摘要： A mobile communication terminal with a one-keyed data input device is disclosed. The one-keyed data input device includes a recess portion formed on the top surface of a main body of the terminal and a center key positioned in the recess portion. The center key is arranged to be movable in the uppermost or lowermost direction or in the leftmost or rightmost direction from the center of the recess portion and movable in the radial direction from the center. The device includes a data input assembly having a signal generation guide assembly for generating an electrical signal for selected data, said signal generation guide assembly being movable together with the center key coupled thereto, a vertically moving conductive material disposed below and in contact with the signal generation guide assembly, against which the signal generation guide assembly may move, a first elastic body disposed below the vertically moving conductive material, for providing the vertically moving conductive material with a physical force to get contact with the signal generation guide assembly, and a base supporting the first elastic body and the signal generation guide assembly, for transferring generated electrical signal to a main printed circuit board.
