[Industrial applications]

 The present invention relates to a Romaji input keyboard, and in particular, a Romaji input keyboard that accelerates the speed at which an operator manually inputs Japanese using the keyboard by using a keyboard or keypad-like device such as a computer terminal device, word processor, or electronic notebook. Related to.

[Prior art]

 As a type of keyboard layout, a JIS standard JIS layout keyboard is generally used. The JIS layout keyboard takes into account the frequency of appearance of English alphabets and has 26 English letter keys. Normally, when inputting Roman characters, no matter which keyboard pattern is used, for example, in the case of "Kami", "KA + MI" and four characters are input and the conversion key is pressed. In this way, other than vowels, multiple alphabets are input, and the Romaji-kana conversion function is used to perform Romaji input.

FIG. 3 shows an example of a conventional keyboard having keys of 100 syllables. In the example of the figure, five keys of vowels are arranged at the upper left position and consonants are added to each vowel (vowel + consonant). For example, consonants “k”, “s”, and “t” are added to vowels. , "N", "h", "m", "r", and "g" are used to change the line, line, line, line, line, line, line Represent it and place it on the left side of the keyboard. In addition, each vowel has a consonant (vowel + consonant) "z", "b", "p", and "w" attached to represent a row, a row, a row, and a row. , "D" are added to indicate a line and a line. In addition, consonants “k” and “s” are indicated by a key “y”, which means “kya, kyu, kyo” and “sha, shu, sho”. These keys are arranged at the center of the keyboard, and the remaining (consonant + Jong + vowel) patterns are arranged on the right side of the keyboard. Therefore, the number of keys on this keyboard is 9 (vertical) × 13 (horizontal) -17 (blank), which is a key of 100 syllables.

Further, FIG. 4 shows a keyboard having a key in which only the vowel keys are separated and all the consonants and jingles are combined. The total number of keys of the keyboard shown in the figure is 30 keys, which is considerably smaller than that of the keyboard of FIG.

[0005]

[Problems to be solved by the device]

 The JIS layout keyboard as described above has a problem that it requires a considerable amount of skill in order to be able to input Japanese text in Roman characters at high speed because there are 26 English character keys.

[0006] On the other hand, with a keyboard using "kana" as a kanji character, it is sufficient to press the key once for many phrases, but the number of keys is as large as 44, and these occur in consideration of the frequency of appearance of Japanese sentences. Since it is placed in the same manner as in the Roman keyboard, it requires skill. In addition, when inputting whistle sounds, consonants, etc., the shift key had to be operated, which was complicated.

Although there is a key arrangement in the order of Japanese syllabary, the number of keys in this case is more than 50, and it takes time to search for the key.

Further, in the case of inputting Roman characters, not all 26 alphabetic keys according to the JIS arrangement are used. For example, "L", "Q", "V", and "X" are keys that are not used in Roman character input. Further, "C" is used as "cha", "chi", "chu", "che", and "cho", respectively, but "tya", "tyi", "tyu", and "tye", respectively. , "Tyo". "J" can also be replaced with "Z". It is safe to delete such keys from a 26 character keyboard. As shown in FIGS. 3 and 4, those keyboards are not initially arranged.

However, when a beginner searches for a key and inputs it, he / she searches for a key, including a key that is not used for the Romaji input character, and inputs it, so the input speed is slow. There is. In particular, the above-described keyboard shown in FIG. 3 has 100 keys, and the time required for a beginner to search for a key becomes long as described above.

The present invention has been made in view of the above points, and reduces the kinds of keys required for inputting Japanese sentences, and also allows the beginners to enter a Roman character that has a key layout that is relatively fast. Intended to provide a keyboard.

[0011]

[Means for Solving the Problems]

 The present invention is a character input keyboard for inputting Japanese sentences by pressing the key corresponding to the romaji. Each vowel key in which roman letters corresponding to a vowel, a consonant, and a syllabary is written is a vowel of a group of vowel keys. The regions are grouped and arranged in a region, a consonant region of a consonant key, and a consonant region of a consonant key group.

[0012]

[Action]

 The present invention arranges the keys used for vowels, the keys used for consonants, and the keys used for chorus into groups so that a total of 5 vowel keys, 13 consonant keys, and 1 chorus key can be arranged. Since 19 keys are arranged, the number of keys is reduced first. Therefore, even a beginner can easily remember the key arrangement. In addition, since the arrangement of keys is grouped into vowels, consonants, and Japanese syllables, it is only necessary to search within the group according to the type of phoneme, so beginners unfamiliar with input can input while checking the keys visually. In such a case, the key search time is shortened.

[0013]

【Example】

 Japanese sentences can be expressed by 100 kinds of syllables in most cases. The breakdown is syllables of only 5 kinds of vowels (V) and syllables of 95 kinds of consonants (C) + V. Furthermore, among these 95 types, there are 33 types of syllables that include the jumble "y" in the middle.

In the case of a beginner, the input speed of a key corresponding to a sentence is mainly governed by the time to search for the corresponding key. Therefore, if the number of keys is reduced as much as possible, the input speed can be increased. There are 13 types of consonants excluding Jingu, which is much easier than searching from among 95 types of keys. For syllables that include Japanese syllables, the keys are placed separately because they come after these 13 consonants. Also, vowels always come later when combined with consonants, so these are also different keys. Therefore, the number of key presses required to input one syllable is three for a syllable containing a Japanese syllable, and twice for a syllable that does not include a Japanese syllable.

Hereinafter, description will be given with reference to the drawings. FIG. 1 is a diagram for explaining an embodiment of the present invention. The layout of the keyboard shown in the figure is such that consonants (“k”, “s”, “t”, “n”, “h”, “m”, “r”, “g” “Z”, “b”, “d”, “p”, “w”) key consonant region 1 is arranged, and in the center of the lower stage thereof, only one Japanese sound “Y” is a Japanese sound region 2, A vowel region 3 of a vowel (“a”, “i”, “u”, “e”, “o”) key group is arranged in the lower part of the chorus region 2. Therefore, in this arrangement, the characters including the syllabary can be input as desired by sequentially keying in from the upper row to the lower row.

For example, when the operator wants to input “ku” from the keyboard, he inputs “k” at the top of the consonant area 1 and “u” (k + u = ku) of the vowel area 3. To input "Gyu", the middle "g" of the consonant region 1, the "y" of the jumble region 2 and the "u" of the lower vowel region 3 are input.

According to the arrangement of the keyboard shown in FIG. 1, since the number of keys on the entire keyboard is only 19, the operator determines whether it is a single vowel character, a consonant, or whether a consonant is added to the consonant. However, in the case of a vowel, one of the five keys is selected, and in the case of a consonant, one of the 13 keys is selected, and then the vowel is added. Also, unlike the JIS arrangement, the arrangement of vowels is a, i, u, e, and o from the left side, so input is possible without being aware of the arrangement.

FIG. 2 is a graph showing trial results of the keyboard of the present invention and the conventional keyboard. In the graph, the vertical axis represents the total input time (seconds) for 100 syllables, and the horizontal axis represents the number of trials. In the graph, a is the result of trial with the keyboard of the present invention, b is the result of trial with the conventional keyboard having 100 syllables shown in FIG. 3, and c is the conventional vowel shown in FIG. This is the result of a trial using a keyboard in which only the keys are separated, and all consonants and jingles are combined.

In the trial method, four keyboard operators randomly generate 100 syllables, and the time from the end of presentation of each syllable to the end of input to the keyboard is in units of 10 ms. It was measured.

As is clear from the results in the figure, the number of trials increases, and if the skill is increased, there is no difference in any key arrangement. However, while the number of trials is small, the input a by the keyboard according to the present invention is better. Shows that the input time is overwhelmingly short and there is an improvement effect.

The arrangement in the consonant area and vowel area on the keyboard is not limited to the above embodiment, and the arrangement order may be changed.

[0022]

[Effect of device]

 According to the above-mentioned present invention, since the keys are separated from the consonants, jumbles, and vowels and are grouped, the key search time is shortened, and the types of keys to be prepared are reduced. It has the advantages of smaller size and faster entry speed even for beginners.
