ELECTROSTATIC SURGE PREVENTIVE STRUCTURE

PROBLEM TO BE SOLVED: To provide an electrostatic surge preventive structure capable of improving durability to an electrostatic surge, reducing a cost and man-hour, and saving a space.SOLUTION: At a position corresponding to a clearance 41 between a front case 22 formed on a display device 12 and a touch panel assembly 21, a flexible printed circuit board 31 connected to a control printed circuit board stored in the front case 22. The flexible printed circuit board 31 has conductor portions 43 and 44 of two layers. The surfaces of the conductive portions 43 and 44 are covered by insulation coats 46 and 47, and an exposing portion 44A (or a coating portion 51 by plating as the exposing portion) where the insulation coat 47 is peeled and the conductor portion 44 is exposed to the outside is formed at a part opposite to the clearance 41, and the conductor portion 44 having the exposing portion 44A (or the coating portion 51) is grounded.SELECTED DRAWING: Figure 4 【課題】静電サージに対する耐性の向上、コスト及び工数の削減、省スペース化を可能とする静電サージ防止構造を提供する。【解決手段】表示装置１２に出来た前ケース２２とタッチパネル組立体２１との間隙４１に対応する位置に、前ケース２２に収納される制御プリント基板に接続されたフレキシブルプリント基板３１が設けられ、フレキシブルプリント基板３１は、２層の導体部４３，４４を有し、これらの導体部４３，４４の表面が絶縁被覆４６，４７で覆われ、間隙４１に対向する部分に絶縁被覆４７が剥がされて導体部４４が外部に露出する露出部４４Ａ（又は露出部としてのめっきによる被覆部５１）が形成され、露出部４４Ａ（又は被覆部５１）を有する導体部４４が接地される。【選択図】図４
