Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a Chinese input keyboard, and particularly to a keyboard for Chinese input that can be used as an ASCII layout keyboard.

[Conventional technology]

Conventionally, in order to key-input kanji on a Chinese word processor, etc., the kanji is written as a string of Roman characters according to their pronunciation, and then this string of Roman characters is inputted using an ASCII layout keyboard, etc., and the kanji is written using this string of Roman characters. By searching a dictionary, I obtained kanji and entered them.

[Problem that the invention attempts to solve]

The conventional Chinese input keyboard described above employs a method in which kanji are written as a string of Roman characters and then input from an ASCII layout keyboard, so there was a problem that it took time and effort to enter kanji using the keys. .

The purpose of this invention was to take into consideration the above-mentioned features of the Chinese language, in which one character in a Chinese character corresponds to one syllable, and most syllables can be divided into vocal initials (initial consonants of words) and rhyming finals (parts that include vowels). The object of the present invention is to provide a Chinese input keyboard that facilitates Chinese key input by skillfully utilizing the following.

[Means for solving problems]

The present invention provides a Chinese input keyboard in which each key corresponds to a vocal initial and a rhyming final, so that one syllable of Chinese characters can be input with a two-stroke key input operation, based on the Chinese Common Language syllable table.
Corresponding to each voice initial so that each voice does not overlap 2
Vocal final input determining means for arranging a seed final on one key and determining that a first stroke key input is a vocal initial key input; and a final rhyming final that determines a second stroke key input as a final final key input. an input determining means, and when it is determined by the final input determining means that the key input is a final key input, a key input that uniquely applies to the initial corresponding to the key input of the first stroke when there are multiple finals corresponding to this key input; and final determining means for determining one corresponding final.

[Effect]

With the Chinese keyboard of the present invention, it is possible to input a single syllable of a Chinese character by using two strokes of key input: the vocal initial key input and the rhyming final key input.
When there are a plurality of finals corresponding to the key input of the second stroke, one final that uniquely corresponds to the initial entered by the key input of the first stroke is automatically determined.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing a key arrangement of a Chinese input keyboard according to an embodiment of the present invention. The Chinese input keyboard 1 of this embodiment has an ASCII layout keyboard as its basic structure, and the alphabet and numeric key layouts are exactly the same as the ASCII layout keyboard. Therefore, it is now possible to write the kanji as a string of Roman characters according to their pronunciation as before, and to enter the kanji by keying in this string of Roman characters.

Moreover, the Chinese input keyboard 1 of this embodiment is as follows:
In order to enable direct key input of frequently occurring kanji, the frequently occurring kanji (commonly used characters) are placed on the keytop alongside alphanumeric characters and numbers.

Furthermore, the Chinese input keyboard 1 of this embodiment
cleverly takes advantage of the fact that in Chinese, each syllable often represents one meaning, and each syllable can be divided into a vocal initial (the initial consonant of a word) and a rhyming final (the part that includes a vowel). One key corresponds to one initial and one final, respectively, and two
It is possible to input a single syllable of kanji using the stroke key input operation.

By the way, Figure 4 shows the Chinese common language syllable table, and as can be seen from this syllable table, there are 21 types of vocal initials and 37 types of rhyming finals in Chinese. Therefore,
If you divide a syllable into two parts, the initial and the final, and enter one syllable with two keystrokes, if you try to arrange the 37 types of finals on the key top, you will need 37 types of keys. An ASCII layout keyboard may not have enough keys.

For this reason, some kind of contrivance is required in order to be able to input one final word with a single key input operation using the same key arrangement as an ASCII keyboard.

Therefore, in the Chinese input keyboard 1 of this embodiment, the 37 types of finals are simplified to 27 types as shown in the simplified syllable table in FIG. 5, and these finals almost correspond to the alphanumeric keys of the ASCII layout keyboard. I'm trying to place it on 27 keys, like so.
In other words, -i is expressed by i, and similarly uan is expressed by i.
As uan, un is simplified as un. Also, o and ou are arranged in the same place. This is because the final is determined by the initial, so when the initial is b, p, m, f, the final is o, and for other cases d, t, n, l, g, k, h, zh, ch,
This is because in the case of sh, r, z, c, and s, it becomes uo. Similarly, ong and iong, ia and ua, iang and
A total of 10 types of finals such as uang, uai, u, ui and ue are grouped into 5 types. As a result, there are 27 types of keys that can input final words. In FIG. 1, the 27 keys in which the finals are arranged are shown surrounded by thick lines for convenience.

Referring to FIG. 2, the key input process in the syllable input mode in the Chinese input keyboard 1 of this embodiment includes the first stroke key input determination step 21.
, the initial input step 22 , the second stroke key input determination step 23 , and the final input step 2
4, a final plurality determination step 25, and a final determination step 26.

Next, the operation of the Chinese input keyboard of this embodiment configured in this way will be explained in FIGS. 3a and 3b.
This will be explained based on a specific example shown in . In the description of the operation of this embodiment, it is assumed that the key input mode of the Chinese input keyboard 1 is the syllable input mode.

First, as shown in FIG. 3a, if the key with the ASCII code N is pressed in the first stroke key input operation (step 21), it is determined that the initial key input is the initial key input, and the initial "N" is input. (Step 22). Next, if the key for the ASCII code L is pressed in the second stroke key input operation (step 23), it is determined that the key input is for the final word, and the final word "in" is input (step 24). Next, it is determined whether there is a plurality of finals (step 25), but since there is only one final, "in", this final "in" is input as is. Therefore, the input syllable is "Nin", and the kanji is searched based on this syllable "Nin". Note that if the kanji corresponding to the syllable "Nin" has a homophone, the kanji is selected by single kanji conversion or compound word conversion.

Furthermore, as shown in FIG. 3b, if the key for the ASCII code H is pressed in the first stroke key input operation (step 21), it is determined that the key input is for the initial, and the initial "H" is input. (Step 22). Next, if the ASCII code Y key is pressed in the second stroke key input operation (step 23), it is determined that the key input is for a final, and two types of finals, "ong" and "iong" are input. (Step 24). continue,
When it is determined whether there is a plurality of finals (step 25), since there are a plurality of finals, the only final "ong" that can be combined with the final "H" is determined based on the simplified syllable table shown in FIG. Therefore, the input syllable is "Hong", and the kanji is searched based on this syllable "Hong". In addition, if there is a homophone corresponding to the syllable “Hong”,
Kanji selection is done by single kanji conversion or compound word conversion.

[Effect of idea]

As explained above, according to the present invention, it is possible to input a single syllable of kanji by inputting two types of keys: a vocal initial and a rhyming final.Since the 37 types of finals have been simplified to 27, the number of keys has been reduced. By reducing the number of keys, it is possible to make key input easier. By reducing the number of keys, it is possible to make a low-cost keyboard. Since the initial and final keys are included in the ASCII layout keyboard, it is easy to enter ASCII codes. This also makes it possible to achieve the following effects.
