DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Tibetan input device for inputting a Tibetan word and converting it into Tibetan characters by input means such as a keyboard having a plurality of keys. More specifically, the present invention refers to a measure for efficiently inputting a syllable representing Tibetan with a small number of keys and a small number of keystrokes.

[0002]

2. Description of the Related Art Before describing the prior art relating to Tibetan input, first, Tibetan and Tibetan characters will be described. In the following description, a consonant or consonant group at the beginning of each syllable in Tibetan is called an initial, and a vowel or consonant following the initial is called a final. Further, a tone (pitch) when a syllable is pronounced is called a tone.

[0003] Tibetan characters are phonograms, but have a long history, and when comparing ancient and modern languages, the spelling of words has not changed much since the 9th century, It can be seen that there is a large difference.
In other words, the ancient language should have been pronounced exactly as it was spelled, but in modern languages, the spelling of letters is quite different from the actual pronunciation. Furthermore, there are several dialects of modern languages, and words with the same spelling are read differently in each dialect.

[0004] The modern Tibetan phonological system described below is an example of a phonological system based on Lhasa sounds. One syllable in modern Tibetan is composed of one kind of initial, one kind of final, and one kind of tone combination. In addition,
Here, it is assumed that there is a zero vowel as one type of vowel.

It is assumed that 30 consonant characters as shown in Table 1 below and four vowel symbols as shown in Table 2 are present in Tibetan characters.

[0006]

[Table 1]

[0007]

[Table 2]

The information represented by each of the modern Tibetan consonants includes a final a and a tone other than the initial.
That is, each of the 30 consonant characters shown in Table 1 represents one syllable. In the transcription of the consonant characters shown in Table 1 in Roman alphabet, a symbol representing the tone is added after the final a. Table 1 shows two kinds of tone symbols. Of these tones, H represents a high tone with a high tone, and L represents a low tone with a low tone.

It should be noted that the number of Tibetan syllables is not only 30. For example, the first configuration example of the Tibetan character shown in FIG. 26 and FIG.
In the configuration example, the syllables other than 30 syllables Sy represented only by each consonant character are represented. Here, the syllable Sy is displayed by using up to six consonant characters, one vowel symbol, and one syllable end symbol. In each of FIGS. 26 and 27, the vowel symbol is E
And consonant characters at other positions. The last position of the two types of Tibetan characters Ch in FIG. 26 and FIG. 27 is a syllable end symbol “′” indicating that the syllable has ended (originally, FIG. 26 and FIG. 27).
The inverted triangle symbol displayed at the last position of the syllable Sy should be described in the specification, but the current electronic filing system limits the symbols that can be used. To represent the syllable end symbol)
Is written.

Of the letters and symbols A to G shown in FIGS. 26 and 27, C is the center, and the other letters and symbols may be considered to modify C. Phonologically, C
Represents a basic consonant (basic consonant letter), and A and B
Is a pre-consonant that comes before the letter C (pre-consonant letter)
, The letter D represents the post-consonant (post-consonant letter) following the letter C, the symbol E represents the main vowel (primary vowel symbol), and the letters F and G represent the ending (ending). Character). More specifically, the letters A, B, and D serve to represent changes in the initial and tonality (tone, ie, low or high accent), and E, F
The letters and symbols of G and G have a role to represent a change in the final and a change in tone (whether the accent is lowered or not).

The conventional Tibetan input device assigns 30 consonant characters, 4 vowel symbols, and other symbols in Tibetan language to keys on a keyboard, and maps these characters and symbols. 26, and keys A, B, C, D, E, F, G and 'shown in FIG. 27, respectively, to complete the input of the Tibetan character string Ch representing one syllable. Therefore, in the conventional Tibetan input device,
In order to input a Tibetan character string Ch representing one syllable, it is necessary to perform eight keystrokes at most.

[0012]

As described above, in the conventional Tibetan input device, a minimum of two keystrokes (C + 'shown in FIGS. 26 and 27) are required to input a Tibetan character string representing one syllable. , A key operation of up to eight keystrokes is required. For this reason, considering the average number of keystrokes,
A relatively large number of keystrokes are required to input each syllable in Tibetan, causing a problem that the usability of the Tibetan input device is poor.

On the other hand, in modern Tibetan, there are cases where different Tibetan character strings have the same reading, and in particular, in a syllable word, there is a disadvantage that homonyms are often seen. Therefore, it is required to select a Tibetan character string that represents a necessary word faster and more easily from a plurality of homophones corresponding to the input reading.

[0014] Furthermore, there may be a case where it is desired to input characters and character strings for ancient Tibetan which are no longer used in modern Tibetan, and these characters and character strings for ancient Tibetan can be easily input. You will need a means of input. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has a small number of keys of input means such as a keyboard and a key stroke number as small as possible to efficiently input a Tibetan word, thereby providing a user-friendly Tibet. It is a first object to provide a word input device.

Further, the present invention provides a Tibetan input device capable of selecting a Tibetan character string representing a required word faster and more easily from homophones corresponding to input Tibetan readings. The second object is to provide Furthermore, the present invention can easily input these ancient Tibetan characters and character strings when inputting ancient Tibetan characters and character strings that are no longer used in modern Tibetan. It is a third object of the present invention to provide a Tibetan input device that can perform the input.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a Tibetan input device 1 based on the first principle of the present invention, first, a first reading code corresponding to a first reading code and a second reading code corresponding to a second reading code constituting a reading of Tibetan language, respectively. A key composed of a reading code input section and a second reading code input section is arranged on input means such as a keyboard. Preferably, the first reading code constituting the Tibetan reading is a Tibetan initial, and the second reading code is a Tibetan final.

Further, all the syllables of the Tibetan language are input by the independent operation of the first reading code input section and the second reading code input section in the units of the first reading code and the second reading code, respectively. Therefore, when inputting all the syllables of the modern Tibetan language by keying the above keys, the number of times of keying can be reduced to two times, so that the Tibetan language input method is much more efficient than the conventional Tibetan input method. Can be input.

Here, it should be noted that, generally speaking, if the number of keystrokes is greatly reduced, the number of keys used for keystroke input will be greatly increased. However,
In the Tibetan input device based on the first principle of the present invention,
Second, a key consisting of a first reading code input section and a second reading code input section is arranged at the same place in the input means, and the first reading code input mode and the second reading code input mode are automatically switched. To switch to. With such a configuration, the number of keys used for keying input is reduced to the same degree (slightly reduced) as in the case of conventional Tibetan input, although the number of keystrokes is reduced in the first configuration. ) Can be suppressed.

More specifically, in the Tibetan input device based on the first principle of the present invention, all syllables of the modern Tibetan language can be input with two keystrokes, and the input of Tibetan syllables can be performed. The number of keys on the keyboard to be used can be reduced to a total of 30 or less in three steps (excluding keys operated by the thumb). Therefore, it is possible to efficiently input a Tibetan word with a small number of keystrokes and a small number of keys, and to provide a user-friendly Tibetan input device.

Further, in the Tibetan input device based on the first principle of the present invention, thirdly, the syllable terminating symbol which must be input at the end of each syllable in the conventional Tibetan input device, Since the function of automatically adding a syllable without user input is realized, the input efficiency of each syllable in Tibetan can be further improved. Fourth, in the Tibetan input device based on the first principle of the present invention, fourthly, when converting the Tibetan reading into Tibetan characters and displaying the Tibetan reading on character display means or the like, the first reading code and the first reading code are used. Uses different colors or luminances so that the two-reading codes are distinguished from each other, so that the first reading code (eg, the initial) and syllable indications that can be confused or misunderstood are clearly distinguished can do.

Furthermore, in the Tibetan input device based on the first principle of the present invention, fifthly, the user inputs the first reading code or the second reading code constituting each syllable reading of Tibetan. After that, without having to press a key (conversion key means) for reading code / character code conversion on the keyboard, the most frequently used Tibetan character among Tibetan characters representing the syllable (ie, the most common term) Because the function that can be automatically converted to syllables is realized, the most common term of each syllable can be obtained faster and more reliably.

Further, in the Tibetan input device based on the first principle of the present invention, sixthly, the key is automatically converted immediately after a key composed of the first reading code input section and the second reading code input section is pressed. First reading code (eg, voice)
Since a function that can be arbitrarily specified by the user with respect to Tibetan characters representing syllables and syllables is realized, the most common term that each user wants to use can be obtained faster and more reliably.

Furthermore, in the Tibetan input device based on the first principle of the present invention, seventhly, when a word of one syllable or a word of a plurality of syllables includes plural kinds of homonyms, a word of one syllable is used. Alternatively, a key composed of a single syllable word conversion key means, a double syllable word conversion key means and a word selection key means is arranged so as to select one word from words of a plurality of syllables. Words and polysyllabic words can be obtained faster.

On the other hand, in the Tibetan input device based on the second principle of the present invention, first, each syllable is decomposed into a character string composed of three or less character parts in consideration of the reading of Tibetan. Then, a key comprising a character string input unit for inputting Tibetan words in units of these character parts is arranged on input means such as a keyboard. Preferably, the character part constituting the Tibetan character string is a Tibetan prefix consonant character,
There are three units: basic consonant characters and post-consonant characters, and main vowel symbols and suffix characters.

Further, by hitting a key composed of the character string input section, a character string composed of three unit character parts is input and converted into a corresponding Tibetan character code. Therefore, the number of keystrokes when inputting the Tibetan character string representing all the syllables of the modern Tibetan language by operating the above keys can be suppressed to within three times, which is far more than the conventional Tibetan input method. It is possible to input each syllable in Tibetan efficiently.

Furthermore, the Tibetan input device based on the second principle of the present invention is secondly provided with a spelling conversion instructing unit for instructing conversion from modern Tibetan spelling to ancient Tibetan spelling. The keys are arranged on input means such as a keyboard. In this case, a Tibetan character or string that is not used in modern Tibetan is considered an allograph (ie, the ancient Tibetan spelling) and its orthography (ie,
By operating the above keys after inputting a modern Tibetan spelling), it is also possible to easily input these variants.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings (FIGS. 3 to 25). FIG. 3 is a block diagram showing a configuration of an embodiment based on the first principle configuration of the present invention. Here, the configuration of the Tibetan input device 1 for realizing the first principle configuration shown in FIG. 1 will be described in detail. Hereinafter, the same components as those described above will be denoted by the same reference numerals.

In describing an embodiment based on the first principle configuration of the present invention (hereinafter abbreviated as the first embodiment),
First, we classify Tibetan phonemes in a unique format. There are 61 types of modern Tibetan speakers, as shown in Tables 3, 4 and 5 below.

[0039]

[Table 3]

[0040]

[Table 4]

[0041]

[Table 5]

In general, Lhasa vowels are classified into about thirty, but in this case, the tone information is included in the Tibetan consonants, and the high and low tones are generated when the vowel is pronounced. Taking into account that there is a distinction from a tone, a high or low tone is generally added to a vowel. Furthermore, in order to make it easier to organize a total of 61 types of vowels,
The vowel is a harmonic (H) monophonic consonant, a low tone (L) monophonic consonant,
It is divided into five groups: harmonic monophonic consonants, low harmonic monophonic consonants, and low harmonic double consonants.

On the other hand, the modern Tibetan rhyme is
There are 57 types shown in Tables 6 and 7 below.

[0044]

[Table 6]

[0045]

[Table 7]

Since a character string representing a modern Tibetan word contains information indicating whether a tone is to be extended flat or lowered, a flat or descending phrase is generally referred to as a rhyme. The final tone is classified by adding the tone (plain tone or tone). In addition, in the Roman alphabet transcription of the final element shown in Tables 6 and 7, the symbol indicating the tone is not attached to the final element of the plain tone, and the symbol (D) indicating the tone is added to the final element of the down tone.

There are four types of modern Tibetan tones (high, low, high and low) shown in Table 8 below.

[0048]

[Table 8]

Although ancient Tibetan originally did not have a tone, modern Tibetan mainly produces an assimilation of the ancient Tibetan vowel, producing a high or low tone, and the final (especially the final, ie, Assimilation of the vowel a, i, u, e or o) resulted in a flat or down tone. In the input of the tone in the first embodiment, the distinction of the tone of high or low is designated at the time of inputting the initial, and the distinction of the tone of flat or down is designated at the time of inputting the final. Thus, the method of specifying the tone of the Tibetan language in two parts is suitable from the viewpoint of the origin of the tone, the composition of the Tibetan characters, and the pronunciation of the real world.

Next, the configuration and operation of the first embodiment of the present invention in the case where the above-described method for specifying the tone of the Tibetan language is applied will be described in detail. In the Tibetan input device 1 in the first embodiment of FIG. 3, the input means 3 of FIG.
Is provided with a keyboard 10 on which a plurality of keys (key means) are arranged. The keyboard 10 generates a reading code (a first reading code and a second reading code, typically a voice and a final) and other key codes when a user taps a predetermined key. Keyboard 1

It is also realized by software such as a character conversion processing program provided by a PU (Microprocessor Unit) or the like.

Further, in FIG. 3, reference numeral 21 denotes an input mode flag. When the value of this flag is "0", it indicates a voice input mode (corresponding to the first reading code input mode). "1" indicates the final input mode (corresponding to the second reading code input mode). The voice input mode and the final input mode are automatically switched by the character conversion control unit 20 when a predetermined signal is transmitted by operating the keyboard 10.

In FIG. 3, reference numeral 22 denotes a conversion mode flag. When the value of this flag is "0", it indicates an unconverted mode indicating that the conversion operation from the read code to the character code has not been completed. When the value of the flag is "1", it indicates a converted mode indicating that the conversion operation from the reading code to the character code has been completed. In this case, the reading code input from the keyboard 10 is temporarily stored in the reading buffer 30 by the character conversion control unit 20.

Further, in FIG.
Is searched based on the reading code input to the character conversion control unit 20. Tibetan input device 1 of FIG.

Is provided. The character display section 90 displays the character codes stored in the character buffer 80 and displays the character codes stored in the homophone list buffer 70.

The character display section 90 is provided in the character buffer 8.
When displaying the character code stored in 0, the value of the input mode flag 21 in the character conversion control unit 20 is referred to, and a different color or luminance is used to input the character code in the voice input mode. It has a function of distinguishing and displaying Tibetan characters and Tibetan characters input in the final input mode.

Further, the character conversion control unit 20 shown in FIG. 3 can control the Tibetan character representing each syllable even if the user does not operate a specific conversion key on the keyboard 10 after an arbitrary reading code is input. It also has a function of outputting the most frequently used character code (ordinary term) and storing it in the character buffer 80. Further, in FIG. 3, reference numeral 45 denotes a display character defining means comprising a rewritable storage device or the like. By using this display character defining means, the user himself / herself can recognize the vowels and syllables stored in the character table 40. Can be arbitrarily defined.

More specifically, the keyboard 10 shown in FIG. 3 has a first reading code and a second reading code (typically, an initial and a final) constituting Tibetan reading.
Reading code input unit 3-1 for inputting each of
Also, a plurality of keys (not shown in FIG. 3) having the function of the second reading code input unit 3-2 are arranged.
Preferably, for each of these keys, a first reading code and a second reading code, as shown in FIGS.
Both reading codes are assigned in a shared manner.
In the key configuration on the keyboard 10 as described above, all syllables in the Tibetan language are input by independent key tapping operations in units of the first reading code and the second reading code.

FIG. 4 is a diagram showing the left-hand part of the key arrangement example of the keyboard in the embodiment of FIG. 3, and FIG.
FIG. 11 is a diagram showing a right-hand part of a key arrangement example of a keyboard in the embodiment of FIG. Here, a plurality of keys on the keyboard 10 used for inputting the Tibetan language are roughly divided into four parts: a left hand input key 11, a right hand input key 12, a left shift key 13, and a right shift key 14. ing. Note that the left hand input key 11 and the right hand input key 1
11A, 11B, 12C and 1 shown at 2 predetermined positions
1D shows a key (usually referred to as a reading key) for inputting a Tibetan reading that indicates the meaning of “noble” illustrated in FIGS. 12 and 13 described later.

Hereinafter, the reason why the above-described key arrangement is adopted will be described. Fig. 4
The key top portion of the reading key in FIGS. 6 to 9 (to be described in detail later) shown after FIG. 5 is described using a Roman character in which a Tibetan initial or final is transcribed. The correspondence between Tibetan characters and Roman characters is as shown in Tables 3 to 7 above.

FIGS. 6 and 7 are diagrams showing the left hand portion and the right hand portion, respectively, of the example of the assignment of the input keys of the keyboard in the embodiment of FIG. FIGS. 8 and 9 are diagrams respectively showing the left-hand part and the right-hand part of the example of the assignment of the keyboard input keys of the keyboard in the embodiment of FIG. FIGS. 4 to 9 are diagrams for explaining the principle of the key arrangement, and do not show that the arrangement of the individual initials and finals is actually set at the above positions. .

First, an example of the assignment of an initial input key for inputting an initial will be described with reference to FIGS.
The harmonic clear consonants and low tone consonants classified in Tables 3 and 4 described above are input by pressing the reading key to which the voice is assigned alone. On the other hand, if the reading key to which the vowel is assigned is in the left hand part, the low tone clear consonant and the harmonic consonant mono consonant categorized in Tables 3 and 4 described above are input to the left hand input key 11 and the left shift key 13. On the other hand, if the reading key is in the right hand portion, the input is performed by simultaneously pressing the right hand input key 12 and the right shift key 14.

Further, if the reading key to which the vowel is assigned is in the left hand portion, the low-tone double consonants categorized in Table 5 above are input by simultaneously pressing the left hand input key 11 and the right shift key 14. If the reading key is in the right hand part, the right hand input key 12 and the left shift key 13
Is input by performing simultaneous keying. Then
With reference to FIGS. 8 and 9, an example of assignment of a final input key for inputting a final will be described.

In each of FIGS. 8 and 9, the final part written at the lower position of each key top part is input by performing a single key press on the reading key, and the upper part and the left side of each key top part are input. Are input by simultaneously keying the reading key and the left shift key 13, and the final note written above and to the right of each key top portion are the reading key and the right shift key. 14 by inputting the same key at the same time.

FIGS. 6 and 7 are diagrams for explaining examples of the assignment of initial input keys, and FIGS. 8 and 9 are diagrams for explaining examples of the assignment of final input keys. The keys are shown by superimposing the keys of FIGS. 6 and 7 and the keys of FIGS. 8 and 9 in units of a left hand part and a right hand part. However, in the key top portions of FIGS. 4 and 5, attempts have been made to simplify the engraving within a range that can be easily associated by the user.

For example, with regard to the initial, only the characters for the case of inputting with a single key are described. However, for the initials which are input simultaneously with the shift key (left shift key or right shift key), mainly the respective reading keys are used. Only changes from high to low or from low to high. Therefore, since it can be easily associated with the written voice, it is possible to omit the engraving of the character representing the voice to be input by simultaneous keying. Further, the symbols indicating the distinction between the main vowels a, i, u, e, and o of the final vowel are engraved only on the middle reading key, and the characters indicating the final ending (the one following the main vowel) are 1 Only places are provided.

Although FIGS. 4 and 5 show only arrangement examples of reading keys for inputting Tibetan readings,
Other various input keys such as a conversion key and a word selection key are assigned to keys shown in FIGS. 4 and 5 or keys not shown. As an example, the single tap of the right shift key 14 is defined as a single syllable conversion key having the function of a one-syllable word conversion key unit, and the single tap of the left shift key 13 is defined as a double syllable having the function of a double syllable word conversion key unit. It can be defined as a conversion key. Further, any function key other than the reading key and the shift key on the keyboard 10 can be defined as a word selection key having a function of word selection key means.

In the first embodiment, both the initial and final are assigned to the same reading key. FIG.
When the character conversion processing program constituting the character conversion control unit 20 converts the Tibetan reading code into the character code, it is necessary to recognize whether the key that has been hit is the initial or final. Therefore, by providing the input mode flag 21 in the character conversion processing program, it is possible to identify the reading code input by the current key operation of the reading key.

Here, if the value of the input mode flag 21 is "0" (voice input mode), the character conversion processing program stores the character code representing the voice in the read key that has been hit in the character buffer 80. I do. On the other hand, if the value of the input mode flag 21 is "1" (final input mode), the character conversion processing program adds a vowel input immediately before the final input to the final in the read-in key. Is stored in the character buffer 80.

When the character conversion processing program converts a reading code into a character code, a syllable terminating symbol 'is added after each syllable. In the conventional Tibetan input method, the number of times of keying for inputting a syllable end symbol is the largest. However, in the first embodiment, the syllable end symbol is automatically added using a character conversion processing program. Therefore, the number of keystrokes for inputting the syllable end symbol can be set to zero (0).

FIGS. 10 and 11 are flow charts (Nos. 1 and 2) for explaining the operation of the character conversion control unit in the embodiment of FIG. Based on FIGS. 10 and 11, a description will be given of a processing procedure (hereinafter, 〜) of a character conversion processing program constituting the character conversion control unit 20 of the embodiment (first embodiment) of FIG. When converting the Tibetan reading into a character code using the Tibetan input device of the first embodiment (FIG. 3), first,
In step S101 in FIG. 10, the value of the input mode flag 21 is set to "0" to set the initial input mode.

Next, the character conversion processing program waits for a key input from the keyboard 10 (step S 10
2) When a key code is sent from the keyboard 10, the type of the key code is determined. If it is confirmed that the sent key code is a reading key (step S103), the processing described later is executed.
If the sent key code is a key other than the reading key and is a conversion key (single syllable conversion key or double syllable conversion key)
And if it is confirmed that the key is a word selection key (FIG. 11
Steps S104, S105 and S106), the processing described later and the above-described processing are executed. If it is confirmed that the transmitted key code is a confirmation key indicating that the conversion operation from the reading code to the character code has been completed (step S107 in FIG. 11), the confirmation processing described later is performed. The above processing is executed. If the transmitted key code is confirmed to be a key other than the above keys (step S107), processing based on the key (step S108 in FIG. 11) and the above processing are executed. .

The character conversion processing program is executed by the keyboard 1
Each time a key code is sent from 0, the above processing is repeated. Further, when it is confirmed that the sent key code is a reading key (step S103), step S1 is performed.
At 09, the character conversion processing program checks the conversion mode flag 22. If conversion mode flag 2
If the value of 2 is "1" and it is confirmed that the mode is the converted mode, first, a confirmation process described later is performed (step S110), and then the input mode flag 21 is checked (step S111). ).

If the value of the input mode flag 21 is "0"
If it is confirmed that the input mode is the (vowel input mode), the transmitted reading code is stored in the reading buffer 30 (step S112), and the character table 40 is searched based on the reading code (step S112). Step S113). Further, a character code representing a voice detected as a result of searching character table 40 is stored in character buffer 80 (step S114).
Is changed to "1" (final input mode) (step S
115).

If the value of the input mode flag 21 is "1"
If it is confirmed that the input mode is the (final input mode), the transmitted reading code is stored in the reading buffer 30 (step S116), and the reading code of the voice input immediately before the reading code is stored. Plus character table 4
0 is searched (step S117). Further, a character code representing a syllable detected as a result of searching the character table 40 is stored in the character buffer 80 (step S1).
18) Then, the value of the input mode flag 21 is set to “0”
(Voice input mode) (step S119).

Further, the character conversion processing program
It is checked whether the transmitted key code is a one-syllable conversion key (step S104 in FIG. 11). If it is confirmed that the sent key code is a one-syllable conversion key, a one-syllable read code is extracted from the last part of the read code in the read buffer 30, and the one-syllable read is read. The one-syllable word dictionary 50 is searched based on the code (step S120). If there is a homonym corresponding to the reading code in the one-syllable word dictionary 50, a list of character codes constituting the homonym is stored in the homonym list buffer 70 (step S121). The character code of the word located at the head of the homophone is stored in the character buffer 80 (step S122).

Further, the character conversion processing program checks whether or not the sent key code is a double syllable conversion key (step S105). If the sent key code is confirmed to be a double syllable conversion key, the last part of the read code in the read buffer
The syllable reading code is extracted, and the double syllable word dictionary 60 is searched based on the reading code of two syllables (step S124). If there is a homonym corresponding to the reading code in the double syllable word dictionary 60, a list of character codes constituting the homonym is stored in the homonym list buffer 70 (step S121). The character code of the word located at the head of the homophone is stored in the character buffer 80 (step S122).

If there is no homophone corresponding to the reading code in the double-syllabic word dictionary 60, a reading code added by one syllable is taken out from the last part of the reading code in the reading buffer 30, and this is also read. And double syllable word dictionary 60
Search again. Furthermore, the character conversion processing program
It is checked whether or not the sent key code is a word selection key (step S106). If it is confirmed that the sent key code is the word selection key, a number is calculated from the sent key code and the same word list buffer 70 is searched (step S125), and the number corresponding to the number is calculated. The character code of the word is extracted and stored in the character buffer 80.

When the above processing is completed, the value of the conversion mode flag 22 is changed to "1" (converted mode) (step S123). Further, the character conversion processing program outputs the character code stored in the character buffer 80 when confirming that the sent key code is the determined key (step S126), and outputs the character buffer 80 and the reading buffer. 30 (Steps S127 and S12)
8) The value of the conversion mode flag 22 is set to "0" (unconverted mode) (step S129). That is, a confirmation process is executed.

In the configuration of the first embodiment of the Tibetan input device as described above, if the user inputs a Tibetan reading in the order of the initial and the final, the reading code is converted into Tibetan characters by the character conversion processing program. The result of the conversion is displayed on a display or the like of the character display unit 90. Here, when the user wants to change the above conversion result to another word, the user can achieve the purpose by pressing a single syllable conversion key, a double syllable conversion key, or the like.

FIGS. 12 and 13 are flowcharts (parts 1 and 2) for explaining the specific operation of each part when a Tibetan character is input in the embodiment of FIG.

Further, the value of the conversion mode flag 22 is set to "1" (converted mode), and the value of the input mode flag 21 is set to "0" (voice input mode) (step S242). Finally, the character display unit 90 displays the character code in the character buffer 80 (Step S243).

In the first embodiment of the present invention, the above-mentioned a) to
According to the processing procedure of (e), the reading of an arbitrary Tibetan word (for example, “noble”) can be input and converted into the corresponding Tibetan character quickly with a much smaller number of key strokes than before, and clearly displayed on a display or the like. Can be displayed. FIG. 14 is a block diagram showing a configuration of an embodiment based on the second principle configuration of the present invention. Here, the configuration of the Tibetan input device 1 for realizing the second principle configuration shown in FIG. 2 will be described in detail.

In describing an embodiment (hereinafter abbreviated as a second embodiment) based on the second principle configuration of the present invention,
First, a Tibetan character string representing a Tibetan phoneme is classified in a unique format. As shown in each of FIGS. 26 and 27 described above, the Tibetan character is a character string representing a consonant part composed of letters A, B, C and D, and a vowel composed of letters / symbols E, F and G. It is composed of a character string representing a part.

In the consonant parts, A and B are characters (ie, character strings) representing a pre-consonant, C is a basic consonant, and
D is a letter representing a post-consonant. In this case, in order to distinguish between A and B, A is called a front character and B is called a superscript. On the other hand, in the vowel part, E is a symbol representing a main vowel, and F and G are characters (that is, character strings) representing a ending.

The character part constituting the Tibetan character string is
It can be roughly divided into characters that represent a pre-consonant such as A and B (pre-consonant characters), characters that represent basic consonants and post-consonants such as C and D (basic consonant characters and post-consonant characters), ,
There are three units: a symbol representing a main vowel (primary vowel symbol) such as E, F, and G and a character representing a ending (final ending character).

As the characters representing the pre-consonants, those shown in Table 9 below are given.

[0096]

[Table 9]

Further, as the characters representing the basic consonant and the post-consonant, those shown in Tables 10 and 11 below are given.

[Table 12]

[0102]

[Table 13]

Here, in consideration of the reading of the Tibetan language, each syllable is decomposed into, for example, a character string composed of the above three types of character parts, and a Tibetan word is input in units of these character parts. The configuration and operation of the second embodiment of the present invention in the case where such a designation method based on the character unit is applied will be described in detail. In the Tibetan input device 1 according to the second embodiment shown in FIG. 14, a keyboard 10 having a plurality of keys (key means) is provided as the input means 3 as in the first embodiment shown in FIG. Provided. When the user taps a predetermined key, the keyboard 10 changes a key code indicating a pre-consonant character, a basic consonant character and a post-consonant character, a main vowel symbol and a suffix character, and other key codes. Generated. An example of the key arrangement of the keyboard 10 is shown in FIGS. 15 and 16 described later.

Further, in FIG. 14, the character string / character code conversion means 6 and the spelling conversion means 7 are constituted by a character conversion control unit 20. This character conversion control unit 20
Searches the character table 40 and the spelling conversion dictionary (also referred to as an allomorph conversion dictionary) 55 based on the key code sent from the keyboard 10, converts the key code into a character code, and stores it in the character buffer 80. Things.

The character conversion control unit 20 described above uses FIG.
CPU or MPU as in the first embodiment of
It is also realized by software such as a character conversion processing program provided by the above. In FIG. 14, reference numeral 21 'denotes an input mode flag. When the value of this flag is "0", it indicates a consonant part input mode (a mode for inputting a pre-consonant, a basic consonant, and a post-consonant). When the value of the flag is “1”, it indicates a vowel part input mode (a mode in which a main vowel and a vowel are input).

In FIG. 14, reference numeral 23 denotes a pre-consonant check flag. When the value of this flag is "0", it indicates that a character representing the pre-consonant has not been input. Is "1", indicating that the character representing the pre-consonant has been input. Further, in FIG. 14, the character table 40 is searched based on the key code input to the character conversion control unit 20, as in the case of the first embodiment of FIG. The Tibetan input device 1 of FIG. 14 is configured so that the character code of the corresponding Tibetan character can be detected by searching the character table 40 as described above.

Further, in FIG. 14, the spelling conversion dictionary 5
Reference numeral 5 denotes a search performed based on the key code input to the character conversion control unit 20 when a conversion key having the function of the spelling conversion instruction unit 3-4 (FIG. 2) is pressed.
The Tibetan input device 1 of FIG. 14 is configured to be able to detect an allomorph corresponding to a regular Tibetan word by searching the spelling conversion dictionary 55 as described above.

Further, in FIG. 14, the character buffer 8
0 has a function of storing a character code detected from the character table 40 and the spelling conversion dictionary 55 by the character conversion control unit 20, as in the case of the first embodiment of FIG. Further, in FIG. 3, a character display section 90 composed of a CRT, an LCD, or the like is provided as the character display means 9 of FIG. 2, as in the case of the first embodiment of FIG. The character display section 90 displays a character code stored in the character buffer 80.

More specifically, the keyboard 10 shown in FIG. 3 includes a character string representing each syllable in Tibetan (typically, a pre-consonant character, a basic consonant character and a post-consonant character, and a main vowel symbol and A plurality of keys having a function of a character string input unit 3-3 for inputting a character string composed of ending characters) are arranged. Furthermore, the keyboard 10 of FIG.
In addition to the above-described character string input keys, a spelling conversion instructing unit 3-
A conversion key having four functions is arranged.

FIG. 15 is a diagram showing the left-hand portion of the key arrangement example of the keyboard in the embodiment of FIG.
FIG. 15 is a diagram showing a right-hand part of an example of a key arrangement of a keyboard in the embodiment of FIG. 14; Here, a plurality of keys on the keyboard 10 used for inputting the Tibetan language are roughly divided into four parts: a left hand input key 11, a right hand input key 12, a left shift key 13, and a right shift key 14. ing. Note that 11E, 12F, 12 shown at predetermined positions of the left hand input key 11 and the right hand input key 12 are shown.
G and 12H indicate keys (usually called character keys) for inputting a Tibetan character string representing the meaning of “lost” exemplified in FIGS. 23 and 24 described later.

The reason why the above-described key arrangement is adopted will be described below. For simplicity, Figure 1
5 and 16 (shown in detail later), the key tops of the letter keys are the pre-consonant characters, the basic consonant characters and the post-consonant characters, and the main vowel symbols in Tibetan. It is described using Roman characters that transcribe the ending characters. The correspondence between Tibetan characters and Roman characters is as shown in Tables 9 to 13 above.

FIGS. 17 and 18 correspond to FIG.
FIG. 21 is a diagram showing a left-hand part and a right-hand part of an example of assignment of consonant character (prefixed consonant character, basic consonant character, and postfixed consonant character) input keys of the keyboard in the embodiment of FIG. FIGS. 19 and 20 are diagrams showing the left-hand portion and the right-hand portion, respectively, of the example of assigning the vowel character (main vowel symbol and ending character) input keys of the keyboard in the embodiment of FIG.

FIGS. 15 to 20 are diagrams for explaining the principle of the key arrangement, and do not show that the individual character arrangements are actually set at the positions as described above. . Next, examples of key assignment for inputting a pre-consonant character, a basic consonant character and a post-consonant character, and a main vowel symbol and a final vowel will be described with reference to FIGS.

In FIGS. 17 and 18, the keys with hatching added are keys for inputting pre-consonant characters, and the keys without hatching are input for basic consonant characters and post-consonant characters. Is the key. 17 to 2
In the case of 0, the character written at the lower position of each key top portion is input by tapping the character key alone.

On the other hand, the characters written above and to the left of each key-top portion are input by simultaneously pressing the character key and the left shift key 13 to enter the characters above and to the right of each key-top portion. Is entered by simultaneously keying the character key and the right shift key 14. The keys for character string input shown in FIGS. 14 and 15 are obtained by superimposing the consonant character input keys of the keyboard of FIGS. 17 and 18 and the vowel character input keys of FIGS. 19 and 20. . However, in the key top portion of FIGS. 14 and 15, an attempt is made to simplify the engraving within a range that can be easily associated by the user.

For example, for the characters and symbols of the vowel part,
Only characters for single-key input are shown. However, the characters / symbols of the vowel parts which are input by simultaneously tapping with the shift key (left shift key or right shift key) can be easily associated mainly with the vowel parts written on the respective character keys. It is possible to omit the engraving of characters / symbols representing vowel parts to be input by simultaneous keystroke.

Although FIGS. 15 and 16 show only an example of arrangement of character keys for inputting Tibetan characters, other various input keys such as a conversion key for spelling conversion are required. 15 and 16 are assigned to the keys shown or not shown. As an example,
A single keystroke of the right shift key 14 can be defined as a conversion key for spelling conversion.

In the second embodiment, both a consonant part and a vowel part are assigned to the same character key.
When the character conversion processing program constituting the character conversion control unit 20 shown in FIG. 14 converts a key code representing a Tibetan character string into a character code, whether the keystroke is a character representing a consonant part or a vowel It is necessary to recognize whether the character is a part. Therefore, the input mode flag 21 'and the pre-consonant check flag 23 are added to the character conversion processing program.
Is provided so that the key code input by the current character key input can be identified.

Here, if the value of the input mode flag 21 'is "0" (consonant part input mode), the character conversion processing program stores the character code representing the consonant part in the keyed character key in the character buffer 80. Store in. Meanwhile,
If the value of the input mode flag 21 'is "1" (vowel part input mode), the character conversion processing program adds the syllable terminating symbol' to the character code representing the vowel part in the keyed character key. It is stored in the character buffer 80.

When the value of the pre-consonant check flag 23 is "0" (not input), the character conversion processing program validates the key input of the pre-consonant character input key. Is "1" (input completed), the key input of the pre-consonant character input key is invalidated. FIGS. 21 and 22 are flowcharts (Nos. 1 and 2) for explaining the operation of the character conversion control unit in the embodiment of FIG. Based on these FIG. 21 and FIG. 22, the processing procedure of the character conversion processing program constituting the character conversion control unit 20 of the embodiment (second embodiment) of FIG.
To (5)).

(1) When converting a Tibetan character string into a character code using the Tibetan input device of the second embodiment (FIG. 14), first, in step S301 of FIG.
The value of the input mode flag 21 'is set to "0" to set the consonant part input mode. In this case, the character representing the pre-consonant is
Naturally, no input has been made (step S3).
02).

(2) Next, the character conversion processing program waits for a key input from the keyboard 10 (step S30).
3) When a key code is sent from the keyboard 10, the type of the key code is determined. If the sent key code is confirmed to be a character key (step S304), the input mode flag 21 'is checked (step S305), and the value of the input mode flag 21' is set to "0" (consonant part input). Mode), (3) described later
Is performed. If the input mode flag 2
If the value of 1 'is "1" (vowel part input mode), the processing of (4) described later is executed. On the other hand, when it is confirmed that the transmitted key code is not a character key but a conversion key (step S322 in FIG. 22), the following (5) will be described.
And the above (1) are executed. If the transmitted key code is confirmed to be a key other than the above keys, the processing based on the key (step S325 in FIG. 22) and the processing of (1) are executed.

The character conversion processing program is executed on the keyboard 1
Each time a key code is sent from 0, the above process (2) is repeated. (3) Further, when it is confirmed that the value of the input mode flag 21 'is "0" and the consonant part input mode is set (step S305), the character conversion processing program executes the pre-consonant character key (FIG. 15). And whether the corresponding key code has been input by tapping the key (key indicated by hatching in FIG. 16) (step S306), and checking the pre-consonant check flag 23 (step S307 and Step S313 in FIG. 22).

If the input is a pre-consonant character key,
If it is confirmed that the value of the pre-consonant check flag 23 is "0" (not input), first, the character buffer 80 is cleared (step S308), and the next transmitted key code is entered. The character table 40 is searched based on the search (step S309). Further, the character code detected as a result of searching the character table 40 is stored in the character buffer 80 (step S310), and then the value of the pre-consonant check flag 23 is set to "1" (input completed) (step S310). S311).

If the input is a pre-consonant character key,
If it is confirmed that the value of the pre-consonant check flag 23 is "1" (input completed), it is considered that the pre-consonant character input key has been hit twice, and the pre-consonant character input is performed. The input of the key code sent from the key is invalidated (step S312). If the input is not a pre-consonant character key input and it is confirmed that the value of the pre-consonant check flag 23 is "0" (not input), the character buffer 80 is cleared (step in FIG. 22). After S314), the character table 40 is searched based on the sent key code (step S315 in FIG. 22). Further, a character code detected as a result of searching the character table 40 is stored in the character buffer 80 (step S in FIG. 22).
316) Then, the value of the input mode flag 21 'is set to "1" (vowel input mode) (step S317 in FIG. 22). If the value of the pre-consonant check flag 23 is not "0" (uninput), the character table 40 is searched without clearing the character buffer 80.

(4) On the other hand, the input mode flag 21 '
Is "1" and the vowel part input mode is confirmed (step S305), the character conversion processing program executes the character conversion processing program based on the sent key code. (Step S318 in FIG. 22). Further, a character code detected as a result of searching the character table 40 is stored in the character buffer 80.
(Step S319), then set the value of the input mode flag 21 'to "0" (consonant part input mode) (step S320), and set the value of the pre-consonant check flag 23 to "0" (not yet (Input) (step S32)
1).

(5) Further, the character conversion processing program
Upon confirming that the sent key code is a conversion key, the spelling conversion dictionary 55 is searched based on the character code input immediately before (step S323). Further, the character code detected as a result of searching the spelling conversion dictionary 55 is stored in the character buffer 80 (step S32).
4).

In the configuration of the second embodiment of the Tibetan input device as described above, if the user inputs the consonant character and the vowel character of Tibetan one by one in the unit of the three character parts described above, The corresponding character code is easily detected in units of character parts by the character conversion processing program, and the Tibetan character based on this character code is displayed in the character display unit 90.
Is displayed on a display or the like. In this case, the number of keystrokes required to input a Tibetan character string representing all syllables in modern Tibetan can be suppressed to three or less,
It becomes possible to input each syllable of Tibetan much more efficiently than the conventional Tibetan input method.

Further, when it is desired to convert the spelling of the modern Tibetan to the spelling of the ancient Tibetan, by pressing the conversion key, the allomorph corresponding to the ortholog of the modern Tibetan input immediately before can be quickly changed. Is detected and displayed. FIGS. 23 and 24 are flowcharts (parts 1 and 2) for explaining the specific operation of each unit when a Tibetan character is input in the embodiment of FIG.

Here, with reference to FIG. 23 and FIG. 24, the operation of each part when a Tibetan character representing the meaning of “lost” (PrK for Roman transcription, r for basic consonant) is specifically input, and Next, the operation of each unit when a regular Tibetan character (an example in which the Roman character transcription is n) is converted to an allograph will be described ((a) to (e) below). In FIGS. 23 and 24, the blocks in the left column show the keys that have been hit, and the blocks in the middle column show the processing by the character conversion processing program based on the keys in the blocks in the left column. . The blocks in the right column indicate the contents of the character buffer 80 displayed by the character display unit 90. Note that, for convenience of explanation, the blocks in FIGS. 23 and 24 are given the numbers of steps S401 to S443.

(A) First, in step S401 in FIG. 23, a character key (pre-consonant character key) 1 representing a pre-consonant
When 1E (see FIG. 15) is pressed, the value of the input mode flag 21 'is "0" (consonant part input mode) in the initial state.
And the value of the pre-consonant check flag 23 is also “0” (not input), so the character conversion processing program clears the character buffer 80 and deletes the pre-consonant character key. At this time, a Tibetan character representing the pre-consonant P in the character table 40 is searched and written in the character buffer 80. Thereafter, the value of the pre-consonant check flag 23 is set to “1”.
(Input completed) (step S402). Character display section 9
0 indicates the Tibetan character written in the character buffer 80 (step S403).

(B) Next, in step S411, when the character key 12F and the right shift key 14 are simultaneously pressed,
Since the value of the input mode flag 21 'is "0" (consonant part input mode), the character conversion processing program searches for a Tibetan character representing the basic consonant r and the rear consonant l based on the character key. And writes it in the character buffer 80. Thereafter, the value of the input mode flag 21 'is set to "1" (vowel input mode) (step S412). Character display section 90
Displays the Tibetan character written in the character buffer 80 (step S413).

(C) Further, in step S421 in FIG. 24, when the character key 12G is depressed, the value of the input mode flag 21 'is "1" (vowel input mode). The program searches the character table 40 for a Tibetan character representing the ending character Ks (without a main vowel symbol) in the character table 40 based on the character code, and searches the character buffer 8.
Write to 0. Then, the value of the input mode flag 21 'is set to "0" (consonant part input mode), and the value of the pre-consonant check flag 23 is set to "0" (not input) (step S422). The character display section 90 includes a character buffer 80.
Is displayed (step S4).
23).

(D) Further, in step S431,
When the character key 12H is pressed, the input mode flag 2
The value of 1 'is "0" (consonant part input mode),
In addition, since the value of the pre-consonant check flag 23 is also "0" (not input), the character conversion processing program clears the character buffer 80 and stores the basic character in the character table 40 in the character table 40 based on the character key. The Tibetan character representing the consonant n is searched and written in the character buffer 80. Thereafter, the value of the input mode flag 21 'is set to "1" (vowel input mode) (step S432). The character display unit 90 displays the Tibetan characters written in the character buffer 80 (Step S433).

(E) Further, in step S441,
When the right shift key 14 is pressed alone, the character conversion processing program considers that the conversion key has been pressed, and searches the spelling conversion dictionary 55 for an allomorph corresponding to a regular Tibetan character of the present day representing the basic consonant n. Further, an allomorph detected as a result of searching the spelling conversion dictionary 55 is written in the character buffer 80. The character display unit 90 displays the Tibetan character written in the character buffer 80 (Step S443).

In the second embodiment of the present invention, the above (a) to
According to the processing procedure of (e), a character string of an arbitrary Tibetan language (for example, “lost”) can be input and the corresponding Tibetan character can be quickly displayed with a much smaller number of key strokes than in the past. Can be quickly detected and displayed.
FIG. 25 is a diagram for explaining the specifications of a keyboard when performing an input of Tibetan language according to the present invention using an alphabetic keyboard. 3 to 24, the configuration and operation of the embodiment of the present invention have been described only for the case where reading or inputting of Tibetan is executed on a thumb shift keyboard having two left and right shift keys. However, as shown in FIG. 25, it is also possible to use the English keyboard to read Tibetan or input characters according to the present invention.

For example, FIG. 4 and FIG.
When the Tibetan readings or characters are arranged on the keyboard of FIG. 16, the frequency of use of these Tibetan readings or characters is roughly divided into three ranks, and the input method at each rank is determined as follows. I have. Rank A: Frequently used ・ Enter the reading key or character key by tapping it alone B Rank: Moderately used ・ Enter the reading key or character key of the left hand by pressing the left shift key at the same time・ Enter the right hand reading key or character key simultaneously with the right shift key and enter it. C rank: Infrequently used ・ Left hand reading key or character key simultaneously input with the right shift key and enter ・ Right hand part Input the reading key or character key by typing it at the same time as the left shift key. The key layout is determined for each rank of the reading frequency of the Tibetan language or the use frequency of the character according to the above specifications. In the case of performing input on the thumb shift keyboard, as shown in FIG. 25, an English-language keyboard 10 'widely used in the general public.
When inputting Tibetan readings or characters using, it is desirable to adopt the following specifications.

Rank A: frequently used. Alphabet key 11 'corresponding to a reading key or a character key (abbreviated as a reading / character key in FIG. 25) is input by inputting a single key alone. B rank: used Medium frequency ・ Enter the alphabet key 11 ′ corresponding to the reading key or character key simultaneously with the blank key 14 ′ and input. C rank: Infrequently used ・ English key corresponding to the reading key or character key. 11 'is the shift key (left shift key 12' or right shift key 1
3 ') and the alphabet key 11' corresponding to the reading key or character key while pressing the shift key.
In this case, use the right shift key 13 'when inputting the alphabet key 11' corresponding to the reading key or character key of the left hand, and the alphabet corresponding to the reading key or character key of the right hand. It is convenient to use the left shift key 12 'when inputting the key 11' As described above, when using the thumb shift keyboard or the alphabet keyboard to input Tibetan readings or characters according to the present invention. Is also possible.

As described above, according to the Tibetan input device of the present invention, first, the keys corresponding to the first reading code and the second reading code constituting the reading of Tibetan, respectively, are assigned to a keyboard or the like. , All syllables of the Tibetan language are input by independent key operations in units of the first reading code and the second reading code. Therefore, when inputting each syllable of the Tibetan language by tapping the above key, the number of times of keying can be suppressed to two times, so that each syllable of the Tibetan language is much more efficiently than the conventional Tibetan input method. Can be entered.

Further, according to the Tibetan input device of the present invention, second, the keys corresponding to the first reading code and the second reading code are shared on the keyboard, and the first reading code input mode and the second reading code input mode are used. The reading code input mode is automatically switched. Therefore, the number of keys used for key input can be suppressed to about the same level as in the case of conventional Tibetan input even though the number of key inputs is reduced.

Thirdly, according to the Tibetan input device of the present invention, the user inputs a syllable end symbol which must be input at the end of each syllable in the conventional Tibetan input device. Since the function of automatically adding the syllables is realized even if the syllables are not included, the input efficiency of each syllable in Tibetan can be further improved. Furthermore, according to the Tibetan input device of the present invention, fourthly, when converting the Tibetan reading into Tibetan characters and displaying the Tibetan characters on the character display means or the like,
Since different colors or luminances are used for the reading code and the second reading code, it is possible to clearly identify the display of the first reading code and each syllable.

Fifth, according to the Tibetan input device of the present invention, immediately after the user inputs the first reading code or the second reading code, the user does not need to press a conversion key or the like on the keyboard. Since the most frequently used Tibetan character among the Tibetan characters representing the syllable is automatically converted, the most common term of each syllable is obtained faster and more reliably.

Furthermore, according to the Tibetan input device of the present invention, sixthly, the first reading code and the Tibetan character representing a syllable that are automatically converted immediately after the first reading code and the second reading code are input are described below. Since the user can arbitrarily specify, the most common term that each user wants to use can be obtained faster and more reliably. Furthermore, according to the Tibetan input device of the present invention, seventhly, when one syllable word or a plurality of syllable words includes a plurality of homonyms, one syllable word or one of a plurality of syllable words is used. Since the keys are arranged so as to select a word, it is possible to obtain a single syllable word or a multiple syllable word other than the most common term faster.

Eighth, according to the Tibetan input device of the present invention, eighthly, the initials and the initials which are relatively easy to classify are converted into the first reading code and the second reading code constituting the reading of Tibetan. Since they correspond to each other, it is possible to easily input a reading corresponding to every syllable in Tibetan. Further, according to the Tibetan input device of the present invention, ninthly, each syllable of the Tibetan language is decomposed into a character string composed of three or less character parts, and a key for inputting the Tibetan word in units of these character parts Is arranged on an input means such as a keyboard. By tapping these keys, a Tibetan character string can be input in three units. Therefore, the number of times of tapping the above key to input a Tibetan character string representing all syllables of the modern Tibetan language can be suppressed to three or less, which is much more efficient than the conventional Tibetan input method. It becomes possible to input each syllable of the word.

Further, according to the Tibetan input device of the present invention, tenthly, a conversion key for performing conversion from the modern Tibetan spelling to the ancient Tibetan spelling is arranged, and the present Tibetan language is input. By operating the conversion key when an orthographic character is input, it is possible to easily input a Tibetan variant. Further, according to the Tibetan input device of the present invention, eleventh, a pre-consonant character, a basic consonant and a post-consonant character, which are relatively easy to classify, and
Since the main vowel symbol and the ending character are used as a unit of the character part constituting the Tibetan character string, it is possible to easily input a character string corresponding to every syllable in Tibetan.
