Key data input device and mobile communication terminal using the same
First Claim
1. A one-keyed data input device for a mobile communication terminal, comprising:
- a recess portion formed on a top surface of a main body of a terminal;
a center key positioned in the recess portion, said center key being arranged to be movable in an uppermost or lowermost direction or in a leftmost or rightmost direction from the center of the recess portion and movable in a radial direction from the center; and
a data input assembly having a signal generation guide assembly for generating, after moving the signal generation guide assembly to a desired location and depressing the the center key, an electrical signal for selected data, said signal generation guide assembly being moveable together with the center key coupled thereto, a vertically moving conductive material disposed below and in contact with the signal generation guide assembly, a first elastic guide body disposed below the vertically moving conductive material for providing the vertically moving conductive material with a force to make contact with the signal generation guide assembly, a base supporting the first elastic body and the signal generation guide assembly, the base for transferring an electrical signal to a main printed circuit board,wherein the electrical signal inputs different data depending upon the desired location of the center key.

Abstract
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.
