Abstract

PURPOSE:To easily read out an outputted character string by converting an inputted character code for an external character into a character font or a character code expressing a similar character or reading. CONSTITUTION:When the character code of an external character is received, an external character processor accesses to a similar character table 2A. When a similar character is stored in the table 2A a similar character font is outputted. When no similar character is stored in the table 2A, a registered 'KANA' (Japanese syllabary) character table 2B is accessed and a corresponding 'KANA' character is read out and converted into a character font. When no corresponding 'KANA' character is stored in the table 2B, the whole character string including the external character is converted into 'KANA' characters. When a word registered in a registered word table 2C exists in the converted 'KANA' character string, the registered word is substituted for the word part. Since no unreadable character is included in an outputted character string, the character, string can easily be read out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An external character processing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an external character processing device according to this embodiment. In FIG. 1, reference numeral 1 is a control unit, 2A is a similar character table, 2B is a registered kana character table, and 2C.
Is a registered word table, 3 is a character output unit, and 4 is a character font memory.

The control unit 1 controls the operation of the entire apparatus, receives a character code (a character code signal indicating a character code) from an external apparatus, accesses the character font memory 4, and accesses a corresponding character font (indicates a character font). A character font signal) is supplied to the character output unit 5. The control unit 1 is composed of, for example, a microprocessor and its peripheral circuits.

As shown in FIG. 2, the similar character table 2A stores character codes of external characters and character codes of characters similar thereto in a one-to-one relationship. Registered kana character table 2
As shown in FIG. 3, B stores the character code of the external character and the character code of the kana character corresponding to it. Note that there may be a plurality of corresponding kana characters instead of only one. Which of the plurality of candidates is selected is grammatically selected from the character strings before and after the external character using a word dictionary or the like. As shown in FIG. 4, the registered word table 2C is a table in which, for example, "corporation", "school corporation", etc. are registered as prefixes and suffixes of proper nouns and the like. The character output unit 3 outputs the supplied character font by a display device, a printer or the like. The character font memory 4 stores a pair of character code and character font.

Next, the operation of the external character processing device shown in FIG. 1 will be described with reference to FIGS.

Character codes are sequentially supplied to the control unit 1 from an external device. The control unit 1 accesses the character font memory 4 using the supplied character code as a key. When the corresponding character font is stored in the character font memory 4 (“No” in step S1), the control unit 1
Reads out the character font (step S9) and supplies it to the character output unit 3. The character output unit 3 displays the supplied character font on the display device and causes the printer to print.

When the character font corresponding to the supplied character code is not stored in the character font memory 4 ("Yes" in step S1), the character code is a so-called external character code, and the control unit 1 Refers to the similar character table 2A.

When the character code of the character similar to the character designated by this character code is stored in the similar character table 2A (in the case of "yes" in step S2), the control unit 1 determines the character code of the similar character. Is read (similar character output process, step S3). The control unit 1 reads the character font of the similar character from the character font memory 4 (step S9) and supplies it to the character output unit 3.

On the other hand, when the character code of the similar character is not stored in the similar character table 2A ("No" in step S2), the control section 1 refers to the registered kana character table 2B. When the character code is included in the registered kana character table 2B, the character code is replaced with the character code of the corresponding kana character (kana character correspondence process, step S5). When there are a plurality of corresponding kana character candidates, one candidate is grammatically selected from the character strings before and after the external character using a word dictionary (not shown) or the like. Control unit 1
The character code of the kana character is converted into a corresponding character font (step S9) and supplied to the character output unit 3.

On the other hand, when the supplied character code is not included in the registered kana character table 2B ("No" in step S4), the entire character string including the external character is replaced with the kana character string (kana). Character conversion process, step S
6).

Further, referring to the registered word table 2C, it is judged whether or not there is the same kana character string as the registered word in the replaced kana character string (step S7).
If there is a character string that matches the word stored in the registered word table 2C in the kana character string (“Yes” in step S7)
In this case), the control unit 1 replaces the matching portion with the registered word (registered word replacement process, step S8). The control unit 1 obtains a character font corresponding to the obtained character code by accessing the character font memory 4 and outputs it to the character output unit 3 (step S9).

The character output unit 3 displays and prints the supplied character font. The document output by the character output unit 3 does not include unreadable characters or symbols.

Next, the above-mentioned operation will be specifically described by taking as an example the case where the character code of the character string shown in FIG. 6 is supplied to the control unit 1. In the examples (A) to (F) shown in FIG. 6, it is assumed that the underlined characters are so-called external characters and the character font corresponding to the character font memory 4 is not stored.

In the case of the example (A), as shown in FIG. 2, the character "high" similar to the external character is stored in the similar character table 2A. Therefore, the control unit 1 determines “Yes” in steps S1 and S2, reads the character code of the similar character “high” from the similar character table 2A in step S3, and converts it into a character font in step S9. , Character output section 3
Supply to. The character output unit 3 outputs "Takahashi Shoten" instead of the character string of the example (A).

Similarly, in the case of the example (B), it is determined "Yes" in steps S1 and S2, the character code of the similar character "KU" is read from the similar character table 2A in step S3, and this is read in step S9. Converted to character font,
It is supplied to the character output unit 3. The character output unit 3 outputs "country club" instead of the character string in the example (B).

In the case of the example (C), it is assumed that similar characters are not stored in the similar character table 2A. In this case, the control unit 1 determines "Yes" in step S1 and "No" in step S2, and refers to the registered kana character table 2B. As shown in FIG. 3, since "Min" exists as a kana character corresponding to the external character, the control unit 1 determines "Yes" in step S4, and reads out the character code of "Min" (step S5). This is converted into a character font (step S9) and supplied to the character output unit 3. The character output unit 3 outputs "Min come" instead of the character string in the example (C).

In the case of the example (D), since the similar character does not exist in the similar character table 2A, "Yes" in step S1.
In step S2, it is determined to be "no", and the control unit 1 refers to the registered kana character table 2B. Since “2” exists as the kana character corresponding to the registered kana character table 2B, the control unit 1 determines “Yes” in step S4,
The character code of "2" is read (step S5), converted into a character font (step S9), and supplied to the character output unit 3. The character output unit 3 outputs "part 2" instead of the character string of the example (D).

In the case of the example (E), it is assumed that the similar character is not stored in the similar character table 2A and the corresponding kana character is not stored in the registered kana character table 2B.
In this case, it is determined to be "yes" in step S1 and "no" in steps S2 and S4, and the character code of the character string including the external character is converted to the character code of "Yuzariyouten" in step S6. There are no words registered in the registered word table shown in FIG. 4 in this character string. Therefore, in step S7
Is detected, the control unit 1 converts the character code of this Kana character string into a character font (step S
9), and supplies it to the character output unit 3. The character output unit 3 outputs "Usariyouten" instead of the character string in the example (E).

In the case of the example (F), it is assumed that the similar character of the external character does not exist in the similar character table 2A and the corresponding kana character does not exist in the registered kana character table 2B. In this case, "Yes" in step S1, "No" in S2 and S4
In step S6, the character code of the character string including the external character is converted into the character code of the kana character “Dokubakubushiki Gaisha”. The kana character string of the word "corporation" registered in the registered word table 2C shown in FIG. 4 exists in this character string. Therefore, "Yes" is detected in step S7, and the character code of the kana character string "Kabushiki Gaisha" is converted to the character code of "corporation" (step S).
8). Finally, the control unit 1 converts the character code of "Dokubo Co., Ltd." into a character font (step S9) and supplies it to the character output unit 3. Therefore, the character output unit 3 is an example (D).
Instead of the character string of, "DOBOKU CORPORATION" is output.

The present invention is not limited to the above embodiment. For example, when there is a similar character, the similar character output processing is performed, and in other cases, the external character is replaced with a special symbol and output. You may make it perform a process (special symbol replacement process). Such an embodiment will be described with reference to the flowchart of FIG.

In this embodiment, as shown in FIG. 7, when the supplied character code is the external character code, the control unit 1 refers to the similar character table 2A. When the character code of the character similar to the character designated by this character code is stored in the similar character table 2A (in the case of "Yes" in step S2), the control unit 1 reads the character code of the similar character (step S3). ), The character font of the similar character is read (step S9), and the character output unit 3
Supply to.

On the other hand, when the similar character is not stored in the similar character table 2A ("No" in step S2), the control unit 1 changes the character code to a special symbol, for example, a character code of "*". Replace (Special symbol replacement process,
In step S10), the character font of this special character is supplied to the character output unit 3. For example, in the case of the character string of the example (F) of FIG. 6, the output of the character output unit 3 is “* Ki Co., Ltd.”.

External character part is deleted and output (deletion process)
It is also possible. In this case, the output of the character output unit 3 is
For example, in the case of the example (F) of FIG. 6, it becomes "Ki Corporation" and "Ki Corporation".

Similar character output processing described above (step S
3), which of the kana character correspondence process (step S5), kana character conversion process (step S6), registered word replacement process (step S8), and special symbol replacement process (step S10) is selected and in what order? It can be appropriately selected and set according to the requirements of the system.

For example, when a character code of an external character appears, the registered word replacement process (step S8) is first performed on the kana character string corresponding to the character string including the external character, and then the kana character correspondence process (step S5), similar. It is also possible to perform the character output process (step S3). In this way, the external character processing procedure suitable for the system requirements can be arbitrarily selected and set, so that it is possible to perform the appropriate external character processing.

Further, an input device such as a keyboard may be connected to the control unit 1 so that the execution order of each process can be changed according to the instruction of the input device. For example, in FIG.
It is also possible to arbitrarily set the path from step S1 to step S4 or S6 and not perform the similar character output process (step S3).

It is also possible to replace the character string including the external character with another character string such as Roman characters and output. It is also possible to output in a half-width character string so that the output character string does not increase. For example, in the case of the example (A) of FIG. 6, “TAK
You may output as "AHASI store" or "TAKAHASI store".

Further, according to the external character processing method of the present embodiment, the characters are displayed or the print color is changed or shaded so that the operator can identify which character is the character processed by the external character. You may do it. FIG. 8 shows an example in which characters processed by the external character processing method of this embodiment are displayed in a shaded manner. As a result, the operator can accurately determine the external character in the document.

In the above embodiment, the control section 1 receives the character code and outputs the character font. However, the present invention is not limited to this, and the control unit 1 may receive the character code, convert the character code of the external character into the character code of the similar character or the character code of the character representing the reading, and output the character code.

The configuration in this case is shown in FIG. In FIG. 9, the registered character memory 14 stores a list of previously registered character codes (character codes of characters other than external characters), and does not store character fonts. When the character code is supplied from the outside, the control unit 1 accesses the registered character memory 14 and the supplied character code is stored in the registered character memory 14.
If the character code is stored in
Supply to 3.

On the other hand, when the supplied character code is not stored in the registered character memory 14, it is determined whether or not the character code (character code of the external character) is stored in the similar character table 2A, and it is stored. If so, the character code of the similar character is supplied to the recording unit 13. If the supplied character code of the external character is not stored in the similar character table 2A, the processes of steps S4 to S8 described above are executed, and the finally obtained character code is supplied to the recording unit 13. The recording unit 13 stores the supplied character code on, for example, a magnetic tape, a floppy desk, or the like.

When the obtained document stored in the floppy desk or the like is printed by an external printer or displayed on a display device, the external character in the document is replaced with a similar character or a kana character, so that it is easy to read. The document is printed or displayed.

[0044]

As described above, according to the present invention, the contents described in a document can be easily determined, as compared with the case where an external character is replaced with a special symbol and output. Moreover, the number of registered fonts does not increase due to external characters, and the maintenance / renewal of the device is facilitated.
