[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana input device for inputting a kana character and a Hangul character, which enables an operator to input characters more quickly using fewer keys.

[0002]

2. Description of the Related Art Kana characters are input using a keyboard, but there are many devices such as telephones for inputting only numerical values, and it is desired to use such devices to quickly input kana characters. I have. On the other hand, the number of buttons on a normal keyboard requires 50 or more buttons in a method of directly inputting 50 sounds, and 19 buttons (A, I, U, E, O of vowels and K of consonants) in Roman alphabet kana conversion. , G, S, Z, T,
D, N, H, B, P, M, Y, R, W) and several buttons for long sounds and the like.

Also, when inputting Hangul characters, the number of buttons is not enough on a normal keyboard, and the corresponding Hangul characters are input by looking at the consonant or vowel code table.
It is also possible to assign all possible consonants and vowels to keyboard buttons, but there are not enough buttons on keyboards on the market. That is, 19 consonants (primary), 10 vowels (middle), and 21 vowels when a compound vowel is added, consonants (final call called patchum)
Are defined as 27 keys, and a total of 67 key buttons are required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing the structure of the present invention.
Is a key group for the left hand, 120 is a key group for the right hand, and 1
Reference numeral 30 denotes a conversion dictionary storing conversion information, and 140 denotes a display device. 150 is a key button 11 operated by the operator.
Based on the information of 0, 120 and the contents of the conversion dictionary 130,
This is conversion means for displaying the conversion result on the display device 140.

FIG. 2 is an explanatory diagram of the conversion rules for kana characters. In the present invention, the kana character is converted by pressing the consonant key and the vowel key, and when the consonant is input with the right key so that the voiced sound can also be input with ten keys. , The vowel is input with the left key. For the voiced sound, the same consonant key is input twice to obtain the voiced sound input, and then the consonant key for which the corresponding vowel key is pressed. The input is made with the opposite key. In addition, a long key "-", a prompt "tsu", and the like are input by inputting a specific key twice.

FIG. 3 is an external view of a keyboard according to the first embodiment, in which numeric keys ("1" to "0") are arranged in a line and keys "1" to "5". Is operated with the left hand, and the keys "6" to "0" are operated with the right hand. 100 is a keyboard, 110 is a group of keys “1” to “5”, and 120 is a group of keys “6” to “0”. Reference numeral 111 denotes a key of a numerical value “1”, which is intended to be operated by a little finger, and reference numeral 112 denotes a key of a numerical value “2”, intended to be operated by a ring finger. Similarly, 113 is a numerical value “3”, 114 is a numerical value “4”, and 115 is a numerical value “5”.
, 121 is a numerical value “6”, 122 is a numerical value “7”,
123 corresponds to a numerical value “8”, 124 corresponds to a numerical value “9”, and 125 corresponds to a numerical value “0”. Which consonant for each key,
A label indicating whether a vowel is assigned is added. For example, the key 112 of the numerical value “2” is “K, i,
g, 2, ring finger ", which is assigned a consonant" ka (K) line "and a vowel" i (i) step ". 2
This indicates that “ga (g) line” is assigned as a dull sound when pressed once. "2" is the number 2
Are assigned, and “ring finger” indicates that it is better to operate with the ring finger.

The kana conversion rules of the present invention will be described with reference to FIGS. For example, when inputting “ki”, the left hand is used to first input the key “2” of the numeral “2” on the left side to indicate “ka line”, and then the right hand is used to enter the right side. By inputting the key 122 of the numeral “7” of “”, it is indicated that it is “step”, and the conversion device 150
Outputs “ki” to the display device 140. In the case of inputting "mi", the user first inputs the right-hand number "7" key 122 with the right hand and the left-hand number "2" key 112 with the right hand, contrary to the case of inputting "ki". Enter In this way, vowels are defined on both the left and right sides, and what is actually used is the reverse of the key of the consonant used first.

When "gi" is to be input, the key 112 of "2" on the left side is input, and the key 112 of "2" is input again because the sound is muddy. And
When the key 122 of the numeral “7” on the right side indicating “Dai” is input, the conversion device 150 outputs “Gi” to the display device 140. FIG. 4 is a modification of the key arrangement of FIG. 3. In FIG. 3, “A line” and “A column” are assigned to the key 111 of the numeral “1”. In the figure, “A line” and “A column” are assigned to the key 115 of the numeral “5”. The arrangement of FIG. 4 is more suitable for input with both hands.

FIG. 5 shows an embodiment in which the present invention is applied to a mobile phone, 300 is a mobile phone, and 340 is a display for displaying characters. 311, 312, 313, 31
4, 315, 321, 322, 323, 324, 325
Are numeric keys, respectively, and are used to enter kana. 326 and 316 are conversion keys,
It is a non-conversion key, and is a key for specifying whether or not to convert the input kana into kanji. FIG. 6 shows an example in which the present invention is applied to a numeric keypad, similarly to FIG.

FIGS. 7 and 8 relate to a second embodiment in which kana input is performed using five numeric keys. In FIG. 7, arrow keys are used to group numbers "1" to "5". By determining whether the key is a key or a key of a group of numbers "6" to "0", kana input is performed with five keys. In FIG. 8, the group is determined based on whether only one key is input or whether keys other than one key are input. That is, as shown in FIG. 17, when it is desired to input the pseudonym “ku”, the operator must first press the “ka row” key, and then press the “U” key. First, when pressing "A line" to "wa line", only the corresponding key needs to be pressed, and when pressing "na line" to "wa line", the corresponding key is excluded. Press four keys. Therefore, in this case, first, the key of the number "2" corresponding to "Ka row" is pressed, and then the four keys except the key of the number "3" corresponding to "U row" are pressed. .

FIG. 9 shows a third embodiment in which the present invention is applied to an apparatus having up, down, left and right direction instructions, and is applied to a keyboard for a game machine. The numeric keys shown in FIG. 19 are assigned to each direction of the direction instruction key 710, and the contents assigned to each direction of the direction instruction key 710 are changed by the keys 721 and 722.

FIG. 10 shows an example in which the present invention is applied to a mouse. Similar to FIG. 9, the numeric keys shown in FIG. 19 are assigned in the direction in which the mouse is operated. The left and right buttons of the mouse change the assignment in each direction. FIG. 11 relates to a fourth embodiment in which the present invention is applied to the input of Hangul characters, in which a consonant (Hatsune, Hoshi) and a vowel key of Hangul characters are assigned to a normal keyboard. is there. In the figure, A1 to A19 correspond to the first consonant, and B1 to B21.
Corresponds to a vowel and C3 to C27 correspond to a final consonant. The unassigned consonant endings are common to the consonant initials, and use the key of the consonant initials.

[First Embodiment] First, in the first embodiment, FIG. 3 showing an arrangement of a keyboard, FIG. 13 showing a data structure of a conversion dictionary, and FIG. 12 showing a processing flowchart of a conversion processing means will be described. Will be explained. In FIG. 12, first, the operator inputs a consonant corresponding to a kana to be input,
Then enter the vowel. The operator refers to the label attached to the keyboard and inputs a numeric key corresponding to the consonant of the corresponding kana. Then, the conversion processing means 150
Then, the entered numeric key is stored (step 11),
Then, using the numeric key, a search is made with reference to the conversion dictionary 130 to see if the corresponding kana is registered (step 12). However, in the present embodiment, as shown in the data structure of the conversion dictionary 130 in FIG. 13, since two or more numeric keys are used to convert to kana, only the first numeric key is input. If not, do not perform the actual search. As a result of the search, if there is a corresponding character (step 13), the character is displayed, and a numerical key input thereafter is set as a conversion target. That is, the storage area for storing the numerical keys to be converted is cleared (step S16).

As a result of the search, the corresponding character is found in the conversion dictionary 1
If not, it is determined whether the number of unconverted numeric keys is equal to or less than a predetermined number (step 14). In the present embodiment, since up to four numeric keys are to be converted, when the fifth unconverted numeric key is the fifth numeric key, it is taken out of the storage area storing the numeric keys input so far, Is displayed and the storage area storing the numerical keys is cleared, and the next input numerical key is set as a conversion target (step 15).

If it is determined in step 14 that the number of input numeric keys is three or less, the next numeric key input by the operator is stored (step 11). (Step 12). [Second Embodiment] In the second embodiment, the input of a pseudonym using ten numeric keys in the first embodiment is performed using five numeric keys and direction keys. It is.

FIG. 7 is an external view of the first keyboard of the second embodiment, FIG. 14 is a processing flowchart of the second embodiment, and FIG. 14 is a direction instruction conversion table of the second embodiment. FIG. 15 showing the data structure of
The first process of the second embodiment will be described with reference to FIG. 2 showing the Japanese syllabary conversion rule. For example, the kana "ku"
The case of inputting is described. According to the kana conversion rule of FIG. 2, the kana “ku” is “28” in the numerical data, and the numerical key “2” and the numerical key “8” are pressed. In this keyboard, as shown in the direction instruction conversion table of FIG. 15, the numerical values “1” to “5” operate the arrow keys 520 downward, and the numerical values “6” to “0” use the arrow keys. Operate 520 upward.

Therefore, the operator operates the numerical keys "2",
To press “8”, first, while operating the arrow key 520 downward, press the “2 or 7” key 512, and then, while operating the arrow key 520 upward,
A “3 or 8” key 513 is pressed. Then, the conversion processing unit 150 refers to the conversion dictionary 130 and displays the kana “ku” on the display device 140.

The operation of the conversion processing means 150 at this time will be described. First, the operation of the arrow keys 520, which is the mode designation input by the operator, and the input of the numerical keys are stored (step 21). Then, with this mode designation and numerical keys, the corresponding numerical data is obtained by referring to the direction instruction conversion table of FIG. 15 and stored in a predetermined area (step 2).
2). Then, using the stored numerical data, the kana conversion dictionary 130 is searched (step 23). If there is a corresponding character, it is output to the display device 140, and the area storing the numerical data is cleared to prepare for the next input (step 27).

As a result of searching the kana conversion dictionary, if there is no corresponding character, it is determined whether the number of unconverted numerical data stored in the area is equal to or larger than a predetermined value (step 25). In the present embodiment, since up to four numerical data are to be converted, when the numerical data is four or more, the unconverted numerical data that has been input is output to the display device 140 without conversion (step 26). . If the number is three or less, the input of the next numeric key is accepted.

Subsequently, in the second embodiment, the mode is designated by using the arrow key 520 of the first embodiment, and determining whether the key input is one or all except one. Is determined. FIG. 8 showing an external view of a second keyboard of the second embodiment, FIG. 16 showing a processing flowchart in the second embodiment 2;
Referring to FIG. 17 illustrating the operation of the second embodiment, part 2,
The second process of the second embodiment will be described.

FIG. 17 illustrates a case in which the pseudonym "ku" is input, as in the description of the first embodiment. The operator first presses the key “612” of “2 or 7” corresponding to the numerical value “2”, and then all keys (611) except the key 613 of “3 or 8” corresponding to the numerical value “8” , 612, 614, 615). Then, the conversion processing means 150 determines that the numerical value “2” has been input first, and then has input the numerical value “8”, and outputs the kana “ku” to the display device 140.

The processing of the conversion processing means 150 in FIG. 16 will be described. First, it is determined whether the operator has input only one key (step 30). If only one key is pressed, the numerical data of the first mode corresponding to that key is stored (step 31). When the key “2 or 7” is pressed, the first “2” is stored.

Next, when a plurality of keys are pressed, it is determined whether all but one key are pressed (step 32). In that case, the second mode corresponding to the key not pressed is determined. (Step 3)
3). When the “3 or 8” key is pressed, the subsequent “8” is stored. If there are a plurality of keys that have not been pressed in step 32, the entered one is invalidated (step 34).

The subsequent processing is the same as in the first and second embodiments, and the kana conversion dictionary 130 is searched using the stored numerical data (step 35). . If there is a corresponding character, display it on display device 1.
The numerical value data is output to the area 40, and the area storing the numerical data is cleared to prepare for the next input (step 39). As a result of searching the kana conversion dictionary, if there is no corresponding character, it is determined whether the number of unconverted numerical data stored in the area is equal to or larger than a predetermined value (step 37). In the present embodiment, up to four pieces of numerical data are to be converted, and if there are four or more pieces of data, the unconverted numerical data that has been input is output to the display device 140 without conversion (step 3).
8). If the number is three or less, the input of the next numeric key is accepted.

[Third Embodiment] The third embodiment differs from the first embodiment in that kana is input using five numeric keys in the first embodiment. Movement in a predetermined direction) FIG. 9 showing an external view of the first keyboard of the third embodiment, FIG. 18 showing a processing flowchart in the third embodiment, and direction designation conversion in the third embodiment 1 The first process of the third embodiment will be described with reference to FIG. 19 showing the data structure of a table.

Third Embodiment A keyboard of the first embodiment is a keyboard of a game machine.
There are a total of five patterns, including the case where there are direction indications of down, left, and right, and further no direction is indicated. Furthermore, it has two keys, an A button and a B button. Ten patterns can be identified by the five direction instruction patterns and the two A and B buttons.

The conversion into numerical data will be described using the data structure of the direction designation conversion table 731 in FIG. For example, when the upward instruction of the direction instruction key 710 and the A button 721 are pressed, the numerical value is “1”. When only the A button is pressed without operating the direction instruction key 710, the numerical value becomes “3”. The processing of the conversion processing unit 150 in the third embodiment will be described with reference to FIG. Direction-++ and A, operated by the operator
The input of the B button is stored (step 41), and using the key as a key, the direction indication conversion table of FIG. 19 is searched to find the corresponding numerical data (step 42).

Then, using this numerical data, a conversion dictionary is searched (step 43). If there is a corresponding character, it is output to the display device 140, and the area storing the numerical data is cleared to prepare for the next input (step 47). As a result of searching the kana conversion dictionary, if there is no corresponding character, it is determined whether the number of unconverted numerical data stored in the next area is equal to or greater than a predetermined value (step 45).
In this embodiment, since up to four numerical data are to be converted, if the number is five or more, the unconverted numerical data that has been input is output to the display device 140 without conversion (step 46). . If the number is four or less, the input of the next numeric key is accepted.

The third embodiment 2 is composed of a directional key 71
A mouse operation is used instead of 0, and left and right buttons are used for the mouse instead of the A and B buttons of the first embodiment. Labels are added above the left and right buttons of the mouse as shown in FIG. 10 above the left and right buttons of the mouse so that the operator can easily understand which key the combination of the direction and the right and left buttons corresponds to. . Third Embodiment 1 and 2
In both cases, the key guide shown in FIG. 21 is displayed on the display so that the operator can easily understand the assignment of the combination of the direction and the button.

The operator gives a direction instruction using a mouse while pressing any of the left and right buttons. The conversion processing means is based on the difference between the position information specified by the mouse at the time when the left and right buttons are pressed and the time when the mouse is released, and
Left, determine the middle. Subsequent processing is the same as in the first embodiment. [Fourth Embodiment] In the fourth embodiment, the kana input of the first embodiment is applied to Hangul character input, and the keyboard used is generally used as shown in FIG. It is the same as a keyboard. FIG. 11 shows a conventional keyboard in which consonants of Korean characters (initial voice, final voice) and vowel keys are assigned. In the figure, A1 to A
19 corresponds to the first consonant, B1 to B21 correspond to the vowel, and C3 to C27 correspond to the final consonant. The unassigned consonant endings are common to the consonant initials, and use the key of the consonant initials.

The Hangul character is similar to the Japanese kana, and a consonant and a vowel can represent one character. There is a consonant first, then a vowel, followed by a consonant final. However, consonants may or may not end.
It is not possible to assign all consonants to a key for each of the initial and final voices due to the limitation of the number of keys. Therefore, in the present invention, a vowel is assigned to both the left and right key groups, and when a vowel belonging to the same key group as the key group to which the key of the initial voice of the consonant belongs is pressed, the final voice of the consonant continues. In the case where a vowel belonging to another key group is pressed down from a key group to which the key which has pressed the initial voice of the consonant is pressed, it is determined that the consonant ending does not continue.

For example, as shown in the record on the second line in FIG. 23, the letter "S" belonging to the key group on the left hand is pressed, and the letter "N" belonging to the key group on the right is pressed subsequently. Then, the conversion processing means 150 outputs the corresponding Hangul character to the display device 140 based on the key input so far, assuming that the consonant ending does not follow thereafter. Further, as shown in the record on the fourth line, when the alphabetic letter “S” belonging to the left-hand key group is pressed, and then the alphabetical letter “B” belonging to the same left-hand key group is pressed, the conversion processing is performed. Means 1
30 treats the next input of the consonant as the end of the consonant, assuming that the end of the next consonant continues.

[0035]

According to the present invention, kana characters can be input with a smaller number of strokes on a keyboard having only a few keys. In addition, Hangul characters, which have been input consonants and vowels with a two-digit code, have half the number of strokes because of the keys for consonants and vowels, and can be input quickly.
