<p>A portable phone incorporating an opening and closing mechanism comprises a main body (1), a sub-body (2), a hinge unit (3), and distribution cables (7, 8). The main body (1) and the sub-body (2) respectively include electric circuits (9, 10). The hinge unit (5) includes a shaft (5) disposed at one end of the sub-body (2), a cam (4) having a center axis coupled to the shaft (5) and used for regulating the opening and closing angles of the sub-body (2), and a pair of leaf springs (3) for maintaining turning angles of the cam (4). The distribution cables (7, 8) are connected to the electric circuits (9, 10), and have their intermediate portions wound around the shaft (5) of the hinge unit (6). The distribution cables (7, 8) are stretched or compressed when the sub-body (2) is opened or closed. <IMAGE></p> |
