Abstract

A portable communication device is disclosed. The portable communication device comprises a first housing extending in the longitudinal direction thereof, a second housing rotated about a first hinge axis perpendicular to the longitudinal direction of the first housing such that the angle between a bottom surface of the second housing and a corresponding top surface of the first housing varies, and a cylindrical hinge housing disposed at one end of the first housing while a portion of the cylindrical hinge housing protrudes outward from the first housing. The first hinge axis extends in the diametrical direction of the cylindrical hinge housing wherein the second housing is attached to the cylindrical hinge housing while the second housing is rotated about the first hinge axis. The cylindrical hinge housing has a second hinge axis extending in the axial direction of the cylindrical hinge housing so that the second housing can rotate about the second hinge axis. The second hinge axis is perpendicular to the first hinge axis.
