Abstract

PURPOSE:To make efficient operation possible by providing a kana (Japanese syllabary) keyboard by which four small kana letters [ya], [yu], [yo], [tsu] and other large kana letters excepting the four small letters are inputted when the key is depressed separately. CONSTITUTION:In a kana keyboard not shown in the figure, four small kana letters [ya], [yu], [yo], [tsu] and other large kana letters excepting the four small letters are inputted when the key is depressed separately. When a shift key is depressed simultaneously with the key, large letters of above-mentioned four letters and small letters of other kana letters are inputted. By this way, by changing handling of small letters and large letters according to frequency of appearance of above-mentioned four letters, efficiency of inputting of Japanese can be improved without changing geometrical arrangement of conventional letter keyboard.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Japanese language input device, and more particularly to a device that improves the efficiency of Japanese language input on an input keyboard of an information processing device.

[Conventional technology]

Conventionally, in this type of Japanese input device, when inputting kana characters of the Japanese syllabary, when a key is pressed individually for all characters, K is input as a capital letter, and one specific key (hereinafter referred to as the shift key) is input. It had a kana keyboard with a structure that allowed Japanese input by inputting lowercase letters when pressed at the same time.

[Problem that the invention seeks to solve]

In the conventional Japanese input device described above, all kana lowercase letters can only be input by using the shift key in combination, regardless of the frequency of appearance of each character in Japanese. However, in recent Japanese, Chinese words and loan words are used relatively frequently, resulting in the frequent use of substitutions and consonants, resulting in the words ``ya'', ``yu'', ``yo'', [''tsu ” appear very frequently as lowercase letters,
With conventional keyboards, the frequency of pressing the shift key is affected.

For this reason, conventional devices have the disadvantage that the efficiency of inputting Japanese into an information processing device is low.

SUMMARY OF THE INVENTION An object of the present invention is to provide a Japanese language input device that solves the above-mentioned drawbacks and can be operated efficiently.

[Means for solving problems]

The configuration of the Japanese input device of the present invention is such that when a single key is pressed, the four lowercase kana characters "ya", "yu", "yo", and "tsu" and the four lowercase letters The keyboard has a kana keyboard in which the four uppercase letters and the lowercase letters of the other kana letters are input when the shift key is pressed at the same time as the above-mentioned key. Features.

〔Example〕

Next, embodiments of the present invention will be described using example sentences.

(Ever since life began on Earth, only the strong have survived due to the law of natural selection.) In the example sentence above, the words ``ya'', ``yu'', ``yo'', and ``tsu'' are used. The six underlined parts belong to the four characters of ``, and four of them are sounds or consonants.

Therefore, with conventional Japanese input devices, including voiced marks and punctuation marks, input requires 57 character keystrokes and 4 shift keystrokes, a total of 61 keystrokes.

In the Japanese input device of this embodiment, the number of keystrokes of the shift key is reduced to two, making it possible to input the same sentence with 59 keystrokes, achieving a high efficiency of over 3% in the number of keystrokes. Furthermore, it is necessary to press the shift key and the character key at the same time; for example, in the JIS layout, the little finger and index finger are forced to be in an extended position, which reduces the burden on the hand more than the reduction in the number of keystrokes.

〔Effect of the invention〕

As explained above, according to the present invention, there is no need to change the geometric arrangement of the conventional letter keyboard, and the four characters "ya", "yu", "yo", and "tsu" can be used in Japanese. By switching the format of lowercase and uppercase letters according to their frequency of occurrence in a word, the effect of 1. improving the efficiency of Japanese input can be obtained.

Claims (1)

[Claims] If you press the key alone, it will be "ya", "yu", "yo".
, ``tsu'' and the other uppercase kana characters other than the four lowercase letters are input, and when the shift key is pressed at the same time as the above key, the four uppercase letters and the other uppercase letters are input. 1. A Japanese language input device comprising a kana keyboard into which lowercase kana characters are input.
