Abstract
A key input apparatus includes a block unit to block a key recognition signal input through a signal input path from being provided to an end of a switch connected to a signal output path if the switch is in an ON state. Thus, if there multiple key inputs are entered simultaneously or sequentially, a correct key input can be more accurately recognized.
