Abstract

PURPOSE:To improve operability by performing KANA (Japanese syllabary)- KANJI (Chinese character) conversion and providing the function of reverse conversion, and making a return to the last state. CONSTITUTION:A conversion processing part 9 looks up a dictionary memory 7 to find KANJI corresponding to KANA stored in an input character buffer 4 and converts it into a KANJI code. When there are plural candidates, the starting KANJI is extracted to set pointer information on the candidate in a conversion result buffer 11, and the setting position is indicated with a current conversion state pointer 13. When reverse conversion is indicated, a reverse conversion processing part 10 subtracts the value of the current conversion state pointer 13 and points the conversion result information storage position right before the conversion result stored in the conversion result buffer 11. Consequently, the result of the previous conversion is made effective and thus candidates are selected in the opposite order. Then when the reverse conversion is indicated for the starting candidate, the KANJI is displayed in KANA again.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Technical Field of the Invention The present invention relates to a kana-kanji inverse conversion processing method, in particular, for example, a portable type Japanese word processor, etc., in which the pronunciation of a kana is input and the pronunciation is converted by pressing a conversion key. In addition to converting and displaying the corresponding kanji, it also has a reverse conversion function,
This invention relates to a kana-kanji inverse conversion processing method that allows the inverse conversion function to easily return to the previous conversion state.

(B) Prior Art and Problems Recently, document creation devices such as so-called Japanese word processors have been widely used. In a Japanese document creation device, for example, words or phrases input in kana characters are converted into kanji by operating a conversion key, and a document containing kanji is created. Various edits such as insertion, deletion, and copying of desired character strings are possible.

The created document is displayed on a display such as an LCD panel,
Printed on a printer as needed. When inputting Japanese on such a document creation device, pressing the conversion key converts the reading of the kana input so far into the corresponding kanji, and if the conversion key is pressed consecutively, homophones are converted. The next conversion candidates for the word are displayed one after another. Note that the reading of the kana is usually input manually using the kana character keys or by inputting the Roman characters.

By the way, conventionally, in the above-mentioned kana-kanji conversion method, if you accidentally press too many conversion keys, you cannot easily return to the previous state; for example, conversion candidates are selected periodically. , it was necessary to press the conversion key consecutively for the number of candidates and wait for the desired kanji to appear, or to press the "Cancel" key, reset the reading, and convert again. It is not uncommon for there to be 10 or more kanji as conversion candidates, and as a result, if a large number of conversion keys are pressed as described above, it takes a lot of effort and time to restore the conversion. .

(C) Object and Structure of the Invention The present invention aims to solve the above-mentioned problems, and by providing an inverse conversion instruction means, it is possible to easily change the conversion result to the previous one by the same operation as a normal conversion key. It is an object of the present invention to provide a kana-kanji inverse conversion processing method for a Japanese input device that can return to the original state. Therefore,
The kana-kanji reverse conversion processing method of the present invention includes a keyboard, a conversion dictionary in which kanji code information corresponding to the reading of the kana is registered in advance, and a display device, and the reading of the kana input from the keyboard is converted into A kana-kanji inverse conversion processing method in a Japanese input device that converts into kanji according to the contents of the above-mentioned conversion dictionary upon input of a key instructing kanji conversion, and inputs Japanese while displaying the conversion result on the above-mentioned display. an inverse conversion instruction means for instructing to return to the previous kanji conversion result for the kanji conversion for the homophone; an input character buffer in which the reading of the kana input from the keyboard is stored; and the input character. A kana-kanji conversion unit that converts the kana pronunciation stored in the buffer into a character string mixed with kanji by referring to the conversion dictionary, a conversion result buffer that stores the conversion results by the kana-kanji conversion unit, and and a current conversion state pointer pointing to a current conversion result storage position, and is characterized in that the current conversion state pointer is reset by an inverse conversion instruction by the inverse conversion instruction means to return the Kanji conversion result to the previous state.

Hereinafter, embodiments will be described with reference to the drawings.

(D) Embodiment of the Invention FIG. 1 shows the configuration of an embodiment of the invention, and FIG. 2 is a diagram for explaining the processing according to the embodiment of the invention.

In the figure, 1 is a keyboard, 2A to 2C are keys, 3 is a keyboard control unit, 4 is an input character buffer, 5 is a dictionary file, 6 is a file control unit, 7 is a dictionary memory, 8 is a kana-kanji conversion unit, and 9 is a A conversion processing unit, 10 is an inverse conversion processing unit, 1
1 is a conversion result bar, 12 is an attached word memory, 13 is a current conversion state pointer, 14 is a document editing section, 15 is a display buffer, 16 is a screen control section, 17 is a character generator (CG), and 18 is a display device. represents.

The embodiment shown in FIG. 1 is a portable type Japanese word processor that creates Japanese documents using the kana-kanji conversion method, and can also be used as a typewriter through so-called sequential printing. . The keyboard 1 includes keys for inputting kana pronunciations and various function keys for editing documents.In particular, the keyboard has two conversion keys, a non-conversion key 2B, and an expansion key 2C. There is. The two conversion keys are keys for instructing the conversion of the previously input reading into kanji. The no-conversion key 2B is a key for instructing to confirm the previously input reading as kana without converting it to kanji. Expansion key 2
0 is a key for instructing expanded functions of various function keys, and in this embodiment, when the non-conversion key 2B and the expansion key 20 are pressed simultaneously, it is used for instructing reverse conversion.

This inverse conversion instruction may be input by providing a key dedicated to inverse conversion.

Key information input from the keyboard 1 is stored in the input character buffer 4 by the keyboard control section 3. Note that the present invention can also be applied to a kana-kanji conversion method using Romaji input; in this case, Romaji-kana conversion is first performed, and the input character buffer 4 stores the kana character code corresponding to the Romaji reading. You can assume that it will be done.

The dictionary file 5 is a file on a storage device such as a floppy disk in which kanji code information corresponding to the reading of kana is registered in advance, and stores the kanji code information in predetermined block units. It is. The file control unit 6 controls reading dictionary information from the dictionary file 5. The dictionary memory 7 is a buffer that stores dictionary information read out in blocks from the dictionary file 5.

The kana-kanji conversion unit 8 includes a conversion processing unit 9 activated by the conversion key 2A, and an inverse conversion processing unit 10 activated by an inverse conversion instruction by the no-conversion key 2B and expansion key 2C.
It consists of The conversion result buffer 11 is a buffer in which conversion result information by the kana-kanji conversion unit 8 is stored.

The conversion processing unit 9 extracts from the dictionary memory 7 the kanji characters corresponding to the kana character code string stored on the input character buffer 4, and performs a process of converting them into kanji codes. When there are multiple candidates, the first candidate is extracted first, and pointer information regarding that candidate is set in the conversion result buffer 11. Then, the setting position is indicated by the current conversion state pointer 13. When the conversion key 2A is pressed again, the conversion processing unit 9 extracts the next homophone candidate, if any, and stores it in the conversion result buffer 11 with reference to the current conversion state pointer 13. Set the conversion result information to the next position. Then, the current conversion state pointer 3 is incremented to point to a new setting position. If there is no next candidate, the display returns to kana characters.

When an inverse conversion instruction is given, the inverse conversion processing unit 10 subtracts the value of the current conversion state pointer 3 and points to the conversion result information storage position immediately before the conversion result stored in the conversion result buffer 11. This process performs the following processing. By updating the current conversion state pointer 3 by the inverse conversion processing unit 10, the results of the previous conversion become valid, and candidates are selected in the reverse order. Note that in response to an inverse conversion instruction after returning to the first candidate, the display returns to kana display, and subsequent inverse conversion instructions are ignored.

The adjunct word memory 2 is a memory in which information about particles, auxiliary verbs, prefixes, suffixes, and other adjunct character parts regarding the conversion target in the input character buffer 4 is stored.

The document editing section 14 performs document editing processing based on the confirmed data after the conversion or non-conversion by the kana-kanji conversion section 8 is confirmed. It should be noted that the general editing processing contents in the document editing section 14 are well known, so detailed explanation will be omitted. The display buffer 15 stores character information to be displayed on the display 1B in accordance with, for example, JIS.
A buffer stored by code. In particular, during kana-kanji conversion, based on the information in the input character buffer 4, the information in the conversion result buffer 11 indicated by the current conversion state pointer 13 and the information in the adjunct word memory 12 are merged and set in the display buffer 15. .

The screen control unit 16 converts the character codes on the display buffer 15 into, for example, 24×2 by the character generator 17.
Each is converted into a 4-dot character pattern and displayed on the display 18.
This controls the display on the screen. The display device 18 is a display configured by, for example, a liquid crystal panel.

Next, referring to FIG. 2, an example of the processing according to the embodiment illustrated in FIG. 1 will be described.

For example, in dictionary file 5, for the pronunciation of ``kikou'', there are ``organization'', ``climate'', ``travel'', ``return to port'', etc.
Kanji codes are stored in the order of...

0 Suppose that "About Kikou" is input from the keyboard 1, and after this character string is stored in the input character buffer 4, two conversion keys are pressed. At this time, from the dictionary file 5, a block containing the pronunciation of "Kikou" which is the stem part is prepared in the dictionary memory 7, information about the first candidate "Mechanism" is extracted, and that information is used as the conversion result. It is set at the beginning of the buffer 11. The current conversion state pointer 13 is updated to point to its set position in the conversion result buffer 11.

In the conversion result buffer 11 shown in FIG. 2, the position information of the reading in the dictionary memory 7 is stored in the reading position X. In the expression position Y, the kanji code storage position of "mechanism" in the dictionary memory 7 is stored. Also,
For example, when there are particles, prefixes, suffixes, etc., information on them is stored in the connection information setting section Z. This includes information such as whether or not conjugations of verbs, etc. are allowed, and if so, what forms of conjugations are allowed.

Assume that the first candidate "Mechanism" is selected and the conversion key 2A is pressed while "About Mechanism 1" is displayed. As a result, the next candidate "Climate" is selected from the dictionary memory 7, and "About Climate" is displayed.

Then, the position of the pronunciation of "Kikou", the position of the expression of "Kikki" and their connection information are newly stored in the conversion result buffer 11, and the current conversion state pointer 13 points to the entry of the current conversion state "Kikki". will be updated to

For example, suppose that the user wants to confirm the conversion, but accidentally presses the conversion key 2A. Similarly, the next candidate "travel" in the dictionary memory 7-h is selected and displayed. Further, conversion information regarding "travel" is stored in the conversion result buffer 11, and the current conversion state pointer 13 is incremented. In the case of this embodiment, when converting the conversion result back to "climate", it can be easily changed back to "climate" with a single operation by instructing the inverse conversion. That is, when simultaneous keystrokes of the non-conversion key 2B and the expansion key 2c are detected, the inverse conversion processing unit 10 shown in FIG. 2. Move the current conversion state pointer 13 backwards so that it points to 2. This re-enables the conversion result "Climate" and displays "About Climate".

The above-mentioned inverse conversion instruction can be made valid any number of times while the conversion result is stored in the conversion result buffer 11. In response to an inverse conversion instruction after the display result returns to the first candidate "mechanism," the screen display is changed to unconverted hiragana, and the inverse conversion instruction is invalidated while hiragana is being displayed. Note that due to the size limit of the conversion result buffer 11, the configuration may be such that, for example, the inverse conversion instruction can be issued only once.

In the above example, the attached word part such as “about” is
Generally, adjunct words are displayed in hiragana, and even if the adjunct word includes kanji, there are almost no homophones, so they are managed separately in the adjunct word memory 12. Information on what types of attached words can be connected or not is determined by the information provided by the connection information setting unit Z.
Since it is determined in advance for each kanji to be converted, it is taken into consideration to prevent meaningless conversions.

(E) As described in detail, according to the present invention, even if you want to confirm the kana-kanji conversion but accidentally press too many conversion keys, you can easily convert it with one operation. The results can be reversed. Normally, we often do not know the number of times the desired conversion candidate kanji appears, so we press the conversion keys continuously, which often leads to the operation error of converting too much, but it is easy to do. Being able to return it improves operability.
