Patent ID: 8804357

Claim:
A sliding-type portable electronic apparatus comprising a pair of casings which are slidably coupled to each other, a flexible lead which is derived from an electric component incorporated in one of the casings, further, is passed through an opening provided in the other casing and is connected to a circuit board incorporated in this other casing, and a waterproof sheet adapted to close the opening, wherein the flexible lead passed through the opening is extended along a front surface of the circuit board and, thereafter, is folded back from the front surface of the circuit board toward a rear surface thereof at a position on a side end surface of the circuit board, the flexible lead is connected, at its tip end portion, to the circuit board, on the rear surface of the circuit board, and the waterproof sheet is adhered, at its peripheral edge portions, to the flexible lead and to an inner surface of the other casing, at positions on a periphery of the opening, wherein the flexible lead passed through the opening extends in a lateral direction of the other casing along the front surface of the circuit board and, thereafter, is folded back from the front surface of the circuit board toward the rear surface thereof at a position on the side end surface of the circuit board.
