A character input device is disclosed. In one embodiment, the device includes i) a base including an input region, ii) two input units disposed in the input region, wherein each of the input units is disposed to perform direction inputs of more than two steps that selects any one of a plurality of direction instruction locations that are radially spaced apart from each other from each of reference locations within the input region in each of the direction instruction locations, iii) a direction input detecting unit detecting whether the direction inputs and a multiple input are performed and iv) a controller discriminating and inputting a first character that is redundantly allocated at the corresponding direction instruction location according to the direction instruction location in which the direction inputs are performed and whether the multiple input is performed. The character input device having the construction described above includes two sets of input units that input more than one phoneme at an operation, thereby doubling input quantity and simultaneously inputting a character quickly and accurately.
