BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input device, and more particularly to a character input device that is used in a word processor or the like and mainly converts an input kana character string into a character string containing kana and kanji.

0002

BACKGROUND OF THE INVENTION In a general word processor, when a person inputs a kana key input (without Roman character conversion) inputting a sentence containing alphanumeric characters, kana, and kanji, the process is as follows. As an example, consider inputting the sentence "RICOH Co., Ltd.". a) First, switch to kana mode (if it's not already there). b) Press the keys “ka”, “fu”, “”, “shi”, “ki”, “ka”, “”, “i”, “shi” and “ya”. c) Set to alphanumeric mode. d) Press the keys ``R'', ``I'', ``C'', ``O'', and ``H''. e) Switch to medium mode again. f) Press the key “ha”. g) Press the conversion key to convert it to "RICOH Co., Ltd.".

[0003] In this way, when inputting a sentence containing alphanumeric characters, kana, and kanji, it is necessary to switch between the kana mode and the alphanumeric mode each time. As described above, in the conventional technology, when a user who does not input Romaji inputs a sentence containing alphanumeric characters and kana characters, the user has to frequently switch between the alphanumeric mode and the kana mode. Also, I forgot to switch the mode, and when I should have typed ``RICOH'', I was in Kana mode and instead typed ``Sunisoraku'' by mistake.

FIG. 1 is a block diagram for explaining an embodiment of a character input device according to the present invention. In the figure, 1 is a character string input means, 2 is a first character string conversion means, and 3 is a character string. a group generation means; 4 a second character string conversion means; 5 a character string display means;
6 is a character string selection means, and 7 is a character string output means. Each character of the first character string inputted by the user using the character string input means 1 from the keyboard is converted into a second character string by the first character string conversion means 2. The character string group generation means 3 combines each character of these two character strings to generate a plurality of third character strings consisting of possible combinations. The plurality of third character strings generated by the character string group generation means 3 are converted into a plurality of fourth character strings by the second character string conversion means 4, and are displayed on the screen by the character string display means 5. are displayed, and one of them is selected by the user using the character string selection means 6. The selected character string is output to the screen or other application software by the character string output means 7.

FIG. 2 is a flow chart for explaining the operation of the character input device according to the present invention. Below, each step will be explained in order. In the embodiment of the present invention, a case will be described in which the character string "RICOH" is input. step 1; Input a character string from the keyboard. At this time, if the user is in the kana key mode, the character string "Sunisorakuha" is input instead of "RICOHwa". Step 2: Each character of the character string is converted according to Table 1 shown in FIG. Table 1 is a table in which correspondence is established for each character input by the same key on the keyboard. "Character 1" is assigned an alphanumeric character, and "Character 2" is assigned a corresponding kana. By modifying this table, it is possible to support keyboards with other layouts. Here, since a kana is input, Table 1 is looked up using "Character 2" to convert it to "Character 1". Therefore, “su” → “
"R", "ni" → "I", etc., resulting in the character string "RICOHF".

Step 3: Next, the results of the combinations are registered in table 2. That is, the two character strings "Sunisorakuha" and "RICOHF" are combined to generate a plurality of new character strings. The generated character string is stored in table 2 shown in FIG. Step 4: Perform kana-kanji conversion for each character string stored in table 2. For example, "Sunisorakuha"
``Sunisorakuha''``Sunisorakuha'' ``Vinegar ni sky ward wa''
...is converted. At this time, it is assumed that these candidates are given points according to their certainty. Step 5: After converting all the character strings in the table 2, the obtained candidates are registered in the table 3 shown in FIG. 5, excluding those with low scores. Step 6: The candidates in Table 3 are presented to the user, and the user selects one of them. Selection is made using a mouse, cursor keys, number keys, etc. At this time, the user selects the character string "RICOH wa" from among the candidates. Step 7: Output the selected character string to the screen or other application software. In this way, it is possible to correctly input a character string containing alphanumeric characters and kana characters without having to switch between kana mode and alphabetic character mode.

According to the embodiments described above, it is possible to obtain the conversion rule desired by the user without changing the mode in kana-kanji conversion. By dividing the conversion into two stages in this way, we were able to absorb the difference in modes and obtain candidates that included the desired conversion results even if we forgot to switch modes. However, as in the example of "RICOH", a large number of candidates are obtained, such as "R to CO ward", "Vinegar to empty ward", etc., and it is extremely difficult to find the correct answer from these many candidates. It can be difficult. In such a case, it is preferable to use the embodiments described below.

FIG. 6 is a block diagram for explaining another embodiment of the character input device according to the present invention, in which 11 is a character string input means, 12 is a first character string conversion means, and 13 is a character string input means. 14 is a second character string conversion means, 15 is a grouping processing means, 16 is a character string display means, 17 is a character string selection means, and 18 is a character string output means. Each character of the first character string input by the user from the keyboard using the character string input means 11 is converted into a second character string by the first character string conversion means 12. The character string group generation means 13 is
The characters of these two character strings are combined to generate a plurality of third character strings consisting of possible combinations. The plurality of third character strings generated by the character string group generation means 13 are converted into the plurality of fourth character strings by the second character string conversion means 14.
are converted into character strings, and grouped by the grouping processing means 15 based on their characteristics. The grouped character string candidates are displayed in groups on a terminal etc. by the character string display means 16, and one of them is selected by the user by the character string selection means 17. The selected character string is output to the screen or other application software by the character string output means 18.

FIG. 7 is a flow chart for explaining the operation of the character input device shown in FIG. Below, each step will be explained in order. In addition, in the embodiment of the present invention, “
A case where the character string "RICOH" is input will be explained. step 1; Input a character string from the keyboard. At this time, if the user is in the kana key mode, the character string "Sunisorakuha" is input instead of "RICOHwa". Step 2: Each character of the character string is converted according to Table 1 shown in FIG. Table 1 is a table in which correspondence is established for each character input by the same key on the keyboard. "Character 1" is assigned an alphanumeric character, and "Character 2" is assigned a corresponding kana. By modifying this table, it is possible to support keyboards with other layouts. Here, since a kana is input, Table 1 is looked up using "Character 2" to convert it to "Character 1". Therefore, “su” → “
"R", "ni" → "I", etc., resulting in the character string "RICOHF".

Step 3: Next, the result of the combination is registered in table 2. That is, the two character strings "Sunisorakuha" and "RICOHF" are combined to generate a plurality of new character strings. The generated character string is stored in table 2 shown in FIG. Step 4: Perform kana-kanji conversion for each character string stored in table 2. For example, "Sunisorakuha"
``Sunisorakuha''``Sunisorakuha'' ``Vinegar ni sky ward wa''
...is converted. At this time, attributes are given to these candidates according to the character strings from which they are based. For example, the following ■
Do like ~■. ■ Let the two character strings "RICOHF" and "Sunisorakuha" be a and b, respectively. ■Regarding the original characters, "RICOH" becomes "aaaaab". Also, "Suni CO KUHA" becomes "bbaabb". ■ Count the number that changes from "a" to "b" and the number that changes from "b" to "a". For example, “aaa
aab" becomes 1, and "bbaabb" becomes 2. Further, "aaaaaa" is 0. (2) The obtained number of change points is used as the attribute of the candidate.

Step 5: After converting all the character strings in Table 2, for the obtained candidates,
The candidates are grouped based on their attributes and registered in Table 4 shown in FIG. Step 6: The user presents the candidates in Table 4 for each group. An example of the screen at this time is shown in FIG. here,
The user selects one of the candidates and selects "RICOH"
Select the string. Step 7: Output the selected character string to the screen or other application software. In this way, it is possible to more quickly and correctly input a character string containing alphanumeric characters and kana characters without having to switch between the kana mode and the alphabetic character mode.
