Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key input device. Specifically, the present invention relates to a key input device capable of efficiently inputting characters.

[0002]

2. Description of the Related Art In recent years, mobile phones have become highly functional so that they can send and receive e-mails, browse the Internet, etc., as well as make phone calls. In a small device such as this mobile phone, as many as 80 keys cannot be arranged like a keyboard. Therefore, for example, in a mobile phone,
Set the numbers, kana characters, and letters on the 12 keys provided for entering the telephone number, and press the mode keys to switch the input mode in sequence. While watching the mode display on the screen, you can enter the number input mode and kana input mode. , Switch to alphabet input mode and input numbers and characters.

For example, in a conventional mobile phone, in order to input Japanese (Hiragana), the numbers for "1" to "0" are input to the "A" line, "KA" line, and "SA" line. , ...
The characters were set in the Japanese syllabary arrangement, such as the "Ra" line and "Waon". Then, for example, with the key set in the "A" line, 1
"A" is input when you press it twice, "I" when you press it twice, "U" when you press it three times, "E" when you press it four times, and "O" when you press it five times. It had been. Similarly, by pressing the other keys 1 to 5 times, each Japanese character (kana) was input.

The arrangement of character input in such a mobile phone has already been widely used, and is used by many people.

[0005]

However, in such a conventional character arrangement, in order to input a kana character, the key must be pressed up to five times, which complicates the input operation and speeds up character input. There was a problem that it could not be realized. In particular, since the number of times the key is pressed is set regardless of the frequency of occurrence of the characters, it is necessary to press the key approximately 3 to 4 times on average when inputting multiple characters by kana input.
The operation was complicated.

On the other hand, in recent years, various input methods have been proposed in order to enable more efficient character input in a key input device having a small number of keys. However, the arrangement of character input in mobile phones is already widely used, and if a new input method is adopted instead of such conventional character input, users will be confused and reluctant to use it. There was a problem that it did not spread.
Such a problem is not limited to a mobile phone, and is the same when a character is input by a normal desk phone, a FAX, or the like. The same problem arises not only when using a telephone but also when inputting characters using a wristwatch, a calculator, an electronic notebook, a portable personal computer, a PDA (personal digital assistant), a ten-keyboard connected to a personal computer, or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a key input device which can reduce the number of times a key is pressed at the time of character input to simplify the input operation, and which can be easily remembered and typed and which can be used without a feeling of resistance. .

[0008]

The key input device of the present invention will be described with reference to the drawings. At least twelve main keys 21 to 32 in four rows of upper and lower rows and three columns of left and right rows are provided. On the main keys 21 to 32, the numbers "1,
2,3,4,5,6,7,8,9,0 "and symbols" *, # "are respectively set, and 10 main keys 21 to 21 out of these 12 main keys 21 to 32 are set. Two
The kana characters "a, ka, sa, ta, na, ha
Well, la, wa "are set respectively, and the vowels for vowels are set respectively in the five main keys 21 to 25 of the six main keys 21 to 26 in the upper two steps. 5 out of the 6 main keys 27 to 32 on the second side
Keys 21 to 29 and 31 to which the vowels for dakuon are set and kana characters are set to the individual main keys 27 to 31 respectively.
After pressing, the keys 21 and 2 for which the vowels for clearing are set
When 5 is pressed, in the line indicated by the kana character of the keys 21 to 29, 31 in which this kana character is set, the kana of the syllabary of the stage indicated by the vowel of the key 21 to 25 in which the vowel for the kana is set Keys 21-2 with characters entered and kana characters set
When the keys 27 to 31 to which the vowels for dakuon are set are pressed after the keys 9 and 31 are pressed, in the line indicated by the kana characters of the keys 21 to 29 and 31 in which this kana character is set, It is characterized in that the kana characters of the dakuon of the stage indicated by the vowel of the keys 27 to 31 in which the vowel for the dakune is set are input.

Here, Kiyone means the kana character "ka, sa,
"Ta, na," means each syllable in the line indicated by "Ma, Ya, La, Wa". Also, the dakuon is a kana character "ga, za, da, ba".
Is each syllable in the line indicated by.

According to the present invention, the frequently used vowel "a"
(In the present invention, vowels are written in alphabets that represent vowels in Roman alphabet input.
Is. The same applies to the following vowels) "," i
"I", "u", "e", "o"
Are set to different main keys, and the kana characters “ka, sa, ta, na, ha, ma, ya, ra” are set to different main keys. Only two keystrokes, such as pressing a key with Kana characters set as the keystroke, and then pressing either the key with the vowel for the clear sound or the key with the vowel for the voiced sound as the second keystroke. You can easily enter Kana characters.

That is, in the case of combining with a vowel for a pure sound, each kana character is added to each line (or line, sa line, ta line, na line,
Is a consonant (K, S,) indicating a line, a line, a line, a line, a line
(T, N, H, M, Y, R, W), and Kana characters can be input by the same operation as the Roman character input combined with vowels. When combining with a vowel for voiced sound, each kana character is regarded as a consonant (G, Z, D, B) indicating each line (a line, a line, a line, and a line), and a Roman character input to be combined with the vowel is input. You can enter Kana characters by the same operation as.
Therefore, as compared with the conventional key input device, the number of keystrokes at the time of character input can be reduced, the input operation can be simplified, and the kana character can be input very efficiently.

Here, in general, when a kana sound kana character is input, it is performed by pressing the dakuten "" key after the kana sound kana character is input. Compared with this, the number of keystrokes increases. On the other hand, in the present invention, two keys for inputting a vowel, a key with a vowel for a clean voice and a key with a vowel for a vocal sound, are provided, and only a vowel for a vocal sound is input instead of the vowel for a clean voice. Since it is possible to input a kana sound kana character, the number of keystrokes can be made the same for the clear sound and the dakuon sound, and the number of keystrokes can be reduced as compared with the conventional case, and the input operation can be easily performed.
Therefore, the text input speed can be effectively improved.

Furthermore, since the same kana characters as those of the conventional key input device are set in the 12 main keys, the conventional key input device is provided with the input mode corresponding to the present invention. The input device can be used as it is.
Therefore, since the user is familiar with the key arrangement, he / she can easily grasp the input operation, and can comfortably operate while suppressing the resistance feeling during use. At this time, it is preferable that the key input device of the present invention is configured so that the existing input method and the new input method of the present invention can be used together. In this way, since the existing input method and the new input method can be freely selected and used, the new input method can be used easily and the use thereof can be promoted.

Further, the manufacturer of the key input device does not need to separately manufacture the one adopting the existing input method and the one adopting the new input method, and the key having only the new input method is high in risk. Since it is not necessary to manufacture and sell the input device, it can be manufactured and sold easily.

Here, each vowel "a,
i, u, e, o ”is the same vowel“ a,
It is preferable that keys i to u are set to keys 27 to 31 which are two steps lower than keys 21 to 25 in which "i, u, e, o" are set. With this arrangement, the arrangement of the respective vowels for the clear sound in the upper two rows and the arrangement of the respective vowels for the dull sound in the lower two rows are different from each other only in the vertical position, and are relatively the same. Kana character input can be operated in the same way as Kiyone's Kana character input,
Easy to get used to.

In addition, the three main keys of the first stage are
In order from the left key, "a", which is a vowel for a pure sound,
"I" and "u" are set respectively, and the two main keys from the left side of the second row are set to the vowels for vowels "e" and "o" in order from the left side key, For the three main keys in the third row, the vowels “d”, “i”, and “u” for the voiced sound are set in order from the left key,
It is preferable that “e” and “o”, which are vowels for dakuon, are set in order from the left key to the two main keys from the left side of the fourth row.

In this way, the vowels "a", "i", "u", "e", and "o" for the clean and dull sounds are respectively from the first stage to the second stage or the second stage. 3rd to 4th
Since it is set in the order from the left to the right, the key position of each vowel is easy to remember, and the input speed can be improved.

Of the six main keys in the upper two rows,
A main key (for example, the key 26 in the right column of the second row) to which a vowel for a clean voice is not set has a function of confirming the input of a single vowel, and at least a vowel for a clean voice "i, u,"
If any of the keys 22 to 25 in which any one of "e, o" is set is pressed and then the key 26 having the function of confirming the input of the single vowel is pressed, the vowel for the vowel "i, u" ,
It is preferable that “e, o” is input alone.

Kana characters are also set in the keys 22 to 25 to which the vowels "i, u, e, o" for vowels are set. Therefore, if the key is pressed only once, the kana characters are input. I can't judge if it's a vowel input for a pure sound. Therefore, according to the present invention, it is possible to perform only two keystroke operations such as pressing a key for which a vowel for a clear sound is set as the first keystroke and then pressing a vowel confirmation key as the second keystroke.
Each vowel "i, u, e, o (i, u, e, o)" can be fixedly input as a single vowel. Therefore, compared to the existing input method, the number of keystrokes is the same when inputting a single vowel "i", but the number of keystrokes can be reduced when inputting a single vowel "u, e, o (u, e, o)". , Input speed can be improved.

Here, the key for which the vowel for the clear voice is set is
Since it is frequently used in text input, the user naturally remembers the positions of these vowels for vowels. For this reason, when inputting a single vowel, the finger tends to momentarily move to the position of the key in which the clear vowel indicating the vowel to be input is set. Therefore, in the present invention,
Since the single vowels are input in the order of the keys with the clear vowels "i, u, e, o" and the single vowel confirmation function key, compared to the case of inputting the single vowels in the reverse order, According to the reflexive movement of the finger, a single vowel can be quickly input, and an input error due to the reflexive movement of the finger can be prevented, so that the input operation can be efficiently performed.

The key 21 for which the vowel for cleansing "a" is set may be operated in the same procedure to input the single vowel "a", but the kana character "a" is entered.
And the vowel for vowel "a" are usually set to the same key. In this case, since it is not necessary to distinguish between kana and vowels, the key for which the vowel for vowel "a" is set is independent. When pressed with, the single vowel "a" can be confirmed. In this case, since the single vowel "a" needs to be input only once by pressing the key 21, the operability can be further improved.

Here, the kana character "a, ka, sa, ta,
It is preferable that a consonant sound and a long sound are set to one of the two main keys 30 and 32 other than the ten main keys to which “Namaha, Ma, Ra, Wa” is set. In such a configuration, for example, if the main key 30 in which the consonant and long tone are set is pressed once, the consonant “t” is input, and if the key is continuously pressed again, the long consonant “-” is input. Long and consonant sounds can be input with one or two keystrokes. Therefore, in consideration of the fact that the general existing input method requires about four keystrokes to input a consonant "tsu", and at least about three keystrokes to input a long sound "-". Compared to the input method of, the number of keystrokes at the time of inputting a consonant and a long tone can be reduced, and the input speed can be improved.

Furthermore, the kana character "a, ka, sa, ta, na,
The other key 32 of the two main keys 30 and 32 other than the ten main keys to which “Ha, ya, ra, wa” are respectively set is used for inputting a syllabary in Romaji input. It is preferable that “y” is set. Here, for example, there are “Kya”, “Ju”, “Cho”, etc., that is, after a part of the consonants showing the “I” stage, a half vowel “Ya, Ju, "
Will continue.

In such a structure, for example, after pressing a key in which kana characters are set as the first keystroke,
As the second keystroke, press the key 32 in which "y" is set, and then as the third keystroke, press the key in which the vowels for the pure sound are set or the key in which the vowels for the voiced sound are set,
If the tapping sound is input, the tapping sound can be input by three keystroke operations.

Therefore, in the general existing input method,
Considering that it requires two keystrokes to input the "i" consonant and two to six keystrokes to input the half vowel "ya, yu, yo". (6 on average
Times) is required. Therefore, compared to the existing input method, the number of keystrokes at the time of inputting a jumble can be reduced, and the input speed can be improved.

Also, after the key 32 for which "y" has been set is pressed, the key 22 for which the vowel "i" for cleansing has been set.
When is pressed, one of “yuu (“ yuu ”or“ yu ”)” or “you (“ you ”or“ kyo ”)” is input and the key 32 to which “y” is set is input. After the key is pressed, when the key 24 to which the vowel for cleansing "e" is set is pressed, it is preferable to input the other of "yuu" or "you".

Further, after the key 32 for which "y" is set is pressed, the key 2 for which the vowel "i" for voiced sound is set.
Even when 8 is pressed, one of "yu"("yuu" or "yu") "or" you "(" you "or" kyo ")" is entered and "y" is set. When the key 31 in which the voiced vowel “e” is set is pressed after 32 is pressed, it is more preferable that the other of “yuu” or “you” is input.

Here, in Roman alphabet input, "yi",
Characters based on the combination of "yes" are not set. Therefore, a special kana character or the like can be set for such an input operation. Therefore, if set as described above, especially after the kana character keys 22 to 27 and 29,
By entering a combination of "yi" and "ye", you can easily enter a character string that contains long consonants such as "sho" and "shu", which are frequently used in Japanese, and enter sentences more efficiently. it can. Also, kana character keys 22 to 24, 2
If "y + voiced vowel i" or "y + voiced vowel e" is input after pressing 6, you can easily input choruses including voiced sounds such as "Gyo" and "Gyu". You can enter sentences more efficiently.

Here, the key 27 in which the vowel for voiced sound is set
When the key 26 having the function of confirming the input of a single vowel is pressed after .about.31 is pressed, the vowel indicated by the keys 27 to 31 in which the vowel for the vowel is set is input as a single vowel in lower case. Preferably.

In such a structure, for example, after pressing the key for which the vowel for the voiced sound is set as the first keystroke, pressing the key for confirming the input of the single vowel as the second keystroke, If lowercase single vowels corresponding to the indicated vowels are set to be input respectively, lowercase single vowels can be input by two keystroke operations. Therefore, considering that the existing input method requires two to six keystroke operations, the number of keystrokes when inputting a lowercase single vowel is equal to or less than that of the existing input method. The input speed can be improved.

After pressing the key in which the kana character "ya" is set, press the key in which the voiced vowel for the vowel "a, u, o" is set, and the lowercase letter "ya" in the "ya" line is pressed. Shu
It may be set so that each "" is input. In this way, the lowercase letter "ya, yu, yo" in the "ya" line can be input by two keystroke operations. Therefore, in consideration of the fact that the existing input method requires 2 to 6 keystrokes, the lower case “ya, yu, yo” in the “ya” line is input compared to the existing input method. The number of keystrokes can be made equal or less, and the input speed can be improved.

Also, the three main keys 21 to 23 in the first row
, In order from the left key, "a", which is a vowel for cleansing,
"I" and "u" are written respectively, and the two main keys 24 and 25 from the left side of the second row are, in order from the left side key, "e" and "o" which are vowels for clearing, respectively. The three main keys 27 to 29 in the third row are, in order from the left key, “a”, “i”, and “u” which are vowels for dakuon.
It is preferable that the two main keys 30 and 31 from the left side of the fourth row have the vowels “e” and “o”, which are the vowels for the dull sound, respectively, in order from the left side key. .

By doing so, it is possible to input a kana character or the like while visually confirming the vowel for the pure sound or the vowel for the voiced sound displayed on the key top. Therefore, it is possible to surely and quickly input a text or the like. Furthermore, if the vowels for the pure sound and the vowels for the voiced sound are written in alphabets, they can be easily distinguished from the kana characters "a, ka, sa, ... wa",
Even if each vowel and kana character is written on each key, it can be easily recognized.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. This embodiment is used as a mobile phone 1 as shown in FIG. The mobile phone 1 is provided with a liquid crystal display 2 and a key input device (key input unit) 3 in which a plurality of keys are arranged.

As shown in FIG. 2, the key input device 3 according to the present invention is provided with a function key portion for performing various operations on the upper portion, and a total of 1 row of 5 rows vertically and 3 columns horizontally on the lower portion.
Five keys are arranged, and a total of twelve keys 21 to 32 in four rows and three columns under the keys constitute a main key for inputting numbers and characters. Further, telephone function keys 41 to 43 for performing various telephone functions are set in the upper three keys.

Further, above these 15 keys, function keys such as a cursor movement key 51, an enter key 52, a menu key 53, a mode key (character key) 54, and a key 55 for displaying a telephone directory are arranged. Has been done. The mode key 54 is for inputting numbers (telephone number), English (uppercase letters,
In addition to the first input mode similar to a conventional mobile phone such as a lowercase character input mode and a Japanese input mode, a function to switch to a characteristic second input mode (CUT type input mode) of the present invention is provided. When the mode key 54 is pressed, the above modes can be sequentially switched.

The cursor movement key 51 is used not only for moving the cursor (character input position), but also for inputting a space, and selecting a candidate for kanji conversion in kana input. The enter key 52 is used to enter an input such as to determine the kanji selected during kanji conversion.

Characters and functions are set in the main keys 21 to 32. That is, each main key 21 to 32
On the left side of the key top, numbers used when entering a telephone number, etc. are written, and on the right side, Kana characters for Japanese input and English input by the conventional input method (first input mode) are written. The alphabet used is described.

Specifically, as shown in FIG. 2, each key 21
On the left side of the key tops of 32 to 32, as a numerical sequence, from the left side of the upper row, the key 21 has a number “1”, the key 22 has a number “2”, the key 23 has a number “3”, and the key 24 has a number “4”. , The key 25 has the number “5”, the key 26 has the number “6”, the key 27 has the number “7”, the key 28 has the number “8”, the key 29 has the number “9”, and the key 30 The symbol “*”, the number “0” on the key 31, and the symbol “#” on the key 32 are set so that telephone operation can be performed.

Below the key tops of the main keys 22 to 29, 3 to 4 alphabetical letters "A to Z" for inputting English in the conventional alphabet are written on each key.

On the upper side of the key tops of the main keys 21 to 29, kana characters for Japanese input in the conventional Japanese syllabary order "a, ka, sa, ta, na, ha, ma, ya, ra" are displayed. Each is listed. Further, a kana character “wa, n” is written on the key top of the key 31. In the second input mode (CUT type input mode), when the keys 21 to 29, 31 on which these kana characters are displayed are pressed as the first keystrokes, they are written on the key tops of the keys 21 to 29, 31. The line indicated by the displayed kana character is selected. For example, key 24
When is pressed once, "ta row" is selected. If you press the key 26 twice in a row, "ha row"
“Pa” indicating the semi-voiced sound of is selected.

On the other hand, on the upper right side of the key tops of the main keys 21 to 32, characters and symbols used only in the second input mode are written. That is, each key 2
On the upper right side of the key tops 1 to 25, “a”, “i”, “u”, “e”, and “o”, which represent the vowels for clearing, respectively, are transferred from the key 21 to the key 25 from left to right, They are listed in the order "aiueo". In the second input mode, each of these clear vowel keys 21 to 25 is pressed after pressing the kana character keys 21 to 29 and 31, so that each key in the pressed kana character line is pressed. Vowels “a (a), i (i), u (u), e (e), o displayed in 21 to 25
The character of the Kiyone in the column corresponding to (O) ”is input.

On the upper right side of the key tops of the keys 27 to 32, "a", "i", and vowels representing the vowels for the voiced sound, respectively.
“U”, “e”, “o” (note that the vowel “a,
The symbols "^" are attached to the upper side of the characters "i, u, e, o") are displayed from the key 27 to the key 31 from left to right in the order of "aiueo", In the second input mode, each key 2 of the lines selected as the first keystroke is pressed by being pressed as the second keystroke.
The vowels "a (a), i (i), u" displayed in 1 to 25
The voiced characters in the columns corresponding to “(u), e (e), o (o)” are input.

On the upper right side of the key top of the key 26, an "x" indicating the function of confirming the input of a single vowel is written, and in the second input mode, a vowel for a pure sound is set as the first keystroke. After pressing the keys 22 to 25, the key 26 having the function of confirming the input of a single vowel as the second keystroke is pressed to display the vowels "i (i), u" displayed on the keys 22 to 25.
"(U), e (e), o (o)" are input as single vowels. In addition, when the keys 27 to 31 in which the vowels for voiced sound are set as the first keystroke are pressed and then the key 26 is pressed as the second keystroke, the lowercase letters of the vowel "A, i, u, eh, ぉ" It is supposed to be entered.

On the key top of the key 30, a consonant sound "tsu" and a long sound "-" are written, and in the second input mode,
When the key 30 is pressed as the first keystroke, a consonant "t" is input, and when the key is pressed twice, a long tone "-" is input as the second keystroke.

On the upper right side of the key top of the key 32, a character "y" indicating a half vowel used for inputting a Japanese syllable is written,
Key 2 with kana characters set in the second input mode
1 to 29, 31 and keys 21 to which vowels for clearing sounds are set
By pressing "y" of the key 32 between the key 25 and the keys 26 to 30 in which the vowel for the voiced sound is set, a jumble is output.

The keys input in the second input mode are summarized in FIG. In FIG. 3, on the key tops of the keys 21 to 32, a row of kana characters to be input as the first keystroke is shown on the left side, and vowels to be input as the second keystroke (for vowels for vowels and voiced sounds). Vowels), semi-vowels, and letters that indicate the function of determining single vowels are shown on the right side. For the key 30, continue to 2
The long sound "-" that is input when the key is pressed twice is written on the lower left side, and the kana character "n" that is input when the key is pressed twice consecutively is written on the lower left side of the key 31. .

This kind of input is almost the same as the method for inputting romaji in Japanese, and with the recent spread of personal computers and the like, the majority of users who input Japanese use romaji. It has the advantage of being easy.

In the keys 21 to 25, the vowels indicated by the vowels "a, i, o, u, e" for the pure sound and this key 21
Keys 27-31 located two steps below the
The vowels for the voiced vowels "a, i, o, u, e" are arranged so as to correspond to each other. Therefore, the array of vowels can be easily remembered.

Next, the input processing function of the key input device 3 having the above-mentioned key layout will be described with reference to the block diagram shown in FIG. First, the key input detection means 101 detects whether or not each of the keys 21 to 32 is tapped. For example, a timer interrupt may be performed in a fixed cycle (for example, 1 to 10 ms), and the I / O port or the like assigned to each key 21 to 32 may be checked to see if there is a key input.

When it is determined that there is no key input, the timer interrupt is repeated in a fixed cycle to wait for the key input. On the other hand, if it is determined that there is a key input, the key input processing means 102 performs input processing. When the mode key 54 is pressed to switch the input mode, the mode switching means 103 is activated and the key input processing means 102 is operated.
The input mode of is appropriately switched and set.

The key input processing means 102 processes so that predetermined characters, numbers, etc. are output according to the set input mode and the input key. Then, the output characters and numbers are displayed on the liquid crystal display 2 via the screen control means 104. The input operation in each mode will be described below.

[Normal mode in the first input mode] Since the normal mode is a mode that functions as a mobile phone, when each of the keys 21 to 32 is pressed, the key input device 3 switches to the keys 21 to 32. Output the set number. Therefore, if the telephone is in the outgoing state, the telephone number can be input to make a call. Also, since it is a mode in which numbers can be entered, it can be used when entering numbers as in the case of entering a telephone number in a telephone directory.

[Alphabet input mode in the first input mode] When the mode key 54 is pressed to switch to the alphabet input mode, each key 21 to
When 32 is pressed 1 to 4 times, the alphabet written on each key top is input.

[Conventional Japanese input mode in the first input mode] When the mode key 54 is pressed to switch to the Japanese conventional input mode, like the conventional mobile phone,
By pressing each of the keys 21 to 29 and 31 1 to 5 times, the characters "A line to W line" written on the upper side of each key top are appropriately input.

[Second Input Mode (CUT Type Input Mode)] An example of character input in the second input mode will be described with reference to FIG. In addition, in FIG. 5, an example of inputting each word is shown, and the input operation of the character in parentheses is a kana character and vowel (alphabet) written on each key 21 to 32, and Two types of numbers and symbols “*, #” set on the keys 21 to 32 are described.

(Entering a pure vowel / single vowel) When the mode key 54 is pressed to switch to the second input mode, the keys 22 to 29, 3 in which the kana character is set as the first keystroke.
When you press 1, the line "ka line," which corresponds to the written kana character
Sa line, ta line, na line, ha line, ma line, or line, la line, w line ”are selected. When the key 21 is pressed as the first keystroke, the kana character "a" is input as described later.

After the "row" is selected in this way, the keys 21 to 25 for which the vowels for the clear sound are set as the second keystrokes.
When you press, the key 21-
The vowels indicated by 25 are "a (a), i (i), u (u), and e.
(E), o (o) ”, and the kana of kana in the column corresponding to“ ”is input.

For example, when the keys 26 and 23 are sequentially pressed once each time, "ha" is input in "ha + u". Similarly, when the keys 26 and 22 are sequentially pressed once, "hi" is input. Similarly, for the other Kana characters of Kiyone, keys 22 to 29, 3
After pressing 1 once, pressing the vowels for syllables of keys 21 to 25 reads "ka line, sa line, ta line, na line, ha line, ma line, ya line,
Each of the kana characters of "Ra line, Wa line" is input. The kana character "o" is input as a row of the vowel "o" in the "wa" line, and is input by pressing the "wa" key 31 and the "o" key 25 in this order.

More specifically, as shown in FIG. 5, when the word "Hirameki" is input as the input of a word containing the Kiyone kana character, the kana character "ha" key 2
6, vowel "i" key 22 for clearing, kana "ra" key 2
9, vowel "a" key for Kiyone, kana character "ma" key 2
7. Vowel “e” key 24 for clear voice, Kana “ka” key 2
2. Keystrokes are input in the order of the clear vowel “i” key 22 (in the figure, i, a, e, or i). In addition, each key 21 to 3
When the keystroke order is indicated by the numbers “0 to 9” and the symbols “*, #” described in No. 2, as shown in FIG.
22 ”.

When inputting the word "Tanoshimi", as shown in the figure,
The keys are input in the order of 72).

Also, after pressing the keys 22 to 25 for which the vowel for the clear sound has been set as the first keystroke, the key 26 in which "x" representing the function of confirming the input of the single vowel as the second keystroke is written. By pressing, the vowels “i (i)”, “u (u)”, “e (e)” written on the keys 22 to 25,
“O (o)” is input as a single vowel. For example, if you press the keys 22 and 26 one by one, "i + x" will result in "I".
Is entered. Similarly, when the keys 23 to 25 for which other vowels for the pure sound are set as the first keystroke are pressed, "u", "e", and "o" are input as single vowels. In addition, when the key 21 in which the vowel for a pure sound indicating the vowel "a" is set as the first keystroke is pressed,
The single vowel "A" is input only by this keystroke.

As an input of a word containing a single vowel, for example,
When entering the word "greeting", the kana character "a"
Key 21, vowel “i” key 22 for clear voice, function “x” key 26 for confirming input of single vowel, kana “sa” key 2
3, vowel "a" key 21 for vowels, kana "ta" key 2
4) The vowel for vowel "u" key 23 is input in this order (in the figure, u = 1263143). Also,
When inputting the word "Koueki", as shown in the figure,
Keys are input in the order of (or auxex or i = 25364622).

(Input of voiced / semi-voiced sound) On the other hand, after the keys 22 to 24, 26 (ka, sa, ta, ha) are selected by the first keystroke, the vowel for the voiced voice is set as the second keystroke. When the key 27-31 is pressed, the vowel “a” indicated by the key 27-31 that is tapped is selected in the selected “ka, sa, ta, ha line”.
The kana of kana in the column corresponding to "(a), i (i), u (u), e (e), o (o)" is input.

For example, when the keys 26 and 29 are sequentially pressed once each, "bu" is input by "ha row + (u)". Similarly, when the keys 26 and 28 are pressed in sequence, "vi" is input.
Similarly, for other kana kana characters, by pressing the keys 22 to 24 and 26 once and then pressing the voiced vowels of the keys 27 to 31, each of "Ka line, Sa line, Ta line, Ha line" Characters are entered.

After pressing the key 26 twice in succession,
By pressing the keys 27-31 that have vowels for dakuon,
The semi-voiced sounds of “PA”, “PI”, “PU”, “PE”, and “PO” are input.

More specifically, as shown in FIG. 5, when inputting the word "event" as a word including a kana kana character, for example, the kana character "ta" key 2
4. Vowel vowel "e" key 30 and kana "ka" key 2
2, vowel "i" key 22 for clearing, kana character "ka" key 2
2. Vowel vowel “o” key 31 and Kana “ta” key 2
4, the vowel "o" key 25 for clearing sounds is input in this order (in the figure, e or i or o, o = 4 * 222045). In addition, when inputting the word “prefab” as the input of a word including a semi-voiced kana character, as shown in the figure, the key is input in the order of (ha u u al e a = u = 669946169). It

(Input of consonant sound / long sound) The consonant sound "tsu" is input by pressing the key 30 once. In addition, long sound "-"
Is input by pressing the key 30 twice.

As a word input including a consonant and a long sound,
For example, when inputting the word "lucky", the kana character "ra" key 29, the vowel "a" key 21 for clearing, the consonant "tsu" key 30, the "ka" key 22 for kana, and the vowel "i" for clearing Key 22, long-sound “-” key 30, long-sound “-” key 30 in that order (in the figure, a-a or i- = 91 * 22 **). Also, when inputting the word "zipper", as shown in the figure, (i is a = 38).
Keystrokes are entered in the order of * 667 **)

As described above, for the input of (and input of a line and a Japanese syllabary) and a line, the kana vowel keys 21 to 25 to which the respective vowels for the syllabary are set are pressed next to the key 28 of the kana character. It will be entered. For example, when inputting the word “Yukiyoke” as a word including “ya line”, the kana character “ya” key 28, the vowel for vowel “u” key 23, the kana character “ka” key 22, The vowel "i" key 22 for clearing, the kana "ya" key 28, the vowel "o" key 24 for clearing, the kana "ka" key 22, and the vowel "e" key 24 for clearing are entered in this order. (In the figure, u or i or o e = 83228
524).

Further, keys 22 to 2 in which kana characters are set
By pressing the “y” key 32 between the keys 7 and 29 and the keys 21 to 25 in which the vowels for the clear sound are set or the keys 27 to 31 in which the vowels for the dull sound are set, the swirling sound is input. For example, when the keys 22, 32 and 21 are sequentially pressed once, "ka" is input by "ka line + y + vowel for cleansing a". Also,
If you press the keys 22, 32 and 31 once in sequence, "ka line + y
"Gyo" is input with + voiced vowel o. Therefore, for example, the word "Gyosha" is used as the input of a word containing a whistle.
When inputting, the kana character “ka” key 22, the half vowel “y” key 32, the voiced vowel “o” key 31, the kana character “sa” key 23, the half vowel “y” key 32, the pure vowel “vo” Keys are input in the order of "a" key 21 (in the figure, y
o sa = 2 # 03 # 1).

(Abbreviated entry of "Yu" and "Yo") Generally, the kana characters of "Ya line" are "Ya, Yu, Yo".
Only characters are set, and no characters are particularly set in the “i” and “e” stages of “ya line”. For this reason, if the "ya" key 28 is pressed as the first keystroke and then the "i" key 22 is pressed as the second keystroke, a character string of "Yu" which is relatively frequent in Japanese is input. Is set to. Also, in the same way, press the “YA” key 2
8. When the user presses the "e" key 24 in this order, the character string "you" is set to be input. For example, when inputting the word "Yuyou", as shown in the figure, the keys are input in the order of (or i or e = 8284).

(Abbreviated input of "you" and "yuu") In Japanese, "you" and "yuu" are input as long tones of Japanese syllables. It is often done. In normal input, since three characters are input, three keystroke operations are required. However, in the present embodiment, a consonant key is followed by "y + quiet vowel i.
When "(key 32, 22)" or "y + voiced vowel i (key 32, 28)" is input, "yuu" is input. In addition, following the consonant key, "y + vowel for clear sound e
(Keys 32, 24) ”or“ y + voiced vowel e (keys 32, 30) ”is input, so that“ you ”is input, so that a long sound of a chorus can be input by double tapping. Is set.

Here, the vowels i and e for the clear sound (keys 22 and 2)
By selecting 4) and the vowels i and e (keys 28 and 30) for the voiced sound, it is possible to select whether the consonant input before the “y” key 32 is to be a pure sound or a voiced sound. Therefore, for example, when inputting the word "shugyo", as shown in the figure, the keys are input in the order of (say yi or y voiced vowel e = 3 # 22 # *).

In the above input, the consonant key is not input, and "y + quiet vowel i (keys 32, 2
2) ”or“ y + voiced vowel i (key 32, 28) ”,
When “y + vowel for clear sound e (keys 32, 24)” and “y + vowel for vowel e (keys 32, 30)” are input,
Since no particular setting is made, the following setting can be adopted, for example. That is, in Japanese, "you" and "Yu" are frequently input, so the consonant key is not input, and "y + quiet vowel i (key 32, 2
2) ”or“ y + voiced vowel i (key 32, 28) ”
Set so that "Yu" is input when is input. Similarly, without inputting the consonant key, “y + quiet vowel e (key 32, 24)” or “y + voiced vowel e
When "(key 32, 30)" is input, "you" is set to be input.

Further, following the consonant key, "ya + vowel for clear sound i (keys 28, 22)" and "ya + vowel for voiced sound i
(Key 28, 28) "," Ya + vowel for clear sound e (key 2
8, 24) ”,“ V + e vowel e (keys 28, 3)
Even when "0)" is input, since no particular setting is made, the following setting can be adopted, for example. In other words, the consonant key is followed by "and + vowel for cleansing i
When "(keys 28, 22)" or "or + voiced vowel i (keys 28, 28)" is input, "yuu" is set to be input. In addition, when "or + clear vowel e (keys 28, 24)" or "or + voiced vowel e (keys 28, 30)" is input after the consonant key, "you" To be entered. Even in such a setting, since "ya" and "y" are associated with each other in Roman character input, no particular discomfort occurs. It should be noted that, in the case of inputting Roman characters, no character is set by the combination of "yi" and "ye", so there is no problem in assigning these abbreviated inputs.

(Wa, sound input) In addition, sound input "n"
Is input by pressing the key 31 twice. In addition, for example, when inputting the word "Waokuku" as a word including "Wa row", as shown in the figure, keystrokes are entered in the order of (Wa ao or a or u = 01052123). Is entered.

Further, as an input of a word containing "sound repellency",
For example, when inputting the word "zen", as shown in the figure, the keys are input in the order of (saen ixn = 3 * 002600).

(Input of Small Letters / Symbols) Small letters of vowels and jumbles are input using the keys 27 to 31 in which the vowels for dakuon are set. Specifically, the vowel keys 27-31 for voiced sound
After pressing, press the "x" key 26 for vowel confirmation,
The vowel lowercase letter "aahhhh" is entered. Also,
After pressing the "YA" key 28 key, the vowel key 2 for voiced sound
When 7, 29 and 31 are pressed, a lowercase letter "yu" is input, and when the "wa" key 31 is pressed and then the vowel key 27 for voiced sound is pressed, "㎎" is input. That is, as shown,
The character string "Aiu-A-Yu-Au" is (axixuxex
ox or a or u or o a = 768696 * 6068789
Keystrokes are input in the order of 8007).

In the present embodiment, "hiragana" and "katakana" can be input as kana characters, and these can be appropriately selected by pressing the mode key 54.

Further, conventionally, when a kana character in the Japanese syllabary arrangement is input to a mobile phone, the character is fixed by pressing the cursor key for each character and performing a feed operation.
In this embodiment, basically "line (consonant) + dan (vowel)"
Since the keys are pressed in the order of, the keys 21 to 25 in which the vowels for the clear sound are set or the keys 27 in which the vowels for the dull sound are set
Characters can be confirmed when ~ 31 is pressed, and the feeding operation is not required. Also, when the cursor movement key 51's down movement key is pressed after inputting a character, it is converted into a Chinese character, and the left and right movement keys sequentially select the conversion candidates for that Chinese character.

According to this embodiment as described above, the following effects can be obtained. (1) Since the mobile phone 1 can select the new second input mode as the key input device 3 in addition to the Japanese input mode (first input mode) of the conventional mobile phone, Users who are accustomed to the input method can use it without any resistance. Therefore, the operator who used the conventional input method can easily experience the second input mode by switching the input mode with the mode key 54.
A user who is shy to just because he is not accustomed can shift to the second input mode and perform efficient key input.

(2) Even the manufacturer of the mobile phone 1 does not need to manufacture two types of mobile phones 1 having different input methods, and only one type of mobile phone 1 needs to be manufactured, so that the manufacturing cost is reduced. At the same time, it can meet the needs of the market that requires an efficient character input method.

(3) In the second input mode, the most frequently used vowels in Japanese, "A", "I", "U",
"E" and "O" are different keys 21 to 25, 27 respectively.
Set to ~ 31 and use the kana character "ka, sa, ta,
Na, ha, ma, ra, wa "with different keys 22 ~
Since it is set to 29 and 31, keys 21 to 29 and 31 in which kana characters are set, and keys 21 to 29 in which vowels for clearing are set
It is possible to easily input a kana character by simply pressing the key twice in the order of either one of the keys 27 to 31 in which the vowel for voiced voices 25 or the vowels for voiced sound is set. Therefore, compared to the conventional mobile phone, the number of keystrokes at the time of character input can be reduced, the input operation can be simplified, and the kana character can be input very efficiently. For example, in the case of inputting the example sentence shown in FIG. 6, in the conventional mobile phone input (first input mode), 83 keystrokes are required, whereas in the second input mode of the present embodiment, 46 keystrokes are required. In addition, the number of inputs can be greatly reduced compared to the conventional one, and high-speed input can be performed. In particular, the number of inputs can be suppressed to the same as that of the input of Roman letters (46 keystrokes) on a general personal computer, and the input operability can be greatly improved.

(4) Keys 21 and 2 to which the vowels for the clear voice are set
Since 5 and the keys 27 to 31 in which the vowels for voiced sounds are set are set to different keys, the kana characters of the voiced sounds can be input in the same manner as the kana characters of the pure sound. For this reason, the kana kana character input can be performed with a smaller number of keystrokes and a simple input operation as compared with the conventional mobile phone input method. In addition, since the voiced sound is used relatively frequently in sentences, the input speed of sentences can be effectively improved.

(5) Vowels "a", "i", "u" for clearing
"E" and "o" are arranged from the first stage to the second stage and from left to right, and the vowel for voiced sound "a",
"I", "u", "e", and "o" are the third to fourth
Since they are arranged from the left to the right toward the step,
Since the user is accustomed to the "aiueo" order, the position of the vowel key can be easily grasped and the input speed can be improved.

(6) The vowel "a" for the pure sound in the upper two stages,
Arrays of “i”, “u”, “e”, and “o”, and vowels “a”, “i”, “u”, “e” for vowels in the lower two stages
Since the arrangement of “o” is set to be relatively the same, the kana kana character input can be operated in the same manner as the kana kana character input and can be easily adapted.

(7) Since the key 26 is set to have a function of confirming the input of a single vowel, the key 2 to which the vowel for the clear voice is set is set.
1 to 25, the "x" key 26 having the function of confirming as a single vowel is pressed in that order to perform "I,
You can input each vowel "U, E, O" as a single vowel. Therefore, as compared with the existing input method, the number of keystrokes at the time of inputting a single vowel can be made equal or less, and the input speed can be improved.

(8) Keys 21 to 2 to which the vowels for clearing sounds are set
Since 5 is frequently used in text input, the position of each vowel for a vowel is familiar to the user. Therefore, when inputting a single vowel, the vowel for the vowel corresponding to the vowel The finger tends to momentarily move to the position of the keys 21 to 25 where the vowel is set. Accordingly, the keys 22 to 25 and the "x" key 26, in which the pure vowels corresponding to the vowel "i, u, e, o" are set, are input in the order of the single vowels. Compared with the case of inputting a vowel, a single vowel can be input quickly in accordance with the reflexive finger movement, and an input error due to the reflexive finger movement can be prevented, so that an input operation can be performed efficiently.

(9) Since it is set that the key 30 is pressed once to input the consonant "t", and then the key 30 is pressed again to input the long sound "-", it is possible to perform the long sound by tapping the key once or twice. And you can input consonants. Therefore, in consideration of the fact that the general existing input method requires about four keystrokes to input a consonant "tsu", and at least about three keystrokes to input a long sound "-". Compared to the input method of, the number of keystrokes at the time of inputting a consonant and a long tone can be reduced, and the input speed can be improved.

(10) Keys 22 to 2 in which kana characters are set
4, 26, semi-vowel “y” key 32, keys 21, 23, 25 with clear vowels or keys 27, 29, 31 with vowels for dakuon are input in order to input a chorus Since the setting is made, a tapping sound can be input with three keystroke operations. Therefore, in the general existing input method,
Considering that it takes two keystrokes to input consonants in the “i” stage and two to six keystrokes to input the half vowel “ya, yu, yo”, compared to existing input methods. , It is possible to reduce the number of times of keystrokes at the time of tapping sound input, and improve the input speed.

(11) Type the "ya" key 28 and the vowel "i" key 22 for clearing sound in this order to enter the kana character string "Yu",
Since the "ya" key 28 and the clear vowel "e" key 24 are pressed in order to input the kana character string "Yo", relatively frequent characters such as "Yo" and "Yu" You can easily enter columns and enter sentences efficiently.

(12) Keys 27 to 3 in which the vowel for the dull sound is set
1. Press the "x" key 26 in this order, and set to input the lowercase single vowels "a, i, u, eh, ぉ" corresponding to the keys 27 to 31 to which the vowels for dakuon are set. As a result, a small single vowel can be input with two keystrokes. Therefore, considering that the existing input method requires two to six keystroke operations, the number of keystrokes when inputting a lowercase single vowel is equal to or less than that of the existing input method. The input speed can be improved.

(13) Press the "YA" key and the keys 27, 29, 31 in which the vowels for vowels "A, U, O" have been set in that order, and the lowercase letters "YA, "," Is set so that you can enter each of them.
You can enter lowercase letters "ya, yu, yo" on the line. Therefore, the number of keystrokes at the time of input can be made equal to or less than that of the existing input method, and the input speed can be improved.

(14) Since the vowels for the clean and the vowels are written on the key tops of the keys 21 to 25 and 27 to 31, it is possible to visually check the vowels for the clean vowels or the vowels and to identify the kana characters and the like. You can enter. Therefore, it is possible to surely and quickly input a text or the like. Furthermore, in each of the keys 21 to 25 and 27 to 31, the vowels for the pure sound and the vowels for the voiced sound and the kana characters are set to the same key, but these vowels are written in alphabets, and the kana characters are written in hiragana. Therefore, it can be easily identified and input can be performed smoothly even during input operation.

(15) Kana character "n" key 31 is pressed twice to input a vowel "n", keys 22 to 24, 26 in which a kana character is set, a half vowel "y" key 32, and a clear sound Keystrokes are entered in the order of keys 21, 23, 25 in which vowels are set, so that the input sound is input. Therefore, since the input is made by the combination of characters according to the Roman character input on the conventional general keyboard, the key operation is performed. It can be learned quickly, the operability can be improved, and data can be input at high speed.

The present invention is not limited to those described in the above embodiments. For example, the vowel "a" for the pure sound,
The relative positional relationship of the keys for which “i”, “u”, “e”, “o” and the vowels for dakuon “a”, “i”, “u”, “e”, “o” are set are: Not limited to the above embodiment,
For example, when there are twelve keys 21 to 32 arranged in four rows in the upper and lower rows and three rows in the left and right directions, the vowels "a", " i ",
Set "u", "e", and "o", and press the key 30 on the third row.
You may set a vowel for voiced sounds from the 32nd to the 4th step keys 27-29.

Further, in the above-described embodiment, the vowel for the dull sound is set to the key two steps lower than the key for which the vowel for the clear sound is set. However, the present invention is not limited to this. Etc. may be set. However, the above-described embodiment has an advantage that it is easier to remember the arrangement of vowels.
