Abstract

PURPOSE:To obtain a desired HIRAGANA (cursive form of Japanese syllabary) character string even with the common Roman spelling and the different HIRAGANA expressions by converting sequentially a HIRAGANA expression into another one based on the input Roman spelling. CONSTITUTION:A Roman character/HIRAGANA converting circuit 8 checks the Roman character string inputted through a control circuit 6 by reference to a Roman character/HIRAGANA table 9 and transfers sequentially the HIRAGANA data having the high priority to the Roman spelling to the circuit 6. The checked Roman character string is stored in a text memory 7. Meanwhile a KANA (Japanese syllabary)/KANJI (Chinese character) converting circuit 10 retrieves a KANA/KANJI table 11 based on the KANA characters to be converted and writes the candidates of high priority into the memory 7 via the circuit 6. If these candidates are not identical with the desired KANJI, the KANA/KANJI conversion designing key is operated again on a keyboard 4. Thus the next candidate is written in the memory 7 and displayed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a romaji-kana conversion device which inputs hiragana to be input using romaji spelling and converts it into hiragana.

0002

2. Description of the Related Art Conventionally, when inputting hiragana, two methods are known: one is to input the hiragana directly from a keyboard, and the other is to input it in Roman letters and then convert it into hiragana. In the case of direct input of hiragana, the number of key touches is fewer than that of romaji spelling input, so it seems that the input speed is generally faster, but the input speed is actually faster when a dedicated operator who is familiar with the hiragana arrangement is used. limited to. For this reason, it is usually entered using the Roman alphabet.

[0003] Hepburn style, Kunrei style, and Japanese style are known for inputting Roman alphabet spellings, but each type of input uniquely determines the hiragana notation, so for example, in the Japanese word processor SWP-M60 manufactured by Sanyo Electric Co., Ltd., The input for "ji" is determined to be zi or ji, and the input for "ji" is determined to be di. However, in the original Roman alphabet spelling, both "ji" and "ji" are allowed to be written in the same way (
(excluding Japanese style), this resulted in some people having trouble inputting data.

Furthermore, if the vowels a, i, u, e, o, and y are input immediately after n, which represents a pellicle, is input, the result may not be as intended by the operator. for example"
I thought I was going to enter "ani," but when I entered "ani,"
For example, it becomes "ani".

[0005] In the above-mentioned Sanyo Electric Japanese word processor, in order to input the hiragana notation "n", "q", which is not used in general Roman alphabet spelling, is assigned. That is, when inputting the kana notation "An'i", the user must input "aqi".

[0006]

[Problems to be Solved by the Invention] As mentioned above, there is a problem in that the notations that are allowed in the original Roman alphabet spelling are not allowed. For this reason, even for people who know how to spell Roman characters, when inputting Kana notation using Romaji spelling, there are some Kana notations that cannot be input without knowing a special input method. The present invention attempts to solve such problems.

[0007]

[Means for Solving the Problems] In order to solve the above problem, the present invention provides a romaji-kana conversion device that inputs hiragana to be input in romaji spelling and converts it into hiragana. An input means for inputting a column, a Romaji-kana conversion means for sequentially converting the Romaji spelling inputted by the input means into Hiragana notation, and converting the Hiragana notation converted by the conversion means into a different Hiragana notation. Kana conversion instruction means for instructing.

[0008]

[Operation] As described above, the Romaji-Kana conversion device of the present invention includes a Kana conversion instruction means that instructs to sequentially convert Hiragana notation into a different Hiragana notation based on the input Romaji spelling. Even if the hiragana character strings are common but have different hiragana representations, a hiragana character string with the desired representation can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the Romaji-Kana conversion device according to the present invention is applied to a Japanese word processor will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the general structure of a Japanese word processor implementing the Romaji-Kana conversion device of the present invention. In the figure, reference numeral 1 denotes a display as a display means such as a CRT or LCD, and the display 1 is connected to a display control circuit 3 that controls display based on display data stored in a video memory 2, which will be described later. A bitmap format video memory 2 corresponding to the display screen of the display 1 is connected to the display control circuit 3.

The display control circuit 3 is controlled by a control circuit 6 which controls the entire device, and a keyboard 4 serves as an input means for inputting various operation commands and character strings to the control circuit 6.
is connected to a control circuit 6 via an input interface 5. The keyboard 4 provides various operation commands such as
Kana conversion instruction key 4A instructs the conversion of the kana notation that has been sequentially converted from the input romaji spelling to kana notation to a different kana notation, Kana kanji to instruct the conversion from the written kana characters to kanji notation It includes a conversion instruction key 4B, a cursor movement key, and an input mode setting key for setting the input mode to Roman alphabet spelling or direct kana input.

A text memory 7 for storing displayed characters, etc. is also connected to the control circuit 6, and character strings input from the keyboard 4 are stored in the text memory 7 via the control circuit 6. be done.

If the character string input via the control circuit 6 is a Roman character, the Roman character/hiragana conversion circuit 8 checks the character string using a Roman character/hiragana correspondence table 9 and sequentially converts the character string to the Roman character spelling. Hiragana data with a high priority is passed to the control circuit 6. This character string is stored in the text memory 7. Also, Kana/Kanji conversion circuit 10
searches the kana-kanji correspondence table 11 for the kana characters to be converted (underlined in FIG. 2 described later), and stores the candidates with high priority in the text memory 7 via the control circuit 6. Write. If the candidate is not the desired kanji, the user operates the kana-kanji conversion instruction key on the keyboard 4 again to write the next candidate in the text memory 7 and display it.

Next, a procedure for inputting Roman characters and converting them into Kanji using the device of the present invention will be explained. Figure 2 (A
) to (E) are schematic diagrams for explaining the transition of display states.

[0015] Now, as shown in Figure 2 (A), when trying to obtain the kanji ``easy'' by converting the kana spelled in romaji to kanji, first the roman character ``a'' is converted into kanji.
is pressed and sent to the control circuit 6 through the input interface 5.

Next, this Roman character "a" is sequentially sent to the Roman character/Hiragana conversion circuit 8 each time a character is inputted, in order to convert it into Hiragana notation. Therefore, referring to the Romaji/Hiragana correspondence table 9, the hiragana notation is converted to "a" and sent to the control circuit 6, and stored in the text memory 7. At the same time, the contents of the text memory 7 are transferred via the display control circuit 3. “A” is sent to display 1 as shown in Figure 3.
is displayed.

Note that in the hiragana notation shown in FIG. 2, an underline is added to inform the operator that the hiragana notation is to be converted into kanji.

When the next character "n" is pressed on the keyboard 4 and sent to the Roman/Hiragana conversion circuit 8, it is determined from the Kana/Romaji/Hiragana correspondence table 9 that the Roman character "a," The Roman letter "n" may be followed by letters such as "i, u, e, o, y, q, x".
Since the hiragana notation cannot be uniquely determined with a single character, the hiragana character is temporarily stored in the romaji/hiragana conversion circuit 8. Therefore, even if "n" is input, the display state does not change until the following character is input.
) remains displayed.

0019 The next character after the Roman alphabet “n” is the keyboard
When the romaji "i" is pressed from the code 4 and sent to the romaji/hiragana conversion circuit 8, the two characters, the previously temporarily saved romaji "n" and the current romaji "i", and the romaji/hiragana Based on the correspondence table 9, the hiragana ``ni'' is converted and sent to the control circuit 6. This character is stored in the text memory 7 and displayed on the display 1 as shown in Figure 2.
It becomes "ani" as in (C).

At this time, if this hiragana is the character to be input, an instruction is given from the keyboard 4 to perform kanji conversion. Then, the control circuit 6 sends the character to be converted into kanji in the text memory 7, that is, the underlined character string "Ani" to the kana/kanji conversion circuit 10, With reference to the correspondence table 11, the kanji character "brother" is sent to the control circuit 6. The control circuit 6 places this kanji character "brother" in the text memory 7, deletes unnecessary characters, controls the cursor position, etc. Display control circuit 3 displays the contents of this text memory 7.
As shown in Figure 2(D), the send display 1 is "Brother"
Display.

However, if the hiragana notation in FIG. - Give an instruction to convert to another hiragana notation using the kana conversion instruction key 4A of the code 4. Then, the control circuit 6 transmits the instruction and the kana notation "ani" to be converted to the romaji/hiragana conversion circuit 8, and based on the kana notation "ani", the romaji/hiragana conversion table 9 with reference to the Roman alphabet “a”
ni'' and then reconversion to hiragana notation.

At this time, after changing the syllables, a corresponding character is searched in the Roman alphabet/hiragana correspondence table 9. As a result, the romaji spelling ``ani'' is written in hiragana as ``An'i''.
and is displayed on the display 1 via the control circuit 6. This state is shown in FIG. 2(E). Therefore, if you instruct to perform kanji conversion using this hiragana notation, you can
) can be converted to the desired kanji ``Anki''.

[0023] In this example, a case was shown in which the syllables were reshuffled when converting to other hiragana, but there are other cases in which vowels are lined up or the letter "h" is continued. In some cases, conversion to long phonetic notation and vice versa, and
Needless to say, if there are other characters in the same syllable, conversion methods such as selecting those characters are also supported.

[0024]Also, when converting characters that have been written in hiragana to other hiragana, we have shown the case where they are converted back to Roman letters and then converted to hiragana again.
You may also create a separate hiragana correspondence table and refer to that table for conversion.

[0025]

[Effects of the Invention] As explained above, the Romaji-Kana conversion device of the present invention can obtain a Hiragana character string with the desired notation even if the Romaji spelling is common but the Hiragana notation is different. Users do not need to be familiar with the law, and operability can be improved.
