Abstract: A portable, foldable data input device for use with a mobile communication terminal. The data input device includes a first housing having an edge defining a first slope; a second housing having an edge defining a second slope facing the first slope when the first and second housings are unfolded; and conical hinge means situated between the first and second housings, for coupling the first housing to the second housing. The conical hinge means comprises first and second side hinge arms facing each other, mounted on the first housing; and a center hinge arm coaxially interposed between the first and second side hinge arms, the center hinge arm being mounted on the second housing.
