The present invention relates to a keyboard used for office equipment and various control devices.

A keyboard generally used includes a main body, a plurality of character input keys arranged on the upper surface of the main body, and a space bar longer than the character input keys. The conventional keyboard that outputs and displays Hangul characters includes a 2 beol keyboard and a 3 beol keyboard, the conventional 2 beol keyboard distinguishes the phonemes of Hangeul by consonants and vowels. Consonants that follow the vowels as initial consonants are output as final consonants. Therefore, in order to process the characters, the initial, neutral, and final characters must be entered in order, so Ki's letters are typed as 'b' and initial letters 'ㅣ', and characters without initial letter 'ㅇ' and neutral 'ㅓ'. Hitting the finality 'ㅂ' and 'ㅅ' to process the desired character. In other words, two to four hand movements must be sequentially inputted without a disparity in order to input one character, and thus, it is difficult to perform fast typing such as shorthand due to low input speed.

In addition, the space bar of a commonly used keyboard is several times longer than other character input keys, but its function is very simple.

The present invention can be easily used by selectively using both Hangul 2 beol and 3 beol type, it is also possible to use a high speed typing such as shorthand, and to increase the utilization of the space bar to easily arrange special character input keys on the keyboard, The purpose is to provide a keyboard that can be easily used by the general public.

The object of the present invention is a keyboard comprising a main body, a plurality of character input keys arranged on the upper surface of the main body, and a space bar longer than the character input key, wherein the space bar is divided into a plurality of subkeys, Each subkey is solved by a keyboard characterized in that it has a function as a character input key and a function as a space bar. In this case, each of the sub-keys can be used as a final input key when the 3 beoljak Hangul input, it is preferable that a key that can switch the Hangul input mode from the 2 beoljak to 3 beolsik. In addition, when the 3 beoljak Hangul input mode is switched, each of the sub-keys, it is advantageous to function as a final key when the initial key and the neutral key of the Hangul is pressed, and to function as a space bar in other cases.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view showing a keyboard according to the present invention. As can be seen in this figure, the keyboard 10 is composed of a main body 13 and a plurality of character input keys 11 arranged on an upper surface of the main body 13 like a normal keyboard. At this time, a large number of subspace keys 1 of the curved type, which are divided by the conventional long space bar and protrude forward, and the distinguishing unit 5 in which the center character input keys 11 are spaced to the left and the right. To have. In addition, special symbol keys (2) to which a final function is further provided for the Hangeul 3 bee type, and a switching key (3) for selectively switching the Hangeul input mode of the 2 bee type and the 3 bee type are installed. It is provided with the indicator 4 for distinguishing.

By the above configuration, when the character input keys 11 of the keyboard 10 are pressed in the double beol type input mode, the keyboard is inputted to the keyboard microprocessor 12 embedded in the main body 13 as shown in FIG. Kiss scan of the character input key 11 through the system memory S1 of the microprocessor 12, the word memory S2, the CPI, the timer count TC, the input / output IO, the clock generator, and the like. The code KSC is generated, and the kisscan code KSC is converted from the keyboard controller 21 of the main board 20 to the system scan code SSC by the keyboard bios and then the main of the main microcomputer 22. Characters are imaged at the same time as the character input key 11 is pressed by conventional components which are changed into actual use codes through the BIOS.

If the user wants to make a high speed typing work such as shorthand using the keyboard 10 while performing document creation and the like in the 2 beol type input mode as described above, pressing the switch key 3 causes the 2 bee type Korean input mode to be 3 bee type Korean input. The mode is switched, and the number 3 part of the indicator light 4 lights up. At this time, the means for controlling the switch key 3 is installed in the hardware in the keyboard microprocessor 12 in the keyboard 10, or by operating the module embedded in the ROM in software.

In addition, the keyboard microprocessor 12 is used to convert the unique kisscan code (KSC) value of each character input key 11 given in the existing double bee type Hangul input mode and the three bee type Hangul input mode. The unique kisscan code (KSC) values of the subspace keys 1 and the special coders 2 are added and installed in hardware.

In addition, when the unique kisscan code (KSC) value is inputted alone or in combination by inputting the character input key 11, the system scan code (SSC) is converted into the system scan code (SSC) through the keyboard controller 21 of the main board 20. A system scan code (SSC) value is added to the keyboard controller 21 of the main board 20 so that the space function and one character or a special character can be output.

In other words, in the 3-Beeul Hangul input mode, the existing consonants of the Hangul 2Beeul keyboard function as the Korean initials, and the existing vowels function as the Korean neutral. In addition, Hangul final input keys are arranged on each of the subspace keys 1 which have been divided into a plurality of conventional long space bars, so that the space function and the Hangul final function can be selectively used. In the present embodiment, four subspace keys 1 are divided on the left and the right to suit the batter. The subkeys are curved to make typing easier. Therefore, it is possible to minimize the complexity of the keyboard by arranging the final keys in the subspace keys 1 without having a new key separately, and is convenient to remember and use. Hangul finalities other than those arranged in the subspace keys (1) are arranged in the conventional special symbol keys (2) to selectively use the special symbol function and the Hangul final function with the special symbol keys (2). To help. In this case, each Hangul finality is arranged at the optimal position for the subspace keys 1 and the special symbol keys 2 in consideration of the frequency of use.

In addition, the subspace keys (1) and the special symbol keys (2) is input as the finality when combined with the initial and neutral in the 3 beol Hangul input mode, and when the input alone, the subspace key (1) and the special symbol keys (2) In contrast to the method of directly displaying a character when the character input key 11 is pressed in the conventional 2 beol Hangul input mode, the unique kiss can of the pressed character input key 11 is pressed when the character input key 11 is pressed. If the code (KSC) is stored in the entrance storage and the character input (11) is returned to its original state, the hardware can be output to the microprocessor (12) so that the kisscan code (KSC) determined to be a combination of characters or individual and special characters can be output. It will be installed by enemy and software. The kisscan code KSC, which is determined to be a combination of characters or a single character and a special character, is output to the keyboard controller 21 of the main board 20 at the same time as the next character input key 11 is pressed. After converted to the scan code (SSC) is converted into the actual use code (AC) through the main device of the main microcomputer 22 to image the characters.

According to the present invention, when one character is input in the 3-better type input mode, the first and second subspace keys (1) and the special symbol keys (2) are pressed together with the initial and neutrality, and the final state corresponding to that is released. This character is entered in combination. As an example of this, in order to hit the character dong, pressing the character input keys 11 of the initial consonant 'c', the neutral 'ㅗ', and the finality 'o' in order, or to quickly type the 'c', Pressing the character input keys 11 at the same time 'ㅗ', 'ㅇ' and then leaving the character input keys 11 in their original state, the combination of space, special characters or Korean characters in the state stored in the temporary memory of the microprocessor 12 After the judgment, the next character input key 11 is pressed and the Keekins code KSC is outputted in the order of combining Korean characters while erasing the contents of the temporary sheltered place, and is changed to the system code SSC. You get a synonym.

In particular, when the subspace key (1) is pressed individually or simultaneously and then released, it is determined that the space function is not a special character or a combination of Korean characters in the temporary memory of the microprocessor 12, and the space is displayed between the special symbols. When you press and release) alone, you get special symbols {,: and so on.

In addition, for the convenience of typing and less typos, a division section (5) is provided that distinguishes the central keys from side to side, allowing you to input complete characters with both initial, neutral, and finality in a single hand movement. Typing is possible.

And when using the Hangul 2 beol type input mode, by pressing the switch key (3) to turn on the number 2 of the indicator (4) can be used like a conventional keyboard. In the case of 2 beol type input mode, since the consonant keys on the keyboard function as both the finality and the initial function, each subspace key 1 does not function as the Korean finality, and each subspace key 1 is used alone. It functions as a space key as usual, but when used together with a key that performs a control function such as a shift key among the character input keys 11, a special statement (for example, α, β, , π) may be input. Therefore, instead of using special characters with frequent frequency using a letter board arrangement or character code table as in a conventional keyboard, a combination of a character input key (11), a subspace key (1) and a special symbol key (2) is used. Special characters can be used conveniently. In addition, since the long space bar on the conventional keyboard body can be divided into sub keys and the vertical or special characters can be arranged to be used as a special character key in the conventional special symbol key, the keyboard is convenient and easy to configure.

As described above, the present invention can be easily used in the 2 bee style and 3 bee style Hangul mode, it is suitable for both high-speed typing such as general typing and shorthand, and can effectively use the space bar on the keyboard, By specially preparing a special character key has a useful effect that can be convenient for users.
