Abstract

A swing and folder type mobile communication terminal is provided to protect an FPCB(Flexible Printed Circuit Board) by covering the FPCB, thereby preventing the FPCB from being disconnected when a main unit and a folder unit perform swing rotations or are folded/unfolded. An FPCB electrically connects a main unit(110) with a folder unit(120). The first swing hinge(140) swings/rotates the folder unit(120) on the main unit(110) in connection with the folder unit(120), and is equipped with the first guide hole(143) through which the FPCB passes on one side. A folding hinge(150) has a conduit line for guiding as protecting the FPCB by forming a mobile path of the FPCB in connection with the first guide hole(143), while one side of the hinge(150) is combined with the first swing hinge(140) while the other side is combined with the main unit(110) to fold/rotate the main unit(110) and the folder unit(120).
