SUMMARY OF THE INVENTION A method and apparatus for inputting Japanese characters using 16 keys according to the present invention determine a dedicated keyboard having 16 keys and a key code of a key input from the keyboard and pass it to an application. An operating system (OS), key input determination processing for determining which key has been input as a function deployment of the OS, and fixed time determination processing for checking the time between the previous input and the current input. A key information transmission process of passing key information to the application side, and "A, I, U, E,
For the input of "O" and the consonant "N", the key code of a single key that can be input with the same keystroke is input. Assign the same key as the primary key code of the composite key, and assign the same key as the primary key code of the composite key, and assign the same key to the consonants that are used less frequently than other consonants. The sub-key code of the composite key is input by continuously inputting those keys.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is for inputting Japanese by using the following 16 keys on the premise that Japanese input is performed by using Roman-Kana conversion. The 16 keys are laid out in the following arrangement. L / Q M / XY / J R / C W / VP / FA IUOK / GS / ZT / DN / H / B Vowels "A, I, U, E, O ”And consonant”
The input of "N" can be performed by tapping as it is (these keys are defined as the key code of a single key), and the input of "L, M, Y, R, W, P, K, S, T, H" Even for consonants that are frequently used for input, a keystroke input can be performed by leaving an interval of a predetermined time or longer as the same key code (these keys are defined as the primary key code of the composite key).

"Q, X, J, C, V, F, G, Z, D,
B ”is used less frequently than the other consonants, so these keys are used as“ L, M, Y,
This is realized by assigning the same key as the R, W, P, K, S, T, H "keys and continuously inputting those keys within a certain time interval. For example, as another letter of" L " To enter the assigned "G", enter "K" + "K" within a fixed time (these keys are defined as sub-key codes of the composite key).

Since all alphabets from A to Z can be input by these operations, conversion of Roman alphabet to kana can be realized, and alphabet input can be performed at the same time.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a method and an apparatus for inputting Japanese characters using 16 keys according to the present invention.

Referring to FIG. 1, the embodiment of the present invention has the following configuration. A dedicated keyboard 1 having 16 keys arranged in the layout, and an operating system (O) for determining a key code of a key input from the keyboard 1 and passing it to the application 3
S) 2, key input determination processing 21 for determining which key has been input as a function deployment of the OS 2, fixed time determination processing 22 for checking the time between the previous input and the current input, and the application 3 side And key information transmission processing 23 for passing key information to the key information.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIG.

FIG. 2 is a flow chart showing the operation of one embodiment of a method and an apparatus for inputting Japanese characters using 16 keys according to the present invention.

First, the user presses one of the 16 keys of the dedicated keyboard 1 to input a Roman character (step S1). Next, which key has been input is determined by the key input determination processing 21 to determine whether or not the key is a composite key to be continuously input (step S2). Since the single keys "A, I, U, E, O, N" which are not to be continuously input can be output with the key codes of the single keys as they are (step S10), they are passed to the key information transmission processing 23 (step S11).

The compound key to be continuously input is ""
L / Q, M / X, Y / J, R / C, W / V, P / F, K
/ G, S / Z, T / D, H / B "(step S2), it is determined whether or not a predetermined time (t1) has elapsed since the last keystroke.
2 (step S3), and if the predetermined time (t1) has not elapsed, it is determined by the key input determination processing 21 whether the key input this time is the same as the key input last time, and the key is not the same composite key. (Step S6) is the primary key code "L, M, Y,
Since it can be output as one of the primary key codes of the composite key of R, W, P, K, S, T, H "(step S9), it is passed to the key information transmission processing 23 (step S11). The key input determination processing 21 determines whether the key is the same as the previously input key, and if the key is the same (step S6), the sub-key code "Q, X, J, C, V, F, G, Z,
Since it can be output as one of the sub key codes of the composite key of D, B "(step S8), it is passed to the key information transmission processing 23 (step S11).

If the predetermined time (t1) has elapsed (step S3), it is determined whether or not a predetermined time (t1) has elapsed from the current keystroke.
From step 2 (step S4), the composite key is not determined until a predetermined time (t1) has elapsed from the current keystroke. If there is no next keystroke, the main key code of the composite key struck this time is "L". , M, Y, R, W, P,
Since it can be output as one of the primary key codes of the composite key of "K, S, T, H" (step S7), it is passed to the key information transmission processing 23 (step S11).

The key information passed to the key information transmission processing 23 (step S11) is sent to the application 3 side.

By repeating these operations, it is possible to sequentially input Roman characters.

As another embodiment different from the above embodiment, an embodiment in which the output of the primary key code and the output of the sub key code of the composite key are reversed is possible. In this case, FIG.
Steps S7 and S9 of the flow chart showing the operation of one embodiment of the method and apparatus for inputting Japanese characters using 16 keys of the present invention, output of the sub-key code of the composite key, and step S8 are the primary key of the composite key. It turns into outputting code.

The arrangement of the 16 keys can be realized by software on a normal JIS full keyboard, in which case a dedicated keyboard is not required. In addition, since it is not necessary to press two or more keys at the same time for keying, the position of the 16 keys can be devised so that a one-handed keyboard or a disabled person can be used.

The recording medium 4 on which the processing program as described above is recorded can be executed by the OS 2.

[0025]

As described above, the method and apparatus for inputting Japanese characters using 16 keys according to the present invention have the first advantage that it is easier to learn the arrangement of the JIS full keyboard as in the prior art. .

The reason is that Japanese and English characters can be input by learning 16 keys.

The second effect is that the key arrangement is easy to remember.

The reason is that the key arrangement is regular when viewed as Roman characters.

The third effect is that the input efficiency is improved.

The reason is that vowels and consonants are divided into left and right sides, so that left and right alternate keys are easily formed.

The fourth effect is that it is possible to easily search without memorizing the arrangement.

The reason is that the number of keys is as small as 16 keys.

The fifth effect is that the input speed can be increased.

The reason is that, since the keys are arranged in two stages, touch typing is easy and the moving distance of the finger is short.

The sixth effect is that there is no need to learn a new input method.

The reason for this is to use the same Roman alphabet Kana conversion as before.
