Description

[Detailed explanation of the idea] (b) Industrial application fields The invention is used in the field of keyboards.

The present invention relates to a keyboard for inputting katakana or hiragana, and more particularly to a keyboard arrangement thereof.

(b) Prior art As a conventional example, there is a JIS standard as shown in Fig. 1.

As shown in the figure, the katakana characters according to this conventional example do not follow the alphabetical order and are irregular. Therefore, one can use such a keyboard after considerable training. It is extremely difficult to use for amateurs other than typists or key operators.

There are also keyboards in which all the 50 syllables are arranged horizontally in Aiueo order. but,
Since the kana are arranged vertically and do not follow the 50-on diagram, it is difficult to find the desired kana right away.

Furthermore, there is a device called Thumb Shift used in Japanese word processors, but similarly, the kana character keys are not arranged according to the vertical 50-on diagram, making it difficult for unskilled users to use. .

(c) Problems to be solved by the invention As mentioned above, all conventional keyboards for inputting kana characters are not arranged in accordance with the vertical 50-on diagram.

Therefore, the purpose of this invention is to use the conventional 4-row keyboard for English characters as is, but for kana characters, use those 4 rows and some of the adjacent rows to follow the 50-on diagram. Configure it in a vine array,
To provide a keyboard that is easy to use even for amateurs and has good operability while maintaining regularity.

(d) Means for solving the problem The above purpose is to write katakana or hiragana characters to each key in four rows of five syllables in each row of clear sounds and one adjacent key next to one of them. This can be achieved by allocating the keys and arranging the entire system according to the 50-tone diagram.

(e) Function The conventional four-row keyboard for English characters has only character keys, excluding function keys, and the overall shape is roughly an inverted trapezoid, and the five vertical syllables of each line of kana characters are arranged on the keyboard. By borrowing and assigning the four vertical column keys above and one key in the adjacent column,
The Japanese 50-on keys fit nicely on the keyboard.

(f) Embodiment A preferred embodiment of the present invention will be explained based on FIGS. 2 and 3.

According to the present invention, in a conventional keyboard with four vertical rows for common use of English letters, the clear tones of kana or hiragana characters in each row of five syllables are adjacent to each key in the four vertical rows and one key among them. The keys are assigned to one key, and the entire key arrangement is arranged according to the 50-tone diagram. One embodiment is shown in FIG. In the illustrated example, row A is at the left end of the keyboard, but it is at the right end, and other rows may be arranged sequentially to the left. Note that although the keys in the four rows are not located vertically in a straight line, they are considered to form a row of keys that are close to each other vertically.

It is preferable that the voiced and semi-voiced sounds are assigned by shifting the clear sound key. Each character is displayed on its assigned keytop. An example of the key layout for voiced and semi-voiced characters is shown in FIG.

Note that the kana characters may be displayed not only on the key top but also in the gaps between the keys in the upper and lower rows.

Further, according to the present invention, since the five syllables per line are spread over two columns on the left and right, the character display for at least two adjacent character lines is made to be identified by different colors and background display. It is preferable.

FIG. 3 is a plan view showing one embodiment of the present invention regarding a key mat.

When applying the present invention to the conventional keyboard shown in Fig. 1, if you want to use the key addresses in the hardware without changing them, if you run a conversion program for the key layout between the two, you will be able to use the same keyboard as the present invention. Key operations can be obtained.

(g) Effects According to the present invention, the katakana or hiragana keys are arranged according to the vertical syllabary while maintaining regularity, so when you want to input the desired kana character, you can quickly enter the corresponding character. It is possible to find the key, and the effect is that the operability is excellent.
