Abstract

PURPOSE:To improve an efficiency in inputting Japanese by displaying a symbol discriminating whether a candidate Chinese character has OKURIGANA 'kana' added after a Chinese character to show its Japanese inflection or not when displaying the candidate KANJI (Chinese character) inputted by HIRAGANA (cursive Japanese syllabary). CONSTITUTION:When a KANJI conversion/selection key is pushed down after, for instance, HIRAGANA 'aoi' is inputted through a key, a CPU 41 retrieves the relevant KANJI from a KANJI dictionary area 49 according to the longest coincidence method. The KANJI without OKURIGANA coinciding with a reading of the key inputted HIRAGANA 'aoi' is retrieved, the candidate KANJI is stored in a candidate KANJI buffer area 55, the pattern data relating to the candidate KANJI data is read from a pattern data area 51, the first discriminating symbol white round mark is displayed at a head column position of a candidate KANJI display part and the candidate KANJI is displayed. When there is no required KANJI in the candidate KANJI without OKURIGANA and a KANJI conversion/selection key is pressed down, whether the candidate KANJI with OKURIGANA to 'ao' is present or not is decided, a discriminating signal black round mark is displayed and the candidate KANJI with OKURIGANA is displayed after the second column and completed.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention displays a plurality of candidate kanji according to the pronunciations input in kana, and selects the desired kanji from among them to enable Japanese input. Regarding possible document input devices.

[Prior Art] In conventional document input devices, when a kanji conversion/execution key is operated after manually inputting a hiragana key according to the reading of a required kanji to be input, the input device inputs the hiragana reading manually from a kanji dictionary. Candidate kanji are displayed on the display device.

Then, the user selects the desired kanji to be input from the displayed candidate kanji and performs Japanese input.

[Problems to be Solved by the Invention] However, when the above-mentioned conventional document input device displays candidate kanji based on the pronunciation input in kana, was displayed without the okurigana. Then, when a candidate kanji with an okurikana is selected, the kanji is inputted with an okurikana attached. Therefore, when selecting a desired kanji from among the candidate kanji, it is not possible to distinguish whether the displayed candidate kanji is with or without okurigana, making it difficult to input Japanese efficiently. There wasn't.

[Object of the Invention] In view of the above-mentioned conventional drawbacks, it is an object of the present invention to determine whether or not the candidate kanji has an okorikana along with the candidate kanji when displaying the candidate kanji according to the pronunciation inputted in kana. An object of the present invention is to provide a document input device that can efficiently input Japanese by displaying symbols for identifying the characters.

[Means for Solving the Problems] For this reason, the present invention, when displaying a candidate kanji without an okurikana, displays a first identification symbol indicating that there is no okurikana on the display means together with the candidate kanji, and When displaying a candidate kanji having an okuri kana, a second identification symbol indicating that the candidate kanji has an okurikana is displayed on the display means together with the candidate kanji.

Next, an outline of the Japanese input method will be explained.

First, when the plate name key 13 is pressed, the CPU 41 transitions to the plate master manual mode. When the character key 9 is pressed, the CPU 41 stores the code corresponding to the character key 9 in the input buffer area 53. Further, the display drive circuit 67 transfers data from the pattern data area 51 to the display buffer area 5 based on the code stored in the input buffer area 53.
Input display section 5 based on the pattern data transferred to 7.
Display the flat name entered manually in a. When the no-conversion key 17 is pressed in the above state, the CPLJ 41 determines that the input data is a flat name, and moves on to the next process. on the other hand,
When the kanji conversion/selection key 15 is pressed after inputting the flat name, the CPLJ 41 transfers the candidate kanji corresponding to the reading of the flat name entered manually from the kanji dictionary area 49 to the candidate kanji buffer area 55, and The candidate kanji is displayed on the kanji display section 5b. When a desired kanji is selected from among the candidate kanji displayed on the candidate kanji display section 5b by operating the number keys, the CPU 41 converts the code of the flat name stored in the input buffer area 53 into the selected kanji. The required kanji is rewritten into a kanji code and displayed on the input display section 5a.

Next, the candidate kanji display process is shown in Figure 3, which shows the flow of the candidate kanji display process, and Figure 4 (A), which shows the display state of candidate kanji without okuri kana and the display state of candidate kanji with okurikana.
Go to the back town according to (B).

For example, after manually inputting the flat name ``Aoi'', converting it into kanji/
When the selection key 15 is pressed, the CPU 41 searches the kanji dictionary area 49 for the corresponding kanji using the longest match method. That is, it is determined in step 71 whether or not the sending kana identification flag 63 has been reset, and if the determination result is YES, the kanji dictionary area 49 is searched in step 72, and the kanji dictionary area 49 is searched for the key-entered flat name "Aoi". Search for kanji without okuri kana that matches the reading.Then, go to kanji dictionary area 49.
Candidate kanji without okurikana that matches the reading ``ao'' retrieved from ``Aoi'' is stored in the candidate kanji buffer area 55.

Next, in step 73, it is determined whether the number of candidate kanji characters stored in the candidate kanji buffer area 55 has reached the required number that can be displayed on the candidate kanji display section 5b. Said step 7
If the determination in step 3 is No, it is determined in step 74 whether or not all candidate kanji without okurikana that match the keyed reading ``aooi'' have been searched. First, if the determination in step 74 is No, the process returns to step 72.
If the determination result in step 4 is YES, the process moves to step 75, where the okukana identification flag 63 is set, and then the process moves to step 76. Also, if the number of candidate kanji stored in the candidate kanji buffer area 55 reaches the required number that can be displayed on the candidate kanji display section 5b and the determination in step 73 is YES, the process moves to step 76 and the candidate kanji buffer area The first mark indicates that the candidate kanji stored in 55 is a kanji without okuri kana.
The data corresponding to the identification symbol 110 I+ is set in the first storage position of the candidate kanji buffer area 55. Next, in step 77, data indicating the first identification symbol ``O'' stored in the candidate kanji buffer area 55 and pattern data related to the candidate kanji data are read from the pattern data area 51, and the pattern data is displayed in the display buffer area 57.
As shown in FIG. 4(A), the first identification symbol 110 I is displayed at the first digit position of the candidate kanji display section 5b.
After displaying + and candidate kanji in the second and subsequent digits, the process ends.

When a specific kanji is selected from the displayed candidate kanji using a numeric key or the like, the CPLJ 41 inputs the kanji and resets the sending kana identification flag 63.

On the other hand, if the desired kanji is not found among the candidate kanji without okurikana, and the kanji conversion/selection key 15 is further pressed,
The candidate kanji display program shown in FIG. 3 is executed again. In this case, since the sending kana identification flag 63 has already been set in step 75, the determination in step 71 is NO.

Then, in step 81, it is determined whether or not there is a candidate kanji in the kanji dictionary area 49 that has the reading ``ao'' with a kana added to it.
is not registered and the determination at step 81 is No, the process ends. On the other hand, if the kanji dictionary area 49 has registered the ``ao'' with a kana, and the determination in step 81 is YES, step 82 selects a candidate kanji corresponding to ``ao'' with a kana from the kanji dictionary area 49. is read out and set in the candidate kanji buffer area 55. Then, in step 83, it is determined whether the number of candidate kanji set in the candidate kanji buffer area 55 has reached the required number that can be displayed on the candidate kanji display section 5b. If the determination in step 84 is No, it is determined in step 85 whether all candidate kanji corresponding to ``ao'' with okurikana have been searched, and if the determination is No, the process returns to step 82.The conditions described above. If all the candidate kanji corresponding to the candidate kanji are searched and the determination in step 84 is YES, the sending kana identification flag 63 is reset in step 85, and then the process moves to step 86, and the candidate kanji set in the candidate kanji buffer area 55 is Even if the required number has been reached and the determination in step 84 is YES, the process moves to step 86. In step 86, the second identification symbol "・After setting the data, as shown in FIG. 4(B), in step 87, the identification symbol "゛・" is displayed at the first digit position of the candidate kanji display section 5b, and the second and subsequent digits are sent with kana. Display the candidate kanji and exit.

In this way, in this embodiment, when displaying candidate kanji in the candidate kanji display section 5b according to the pronunciation input as a flat name, the first identification symbol "○" is added to the candidate kanji without an okigana, and Since the second identification symbol "." is displayed for the candidate kanji with an okurikana, it is possible to easily confirm whether or not the displayed candidate kanji has an okurikana.

[Effects of the Invention] As described above, the present invention provides a symbol for identifying whether or not the candidate kanji has an okurikana, along with the candidate kanji, when displaying the candidate kanji according to the reading input as a plain name. By displaying , it is possible to provide a document input device that can efficiently input Japanese.
