Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to kanji input from a keyboard,
The present invention relates to a kanji input device suitable for inputting sentences containing kanji.

[Conventional technology]

Conventional kanji input methods for computer devices, etc. include all character arrangement methods such as kanji tablets and Japanese type, methods in which kanji are coded and the code is input from the keyboard, or the reading gana of the onkun is input from the keyboard. A method in which homophones corresponding to the reading are obtained through kana-kanji conversion and the desired kanji is selected from among them; a triangular notation method in which a kanji is obtained by inputting the three radicals that make up the kanji; Furthermore, input using radicals and their constituent positions is discussed in Japanese Patent Application Laid-Open No. 129935/1983.

[Problem that the invention seeks to solve]

In the above-mentioned prior art, when a user wants to input a specific kanji, the desired kanji is obtained by inputting the pronunciation of the onkun of that kanji. Therefore, there was a problem in that input could not be made without knowing the pronunciation of the onkun registered in the table for the desired kanji.

In addition, in the triangular alphabet system, the radicals of kanji must be placed on the key tops of the keyboard, and since three radicals of kanji are input, the exact form of the desired kanji must be known. There was a problem.

Furthermore, the method of inputting radicals and their constituent positions described in JP-A-56-129935 does not take into account the case where there are multiple radicals with the same sound. The problem was that you couldn't input it unless you knew it.

The purpose of the present invention is to determine the partial letters that make up a desired kanji without providing special keys on the keyboard, in cases where the shape of a desired kanji is known but the reading of the onkun is unknown. By inputting the constituent position information of the radical, it is possible to input a kanji whose reading of the onkun is unknown, and also to obtain a kanji input device that is capable of inputting the kanji even if the reading of the radical is unknown. There is a particular thing. Alternatively, it is possible to input kanji when the shape of the desired kanji is ambiguous.

[Means for solving problems]

In order to achieve the above object, according to the present invention,
a first radical selection means for inputting reading information of radicals constituting a kanji and selecting and specifying one desired radical; and second radical selection means for selecting and specifying a neck. Furthermore, a selection means is provided for selecting and specifying either one of the first radical selection means and the second radical selection means, and the first radical selection means and the first radical selection means selected by the selection means are provided. and an input means for inputting desired information into either one of the radical selection means, whereby one radical constituting a desired kanji can be selected according to its reading or number of strokes. Then decide. In addition, a certain key on the keyboard can be assigned as a key to indicate which part of the desired kanji, such as hen, tsukuri, kanmuri, ashi, niyo, etc., that radical forms. Specify. A table is searched for a Kanji character corresponding to the two elements of the specified radical and its constituent position, the candidates are displayed on a display device, and a desired Kanji character is selected from among them.

[Effect]

FIG. 1 shows the basic processing procedure for inputting Chinese characters using radicals and their constituent positions. In the figure, step 1a is to read the radical or select it from the radical menu.
This is a part for inputting a partial radical constituting a desired kanji, and constitutes radical selection means. This radical selection means inputs reading information of radicals constituting a kanji, first radical selection means selects and specifies one desired radical, and inputs information on the number of strokes of radicals constituting a kanji. , and second radical selection means for selecting and specifying one desired radical. Furthermore, a selection means is provided for selecting and specifying either one of the first radical selection means and the second radical selection means, and the first radical selection means and the first radical selection means selected by the selection means are provided. and an input means for inputting desired information into either one of the radical selection means, whereby one radical constituting a desired kanji can be selected according to its reading or number of strokes. Then decide. step
1b indicates that the radical entered in step 1a is
What parts of the desired kanji are made up?
This part is input by using specific keys corresponding to the structure, crown, leg, etc., and constitutes a configuration selection means. A kanji table is a kanji table for each radical that is composed of table search information specific to each radical that limits the radical, kanji data registration position information for each constituent position for that radical, and candidate kanji information. The number of tables is as many as the number of radicals, and the number of steps is
Step 1c is a part that searches for the part corresponding to the input information in the above table using the information of the radical and its constituent position input in Step 1a and Step 1b, and Step 1d is a part that searches for the part corresponding to the input information in Step 1c. This part displays the Kanji candidates registered in the detected part, and step 1e is the part to select a desired Kanji from among the displayed Kanji candidates. These steps 1d and 1e constitute a kanji selection means.

This kanji input program is activated by an operator's key input requesting kanji input on an operating system (hereinafter referred to as OS), an application program (hereinafter referred to as AP), or a user program.

Through the above operations, a desired Kanji character can be obtained by inputting the radical of the Kanji character and its constituent position.

[Example] Hereinafter, the first embodiment of the present invention will be described.
In addition to the figures, Figures 2, 3, 4, 5, and 6
This will be explained with reference to FIGS. 7, 8, and 9.

FIG. 2 is a block diagram showing the basic configuration for realizing this embodiment. In the same figure, 2
d is the OS program, 2e is the AP, 2
f is a user program. When a keyboard input request is output from these programs, a keyboard input request is output from the kanji input program 2c to the keyboard interface program 2b. In the keyboard interface program, codes corresponding to keys input from the keyboard 2a are stored in a keyboard buffer, and each time a keyboard input request is made, a key code is taken out from the keyboard buffer and returned to the kanji input program. Therefore, in the kanji input program,
The returned key code is processed into a specific kanji code and returned to the OS, AP, and user program.

FIG. 3 is a flowchart showing the processing procedure in this embodiment. In the figure, first, in step 3a, it is determined whether the radical input method is by selecting a radical from a menu. This determination is made by assigning a certain key as a radical menu selection mode designation key and determining whether or not this key is input. In this embodiment, the 〓 key is assigned.
Use the menu selection mode designation key to move to the radical menu selection mode, and if the selected item here is radical reading input, proceed to step 3b.
Enter the reading of the radical using the keyboard. Next, in step 3c, the user specifies which part of the desired kanji character the radical input in step 3b constitutes. In this case, the designation method is performed using cursor movement keys. FIG. 10 shows the correspondence between the positions of kanji radicals and cursor movement keys. If the designated kanji radical is hen as in the part shown in FIG. 10a, the ← key is input. In the case of a structure like the part shown in FIG. 10b, input the → key. If it is a crown like the part shown in Figure 10c, press the ↑ key. In the case of feet, as in the part 10d of the same figure, input the ↓ key. Figure 10e, 10f, 10
In other cases, such as the , , , part of g, niyo, kakoi, etc., enter the 〓 key. Next, proceed to step 3d, and search the homophone radical table to see if there are multiple radicals based on the pronunciation of the input radical. The structure of the homophone radical table is shown in FIG.

This table only registers pronunciations with homophone radicals, and is divided into records for each radical pronunciation. The structure of each record is: the start address of the next record, the reading length of the radical, the reading of the radical, the data of the homophone radical corresponding to the reading, and finally, the record end mark is a hexadecimal FF.
Contains. Records with the above structure are registered individually for each pronunciation that has the same sound and multiple radicals. When searching this table, first the reading length of the input radical is calculated, and the calculated reading length is compared with the reading length in the record starting from the first record in the table. If the pronunciation lengths are the same, the input pronunciation is compared with the pronunciation in the record, and if the pronunciations match, it is determined that the pronunciation has a homophone different radical. In addition, if the reading length is different or the reading is different, the records are sequentially read by the next record start address until the last record in the table.
In other words, a similar search is performed up to the record where the next record start address is FFFF in hexadecimal, and if a record with both reading length and reading matching is not found, then a homophonic variant is searched for the reading of the input radical. It is determined that the neck does not exist. If no homophonic radical is found through the above search, the input pronunciation is unique and the process proceeds to step 3. If there is a homophone radical, proceed to step 3f, display the radical data registered in the detected record on the CRT screen as a radical candidate menu, and select one from among these candidates. Specify a radical. An example of the screen display in this case is shown in FIG. The figure shows an example in which homophone different radicals are displayed when the reading of the radical "hi" is input. Once the radicals have been determined, if the radicals have the same sound, it cannot be limited to a specific part based on the reading alone, so if the radical has the same sound, a numerical number is added to the reading to make the reading unique to each radical. . This conversion is performed in step 3r using a radical reading table. The structure of the radical reading table is shown in FIG. The radical reading table is composed of records for each radical, and each record consists of a radical code and a reading specific to that radical. Then, the radical codes are compared from the first record of the table, and if they match, the reading registered in that record is acquired as the reading of the specified radical.

Next, in menu selection mode, if you choose to specify a radical by menu selection, the step
Enter the number of strokes of the radical in step 3g, and display the radical candidates with the specified number of strokes on the CRT in step 3h.
Display on screen. An example of CRT screen display in this case is shown in FIG. Next, in step 3i, select a radical from the menu, and in step 3j, enter the constituent position of the selected radical in the same way as when inputting by reading.
Specify using the cursor movement keys. Then move on to step 3k, which converts the selected radical into a unique reading.

Through the above processing, information on the reading specific to the specified radical and its constituent positions has been obtained. Therefore, in step 3, the kanji table is searched using the acquired information. The structure of the kanji table is shown in FIG. 9. In the figure, 9a is a primary index section corresponding to the reading, 9b is a secondary index section corresponding to the configuration position, and 9c is a secondary index section corresponding to the configuration position.
is the data part of kanji candidates corresponding to the reading and composition position. The primary index is divided into records corresponding to the reading of the radical, and each record has the start address of the next record inside the primary index,
The reading length of the radical, the reading of the radical, and the start address of the corresponding secondary index are registered. The secondary index contains the start address of the kanji data corresponding to the position of the radical. In FIG. 9b, address 1-1 is the address for Hen, address 1-2 is the address for Tsukuri,
Addresses 1-3 indicate the addresses for the crown, addresses 1-4 indicate the addresses for the legs, and addresses 1-5 indicate the addresses for other structures such as the bow and the shield. If there is no corresponding kanji candidate here, hexadecimal FFFF is registered, such as address 2-4. The reading information of the radical held there is compared with the reading in the primary index of the kanji table, starting from the first record, and the corresponding secondary index address is obtained. If there is no record corresponding to the reading, the process proceeds to step 3m, and returns to step 3a as the reading is invalid, and inputs the radical again. If a corresponding record exists,
Proceeding to step 3n, the secondary index is referred to based on the held configuration position information to obtain the record start position of the corresponding kanji candidate data. and,
Kanji candidates in that record are displayed on the CRT screen. An example of the CRT screen display at this time is shown in FIG.
The operator selects a desired kanji from the displayed kanji candidates. Next, in step 3o, the keys input by the operator are the cursor movement keys (←, →, ↑,
↓, 〓), and in that case, switch the corresponding record from the secondary index in step 3p, and again in step 3n,
The kanji candidates in the switched kanji table are displayed on the CRT screen. Next, if the input is not the kanji composition position designation key, the process goes to step 3q, and it is checked whether the radical reading input or the radical menu request key has been input, and in that case, the process goes to step 3r. In step 3r, the same processing as in steps 3a to 3m is performed to search the table corresponding to the secondary information of the input radical. Once the corresponding table is detected, it is compared with the table detected based on the primary information of the radical, and the kanji included in both tables are stored in memory as kanji candidates that have both the primary and secondary information of the radical. Register in the area. and step
Return to 3n and display the registered kanji candidates on the CRT screen. Below, it is also possible to input tertiary information and quaternary information of radicals in the same manner. However, input of tertiary information or higher information is performed by comparing the kanji table registered in the memory with the table corresponding to each radical information. Next, if it is not an additional input of radical information, proceed to step 3s, and check whether the input key was a selection key (“0” to “9”) from among the kanji candidates, and if not, proceed to step 3s. If so, it is assumed that the key input is invalid and the process returns to step 3n. If it is a kanji selection key, the selected kanji code is returned as input information to the program that issued the input request from the keyboard, and the process ends.

As described above, by determining and inputting the desired radical based on the reading of the radical or the number of strokes of the radical, and also inputting its constituent position information,
You can input kanji whose reading is unclear or whose shape is ambiguous. Therefore, not only when the reading of the radical is known in advance, but even when the reading of the radical is unknown, the desired radical can be easily input by inputting the number of strokes.
You can input kanji whose reading is unclear or whose shape is ambiguous. In addition, the selection of inputting radicals by reading or by number of strokes can be easily switched in the menu selection mode, improving the operability of inputting this type of kanji. I can do it.

As mentioned above, in this example, homophone radicals are distinguished by numbers, but it is also possible to add symbols such as A, B, etc., or use a special code corresponding to the radical. The service information and the registered data in the table should just be unified with any one of these.

〔Effect of the invention〕

As explained above, the present invention includes a first radical selection means for inputting reading information of radicals constituting a kanji and selecting and specifying one desired radical, and information on the number of strokes of radicals constituting a kanji. a second radical selection means for inputting and selecting and specifying one desired radical; and a selection for selecting and specifying either the first radical selection means or the second radical selection means. an input means for inputting desired information into one of the first radical selection means and the second radical selection means selected by the selection means;
A constituent position selection means for selecting and specifying which partial position of a desired kanji a desired radical constitutes, and a candidate specified by the correspondence between the radicals constituting a kanji and the constituent positions of the radical. a kanji table storing kanji information, a radical selected and designated by one of the first radical selection means and the second radical selection means, and the constituent position. To provide a kanji input device comprising kanji selection means for searching the table according to the constituent position of the radical selected by the selection means, displaying corresponding kanji candidates, and selecting a desired kanji. It is something.

Therefore, according to the present invention, when inputting a kanji, even if there is a kanji whose reading is unknown, it is possible to input one of the radicals that make up the kanji and the position that the radical makes up. Once you know the desired kanji, you can input the desired kanji by displaying the corresponding kanji candidates and selecting from among them.

Further, according to the present invention, when selecting and specifying a radical, the first radical selection means selects and specifies a desired radical from the pronunciation of the radical, and the first radical selection means selects and specifies the desired radical from the number of strokes of the radical. Because it has the first radical selection means, it is possible to easily select the desired radical by inputting the number of strokes, not only when the pronunciation of the radical is known in advance, but even when the pronunciation of the radical is unknown. can be entered. Furthermore, the choice of inputting a radical by its reading or by the number of strokes can be easily switched by the selection means, which improves the operability of input by the operator when inputting this type of kanji. I can do it.

Further, even if the shape of the kanji to be input is only vaguely known, it is possible to input the desired kanji if only the beginning of a part of the kanji and its constituent positions are known. Furthermore, there is no need to provide special keys on the keyboard to input configuration position information.

In addition, by selecting homophone radicals and additionally inputting radical information, the number of kanji candidates is reduced and the ease of input for the operator is improved.
