Description

The present invention relates to a key input device used for an office computer, a word processor, and the like.

[Prior Art] Conventionally, in a key input device such as an office computer or a word processor, Japanese characters such as “kya”, “kyu”, and “kyo” have been used in order to more easily and quickly input Japanese characters in Roman characters. It is known that subscripts “ャ”, “ュ”, and “ョ”, which represent the tongue of, are assigned to keys such as Q, X, and L that are not used for Japanese input in Roman characters.

[Problem to be Solved by the Invention] In such a conventional key input device, keys such as Q, X, L, etc.
The letters “ュ” and “ョ” are assigned.

Therefore, the key positions of “ャ”, “ュ”, and “ョ” are inconsistent, especially for an unskilled operator. This was causing incorrect input.

Despite the presence of the keys "A", "U", and "Y", character input on a line is performed by a consonant key + a vowel key.

Problems of the first invention, Y _A vowel block divides the keyboard into vowel block and consonant block, Y _U, by the inclusion of Y _O key, Y _A, Y _U, and usually vowel key Y _O key In the same way, it is possible to input a repetitive sound simply by operating.

A second object of the present invention is to provide Y _A ,
Y _U, by combined alphabetic character keys that are not used for Japanese input in Y _O key input contracted sound without increasing the number of keys is to allow easier.

A third object of the present invention is to provide Y _A ,
The object of the present invention is to improve the efficiency of character input by enabling the character input of the “Y” line by simply operating the Y _U and Y _O keys.

[Means for Solving the Problems] A key input device according to a first invention is a vowel block including a key corresponding to a vowel input and a consonant block including a key corresponding to a consonant input in a Japanese input keyboard in Roman characters. Divided into two blocks on the left and right
It contains the keys of Y _A , Y _U , and Y _O.

In the key input device of the second invention, the Y _A , Y _U , and Y _O keys are also used as English character keys not used for Japanese input.

The third key input device of the present invention, the Y _A, Y _U, discrimination discriminating means for discriminating whether or not consonant key is operated in response to Y _O key, consonant key is operated by the discrimination means When it is determined that the consonant key is not operated, a capital letter corresponding to the consonant is input.

[Operation] The key input device according to the first aspect of the invention provides a vowel block with Y _A ,
Y _U, so was the inclusion of Y _O keys, consonant keys + Y _A, Y _U, Y by _O key can do input contracted sound, can reduce the key number of operations during key input, further Y _A in the contracted sound input , Y _U and Y _O keys can be operated in the same manner as ordinary vowel keys, so that the burden of key input can be reduced.

Key input device of the second invention, Y _A, Y _U contained in a vowel block, Y by combined alphabetic character keys that are not used for Japanese input in _O key, input of contracted sound without increasing the number of keys It is possible to provide a keyboard which can be easily operated.

The third key input device of the invention is, Y _A contained in vowel block, Y _U, because you perform capitalization corresponding to whether the contracted sound or diphthong consonants key is operated in response to Y _O key If you want to input a repetitive sound, you only have to operate the Y _A , Y _U , and Y _O keys following the consonant key. Since it is only necessary to operate the Y _A , Y _U , and Y _O keys, the number of key operations is reduced, thereby reducing the burden of key input and preventing erroneous input.

Embodiment An embodiment will be described below with reference to FIGS. 1 to 4.

Configuration FIG. 1 shows a key arrangement state on a keyboard.
That is, the keys on the keyboard 1 can be consonants in Japanese input in Roman characters, ▲ [F] ▼, ▲ [W] ▼,
… [A] ▼, ▲ [I] ▼, ▲ [U] which can be vowels in consonant block BK1 including ▲ [Z] ▼, ▲ [G] ▼ keys (consonant keys) and Japanese input in Roman characters
It is divided into left and right two blocks: ▼, ▲ [E] ▼, ▲ [O] ▼ keys (vowel keys) and a vowel block BK2 including keys other than the keys included in the consonant block BK1. Then, of the keys included in the vowel block BK2, other keys except the vowel key, that is, ▲ [Y] ▼, ▲ [X]
Characters unique to Japanese corresponding to the ▼, ▲ [J] ▼, ▲ [L] ▼, ▲ [C] ▼ keys, “Y _A (ya)”, “Y _U (yu)”, “Y _O
(ョ) ”,“ ン ”, and“ ッ ”. Others
The vowel block BK2 includes a [Q] key and a kana / alphabet conversion key.

FIG. 2 is a block circuit diagram showing a basic configuration of the key input device.

The CPU 11 fetches a key code output from the key input unit 12 corresponding to the operation key, and controls various operations of the key input device according to a key processing program stored in the ROM 13. That is, the CPU 11 converts the input key code into the corresponding character code using the alphabet table 14 in the alphabet input mode, and converts the key code into the katakana input mode in which the katakana input is performed by the Roman characters. When a key such as ▲ [K] ▼, ▲ [S] ▼, ▲ [T] ▼, ▲ [N] ▼ is operated to input a consonant such as a line, the key code is stored in the consonant memory 15.
Transfer to evacuation. In addition, in the kana input mode, the CPU 11 operates the character keys included in the vowel block BK2 of the keyboard 1 (in addition to the normal vowel keys, ▲ [Y _A ] ▼), ▲
[Y _U ] ▼, ▲ [Y _O ] ▼, and “N” and “T” keys are included. (Hereinafter, referred to as a vowel block key), Roman / kana conversion is performed using the exchange table 16. The CPU 11 reads the character code (alphabet) read from the alphabet table 14 or the conversion table 16.
After setting the character code (Katakana) read out from the internal register RT, the character code is transmitted as input data.

Incidentally, the key code of the key that is included in the consonant blocks BK1 keyboard 1 in the alphabet table 14 is represented by a _{k 1, k 2 ...... k 15} , also the key code of the key included in the vowel block BK2 is K ₁ , K ₂ ... K ₁₁ are represented. Then, the conversion table 16 corresponding to the key code k _1, k ₂ ...... k ₁₅ keys the horizontal direction is included in the consonant blocks BK1, also its longitudinal axis is included in the vowel block BK2 Key codes K ₁ , K
Which corresponds to _2, K ₃ ...... K _11.

Operation FIG. 3 is a flowchart showing the overall operation, and is started each time one key is operated.

First, the input mode is determined (step S
1). Now, when the mode is set to the alphabet input mode, the character code corresponding to the input key code is read out from the alphabet table 14 and read by the CPU 11.
After that, the stored contents are output (steps S2 to S4).

Also, when set to Kana input mode,
First, the type of the operation key is checked (step S5).

Now, it is assumed that the ▲ [K] ▼ key and the ▲ [A] ▼ key (that is, a consonant key + a vowel key) have been operated, for example, to input the character “ka”. In this case, first, the consonant key is operated.
Proceeding to S13, the key code corresponding to the operated consonant key is fetched and transferred to the consonant memory 15 and saved. Next, when the vowel key is operated, the process proceeds to step S6, and the type of the operation key is checked. In this case, the process proceeds to step S11,
The key code saved in the consonant memory 15 is read out and given to the conversion table 16 together with the key code of the vowel key operated this time.The character code searched by this is read out from the conversion table 16 and stored in the internal register RT of the CPU 11. set.

When the consonant key has not been operated immediately before the operation of the vowel block key, the key code is not stored in the consonant memory 15, so that `` A '', "I", "U",
“E”, “O”, “N”, and “T” are read.

Thereafter, the process proceeds to step S12, where the content of the consonant memory 15 is cleared, and then the content stored in the internal register RT is output (step S4).

Further, when the suffix keys ▲ [YA] ▼, ▲ [YU] ▼, ▲ [YO] ▼ are operated, this is detected in step S6 and the process proceeds to step S7, where the contents stored in the consonant memory 15 are stored. It is determined whether or not the consonant key has been operated immediately before the operation of the subscript key. Now, assuming that the consonant key was not operated immediately before the operation of the suffix subscript key, but only the suffix subscript key was operated, in this case, the process proceeds to step S10, and the capital letter “Y” corresponding to the operation key was used. After reading the character codes of “Y” and “Y” from the conversion table 16 and setting them in the internal register RT of the CPU 11, the stored contents of the internal register RT are output (step S4).

On the other hand, if the consonant suffix key is operated and the consonant key is operated immediately before that, in step S7, the fact is detected, the process proceeds to step S8, and the key code saved in the consonant memory 15 is deleted. The readout and the key code of the suffix key operated this time are given to the conversion table 16 together with the key code of the suffix key operated this time.
And set it in the internal register RT of the CPU 11.
Thereafter, the process proceeds to step S9, where the content of the consonant memory 15 is cleared, and then the content stored in the internal register RT is output (step S4).

Therefore, for example, as shown in FIG.
Capital letter "Y" if only the key
Is input, and if the consonant key of ▲ [K] ▼ is operated and then the subscript key of ▲ [YA] ▼ is operated,
Resonant sound "kya" is input.

Modified Application Examples (1) In the above embodiment, katakana characters are entered in Roman characters, but hiragana characters may be entered. In this case, a Roman character / Hiragana conversion table is provided.

(2) In the above embodiment, characters unique to Japanese input are used.
Y _A , Y _U , Y _O , 、, ッ, but ゆ, 、, 、, ャ, 、,
Any kind of character such as a letter may be used.

[Effects of the Invention] According to the first invention, since the Y _A , Y _U , and Y _O keys are included in the vowel block, the vowel can be input only by the same operation as the normal vowel key, and the number of key operations In addition, the burden on the operator during key input is reduced.

According to the second aspect of the invention, it is possible to provide a keyboard capable of reducing the burden on the operator for inputting the sound without increasing the number of keys.

According to a third aspect of the invention, Y _A, Y _U, Y operation _O key only "Ya" because performed input character is a line, the operator of the burden to reduce the time of key input, erroneous input prevention It also has an effect.
