Abstract

PURPOSE:To enable selection from both notations by providing priority information to show which of the KANA (Japanese syllabary) notation or the KANJI (Chinese character) notation is to be given a priority. CONSTITUTION:In a KANJI dictionary memory, a character string data which represents one way of reading, a KANJI notation data corresponding to the character string data, notation information to show whether or not both notations of HIRAGANA (cursive form of Japanese syllabary) and KANJI are generally used, and priority information to show which of the KANA notation or the KANJI notation is notated with priority when both notations are generally accepted, are stored. When an operator inputs a HIRAGANA character string and presses a KANJI converting key whether or not the KANJI converting key is depressed is decided by S6. for the inputted character string, the corresponding string is retrieved by a learning memory and a KANJI dictionary memory, the presence or absence of both notations is checked by notation information by S11, whether or not the KANJI notation is given a priority is checked by the priority information at S12, and the corresponding HIRAGANA notation and KANJI notation are displayed in the display part.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to word processors.

(Prior art) In a Japanese word processor equipped with a kana-kanji conversion function, the letter key on the keyboard can be used to write the compound r! When one sentence consisting of one bunsetsu is entered using kana input, one sentence is stored as a large number of hiragana character data strings (undefined kana character strings), and the undefined kana character strings are displayed on the display. be done.

Then, when you operate the kanji conversion key provided on the keyboard, the unconfirmed kana character string is converted to kanji, and the kanji-converted character string is displayed as a candidate character string. is now displayed. If another candidate character string exists, the displayed candidate character string can be changed to another candidate character string by operating a next candidate key provided on the keyboard.

(Problem to be solved by the invention) When inputting a ephemeral character string in a conventional Japanese word processor and then converting the kana character string to kanji, the input character string is normally written in both hiragana and kanji. Even if the word was used in a kanji format, it would be converted to kanji, and even if you tried to select the hiragana notation later, you could not change it to hiragana. In such a case, input the kana character string by dividing it and operate the non-conversion key at the delimiter you want to write in hiragana, or confirm all candidate character strings and then delete the desired part of the kanji. Hiragana characters had to be re-entered there, and in both cases, the operation was extremely troublesome.

(Purpose) The purpose of this invention is to solve the above problems, and when an input character string has both hiragana and kanji notations, when the kanji conversion key is operated, one of the notations is given priority. If the selected notation is not the desired notation, the remaining notations are selected, and the finally selected notation can be selected preferentially during the next kanji conversion. To provide a word processor that can easily perform conversion processing operations.

(Means for Solving the Problems) The present invention comprises an input means for inputting kana characters, a first storage means for sequentially storing the kana characters inputted by the input means as an undefined kana character string, a second storage means for storing, as information regarding each of a large number of candidate character strings, kana character string data representing the reading, kanji notation data, and priority information indicating which of the kana notation and the kanji notation is given priority; , searches the second storage means for a candidate character string corresponding to the kana character string data that matches the pronunciation of the undetermined kana character string to be converted in the first storage means; a conversion control means for converting the candidate character string into a candidate character string expressed in one of the notation formats according to the priority information, and a candidate character string converted by the conversion control means into a candidate character string expressed in the other notation format of the above two notation formats or a candidate for the number. a changing means for outputting a reconversion command to the conversion control means to change the candidate character string to a character string; a determining means for determining the candidate character string as a final character string; and a candidate corresponding to the final character string determined by the determining means. The present invention is characterized by comprising a rewriting control means for rewriting the priority information of the character string according to the notation at the time of confirmation.

(Operation) When kana characters are input using the input means, the first storage means sequentially stores the kana characters input through the input means as an undefined kana character string. Then, the conversion control means searches the second storage means for a candidate character string corresponding to the kana character string data that matches the pronunciation of the undetermined kana character string to be converted in the first storage means, and A definite kana character string is converted into a candidate character string written in one notation format according to priority information. Further, when the changing means outputs a re-conversion command signal, the conversion control means changes the previously converted candidate character string to the other notation form of the two notations or to another candidate character string. When the operator operates the confirming means to select the candidate character string as a confirmed character string, the candidate character string converted by the conversion control means is confirmed as the confirmed character string. Then, the rewriting control means rewrites the priority information of the candidate character string corresponding to the confirmed character string determined by the determining means in accordance with the notation at the time of determination.

(Embodiment) An embodiment in which the present invention is embodied in a Japanese word processor will be described below with reference to FIGS. 1 to 5.

Working memory 1 consisting of ff1 possible memory (RAM)
5 is connected. The working memory 15 is a first memory for temporarily storing character code data input using the character keys 6.
an input buffer section 15a as a storage means, and a learning mechanism 1 as a second storage means for temporarily storing candidate character strings.
It is equipped with 5bW. The CPU 13 is connected to the keyboard 3 via a keyboard driver 16, to the liquid crystal display 5 via a display controller 17, to the printer 4 via a print driver 18, and to the code table 20. ing. Also, CPU1
3 is connected to various memories such as a kanji dictionary memory 19 and a document memory 21.

The ROM 14 includes a program memory 22 storing various control programs such as a Japanese word processor control program, a keyboard control program, a printer control program, and a liquid crystal display control program for operating the word processor, and a character generator 2.
3. The CPU 13 operates according to these various control programs. The character generator 23 stores character pattern data such as characters and symbols to be displayed or printed in a dot matrix for each typeface.

The kanji dictionary memory 19 stores data of various kanji necessary for kana-kanji conversion, and is appropriately selected and read out at the time of kanji conversion. That is, as shown in FIG. 4, the kanji dictionary memory 19 generally contains character string data representing one reading 25, kanji notation data 26 corresponding to the character string data, grammatical information 27, and both hiragana and kanji notations. Notation information 28 indicating whether the notation is used or not, and priority information 29 indicating which notation, kana notation or kanji notation, should be preferentially written if both notations are commonly used. .

Further, a code table 20 stores codes corresponding to each character or symbol, and a signal is encoded according to this code table 20 when inputting the character keys or the like. Further, the cultural memory 21 stores character data inputted by the operator by operating the character keys 6 of the keyboard 3 in the input buffer section 15a, and transfers and stores the character data when saving the character data. It has become.

Next, the operation of the word processor 1 configured as described above will be explained according to the flowchart shown in FIG.

When the N source is turned on, step S1 (hereinafter simply "Sl
After the predetermined initial settings are made at $2, the CPU 13 enters a so-called key scan state, and the CPU 13 waits for the key to be input manually.

When the operator operates any key on the keyboard 3, the determination in S2 becomes YES, and the CPU 13 determines the operated key based on the keyboard control program. Determinations are made in S6, S16 and 320.

When keys related to document input such as character key 6 are operated,
The determination in S3 is YES, and the CPU 13 stores the character data input in S4 in the input buffer section 15 of the working memory 15.
a, and the liquid crystal display 11111'O
Input buffer section 15a in S5 based on the IJ blockrum.
The document is displayed on the liquid crystal display 5 according to the data stored in the . In addition, the kana character string before being converted to kana-kanji (hereinafter,
(Undefined character strings) are displayed in reverse video. after that,
The program returns to S2 again.

When the kanji conversion key 7 is operated, the kanji conversion key 7
CPU 13 based on the kanji conversion command signal input from
The determination in S3 is N01, the determination in S6 is YES, and C
In S7, the PU 13 determines whether or not there is an undefined character string in the human buffer 7 section 15a, and if there is not, the process proceeds to S1.
In step 5, error processing such as sounding a buzzer is performed, and then the process returns to S2.

On the other hand, if there is an undetermined kana character string, the CPU 13 determines YES at 87, reads the undetermined kana character string to be converted based on the cursor address, and stores the corresponding pronunciation candidate in the learning memory 15b in S8. A character string is searched, and it is determined in S9 whether there is a corresponding candidate character string in the learning memory 15b. At first learning memory 1
Since no candidate character string to be read is stored in 5b, the process moves to S10, and the kanji dictionary memory 19 is searched for a candidate character string corresponding to the corresponding reading 25. Next, in step 811, the CPtJ 13 determines whether or not the searched candidate character string has both kana and kanji notation based on the notation information 28 among various data corresponding to the candidate character string. If the CPU 13 determines that both notations exist, then cp
In 312, ul 3 determines whether or not the kanji notation has priority based on the priority information 29, and if YES, the CPU 13
At step 13, the candidate character string is displayed in kanji notation on the liquid crystal display 5 based on the kanji notation data 26, and at step S2, the next key input is awaited.

When the CPU 13 determines NO in 811, the CPU 13
If there is kanji notation data 26, the candidate character string is displayed in kanji notation on the liquid crystal display 5 in S13, otherwise, in S1
At step 4, the candidate character string is displayed in hiragana notation, and at step 82, the user waits for the next keystroke. Further, when the CPU 13 determines No in S12, in S14, a candidate character string is displayed on the liquid crystal display 5 in hiragana based on the character code of the unconfirmed kana character string to be converted, which is stored in the input buffer 715a. Display and have the next key power at 82. That is, S14
In this case, the unconfirmed kana character string that was highlighted will be displayed normally, and the hiragana character string will be searched as a candidate character string.

Next, if the candidate notation displayed on the liquid crystal display 5 is not the desired notation as described above, the next candidate key 8 is operated. Then, based on the re-conversion command signal input by operating the next candidate key 8, the CPU 13 selects YES in S2, S3. S
No is determined at 6, and YES is determined at 816. Then, the CPU 13 determines whether the candidate character string currently displayed on the liquid crystal display 5 has both kana and kanji notation based on the notation information 28 corresponding to the reading thereof.

When the CPU 13 makes a YES determination at 817, CPtJ
13 displays the remaining other notation on the liquid crystal display 5 based on the two pieces of priority information of the candidate character string currently displayed on the liquid crystal display 5 in 318, and returns to 82. Also, CPU 13
When the determination is No in 817, the CPU 13 removes the candidate character string currently displayed on the liquid crystal display 5 in S19.
The process moves to S8, and the next new candidate character string is stored in the learning memory 15.
Search in b, and if there is no kanji dictionary memory 1 in S10.
Search from one.

Next, if the candidate notation displayed on the liquid crystal display 5 is the desired notation as described above, the execution key 10 is operated. Then, the CPU 13 selects YES in S2 based on the signal input by operating the execution key 10, 83.86.81
At 6, the determination is NO, and at 320, the determination is YES. If this determination is YES, the CPU 13 displays the candidate character string currently displayed on the liquid crystal display 5 as a confirmed character string in step 821, and sets the priority information 29 of the candidate character string to give priority to the notation at the time of confirmation. Rewrite the information and read data 2
5. Kanji notation data 26, grammar information 27, notation information 28
etc. are transferred to the learning memory 15b and the process returns to S2.

In this way, if you return to step 82 and create documents one by one and display the unconfirmed kana character strings displayed on the liquid crystal display 5 as confirmed character strings, the learning memory 15b will contain the unconfirmed characters that have been converted into kanji. Character string data representing the reading corresponding to the fixed character string, Kanji notation data 2 corresponding to the character string data
6. Grammar information 27, notation information 28 indicating whether there is both hiragana and kanji notation, and if there is both hiragana and kanji notation, information that gives priority to the final notation of kana or kanji notation. The destination information 29 that has been rewritten is stored, and this word processor 1 will perform learning.

When this word processor 1 has learned, when inputting an undefined kana character string that is the same as the previously input undefined kana character string, and operating the kanji conversion key 7 to convert this undefined kana character string into kanji, YES in S2, NO in 33, 86
and YES in S7, but since the character string data of the candidate character string corresponding to the reading of the previously input unconfirmed kana character string is stored in the learning memory 15b, the corresponding candidate character string is searched in S8. , the determination of the CPU 13 in S9 becomes YES. Next, in S11, the CPU 13 determines whether or not there is both kana notation and kanji notation based on the notation information 28 corresponding to the reading, and based on the determination result, selects either 312, S13, or S14. Transition.

When keys other than the character key 6, kanji conversion key 7, next candidate key 8, and execution key 10 are operated, the determinations of S3, S6, S16, and S20 all become No, and CPtJ13
In step 22, the above-mentioned processing is performed according to each key, and in step S2, the key is activated.

Next, a specific example will be explained.

When the power is turned on, initial settings are made, and characters are being input, if an undefined character string of "Unfortunately" is entered after going through steps 82 to S5, the LCD display 5 will display "
"Unfortunately" is displayed.

Then, when the kanji conversion key 7 is operated with the cursor positioned on this undetermined kana character string, the CPU 13 performs S6, S
7 is determined as YES, and S is determined as NO.

Then, in step 310, cpul 3 searches the kanji dictionary memory 19 for a candidate character string, and in step S11 determines whether or not there is both notation based on the notation information 28 corresponding to the searched candidate character string. The notation information 28 corresponding to the reading "unfortunately" is data with both notations, so in S11 the CPU
13 makes a determination of YES, and then in S12 the CPU 13 makes a determination based on the priority information 29. Since this recipient information 29 is data that prioritizes hiragana in the kanji dictionary memory 19, the CPU 13 determines No, and displays "Unfortunately" in kana as it is on the liquid crystal display 5 in S14.
Wait for the next key personnel at S2.

If the displayed notation is not the notation desired by the operator, the operator operates the next candidate key 8. Then, based on the reconversion command signal from the next candidate key 8, the CPU 13 makes a determination of YES in S2 and YES in N01816 at 33.86. Then, after passing through 817, the CPU 13 enters the notation of the candidate character string currently displayed on the liquid crystal display 5 in S18.
That is, the kanji notation "Jouso" is displayed on the liquid crystal display 5 and 82
Return to

Then, when the execution key 10 is operated next, CPtJ1
3 is YES in S2 based on the signal input by operating the execution key 1o, 83. S6. A NO determination is made in S16, and a YES determination is made in S20. When this determination is YES, the CPU 13 displays the candidate character string currently displayed on the liquid crystal display 5 as a confirmed character string in step 321, and changes the priority information 29 to give priority to kanji notation as shown in FIG. After reading the information, various data corresponding to "Unfortunately" are transferred to the learning memory 15b, and the process returns to S2.

In this way, the kana character string data etc. corresponding to the pronunciation "unfortunately" are temporarily stored in the learning memory 15, and then "
When the reading of ``Unfortunately'' is input, the CPU 13 determines YES in S8 when converting ``Unfortunately'' into Kanji characters, and thereafter moves to steps 311 to 813 to display the kanji notation ``Jijo''.

Note that the present invention is not limited to the above-mentioned embodiments, and can be arbitrarily modified without departing from the spirit of the present invention.

(Effects of the Invention) As detailed above, this invention provides that when the input character string is commonly used in both kana and kanji notation, when the kanji conversion key is operated, A notation is selected preferentially, and if this selected notation is not the desired notation, the remaining notations are selected, and the finally selected notation is selected preferentially during the next kanji conversion. This has the excellent effect of making the kanji conversion process easier.
