Description

Description: TECHNICAL FIELD The present invention relates to a keyboard of a Japanese word processor of kana-kanji conversion system, and particularly, a key for inputting kana and sentence symbols (hereinafter referred to as a character input key). The present invention relates to a keyboard that is rationally arranged so that input operations can be performed easily and quickly.

(Prior Art) In a word processor, various key arrangements have been conventionally devised because the operability of keys dominates the spelling input speed.

For example, in the JIS kana layout, 48 character input keys are arranged in four rows vertically, and one kana is input with one character input key. However, the number of characters required for spelling kana is: The number of kana that is necessary for modern kana has reached 81, and it is not possible to assign all of them to one character input key.
You can press the shift key and the character input key (in this case, Yu, Yo, Tsu) to which another kana has already been assigned at the same time, and the kana (for example, , Da, or semi-voiced sound (for example,
Kana is the corresponding Kiyone (in this case,
By pressing the character input key and the voiced sound key or the semi-voiced sound point key at the same time, the respective characters are input.

For this reason, each finger has a large number of character input keys and the movement of the fingers is heavy. Especially, it places a heavy burden on the little finger which is difficult to move in the lateral direction. You need to move the whole flat back and forth in your hand to push, each finger for the frequency of Kana appearance,
There are problems such as the usage rate of each stage is not appropriate and the deviation is large, and the rate of using the same hand continuously is high. Above all,
Often when jumping over columns and pressing continuously (from the 1st stage to the 3rd or 4th stage, from the 2nd stage to the 4th stage, and vice versa), the function key is the character input key. Since it is placed around or away from the keyboard of, the palm of the hand is moved greatly to operate the function keys, and each finger is moved to the correct position (home position) on the keyboard of the character input keys. The operability is extremely poor due to the large loss of time for returning and the fact that the thumb, which is sluggish, is also responsible for multiple function keys.

Therefore, in order to improve these drawbacks, an array (generally referred to as a thumb shift array) has been devised which does not use the character input keys in the fourth row and introduces a simultaneous pressing key system.

(Problems to be solved by the invention) However, even in the above-mentioned thumb shift arrangement, the number of times of inputting the character input keys accompanied by the operation of the simultaneous pressing keys by the slow-moving thumb or little finger is the total number of input times of the character input keys. Of 3
Since it occupies 8%, rhythmical is impeded by high-speed input, and it is easy to make an input error due to the timing difference of the simultaneous pressing keys, especially with the thumb of the same finger as the character input key. When pressing the simultaneous push keys, it is easy to adopt an easy method of hitting the entire palm down to the keyboard surface, which is easier than pressing only the finger without changing the distance between the palm and the keyboard. The lack of quickness, rhythmic input operation was not possible, and although improvement was achieved by not using the 4th step for the character input key, the drawbacks of the simultaneous pressing key method were newly added. There were still many drawbacks.

(Means for Solving the Problems) The present invention is a keyboard of a Japanese word processor made in view of the above drawbacks, and has two groups of character input keys which the left and right hands handle. Are arranged in two rows above and below and five rows left and right for each group, and the keys of the two groups are for inputting kana or text symbols only when two keys are pressed to the left and right respectively. It is characterized by being.

(Operation) When two character input keys of two groups which the left and right hands handle are aligned left and right, and two keys are pressed, only at that time, a kana, a sentence symbol, etc. are input.

(Examples) Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a keyboard according to an embodiment of the present invention.
It is applied to a widely used keyboard with one key and one bar-shaped key below.

On the second and third rows of this keyboard, the character input key A
(○) and auxiliary key B (⋄) are arranged, and by pressing one of the 11 keys that the fingers of the left and right hands hold, kana, text symbols, and numbers And one of a total of 121 basic functions is input.

Also, a thumb key A'for inputting one of the basic functions is arranged at the bottom. In this case, the thumb is 1
It is only responsible for each key. Therefore, unlike the conventional arrangement in which the thumb is in charge of four or more keys, the overall operation speed is not reduced by the blunt movement of the thumb.

Furthermore, a total of 24 general function keys C (indicated by □) are arranged in the first stage, two at both ends of the third stage, 12 in the fourth stage, and a total of 24. By pressing, you can enter any one of the 24 general functions.

The embodiment shown in FIG. 2 is an example of the arrangement of the character input key A and the auxiliary key B. In this keyboard layout, the character input key A and the auxiliary key B are arranged in two rows.

FIG. 4 shows an example of a display based on the key layout shown in FIG. In this case, the auxiliary keys in the rightmost column are basic functions, such as those that allow the user to arbitrarily set other functions, paragraphs, line breaks and spaces, delete one character, and the last one character of the kana during input. Delete, delete all ... Delete all of the kana being entered. Furthermore, the correspondence with numbers and basic functions is also shown.

According to the statistics of the frequency of appearance of kana and character symbols in Japanese information shown in "Survey Report on Standardization of Japanese Information Processing" published by The Japan Electronic Industry Development Association (March 1983), In the figure display, the frequency of key usage is roughly 18% for the index finger and 15% for the middle finger for the left and right hands.
The ring finger was 10% and the little finger was 7%. According to such a combination, each finger has a load level corresponding to strength and smoothness of movement, and fatigue is not biased to a specific finger. Furthermore, based on the Kana filing frequency statistics in Japanese information shown in the above-mentioned “Survey and Research Report on Standardization of Japanese Information Processing” above, the key operations in the general and lower rows are
%, And the key operation on the upper row was 28%. For this reason, most of the operations can be performed with only the keys on the lower row, and the amount of movement of the front and rear of the fingertip is extremely small. Further, in the present embodiment, since the auxiliary key B is arranged at a position where it is easy to press, it is not necessary to move the palm at all for numbers and basic functions like the kana, and rhythmic operation can be performed, resulting in smooth and smooth operation as a whole. Easy input operation is possible.

FIG. 3 shows an example of the arrangement of the general function keys C. Further, in the figure, each symbol indicates the following function.

Further, shift keys D (indicated by ▽) are arranged on the left and right of the first stage, and while any one of them is being pressed, the character input key A, the auxiliary key B and the general function key C are held.
46 by pressing any one of
You can enter any one of the general functions of the species.
Then, by pressing the key A ′ while pressing the shift key D, it is possible to newly input one kind of basic function.

FIG. 5 shows an example of arrangement of the general function keys and the basic function keys. It should be noted that the items indicated by (1) are for which the user can set any general function.
Further, in FIG. 5, each symbol indicates the following function.

That is, de ... Decimal tab, previous p ... Previous page, next P
... next page, top ... top display, bottom ... bottom display, P ... page call, take ... cancel, left ... left end display, right ... right end display, all ... full text target, co ... copy.

In the present invention, when pressing the left and right character input keys and the auxiliary key, it is not necessary to sequentially press the right and left keys in order, and even if the left and right keys are pressed simultaneously,
The keys may be pressed sequentially in the right order, and when they are pressed sequentially, even if there is a time interval between the pressing time of the first key and the pressing time of the next key, or It is characterized in that the same result can be obtained even without it.

Further, in the present invention, the keys are not limited to the shape of a keyboard in which each key is linear and arranged on the same plane as in a conventional keyboard for inputting data processors, and a key group for the right hand is used. Align the keys horizontally and vertically to accommodate the difference in the length of each finger and the difference in how the tips of the fingers fall when the fingers are bent downwards, with a gap between the keys of the left hand. It is included in the shape of the key arrangement in which the physical arrangement of the keys is changed such as moving.

Further, in addition to the above embodiment, the auxiliary key B of the second stage and the third auxiliary key B
The general function keys C of the columns may be replaced with each other, and the character input keys and the auxiliary keys may be arranged in columns other than the second and third columns. Also, the arrangement of each character input key and each auxiliary key, and the kana obtained by the combination of the character input key and auxiliary key, such as text symbols, numbers and basic functions, and the arrangement of general function keys are other than those illustrated here. Can be set.

(Effects) As described above, the keyboard according to the present invention has two groups of character input keys that the left and right hands handle, and the character input keys are arranged in two groups of upper and lower and five rows of left and right for each group. These two groups of keys are used to input kana or text symbols only when two keys are pressed, one on the left and one on the right. All of these keys can be pressed without moving them, without changing the relative position of the fingertips and keys due to unnecessary movement of the palm.

Also, since the left and right keys can be pressed each other or simultaneously, basic functions such as letters and text symbols can be entered rhythmically, and the input speed is much higher than with conventional keyboard layouts. can get. In addition, since it is not necessary to perform jumping and pushing every other steps with the same hand, it is possible to reduce input mistakes and reduce fatigue, and a smooth operation is possible as a whole.

Further, since the character input keys can be arranged according to the frequency of use, a load corresponding to the strength of each finger can be applied, and an operation in which fatigue is not biased to a specific finger is possible.
