Referring to FIG. 2, the wireless communication unit 440 converts a transmission signal of the communication terminal into a wireless signal and transmits the signal, and converts a received wireless signal into a reception signal. The wireless communication unit 440 may be connected to a public wireless communication network or may be connected to a local area wireless communication network.

The memory 420 may be composed of a program memory and a data memory. The program memory stores programs for processing a call processing of a portable terminal and programs for processing key data generated in a joystick type character input unit according to an embodiment of the present invention. The data memory temporarily stores data generated while executing the programs. The memory 420 includes font data for characters in a character input mode set by a user.

The controller 400 controls the overall operation of the portable terminal. In addition, the control unit 400 includes a modem for modulating and demodulating a signal, a codec for decoding / decoding, and encodes and modulates a transmission signal, and performs a function of demodulating and decoding a received signal. The control unit 400 may be an MSM chip. The controller 400 may independently configure a data processor that separates the modem and the codec, and the data processor may be positioned between the wireless communication unit 440 and the controller 400.

The key input unit 410 includes keys for inputting numeric and character information and function keys for setting various functions. The display unit 430 may display menus according to the operation of the mobile terminal under the control of the controller 400, and display text input data according to an embodiment of the present invention. The handset 450 processes an audio signal generated in a communication mode under the control of the controller 400 in a communication mode.

Here, the key input unit 410 includes a character input unit 300 according to an embodiment of the present invention. That is, the key input unit 410 includes at least one character input unit 300 including a conversion key 350 for setting a character input mode and at least a joystick switch. The character input unit 300 is divided into at least two directions as described above, each direction includes at least one character unit, and each character unit is configured to match at least one character data. In the embodiment of the present invention, it is assumed that the character input unit 300 is divided into four directions as described above, and these four directions are left and right and up and down. In addition, each of the four directions of the character input unit 300 includes two first and second character units 310 and 340, and a basic consonant and a hard sound are disposed in the first character unit 310, and the first character unit in the second character unit 340. Arrange the sound of the character unit 340. In addition, a stick protrusion 330 is mounted at the center of the character input unit 300. Here, the stick protrusion 330 performs a function for selecting the first or second character portion 310 or 340, and may select the direction of the character input portions in the same manner as a joystick. Therefore, when a user inputs a character through the character input unit 300, the user can first select the first character unit 310 or the second character unit 320 by turning on / off (pressing / not pressing) the stick protrusion 330. By sliding the stick protrusion 330, the direction and the number of times of the character input unit 300 may be set. Therefore, as shown in FIG. 1, it is assumed that “a” and “ㄲ” are disposed in the first character unit 310 in the left direction of the character input unit 300 and “ㅋ” is disposed in the second character unit 340. In this case, in the case of inputting “a”, the stick protrusion 330 may be slid to the left in a state in which the stick protrusion 330 is turned off (not pressed). In addition, in the case of inputting “ㅋ”, the stick protrusion 330 may be slid leftward while the stick protrusion 330 is turned on.

The key input unit 410 may configure a plurality of character input units 300 having the above configuration. In the embodiment of the present invention, it is assumed that four character input units are provided as described above. Here, the character input units 300 may input Korean and English characters, and the character input unit 300 for Korean input uses two character input units for inputting consonant characters and one character input unit for inputting vowel characters. Assume

To this end, the control unit 400 has a function of processing the character input data of the key input unit 410. That is, when the signal S1 of the conversion key 350 is generated, the controller 400 determines the character input mode by analyzing the number of occurrences of the signal S1 (the number of presses of the conversion key 350). The character input mode may be a Korean, English and / or numeric input mode. In addition, when a character is input from the key fitting unit 410, the controller 400 generates character data matching the corresponding key input unit 410. The control unit 400 includes a table for the direction of each key input unit 410, the character units in each direction, and the character data that may be generated in each character unit. The table for the character data may include the character data according to the sliding duration of the stick portion 320 in a state in which the character data and the stick protrusion 330 are turned on (pressed state) in the sliding duration of the stick portion 320.

When an input is generated from the character input unit, the controller 400 checks which character input unit is used, and then checks whether the pressing unit and the sliding direction and sliding duration generated by the stick unit protrusion 330 correspond to the corresponding character data corresponding to the corresponding character input unit. Create

At this time, when an input occurs in the key input unit 410, the control unit 400 detects the signal S2 (whether pressed) of the stick protrusion 330 and sets the character unit (first or second character unit). The controller 400 determines the direction and the text data with reference to the signal S3 of the stick protrusion 330. In this case, S3 includes a direction in which the user slides and a sliding duration. Accordingly, the controller 400 determines the character input mode according to the signal S1 of the conversion key 350, selects a character part according to whether the stick part protrusion 330 is pressed, and selects a direction according to the sliding and sliding duration of the stick part 320. Detect character data of character part of. When the stick protrusion 330 is positioned at the neutral position, the controller 400 displays the input character on the display unit 430.

The user may input characters while repeating the above operation, and the controller 400 accesses font data corresponding to the input characters from the memory 420 and displays them on the display unit 430. In this case, when the Hangul input mode is set by the conversion key 350, the controller 400 generates Hangul characters by combining the input Hangul characters (consonants and vowels), and accesses the generated Hangul characters from the font memory. To display.

3 is a flowchart illustrating a character processing procedure according to an embodiment of the present invention. Here, the processing of the character data generated by one character input unit 300 will be described.

Referring to FIG. 3, when the input of the conversion key 350 is detected, the controller 400 sets a character input mode according to the input of the conversion key 350 in step 511. Herein, the character input mode may be a Korean or English character input mode. In the embodiment of the present invention, it is assumed that the character input mode is a Korean input mode.

When the input of the stick protrusion 330 of the character input unit 300 is generated while the character input mode is set as described above, the control unit 400 determines whether the stick unit protrusion 330 of the corresponding character input unit 300 is pressed in step 513. In step 515, the contact of the stick protrusion 330 is checked to determine the direction on the character input unit 330. In step 517, the character duration is determined by checking the sliding duration of the stick 320. That is, when an input is generated by the character input unit 300, the controller 300 determines whether the stick unit protrusion 330 of the character input unit 300 is pressed to determine the first character unit or the second character unit, and the sliding direction and The sliding duration is examined to determine mapped character data of the first character portion or the second character portion in the corresponding direction. If the stick protrusion 330 is located in the neutral position, the controller 300 accesses the font of the checked character data in the memory 420 in step 521 and displays it on the display unit 519.

Character input through the character input unit 300 is repeated, and the control unit 400 displays the character data generated by combining the consonants and vowels generated as described above while repeating steps 513 to 519 on the display unit 420. If a termination command is generated in the state of processing the input text data as described above, the controller 400 detects it in step 521 and terminates the text input processing procedure.

The present invention has an effect of maximizing ease of use and minimizing character input time in a portable terminal by using a character input unit forming a joystick type stick unit provided in the character input panel.

In addition, the present invention by using the character input unit by the parallel operation of the stick portion by the character is repeatedly displayed on the display sequentially and the pressing operation is added to another predetermined character is displayed repeatedly repeatedly by using a small number of character input unit There is an effect that can reduce the size of the portable terminal.

In addition, the consonant uses two character inputs and the vowel can use one character input, so the left hand can be equipped with the opposite. However, the consonant part is the left hand and the vowel part is the right hand. By using a joystick type character input unit, the character can be input easily and quickly.

In addition, the present invention has the effect that it is possible to simplify the design of the character input panel of the portable terminal by using a function key, such as an arrow key for direction movement by the function input unit.
