Abstract

PURPOSE: To efficiently obtain KANJI (Chinese character) which a user desires, in one character conversion/single KANJI conversion/radical conversion functions. CONSTITUTION: When a 'head part conversion' key 11b or a 'final part conversion' key 11c is operated at the time of reading input or after a conversion result is outputted, a control part 12 executes one character conversion through a one character conversion part 13b. When a candidate concerned cannot be obtained in a character string (reading) at the time of input, the control part 12 changes the reading range of the inputted character string through a single KANJI conversion part 13c and executes single KANJI conversion. When a 'radical conversion' key lie is operated after the character string (radical name) is inputted, the control part 12 changes the reading range of the inputted character string through a radical conversion part 13d and executes radical conversion.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character conversion method used in a document preparation device such as a Japanese word processor, and more particularly to a character conversion method used when performing one-character conversion, single-kanji conversion or radical conversion. .

[0002]

2. Description of the Related Art Conventionally, a document creation device such as a Japanese word processor has a kana-kanji conversion function. For example, when reading "kanji", "kanji" is added to the input kana character string. , It is possible to automatically output the corresponding mixed Kanji character string. By using such a kana-kanji conversion function, the user can convert the reading into kana-kanji and create a document while inputting the reading.

By the way, in addition to the kana-kanji conversion function as described above, there are functions called one-character conversion, single-kanji conversion, and radical conversion as functions for supporting document creation.
The one-character conversion function is called so-called telegram conversion, and it is positioned at the beginning or end of the character string obtained as a conversion result of kana-kanji conversion, such as "kanji" for "kanji" or "character" for "kanji". This is a function to obtain the characters to be converted as conversion candidates.

The single-kanji conversion function is a function of inputting a reading in units of one character and obtaining a single kanji corresponding to the reading as a conversion candidate. For example, if you enter the pronunciation "kan" and indicate single-kanji conversion, "dry", "crown",
A single kanji with the reading of "kan" is obtained, such as "cold", "published", "kan".

The radical conversion function is a function of inputting a radical name of a Chinese character to obtain a radical Chinese character corresponding to the radical name as a conversion candidate. For example, if you enter "sanzui" to indicate radical conversion, "juice", "shore", "ren",
Radical kanji with "sanzui" such as "dirty", "sweat", etc. are obtained.

[0006]

As described above, in the conventional document creating apparatus, it is possible to create a document by appropriately using the functions such as one-character conversion, single-kanji conversion, and radical conversion. However, each function has the following problems.

That is, conventionally, in the case of performing the one-character conversion function, first, a kana-kanji conversion of a character string to be converted is performed, and then a character before or after the conversion result is designated. Was required. Therefore, when a character string (reading) is input, a desired kanji cannot be immediately obtained, and there is a problem that operability is very poor.

Further, even in the case of obtaining from the conversion result, since the method of fixing the character before or after the one candidate obtained as the conversion result is adopted, the desired candidate is first designated by the next candidate instruction or the like. It was necessary to display candidates. For this reason, not only an extra key operation is required, but there is a possibility that an incorrect conversion may be performed due to a wrong conversion candidate.

Further, in the single-kanji conversion and radical conversion, only the input character strings have been targeted.
Therefore, if a corresponding conversion candidate cannot be obtained from the input character string, it is necessary to re-input a new character string.

Here, in the single-kanji conversion, usually, a kanji that cannot be obtained by the kana-kanji conversion is obtained by the single-kanji conversion. In such a case, conventionally, after canceling the character string (reading) input at the time of kana-kanji conversion, it was necessary to re-input the character string for single kanji conversion.

In radical conversion, it is necessary to accurately input the registered radical name. For example, "tree",
Kanji characters such as "tag", "book" ... are usually registered under the radical name "ki". If this is entered as "Ken", no conversion will be performed. Therefore, when the radical name is erroneously input, the input character string (radial name) at that time must be canceled and the correct character string must be re-input.

The present invention has been made in view of the above points, and an object thereof is to provide a character conversion method capable of efficiently obtaining a kanji desired by a user with a simple operation in a single character conversion function. .

Further, the present invention provides a character conversion method capable of efficiently obtaining a Kanji desired by a user by utilizing a character string (reading) input at the time of Kana-Kanji conversion in the single-Kanji conversion function. The purpose is to

Further, according to the present invention, in the radical conversion function,
It is an object of the present invention to provide a character conversion method that can efficiently obtain a Chinese character desired by a user by using an input character string (radical name).

[0015]

[Means for Solving the Problems]

(1) In the character conversion method of the present invention, after inputting character string information,
By inputting a specific key for single character conversion, if the specific key indicates head conversion, it is located at the head of each conversion candidate information obtained when the input character string information is converted into Kana-Kanji. When the character information is extracted and the specific key indicates the end conversion, the character information located at the end of each conversion candidate information obtained when the input character string information is converted into kana-kanji is extracted. The character information thus extracted is output as a single character conversion result.

Further, according to the character conversion method of the present invention, by inputting a specific key for converting one character in a state where one conversion candidate information of the kana-kanji conversion result for the input character string information is output, the specific key Indicates the beginning conversion, the character information located at the beginning of each conversion candidate information existing as the above Kana-Kanji conversion result is extracted, and when the specific key indicates the ending conversion, the Kana-Kanji conversion is performed. Characteristic information located at the end of each conversion candidate information existing as a conversion result is extracted, and each extracted character information is output as a one-character conversion result.

Further, according to the character conversion method of the present invention, by inputting a specific key for converting one character while the candidate list information of the kana-kanji conversion result for the input character string information is output, the specific key is changed. When indicating the head conversion, the character information located at the head of each conversion candidate information existing in the candidate list information is extracted, and when the specific key indicates the tail conversion, Characteristic information located at the end of each conversion candidate information existing in the candidate list information is extracted, and each extracted character information is output as a one-character conversion result.

(2) In the character conversion method of the present invention, when the corresponding conversion candidate information is not obtained when the input character string information is converted into kana-kanji, the reading range of the input character string information is set to 1 It is characterized in that each character is narrowed, the corresponding single kanji information is searched for each reading range, and the searched single kanji information is output as a single kanji conversion result.

(3) In the character conversion method of the present invention, when the character string information input as a radical name is radically converted, the reading range of the input character string information is narrowed by one character and each reading range is reduced. It is characterized in that the corresponding radical kanji information is retrieved for each case and the retrieved radical kanji information is output as a radical conversion result.

[0020]

[Action]

(1) According to the character conversion method of the present invention, one character conversion can be executed at the time of reading input. Further, after outputting the kana-kanji conversion result, one-character conversion can be executed even in the state where one candidate of the conversion result is displayed or in the state where the candidate list of the conversion result is displayed.

(2) According to the character conversion method of the present invention, when the corresponding candidate cannot be obtained from the character string (reading) at the time of input, the reading range of the input character string at that time is changed to obtain a single Kanji character. The conversion can be performed automatically. (3) According to the character conversion method of the present invention, radical conversion can be continuously executed while changing the reading range of the input character string.

[0022]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a document creation apparatus using the character conversion method of the present invention. This device includes an input unit 11, a control unit 12, a conversion unit 13, a storage unit 14, and an output unit 1.
Have 5.

The input unit 11 is composed of, for example, a keyboard, and is used for inputting and instructing data. This input unit 11 has a "character" for inputting character data.
In addition to the keys and "number" keys, the "cursor" key for moving the cursor, the "next candidate" key for instructing the display of the next candidate, the "confirm" key for confirming the selection of candidates, etc. Here, a "kana-kanji conversion" key 11a, a "start part conversion" key 11b, a "last part conversion" key 11c,
It has function keys such as a "single-kanji conversion" key 11d and a "radical conversion" key 11e.

The "kana-kanji conversion" key 11a is a function key for instructing a kana-kanji conversion function.
The kana-kanji conversion function is a function of inputting a reading and obtaining a kanji-mixed character string corresponding to the reading as a conversion candidate.

The "start part conversion" key 11b and the "last part conversion" key 11c are function keys for instructing the one-character conversion function. The one-character conversion function is a function of obtaining a character positioned at the beginning or end of a character string obtained as a conversion result of kana-kanji conversion as a conversion candidate. Here, the "leading part conversion" key 11b is used to obtain the leading character, and the "last part conversion" key 11c is used to obtain the trailing part character.

The "single-kanji conversion" key 11d is a function key for instructing a single-kanji character function. The single-kanji conversion function is a function of inputting a reading in units of one character and obtaining a single kanji corresponding to the reading as a conversion candidate.

The "radical conversion" key 11e is a function key for instructing a radical conversion function. The radical conversion function is a function of inputting a radical name of a Chinese character to obtain a radical Chinese character corresponding to the radical name as a conversion candidate.

The control unit 12 is composed of, for example, a microprocessor and controls the entire apparatus. Here, the conversion unit 13 performs a document creation process. Converter 13
Is a program stored in a ROM, for example, which performs character conversion processing under the control of the control unit 12.
Here, the kana-kanji conversion unit 13a and the one-character conversion unit 13
b, a single Kanji conversion unit 13c, and a radical conversion unit 13d.

The kana-kanji conversion unit 13a performs kana-kanji conversion processing in response to the input of the "kana-kanji conversion" key 11a. The one-character conversion unit 13b uses the "start conversion" key 11b.
Alternatively, one character conversion processing (head conversion processing / last conversion processing) is performed in response to the input of the "last conversion" key 11c.
The single-kanji conversion unit 13c performs single-kanji conversion processing in response to the input of the "single-kanji conversion" key 11d. Radical converter 13d
Performs radical conversion processing in response to the input of the "radical conversion" key 11e.

The storage unit 14 is composed of, for example, a RAM and stores various kinds of information necessary for creating a document, and has a kana-kanji conversion dictionary 14a and a single kanji conversion dictionary 14b here.

The kana-kanji conversion dictionary 14a is a dictionary used for kana-kanji conversion, and consists of readings (headings) and conversion words corresponding thereto. For example, for the reading "Kanji", conversion words such as "feeling", "kanji", "secretary", "auditor", "Kanji" ... Are registered.

The Kana-Kanji conversion dictionary 14a is composed of a standard dictionary and a user dictionary (new word dictionary), and both of these dictionaries are referred to when converting Kana-Kanji. The standard dictionary is
It is a standard dictionary created in advance. The user dictionary is a dictionary created by the new word registration function during document creation.

The single-kanji conversion dictionary 14b is a dictionary used for single-kanji conversion or radical conversion, and is composed of a reading (heading) for each character and a corresponding conversion word (single-character kanji). For example, for the reading "kan",
The conversion words such as "dry", "crown", "cold", "published", "kan" ... are registered.

The output unit 15 is, for example, an LCD (Liquid Cry).
It is composed of a display device such as a stal display) or a CRT (Cathode Ray Tube), and is for displaying input data, conversion results, and the like.

Next, the operation of the embodiment will be described. Here, as the character conversion processing, (a) single character conversion processing,
Each operation of (b) single kanji conversion processing and (c) radical conversion processing will be described.

(A) Single-character conversion processing The single-character conversion function is provided at the beginning or end of a character string obtained as a conversion result of kana-kanji conversion, such as "kanji" for "kanji" or "character" for "kanji". This is a function to obtain the located character as a conversion candidate.

Here, in this embodiment, one character is input at the time of reading input or after the output of the kana-kanji conversion result (the state in which one candidate of the conversion result is displayed / the state in which the candidate list of the conversion result is displayed). The conversion can be performed.

First, the one-character conversion process at the time of reading input will be described. FIG. 2 is a flowchart showing the operation of the one-character conversion process at the time of reading input in the embodiment. First, the character string (reading) to be converted through the input unit 11
After inputting "," the "conversion at the beginning" key 11b or the "conversion at the end" key 11c is inputted (step A11). This input information is given to the kana-kanji conversion unit 13a of the conversion unit 13 through the control unit 12.

The kana-kanji conversion unit 13a converts the input character string into kana-kanji by referring to the kana-kanji conversion dictionary 14a (standard dictionary and user dictionary) (step A12). At this time, the control unit 12 deciphers whether the function key is the "leading part conversion" key 11b or the "last part conversion" key 11c, and the result is one character together with the kana-kanji conversion result obtained by the kana-kanji conversion part 13a. Send to the conversion unit 13b.

If the "head conversion" key 11b is input as a function key during reading input, the one-character conversion unit 13b determines that the head conversion has been instructed (Yes in step A13), and kana-kanji conversion is performed. From the resulting character string (one of the conversion candidates), the character located at the beginning is extracted (step A14). The control unit 12 receives this extracted character as a one-character conversion result from the one-character conversion unit 13b and displays it on the output unit 15 (step A15).

The character displayed as the conversion result at this time is extracted from one candidate character string of a plurality of conversion candidates obtained by the kana-kanji conversion. If this character is not the desired Kanji character, the "next candidate" key provided in the input unit 11 is operated to display the next candidate. If the character is a desired Chinese character, the "confirm" key provided in the input unit 11 is operated to confirm the candidate.

When the display of the next candidate is instructed by operating the "next candidate" key (Yes in step A16), the control unit 1
2. The character extraction processing similar to the above is performed using the conversion candidate next to the conversion result of the kana-kanji character (step A14).

When there is a confirmation instruction by operating the "confirmation" key (Yes in step A17), the control unit 12 confirms the currently displayed candidate as the one-character conversion result. At this time, the control unit 12 performs a new word registration process as shown in FIG. 3 (step A18).

FIG. 3 is a flow chart showing the operation of the new word registration process at step A18. That is, the control unit 12 first refers to the Kana-Kanji conversion dictionary 14a (standard dictionary and user dictionary) to check whether the determined candidate character is an unknown word (step B11). An unknown word is a word that does not exist in the dictionary. As a result, if it is an unknown word (Yes in step B12), the control unit 12 registers the candidate character in the kana-kanji conversion dictionary 14a (user dictionary) with the reading input at that time (step B13).

On the other hand, in step A13 of FIG. 2, when the "last part conversion" key 11c is input as a function key during reading input, the one-character conversion part 13b judges that the last part conversion is instructed, and the kana-kanji The character located at the end of the character string (one of the conversion candidates) obtained as the conversion result is extracted (step A1).
9). The control unit 12 outputs the extracted character as a one-character conversion result to the output unit 15 and displays it on the display (step A20).

Thereafter, similarly to the above, the next candidate is displayed in response to the display instruction of the next candidate by operating the "next candidate" key (step A21), and in response to the confirmation instruction by operating the "set" key. Then, the candidate is confirmed (step A22), and new word registration processing is performed (step A18).

FIG. 4 shows a specific example. For example, if "Kanji" is input as the character string to be converted and then the "starting part conversion" key 11b is input (see FIG. 4 (a)), kana-kanji conversion results in "feeling", "kanji",
Conversion results such as “secretary”, “auditor”, “Kanji” ... are obtained (see FIG. 4B).

Here, first, for the character string "feeling" that is the first candidate, the first character "feeling" is extracted and displayed as a one-character conversion result. When this is confirmed by the operation of the "confirm" key, if it is an unknown word, it is registered as a new word in the kana-kanji conversion dictionary 14a (user dictionary) with the reading "kan" (see FIG. 4 (c)). When the "Next Candidate" key is operated, "Kan" is extracted and displayed from the next candidate, "Kanji." Similarly, candidates such as "Stem", "Supervisor", "Kan" ... Are displayed in order.

The same applies when the "last part conversion" key 11c is pressed. In this case, the character located at the end of the candidate character string is extracted and displayed as the single character conversion result.

In this way, the one-character conversion result can be easily obtained by simply inputting the conversion key at the same time as the reading input. Therefore, it is possible to improve the operability by eliminating the troublesome operation of the related art.

Next, the process for executing the one-character conversion after the output of the kana-kanji conversion result (the state where one candidate of the conversion result is displayed / the state where the candidate list of the conversion result is displayed) is described.

FIG. 5 is a flow chart showing the operation of the one-character conversion process after outputting the kana-kanji conversion result in the embodiment. When the Kana-Kanji conversion result for the input character string (reading) is obtained, if one-character conversion is instructed through the input unit 11 (step C11), the control unit 12 determines whether the instruction is the beginning conversion or the end conversion. And the one-character conversion unit 13b of the conversion unit 13 is activated (step C
12).

Here, if the leading portion conversion instruction is made by operating the "leading portion conversion" key 11b (Yes in step C12), the one-character converting portion 13b extracts the preceding one character of each conversion candidate group (step C13). ). If the last part conversion instruction is made by operating the "last part conversion" key 11c (No in step C12), the one-character conversion part 13
b extracts one character after each of the conversion candidate groups (step C14).

Various information generated during processing, such as a conversion candidate group and extracted characters, is stored in a buffer area (not shown) provided in the storage unit 14. Step C above
When the corresponding character is extracted at 13 or C14, the one-character conversion unit 13b performs a process of merging the same character among the candidate characters (step C15).

Explaining in detail with reference to FIG. 7, for example, when a candidate group for kana-kanji conversion as shown in FIG. 7 (a) is obtained, the fifth "Kanji" and the sixth "Kanji" , And the 8th "Kanji" have the same first character. Therefore, when the head part conversion is instructed, as the conversion result, as shown in FIG.
Can be summarized only.

Similarly, in FIG. 7A, the first and the ninth
One character after the third, fourth, fifth, and seventh candidates is the same character. Therefore, when the last part conversion is instructed, the same characters as above (“ji”, “thing”, “ji”)
Are summarized as shown in FIG.

When each candidate character is created in step C15, the control unit 12 receives each candidate character from the one-character conversion unit 13b as a one-character conversion result and displays the candidate list on the output unit 15. (Step C19),
At this time, the top candidate is set as the current candidate (step C20). In the above example, the “feel” of FIG. 7B or the “ji” of FIG. 7C corresponds to that.

On the other hand, if the one-character conversion instruction in step C11 is displaying the candidate list (step C1
6), the control unit 12 sets the current candidate for the one-character conversion in association with the character extracted from the current candidate when instructing the one-character conversion (step C).
17).

More specifically, referring to FIG. 8, when a candidate group for kana-kanji conversion as shown in FIG. 7A is obtained, the sixth "Kanji" is selected from the candidate list. Then, when the head portion conversion is instructed, a one-character conversion result as shown in FIG. 7B is obtained. At this time, the current candidate becomes the fifth “gentle”.

Similarly, when a candidate group for kana-kanji conversion as shown in FIG. 7C is obtained, if the fourth "auditor" is selected from the candidate list and conversion of the last part is instructed, A one-character conversion result as shown in 7 (d) is obtained. At this time, the current candidate becomes the third “thing”.

In this way, after outputting the kana-kanji conversion result,
The single character conversion can be executed in the state where one candidate of the conversion result is displayed or in the state where the candidate list of the conversion result is displayed. In this case, in the conventional method, since only one candidate obtained as a conversion result had to determine one character before or after that, for example, in order to obtain "Kanji" of "Kanji", kana-kanji It was necessary to obtain a conversion candidate called "Kanji" by conversion using the next candidate instruction, etc., but with this method, one character conversion can be performed to obtain the desired Kanji without this troublesome operation. You can

Next, the cancellation process after the conversion of one character will be described. FIG. 6 is a flow chart showing the operation of the cancellation processing after the conversion of one character in the embodiment. With the result of single character conversion at the beginning or at the end displayed,
When the cancellation of the conversion is instructed by the operation of the "cancel" key provided in the input unit 11 (step D11), the control unit 12 restores the reading for the candidate before the one-character conversion from the internal data (step D12). , The reading character string is displayed on the output unit 15 (step D13).

As described above, after conversion of one character, the reading before conversion can be restored as necessary. That is, in the example of FIG. 7 or 8, if the user cancels the conversion by operating the “cancel” key, the reading “Kanji” is displayed. Therefore, when the desired kanji cannot be obtained, it is possible to confirm the reading at that time and re-input.

(B) Single Kanji Character Conversion Process The single Kanji character conversion function is a function of inputting a reading in units of one character and obtaining a single Kanji character corresponding to the reading as a conversion candidate. For example, if you enter the pronunciation "kan" and indicate single-kanji conversion, "dry", "crown", "cold",
Single kanji with the reading of "kan" can be obtained, such as "published", "kan" ....

Here, in this embodiment, when a corresponding candidate cannot be obtained by kana-kanji conversion, a single kanji conversion is automatically performed while narrowing the reading range by one character. FIG. 9 is a flow chart showing the operation of the single-kanji conversion processing in the embodiment. First, after inputting a character string (reading) to be converted through the input unit 11, a kana-kanji conversion is instructed by operating the "kana-kanji conversion" key 11a (step E11). This input information is given to the kana-kanji conversion unit 13a of the conversion unit 13 through the control unit 12.

The kana-kanji conversion unit 13a refers to the kana-kanji conversion dictionary 14a (standard dictionary and user dictionary) to perform kana-kanji conversion of the input character string (step E13). If it cannot be searched for (No in step E12), the input character string at that time is passed to the single-kanji conversion unit 13c.

As a result, the single-kanji conversion unit 13c narrows the reading range by one character from the entire input character string,
For each reading range, the single-kanji conversion dictionary 14b is referenced to search for single-kanji candidates (steps E14 to E16).

As a result, when there is a corresponding single-kanji candidate (Yes in step E18), the control section 12 receives the single-kanji candidate as a single-kanji conversion result from the single-kanji conversion section 13c and inputs the candidate list. The character string is read and displayed on the output unit 15 (step E19). At this time, the control unit 12 sets the cursor to the head candidate of the candidate group and displays the reading range corresponding to the candidate (current candidate) in a shaded manner (step E20).

In this way, when the list of the conversion results is displayed, for example, by operating the "cursor" key, the cursor is moved to another candidate (step E).
22), the control unit 12 changes the hatching of the reading range according to the current candidate (step E23). When the reading range is switched by operating the "reading range switching" key (step E24), the control unit 12 sets the cursor at the head of the candidate group corresponding to the reading range (step E25).

On the other hand, when the candidate is confirmed by operating the "confirm" key while the cursor is set to the desired candidate (Yes in step E21), the control unit 12 performs the new word registration process as shown in FIG. Perform (step E26).

FIG. 10 is a flow chart showing the operation of the new word registration process in step E26. That is, the control unit 12 first refers to the kana-kanji conversion dictionary 14a (standard dictionary and user dictionary) to check whether the confirmed candidate character (single kanji) is an unknown word (step F11). An unknown word is a word that does not exist in the dictionary. As a result, if it is an unknown word (Yes in step F12)
s), the control unit 12 registers the candidate character (single kanji) in the kana-kanji conversion dictionary 14a (user dictionary) with the reading input at that time (step F13).

FIG. 11 shows a concrete example. For example, it is assumed that "Kina" is input as a character string to be converted and an instruction for kana-kanji conversion is given (see FIG. 11A). If there is no heading for this input character string (reading) in the kana-kanji conversion dictionary 14a, the kana-kanji conversion is automatically switched to single kanji conversion, and the reading range of "Kina" is narrowed by one character, and a single reading is made for each reading range. Single-kanji candidates are searched from the kanji conversion dictionary 14b.

In this case, there is no corresponding single Kanji candidate in reading "Kira". By reading "kita", "plucking",
Single-kanji candidates such as “enemy”, “flute”, “enemy”, “drop”, and “appropriate” are obtained.
Single Kanji candidates such as "hand" and "弖" are obtained (Fig. 11).
(B)). These candidates are arranged and displayed in a list in descending order of reading range (see FIG. 11C).

Here, on the list screen, first, a cursor (indicated by an underline in the figure) is set to "pick" located at the beginning of the candidate group. Further, with respect to the reading character string “Kina” displayed together with each candidate, the portion “Kai” which is the reading range for “Pick” is shaded (FIG. 11).
(See (d)).

In this state, when the cursor is moved to the "hand" by operating the "cursor" key, the display of the reading range is also changed accordingly (see FIG. 11 (e)). Further, when the "fix" key is fixed by operating the "fix" key, if it is an unknown word, the new word "pick" is registered in the Kana-Kanji conversion dictionary 14a (user dictionary) with the reading "Kite" (( See FIG. 11 (f)).

In the state of FIG. 11E, when the reading range is switched from "incoming" to "incoming" by operating the "reading range switching" key, the cursor is placed at the head of the candidate group corresponding to the reading range. Is set (see FIG. 11 (g)).

As described above, when the corresponding candidate cannot be obtained from the character string (reading) at the time of input, the reading range of the input character string at that time is changed to automatically perform single-kanji conversion. , The desired kanji can be obtained by using the character string at the time of input, without requiring the operation of the "single kanji conversion" key 11d.

(C) Radical conversion processing The radical conversion function is performed by inputting the radical name of Kanji.
It is a function to obtain radical Kanji corresponding to the radical name as a conversion candidate. For example, if you enter "sanzui" and indicate radical conversion, "juice", "shore", "ren", "dirt", "sweat" ...
Thus, radical kanji with "sanzui" can be obtained.

Here, the embodiment is characterized in that radical conversion is performed while narrowing the reading range of the character string input as the radical name one character at a time. FIG. 12 is a flowchart showing the operation of radical conversion processing in the embodiment. First, after inputting a character string (radical name) to be converted through the input unit 11, radical conversion is instructed by operating the "radial conversion" key 11e (step G11). This input information is sent to the radical conversion unit 13d of the conversion unit 13 through the control unit 12.
Given to.

The radical conversion unit 13d narrows the reading range by one character from the entire input character string, and searches for a radical Kanji candidate by referring to the single Kanji conversion dictionary 14b for each reading range. (Steps G12 to G15). It should be noted that it is possible not to perform subsequent searches when the search is completed.

As a result, when there is a corresponding single Chinese character candidate (Yes in step G16), the control unit 12 receives the radical Chinese character candidate from the radical converting unit 13d as the radical conversion result, and the candidate list is displayed. The input character string is read and displayed on the output unit 15 (step G17). At this time, the control unit 12 sets the cursor to the first candidate of the candidate group and
The reading range corresponding to the candidate (current candidate) is shaded and displayed (step G18).

In this manner, when the conversion result list is displayed, the cursor is moved to another candidate by operating the "cursor" key, for example (step G
20), the control unit 12 changes the hatching of the reading range according to the current candidate (step G21). When the reading range is switched by operating the "reading range switching" key (step G22), the control unit 12 sets the cursor at the head of the candidate group corresponding to the reading range (step G23).

On the other hand, when the candidate is confirmed by operating the "confirm" key with the cursor being set to the desired candidate (Yes in step G19), the control unit 12 performs a new word registration process as shown in FIG. Perform (step G24).

FIG. 13 is a flow chart showing the operation of the new word registration process in step G24. That is, the control unit 12 first searches for the reading of the radical Chinese character (step H). Next, the control unit 12 uses the kana-kanji conversion dictionary 14
By referring to a (standard dictionary and user dictionary), it is checked whether or not the determined candidate character (radical kanji) is an unknown word (step H12). An unknown word is a word that does not exist in the dictionary. As a result, if it is an unknown word (Yes in step H13), the control unit 12 registers the candidate character (single kanji) in the kana-kanji conversion dictionary 14a (user dictionary) obtained by the reading obtained in step H11 (step H1).
4).

FIG. 14 shows a concrete example. For example, it is assumed that radical conversion is instructed by inputting "kihen" as the radical name character string (see FIG. 14A). By this instruction, the reading range of "kihen" is narrowed by one character, and radical kanji candidates are searched from the single kanji conversion dictionary 14b for each reading range.

In this case, there is no corresponding radical kanji candidate for the radical name of "kihen". In addition, there is no corresponding radical kanji candidate for the radical name of "kihe". With the radical name of "ki",
Radical kanji candidates such as “tree”, “flip”, “book”, “end”, “not yet” are obtained (see FIG. 14B). These candidates are arranged and displayed in a list in descending order of reading range (see FIG. 14C).

Here, on the list screen, first, a cursor (indicated by an underline in the figure) is set to the "tree" located at the head of the candidate group. Further, in the reading character string “Kihen” displayed together with each candidate, the portion of “Ki” which is the reading range for “Tree” is shaded (FIG. 14).
(See (d)).

In this example, since the candidate group is one set, the display of the reading range is not changed or the reading range is not switched by moving the cursor. When inputting the first name, two conversion targets such as “Ninben” and “Ni” are obtained. Therefore, the candidate groups are also two sets such as "I" and "rank" by "Ninben" and "Jin" and "Nii" by "Ni", as in the case of single-kanji conversion (Fig. 11).
(See (e) and (g)), the cursor is moved and the display range of the reading range is changed.

Further, in the state of FIG. 14 (d), when "tree" is confirmed by operating the "confirm" key, if it is an unknown word, the new word "tree" is read as "ki" and kana-kanji conversion. It is registered in the dictionary 14a (user dictionary).

As described above, since radical conversion is continued while changing the reading range of the input character string, a desired Chinese character can be obtained without knowing the radical name that is registered.

In the above embodiment, even when the radical kanji corresponding to the character string (radical name) at the time of input is obtained, the reading range of the input character string at that time is changed. Although the neck conversion is performed, the radical conversion may be performed by changing the reading range only when the corresponding radical kanji is obtained at the time of input. In this case, all radical candidates can be obtained if radical kanji is possible in the input character string, so the latter method is preferable in practice.

【The invention's effect】

(1) According to the character conversion method of the present invention, since one character conversion is executed at the time of reading input, it is possible to obtain a desired kanji by one character conversion without requiring a troublesome operation.

After outputting the kana-kanji conversion result, one character conversion is executed in a state where one candidate of the conversion result is displayed or in a state where a candidate list of the conversion result is displayed. Compared with the method in which one character before or after the one candidate obtained as the conversion result is fixed, the desired candidate kanji can be easily obtained because the next candidate operation is not required.

(2) According to the character conversion method of the present invention, when a corresponding candidate cannot be obtained from the character string (reading) at the time of input, the reading range of the input character string at that time is changed to obtain a single Kanji character. Since the conversion is automatically executed, a desired kanji can be obtained by using the character string at the time of input without requiring the operation of single kanji conversion.

(3) According to the character conversion method of the present invention, radical conversion is continuously executed while changing the reading range of the input character string. Therefore, the registered radical name cannot be accurately known. Also, the desired kanji can be obtained.
