2. Description of the Related Art Recently, with the expansion of general wire communication service technology, Code Division Multiple Access (CDMA)
With the technical development of personal wireless communication services such as personal mobile communication based on ltiple access) technology, the number of subscribers is increasing dramatically. Therefore, various additional services have been developed and are being actively provided.

In particular, the character transfer service among such additional services has become of great interest to users because it can perform a character transfer function through a wireless communication terminal.

As an application field of the character transfer service, in addition to the short-sentence message service, it can be applied not only to the stock information service that provides market conditions by inputting a desired company name after connecting to the stock information telephone service through a telephone, There are various telephone voice information retrieval service systems such as library collection guides, airline ticket reservations, and unmanned telephone number guide services using the telephone. Also, an electronic notebook, Palm Top, which requires a small number of keyboards
Examples include small integrated keyboard systems such as computers, keyboard systems for operating and input devices such as Internet TV and digital still cameras, and input systems with similar structures and functions such as electronic locks and cash dispensers. be able to.

[0005]

The above-mentioned character transfer service requires a character input system capable of easily inputting characters, but it will be useful to provide the character transfer service with a limited number of keyboards. It should be possible to quickly extract and combine desired characters according to the intention of the user.

For this reason, various character input systems have been known which can meet such technical requirements, but this requires a large number of key button presses, and various key buttons must be pressed depending on the character. Therefore, there is a disadvantage that it is difficult to operate and takes time and effort when inputting.

[0007] Therefore, the present invention has been made in view of the above problems, and the purpose thereof is based on the new Japanese syllabary chart which is a modification of the standard Japanese syllabary chart, and the basic character corresponding to the stage of the new Japanese syllabary chart. When you want to input one character while arranging on each key of the reduced keyboard, use the basic character key with the basic character corresponding to that one character and the three function keys It is to provide a character input method using a reduced keyboard capable of inputting characters.

[0008]

In order to achieve the above object, the character input using the reduced keyboard of the present invention reconstructs the Japanese syllabary table for the implementation of the present invention.
It is called a 0-sound chart. In the present invention, characters are input based on the new Japanese syllabary chart. The new Japanese syllabary chart is a basic character corresponding to the Kiyon of Adan: A, Ka, Sa, Ta, Na, Ha, Ma, Ya, Ra, Is placed on the basic character key of the reduced keyboard, and the left shift key (KSL) and the right shift key (KSR) are placed to enter other characters that do not belong to that column, instead of the basic character. Jakuon, dakuon, semi-dakuon, which are not shown in the figure,
A transition key (KT) for inputting a desired character is arranged inside each stage of the new Japanese syllabary chart such as consonants, lowercase vowels, and sentence codes.

A new Japanese syllabary chart is presented in FIG.
While maintaining the new Japanese syllabary chart as the standard Japanese syllabary chart, the lines and rows are integrated to reduce the number of lines, and the text code (",",-,,,,? , 』,)) Are assigned.

A character input method using a reduced keyboard based on the new Japanese syllabary chart includes a first step of selecting and inputting a basic character corresponding to the clean sound of the column of the line to which the character to be input belongs; A second step in which a transfer function necessary for generating a character is called; and when the input character is the basic character of the selection, returns to the first step to input another character, and the input character is In case of the selected basic character, the third step in which the input character is generated by the called transfer function by using the KSL key, the KSR key and the KT key; and the third character is input to input another character. And a fourth step of returning to the first step.

"SR2" is defined by the function to search 3 steps, and when KSR is repeatedly pressed, Basis → SR1 → SR2 → Basis → SR1 → SR2 → ・ ・
・ You can search by the circulation method.

13) KT (Key Transformation, a key is separately installed on the terminal) KT is defined by a function button that performs a T (Transformation) function. The "Transformation" function is "Basis" in Figure 1,
"SL1", "SL2", "SR1", "SR2" T in each stage
It is defined by the function to search 1, T2, T3, and when KT is repeatedly pressed, it is possible to search by the cyclic method of T1 → T2 → T3 → T1 → T2 → T3 → ...

If a circulation method with SL (SR) function and T function is specified, pressing (KSL (KSR)) in (Basis, Tn) causes (SL1
(SR1), Tn) and then press KSL (KSR) to select (SL2 (SR
2), Tn). From this situation, K
Pressing SL (KSR) returns to (Basis, Tn), and pressing KSL (KSR) repeatedly causes (Basis, Tn) → (SL1 (SR1), Tn) → (SL2
(SR2), Tn) → (Basis, Tn) → (SL1 (SR1), Tn) → (SL2 (SR
2), Tn) → ... are searched in a cyclic manner.

When (KT) is pressed in (Basis, T1),
By transferring to (Basis, T2), pressing KT further transfers to (Basis, T3), and further pressing KT returns to (Basis, T1).
Pressing T repeatedly (Basis, T1) → (Basi

sis, T3) → ・ ・ ・ Search is performed by the method. This is SL1
The same can be applied to the (SR1) stage and the SL2 (SR2) stage. However, this applies to the characters corresponding to K4 and K6, and the characters corresponding to K1, K2, K3, and K8 are (Ba
sis, T1) → (Basis, T2) → (Basis, T1) → (Basis, T2) →
(Basis, T1) → (Basis, T2) → ... Search is performed by the method, and the same can be applied to the SL1 (SR1) stage and the SL2 (SR2) stage. Characters corresponding to K5, K7, and K9 do not have the cyclic structure applied by KT.

The reason for adopting such a cyclic input method is to promptly input a character that the user wants to input while the user presses the key several times while forgetting in the input process.
For example, if the input method is a linear input method, a character input procedure is specified by one, which may be very inconvenient for a character that requires several pressing operations.

With this definition, in the present invention, as in the example of FIG. 2, characters corresponding to the T1 column of the Basis column (that is, basic characters) are arranged in the 0th to 9th keys. The layout position of the keyboard presented in this figure is merely an example and can be changed depending on the situation, but the input method is the same. "Kan
The "a" key is used as a hiragana / katakana input selection key, and the "DEL" key is used to delete a character that is incorrectly input.

FIG. 4 shows the form of position information of each character in spatial coordinates in order to easily explain the principle of character input of the present invention.

[K1] to [K10] corresponding to basic characters are "ROW"
Configure the coordinate value of the axis, and the coordinate value of the "SHIFT" axis corresponds to the "Shift" line in Figure 1 (Basis, SL1, SL2, SR1, SR2)
Are placed. Moreover, T1, T2, and T3 of FIG. 1 are arranged at the coordinate values of the "TRANSFORMATION" axis.

The position of any character in space coordinates is
I promise to represent it with [ROW value: SHIFT value: TRANSFORMATION value]. For example, the position of "ka" in space coordinates is [K2: Basis: T1], the position of "ga" in space coordinates is [K2: Basis: T2], and the position of "ki" in space coordinates is [K2: Basis: T1]. K2: SL1: T1] The position of “Gi” in space coordinates is [K2: SL1: T2]
・ The position of each character can be displayed with etc.

Here, [ROW value: SHIFT value: TRANSFO
The basic coordinate value of [RMATION value] is [Kn: Basis: T1] (1 ≦ n
≦ 10), that is, the position coordinate value of the basic character,
No matter what character you enter, the basic coordinate value
ue) will be input.

According to the above definition of the key set, [K1] ...
The [K10] key is the first key to press to generate all characters, and when you press any of [K1] to [K10], the character corresponding to [Kn: Basis: T1], that is, the basic character is generated. [K1] ~ [K1
Every time you press [0], a basic character is generated.

Character input in the present invention is performed by three kinds of state transition methods.

First method This method is used for inputting characters corresponding to K4 (ta row) and K6 (was row) in FIG. 1. Referring to the chart of FIG.
Each "ta" line and "wa" line consists of 15 characters.
Each state is displayed using the coordinate expression method used for spatial coordinates, and a state transition diagram by key input is presented in Fig. 5. This transition diagram is presented. The function that defines the state transition is defined as the first transition function,
When the basic character key corresponding to "ta" or "wa" is pressed, the first transfer function is called, and the characters corresponding to K4 and K6 are input by the transfer of the state of FIG. 5 based on the first transfer function. . If the first transfer function is called, K4, K
If a character that does not correspond to 6 is entered (ie “ta”,
If another basic character that is not "ha" is input), this corresponds to the input of a basic character for inputting another character, and the transfer functions that perform the second and third methods described below are respectively Be called.

0 to 14 inside the circle are numbers representing each case of "15 states", and the coordinates showing the state are presented for each number.

Explaining an example of inputting an arbitrary character (for example, a consonant "tsu") using this transition diagram, there are six routes for inputting this character. That is, A. If you press the key corresponding to the basic character "ta: [K4: Basis: T1] state, No. 0" that corresponds to this character, the first transfer function is called, and if you press KSL once, you will see "C: [[ K4: SL1: T1] status, 9 ”
When you press KSL again, it will be transferred to “T: [K4: SL2: T1] state, No.10”. In this situation, if you press KT, it will be transferred to “Vacation Nod: [K4: SL2: T2] state, No. 11”, then K again.
When T is pressed, it is transferred to “Consonant: [K4: SL2: T3] state, No. 11”, and a character (pronounced) is generated.

B. The basic character "ta: [K4: B
asis: T1] State, No. 0 ”key is pressed to call the first transfer function, and KSL is pressed once,“ C: [K4: SL1: T1]
The state is moved to No. 9, and if you press KT in this situation, it will be transferred to the state of "Vacant sound ぢ: [K4: SL1: T2] state, No. 13 and then KT again.
When is pressed, it is transferred to “Dakuji no Ji: [K4: SL1: T3] state, No.14”. If you press KSL in this situation, “Konon :: K4: SL2: T
3] Characters (consonant) are generated by being transferred to state 12 ”.

C. The basic character "ta: [K4:
Basis: T1] state, press the key corresponding to 0 ”to call the first transfer function, and press KT to display“ D: [K4: Basis: T2]
It is transferred to the state No. 1, and when you press KT again, it is “:: K
4: Basis: T3] state, 2 ”transition. KSL in this situation
If you press, it will be changed to “Dakuji no Ji: [K4: SL1: T3] state, No.14”, and if you press KSL again, it will be changed to “Consonant sound: [K4: SL2: T3] state, No.12”. As a result, a character (consonant) is generated.

D. The basic character "ta: [K4:
When the key corresponding to Basis: T1] state, No. 0 ”is pressed, the first transfer function is called, and when KSL is pressed, it is transferred to“ C: [K4: SL1: T1] state, No. 9 ”. When you press KT, it will be transferred to “Dakuji no ぢ: [K4: SL1: T2] state, No. 13”, and further KSL
When is pressed, the state is changed to "Kakuon nozoku [K4: SL2: T2] state, No. 11". In this situation, if you press KT, you will see “Gakuon No: [K4: SL2: T3]
A character (prompted sound) is generated by being transferred to the state of No. 12 ”.

E. The basic character "ta: [K4: B
If you press the key corresponding to the "asis: T1] state, number 0", the first transfer function will be called, and if you press KT, it will be transferred to "D: [K4: Basis: T2] state, number 1". Press KSL to move to “Dakuji no ぢ: [K4: SL1: T2] state, No. 13”, and press KSL again to move to “Vacant sound [K4: SL2: T2] state, No. 11”. If you press KT in this situation, you will see "Kaneon no:: K4: SL
2: T3] state, the character (prompted sound) is generated by being transferred to the 12th ".

F. The basic character "ta: [K4:
When the key corresponding to the Basis: T1] state, 0th "is pressed, the first transfer function is called, and when KT is pressed, it is transferred to the" Da: [K4: Basis: T2] state, 1st ". When you press KSL at, it will be transferred to "Dakuji no ぢ: [K4: SL1: T2] state, No. 13".
If you press KT, it will be transferred to "Dakuji no Ji: [K4: SL1: T3] state, No. 14", and if you press KSL again, "Consonant sound: [K4: SL2: T3]".
A character (prompted sound) is generated by being transferred to the state of No. 12 ”.

When the KSL key is pressed in the state where the character (consonant) is generated, it is “Da: [K4: Basis: T due to the cyclic structure described above.
3] State is transferred to 2 ”, and if you press KT in this situation, it is transferred to“ ta: [K4: Basis: T1] state, 0 ”.
If you press KT when the character (gakuon no) is generated, it will be transferred to “T: [K4: SL2: T1] state, No. 10” due to the cyclic structure described above, and when you press the KSL key in this situation, : [K4: Basis: T1]
The state is transferred to 0 ".

Since the remaining characters are also made by the transition process shown in FIG. 5, a detailed description thereof will be omitted.

2) Second method In this method, K1 (A row), K2 (or row), K3 (Sa row), K8 (Ya-) in FIG.
It is used for inputting the characters corresponding to row (W) and K10 (other lines). Referring to the chart of FIG. 1, each set consists of 10 characters, which is defined as "10 states". Each state (sta
The display of (te) uses the coordinate expression method used for the spatial coordinates, and FIG. 6 presents a state transition diagram by key input. The function that defines the transition of the states presented in this transition diagram is defined as the second transition function, and "a", "ka", "sa",
The second transfer function is called when the basic character key corresponding to “Ya-wa” or “n” is pressed, and the characters corresponding to K1, K2, K3, K8, and K10 are based on the second transfer function of FIG. Input is made by state transition. If a character that does not correspond to K1, K2, K3, K8, or K10 is entered when the second transfer function is called (that is, a, ka, sa, ya-wa If it is input, it corresponds to the input of a basic character for inputting another character as described above, and the transfer functions for performing the first method and the third method described later are respectively called.

Here, 0 to 9 inside the circle are numbers representing each case of "10 states", and the coordinates showing the state are presented for each number.

Explaining an example of inputting an arbitrary character (for example, "zo") using this transition diagram, the route for inputting this character
There are 3 (routes). That is, A. If you press the key corresponding to the basic character “Sa: [K3: Basis: T1] state, No. 0” that corresponds to this character, the second transfer function is called, and once you press KSR, “Set: [ K3: SR1: T1] state, 2
No. ”, and when you press KSR again,“ So: [K3: SR2: T
1] State, 3rd ”. If you press KT in this situation, the character will be changed to“ Z: [K3: SR2: T2] state, 4th ”.
(Zo) is generated.

B. The basic character that corresponds to this character is "Sa: [K3: B
asis: T1] state, press the key corresponding to “0” to call the second transfer function, and press KSR once to “Set: [K3: SR1: T1]
It will be transferred to state 2, and if you press KT in this situation, you will get "ze:
It is transferred to [K3: SR1: T2] state, No. 5. If you press KSR again in this situation, it will be transferred to "No: [K3: SR2: T2] state, No. 4". Is generated.

C. The basic character that corresponds to this character is "Sa: [K3: B
When the key corresponding to the "asis: T1] state, number 0" is pressed, the second transition function is called, and when KT is pressed, the state is transitioned to "Z: [K3: Basis: T2] state, number 1". Press KSR at “”:
The character is moved to the [K3: SR1: T2] state, No. 5, and when you press KSR again, the character is moved to the "No: [K3: SR2: T2] state, No. 4". .

When the KSR key is pressed in the state where the character (s) has been generated, it is transferred to "Z: [K3: Basis: T2] state, No. 1" by the above-mentioned cyclic structure, and when KT is pressed in this situation “Sa: [K
3: Basis: T1] state, transitioned to 0 ”.
If you press KT with (zo) being generated, it will be transferred to “so: [K3: SR2: T1] state, number 3” due to the circular structure described above, and if you press the KSR key in this situation, “sa: [ K3: Basis: T1], transferred to No. 0 ”.

Since the remaining characters are also formed by the transition process shown in FIG. 6, a detailed description thereof will be omitted.

3) Third method This method is used for inputting the characters corresponding to K5 (Na line), K7 (Ma line) and K9 (La line) in FIG. 1, and refer to the chart of FIG. For example, each set consists of 5 characters, which is defined as "5 states". The display of each state uses the coordinate expression method used for the spatial coordinates, and FIG. 7 presents a transition diagram of the states by key input. The function that defines the transition of the state presented in this transition diagram is defined as the third transition function.
When you press the basic character key corresponding to “Ma” or “La”, the third transfer function is called, and the characters corresponding to K5, K7, and K9 are the third character.
Input is made by the transition of the states of FIG. 7 based on the transfer function. If a character that does not correspond to K5, K7, or K9 is input while the third transfer function is being called (that is, if another basic character that is not Nama, etc. is input), as described above. This corresponds to the input of a basic character for inputting another character, and the first transfer function and the second transfer function are called respectively. In addition, since there is no character corresponding to T2 and T3 in this method, the KT key is not applied.

Here, 0 to 4 inside the circle are numbers representing each case of "5 states", and the coordinates showing the state are presented for each number. Explaining the input example of any character (for example, “RO”) by using this transition diagram, once the KSR is once performed with the basic character “La: [K9: Basis: T1] state, No. 0” corresponding to this character. If you press it, it will be transferred to “re: [K3: SR1: T1] state, No.1”, and if you press KSR again in this situation, it will be in “ro: [K3: SR2: T1] state,
A character (ro) is generated by being transferred to "2".

When the KSR key is pressed in the state in which the character (RO) has been generated, the state is changed to "R: [K9: Basis: T1] state, No. 0" by the above-mentioned cyclic structure.

Since the remaining characters are also formed by the transition process shown in FIG. 7, a detailed description thereof will be omitted.

The embodiments of the present invention will be generalized and summarized with reference to the flowchart presented in FIG.

First step: a step of selecting and inputting a basic character corresponding to a clean sound in the row of the line to which the desired character belongs, which is a basic operation item for inputting all characters.

Second step: a step in which a transfer function necessary for generating an input character is called, and a corresponding transfer function, that is, a first transfer function or a second transfer function, is generated by pressing a basic character key on which a selected basic character is arranged. The transfer function and the third transfer function are called.

Step 3: If the input character is the selected basic character, return to the first step to input another character, and if the input character is the non-selected basic character, KSL key, K
When the input character is generated by the called transfer function using the SR key and the KT key, when the KSL key, the KSR key, and the KT key are pressed in combination, the input character is changed by the called transfer function. Is generated.

Fourth step: This step is to perform the operation of the first step again (to return to the first step) for the input of another character when the input of one character is completed through the above steps. However, the input of another character goes through the first step, the second step, and the third step again.

The preferred embodiments of the present invention have been described above in detail, but those skilled in the art to which the present invention pertains have ordinary skill in the art. It can be seen that various modifications and implementations can be made without departing from the spirit of the idea. Therefore, modifications of the above-described embodiments of the present invention do not depart from the technology of the present invention.
Further, although the embodiment of the present invention has been described based on the hiragana, the input character mode conversion to katakana is performed by using the "Kana" key of the hiragana and katakana input selection keys shown in FIG. , Katakana characters can be input in the same manner as the above-mentioned principle.

[0065]

The present invention has the following effects. Conventionally, the number of keys used differs depending on the character,
The number of times the key button is pressed varies depending on the character. However, in the present invention, in order to input one character, only three keys (basic character key corresponding to the input character, SL (KSR) key, KT key) may be operated. Furthermore, because the number of keys required to enter one character is three, the number of times the key button is pressed to enter characters can be significantly reduced, making it extremely convenient to use the character input function using a wireless terminal. Became.
