Abstract

PURPOSE:To attain the conversion of a character code as desired even if the character code to be converted includes an unconvertible character. CONSTITUTION:If the character data on the address of an unconverted document data storage part pointed by a pointer is not prescribed by a JIS code (S43), the character data is converted into the corresponding JIS code string by referring to a conversion table registered previously at a conversion table storage part (S46). Then the normal MS/DOS conversion is carried out to the JIS code string, and the converted code string is automatically written into a converted document data storage part through a CPU (S44).

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 which makes it possible to use document data between models having different character codes.

[0002]

2. Description of the Related Art For example, document data created by a Japanese word processor is used as an MS-DOS for a personal computer.
If you want to use it with a compatible word processing application, or vice versa, if you want to use the document data created by the application with a Japanese word processor, it is necessary to convert the created document data to the model of the destination, that is, the character code. Is.

Therefore, some conventional Japanese word processors have an MS-DOS conversion function so that document data can be easily shared with a personal computer. Also, a conversion application with a character code of a Japanese word processor has been developed for a personal computer.

[0004]

However, in the applications of each Japanese word processor or personal computer, it is possible to input characters other than the unique JIS code or character symbols created by the user. Characters are not unified with other models or other applications.

Therefore, conventionally, for example, when document data of a Japanese word processor is converted by MS-DOS conversion,
Due to the difference in the character set, it was not possible to correctly convert other than JIS code, and external characters and characters not specified in JIS were blank or garbled.

For example, as shown in FIG.
MS-DOS conversion of documents that contain characters other than codes (“(Ltd.)” with the size of one character, numbers surrounded by circles (hereinafter referred to as circled numbers), and “Heisei” made with half-width Kanji Then, the characters other than the JIS code are as shown in FIG.
6 is converted into a blank, or as shown in FIG. 6C, the character is converted into a character other than the JIS code (in this case, "*").

Therefore, since the contents of the document are changed in this way, it is necessary to edit the document again after the conversion.

This is because there is a character that cannot be converted in the character code to be converted.

If the character code to be converted includes a character that cannot be converted, if the character code can be converted to the character code to be converted, the document needs to be edited again after the conversion. It is clear that it will disappear.

An object of the present invention is to make it possible to convert a character that cannot be converted into a character code to be converted into a character code to be converted.

[0011]

The means of the present invention are as follows. The storage unit 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) stores the document data created with the first character code. The first conversion unit 2 converts the document data created by the first character code stored in the storage unit 1 into the document data of the second character code. The conversion information storage means 3 stores the character data of the first character code that cannot be converted from the first character code to the second character code in association with the character data of the convertible second character code. .. The detecting means 4 converts the first character code into the second character code by the first converting means 2,
A character code that cannot be converted from the first character code to the second character code is detected. The second conversion unit 5 refers to the conversion information storage unit 3 for the character data of the first character code detected by the detection unit 4,
Convert to the character data of the second character code.

[0012]

The operation of the means of the present invention is as follows. The detection unit 4 detects a character code that cannot be converted from the first character code to the second character code when the first conversion unit 2 converts the first character code to the second character code. In this case, the second conversion means 5 converts the character data of the first character code that cannot be converted from the first character code into the second character code into the character data of the convertible second character code. By referring to the conversion information storage means 3 stored in association with each other, the character data of the first character code detected by the detection means 4 is converted into the character data of the second character code. Therefore, if there is a character that cannot be converted in the character code to be converted, it can be converted into the character code to be converted, and it is not necessary to edit the document again after the conversion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 2 is a block configuration diagram of the document data conversion apparatus of the embodiment. In the figure, reference numeral 10 is a CPU (central processing unit) which controls the entire control. Reference numeral 20 is an input unit such as a keyboard, and 30 is an input control unit for controlling the input unit 20. Reference numeral 40 is a display unit such as a CRT display, and 50 is a display control unit for controlling the display unit 40. Reference numeral 60 is a memory having a pre-conversion document data storage unit 62, a conversion table storage unit 64, and a post-conversion document data storage unit 66.

The input unit 20 has a data input key 22 for inputting document data, a table data input key 24 for registering characters other than JIS code with a character string of only JIS code, and an MS-DOS conversion command. It has a plurality of input keys such as an MS-DOS conversion command key 26 for giving, and outputs a corresponding key operation signal to the input control section 30 in response to a key input operation of each of these input keys. The input control unit 30 converts the key operation signal input from the input unit 20 into a predetermined code and holds it.

The CPU 10 sequentially accesses the codes held in the input control unit 30. If the accessed codes are document data, the codes are stored in the pre-conversion document data storage unit 62 of the memory 60 in a corresponding manner. The data is stored and output to the display control unit 50. Display controller 50
Converts the input data into display control data, outputs it to the display unit 40, and causes the display unit 40 to display it.

When the accessed code is data for registering a character other than the JIS code corresponding to the key operation of the table data input key 24 with a character string of only the JIS code, the CPU 10 handles them. In the conversion table storage unit 64 of the memory 60.

Further, when the input control section 30 gives an MS-DOS conversion command, the CPU 10 stores the pre-conversion document data stored in the pre-conversion document data storage section 62 of the memory 60 into the conversion table storage section 64. Conversion is performed while referring to the stored conversion table, and the result is stored in the converted document data storage unit 66.

Here, any or all of the pre-conversion document data storage unit 62, the conversion table storage unit 64, and the post-conversion document data storage unit 66 of the memory 60 are configured as an external storage unit such as a floppy disk (not shown). You can also do it.

The operation of the document data conversion device having the above configuration will be described below. FIG. 3A is a flowchart of a conversion table creating operation executed in response to a key operation of the table data input key 24 of the input unit 20. That is, when the key 24 is operated, a pointer (not shown) is first reset (step S31). Then, it is determined whether or not the character data is stored in the address designated by the pointer in the pre-conversion document data storage unit 62 of the memory 60, that is, whether the document is the end (step S32).

If the character data is stored, then the character data is taken out and it is judged whether or not the character data is the data defined by the JIS code (step S3).
3). If the character is a JIS code character, the pointer is updated (step S34), and the process returns to step S32. However, if the character is not a JIS code character, that character is displayed on the display unit 40 (step S35), and the above step S
Proceed to 34.

When the determination of all the character data of the pre-conversion document data stored in the pre-conversion document data storage unit 62 is completed in this way, as shown in FIG.
A list of characters other than JIS code can be obtained. Therefore, next, what kind of J
By operating the document data input key 22 to input whether to convert to the IS code character data (step S
36), a conversion table as shown in FIG. 3B is created and stored in the conversion table storage unit 64.

Next, when the MS-DOS conversion command key 26 is operated, the conversion operation according to the flowchart shown in FIG. 4 is executed. That is, first, the pointer designating the address of the pre-conversion document data storage unit 62 is reset (step S41). Then, it is determined whether or not the character data is stored at the address designated by the pointer in the pre-conversion document data storage unit 62, that is, whether or not it is the end of the document (step S42).

If it is not the end of the document, the character data is retrieved from the pre-conversion document data storage unit 62, and the character data is J
It is determined whether the data is the data defined by the IS code (step S43). If it is a character of JIS code, perform conversion through normal MS-DOS conversion,
The converted document data storage unit 66 is written (step S4).
4). After that, the pointer is updated (step S4
5) and returns to step S42.

However, if the character is a character other than the JIS code, the conversion table previously registered in the conversion table storage unit 64 is referred to and converted into the corresponding JIS code string (step S46), and then the above step S44. Go to
MS-DOS conversion is performed.

When the conversion processing for all the character data of the pre-conversion document data stored in the pre-conversion document data storage unit 62 is completed in this way, the post-conversion document data storage unit 66 stores, for example, the pre-conversion document. In the case of the document as shown in FIG. 6A, the document converted as shown in FIG. 5 is stored. Therefore, the same document as the document content before conversion can be converted to MS-DOS.

That is, before performing MS-DOS conversion, J
Characters other than the IS code are represented by a character string consisting of only the JIS code and registered, and when a character other than the JIS code is present in the document when MS-DOS conversion is executed, it is converted to the registered character string. Since the document data conversion device has the function, the same document contents as before conversion can
-It becomes possible to do DOS conversion.

In the above embodiment, the case of MS-DOS conversion has been described, but the present invention can be applied to all devices and functions for exchanging document data with different character sets, such as communication. ..

Further, in the above embodiment, the conversion table is created before the MS-DOS conversion is executed, but the conversion table created in advance may be provided in the form of ROM or the like.

[0029]

According to the present invention, when there is a character that cannot be converted in the character code to be converted, it can be converted into the character code to be converted. Therefore, it is not necessary to edit the document again after the conversion, and the operation after the conversion can be made unnecessary.
