However, for example, a dictionary display device disclosed in Japanese Patent Laid-Open No. 2-165274 is disclosed.
When applied to a device equipped with a large vocabulary dictionary in which the number of words corresponding to the headword becomes very large, it is difficult to move the scroll bar to the vicinity of the word to be searched for with the headword, so it is necessary to get used to scroll bar operation. Therefore, there is a problem that the word search efficiency is reduced.

In Japanese Patent Application Laid-Open No. Hei 7-230463, a headword group is subdivided to some extent and the number of display words increases, so that an enlarged display control function is required. Therefore, a display device having a high-precision screen is required, and there is a problem that the cost of the display device is increased.

For example, each of the devices described in JP-A-2-165274 and JP-A-7-230463 is used.
When the present invention is applied not only to a dictionary search but also to a character input device for selecting and inputting a desired word from a dictionary, the following problems occur. That is, when words are continuously input, it is not always better to search from the headword at the top, and if the data corresponding to the headword has a multi-step configuration, the headword at the appropriate stage is used. Searching by words may be more efficient. This cannot be realized with the former device. Even with the latter device, there is a problem that the search for a headword must always be performed accurately. Further, in the above-mentioned conventional apparatus, since a learning function capable of preferentially inputting a word once selected is not added, the efficiency of character input cannot be increased.

The present invention has been made in view of the above circumstances, and uses, for example, a word table storing notations of words and their readings, and a heading table storing readings and headings. Provided are a character input device and method capable of inputting characters with a reduced number of searches, and a medium storing a character input device control program.

The data is read out to the buffer 8 (step S3802). Subsequently, the contents of the display buffer 8 are displayed on the initial screen (search screen) (step S380).
3).

Thereafter, a key input wait state is set (step S3804). For example, the types of key input include four directions of the cross key (1a, 1b, 2a, 2b) shown in FIG. 36 and two buttons 1c and 3a shown in FIG. No).

The cross keys 1a and 1b and the button 1c function as the screen switching instruction unit 1, the cross keys 2a and 2b function as the scroll instruction unit 2, and the button 3a functions as the confirmation instruction unit 3. If an instruction to end the search process has been input (step S3805), the process ends. If not, the process for each of the other input keys is activated (step S38).
06), returning to the process of step S3804.

Next, the processing procedure for each input key will be described. FIG. 39 is a flowchart showing the procedure of the process (2) according to the present embodiment. FIG. 39 shows a case where an upward direction instruction is input from the cross key of the scroll instruction unit 2. This input is made in the heading table 11, the first / second word tables 9, 10 or the auxiliary character table 13,
This is an instruction to scroll the display data of the target location upward.

Therefore, it is determined whether or not the display data of the currently displayed target portion is the first data (step S).
3901), if it is the head data, the display data of the target portion is moved to the end (step S3903), and if not, the immediately preceding display data is set as the display data of the new target portion (step S3902). Next, in order to display the display data of the new target portion at the center of the display screen, the display data before and after the display data of the required target portion according to the display range is read out to the display buffer 8 (step S390).
4) The display data of the display buffer 8 is displayed again on the screen (step S3905).

FIG. 40 is a flowchart showing the procedure of the process (3) according to this embodiment. FIG. 40 shows a case where a downward instruction is input from the cross key of the scroll instruction unit 2. This input is an instruction to scroll the display data of the target portion downward in the heading table, the first / second word table, or the auxiliary character table.

Therefore, it is determined whether or not the display data of the currently displayed target portion is the end data (step S4001), and if it is the last, the display data of the target portion is moved to the beginning (step S4003). Otherwise, the display data immediately after is set as the display data of the new target portion (step S4002). Next, in order to display the new target portion at the center of the display section, data before and after the necessary target portion according to the display range is read out to the display buffer 8 (step 4004), and the display data of the display buffer 8 is redisplayed on the screen. (Step 4005).

FIG. 41 is a flowchart showing the procedure of the process (4) according to this embodiment. FIG. 41 shows a case where a rightward instruction is input from the cross key of the screen switching instruction unit 1. This input is performed by “first heading display data” → “second heading display data” → “third heading display data” → “first heading display data”.
In the direction of "word display data" → "second word display data", or while displaying auxiliary character display data,
The screen is switched from higher-order data to lower-order data such as “first auxiliary character display data” → “second auxiliary character display data”.

First, it is checked whether the data being displayed is the lowest data (second word display data, second supplementary character display data, etc.) (step S4101). , The process is terminated because it cannot be moved downward. If not, the lower data is read (step S4102), and the position of the lower data corresponding to the currently displayed target portion is detected (step 4103).

For example, when switching from the third heading display data to the word display data, for the display data of the target portion in the third heading table, a pointer to lower data shown at 45 in FIG. The displayed word display data becomes the word display data of the new target portion. This is the same when switching screens between other data.

After the display data of the target location is detected, the display data before and after the display data of the target location required according to the display range is displayed in order to display the display data of the new target location at the center of the display screen. Is read out to the display buffer 8 (step S4104), and the display data of the display buffer 8 is displayed again on the screen (step S4105).

FIG. 42 is a flowchart showing the procedure of the process (5) according to this embodiment. FIG. 42 shows a case where a left direction instruction is input by the cross key of the screen switching instruction unit 1. This input is performed in the direction of “second word display data” → “first word display data” → “third heading display data” → “second heading display data” → “first heading display data”, or an auxiliary character. If the display data is being displayed, the screen is switched from lower data to higher data, such as “second auxiliary character display data” → “first auxiliary character display data”.

First, it is checked whether the data currently being displayed is the highest data (first heading display data or first supplementary character display data) (step S4201). Since the upward movement cannot be performed, the processing is completed. If not, the upper data is read (step S4202), and the position of the upper data corresponding to the currently displayed target portion is detected (step S420).
4203).

For example, in switching from the word display data to the third heading display data, for the display data of the target portion in the word display table, a pointer to the upper data shown at 54 in FIG. 5 is taken out and corresponds to the pointer. The third heading display data becomes the display data of the new target portion. This is the same when switching screens between other data. After detecting the display data of the target location,
In order to display the display data of the new target portion in the center portion of the display screen, the data before and after the necessary target portion is read out to the display buffer 8 according to the display range (step S4204).
The display data of the display buffer 8 is displayed again on the screen (step S4105).

FIG. 43 is a flowchart showing the procedure of the process (6) according to this embodiment. FIG. 43 shows a case where a screen switching instruction is input by the button 1c of the screen switching instruction unit 1.

4401).

In the case of the body data group, the first
It is checked whether the data is heading display data (step S440).
2). If it is the first heading display data, the process ends because there is no selectable notation character string. If not, it is next checked whether the data is the second and third heading display data (step S4403). If the data is the second or third heading display data, the learning unit 14 checks whether the learning notation stored in the learning area (for example, see 46 in FIG. 4) is displayed (step S440).
4) If there is, take out the learning notation (step S44)
05), and store it at the end of the input buffer 22 (step S4406).

In step S4403, the second and third
If it is not the heading display data, it is the word display data or the second word display data, and therefore, there is a selectable notation character string in any case, and these notation character strings are extracted (step S4407). Next, the example search unit 20 starts an example search process (step S4408).
Then, the extracted notation character string is stored at the end of the input buffer 22 (step S4409).

Next, the co-occurrence search unit 17 starts a co-occurrence search process (step S4410). Further, when a notation character string is selected in step S4405 and step S4409, the selected notation character string is stored in the learning buffer 15 in the learning unit 14 as learning data (step 4411).

Then, the learning section 14 follows a pointer (54 in FIG. 5) to the higher-level data corresponding to the word display data of the determined notation (step 4412), and displays the third heading display data and the second heading display data. The learning notation is stored in each of the learning notation areas (see 46 in FIG. 4 and 36 in FIG. 3) (step S4413). Step S44
In 01, if the data being displayed is an auxiliary character data group, the notation character string as the target portion is selected and taken out as being confirmed (step S441).
4), and store it at the end of the input buffer 22 (step S4415).

FIG. 45 is a flowchart showing the procedure of the process (8) according to this embodiment. FIG. 45 shows an example search process which is a subroutine of step S4408 in FIG. The example search unit 20 checks the learning buffer 15 to determine whether there is a previously confirmed notation (step S450).
1) If not, end the process. If there is a confirmed notation last time, the confirmed notation is taken out (step S4502), and then the notation is a word determined from the word display data or is determined from the auxiliary character display data. It is checked whether the character string is accompanied by a character string (step S4503).

If the word consists only of the determined words from the word display data, there is a possibility that the case information can be complemented with the newly determined words.
Then, the process proceeds to the example search process, and if not, the process ends. Example data is searched based on the previously determined word and the newly determined word (step S4504), and if there is matching example data (step 450)
5) The case information is taken out from the example table (352 in FIG. 35), connected to the newly determined notation character string, and input to the input buffer 22 (step S4506).

FIG. 46 is a flowchart showing the procedure of the process (9) according to this embodiment. FIG. 46 shows a co-occurrence search process which is a subroutine of step 4410 in FIG. First, the co-occurrence table 16 is searched based on the newly determined word (step 4601). Co-occurrence table 1
6, if there is co-occurrence data that matches the previously determined word (step S4602), the notation data having a co-occurrence relationship with the co-occurrence data is extracted (step S460).
3).

Next, the retrieved word data is searched in the first word table 9 to detect the stored position (step 4604). Then, the pointer to the higher-order data of the searched word display data is traced, and the positions of the corresponding third and second display data are detected (step S46).
05), the co-occurring notation extracted earlier is stored in the learning notation area (step S4606). As described above, until there is an instruction to end the processing (step S380 in FIG. 38).
5) The above process is repeated according to the input key.
