1. An Arabic-Persian Alphabet input apparatus comprising:
- an Alphabet input unit having basic keys and one function key, wherein ten or more basic figures extracted from analyzed forms of Arabic Alphabet are allocated to the basic keys, the basic keys further comprising at least one variation key to indicate figures to be attached over or under Arabic characters to vary their pronunciations;
an Alphabet database unit for storing Arabic Alphabet information coded to correspond to basic key input signal combinations of the Alphabet input unit;
an Alphabet extracting unit for searching the Alphabet database unit to extract Arabic alphabets corresponding to combinations of initial basic key input signals inputted from the Alphabet input unit or basic key input signals following a function key signal;
a form database unit for storing information on combined forms of consecutive characters; and
a combined form determining unit for, when a character extracted by the Alphabet extracting unit is consecutive to a previously extracted character, searching the form database unit to determine a combined form of the two extracted characters.

Abstract
The present invention relates to an Arabic-Persian Alphabet input apparatus having ten or more basic keys on which basic figures extracted from analyzed forms of the Arabic Alphabet are inscribed, respectively. The basic key input signals are combined to easily and simply input the Arabic Alphabet to miniaturized and multi-functional electronic appliances such as cell phones whose buttons (keys) are limited in number. Further, the Arabic characters are inputted in the same manner as handwriting without having to particularly remember the Persian Alphabet.
