Description

[Detailed Description of the Invention] [Technical Field] The present invention provides, for example, various Chinese text creation devices,
The present invention relates to a language input device for inputting Chinese sentences.

U Prior Art] There are broadly two keyboard methods for inputting Chinese characters using Pinyin. One method is to input pinyin by breaking it down into individual alphabets, and the other is to input it as a binary structure of initials and finals.

The advantage of inputting Pinyin by breaking it down into individual alphabets is that it is the same as the English keyboard except for U and 7, which are unique Chinese characters that are not in the alphabet.
It is easy to use for people who are familiar with English keyboards, as it requires almost no effort to memorize new keyboard layouts. The disadvantage is that it is one character in Pinyin such as a, but sh
Pinyin such as uang is composed of six characters, so the number of characters forming the Pinyin is larger than that of the following vocal vowel system, which also reduces input efficiency and input speed. Another disadvantage is that the interpretation of the input character string cannot be determined uniquely unless the inputter is unfamiliar with the input of interval sounds and plays the keyboard.

The advantage of the vocal/final/final method is that the number of keystrokes is reduced because there are two characters per bin. The disadvantage is that while there are only 26 alphabet keys, the total number of initials and initials is more than twice that, so a special key arrangement must be devised.

The composer's method has no meaning as a keyboard invention. The latter method is meaningful as an input device invention, but the conventional technology has been designed to emphasize the frequency of keystrokes and the English keyboard layout, but the total number of alpha-het keys is 2. We were not successful in absorbing more than twice the number of keys, such as initial keys and final keys, into 26 alphabetical keys, and as a result, we violated other types of key areas such as numeric keys.
It was difficult to use, as it was forced to use a multi-key design.

[Purpose of the Invention] The present invention solves the above-mentioned problems seen in the prior art, and provides a Chinese input device that is easy to use for those skilled in English keyboards, and that enables high-speed input with 1 bin in 2 keystrokes. The purpose is to create a.

[Structure of the invention] There are several types of Chinese phonetic transcription.

Currently, the most commonly used method is the pronunciation notation based on the ``Chinese Shenyin Plan'' (hereinafter abbreviated as ``Plan''), which was established by the People's Republic of China in 1958.

In setting the specific initials and finals in the Chinese input device of the present invention, we used the initials table and finals table of the same plan as a guide, and extended them according to the actual usage situation. .

That is, the Chinese input device according to the present invention includes a means for setting a zero-voice final key in Chinese keyboard input, a means for allocating multiple finals to 26 keys corresponding to alpha-heads based on a table of possible combinations of multiple finals and one key, and a continuous In the input series of alphabet-corresponding keys, the odd-numbered alphabet-corresponding keys are used as the initials, and the even-numbered alphabet-corresponding keys are used as the finale. , is characterized by having means for making it correspond to a specific Pinyin code.

Note that the word ``Kawaon'' is referred to here in its Chinese reading, ``Pinino,'' which is currently commonly used in Japan.

Strictly speaking, pinyin is not limited to the Chinese pronunciation notation based on the "Hanese danyin system", but it also includes concepts such as anti-cutting. In other words, pinyin is a concept that captures the sound of a Chinese character by a combination of a vocal initial and a rhyming final, and expresses a specific sound. It uses symbols to describe the structure, and does not rely on a system of individual phonetic notation symbols.

For example, the difference between anti-kiri, wave letter moo, and pinyin essentially means a difference in phonetic symbols, not a difference in phonological structure.

In other words, Pinyin notation has been written since the M-Jin Dynasty using a combination of Chinese characters that do not represent the initials and Chinese characters that represent the initials, and the Pinyin writing that was established during the Republic of China period and is still used in Taiwan today is uniquely designed. The difference is in the sound notation symbol system, in which it is done using symbols with a dovetail shape, and in the ``scheme'' established by the People's Republic of China in 1958, it is done using alphabetical notation.

The present invention is based on the Chinese-like phonetic writing structure consisting of a vocal final and a rhyming final, and is limited to the 1958 "Method", which is a specific symbol system for representing the Chinese phonetic writing structure. It's not a thing.

It is possible to express the present invention by other phonetic symbol systems such as anti-kiri, wa-onjimo, and others, and these expressions are also within the scope of the present invention. The 1958 "Scheme" is taken as an example of the invention because it is the only official phonetic and symbol system for the common language (Mandarin) of the people of mainland China, whose population exceeds 1 billion.

The Chinese phonological system differs depending on the time and space, and the differences in the phonological system in the spatiotemporal system are constant, for example, the Chinese phonological system for cattle and the Cantonese phonological system cannot be included in the scope of application of the present invention. The effectiveness of the present invention is also lost when the distance is greater than . The practical range is large.

[Effects of the Invention] Compared to similar Pinyin-specific keyboards, the present invention has the following distinctive effects.

(+) Since the English keyboard layout is used as much as possible, the keyboard layout is easy to use for many users who are accustomed to English keyboards. Most of the initials and the rhyming final aeio
u is the same as the English keyboard layout. In reality, all you need to learn new is the compound final arrangement.

(2) Compound final sequences, such as iong and ong.

It's easy to remember because it's designed to put related finals together, such as uang and iang.

(3) High-speed input is possible because the keyboard layout reduces the frequency of key use.

EXAMPLES Below, examples of the present invention shown in the drawings will be explained.

The specific keyboard layout of the Chinese input device according to the present invention is shown in FIG. 1, and the Pinyin keyboard layout is shown in Table 1. This Chinese phonetic notation symbol system is based on the phonetic notation symbol system of the 1958 1st Plan, and has been expanded upon by adding a zero initial. The present invention relates to a Pinyin-specific keyboard design, which is an independent design in itself, but considering that it is a design that takes full advantage of the English keyboard layout (QWERT), the following is for convenience of understanding. Add an explanation in relation to the English keyboard.

In addition, in the following explanation, for convenience, the initials and the English alphabet are written in uppercase letters, and the final words are written in lowercase letters to make it easier to see the difference in the treatment of each symbol.

The specific design of the present invention will be explained below.

<Space below> The keyboard in Figure 1 has the same layout as the English keyboard layout (QWERT). Table 1 shows the layout of the Bin-in keyboard device, and the keyboard in Figure 1 The initials of the first keystroke (odd numbers) and the finals of the second keystrokes (even numbers) are shown in correspondence with the English keyboard arrangement. It is indicated by a symbol set based on the "New sound scheme".

Table 2 shows an example of a keyboard compatible bin-in chord bulletin,
Use the tree chart to identify the finals for allophone finals. In order to clarify the situation in which different words are distinguished by the tree table, the corresponding internal bin-in codes are shown, but the internal bin-in codes themselves shown here have no essential relation to the present invention.
If the design is such that each bin-in can be distinguished by an internal code, it is possible to replace it with another internal bin-in code design. Table 3 is the Pinyin internal code bulletin. Here, the Pinyin internal code is set in a code area where both upper pits of each byte of the 94x94 code area of the information exchange Chinese character code system consisting of 2 bytes are turned on.

Blank space below> The Chinese input device according to the present invention has the following configuration.

(1) One pinyin is composed of two keys, the initial and the final. The first (odd numbered) key stroke is the final word, and the second (even numbered) key stroke is the final word.

(2) In order to understand all Pinyin as a structure composed of a combination of voice II and final 1, the concept of zero final is established. A zero-voiced initial represents the state of an empty set, and is associated with a specific key. For example, pinyin such as a is generally considered to have a structure of only finals, but in the present invention, pinyin is considered to have a structure of zero finals and finals a, and like other pinyins, 1 binyin is formed by two keystrokes. With this, it is possible to analyze the odd-numbered alphabet keys as the initials and the even-numbered alphabet keys as the finals.

(3) Voice initials (odd numbered keystrokes) English consonant alphabet keys BPMF, DTNL, GKH, JQ
XX ZC8R, WY is the initial B when pressing the odd numbered key.
PMF, DTNL, GKI-(, JQXlZCSR, W
1, ~V and Y, which represent Y, are not treated as +A as finals in terms of Chinese phonology, but 2 in the 1958 "Method Divination" uses W and Y, and these appear as finals. Take. For example, it is written as ``Weng'', and it looks like ``voice mother W''.
The notation interpreted in the structure + final engj is,
Phonologically, it is explained as the structure of only the vowel ueng, so it is possible to design a Pinyin input in the form of "zero vowel + uengj," but in general, it is better to understand the apparent structure of the vowel than to be aware of the phonological structure. The point that seems to be often done is, Mako, technically there are fewer vocal keys than the 26 alphabet keys, so there is more room for key assignments, but there are far more final keys than the 26 alphabet keys, so there is more room for key assignments. From the two points of lack of allowance for allocation,
Similar to the apparent structure, it is designed to be input as ``voice final W ten rhyme final engJ''.

Similarly, for example, the structure "Bin Ying Y Ten Rhyme Mother 0", which is written and input as YO, is phonologically [Zero vowel +
This will be explained as the structure of the final ioJ, but here it is input as "Final Y ten final 0" like the apparent structure.

Among the English consonant letters, V is not used in Pinyin except when writing ethnic minority place names.

When pressing the odd-numbered key, V is substituted with the initial ZH.

The initials C1l and SH are replaced by English vowel letters and initial keys. When the odd numbered key is pressed, it is interpreted as an English vowel letter or vowel key. Substitute the U key for the initial CH, and use the U key for the initial CH.
tt is replaced with the I key.

0 is treated as a zero voice initial.

There are no initials that correspond to the English vowel alphabet keys A and E. Therefore, if both keys are pressed at an odd number, it is considered an input error.

In the above, there are a total of 24 initials.

(4) afl mother (@number-th keystroke) (4,1) The English vowel letter capital key ΔEIOU corresponds to the rhyming final aeiou when pressed at an odd-numbered keystroke.

(4, 2) Consider the frequency of use in the key arrangement for compound finals, and assign efficient key positions to frequently used finals. Also, finals with the same initial letter are placed in close proximity to the same - hand. For example, as follows.

Ai, aQ, and ang that start with a are placed at the key position of a friend's index finger.

ei, en, and eng that start with e are placed on the keys of your friend's index finger and middle finger.

Starting with i, ia, ie, iao, 1u (iou),
ianSiong.

Place in and ing at appropriate key positions on the right hand.

Ou starting with 0 is placed on the left hand key. ong and ion
g is the same key.

Finals starting with U are basically assigned to the left hand.

(43) The number of rhyming finals that can also be used as a different ending far exceeds the vowel keys on an English keyboard, as well as the 26 letters of the alphabet, and is about 1.5
reach double. For this reason, the total number of finals can be calculated as alphabet 2
In order to assign it to the 6 keys, we must establish a principle for Ibun tanzen use in which different endings can be used in the same key.

Combination use with allophones is meaningless unless it also includes the possibility of distinguishing each final based on some kind of information, but in the present invention, this is achieved by using the same key for finals that differ from each other in combination with initials.

The table of possible combinations of polyphonic finals that can also be used as Wu finals is the first one.
Shown in the table.

<Left below> For example, iong can only be combined with 24 finals such as a and ai. Among these combinable finals, for example, if we look at the combinable finals for m, engSongSuSua, ual, ua
The nine finals of ngSue and uiSuo are ion, and the combination overlaps with possible finals. For these 9 finals, the final i
It is possible to use both ong and final m as three finals.

In this way, by searching FIG. 7, it is possible to set combinations of n pinyin that can correspond to l keys.

The keyboard layout shown in Figure 2 is an example of a keyboard design that takes into consideration the frequency and ease of remembering similar pinyin while drawing on this table.

Determination of which of the plurality of finals is required is made by drawing all the pinyin codes corresponding to the keyboard of the keyboard device shown in Table 2.

An example of the combination of different finals shown in the arrangement table of the Pinyin keyboard device in Table 1 is shown below.

The final word ia also serves as ua. ia Hari, JSQ.

Combined with X and Y, ua is G, KSH, ZH, C14,
Since they are spelled together with S I-1 and W, even if ia and ua share the same key, it is possible to identify which final they are by subtracting the leading final.

The final word iong also serves as ong. iong is J, Q.

It's spelled X, Y, long beams, T, N, L, G.

Since KS HlZl-1, CHlR, Z, C, and S are spelled in conjunction, iong and ong can be used as keys, and by subtracting the leading initial, it is possible to specify which finale it is.

The final word O doubles as uo. 0 is BSP, M.

F1 is spelled with zero initial, uO beam, T, N, L.

Since G and H are spelled together, even if 0 and UO are used as keys, it is possible to identify which final the word is by subtracting the leading final. However, l.

is an exception. lO is incorporated into luo.

uai also serves as U. uai is G, ni, H, Zl-1
, CHlSHlW, U is N, L, J, Q, X
, Y, so even if uai and U share the same key, it is possible to identify which finale they are by subtracting the leading final.

ui (uei) also serves as ue. ui (uei) is
D.T.

G, ni11(,Zl-(,CH,SH,R,ZS C,

〜V and ie are spelled together with N, L, J, Q, can be identified.

uan also serves as 1ian. uanhari, T,N.

L, G, K, H, ZH, CH, SH

S and W are spelled together, and jan is spelled J, QSX, and Y. Therefore, even if van and uan are used in the same key, it is possible to specify which finale they are by subtracting the leading initial.

uang also serves as iang. uang to G1, I
-1, Zl(, CHlSH, W, and iang is concatenated with N1LS J, Q, XSY, so uang
Even if ``and iang'' are used in the same key, it is possible to identify which finale it is by subtracting the final vowel.

For example, all compound finals starting with i are not spelled with [zero initial], so finals er, which are only spelled with ``zero initial'',
Can be used together with eSn, ng, and m.

(5) Convert the normal internal code string inputted by the keyboard design on the internal code into Pinyin code. The internal Pinyin code system shown in Table 2 is one example. The internal code system in Table 2 is based on the Bin-in internal code bulletin in Table 3. In the internal Pinyin code system shown in Tables 2, 3, and 4, un is designed to be the same code as jn, and uan is the same code as jan. Furthermore, UE and UE are designed as separate codes. Although designed according to complete Pinyin writing principles, these chord designs are variations on the base system described above. As a result of this internal code design, jue, que
, xue, yue are coded with ue and nje
, lue is coded in ue.

(6) Control circuit Fig. 2 is a block diagram of a system as an embodiment of the present invention.
A screen display device 4 and a printing device 5 are connected to each other.

FIG. 3 shows an algorithm for specifying a pin code by combining input keys, which is implemented in the control device in the embodiment of FIG. 2.

When the control device is set to 5 tarts, the memory of the initial chord is cleared as a first step. The second step is to input data from the keyboard. In the third step, it is determined whether it is the end key, and if YES, the process ends, and if No, the process goes to the fourth step. In the fourth step, it is determined whether the key at the 26th key position of the alphabet has been pressed, and if the answer is No, other processing is performed, and if the answer is YES, the process goes to the fifth step. In the fifth step, it is determined whether the key is a normal odd-numbered key (if the initial chord is memorized), and if YES, the process goes to the sixth step, and if NO, the process goes to the eighth step. The 6th step is A on the English keyboard.
If the answer is YES, an error is displayed, and if the answer is NO, the internal code of the pressed key is stored as the initial code in the seventh step. In the eighth step, the internal code of the pressed key is used as the final code, and is combined with the final code. The 9th step is the initial chord +
Pull the bin-yin keyboard bulletin with the final chord. The 1st O step determines whether there is a pinyin code corresponding to the back of the page, and if no, an error is displayed, and if YES, the corresponding binyin code is stored as a document code in the next 11th step. The final twelfth step clears the memory of the initial chord.

[Effects of the Embodiments] The Chinese input device shown in the above embodiments can produce the following excellent effects.

(1) Easy to remember as it respects the English keyboard layout as much as possible. Most of the vocal finals and the rhyming final aei.

U is the same as the English keyboard layout. In reality, all you need to learn new is the compound final arrangement.

(2) In order to keep the number of keys within 26 keys of the alphabet, a plurality of bin-in elements (initals or initials) are assigned to the same key. Which of the multiple bin-in elements is requested is determined by determining the following conditions. It is a clever design that takes into consideration the pinyin structure.

Odd numbered (voice initial), even numbered (rhyme @).

Which initial is combined with (discrimination of final).

Bin-in elements that are assigned to the same key position are, for example, "iong" and "ong", and "uang" and "
Consideration has been given to grouping similar items together, such as ``iang.'' Therefore, it is easy to remember.

(3) The frequency of key use is taken into consideration. High-frequency keys are arranged in easy-to-press positions.

(4) Voice initial + I? Since it is an input method based on i1, there is no need to distinguish between interval tone code inputs.

(5) Matters to consider The initial m and the final m are in different keys.

Irregular arrangement of dictionary data Since the I key + 0 key takes the combination of luo, the 01 character is arranged in the dictionary using luo instead of io.
