Abstract

PURPOSE:To proceed to a single-KANJI (Chinese character) converting process with no input of the Japanese reading of KANJI even after the conversion of phrases, by providing a means which selects well-definedly a specific KANJI string out of those candidate strings retrieved by a retrieving means. CONSTITUTION:The Japanese reading of KANJI is supplied through a keyboard 1 according to the reading of a Japanese sentence and then converted into KANJI through the keyboard 1 when the proper Japanese reading is supplied by an indication. A retrieving circuit 3 retrieves a KANJI string corresponding to the due Japanese reading out of a phrase table 4. Then it is decided whether the candidate KANJI string corresponding the Japanese reading exists or not. If no corresponding KANJI string exists, a single-KANJI table 5 is retrieved. When the corresponding KANJI string is detected in the table 4, the presence or absence of an input signal is decided to check whether the user's desiring KANJI string exists or not. If no desired KANJI string is detected, and the user delivers this fact through the keyboard 1, the retrieval is started with the table 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a Japanese text input device for inputting Japanese text mixed with Kanji and Kana into a data processing device.

In an input device having a conventional kana-kanji conversion means, kana is converted into an idiom (including phrases) consisting of multiple kanji, but
It is not always possible to obtain an idiom that corresponds to the input pronunciation. Therefore, many products generally have a single kanji conversion function as an auxiliary kanji input method, but the single kanji function is executed by a method different from the operation of converting into compound words, for example, by pressing a specific function key. The reading you have entered up to that point will be invalidated, so you will need to enter the reading again.

Problems to be Solved by the Invention However, this method of starting single kanji conversion has a problem in that the same pronunciation must be input again from the keyboard because it is unrelated to compound word conversion.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a Japanese text input device that moves to single kanji conversion without inputting the pronunciation even after inputting the pronunciation and converting the idiom.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has an objective of solving the above-mentioned problems.If the corresponding kanji string does not exist after the idiom is converted, the idiom is converted automatically or according to the user's instruction, for example, by pressing a conversion key. ,
It performs single kanji conversion based on the reading that has already been input.

Effects of the present invention With the above-described configuration, the single kanji conversion is not separated from the compound word conversion at all, but the reading once input is shared and used by both, and different conversions are smoothly linked.

Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a keyboard, which is used to input readings, instruct conversions, and select candidate kanji strings. A display device 2 displays the pronunciation input from the keyboard 1, the corresponding kanji string, and the input sentence. 3 is a search circuit,
4 is an idiom table, and 6 is a single kanji table.The search circuit 3 searches the idiom table 4 and the single kanji table 5 for a kanji string corresponding to the pronunciation input from the keyboard 1, and the kanji string obtained as a result is It is stored in the document memory 6. Each of the above devices is controlled by a control device 7.

FIG. 2 is a flowchart showing the procedure for inputting Japanese sentences using the apparatus of this embodiment. The user inputs the reading from the keyboard 1 according to the reading of the Japanese sentence (step 21).

After inputting an appropriate reading, the user uses the keyboard 1 to instruct that the reading be converted into kanji, and the control circuit 7 determines whether the input signal indicates a conversion key (step 22).

The search circuit 3 searches the idiom table 4 for a kanji string corresponding to the reading (step 23).

In step 24, it is determined whether or not there is a candidate for a kanji string corresponding to the reading, and if the corresponding kanji string does not exist, then the single kanji table 6 is searched (step 2
6). If the corresponding kanji string exists in the phrase table 4 in step 24, then in step 26 it is determined whether there is an input signal indicating whether the kanji string desired by the user is present. If there is no kanji string desired by the user, the user instructs the user to that effect using the keyboard 1, and the search proceeds to the single kanji table 5 (step 25). If the desired kanji character string exists among the kanji strings obtained by the search process, the user selects the kanji string (step 27); if the kanji string does not exist, the process is interrupted (step 2B).

Effects of the Invention As described above, according to the present invention, it is possible to smoothly switch between compound word conversion and single kanji conversion, and the reading can be input only once.

Claims (1)

[Claims] a keyboard having a key for inputting Japanese sentences and a conversion key for converting the reading inputted from the key into a kanji string; an idiom table that associates idioms with readings;
a single kanji table that associates a single kanji with a reading, and a search means that searches the compound table or the single kanji table for a reading input from the keyboard and outputs a kanji string corresponding to the reading. , means for uniquely selecting a specific kanji string from among the candidate kanji strings searched by the search means, and the idiom table is searched with priority, and when a kanji string corresponding to the reading does not exist, teeth,
If the desired kanji string is not found among the candidate kanji strings obtained by automatically searching the single kanji table or by searching the compound word table, the user can input the kanji character string using the keyboard. A Japanese text input device characterized in that it is possible to search a kanji table and obtain a kanji string without re-entering the reading.
