Abstract
Disclosed is a hinge module for a three-step open type portable terminal and a portable terminal having the same, in which a body of the portable terminal is divided into three body sections and semi-automatically slides. The portable terminal includes a hinge module, which couples the upper body to the intermediate body in such a manner that the upper body is movable in a transverse direction relative to the intermediate body and couples the lower body to the intermediate body in such a manner that the lower body is movable in a longitudinal direction relative to the intermediate body.
