Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard for an electronic device in which a finger is arranged so that a finger does not accidentally press an adjacent key by extremely reducing the surface area of the key, and an electronic device using these keyboards. It is about.
The electronic device referred to in the present invention is a telephone, an information processing device, a mobile device, a terminal, a communication device including them, a home appliance,
Includes amusement machines and single-purpose devices.

[0002] The present invention provides a keyboard for electronic equipment in which the solar cell is disposed in a space formed between the keyboards by making the surface area of the keyboard extremely small, thereby saving energy of the electronic equipment. The present invention relates to an electronic device using the same.

[0003] The present invention is directed to an electronic device capable of easily and quickly inputting various characters and the like and using a blind touch by using a balance key having a small number of function keys such as 0 to 9 provided in a telephone or the like. The present invention relates to a device keyboard and an electronic device using the keyboard. In particular, portable telephones are capable of inputting characters using a balance key, and thus have come to have substantially the same functions as personal computers.

[0004] Since mobile devices and terminal devices other than mobile phones are required to be small, it is necessary to input characters using a balance key. In the present specification, “characters and the like” means alphabets, katakana, hiragana, character strings composed of kana and kanji, numbers, punctuation marks, symbols, and the like.

[0005]

2. Description of the Related Art Many conventional keyboards have a size substantially equivalent to the size of a finger. Some keyboards are smaller than the size of a finger, but since the size of the electronic device is small, the interval between keys is relatively small. Furthermore, an electronic device with low power consumption, such as a calculator, can be used without replacing the battery by providing a solar battery in a part where the keyboard is not provided.

FIG. 15 is a diagram showing the number of each key provided on a conventional telephone or the like and character information corresponding to the number. In FIG. 15, the balance key is at least
"0, 1, 2, 3, ..., 9", "*" and "@"
And twelve.

[0007] The key on the telephone is
"A line", "ka line", ..., "8", "ya line", "9", "ra line", "0", "wa, wo, n" in order from "1".
Is assigned. In the alphabet, as shown in FIG. 15, three to four characters are assigned to one key. So if you want to hit one character,
"Oh, ka, sa, ta, ..., wa" can be done only once,
"Oh, this, that ..." had to hit the same key five times.

[0008]

A normal keyboard is:
Because it is made to fit the size of your finger, if you move your finger correctly, you can type in accurate characters without looking at the keyboard. However, even a person who can perform a blind touch may press two keys when the arrangement of the fingers is slightly shifted. Those who are practicing blind touch will often press two keys at the same time,
You will see the key below. As a result, blind touch may not be possible. Since the conventional keyboard is manufactured so as to substantially match the size of the finger, there is a problem that the left, right, front and rear keys are pressed by mistake.

[0009] In recent years, portable telephones, mobile devices, and the like have been reduced in size and have almost the same functions as computers, and the Internet and e-mail have become available. The Internet and e-mail can obtain character information and image information. Conversely, when sending an e-mail from a mobile phone or the like, or when accessing desired information via the Internet, it is necessary to input characters. However, in the conventional character input method using the balance key, when one character is hit, it is necessary to hit once to a maximum of five times. In addition, the conventional character input method is as shown in FIG.
The characters in the fifth row shown in (1) have the problem that the number of strokes must be counted one by one or input while looking at the display.

[0010] In order to solve the above problems, the present invention is to make the surface area of the key extremely smaller than the size of the finger, so that even if the key deviates more than half from the fingertip, it can be applied to the left, right, front and rear keys. The size of the key should not be too large. A keyboard composed of such keys,
There is a lot of space between each key. Therefore, by providing a solar cell in the space, it can be used as a main power supply or a sub power supply of the electronic device.

Another object of the present invention is to make it possible to input characters on a small device such as a portable device using a balance key. According to the present invention, one character or a symbol can be struck by combining the first stroke and the second stroke from “0, 1, 2, 3,..., 9”. That is, according to the present invention, characters and the like can be easily assigned by assigning characters and the like to 100 locations of 10 × 10 with “0, 1, 2, 3,..., 9” taken on the vertical axis and the horizontal axis. In addition, it is possible to input quickly and to perform a blind touch. An object of the present invention is to provide a keyboard for electronic devices that has solved the above-described problems, and an electronic device that uses these keyboards.

FIG. 2 shows a first embodiment of the present invention.
It is a figure for explaining arrangement of all the characters and symbols arranged in a place. FIG. 3 is a diagram for explaining a method of inputting numbers and characters of a balance key according to the first embodiment of the present invention.

In FIG. 1, the keys are represented by circles, and are considerably narrower than the width of the fingertip. In addition, the keys are arranged to be separated from each other by several times the area of the keys. For example, the key diameter is between 1mm and 4mm,
It is at most about 5 mm or less. The shape of the key may be a square or an ellipse in addition to a circle when viewed from above, but may be a flat or gentle projection when viewed from the side.

The upper surface of the key of the present invention does not have a conventional flat or concave surface, but can be provided with a projection for stimulating a fingertip pot. Therefore, it is desirable to select the shape of the projection on the key according to the usage time of the keyboard. A key with a projection stimulates the acupressure point of the finger to not only activate the brain and improve blood circulation but also relieve stress. Further, the degree of protrusion of the key shown in FIG. 1 can be changed by a numeral. That is, by changing the height and shape of the projections by the numbers, the operator can easily determine which finger is touching which number key without looking at the keys.

Next, a method of inputting characters of the balance key will be described. In FIG. 2, the vertical axis indicates “0, 1, 2, 3,.
., 9 "on the horizontal axis, and" 0, 1, 2, 3,...
9 "is taken to form a 10 × 10 matrix, in which characters and symbols shown in FIG. 2 are assigned. In FIG. 3, an input method is assigned to one key “0, 1, 2, 3,..., 9”. In FIG. 1, the characters arranged to the left of the numbers are the input method. For example, the "number" in "0" is a numeric input, the "yomi" in the upper left of "1" is the kana conversion, and the "head" in the upper left of "2" is
The head-to-head conversion (to be described later), the upper left “*” of “3” is a special case conversion (to be described later), the upper left “piece” of “4” is katakana input, and the upper left “hira” of “5” is Hiragana input, “6” upper left “notation” is symbol input, “7” upper left “English” is alphabet input, “8” upper left “change” is change input,
“Assist” at the upper left of “9” means an input of an assist sword.

As can be seen from the assignment table of the balance key of FIG. 1 and the characters and the like of FIG. 2, "K, S, T, N, H, M" are displayed below the balance key numbers "1 to 9". , Y, R, W ". In addition, the number "1 to 5" of the balance key
"A, I, U, E, O" are arranged in the lower part. Further, other alphabets are assigned to the lower right of the vacant keys having the numbers "1 to 9" of the balance key. The arrangement of the right, middle, and left of the alphabet can be reversed, or the arrangement of the other alphabets can be arbitrarily determined.

As can be seen from the assignment table of the balance key of FIG. 1 and the characters and the like of FIG. 2, "A, I, U, D, E" is placed on the left of the keys of the numbers "1 to 5" of the balance key. Is arranged. In addition, the key of the number "1" of the balance key
The key of "f line", the key of the number "2" is "sa line", the key of the number "3" is "ta line", the key of the number "4" is
"Na line", the key of the number "5", "C line", the key of the number "6", "ma line", the key of the number "7",
The key of “Y” and the number “8” are assigned “La”, and the key of the number “9” is assigned “W” and “N”, respectively.

As can be seen from the balance table of the balance key of FIG. 1 and the characters and the like of FIG. 2, the keys of the balance keys of numbers "7 and 8" include a voiced sound "" or a semi-voiced sound "°" and a numeral " Keys 2 through 5 include punctuation marks and the numbers 0, 1, 2,
Symbols are arranged at the keys of "3, ..., 9". In the arrangement, the positions of voiced and semi-voiced sounds, the positions of punctuation marks, or the positions of symbols can be arbitrarily changed. Also, the arrangement of the symbols and punctuation marks can be arbitrarily changed to a position where main characters are vacant.

Next, a method of inputting characters and the like will be described with reference to FIGS. For example, the input method of characters and the like corresponds to the numbers as shown in FIG. 3, and is determined by the first stroke. In the present invention, one character is normally input by two strokes, but only an input method of characters or the like is determined by one stroke with an exception.

The input of an exceptional pseudonym is an exceptional pseudonym that does not become one pseudonym with two letters of the alphabet. That is, "A, I, U, D, O" is a pseudonym of an exception in which characters can be typed with only one key. In the present invention, by typing "0" and "1", "A" is obtained. Become. As shown in FIG. 1, four characters are displayed on the keys of “6, 7, 8, 9” for the input of the exceptional pseudonyms “@”, “″”, “°”, “n”. Then, "0" is hit on the first shot, and the key on which the character or the voiced sound or semi-voiced sound is displayed is hit on the second shot.

As shown in FIG. 1, four punctuation marks are displayed in the lower row of the key, and "9" is input at the first stroke, and the punctuation marks to be input at the second stroke are displayed. Hit. In the case of a telephone number, a number and a number correspond to each other, but when inputting as a character, the numeral key displayed in the upper center of the key is "0" in the first stroke and the second stroke.
