PROBLEM TO BE SOLVED: To make it possible to protect the electrical connection part between an electric cord and a circuit board even if an external force is applied to the lead-out end part of the electric cord in the single constitution of an electric cord holding structure by a method wherein the cord is inserted in notch engaging parts and the cord is arranged in such a way that the cord is alternately distributed on the surface and rear of the circuit board. ;SOLUTION: A notch engaging part 8 consists of first and second notch engaging parts 81 and 82, an electric cord 5 soldered to the upper surface of a circuit board 3 is led out through the lower surface side 31 of the board 3, is inserted in the first engaging part 81, is distributed on the upper surface side 32 of the board 3 and thereafter, the code 5 is inserted in the second engaging part 82 and is again distributed on the lower surface side 31. The lead-out end part 5B of the cord 5 is led out from a lead-out hole part 7 formed in a lower case 2 toward the outside. In such a way, the cord 5 is arranged in such a way that the cord 5 is alternately routed on the surface and rear of the wiring board 3 by the engaging parts 81 and 82 and is held zigzag between a connection part 6 and the end part 5B.;COPYRIGHT: (C)1998,JPO
