Abstract

PROBLEM TO BE SOLVED: To make it possible to simultaneously execute character conversion for plural characters included in a cursor range without individually specifying an en character e.g. by an en cursor and converting the specified character when the character preparing device has a character converion function for converting a HIRAGANA (cursive form of Japanese syllabary) character into its corresponding KATAKANA (square form of Japanese syllabary) character at the time of preparing document data. SOLUTION: When character data on a document area specified by an em cursor are an alphabetical character string 'AB' consisting of en uppercase letters at the time of depressing an uppercase letter/lowercase letter conversion key, the left side character 'A' and the right side character 'B' included in the cursor range are successively read out based on cursor size and a cursor position and converted into respectively corresponding lowercase letters 'ab'. Thus two en characters included in the cursor range of em size can be simultaneously converted.

It is stored in advance.

The JIS code table 14 is composed of a ROM. In the JIS code table 14, individual character code data corresponding to all JIS standard characters and symbols that can be input by operating the keyboard 12 are tabulated. And stored in advance. In this case, uppercase / lowercase characters of English characters and different character types of the same content, and character codes of Japanese characters Hiragana / Katakana and alphanumeric characters / Kanji numerals of numbers are all stored as table data associated with each other. You.

The CG-ROM 15 stores in advance display and print font pattern data corresponding to all characters and symbols that can be input by operating the keyboard 12 in association with the respective character and symbol codes. You.

The document buffer 16 is composed of a RAM. In the document buffer 16, document data inputted by the keyboard 12 is written and stored as an array of character codes for each character. The storage position is associated with a row and column position of a document format set in advance. In this case, the character code of the double-byte character is
The half-width input character code is stored in the character modification table 17 and stored in the memory area corresponding to the input line and column position of the document buffer 16. Stores address data indicating the storage destination of the character modification table 17.

In other words, if the key-input character is a modifier character, the memory area corresponding to the input line digit position of the document buffer 16 stores the character code of the modifier character itself in the memory area. The storage destination address is stored.

In the cursor position register 18, position data indicating the designated position of the cursor on the document data displayed on the display 21 by m rows and n digits is set. In the cursor size register 19, “0” is set for a full-size cursor in the full-width mode, and “1” is set for a half-size cursor in the half-width mode.

The work RAM 20 temporarily stores various data input / output to / from the CPU 11 in accordance with various processes of the word processor as needed. FIG. 2 is a diagram showing a size data storage state in the cursor size register 19 of the word processor.

In the case of a full-size cursor in the full-size mode, full-size data "0" is set.
In the case of a half size cursor in the half size mode, half size data "1" is set.

FIG. 3 is a diagram showing a storage state of position data in the cursor position register 18 of the word processor. If the full-width cursor points to the m-line / n-th digit in the document area, or if the half-width cursor points to the left of the m-line / n-th digit in the document area, the digit side Is set to “m rows and 0n digits” in which the first bit of the “m” is “0”.
When the right side of the n-th digit is designated, position data of “m rows × 1n digits” in which the leading bit of the digit side is “1” is set.

That is, in the case of a full-width cursor whose size data set in the cursor size register 19 is “0”, the cursor is set to the position data “m rows and 0n digits” set in the cursor position register 18. In the case of a half-size cursor whose size data is “1”, it is determined that the cursor is located at the m-th row and the n-th digit, and the cursor is located at the left side of the m-th row and the n-th digit with the position data “m row and the 0n digit” , And the position data “m rows · 1n
It is determined that the cursor is located on the right side of the m-th row and the n-th digit in "digit".

FIG. 4 is a diagram showing the data storage state of the m-th row and n-th column in the document buffer 16 of the word processor. When a character is input in the full-width mode at the m-th line and n-th digit in the document area, the character code corresponding to the input full-width character is stored as it is, and the half-width character is stored at the m-th and n-th digit in the document area. When a character is input in the mode, the memory address N of the character modification table 17 indicating the storage destination of the character code corresponding to the input half-width character is stored.

FIG. 5 is a diagram showing a data storage state of address N in the character modification table 17 of the word processor. That is, when two half-width characters are input in the m-th row and n-th digit of the document area in the half-width mode, the memory of the character modification table 17 indicated as the data in the m-th row and n-th digit of the document buffer 16 For the address N, the left half-width character code and the right half-width character code of the corresponding half-width character are stored.

Next, the operation of the word processor having the above configuration will be described. FIG. 6 is a flowchart showing the uppercase / lowercase conversion processing of the word processor.

For example, it is determined that the uppercase / lowercase conversion key has been operated with the full-width cursor indicating the full-width English character "A" existing at the m-th line and the n-th digit on the document area displayed on the display 21. Then, based on the size data “0” set in the cursor size register 19 and the position data “m rows and 0n digits” set in the cursor position register 18, the document buffer 1
The character code of the cursor designating character "A" is read from the memory data in the m-th row and n-th digit of step 6 (step S1 → S
2, S3).

Then, it is determined that the character code of the lowercase letter "a" corresponding to the cursor designation character "A" read in step S3 exists in the JIS code table 14, and the character code of the uppercase letter "A" is replaced. The character code of the small letter "a" is converted and stored as the data of the m-th line and the n-th digit of the cursor designated position in the document buffer 16 (steps S4 → S5, S6).

Then, it is determined that the conversion process for one double-byte character corresponding to the double-byte size cursor has been completed, and the series of conversion processes has been completed (step S7 → end).
On the other hand, for example, a half-width English character “A” existing on the left side of the m-th line and the n-th column on the document area displayed on the display 21 is displayed.
Is designated with a half-width cursor, and it is determined that the uppercase / lowercase conversion key has been operated, the size data “1” set in the cursor size register 19,
Based on the position data “m line / 0n digit” set in the cursor position register 18, the memory data “modification table address N” of the m line / n digit of the document buffer 16 and the modification table address N are specified. From the first data at the address N in the character modification table 17, the character code of the left half-width character "A" designated by the cursor is read (steps S1 → S2, S3).

Then, a lowercase letter "a" corresponding to the cursor-specified left half-width character "A" read in step S3.
Is determined to exist in the JIS code table 14, the character code of the lowercase letter "a" is converted instead of the character code of the uppercase letter "A", and is newly added as the first data of the address N in the character modification table 17. It is stored (steps S4 → S5, S6).

Then, it is determined that the conversion process for one half-width character corresponding to the half-width size cursor has been completed, and the series of conversion processes has been completed (step S7 → end).
Also, for example, a half-width English character “right” at the m-th line / n-th column on the document area displayed on the display 21 is displayed.
When it is determined that the uppercase / lowercase conversion key has been operated in a state where “B” is indicated by the half-width cursor, the size data “1” set in the cursor size register 19 is set to “1”.
On the basis of the position data “m row / 1n digit” set in the cursor position register 18, the memory data “modification table address N” of the m row / n digit of the document buffer 16 and the modification table address N are specified. The character code of the right-hand half-width character "B" designated by the cursor is read from the second data at the address N in the character modification table 17 (steps S1 → S2, S3).

Then, a lowercase letter "b" corresponding to the cursor-specified right half-width character "B" read in step S3.
Is determined to exist in the JIS code table 14, the character code of the lowercase letter “b” is converted in place of the character code of the uppercase letter “B”, and newly converted as the second data of the address N in the character modification table 17. It is stored (steps S4 → S5, S6).

Then, it is determined that the conversion process for one half-width character corresponding to the half-width size cursor has been completed, and the series of conversion processes is completed (step S7 → end).
FIG. 7 is a diagram showing a character conversion state of a half-width English character string by a full-width cursor accompanying the case conversion processing of the word processor.

For example, when the half-width uppercase English character string “AB” existing at the m-th line and the n-th column on the document area displayed on the display 21 is designated by a full-width cursor,
When it is determined that the lowercase conversion key has been operated, the document buffer is set based on the size data “0” set in the cursor size register 19 and the position data “m rows and 0n digits” set in the cursor position register 18. 1
6, the half-width character "AB" designated by the full-width cursor is obtained from the memory data "modification table address N" in the m-th row and n-th digit and the first data at the address N of the character modification table 17 designated by the modification table address N Is read out (step S1 →
S2, S3).

Then, it is determined that the character code of the lowercase letter “a” corresponding to the cursor-specified half-width left character “A” read in step S3 exists in the JIS code table 14, and the character code of the uppercase letter “A” is determined. The character code of the lowercase letter "a" is converted and is newly stored as the first data of the address N in the character modification table 17 (steps S4 → S5, S6).

In this case, it is determined that the conversion process for two right and left half-width characters corresponding to the full-size cursor has not been completed, and the process returns to the process from step S3 onward (step S7 → S3).

Then, next, m lines in the document buffer 16
From the memory data “modification table address N” of the n-th digit and the second data at the address N of the character modification table 17 specified by the decoration table address N, the right side of the half-width character “AB” designated by the full-width cursor The character code of the character "B" is read (step S3).

Then, it is determined that the character code of the lowercase letter “b” corresponding to the cursor-specified half-width right character “B” read in step S3 exists in the JIS code table 14, and the character code of the uppercase letter “B” is determined. The character code of the lowercase letter "b" is converted and is newly stored as the second data of the address N in the character modification table 17 (steps S4 → S5, S6).

Then, it is determined that the conversion processing for the two right and left half-width characters corresponding to the full-size cursor has been completed, and the series of conversion processing is completed (step S7 →
End).

As a result, the English character string "AB" of a single-byte uppercase letter included in the designated range of the double-byte cursor is converted into the corresponding English-character string "ab" of a single-byte lowercase character. Note that, even when the half-width lowercase English character string “ab” existing in the document area is designated with a full-width cursor and the uppercase / lowercase conversion key is operated, the same processing as described above is performed to specify the half-width lowercase English text designated by the cursor. The character string "ab" is converted to an English character string "AB" in single-byte capital letters.

FIG. 8 is a diagram showing a character conversion state of a half-width English character string (mixed upper- and lower-case letters) by a full-width cursor accompanying the case conversion processing of the word processor. For example, the uppercase / lowercase conversion key is operated in a state in which the half-width uppercase and lowercase English character string “Ab” existing at the m-th line and the n-th column in the document area displayed on the display 21 is indicated by the full-width cursor. If it is determined that the cursor data is "0" in the document buffer 16 based on the size data "0" set in the cursor size register 19 and the position data "m line 0n digit" set in the cursor position register 18. From the memory data “modification table address N” of the digit and the first data at the address N of the character modification table 17 designated by the modification table address N,
The character code of the left character "A" of the half-width character "Ab" designated by the full-width cursor is read (step S1).
→ S2, S3).

Then, it is determined that the character code of the lowercase letter "a" corresponding to the cursor designation half-width left character "A" read in step S3 exists in the JIS code table 14, and the character code of the uppercase letter "A" is determined. The character code of the lowercase letter "a" is converted and is newly stored as the first data of the address N in the character modification table 17 (steps S4 → S5, S6).

In this case, it is determined that the conversion process for the left and right half-width characters corresponding to the full-width size cursor has not been completed, and the process returns to step S3 and subsequent steps again (step S7 → S3).

Then, next, m lines in the document buffer 16
From the memory data “modification table address N” of the n-th digit and the second data at the address N of the character modification table 17 specified by the decoration table address N, the right side of the half-width character “AB” designated by the full-width cursor The character code of the character "b" is read (step S3).

Then, it is determined that the character code of the capital letter “B” corresponding to the cursor-specified right-byte character “b” read in step S3 exists in the JIS code table 14, and the character code of the small letter “b” is determined. The character code of the capital letter "B" is converted and is newly stored as the second data of the address N in the character modification table 17 (steps S4 → S5, S6).

Then, it is determined that the conversion process for the two right and left half-width characters corresponding to the full-size cursor has been completed, and the series of conversion processes has been completed (step S7 →
End).

As a result, the English character string "Ab" in which the single-byte uppercase and lowercase characters are mixed within the designated range of the full-width cursor is
Both are converted to the corresponding English character string "aB" in lower case and upper case.

The same processing as described above is also used to specify the cursor by operating the uppercase / lowercase conversion key by designating the half-width lowercase and uppercase English character string "aB" existing in the document area with the full-width cursor. The half-width lowercase and uppercase mixed English character string “aB” is converted into a single-byte uppercase and lowercase mixed English character string “Ab”.

Therefore, according to the word processor having the above configuration, when the upper / lower case conversion key is operated,
If the character data in the document area indicated by the full-width cursor is a single-byte uppercase English character string "AB", the left character "A" and the right character "B" included in the cursor range are Since it is sequentially read out based on the cursor size and the cursor position and converted into the corresponding lowercase letter “ab”, the document data input in the half-width mode is operated by operating the half-width size cursor in the half-width mode. It is not necessary to specify individual half-width characters and perform character conversion processing, and character conversion processing can be performed at once for each of the two half-width characters included in the full-width size cursor range.

Even when the two half-width characters on the document area designated by the full-width cursor are English character strings "Ab" and "aB" in which both uppercase and lowercase letters are mixed, the cursor range is similarly determined. The left-hand characters "A" and "a" and the right-hand characters "b" and "B" are read out sequentially based on the cursor size and cursor position, and the corresponding uppercase and lowercase English character string "aB" Or "Ab".

In the embodiments described above, when the character string included in the designated range of the full-width cursor is an English character string of two half-width characters, the two English half-width characters are changed between uppercase and lowercase. Although the operation of converting at once has been described, the conversion target character string indicated by the cursor is not limited to uppercase / lowercase conversion of an English character string. For example, a hiragana / katakana conversion of a Japanese character string, an alphanumeric character / kanji number of a numerical character string Even the conversion can be easily realized by the same processing as in the above embodiment.

[0051]

As described above, according to the document creating apparatus of the present invention, a character-size inputting operation is performed for a character string data input in, for example, a half-width mode by a character inputting means. When an arbitrary character string is designated by the operator, based on the designated position of the cursor on the character string data stored in the cursor position storage means and the size of the cursor stored in the cursor size storage means, the specified character string is included in the specified range of the cursor. The two half-width character data are sequentially read out, and the two read-out half-width character data are respectively based on the table data stored in the character table storage means. Is converted to character data of the same type but in a different representation Character conversion process at a time for each of the two half-width characters in is so performed.

Therefore, according to the present invention, it is possible to perform character conversion at once for each of a plurality of characters included in the cursor range without the need to individually specify and convert single-byte characters with a single-byte cursor.
