First, the CPU 400 receives a character mode selection signal selected by the driver from the rotary encoder character input means 100 (S100).

Then, the CPU 400 determines whether or not the character mode selection signal received from the rotary encoder character input means 100 is a Korean input mode (S200).

At this time, if the character mode selection signal is the Hangul input mode in step 200, the CPU 400 inputs the rotation operation of the driver's rotary encoder 120 and the same letter of the third function button 113. Receiving a text signal selected by a continuous operation such as consonant / vowel switching, cursor movement to the next letter, and pushing the push button 130 after confirmation, and simultaneously allowing the driver to visually check the text signal. The display is displayed on the document editing unit 820 in the LCD unit 800 (S300).

Here, the detailed operation of the 300th step S300 will be described in more detail with reference to FIG. 7 as follows.

First, the CPU 400 receives a switching function signal of a Korean consonant and a vowel by selecting a second function button 112 by a driver, and simultaneously inputs all consonants (basic consonant + pair) to the corresponding initial consonants. Consonant) is displayed on the character selection box 810 in the LCD unit 800 (S301).

Here, in all the consonants, the basic consonants mean (b, b, c, d, k, k, k, k, k, k, k, k, k, k), and consonants (k, k, ㅃ, ㅆ, ㅉ) means.

Subsequently, the CPU 400 is located with a consonant input to the initial consonant according to the rotation operation of the rotary encoder 120 by a driver, and in the state where the initial consonant is located, the CPU 400 selects the pressing of the third function button 113. By receiving the first consonant signal by the first consonant and displays the first consonant on the document editing unit 820 in the LCD (800) (S302).

Then, the CPU 400 displays all the vowels (basic vowel + section) of the consonant display of the character selection column 810 in the LCD unit 800 according to the pressing selection signal of the third function button 113 by the driver. (S303).

Here, in all the vowels, the basic vowel means (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ), and the parent sound is (ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ) means.

The CPU 400 inputs a neutral vowel signal by pressing and selecting the third function button 113 in a state where a vowel for neutral input is located according to a rotation operation of the rotary encoder 120 by a driver. Upon receipt, the neutral vowel is displayed on the document editing unit 820 in the LCD unit 800 (S304).

Subsequently, the CPU 400 moves the cursor to the next letter after confirming input of a character according to the pressing selection signal of the third function button 113 by the driver, and then rotates the rotary encoder 120 by the driver. According to the new English alphabet is located, the new English alphabet signal is received by pressing the selection of the third function button 113 in the state that the English alphabet is located and at the same time the new English alphabet in the LCD unit 800 The document editing unit 820 is displayed (S603), and the above-described operation is repeatedly performed until the character input by the driver is completed.

On the other hand, if the character mode selection signal is not the English input mode in step 500 (S500), the CPU 400 determines that the special key input mode (S700).

Thereafter, the CPU 400 inputs a special key character signal selected by a continuous operation such as a rotation operation of the driver's rotary encoder 120 and pressing of the third function button and pressing of the push button 130. Upon reception, the special key text signal is displayed on the document editing unit 820 in the LCD unit 800 so that the driver can visually check the signal signal (S800).

The display is displayed on the character selection box 810 in the LCD unit 800 (S801).

Then, the CPU 400 is a special character or number of the special key is located in accordance with the rotation operation of the rotary encoder 120 by the driver, the third function in the state where the special character or number of the special key is located By pressing the button 113, a special character or numeric signal of the special key is received and the special character or number of the special key is displayed on the document editing unit 820 in the LCD unit 800 (S802).

Subsequently, the CPU 400 moves the cursor to the next letter after confirming input of a character according to the pressing selection signal of the third function button 113 by the driver, and then rotates the rotary encoder 120 by the driver. According to the special letters or numbers of the new special key, the special letters or numbers of the new special key are input by pressing the third function button 113 while the special letters or numbers of the special key are located. Upon receipt, the special character or number of the new special key is displayed on the document editing unit 820 in the LCD unit 800 (S803).

Thereafter, the CPU 400 receives a text input completion signal generated by the driver's one-time press selection from the push button 130 and terminates the text input corresponding thereto (S400).

On the other hand, Figure 10 is a schematic diagram illustrating a character input method of OttoPC using a rotary encoder according to an embodiment of the present invention, a process example of the character input of "Ssamji A" shown in Figure 10 Same as

First, when entering the first character, select the Hangul / English / Special Key mode through the first function button 111 (▼). (In this case, it is the default for Korean and not pressed for Korean input.)

Subsequently, the initial consonant (ㅆ) is positioned at the selection of the character selection box 810 through the rotation of the rotary encoder 120, and then the third function button 113 (▶) is pressed to press the first consonant (ㅆ). ) Is displayed on the document editing unit 820.

In this case, the text selection box 810 automatically enters the consonant consonant in the document consonant mode from the consonant consonant mode to the neutral vowel mode.

Then, the neutral vowel (ㅏ) is positioned in the selection of the letter selection box 810 through the rotation of the rotary encoder 120, and the third function button 113 (▶) is pressed to press the neutral vowel (ㅏ). ) Is displayed on the document editing unit 820.

In this case, the character selection column 810 automatically proceeds from the neutral vowel to the final consonant mode as the neutral vowel is inputted to the document editing unit 820. Here, a blank area is first positioned in the letter selection column 810 when the neutral vowel is switched to the final consonant mode.

Subsequently, after the rotary encoder 120 rotates the final consonant (ㅁ) to the selection of the character selection column 810, the third function button 113 (▶) is pressed to press the final consonant (ㅁ). Is displayed on the document editing unit 820.

Subsequently, the letter corresponding to the consonant consonant is displayed again on the letter selector 810, and after the initial consonant is placed on the selection of the letter selector 810 through the rotation of the rotary encoder 120. Pressing the third function button 113 (▶) to display the new consonant consonant (ㅈ) on the document editing unit (820).

Subsequently, after the rotary encoder 120 is rotated, the new neutral vowel ㅣ is positioned at the selection of the letter selection box 810 and the third function button 113 (▶) is pressed to select the new neutral vowel ( L) is displayed on the document editing unit 820.

In this case, since the input letter "Z" does not have a final consonant, when the third function button 113 (▶) is pressed in the blank area which is first positioned at the time of switching to the final consonant mode in the letter selection column 810, the next letter The cursor is skipped to.

Thereafter, the driver presses the first function button 111 (▼) to input the English letter “A” to switch from the Korean mode to the English mode. In this case, in the case of the English letter, if the first lowercase letter is set to be shown first, the second function button 112 (▲) is pressed to convert from the lowercase letter to uppercase.

Subsequently, after the rotary encoder 120 is rotated, the desired letter A is placed at the selected position of the letter selection box 810, and then the third function button 113 (▶) is pressed to select the corresponding letter. Enter it.

Then, when the push button 130 (●) is pressed, input of characters displayed on the document editing unit 820 is completed.

In this case, the push button 130 is used only when the input is completed or the line is changed, which has the advantage that the input of a fast character is possible when inputting with both hands.
