In the mobile phone having a keypad having a keyboard arrangement as described above, the method of inputting letters, numbers, and symbols according to the present invention will be described in detail as follows.

First, a process of setting various input modes will be described.

When the mobile phone is turned on, the mobile phone is initially set to the Hangul mode, and in this mode, when the user presses the Korean / English key button 321 for a long time (1 second or more), the controller 220 displays the Hangul. Release the mode and set the phone to English mode. Likewise, when the English / Korean key button 321 is pressed for a long time (1 second or more) in the English mode state, the controller 220 releases the English mode and sets the mobile phone to the Korean mode.

In addition, when switching to the Hangul mode, the mobile phone is initially set to the consonant mode, and in this mode, when the user presses the child / mouse key button 321 for a short time (less than 1 second), the control unit 220 controls the consonant mode. Off and set the vowel mode. In the vowel mode set as described above, when the user presses the child / child key button 321 for a short time (less than 1 second), the controller 220 switches the mobile phone from the vowel mode to the consonant mode.

In addition, when switching to the English mode, the mobile phone is initially set to the uppercase input mode, in this mode, when the user presses the large / small key button 321 for a short time (less than 1 second), the control unit 220 capitalized Cancel input mode and set lowercase input mode. When the user presses the large / small key button 321 for a short time (less than 1 second) in the set lowercase input mode, the controller 220 switches the mobile phone from the lowercase input mode to the uppercase input mode.

In the state in which the text mode is set through this process, when the user presses the erase and symbol / numeric key buttons 322 for a long time (1 second or more), the controller 220 sets the mobile phone to the symbol mode. In the state set in the symbol mode, when the user selectively presses the key buttons 311 to 320, the controller 220 inputs the symbol assigned to the selected key button to the cellular phone.

Similarly, in this input mode, when the user presses the key button 324 for a long time (1 second or more), the controller 220 inputs the symbol '#' into the mobile phone, and the user presses the key button 324. When pressed for a short time (less than 1 second), the mobile phone is set to the right of the cursor.

Next, a method of inputting Hangul in the Hangul mode will be described.

When the user presses a key button to which a desired consonant is assigned in the consonant mode, the controller 220 inputs the consonant into the mobile phone. Here, since two consonants are assigned to each of the key buttons 311 to 319, in order to input consonants assigned to each key button, the user must press the key button once or twice. When the button is pressed once, the consonants displayed on the left are entered into the mobile phone. If the key button is pressed twice, the left consonants when pressed once are deleted and the consonants displayed on the right are entered into the mobile phone.

For example, in the consonant mode, when the user presses the key button 311 once, 'a' is input to the mobile phone, and if the user presses the key button 311 twice, the 'ㄲ' is input to the mobile phone.

If the user wants to input 'a' twice in a row, the user presses the key button 311 once to input 'a' and then press the key button 324 for a short time (less than 1 second) to move the cursor to the right. After moving, press key button 311 again to input 'ㄱ'.

However, in the consonant mode, if you want to continuously input consonants assigned to different key buttons, instead of pressing the key button 324 for moving the cursor, press the corresponding key button once and the desired consonants are continuously Enter it.

In order to input the vowel after inputting the consonant as described above, the user must press the child / parent key button 321 for a short time (less than 1 second) to set the mobile phone to the vowel mode.

In the state in which the cellular phone is set to the collection mode as described above, the user can input the collection to the cellular phone by pressing a key button to which the desired collection is assigned among the key buttons 311 to 320.

For example, when the user presses the key button 311 in the vowel mode, 'ㅏ' is input to the mobile phone.

Therefore, when the user inputs 'b' in the consonant mode to the cellular phone and presses the child / mo key button 321 to switch the cellular phone to the vowel mode and inputs 'ㅏ', the 'na' is input to the mobile phone.

In addition, only 10 vowels are allocated to the key buttons 311 to 320, and other Korean vowels such as “ㅔ, ㅖ, ㅐ, ㅒ, ㅢ, ㅚ, ㅘ, ㅟ, ㅝ” are assigned to the key buttons. It doesn't exist, but you enter it in the following way:

The composite vowel 'ㅔ' is inputted by pressing the key button 313 to which '된' is assigned and the key button 320 assigned to 'ㅣ' in succession, and the composite bar 'ㅖ' is the key button to which '버튼' is assigned 314 and 'ㅣ' are assigned by pressing the key button 320 in succession, the composite vowel 'ㅐ' is a key button 311 and 'ㅣ' is assigned a key button 320 ) And press continuously, and the composite vowel 'ㅒ' is inputted by pressing the key button 312 assigned with 'ㅑ' and the key button 320 assigned with 'ㅣ' in succession, and the composite vowel 'ㅢ' The key button 319 to which 'ㅡ' is assigned and the key button 320 to which 'ㅣ' are assigned are continuously pressed and input, and the composite vowel 'ㅚ' is assigned to the key button 315 and 'ㅣ to which' ㅗ 'is assigned. 'Continuely press the key button 320 assigned to enter, and the combination bar' ㅘ 'is input by pressing the key button 315 to which' ㅗ 'is assigned and the key button 311 to which' ㅏ 'is continuously assigned. And, the composite vowel '는' is the key button 317 to which 'TT' is assigned and ' 'Is inputted by continuously pressing the assigned key button 320, and the composite bar' ㅝ 'is input by pressing the key button 317 assigned to' TT 'and the key button 313 assigned to' ㅓ 'consecutively. do.

For example, in the vowel mode, when the user presses the key button 312 once to input 'ㅑ' and then presses the key button 320 to input 'ㅣ', 'ㅒ' is input to the mobile phone.
