Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document data conversion device for converting document data created in one format into document data in another format.

[0002]

2. Description of the Related Art Recently, word processing software (hereinafter referred to as word processing software) operating on an information processing device such as a word processor or a personal computer has come to be used daily as a tool for creating a document. There is. These word processors or word processing software (hereinafter collectively referred to as word processors) have functions for creating, editing, printing, and saving documents, and individuals can easily create various documents.

This word processor has been commercialized by a plurality of manufacturers, but the document data to be created has a format unique to each company, and is currently poor in compatibility. Even if the products are manufactured by the same manufacturer, compatibility may not be maintained depending on the model.

In reality, in many cases, word processors of different companies are mixedly used in the office. In this case, incompatible document data can be used by each other's word processors. It will be necessary to work to convert the format. Recently, software having a function of converting the format of such document data and a word processor having the function (hereinafter, collectively referred to as a document conversion device) are also commercially available. Is becoming.

[0005]

The document data created by the word processor is mainly composed of format, character, ruled line, graphic, and image data. Among these data, data such as characters, ruled lines, and formats have almost the same specifications of each company, and conversion is easy.
However, the specifications of graphics and image data vary from company to company, and the basic structure of the data is often completely different. Therefore, it is almost impossible to completely convert the document data including the graphic or image data created by the word processor of company A into a format that can be used by the word processor of company B. is there.

FIG. 13 shows such a concrete example. FIG.
Document data 10 shown in 3 (a) is created by the company A, and this document data 10 includes image data 12 (image of a woman sliding on skis) input as a figure.

When such document data 10 is converted into document data 20 in a format conforming to the standard of the word processor of company B by a conventional document conversion device, characters,
Although the ruled lines and the format data can be converted correctly, the image data 12 cannot be converted correctly so that the word processor of the company B can read them.
As shown in (b), the image data 10 has been deleted from the converted document data 20.

Further, even if it seems that the characters and the ruled line data are correctly converted at first glance, there are cases where the characters are garbled. In such a case, after the document data conversion, it is necessary to perform a check operation to compare the pre-conversion sentence and the post-conversion sentence one by one. In this case, when the volume of the document data is large, it takes a lot of time and labor, so that there is a problem that the work efficiency is significantly reduced.
In addition, human error often occurs during the above checks, which is also a problem in terms of work quality.

An object of the present invention is to make it possible, when converting document data into another format, to extract or inform the user of data that is not converted correctly in the format conversion.

[0010]

The present invention comprises the following means. The document data format conversion means converts the format of the document data into the designated format.

The format conversion function information storage means stores information about the format conversion function of the document data format conversion means. This format conversion function information includes, for example, characters, formats, ruled lines, figures,
And information indicating whether or not it is possible to convert from one format to another format for each type of data such as an image.

The unconvertible format data extracting means converts the unconvertible type data in the specified document data when the document data format converting means converts the specified document data into the specified format. , Based on the information stored in the format conversion function information storage means.

Further, the data of the type which has not been subjected to the format conversion and which has been extracted by the extracting means may be output to the outside by an output means such as screen display or print output.

[0014]

According to the present invention, the format conversion function information storage means stores information relating to the format conversion function of the document data format conversion means.

The document data format conversion means converts the format of the document data into a designated format. At this time, the format unconvertible data extraction means converts the unconvertible type data in the designated document data. , Based on the information stored in the format conversion function information storage means.

Therefore, when the format of the document data is converted, the type of data that cannot be converted in the document data (for example, character data, format data, ruled line data, graphic data, or image data)
Only can be extracted.

Further, output means is added to the above-mentioned configuration, and the data which has not been subjected to the format conversion in the designated document data extracted by the format unconvertible data extracting means by the output means is displayed, for example, on a screen or If the printout is output to the outside, the user can know whether or not the document data designated by the user has been correctly subjected to the format conversion function. Further, in this case, it is possible to know which type of data was not format-converted.

The black rectangle 111 shown in FIG. 3A is a cursor.

In response to this message, the user inputs the name of the original conversion document data 81 to be converted called "ski member recruitment 1" as shown in the screen of FIG. 3 (b). Then, the carriage return, which is the enter key, is pressed. Then, next, a message "Please input the document name of the conversion destination" is displayed at the bottom of the screen. After confirming this message, the user inputs the name of the conversion destination document data 82 of "recruitment of ski staff 2" following the display of "conversion destination document name:". Then, in the same manner as above, the carriage return, which is the enter key, is pressed. Then, as shown in FIG. 3C, a message "Please input the unconverted document name" is displayed at the bottom of the screen.

In response to this message, the user inputs the document name of the unconverted document data 83 "recruitment of ski staff 3" as shown in the screen of FIG. 4 (d). When this input is completed, the message "Convert document (execute / cancel)" is displayed at the bottom of the screen. After this message is displayed, the user can display the conversion source document name (the document name of the conversion source document data 81), the conversion destination document name (the document name of the conversion destination document data 82), and the unconverted document name (the unconverted document). It is confirmed whether all the input of the document name of the data 83) is correct. When all the inputs are correct and the conversion of the document data having the document name "Ski Staff Recruitment 1" input as the conversion source document name is to be converted, the carriage return is pressed.

When the carriage return is input, a message "Document conversion in progress" is displayed at the bottom of the screen as shown in FIG. 4 (e). When the document conversion process is completed, a message "Document conversion completed" is displayed at the bottom of the screen as shown in FIG. 4 (f) to notify the user that the document conversion process is completed.

After the document conversion is completed, the data which is not correctly converted in the conversion source document data 81 designated by the conversion source document name is stored in the external storage device 80 as the unconverted document data 83. Then, the unconverted document data 83 is displayed on the screen of the display unit 90, for example, according to a user's instruction. On the other hand, in the conversion source document data 81, the correctly converted data is the conversion destination document data 82.
Is stored in the external storage device 80.

FIG. 5 is a diagram showing an example of a case where the conversion source document data 81 is subjected to document conversion (format conversion) by performing the above operation. FIG. 5A is a diagram showing the contents of the conversion source document data 81 having the document name “ski member recruitment 1” created by the word processor of Company A. As shown in FIG. 7A, the document data 81 of “recruitment of ski staff 1” is
The image data 123 is included in addition to the character data and the ruled line data.

When the conversion source document data 81 is converted into the document format (document format) of the word processor of company Z with the document name "recruitment of ski staff 2", it is assumed that the image data 123 cannot be converted correctly. . In this case, as shown in FIG. 5B, the data (eg, format data, character data, ruled line data, graphic data) correctly converted into the document format of the word processor of Company B is used as the conversion destination document data 82. Created. The conversion destination document data 82 does not include the image data 123. The image data 123 that cannot be correctly converted to the Z company format is created as unconverted document data 83 as shown in FIG. Then, the content of the unconverted document data 83 is displayed on the screen of the display unit 90 along with, for example, an error display.

Next, the processing operation of this embodiment will be described. FIG. 6 is a general flowchart for explaining the overall operation of this embodiment. First, the user inputs the names of the conversion source document data 81, the conversion destination document data 82, and the unconverted document data 83 as document conversion information. Also,
As information that indicates the format to be converted,
For example, the company name (company A, company B, ...) Is also input by the user (S1). This user input is input through the user input screen shown in FIGS.
Made from.

Next, the conversion source document data 81 whose name is designated by the user is read from the external storage device 80, and the data which has been converted into the format designated by the user in the conversion source document data 81 is The conversion destination document data 82 is collected into one. Then, the conversion destination document data 82 is stored in the external storage device 80.
In addition, in this document conversion, data that cannot be properly converted in format is collected as unconverted document data 83 and stored in the external storage device 80. The unconverted document data 83 is stored in the original format (S2).

Subsequently, when the unfinished document data 83 is generated in the process of step S2, the unfinished document data 83 is read from the external storage device 80, and information (data of the data) about the unconverted document data 83 is read. The content or the type of data) is displayed on the screen of the display unit 90 (S
3).

FIG. 7 is a flow chart for explaining the operation of the document data conversion execution processing of step S2 of FIG.
This document data conversion execution processing is roughly classified into a first format conversion processing (S11), a data conversion possibility discrimination processing (S12), and a second format conversion processing (S12).
13), and the above steps S11, S12, S13
The processing is executed in the order of.

In the first format conversion process of step S11, various types of data forming the conversion source document data 81 are converted into a predetermined uniform document format. By this processing, the source document data 81 which is not unified in each company is once converted into the unified format.

In the next step S12, the data conversion propriety discrimination processing, by referring to the document data conversion propriety table 410, the format and characters forming the conversion source document data 81 converted into the unified format as described above. It is determined whether each type of data of ruled lines, figures, and images can be converted into the format of the company specified by the user. Then, the conversion source document data 81 converted into the unified format is divided into convertible document data (convertible document data) and unconvertible document data (non-converted document data).

Further, in the second format conversion process of the next step S13, the convertible document data is converted into the format of the specified company. on the other hand,
The non-converted document data is converted to the original format.

Details of the first format conversion process in step S11 of FIG. 7 will be described with reference to the flowchart of FIG. In this process, first, CP
U30 reads the conversion source document data 81 designated by the user from the external storage device 80. Then, the conversion source document data 81 is analyzed and the conversion source document data 8
It is determined which company the format 1 belongs to (S111).

Then, a program (document format conversion program) for converting the conversion source document data 81 created in the format of the determined company into unified document data is selected (S112). These document format conversion programs are stored in the first document format conversion program table 420 shown in FIG. 9 in the document data conversion program 41, for example.

Next, the CPU 30 executes the selected document format conversion program to convert the designated conversion source document data 81 into a unified format.
(S113) By the above processing, the conversion source document data 81 is, for example,
Format data, character data, ruled line data, graphic data, and image data are categorized in the format shown in FIG. 10 and converted into a unified format. For example, the conversion source document data 81 is managed as a single file, for example.

Further, subsequently, details of the data conversion propriety discrimination processing of step S12 of FIG. 7 will be described with reference to the flowchart of FIG. In this process, CP
The U30 first clears the conversion destination document data 82 on the external storage device 80 (S121).

Next, the unconverted document data 83 in the external storage device 80 is also cleared (S122). Furthermore, the type of each data in the conversion destination document data 81 (format, character,
The pointer X indicating a ruled line, figure, or image is cleared to "0" (S123). This pointer X is, for example,
It is set in a predetermined register built in the CPU 30.

Further, the pointer X is: when X = “0”, format data X = “1”, character data X = “2”, ruled line data X = “3”, graphic data X When “= 4”, it is an index indicating image data.

In the following description, the data (X)
In the conversion source document data 81 after conversion to the uniform format, when X = “0”, uniform format data X = “1”, uniform format character data X = “2”, Unified format ruled line data X = “3”, unified format graphic data X = “4”, unified format image data.

Next, the CPU 30 causes the conversion source document data 81
Format is used as a key and the "company name" indicating the format of the conversion target document data 81 to be converted is used as a key to search the format conversion information in the document data conversion availability table 410, and the data (X X = 0,
It is determined whether each type of data (1, 2, 3, 4) can be converted into a specified format (S124,
S125).

When the format of the data (X) can be converted (S125, OK), the data (X) is added to the conversion destination document data 82 on the external storage device 80 (S).
126). On the other hand, if the data (X) cannot be converted in format (S125, NG), the data (X) is added to the unconverted document data 83 in the external storage device 80 (S12).
7). The above steps S124 to S127 are repeated while incrementing the value of the pointer X by "1" (S128), and until it is determined that the value of the pointer X is "5" or more (S129, YES). That is,
The value of pointer X. The processing of the above steps S124 to S127 is repeated while sequentially increasing from "0" to "4".

By the above processing, the format, characters, ruled lines,
Of the various types of data of figures and images, data that can be converted into a specified format is stored as conversion destination document data 82 in the external storage device, and data that cannot be converted into the specified format is unconverted document data 83. Is stored as

Details of the second format conversion processing in step S13 of FIG. 7 will be described with reference to the flowchart of FIG. In this process, first, CP
U30 is a document conversion format conversion program for converting the conversion destination document data 82, that is, the document data currently in the unified format, which can be converted into the format corresponding to the company name specified by the user, into the specified format. Is selected (S131). This document format conversion program is stored in the first document format conversion program table 420 in the format shown in FIG. 13 in the document data conversion program 41, for example.

Subsequently, the CPU 30 executes the selected document format conversion program to convert the conversion destination document data 82 of the specified uniform document format into a format corresponding to the specified company name. Then, the converted document data 82 after conversion is stored in the external storage device 80 (S132).

Next, the CPU 30 sends the unconverted document data 8
3, that is, the document conversion format conversion program for converting the document data currently in the unified document format, which cannot be converted into the format corresponding to the company name specified by the user, into the original format. Document format conversion program table 43
Select from 0 (S133).

Subsequently, the CPU 30 executes the selected document format conversion program to restore the unconverted document data 83 from the unified document format to the original format. Then, the unconverted document data 83 after this conversion is converted into
The data is stored in the external storage device 80 (S134).

By the above processing, the conversion destination document data 82
Is converted into a format corresponding to the company name specified by the user. On the other hand, the unconverted document data 83 is returned to the original format.

As a result, for example, in the present embodiment,
Document data created by the word processor of Company Z can be
If you try to convert it to a format that can be used by the word processor of the company, the data of the format, characters, ruled lines, and graphics will be converted to the format according to the standard of the company B.
No format conversion is performed on the image data (see the document data conversion availability table 410 in FIG. 2).

For the data that cannot be converted in format, for example, the content is displayed on the display unit 90 to notify the user. Further, in the case where the printer is provided, instead of the screen display, the content of the data whose format cannot be converted may be printed out on paper.

In the above embodiment, the conversion source document data 8
Data that cannot be converted to the specified format out of 3 is also converted to the unified document format once. However, data that cannot be converted to the specified format remains unconverted document data. You may make it extract as.

Further, in the present embodiment, the document conversion device mounted on the word processor is taken up, but when the document data is transferred between the word processor of another model and the information processing device also in the communication software. In addition, there is also something that will automatically convert to a format that can be used by the destination model. The present invention is also applicable to such communication software. In this case, for example, the transfer source device may be notified of the information about the data that cannot be converted into the specified format from the transfer destination device. Then, the transfer destination device may notify the user of the data whose format cannot be converted based on this information by screen display or print output.
