Description

TECHNICAL FIELD The present invention relates to a Chinese input for inputting Chinese (Kanji) from a keyboard on the basis of reading (Pinyin) and its keyboard.

(Prior Art) Conventionally, as a technology in such a field, Japanese Patent Laid-Open No. 61-1821
64, JP 61-275969, JP 62-75757
JP-A-62-145461, JP-A-62-187364, and the like.

In this type of conventional device, as a method of inputting pinyin, there are an all-phoneme input method and a bi-pinyin input method.

The whole phoneme input method is the normal alphabet "a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, excluding v. s, t, u, w, x,
Pinyin of Chinese characters consisting of 36 phoneme combinations (up to 6) represented by "y, z" and unique symbol "", based on one key operation on the keyboard.
It is to input each one.

In addition, the bi-pinyin input method is used for the pinyin of Chinese characters composed of a combination of 26 phonemes described above, and 20 consonants (single consonants) of the 26 phonemes “b, c, d, f, g, h, j, k,
l, m, n, p, q, r, s, t, w, x, y, z "and three consonants (twin consonants) composed of a combination of two consonants of the 26 phonemes. 23 consonants consisting of "ch, sh, zh", and 6 vowels (single vowels) "a, e, i, o, u" of the 26 phonemes and the 26 phonemes Composed of 2 to 4 combinations of
27 vowels (compound vowels) "ai, an, ang, ao, ei, en, eng, ia, ia
n, iang, iao, ie, in, ing, iong, iu, (or iou), ong, ou, u
a, uai, uan, uang, ue, ui, un, uo, e "and decomposed into 33 vowels, and one consonant and one vowel or one vowel is generated based on one key operation on the keyboard. One or two are input.

(Problems to be Solved by the Invention) However, in the conventional device using the above-mentioned all-phoneme input method, only a unique symbol “” is assigned to one of the keys of a normal keyboard provided with an alphabet and used as it is. Moreover, a person skilled in the arrangement of the alphabet on the keyboard can immediately perform the input operation, but a maximum of 6 key operations are required for one kanji, making it difficult to increase the input speed. there were.

In addition, in the conventional device using the above-mentioned bi-pinyin input method, if a keyboard having keys corresponding to the above-mentioned 23 consonants and 33 vowels respectively is used, the pinyin corresponding to one kanji is performed twice. Although it is possible to input by key operation of, the special keyboard makes it difficult for non-experts to input efficiently, and one key can be used to input other phonemes, such as compound vowels, on a normal keyboard. It is also possible to use a keyboard that assigns this by the shift key, but in this case, the shift key is operated frequently, and the original advantage that pinyin corresponding to one kanji can be input by two key operations Did not make use of.

Furthermore, the conventional device has a problem that a word composed of a combination of a plurality of Chinese characters cannot be efficiently input.

The present invention solves the above-mentioned problems, does not require the operation of the shift key at all, and is the same as a normal alphabet.
It is only necessary to operate individual keys, a high-speed input device is possible, and a Chinese input device that allows beginners to operate efficiently is also provided, and Chinese words can be input efficiently. To provide a simple Chinese input device.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a Chinese input device for inputting Chinese (Kanji) from a keyboard on the basis of reading (Pinyin), and consonants that constitute Pinyin of Kanji and 6 single vowels are assigned to alphabet keys, twin consonants are redundantly assigned to keys to which single vowels that do not come at the beginning of Pinyin are assigned, and for compound vowels, the consonant immediately preceding the same key to which the consonant is assigned A keyboard in which only compound vowels having exclusivity to the connection with and are assigned to each other, and a compound vowel other than the compound vowel is assigned to a key other than the key to which a consonant is assigned, and a consonant and a single vowel that constitute Pinyin Is generated by the operation of one key, and the vowels that compose the remaining Pinyin are one key operation or the key to which a single vowel is assigned and the key to which another vowel is assigned. It is generated by the operation of two keys, and when the key to which consonants and vowels are assigned in Pinyin input is operated first, the corresponding consonant is generated, and when it is operated second or later, a vowel is generated. And 2 for the second operated key
When the above vowels are assigned, key data conversion means that generates a vowel that can be connected to the immediately preceding consonant among the corresponding vowels, a single kanji dictionary that stores a large number of kanji in correspondence with its pinyin, and a key from the keyboard. Searching means for searching a single kanji dictionary for kanji corresponding to pinyin of kanji input via the data converting means; first storing means for storing the kanji searched by the searching means as input candidate kanji;
Selection means for selecting one of the input candidate kanji based on information such as numbers input from the keyboard, and storing the selected kanji of the input candidate kanji as the input kanji
And a display control means for displaying the input candidate kanji and the input kanji in respective predetermined areas of the display device.

Further, according to the present invention, a single kanji dictionary storing a large number of kanji characters corresponding to its pinyin so that either a single kanji character or a word can be input, and a word having a character number of "2" are the first.
Letter consonant, first letter vowel, second letter consonant and second
Each key code that specifies a vowel of a letter is assigned, and for a word with the number of characters "3", the consonant of the first character, the consonant of the second character, the consonant of the third character, and the vowel of the third character are designated. Assign the key code of
For words with a character count of "4", the consonant of the first letter,
The keys of the keys for designating the consonant of the second character, the consonant of the third character, and the consonant of the fourth character are assigned, and for words having a number of characters "5" or more, the consonant of the first character and the consonant of the second character are also assigned. , By assigning the code of each key that specifies the consonant of the third character and the consonant of the last character, a word dictionary composed of four key codes is used as an index, and a word dictionary that stores a large number of words and a predetermined key input An input discriminating means for discriminating whether the input from the keyboard is for single-kanji input or for word input based on
Based on the discrimination result of the input discrimination means, a kanji search means for retrieving a kanji corresponding to Pinyin input from the keyboard from a single kanji dictionary, and designated by four key inputs from the keyboard based on the discrimination result of the input discrimination means. Word search means for searching a word corresponding to the word code from a word dictionary, and first storage means for storing the kanji or words searched by the kanji search means or word search means as input candidate kanji or input candidate words. And a selection means for selecting an input candidate kanji or one kanji or word in the input candidates based on information such as kanji input from the keyboard, and an input candidate kanji or a selected kanji or word in the input candidate words. Second storage means for storing as input Chinese characters or input words, input candidate Chinese characters or input candidate words and display Chinese characters or input words It is provided a display control means for displaying each of a predetermined area.

(Operation) According to the first Chinese input device of the present invention, in order to input Pinyin of a Chinese character from the keyboard, for example, when a key to which one consonant constituting the Pinyin is assigned is operated,
Regardless of the vowel assigned to the key, the consonant is generated by the key data converting means, and when the vowel following the consonant is operated, the key is assigned to the consonant assigned to the key or another vowel. Instead, the key data converting means generates the vowel, and the searching means searches the single kanji dictionary for the kanji corresponding to the Pinyin composed of the child and the vowel. This is stored in the first storage means as the input candidate kanji. It is stored and further displayed in a predetermined area of the display device by the display control means. Here, if there is a Kanji to be input in the displayed Kanji and information such as numbers for selecting the Kanji is input from the keyboard, the corresponding Kanji among the input candidate Kanji is selected by the selection means, and this The input kanji is stored in the second storage means and is displayed in another predetermined area of the display device by the display control means. Also, if there is no Kanji to be entered in the displayed Kanji and the information requesting the display of the next input candidate Kanji is entered from the keyboard, the next input candidate Kanji is retrieved from the single Kanji dictionary by the selection means. Then, this is stored in the first storage means in the same manner as described above, and thereafter processed in the same manner as described above.

Further, according to the second Chinese input device, since a word is input from the keyboard, when a specific code or the like is input,
This is detected by the input determination means, and then the corresponding word is searched from the word dictionary by the word search means from the code based on the Chinese pinyin input from the keyboard, and this is stored as the input candidate word in the first storage means, Hereinafter, it is processed in the same manner as in the case of Kanji in the first device, and when the Pinyin of the Kanji is input from the keyboard without inputting the above-mentioned specific code, the Kanji search means is based on the Pinyin. The corresponding Chinese character is searched from the single Chinese character dictionary, this is stored as the input candidate Chinese character in the first storage means, and thereafter, the same processing as in the case of the first device is performed.

(Embodiment) FIG. 1 shows an outline of a Chinese input device of the present invention. In the figure, a is a keyboard, b is key data conversion means, and
c is a single-kanji dictionary, d is search means, e and f are first and second storage means, g is selection means, h is display control means, and i is a display device.

The keyboard a is the same as the keyboard for inputting alphabets and has 26 keys and 23 consonants that make up the Pinyin of the Chinese character are assigned to different keys, and the consonant immediately before the 33 vowels that make up the Pinyin of the Chinese character is assigned. The 33 vowels are assigned, including the key to which the consonant is assigned, so that only the vowels having exclusivity with respect to the connection with are overlapped.

The key data conversion means b generates a corresponding consonant when the key assigned the consonant as the first operation key in the keyboard a is operated, and operates the key assigned the consonant as the second operation key. Generates a vowel that can be connected to the immediately preceding consonant among the corresponding vowels, and generates a corresponding vowel when the key to which the consonant is assigned as the third operation key is operated, and corresponds in other cases. It produces a vowel that sounds.

The single-kanji dictionary c stores a large number of kanji (about 6,700 words) normally used in Chinese in association with its pinyin.

The search means d is from the keyboard a to the key data conversion means b
A single kanji dictionary c is searched for a kanji corresponding to the pinyin of the kanji input via.

The first storage means e stores the kanji searched by the search means d as an input candidate kanji, and the second storage means f.
Stores the selected kanji in the input candidate kanji as the input kanji.

The selecting means g selects one kanji character among the input candidate kanji characters based on information such as numbers input from the keyboard a.

The display control means h displays the input candidate kanji and the input kanji in respective predetermined areas of the display device i.

Further, FIG. 2 shows an outline of another Chinese input device of the present invention. In the figure, the same components as in FIG. 1 are represented by the same symbols. That is, c is a single kanji dictionary, e and f are the first
And second storage means, g is selection means, h is display control means, i is a display device, j is a keyboard, k is a word dictionary, l
Is an input discrimination means, m is a kanji search means, and n is a word search means.

If the keyboard j can input Kanji pinyin,
Any configuration may be used.

The word dictionary k stores a large number of words in association with predetermined consonants of all Pinyin consonants and vowels of the kanji and vowels or word codes based only on consonants.

The input discriminating means 1 discriminates whether the Pinyin input from the keyboard j is for Chinese character input or for word input.

If the pinyin of the kanji input from the keyboard j is for kanji input, the kanji search means m searches the corresponding kanji from the single kanji dictionary c and the word search means n.
If the Chinese kanji pinyin input from the keyboard j is for word input, the word dictionary k is searched for the word corresponding to the word code based on this.

The kanji search means l is substantially the same as the above-mentioned search means d.

FIGS. 3 to 12 show an embodiment of the Chinese input device of the present invention. Here, an embodiment including all the configurations described with reference to FIGS. 1 and 2 is shown.

FIG. 3 shows the hardware configuration of this embodiment.
In the figure, 1 is a keyboard, 2 is a memory, 3 is a floppy disk drive (FDD), 4 is a display device, 5 is a printer, and 6 is a microprocessor (CPU).

FIG. 4 shows an example of the key arrangement of the keyboard 1 corresponding to the above-mentioned keyboard a. The 23 keys that constitute the above-mentioned Pinyin (Chinese reading) are provided on the keyboard provided with the alphabet arrangement according to the well-known JIS plan. Consonants, 33 vowels, and 15 types of identification code “11” to be described later
"53" is assigned.

Here, among the consonants and vowels that make up Pinyin, 20 single consonants that are common to the alphabet, namely, "b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y, z "and 5
The individual single vowels, that is, "a, e, i, o, u" are assigned according to the JIS arrangement, the remaining single vowels "" are assigned to "V" that are not used in Pinyin, and the twin consonants "ch , sh, z
“H” is assigned to three single vowels “i, u, (v)” that do not come at the beginning of Pinyin among the six single vowels.

In addition, for 27 reconstructed vowels, vowels that have exclusivity to the connection with the immediately preceding consonant are assigned to 23 keys to which consonants are assigned, here, “ong” and “iong”, “iang” and “uan”.
g ”,“ en ”and“ ia ”“ uai ”and“ iao ”,“ u ”and“ u ”
Only "a", "e", "ue", and "ui" are assigned to the same key in duplicate, and compound vowels that can be connected to a single vowel to compose another vowel, that is, "ai, an, ao, “Ang, ong” and three-character single vowels that cannot be configured by connecting a single vowel to another compound vowel, that is, “eng, ing”, are assigned to a position easy for the operator to remember, that is, near the home position.

In the keyboard 1 described above, two or more consonants and vowels are assigned to one key, except for keys assigned single vowels "a, e, o". When one key is operated, Information recognized by CPU6 based on key operation (key data)
Must be uniquely defined.

In general, the kanji pinyin is "consonant + vowel", "vowel"
There are three combinations of "vowel + vowel", but the number of pinyins consisting only of vowels is small, and not all vowels constitute the pinyin of the above-mentioned combination. When is composed of "consonant + vowel", the vowel does not come before the consonant. Therefore,
When the key assigned the consonant is operated first, the key data of the corresponding consonant is generated, and when the key assigned the consonant is operated subsequently, it is assigned to that key as the second key data. Generated vowels.

By the way, according to the “Chinese Pinyin Scheme”, there is a fixed rule for combining consonants and vowels, and not all consonants are combined with all vowels. For example, the consonant "g"
Combines with the vowel "iang" but not with the vowel "uang", and consonant "h" with the vowel "uang" but not with the vowel "iang". That is, the vowel "" uan
There is exclusivity between "g" and "iang" for the connection with the immediately preceding consonant.

In the keyboard 1, since two or more vowels are assigned to one key so that only the vowels having the exclusivity described above overlap, it is checked in advance whether or not each vowel can be connected to each consonant. By storing this in a table, when a key assigned with two or more vowels is operated second, the vowels to be generated as key data can be uniquely determined.

FIG. 5 shows the above-mentioned table, in which the horizontal axis shows the consonant input as the first key data (however, the first cell shows the case where no consonant is input), and the vertical axis shows the consonant. The vowels input as the second key data are represented respectively, and in the figure, the combinations marked with a circle show the connectable combinations.

Note that when inputting Pinyin composed of a combination of "vowel + vowel" or "vowel", for example, when inputting a vowel in a key to which a consonant and a vowel are assigned, the key is operated and then a single Kanji character described later is entered. By operating the conversion request key of
The process is distinguished from the case described above.

By using the keyboard 1 described above, it is possible to input the pinyin of all Chinese characters composed of up to 6 phonemes by operating the keys up to 3 times.

That is, a pinyin consisting of three or less phonemes is operated by operating a key according to the pinyin, or by operating a key to which a consonant constituting the pinyin is assigned, and a compound vowel following this is converted to a compound vowel. A pinyin consisting of four or more phonemes is operated by operating the assigned key, and the key to which the consonant constituting the pinyin is assigned is operated, and the subsequent compound vowel is assigned to the compound vowel. Input by operating a key or by decomposing the compound vowel into a single vowel and another compound vowel and operating the key to which the single vowel is assigned and the key to which the other compound vowel is assigned. Yes (however, for twin sounds "ch, sh, zh", 1
It shall be regarded as an individual phoneme. ).

The Kanji pinyin input method is the same as the conventional all-phoneme input method (however, the input method of twin consonants "ch, sh, zh" is excluded), and the consonants and vowels that make up the pinyin The method of inputting each with one key, that is, inputting with a total of two key operations is the same as the conventional twin pinyin input method. Furthermore, a consonant that constitutes Pinyin is input with one key, and a compound vowel that constitutes Pinyin is input with two keys corresponding to a single vowel and another compound vowel, that is, a total of three key operations. The method of inputting in is a novel input method proposed in the present invention, and hereinafter, this will be referred to as a mixed pinyin input method.

FIG. 6 shows an example of inputting pinyin of Chinese characters by the above-mentioned three input methods. For example, the Chinese character "state" has a pinyin "tai" consisting of three phonemes. However, when this is input by the whole phoneme input method, it is executed by sequentially operating the three keys to which the individual phonemes “t”, “a”, and “i” are respectively assigned. When inputting with, it is executed by operating the key to which the phoneme "t" is assigned, and then operating the "s" key to which the phoneme (compound vowel) "ai" is assigned (mixed It cannot be entered by the Pinyin input method.)

In addition, the Chinese character "like" consists of six phonemes, "zhua
It has a pinyin called "ng", but if you want to enter it with the mixed pinyin input method, operate the "v" key to which the phoneme (twin consonant) "zh" is assigned, and then the phoneme called "u". Operate the key assigned to
This is executed by operating the "g" key to which the phoneme "g" (compound vowel) is assigned. Also, when inputting by the twin pinyin input method, the phoneme "twin" is assigned as in the above. "V" key, then "uang"
This is executed by operating the "l" key to which the phoneme (compound vowel) is assigned (note that since it consists of four or more phonemes, it cannot be input by the whole phoneme input method).

In the above-mentioned bi-pinyin input method, it is necessary to remember all the positions of the keys to which 27 compound vowels are assigned, but according to the mixed pinyin input method, 7 compound vowels near the home position are assigned. Since it is sufficient to remember the key positions, even a beginner can efficiently input.

The display device 4 corresponds to the above-mentioned display device i, the memory 2 is set with the storage areas corresponding to the above-mentioned first and second storage means e and f, and the FDD 3 is also described above. A floppy disk (not shown) in which the single-kanji dictionary c, the word dictionary k, and the operation program (including the above-described table) of this apparatus are stored in advance is inserted. Also,
The program and the CPU 6 realize the key data conversion means b, the search means d (Chinese character search means m), the selection means g, the display control means h, the input discrimination means 1 and the word search means n.

FIG. 7 shows the schematic structure of the single-kanji dictionary according to this embodiment. The master index 11 and the high-frequency character table are shown in FIG.
It consists of 12, sub-index 13 and data section 14.

The master index 11 has the above-mentioned 23 consonants and 6
Of the single vowels, the three vowels "a, e, o" at the head of the pinyin are stored with different relative numbers (addresses). The high-frequency character table 12 is used most frequently among the above-described 23 consonants and three vowels (hereinafter, referred to as the first character) among the Chinese characters with pinyin that starts with one character. 10 kanji mentioned above
Twenty-three consonants and three vowels, that is, for each head character, are stored corresponding to the relative numbers. In addition, in the data section 14, a large number of Chinese characters with identification codes are attached to the pinyin (about 40
It is stored as a set for each Chinese character with the same (0 types). Further, the sub-index 13 has the head position (address) and the number of data of each set in the data part 14 together with each pinyin (however, in the above-mentioned all-phoneme input method, mixed pinyin input method, and bi-pinyin input method, the same pinyin Is input with different key data, it is stored together with pinyin by all the key data. In the data unit 14, the kanji in each set are stored in the order of frequency of use based on the "Chinese Contemporary Kanji Frequencies Dictionary".

FIG. 8 shows an example of the identification code, which is the first stroke drawn (hereinafter referred to as the first stroke), here “-”.
(Horizontal) ”,“ | (vertical) ”, 15 combinations from 5 types of "B (curved)" and the arrangement of the elements that make up the character (hereinafter referred to as "character type"), here 3 types of "left and right", "up and down", and "other" The types of codes “11” to “53” are configured.

The identification codes "11" to "53" are located on the keyboard 1 where the frequently used identification code (the smaller the numerical value indicating the code, the more frequently used) is located at a position where it can be easily operated as shown in FIG. Assigned as follows. It should be noted that the identification code input and the pinyin input are distinguished from each other by the difference in the single Kanji conversion request key input after the operation, as described later.

FIG. 9 shows how word codes are added in the present embodiment, and is constituted by a fixed number, here four codes, regardless of the number of characters. That is, the number of characters is "2"
For the word, the consonant of the first character, the vowel of the first character, the consonant of the second character and the vowel of the second character are used as the first, second, third and fourth codes, respectively, and the number of characters is "3". Similarly, for the word, the consonant of the first letter, the consonant of the second letter,
The consonant of the third character and the vowel of the third character are used respectively, and for the word with the number of characters "4", the consonant of the first character, the consonant of the second character, the consonant of the third character, and the consonant of the fourth character are also used. For each word having a character number of "5" or more, the consonant of the first character, the consonant of the second character, the consonant of the third character, and the consonant of the last character are also used.

The input of each code is performed by the twin pinyin input method in the above-mentioned single kanji input, but the distinction from the single kanji input is made by inputting its identification code, here, ";(semicolon)", as described later. It depends on whether or not.

Note that here, unlike the case of single kanji input, the consonant is 2
Since there are cases where more than one consecutive consonant or vowel is input, it is not guaranteed that the CPU6 will correctly recognize the consonant or vowel. Therefore, the above-mentioned code actually uses the alphabet itself. Sometimes the same code is attached to a completely different word.)

FIG. 10 shows a schematic structure of the word dictionary in this embodiment. In the figure, 21 is a master index, 22 is a sub index, and 23 is a data part.

The data section 23 has a large number of data in which the word code consisting of the above-mentioned four codes (actually the alphabet) and the set of words corresponding to this are one unit (the data amount is variable), in the code order, that is, the alphabet. Although stored in order, the data section 23 is composed of a large number of blocks containing the data in a fixed amount. In the sub index 22, a word code corresponding to the data stored at the end of each block is stored together with a relative number (address) indicating each block. In addition, the master index 21 uses the relative numbers (addresses) of the word codes, which are the first codes of the word codes stored in the sub-index 22 and each of which has the first 26 letters of the alphabet, as the first code. I remember with.

FIGS. 11 (a) and 11 (b) show the flow of the operation program for word input in this embodiment, and the operation will be described below according to this.

First, when a key input occurs on the keyboard 1 (steps sp1 and sp2), the CPU 6 checks whether or not the key data is ";" (step sp3), and if it is not ";", determines that it is the single kanji input mode. The processing described later is executed, and if it is ";", it is determined to be the word input mode, and the alphabet code generated based on the subsequent key input is received without conversion (step sp4,
sp5).

Receive the code for 4 characters (step sp6)
Then, the CPU 6 searches the master index 21 of the word dictionary with the first code (step sp7), and further searches the sub index 22 based on the relative number attached to this,
The word code that is rearward in the alphabetical order from the received word code is extracted (step sp8), and the data portion 23 is further calculated based on the relative number attached to the word code.
And retrieve the top 10 words from the set of words in the data with the received word code (step
sp9), these are stored in a predetermined storage area of the memory 2, and are displayed with numbers in predetermined areas of the display device 4 (step sp10).

At this time, the word to be input is displayed on the display device 4, and a key input for selecting the corresponding word from the keyboard 1, for example, a numeric key corresponding to the number given to the corresponding word (or selection confirmation together with this) is performed. When the CPU 6 stores the corresponding word in another storage area of the memory 2, that is, the actual data input area, and the predetermined value of the display device 4 is input. In another area (step sp14).

Further, the kanji to be input is not displayed on the display device 4, and a key for requesting the display of the next ten words corresponding to the word code from the keyboard 1, for example, the next screen (or next candidate) key When input (step sp15),
The CPU 6 fetches the next one word from the corresponding set in the data section 23 (step sp16), and stores these words in the memory 2 as described above.
, And display it on the display device 4.

FIGS. 12 (a), (b) and (c) show the flow of the operation program for inputting single Chinese characters in the present embodiment, and the operation will be described below according to this.

As described above, if the key data input first is not “;”, the alphabet code generated based on the subsequent key input is converted based on the above-mentioned table and recognized by the CPU 6, Hereinafter, this point will not be described in detail.

That is, the keyboard 1 is operated. (Steps s1, s
2), the CPU 6 checks whether or not the first input key is the first character of Pinyin (step s3), and if it is the first character, the same character as that character is used as the master index 11 in the single-kanji dictionary.
Further, it retrieves (step s4) and, based on the relative number attached to it, retrieves the corresponding 10 wide-frequency characters from the high-frequency character table 12 (switch s5) and stores them in a predetermined storage area of the memory 2. It is stored and displayed in a predetermined area of the display device 4 with a number (step sp6).

At this time, when the kanji to be input is displayed on the display device 4 and the numeric key or the like for selecting the corresponding kanji is input from the keyboard 1 (steps s7, s8, s9), the CPU 6 selects the corresponding kanji. The data is stored in the actual data input area of the memory 2 and displayed in another predetermined area of the display device 4 (step s10).

On the other hand, if there is no Kanji to be input in the high frequency characters, Pinyin will be continuously input from the keyboard 1 (steps s11, s12), but it will indicate the end of Pinyin input and request conversion to Kanji. When a key indicating, for example, the space key is input (step s13), the CPU 6 searches the single Kanji dictionary sub-index 13 for the same pinyin that has been input so far (step s1).
4), based on the address attached to this, from the data part 14 to the beginning of the set of kanji corresponding to the pinyin
The ten Chinese characters are taken out (step s15), these are stored in a predetermined storage area of the memory 2, and the numbers are displayed in predetermined areas of the display device 4 (step s16).

At this time, when the kanji to be input is displayed on the display device 4 and a numeric key or the like for selecting the corresponding kanji is input from the keyboard 1 (steps s17, s18, s19), the CPU
6 stores the corresponding Chinese character in the data input area of Momeri 2 and displays it in another area of the display device 4 (step s2
0), and the corresponding Kanji in the data section 14 of the single Kanji dictionary is rearranged so as to be the head of the set of homophone meaning words (step s21).

Further, the kanji to be input is not displayed on the display device 4, and the next screen (or next candidate) key for requesting the display of the next ten kanji corresponding to the pinyin is input from the keyboard 1 ( Step s22) and the CPU 6
Then, the next 10 Chinese characters are extracted from the corresponding set (step s23), and these are stored in the memory and displayed on the display device 4 as described above.

On the other hand, a key indicating the end of pinyin input and the input of an identification code and a request to convert to kanji, for example, a "]" (key bracket) key is input, or four key data are input (step s24). ), And the CPU 6 uses the data excluding the identification code input last among the data input so far as the pinyin of kanji (in this device, the pinyin of kanji is input by a maximum of three key input operations). Therefore, the data of the 4th key is identified as the identification code.) This Pinyin is the sub index 13 of the single Kanji dictionary.
(Step s25), and further, based on the address attached to this, from the set of kanji corresponding to the Pinyin from the data part 14, the first 10 identification codes having the same identification code as the input identification code Extract Kanji (Step
s26), these are stored in a predetermined storage area of the memory 2 and are displayed with numbers in predetermined areas of the display device 4 (step s27).

At this time, when the kanji to be input is displayed on the display device 4 and a numeric key or the like for selecting the corresponding kanji is input from the keyboard 1 (steps s28, s29, s30), the CPU
6 stores the corresponding Chinese character in the data input area of Momeri 2 and displays it on another area of the display device 4 (step s3
Together with 1), the corresponding kanji in the data part 14 of the single kanji dictionary is rearranged so as to be the head of the set of homonyms (step s21).

Further, the kanji to be input is not displayed on the display device 4, and the next screen (or next candidate) key is input from the keyboard 1 to request the display of the next ten kanji corresponding to the Pinyin (step s32), the CPU 6 retrieves the next 10 Kanji characters having the identification code from the corresponding set of the data section 14 (step s33), stores them in the memory 2 and displays them on the display device 4 in the same manner as described above. .

(Effects of the Invention) As described above, according to the present invention, the keyboard of a keyboard to which consonants and vowels that constitute Pinyin of Chinese characters are assigned
All the consonants or vowels to be input can be uniquely input by operating only one key, so the Pinyin can be input efficiently and at high speed, and the number of key operations is small. Even beginners can input efficiently. Further, according to the device for inputting a word using the word code based on Pinyin, it is possible to input a word of two characters or more accurately and efficiently. Also, according to the keyboard of the present invention, 23 consonants and 33
Pinyin of 56 Chinese characters consisting of vowels can be assigned to 26 keys similar to the alphabet, and in general, it is only necessary to assign predetermined keys to the keyboard, and pinyin without the need for shift operation etc. There is an advantage that unique key data can be obtained according to the above method.
