Further, when the head of each word in the text memory (5) is a Chinese character, the modifier information indicating that it is a Chinese character is added to the head of such a word. (6) is the cursor address part, currently the CRT
(4) The corresponding position in the text memory (5) of the cursor displayed above is stored. (7) is a display control unit, which displays the information stored in the text memory (5) on the CRT (4) and also corresponds to the position information stored in the cursor address unit (6). (4) The upper position is highlighted. Reference numeral (8) is a dictionary in which kanji and kana mixed words are stored corresponding to the reading information. (9)
Is a reading buffer in which reading information is stored. (Ten)
Is a conversion character buffer, and (11) is a conversion unit, which reads the kanji and kana mixed words corresponding to the reading information stored in the reading buffer (9) from the dictionary (8) and the conversion character buffer (10). To store. (17) is a text search unit, which exists after the position of the text memory (5) corresponding to the position information stored in the cursor address unit (6) and is closest to the position. The information having the modification information at the position is searched, and the position of such information in the Texas memory (5) is output. Reference numeral (12) is a kanji reading registration unit in which a word (hereinafter simply referred to as display information) having a kanji character at the beginning in the text memory (5) as shown in FIG. It is stored together with the head position in (5). (13) is the save buffer,
(14) is a head position register and (15) is a Chinese character length register, which has a current Chinese character length area (15a) and an old Chinese character length area (15b). Reference numeral (16) denotes an edit processing unit, which performs edit processing such as insertion and deletion on the document information in the text memory (5).

Next, the operation of such a device will be described based on a specific example.

Now, assuming that the information corresponding to the document displayed on the CRT (4) is stored in the text memory (5) as shown in FIG. 3, the kanji reading registration section (12) is shown in FIG. ), "Kyo", "pass" in the text memory (5),
The beginning position of each word in the reading and text memory (5) is stored corresponding to each word of "birthday". For convenience of explanation, the memory position in the text memory (5) and the display position on the CRT (4) are the same. That is, the positions represented by (1,1) (1,2) ... on the CRT (4) screen are (1,1) (1,) of the text memory (5), respectively.
2) ... is associated with each.

Further, as shown in FIG. 3 (a), the cursor position on the CRT (4) is indicated by a square frame. Therefore, (1,1) is stored as position information in the cursor address portion (6). In addition, the Chinese character “Kyo” in the text memory (4),
The above-mentioned modification information is added to the information indicating "watari" and "birth", respectively.

In such a state, when the re-conversion key is input from the input unit (3), the main control unit (1) exists in the text search unit (17) after the current cursor position and the text closest to the position. The position of the information having the above-mentioned modification information existing in the position in the memory (5) is searched (first step).
At this time, the information at the cursor position (1,1) and at the position (1,1) indicates the Chinese character “Kyo”, and since the modification information is added to such information, the text search is performed. The section (17) outputs the position (1,1).

When such position is output, the main control unit (1) stores the position information in the cursor address unit (6) and then stores it in the Kanji reading registration unit (12) in correspondence with the position information. Read the display information and reading that are present, and read the above reading buffer (9)
In addition, the display information read out and the number of characters constituting the reading are checked and stored in the old kanji length area (15b) and the current kanji length area (15a) of the kanji length register (15) (second step). Specifically, since the position information output from the text search unit (17) is now (1,1), the reading “kyo” is stored in the kanji length register (1
The number of characters "1" and "3" are stored in the old Chinese character area (15b) and the current Chinese character length area (15a) of 5), respectively.

After that, the main control unit (1) uses the text memory (17) to obtain information corresponding to the number of characters stored in the current Kanji area (15a) from the position corresponding to the position information stored in the cursor address unit (6). The contents of the cursor address part (6) are stored in the read start position register (14) while being read and stored in the save buffer (13) (third step). Therefore, the save buffer (13) stores the information corresponding to the three characters "Kyowa Watari", and the head position register (14) stores the position information (1,1).

Next, the main control unit (1) writes the contents of the read buffer (9) into the area of the text memory (5) whose head is the position stored in the head position register (14) and the cursor address unit (6). ) Content is increased by the number of characters stored in the current Kanji length area (15a), and the cursor is moved to CRT (4)
Move to the right on the screen (4th step). Therefore,
As shown in FIG. 4, the contents of the text memory (5) are changed, and the contents of the cursor address portion (6), that is, the cursor position is also changed to (1,4).

Then, when the conversion key is input from the input unit (3), the main control unit (1) causes the conversion unit (11) to read the reading buffer (9).
The kana-kana-mixed word corresponding to the reading stored in is read from the dictionary unit (8), and the word is stored in the converted character buffer (10) (fifth step). Specifically, since the reading buffer (9) now stores the reading "Kyo", words such as "Kyo", "Today", "Sutra" are shown in Fig. 5 in the conversion character buffer (10). Stored as shown.

Next, the main control unit (1) writes the contents stored in the save buffer (13) from the position in the text memory (5) indicated by the position information stored in the head position register (14) ( 6 steps). Specifically, since the character string "Kyo wa Wataru" is stored in the save buffer (16) and the position information (1,1) is stored in the head position register (14), the text memory (5 The contents of) are returned to those shown in FIG. 3 (a).

Then, the main control unit (1) reads out the word stored at the head of the conversion character buffer (10), checks the number of constituent characters of such word, and determines the number of characters in the current Kanji length area (of the Kanji length register (15) ( 15a) and the word is written from the position in the text memory (5) indicated by the position information stored in the head position register (14), and then the contents of the cursor address portion (6) are written in the head position register (6). The contents of the current Chinese character length area (15a) are added to the contents of 14) to replace the result (seventh step). Specifically, since the word "Kyo" is stored at the beginning of the conversion character buffer (10), the contents in the text memory (5) are as shown in FIG. 6, and the current Kanji length area ( Since the content of 15a) is "1" and the content of the head position register (14) is (1,1), the content of the cursor address part (6) is (1,2), and therefore, on the CRT (4). The cursor is displayed at the (1,2) position of.

After that, when the conversion key is continuously input from the input unit (3), the same processing as in the sixth and seventh steps is repeated, but the previous conversion key is input from the conversion character buffer (10). The word stored at the position next to the word that has been read at some time is read (8th step). Therefore, the word "today" stored at the next position of the word "Kyo" from the conversion character buffer (10) is written to the position starting from (1,1) in the text memory (5), and the current The contents of the Chinese character length area (15a) and the cursor address portion (6) are "2" and (1,3), respectively. Therefore, the display on the CRT (4) is as shown in FIG.

After that, every time the conversion key is continuously input, the
The steps are repeated so that the words in the conversion character buffer (10) are sequentially written into the text memory (5) and the CRT
(4) will be displayed above.

After the completion of the eighth step, when a key other than the conversion key is input from the input section (3), the process is performed so that the word selected in the eighth step is confirmed. That is, the main control unit (1) first determines the current kanji length area (15a) and the old kanji length area (15a).
When comparing the contents with b) and judging that the contents of the current kanji length area (15a) are large, the edit processing part (16) is instructed to perform the inserting operation described later, and the old kanji length area ( 15b)
If it is determined that the content of the item is large, the editing processing section (16) is instructed to perform the deleting operation described later, and the operation ends (step 9).

i) Inserting operation First, the edit processing unit (16) writes the contents of the save buffer (13) into the text memory (5) in the same manner as in the sixth step, and thereafter, indicates the contents of the start position register (14). The information corresponding to each character after the position in the text memory (5) is shifted to the right by the difference between the contents of the current Kanji length area (15a) and the contents of the old Kanji length area (15b),
Next, in the above eighth step, the conversion character buffer (1
The word read from 0) is added with the modification information to the head character, and the word is written again to the position in the text memory (5) whose head is the position stored in the head position register (14).

Further, the processing section (16) has a Kanji reading registration section (12) in which the same content as the content of the head position register (14) is stored.
The position information stored in the head position register (14) among the position information stored in the position area of the other Kanji reading registration unit (12) while writing the word in the display information area corresponding to the position area of The larger one is increased by the above difference.

Specifically, assuming that the CRT (4) is displayed as shown in FIG. 7 after the end of the eighth step, the insertion operation causes (1,1 in the text memory (5) to be displayed. ) ~
Since the information corresponding to the document "Today is my birthday" is stored in the (1,12) position, the CRT
(5) The display above is as shown in FIG. 8 (a). The contents of the Kanji reading registration section (12) are changed as shown in FIG. 8 (b).

ii) Deletion operation First, the edit processing unit (16) writes the contents of the save buffer (13) into the text memory (5) in the same manner as in the sixth step, and thereafter, the contents of the start position register (14) indicate it. From the position in the text memory (5) to be deleted, the information corresponding to the characters corresponding to only the difference between the contents of the old kanji length area (15b) and the contents of the current kanji length area (15a) is deleted, and then in the above eighth step. The word read from the conversion character buffer (10) is added to the leading character with modification information, and the word is written again to the position in the text memory (5) whose head is the position stored in the head position register (14). . Further, the processing section (16) writes the word in the display information area corresponding to the position area of the Kanji reading registration section (12) in which the same content as the content of the head position register (14) is stored and Of the position information stored in the position area of the Chinese character reading registration unit (12), which is larger than the position information stored in the head position register (14), the difference is reduced by the above difference.

Specifically, in the state as shown in FIG. 8 (a), the processes of the first to eighth steps are now performed, and the word "I" for the reading "I" is shown in FIG. 9 (a). If it is stored in the text memory (5) so as to be displayed on the CRT (4) as described above, at this time, the start position register (14), the current kanji length area (15a), the old kanji length area (15)
The contents of b) are (1,4), "1", and "2", respectively.
The deletion operation is executed, and as a result, the information corresponding to the document "Today is my birthday" is stored in the positions (1,1) to (1,11) in the text memory (5). Becomes Therefore, the display on the CRT (4) is shown in Fig. 9 (a).
In addition, the contents of the Kanji reading registration section (12) are changed as shown in FIG. 9 (b).

In the present embodiment, when a key other than the conversion key is input after the processing of the eighth step is finished, the operation is ended after the processing of the ninth step. When a specific key such as a re-conversion key or a cursor movement key is input, the process may be returned to the first step after the ninth step.

(G) Effect of the Invention According to the present invention, the re-converted word is searched by searching the text memory, so that the process is performed quickly. Furthermore, the reconverted word can be searched according to the cursor position.
