PURPOSE:To attain the appropriates input of a special description with simple operation even with a close writing conversion system, by supplying characters with a single KANJI (Chinese character) conversion even in a close writing conversion mode in order to give correction to the converted characters. CONSTITUTION:Both the extraction of word punctuation and the conversion into KANJI with the reading character strings which are continuously supplied in KANA (Japanese syllabary). Then the converted characters are displayed at a display part. A cursor is moved backs by an amount equal to a character to show 'HIROSHI' in KANJI with operation of a cursor control key. Here 'TAN KANJI' is displayed to show a single KANJI mode for an input line. Then the reading characters of another desired KANJI 'HIROSHI' are supplied with operation of a key. In this case, plural ways of reading if exist are supplied and the KANJI having all input ways of reading are selected. The KANJI 'HIROSHI' has two different reading ways 'HIRO' and 'KO'. Thus 'HIRO.KO' is supplied, and the corresponding KANJI is displayed at the right. Then the desired 'HIROSHI' is selected in KANJI.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a character string processing device, particularly a character string processing device that derives a corresponding string from an input string, such as a Japanese word processor or a translation machine. It concerns the character input method for Kana-Kanji conversion.

For example, in the "kana-kanji conversion" method widely adopted in Japanese word processors, a converted character string is generated from an input character string on a word-by-word or segment-by-segment basis. this is,
Since word processing such as confirmation and correction of Kanji words is performed on a word-by-word or segment-by-segment basis, there is a drawback that the frequency of operator intervention, that is, the frequency of keystrokes, is high.

On the other hand, in the so-called "solid writing conversion" method, word breaks are extracted and converted into kanji from a string of reading characters input continuously in kana or romaji notation. Therefore, since character strings are processed on a sentence-by-sentence basis, the operation is simple.

When inputting text using a keyboard, it may be necessary to modify the input character string due to an input error or a change of intention. Such corrections or modifications are required to be easily performed by simple operations.

Also, for example, special notation such as a person's name will not necessarily be converted into the intended notation even if you input the reading of that particular example9. Therefore, special notation is more efficient when converting from solid to kanji. It is desirable to be able to enter information in a good manner and to be able to modify it.

Traditionally, corrections or corrections were made by manipulating the "backspace" key and other function keys on the keyboard. For example, in Kana-Kanji conversion at the idiom level or phrase-cutting level, operate the back key to move the display cursor back, erase characters in order from the end of the input string, and then press the desired character key and the "No conversion" button. ” key 16 to add a new character to the end of a sentence.

However, in the solid kana-kanji conversion method, such a correction method that requires many key operations is not desirable. In other words, even though it is a solid kana/kanji conversion method, it is necessary to operate the "conversion" key or "no conversion" key to indicate the break between words or phrases. This not only requires the operator to make judgments each time he or she performs these complicated key operations;
The features of the solid kana/kanji conversion method are not fully utilized.

The object of the first major invention is to eliminate the drawbacks of the prior art and provide a character input method that allows special notation to be input appropriately with simple operations even in the solid writing conversion method.

In order to achieve the above-mentioned purpose, the present invention provides a second character input method for converting a first character string into a corresponding second character string by converting solid kana to kanji. The feature is that the reading of the kanji to be written in the character string is input as the first character string, and the reading is converted into the kanji reading. A detailed description will be given below based on one embodiment of the present invention.

Referring to FIG. 1, an embodiment in which the great invention is applied to a Japanese word processor is shown in a conceptual functional block diagram. As shown in the figure, this embodiment uses an input device 20 such as a keyboard, a display device 22, and a kana-kanji conversion algorithm 24 that executes solid kana-kanji conversion by referring to a conversion dictionary 28 such as a kanji dictionary or a grammar dictionary. and has.

The input device 20 has, in this embodiment, a reading character key for inputting reading (phonetic) characters such as kana or alphabet, and various cursor control keys. The cursor control key is used to control the display screen of the display device 22, which will be described in detail later.
The "cursor forward" key advances the cursor 40 displayed in the input character string display area 4B (Figure) and the cursor 48 displayed in the converted character string display area 44 (Figure 3), and moves the cursors 40 and 48 backward. cursor back key 52 (FIG. 3).

It also has function keys (Fig. 4) such as "confirm key" that transfers the converted character string after the kana-kanji conversion to the work area 37 (Fig. 2). The input device 20 also has a numeric keypad used when selecting kanji candidates, etc. The input device 20 further includes a mode designation key for designating the operation mode of the water device, which will be described in detail later.

Of course, the input device 20 has other function keys, but since these are not directly relevant to understanding the present invention, their explanation will be omitted. Note that in this specification, the term "character" includes not only kana or alphaben, but also punctuation marks and other symbols.

The display bag R22 may be a CRT character display device, for example.
The reading character string input into this system and the character string resulting from kana/kanji conversion are visually displayed. The display screen 38 consists of areas, or lines, in which a plurality of characters are displayed in a plurality of horizontal rows, and in this embodiment, it consists of a total of 24 lines. One of these days 〇, 1,000 foreigners 1. 3 minutes
As shown in FIG. 3, B consists of a converted character string display area 44 on the 22nd line and an input character string display area 4B on the 24th line. The remaining area 37 is a display work area where processing such as editing and calculation is performed on the data that has undergone kana-kanji conversion.

Character cursor 4 displayed in input character string display area 46
In this embodiment, 0 is an underline "-" located below a single character, and the word cursor 48 displayed in the converted string display area 44 basically displays the characters of the converted string in word units. This is to display black and white in reverse.

The converted character string display area 44 displays a converted character string that is a conversion result. In addition, input character string display area 48
, the conversion operation mode is displayed in the first half, and the input character string and the cursor 40 are displayed inside the parentheses [ ] 47 in the second half. Note that herein, the character string after conversion is referred to as a converted character string.

The operating modes of this device are broadly divided into a direct input mode and a kana-kanji conversion mode. The direct input mode further includes an alphanumeric mode and a katakana mode, both of which allow direct input into the work area 37 by manual input. The kana-kanji conversion mode is a mode in which an input character string is converted into kana-kanji to create a converted character string and displayed in the 1 display area 36. In this mode, by operating the confirmation key of the input device 20, the converted character string in the display area 36 is transferred to the work area 37 and displayed therein as a confirmed character string.

The Kana-Kanji conversion mode of this embodiment also includes Hiragana,
There are 10 types of modes: katakana, alphanumeric, proper noun, single kanji, symbol, ruby, period, fixed form direction, and two strokes. Furthermore, there are sub-modes such as Romaji input and full-width/half-width mode. Any of these modes can be selected using the mode designation key of the input device 20 described above.

The kana-kanji conversion algorithm 24 is a functional block that converts an input character string into a character string containing kanji, kana, and kanji using a commonly available kana-kanji conversion method. This has two main functions: a word extraction function that extracts 11 words from input reading character data, and a kanji conversion function that converts the parts of the extracted words that correspond to kanji into kanji. When a predetermined amount of input character strings is accumulated in the input temporary data buffer 2B, the kana-kanji conversion algorithm 24 takes in data indicating the input character string and indexes the conversion dictionary 28 such as a kanji dictionary and a grammar dictionary. Then execute the Kana-Kanji conversion process. Since the specific processing in these functions is not directly related to the understanding of the present invention, a description thereof will be omitted.

Kana-Kanji conversion algorithm 24 and other blocks are:
For example, it is advantageously realized by a processing system such as a microprocessor, and is shown in blocks according to its functions in the figure. For example, the input device 20 is associated with a temporary input buffer 2B that temporarily stores input signals generated in response to operations of these keys.

The editing processing unit 34 provides input data to the kana-kanji conversion algorithm 24 and converts the kana-kanji conversion algorithm 24
The Kana-Kanji conversion process, such as selection of candidate words output from Process.

In this embodiment, as shown in FIG. 3, the input character string, that is, the pronunciation, is displayed in brackets [ ], and a delimiter mark, for example, "/", is shown to indicate the delimitation of words.

The display circuit 30 is a circuit that controls the display device 22,
The display data is stored in the display memory 32. The display memory 32 has two storage areas: a conversion row area and an input row (reading) area. The contents of the editing processing section 34 are transferred to the conversion line area under the control of the display circuit 30. This is displayed by the display circuit 30 on the conversion line 44, ie, the 22nd line, of the display screen of the display device 22 shown in FIG. Further, the contents of the temporary input buffer 2B are transferred to the input row area under the control of the display circuit 30. This is performed by the display circuit 30 at the input display section 4 of the display screen.
6, that is: Displayed in [ko47] of JS24 line.

In the hiragana mode of the kana-kanji conversion mode, input device 2
When a reading character string is input by 0, it is temporarily stored in the input character string 2B and displayed in the input character string display area 4.
6. This is converted into a kanji-kana mixed sentence of the converted character string by the editing processing unit 34 and the kana-kanji conversion algorithm 24, and is displayed in the converted character string display area 4B.

By the way, in this embodiment, as described above, the mode of the apparatus is displayed at the left end of the input character string display area 4B of the display screen 38. For example, if the automatic kana-kanji conversion mode is selected, a message to that effect, ``own kana/kanji'', is displayed.

Furthermore, in this embodiment, the input mode of characters input in modes other than hiragana mode and proper noun mode in the kana-kanji conversion mode can be displayed at the left end of the input character string display area 46 in the kana-kanji conversion mode. When the cursor control key 20 indicates a character input in such a mode, the input mode of that character is displayed on the display device 22 under the control of the editing processing section 34 and the display circuit 30. That is, the editing processing unit 34 stores the input character string input number 1 inputted by the input device 20, and controls the display circuit 30 by referring to this when the character is specified later by the cursor control key. Then, the input mode of the character indicated by the cursor 48 is displayed on the display device 22.

In Kana-Kanji conversion mode, normally the converted character string display area 4
The cursor 48 at No. 4 indicates a single word in the converted character string by highlighting it. However, if it is at the position of a character input in a mode other than hiragana mode or proper noun mode, it will indicate a single character instead of a word, and the input mode for that character will be set to the left end of the input string display area 4B. indicate.

For example, in the example shown in FIG. 3(A), the word cursor 48
The word entered in hiragana mode and converted to kana-kanji
``Prime Minister'' and a display indicating the input mode of the character, that is, the kana-kanji conversion mode, ``self-kana single kanji'' is displayed at the left end of the input character string display area 4B. In that case, the input character string display area 4B displays the pronunciation character string "Shiyusho J" corresponding to the converted character string "Prime Minister."

Similarly, in the example shown in FIG. 3(B), the cursor (word) back key 52 is operated from the state shown in FIG. 3(A) to move the cursor 4
8 is moved to the character "Haku" input in single kanji mode. Therefore, a display "single kanji" indicating the input mode of the character, that is, the single kanji mode, is displayed at the left end of the input character string display area 4B. In this case, the input character string display area 46 does not display the reading character string. Thus, when the convertible cursor 48 points to a character input in the single kanji mode, the initial state of that mode is displayed.

When changing a character that has been input as a single kanji, input the reading in the same way as when inputting a single kanji, and operate the conversion key 60 to convert it into kana-kanji.

For example, as shown in (B), it is assumed that the user wants to change the input single kanji character ``Hiro'' to ``Hiroshi''. Letter r: Il
SelfIf −A&RΔ ryii+L+Table “−λ5
Since I can read the table, I use the character keys on the input device 20 to input "hi" and "ro" just as if forming a logical formula, then enter "・" on the numeric keypad, and then use the character keys to enter " The key is ``ko'' and ``u''. This means searching for kanji that can be read as either "hiro" or "kou" using logical product in the single kanji input mode. This input string is
"Hiro/Kou" is displayed in the input character string display area 4B (same (C)).

In this way, up to four readings of a single kanji can be input, but by separating the readings with a ``・'' on the numeric keypad, multiple readings can be input and the single kanji dictionary can be indexed by limiting the number of candidates. This combination may be three or more.

When the conversion key 80 of the input device 20 is operated, the editing processing unit 34 controls the kana-kanji conversion algorithm 24 and the dictionary 28 to search for candidate words of the converted string that satisfy the conditional expression of the input string "Hiro/Kou". In this embodiment, as shown in the same figure (Illll), a 94vi non-returnable screen is placed at the right end of the display area 38 in the form of a 3x3 matrix, that is, a virtual numeric keypad 54 arrangement. can be displayed.

In this example, four candidates were found.

Then, the operator operates the numeric keypad of the input device 20 to select these candidate words. In this example, "Hiroshi" is the intended character string, so operate the number key "8" to select it. In response to this, the processing unit 34 selects the candidate character string "Hiroshi" and replaces the character "Hiroshi" where the cursor 48 is located with it. This conversion result is transferred to the display circuit 30 and displayed in the converted character string display area 44 of the first display device 22.

At the same time, move Kurtz Jl/48 to the next word, "Prime Minister" in this example, and change the input mode for that character.
In other words, "Kana/Kanji" is displayed at the left end of the input character string display area 4B of the display device 22 ((E)).
. In this way, the character 'Hiroshi' was corrected to 'Hiroshi'.

Such processing is executed, for example, according to the operational flow of the editing processing section 34 and the display circuit 30, an example of which is shown in FIG. In single kanji input mode, if the input key is a character key (hiragana) (100).

(Half) Execute F4 point processing routine 102. When inputting four or fewer characters, set it in the single kanji input buffer (hos) and display it in the single kanji input field (108). 4
When exceeding the number of characters, if there is a kanji being displayed, it is output (110), and the work of the single kanji module is initialized (112). This operation is also performed when the enter key of the input device 20 is operated.

In order to enter multiple readings and create the logical formula for single kanji conversion mentioned above, press "・j" on the numeric keypad after inputting the first reading to convert the previously input string of readings to the first reading. Set the number of input characters to O (114), set it in the single kanji input buffer (10B), and display it in the single kanji input field (108).

When the conversion key 80 is operated, if the first conversion key is not manually operated (lie), the candidate string is incremented (1
18), Display the next candidate (120), If the first conversion key is input manually and the reading is input (122)
, the single kanji dictionary is indexed using the first reading (124), and if the search is successful, a candidate string is created (1213). If there is a second reading (128), the single kanji dictionary is indexed using the second reading (132), and if the search is successful, the first candidate string is limited by this, that is, the first searched candidate is Narrow down (+32). If candidate columns remain (134), the first candidate is displayed on the display device (13B).

Note that the embodiments described here are for explaining the present invention, and the present invention is not necessarily limited thereto, and modifications and variations that can be made by those skilled in the art without departing from the spirit of the present invention. Modifications are within the scope of this invention. For example, in the illustrated embodiment, the conversion line and the reading area are provided separately, but the conversion line may have a separate reading area and the reading characters may be stored and displayed in the conversion line.

As described above, the character input method according to the present invention allows characters to be input using @Kanji conversion even in solid writing conversion, and the converted characters can be corrected. Therefore, even in the solid writing conversion method, special notation can be input appropriately with a simple operation.
