Abstract:
1. A mounting structure of a flexible printed circuit board, comprising: a flexible printed circuit board folded back and routed between slide facing surfaces of a first housing and a second housing both being mechanically coupled to each other in a manner being freely slidable to electrically connect said first and second housings wherein a height of a sidewall surface making up at least one of said first and second housings changes in a slanted and inclined manner at a constant angle of inclination along a freely slidable direction; and a concave space portion on a slide facing surface making up said at least one of said first and second housings to accommodate flexible changes in folding-back curvature and folding-back position of said flexible printed circuit board caused by sliding motion between said first and second housings, wherein said flexible printed circuit board is always folded back toward an opposite direction to a direction of sliding open motion, irrespective of sliding state between said first and second housings, and wherein a depth of said concave space portion increases at a constant increasing rate with increasing height of said sidewall surface, whereas a depth of said concave space portion decreases at a constant decreasing rate with decreasing height of said sidewall surface.
