strings by comparing them.

The following explanation is an example (FIG. 7) in which the original document in the magnetic disk device 4 and the edited document are compared and printed out. In addition, in order to compare the original document and the edited document, RA
Areas for pointers P and Q were provided at predetermined positions within M5. Pointer P indicates the first clause position of the original document as an initial value, and pointer Q indicates the first clause position of the edited document.

Now, in step Sit, it is first determined whether the pointer Q indicates the end of the edited document. Pointer Q
When indicates the last clause, the process moves to step S24, and it is determined whether the pointer P indicates the last clause of the original document. If this judgment is ``YES'', it means that there is no phrase to compare, so the process ends; however, if the judgment is ``No'', the phrase group (character string) of the original document after pointer P is It is determined that the character string has been deleted, and deletion character string processing (expansion processing to the red image area 62) is executed for the character string (step 525).

Further, if it is determined in step Sll that the pointer Q indicates a clause in the middle of the edited document, step Sll
At step 12, it is determined whether the pointer P points to the last clause of the original document. In the case of "YES", the process moves to step S26, and it is determined that all character strings after the clause indicated by the edited pointer Q are inserted (in this case, it means addition) character strings, Insert character string processing (expansion processing to the blue image area 63) is performed on the character string.

Now, if it is determined in step S12 that the pointer P indicates a clause in the middle of the original document, the processing from step 313 onwards will be performed (that is, in step S13
The following processing is performed using pointer P.

This process is performed when it is determined that both Q and Q indicate intermediate clauses in their respective documents).

In step S13, first, the clauses indicated by pointers P and Q are read from their respective storage locations. Next step S14
Compare each other's clauses. If it is determined that they are the same clause, it means that no correction processing such as deletion has been performed on the clause indicated by the pointer Q, so the character string is developed in the black image area 61 (normal character string In the next step S27, the pointers P and Q are moved to the next phrase, and the process returns to step Sit.

If the determination in step S14 is "No" (the read phrases do not match), the process moves to step S15. In step S15, the original document after the pointer P is searched for the same phrase as the phrase indicated by the pointer Q (edited document). When the same phrase is searched, the process moves from step S16 to step 318, and the next phrases in both documents are respectively read. If the read phrase is also the same, it can be determined that the phrase of the pointer Q that is currently being watched is a deleted character string, and the process moves from step S19 to step S20 to execute deleted character string processing. Next, the process moves to step S23 and the pointer Q
and pointer P to the next clause, respectively, and step Sl
Return to l.

Also, the determination in step S16 or step S19 is N.
O'', the process goes to step S17, and since it can be determined that the clause indicated by the pointer Q is an inserted character string, insert character string processing is executed, and only the pointer Q is inserted in step S22. Update to next clause.

When the above-described processing is executed for each page of the edited document, composite printing processing is performed for each color as in the first embodiment. Therefore, according to this second embodiment, by comparing the edited document and the original document before editing,
There is no need to insert insertion start/end codes and the like together with the inserted character string during editing. Note that in the second embodiment described above, the original document and the edited document were compared on a clause-by-phrase basis, but it is clear that comparisons may be made on a character-by-character basis. still,
In that case, even if the characters are determined to be the same, it is desirable to compare several characters after that character.

In addition, in the example, the storage location of the edited document and the original document is RA.
M. Although the explanation has been made using a magnetic disk, there is no problem even if the original document is also read into the RAM and processed. Rather,
In this case, the comparison processing speed will be improved.

[Description of Third Embodiment] Although the printer in the above explanation has been described as having a function of color compositing three areas, the present invention is not limited to this.

For example, it may be applied to a dot matrix type printer equipped with yellow (Y), magenta (M), cyan (C) and black ink ribbons. Normally, when print data is sent to this type of printer, a color designation code is added to the beginning of a desired character string code data group or image data in the print data. Upon receiving this data, the printer selects the ribbon corresponding to the color designation code and prints it. In the following explanation, in order to simplify the explanation, it is assumed that the printer receives and prints character symbol codes.

Now, in order to obtain the output image shown in FIG. 3(b) (with the deleted character string in red and the inserted character string in blue) using such a printer, the image memory 6 is not necessarily required. This is because, in the case of the first embodiment, the deletion start code in the edited document data (FIG. 4) stored in the RAM 5 is a red printed code, the insertion start code is a blue printed code, and furthermore, the deletion/insertion This is because it is sufficient to convert each end code into a black print code and output it to the printer side.

Also in the case of the second embodiment, it is sufficient to insert a red print code in front of a character string determined to be a deleted character string and output it.

[Description of Fourth Embodiment (FIG. 8)] Furthermore, in the three embodiments described above, only the printing of edited character strings in different colors based on the type of editing processing was explained. This also does not limit the invention.

For example, Fig. 8 shows an example of the output image, and as shown in the figure, character strings are usually deleted by hand (double lines in the figure).
This is because it is also possible to print in exactly the same way as to insert or insert (the character string ``tachitsuteto'' and the accompanying insertion mark in the figure). In this case, when developing the character pattern in the image memory 6, the double line pattern is logically added onto the deleted character string, and furthermore, the double line pattern is developed above or below the insertion point of the inserted character string. This can be easily achieved by expanding the inserted character string and insertion mark and outputting it to a printer. Therefore, in this case, it can be achieved even with monochrome printing.

In addition, it is obvious that the character string after editing may be identified by the types of hatching and ruled lines, or by adding colors to them, and by a combination of these.

Note that in the editing process in the embodiment, only the deletion/insertion process has been described, but the present invention can also be applied to, for example, correction process. In this case, this can be achieved by coloring the character string before correction or clearly indicating it with parentheses, etc., and inserting the corrected character string before and after it.

Furthermore, although the above-described embodiments have been described only for printed documents, it is of course possible to perform the same processing when displaying on a display screen such as a CRTl.

As explained above, according to this embodiment, it is possible to clarify the character string edited by the editing process.

[Effects of the Invention] As described above, according to the present invention, it is possible to clarify a character string edited by editing processing.
