As described above, a representative character extracted based on the common feature (common character portion) of the overall shape of each character having the entire Arabic character corresponding to the input target character and the representative character serving as the base of the character, Characters can be divided into subscripts to be completed, and the subscripts for forming a specific Arabic character are input after the representative characters are pre-input, thereby achieving consistency of the input method.

In addition, since a plurality of characters are assigned to one input key, the assigned characters are sequentially changed according to the number of times the corresponding input key is operated, and the characters are sequentially displayed, The representative characters and suffixes are independently assigned to each input key 112 and 114, so that a representative character or subscript can be input by one input key operation, thereby minimizing the number of operations for character input Thus, the time for inputting characters can be greatly shortened.

In addition, representative characters or subscripts are individually arranged in each of the input keys 112 and 114 partitioned into the independent areas in the keypad 110, so that the representative characters and subscripts arranged in the input keys 112 and 114 are intuitively recognized The positions of the input keys 112 and 114 in which representative characters or subscripts to be input by the user are arranged can be easily identified and selected, thereby further shortening the character input time.

If the display 130 is a touch screen, the keypad 110 is displayed on the screen as a part of the touch screen, and the keypad 110 is provided with a keypad 110 for selecting one of Arabic, Farsi, and Urdu languages. A language switching key 115 is arranged.

The control unit 120 may also be configured such that representative characters and suffixes of the Arabic characters used in the specific Arabic language selected by the language change key 115 correspond to the representative character key 112 and subscript area 113 of the representative character area 111. [ The suffix key 114 of the second embodiment.

In FIG. 5, representative characters derived from Arabic characters used in Arabic and Arabic characters of Arabic are shown. In FIG. 6, representative characters derived from Arabic Arabic characters are arranged in a representative character area 111 7 and 8 show the representative characters of the Parsi Arabic characters, and the representative characters of the Urdu Arabic characters are shown in FIGS. 9 and 10, respectively. In each Arabic language thus derived The data for each representative character and suffix may be stored in the memory 121 and read out if necessary and displayed on each representative character area 111 and subscript area 113. [

Referring to the drawings, Arabic characters used in Arabic languages of Arabic, Farsi and Urdu are Arabic, some of which use the same Arabic characters and some of which use unique Arabic characters used only in the Arabic language, Representative characters derived from Arabic characters can also be different.

[ 12, only the input key 114 to which the selected subscript is assigned is controlled to be arranged in the subscript area 113. In addition to the input key 114 to which unselected subscripts are assigned, It is preferable to control so that the input key 114 of the subscripts selected at the same arrangement position as that of the input key 114 is displayed.

Since the input key 114 in which the selected subscripts are arranged is displayed so as to be distinguished from the other input keys or only the input key 114 of the subscripted subscript is displayed, it is possible to more easily and quickly identify and select the subscript to be input by the user The character input time can be further shortened. Furthermore, by arranging the subscript key 114 at a fixed position, it is easy to know the arrangement of the keypad with subscripts, so that predictive character input is possible, thereby further shortening the character input time. In addition, when only the input key 114 of the selected subscript is displayed as shown in FIG. 13, the input key 114 of the subscript selected in the subscript area 113 is enlarged and displayed, so that the visibility of the input target key Can be further increased.

Meanwhile, the character input apparatus 100 for the Arabic language according to the preferred embodiment of the present invention allocates and arranges one representative character to each representative character key 112 included in the representative character area 111 , Two representative characters may be allocated and arranged for each representative character key 112 as shown in FIG. Also, the keypad 110 outputs a character input signal for inputting a representative character at a position selected by the user based on a position where the two representative characters arranged in the representative character key 112 are arranged.

More specifically, when the keypad 110 is displayed as a part of the touch screen, as shown in FIG. 15, each representative character key 112 displays the entire touch area on the basis of a position where two representative characters are arranged, (T1, T2). In the figure, two representative characters are arranged to be located on the left side and the right side, but the present invention is not limited to this, and two regions may be distinguished from each other in the upper side and the lower side or the oblique direction.
