Abstract
PURPOSE:To enable to obtain a folding type electronic devices with good durability, by using hinge member incorporating lead wire in the inside and formed in the form of coil spring. CONSTITUTION:An insulating plate 17 is located under a printed circuit board 16 of frame bodies 2, 3 left and right, and a number of contacts 18 made of conductive rubber are unifiedly provided at the upper side, and a number of keys 8 are fitted to the contacts 18. A number of through-holes 13 are formed at projections 2a, 3a of the frames 2, 3. Lead wires are incorporated in the hinge member 14, the outside is coated with synthetic resin and formed in the form of coil spring and sequentially passed through the through-holes 13. The both ends of the hinge 14 are electrically connected to the printed circuit board 16.
