A portable phone incorporating an opening and closing mechanism comprises a main body, a sub-body, a hinge unit, and distribution cables. The main body and the sub-body respectively include electric circuits. The hinge unit includes a shaft disposed at one end of the sub-body, a cam having a center axis coupled to the shaft and used for regulating opening and closing angles of the sub-body, and a pair of leaf springs for maintaining turning angles of the cam. The distribution cables are connected to the electric circuits, and have their center portions wound around the shaft of the hinge unit. The distribution cables are stretched or compressed when the sub-body is opened or closed.
