Description

Description: TECHNICAL FIELD The present invention relates to a word processor. (Prior Art) In a Japanese word processor having a kana-kanji conversion function, when one sentence composed of a plurality of phrases is input by a kana input using a character key of a keyboard, one sentence is converted into a character data string of many hiragana characters ( (Undetermined kana character string), and the undetermined kana character string is displayed on the display. When the kanji conversion key provided on the keyboard is operated to exchange the unconfirmed kana character string, the unconfirmed kana character string is converted to kanji, and the kanji converted character string is displayed on the display as a candidate character string. It is displayed. When 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. (Problems to be Solved by the Invention) In a conventional Japanese word processor, when a kana character string is input and then the kana character string is converted to kanji, the input character string is generally written in both hiragana and kanji. Even if it was used, it was converted to kanji, and it was not possible to change to hiragana notation even if it tried to select hiragana notation later. Then, in such a case, input while separating the kana character string and operate the no-conversion key at the delimiter you want to write in hiragana, or once confirm all candidate character strings, delete the kanji of the desired part Hiragana had to be re-entered there, and in each case the operation was very troublesome. (Purpose) The purpose of the present invention is to solve the above-mentioned problem, and when there are both Kana notation and Kanji notation in an input character string, when a change key is operated, either notation is given priority. If the selected notation is not the desired notation, the remaining notation can be selected, and the finally selected notation can be preferentially selected also in the next conversion. It is an object of the present invention to provide a word processor that can easily perform the above operation. (Means for Solving the Problems) In order to achieve the above object, a word processor according to the present invention comprises: input means for inputting a kana character; and a character string for determining a kana character input by the input means. And first information storage means for sequentially storing kana character string data representing readings, kanji notation data, and both kana and kanji as information on each of a large number of candidate character strings.
Notation information indicating whether the notation is generally used and both kana and kanji notation
A second storage unit for storing priority information indicating which one of the kana notation and the kanji notation is prioritized in a case where the kana notation and the kanji notation are stored in the first storage unit. A candidate character string corresponding to the kana character string data that matches the reading is searched in the second storage means, and based on the notation information, both kana and kanji notations are matched.
When not commonly used, the undetermined kana character string is used as a candidate character string for Kanji notation.
Conversion control, when both Kana and Kanji notation are generally used, conversion control for converting the undetermined kana character string into a priority candidate character string written in one notation form according to the priority information Means, changing means for changing the priority candidate character string converted by the conversion control means to the other notation form of the two notations, fixing means for fixing the priority candidate character string as a fixed character string, and the fixing means And rewriting control means for rewriting the priority information of the candidate character string corresponding to the determined character string determined according to the notation at the time of the determination. (Operation) In the word processor of the present invention having the above configuration, when a kana character is inputted by the input means, the first storage means sets the kana character inputted by the input means as an undetermined kana character string. Store them sequentially. Then, the conversion control means includes the first
Searching in the second storage means for a candidate character string corresponding to the kana character string data that matches the reading of the undetermined kana character string to be converted in the storage means of
Based on the notation information indicating whether both kana and kanji notations are commonly used,
If both the kanji and kanji are not generally used, the undetermined kana character string is
Converted to a character string candidate character string, and if both kana and kanji notation are commonly used
Converts the priority candidate character strings, denoted by one of the representation form in accordance with the priority information the undetermined kana string. The changing means changes the priority candidate character string converted by the conversion control means to the other notation form of both notations. When the operator operates the deciding means to select the priority candidate character string or the priority candidate character string changed by the changing means as a confirmed character string, the priority candidate character string is decided as a decided character string. Then, the rewriting control means rewrites the priority information of the candidate character string corresponding to the determined character string determined by the determining means according to 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. In FIG. 2, a keyboard 3 as input means is provided on a front side of a main body case 2 of the word processor 1, and a printer 4 is provided on a rear side. The keyboard 3 is provided with a liquid crystal display 5 having a plurality of lines each having 40 columns.

The kanji conversion key 7 is operated when the input kana character string is to be converted to a candidate character string mixed with kanji, and the next candidate key 8 is used to convert the candidate character string mixed with kanji converted when performing kanji conversion. Used to change to a candidate character string. Execute key 1
0 is used when the operator wants to make the candidate character string selected by the operator a confirmed character string,
It is also operated to execute other processing such as outputting a line feed command signal of a document. The cursor movement key 11 is used to move a cursor displayed on the display screen of the liquid crystal display 5. Next, an electric configuration of the word processor 1 will be described with reference to an electric block circuit diagram shown in FIG. A central processing unit (hereinafter referred to as CPU) 13 as conversion control means and rewrite control means built in the main body case 2 includes a read-only memory (ROM) 14 and a readable and rewritable memory (RAM). Working memory 15 is connected. The work memory 15 includes an input buffer unit 15a as a first storage unit for temporarily storing character code data input by the character key 6, and a learning memory as a second storage unit for temporarily storing a candidate character string. 15b and the like. The CPU 13 is connected to the keyboard 3 via a keyboard drive 16, connected to the liquid crystal display 5 via a display controller 17, connected to the printer 4 via a print driver 18, and connected to the code table 20. Have been. Also, CPU
Reference numeral 13 is connected to various memories such as the kanji dictionary memory 19 and the document memory 21. The ROM 14 includes a program memory 22 and a character generator 23 in which various control programs such as a Japanese word processor control program, a keyboard control program, a printer control program, a liquid crystal display control program, and the like for causing the word processor to operate variously are stored. ing. And the CPU 13
Operate according to the various control programs. The character generator 23 stores character pattern data such as characters and symbols displayed or printed in a dot matrix for each typeface. The kanji dictionary memory 19 stores various kanji data required for kana-kanji conversion, and is appropriately selected and read at the time of kanji conversion. That is, the kanji dictionary memory 19 generally stores character string data representing one reading 25, kanji notation data 26 corresponding to the character string data, grammar information 27, and both hiragana and kanji notation as shown in FIG. And notation information 28 indicating whether or not the notation is used in general, and priority information 29 indicating whether the notation of either the kana notation or the kanji notation is preferentially indicated when both notations are generally used is stored. I have. Further, codes corresponding to each character or symbol are stored in the code table 20, and signals are coded according to the code table 20 at the time of the input operation of the character key or the like. The document memory 21 stores character data input by an operator operating the character keys 6 and the like of the keyboard 3 in the input buffer unit 15a, and transfers and stores the character data when storing the character data. Has become. Next, the operation of the word processor 1 configured as described above will be described with reference to the flowchart of FIG. When the power is turned on, in step S1 (hereinafter simply abbreviated as "S1", the same applies to other cases), predetermined initial settings are made, and a so-called key scan state is set in S2, and the CPU 13 performs key input. Wait for it. If the operator operates any key on the keyboard 3, the determination in S2 is YES
The CPU 13 determines in S3, S6, S16, and S20 what key is operated based on the keyboard control program. When a key related to document input such as the character key 6 is operated, the determination in S3 is YES, and the CPU 13 sequentially stores the character data input in S4 in the input buffer unit 15a of the working memory 15, and controls the liquid crystal display. S5 based on the program
To display a document on the liquid crystal display 5 in accordance with the data stored in the input buffer unit 15a. The kana character string before the kana-kanji conversion (hereinafter referred to as an undetermined kana character string) is highlighted. Thereafter, the program returns to S2 again. When the kanji conversion key 7 is operated, the CPU 13 determines NO in S3 and YE in S6 based on the kanji conversion command signal input from the kanji conversion key 7.
In S7, the CPU 13 determines in S7 whether there is an undetermined character string in the input buffer unit 15a, and if not, performs error processing such as sounding a buzzer in S15, and then returns to S2. On the other hand, if there is an undetermined kana character string,
7 is determined as YES, an undetermined kana character string to be converted is read based on the cursor address, a candidate character string for reading corresponding to the learning memory 15b is searched in S8, and a candidate character string corresponding to the learning memory 15b is searched in S9. Determines whether a character string was present or absent. At first, since no candidate character string to be read is stored in the learning memory 15b, the process proceeds to S10, in which the Kanji dictionary memory 19 is searched for a candidate character string corresponding to the corresponding reading 25. Next, in S11, the CPU 13 determines whether or not the various data corresponding to the searched candidate character string has both the Kana notation and the Kanji notation based on the notation information 28. When the CPU 13 determines that both notations are present, the CPU 13 next determines in S12 whether or not the kanji notation is prioritized based on the priority information 29. If YES, the CPU 13 determines in S13 the kanji notation data based on the kanji notation data 26. The candidate character string is displayed on the liquid crystal display 5 in the notation, and the next key input is waited in S2. When the CPU 13 determines NO in S11, the CPU 13
If there is, the candidate character string is displayed on the liquid crystal display 5 in Kanji notation in S13, and if not, the candidate character string is displayed in Hiragana notation in S14 and the next key input is awaited in S2. When the CPU 13 determines NO in S12, the input buffer 1 is determined in S14.
The candidate character string is displayed on the liquid crystal display 5 in hiragana notation based on the character code of the undetermined kana character string to be converted stored in 5a, and waits for the next key input in S2. That is, in S14, the undetermined kana character string that has been highlighted is normally displayed, and the character string has been searched for as a hiragana candidate character string. Next, as described above, when the candidate notation displayed on the liquid crystal display 5 is not the desired notation, the next candidate key 8 is operated. Then, the CPU 13 determines YES in S2, NO in S3 and S6 based on the re-conversion command signal input by operating the next candidate key 8, and determines YES in S16. Then, the CPU 13 determines whether or not the candidate character string currently displayed on the liquid crystal display 5 has both Kana notation and Kanji notation based on the notation information 28 corresponding to the reading. If the CPU 13 determines YES in S17, the CPU 13 displays the remaining other notations on the liquid crystal display 5 based on the priority information 29 of the candidate character string currently displayed on the liquid crystal display 5 in S18, and proceeds to S2. Return to If the CPU 13 determines NO in S17, the CPU 13 removes the candidate character string currently displayed on the liquid crystal display 5 in S19 and proceeds to S8 to store the next new candidate character string in the learning memory 15b. If not, a search is made from the kanji dictionary memory 19 in S10. Next, when 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 determines YES in S2, NO in S3, S6, and S16 based on the signal input by operating the execution key 10, and determines YES in S20. When the determination is YES, the CPU 13 proceeds to S
At 21, the candidate character string currently displayed on the liquid crystal display 5 is displayed as a fixed character string,
The priority information 29 of the candidate character string is rewritten to information that gives priority to the notation at the time of finalization, and is transferred to the learning memory 15b together with the reading data 25, the kanji notation data 26, the grammar information 27, the notation information 28, etc. Return to As described above, the process returns to S2, where documents are sequentially created and the unconfirmed kana character string displayed on the liquid crystal display 5 is displayed as a confirmed character string. When there is character string data representing the reading corresponding to the determined character string, kanji notation data 26 corresponding to the character string data, grammar information 27, notation information 28 indicating whether or not there is both hiragana and kanji, and both notations Priority information 29 is stored which is rewritten with information that gives priority to the notation at the time of determination among the kana and kanji notations, and the word processor 1 learns. When the word processor 1 learns, when the same undetermined kana character string as previously input is input and the kanji conversion key 7 is operated to convert the undetermined kana character string to kanji, YES in S2, NO in S3, YE in S6 and S7
Since the character string data of the candidate character string corresponding to the reading of the previously undetermined kana character string is stored in the learning memory 15b, the corresponding candidate character string is searched in S8, and the process proceeds to S9. The determination of the CPU 13 is YES. Then, CPU
In step S11, it is determined in step S11 whether there is a kana notation or a kanji notation based on the notation information 28 corresponding to the reading, and the process proceeds to step S12, S13, or S14 based on the determination result. When keys other than the character key 6, the kanji conversion key 7, the next candidate key 8, and the execution key 10 are operated, the determinations of S3, S6, S16 and S20 are all NO, and the CPU 1
3 performs the above-described processing corresponding to each key in S22, and then waits for key input in S2. Next, a specific example will be described. If the power is turned on, initial settings are made, and characters are being input, S2
Assuming that an undetermined kana character string of “Unfortunately” has been input via S5, “Unfortunately” is displayed on the liquid crystal display 5. Then, when the kanji conversion key 7 is operated with the cursor positioned at this undetermined kana character string, the CPU 13 determines YES in S6 and S7 based on the kanji conversion command signal from the kanji conversion key 7, and in S9 It is determined as NO. Then, the CPU 13 searches the candidate character strings from the kanji dictionary memory 19 in S10, and determines whether or not both notations are present in S11 in the notation information 28 corresponding to the searched candidate character strings.
Is determined from Since the notation information 28 corresponding to the reading “unfortunately” is data with both notations, the CPU 13 determines YES in S11, and then determines C in S12.
The PU 13 makes a determination based on the priority information 29. Since this priority information 29 is the hiragana priority data in the kanji dictionary memory 19, the CPU 13 determines NO, and displays the kana notation "aiiniku" on the liquid crystal display 5 as it is in S14, and the next in S2. Wait for key input. If the displayed notation is not the one desired by the operator, the operator selects the next candidate key 8
Operate. Then, based on the re-conversion command signal from the next candidate key 8, the CPU 13 determines YES in S2, NO in S3, S6, and YES in S16. Then, after S17, the CPU 13 displays another notation of the candidate character string currently displayed on the liquid crystal display 5 in S18, that is, the kanji notation "unhappy" on the liquid crystal display 5, and returns to S2. Then, when the execution key 10 is operated next, the CPU 13 determines YES in S2, NO in S3, S6, and S16 based on the signal input by operating the execution key 10, and determines YES in S20. I do. When the determination of YES is made, the CPU 1
In step S21, the candidate character string currently displayed on the liquid crystal display 5 is displayed as a fixed character string in step S21. As shown in FIG. 5, the priority information 29 is rewritten to information giving priority to the kanji notation and read. Transfers various data corresponding to "Unfortunately" to the learning memory 15b,
Return to 2. In this way, the kana character string data and the like corresponding to the reading "Ainiku" are once stored in the learning memory 15, and then when the reading of the "Ainiku" is input, the CPU 13 in S8 at the time of converting the Kanji character of the "Ainiku" It is determined as YES, and the following S11 to S
Then, the processing shifts to 13 to display the word "unhappy" in Chinese characters. Note that the present invention is not limited to the above-described embodiment, and can be arbitrarily changed without departing from the spirit of the present invention. (Effects of the Invention) As described above in detail, according to the word processor of the present invention, the conversion key is operated when both the Kana notation and the Kanji notation are generally used in the input character string. When one of the notations is preferentially selected, if the selected notation is not the desired notation, the remaining notations are selected, and the finally selected notation is prioritized in the next conversion. This provides an excellent effect that the operation of the kanji conversion process can be easily performed. Also, only kanji notation is included in the input character string.
In general use, when a conversion key is operated,
Notation is not selected, only kanji notation is selected as a candidate character string,
For character strings in which only kanji notation is generally used,
It also has an excellent effect that the operation can be performed easily and quickly as before.
