Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device for inputting Japanese in Roman characters in a computer, word processor or the like.

[0002]

2. Description of the Related Art A keyboard is generally used for inputting Japanese in a computer or word processor. When inputting Japanese using a keyboard, one of two types of input methods, Roman character input and kana input, is used. In the case of Roman letters, "A""I""U""E""O"
If it is a vowel of "A", "I", "U", "E", "O", then one kind of key is used. For example, Japanese input is performed by hitting three types of keys such as “K”, “Y”, and “A”, and when inputting other characters, two types of keys, consonant letter and vowel letter. However, "N" is followed by a vowel letter and "Y"
When a key other than is input, or when "N" (or "M") is input twice in succession, "n" is input. Also, when inputting a catch sound, enter consonant characters
The consonant is input by repeatedly striking it.

[0003]

However, when inputting Japanese with a keyboard, a mistaken keystroke is common. In particular, beginners are not familiar with keyboards and often make mistakes in typing keys. If you make a mistake, you'll need to waste time correcting it. The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a Japanese input device that reduces unnecessary time for correction due to an incorrect key when inputting Japanese. .

[0004]

In order to achieve the above object, in the Japanese input device of the present invention, in the case of romaji input, vowel characters (A, I, U, E,
Prepare a means to assign vowel letters to keys near (O),
A means of overriding the assignment assigned to a key near a vowel when a vowel is entered after the consonant,
A means for converting a vowel letter when the assigned key is input when the assignment of the vowel letter is valid, according to the first input key when the second input key is "Y" or "H" To disable the assignment of vowels,
When the same consonant character is input after the consonant character is input, the means for invalidating the allocation of the vowel character and converting it into "tsu" is provided.

[0005]

Therefore, according to the present invention, even if the vowel character after the consonant character is misspelled, a certain amount of input error can be absorbed, so that smooth character input is possible.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. FIG. 1 shows means for assigning a vowel character to a key near the vowel character on the keyboard according to the present invention. In FIG. 1, reference numeral 11 is a keyboard, 12 is an assignment switching unit, 13 is a consonant sound detecting unit, and 14 is a whining sound detecting unit. When the consonant character is input in the Romaji input mode, the assignment switching unit 12 enables the assignment of vowel letters to the keys near the vowel letter, and when the key assigned the vowel letter is entered, it is converted to the vowel letter according to the assignment. To do. Also, this is a part for performing an operation of switching between valid and invalid allocation of vowel characters. The consonant detection unit 13 detects the consonant and requests the assignment switching unit 12 to invalidate the vowel assignment, and the jumble detection unit 14 detects the jumble and the assignment switching unit.
This is the part that requires 12 to disable vowel assignments.

FIG. 2 shows an example of vowel letter assignment on a keyboard having means for assigning vowel letters to the keys near the vowel letters shown in FIG. In FIG. 2, 11 is a keyboard, 202 is a key “A”, 203 is a key “E”, 204 is a key “U”, 205 is a key “I”, 206 is a key “O”, and 207 is a vowel “A”. , 208 is a key to which a vowel "e" is assigned, 209 is a key to which a vowel "u" is assigned, 210 is a key to which a vowel "i" is assigned, and 211 is a key to which a vowel "o" is assigned. As shown in FIG. 2, the keys 207 to which the vowel “A” is assigned are “Q” and “S”.
The key 208 to which "Z" is assigned and the vowel "E" is "3", "W", "D", "R" and "4", and the key 209 to which the vowel "U" is assigned is "7" and "J". , The key 210 to which the vowel “I” is assigned is “8” and “K”, the key to which the vowel “O” is assigned, and 211 is “9”.
"L" and "P".

When a consonant character is input, only when Japanese characters are input using Roman letters, the assignment switching unit 12 assigns the key arrangement of the keyboard to keys near the vowel character as shown in FIG. In the case of inputting a consonant sound and a Japanese sound, the consonant character is input again after the consonant character, so that the consonant sound detection unit 13 and the Japanese sound detection unit 14 request the allocation switching unit 12 to invalidate the allocation to the vowel sound. By assigning a vowel character when inputting a consonant or a Japanese syllable, an unnecessary conversion to a vowel character is prevented.

FIG. 3 shows a flowchart for assigning a vowel character to a key near the vowel character, and an embodiment using this keyboard will be described below with reference to FIG. Wait for the first input at S ₀ . At S ₁ , it is determined whether the first input key is a consonant character input. If it is a vowel letter, a number, or a symbol, the key is "A""I""U" in S ₂ .
If it is "E" or "O", it will be "A", "I", "U", "E", "O".
If it is a number or a symbol, it is accepted as it is. If the key entered in S ₁ is a consonant character, the key near the vowel character is assigned to the vowel character in S ₃ as shown in FIG. 2, and the second input is awaited in S ₄ . The first input key and the second input key in S ₅ the second input is performed to compare if the same. If the keys are the same, it is determined in S6 whether or not the key is a key to which a vowel character is assigned. As it is converted to a double consonants "Tsu" in S ₇ if the key that has not been assigned a vowel, after disabling the allocation of vowels in S _8, if a key has been assigned a vowel, in S ₉ It converted to a double consonant "Tsu", re-enable the assignment of vowels in S _10. After that, in S ₁₁ , the third input is waited, and in S ₁₂ , it is determined whether or not the third input key is a key to which a vowel character is assigned.

If it is not the same key in S ₅ or if the second input is already accepted as a phoning "tsu", the second input key is entered in S ₁₂ (the third input key after the audible input). Determine if is a key that is assigned a vowel letter. If key vowels are allocated, it is determined that the typo in S ₁₃ 2
2nd according to the assignment of
The key that is input first by converting the input key to vowels
(In the case of after the double consonants input "Tsu") is converted to Kana characters by S ₁₄ in conjunction with. (Hereinafter, () indicates the case after the consonant is input.) In S ₁₂ , if the second (third) input key is a key to which no vowel character is assigned, S
_{At 15} , it is determined whether the second (third) input key is "Y". Wait for the next input in S ₁₆ if it is "Y". Input key of the second (third) in the "Y" unless S ₁₇ to determine whether the "H". To determine whether the first input key (second) in S ₁₈ if it is "H" is "S" or "T" or "D" or "C", "S" or "T" or if "D" or "C", and waits for the next input in S _16. In the S ₁₇ input key of the second first in (3) When the input key is not the "H" and S ₁₈ of the (second) is "S" or "T" or "D" or "C" If not, it is determined in S ₁₉ that the user has made a mistake and the user is notified without conversion to vowels.

When the third (fourth) input is made in S ₁₆ , it is determined in S ₂₀ whether the key is a key to which a vowel character is assigned. If keys assigned to vowel it is determined that the typo of the user in S ₁₃ the input key of the third (fourth) into vowel in accordance with the assignment of Fig. 2, the first in S ₁₄ Convert it into kana characters with the second input key (the consonant "tsu" and the third input key). If it is determined in S ₂₀ that the third (fourth) input key is a key to which no vowel character is assigned, S
_{At 21} , it is determined whether the key is a vowel character. First and second input keys in S ₁₄ if the vowel
Convert to kana characters together with (prompt sound "tsu" and the third input key). If it is not a vowel character, it is determined in S ₁₉ that a typo has been made and the user is notified without conversion to a vowel.

[0012] After disabling the assignment of vowels in S ₂₂ the conversion to kana characters is finished, has to enter the next kana characters in S _0, repeated operation over an input is performed. If you want to input "P7", if you press the key while inputting Roman letters, "7" should be entered as "U" and it will be converted to "Pu", so enter English letters or letters and numbers. When you do, you must enter in a mode that allows you to enter alphanumeric symbols.

[0013]

As described above, by using the Japanese input device according to the present invention, it is possible to input characters efficiently without spending a wasteful time for the user to correct even if the user makes a mistake in typing the key. Has the effect.
