Abstract
An FPC (flexible printed circuit) board arrangement structure for zoom lens barrels of a camera is provided. The FPC board connects a shutter block carried by each zoom lens and a controller carried by the camera. The FPC board has a first portion to be connected to the shutter block, a second portion to be connected to the controller, and a connecting portion connecting the first and second portions. The connecting portion includes at least one foldable portion and a deformable portion. The length of the deformable portion is substantially constant regardless of an extended amount of a zoom lens barrel. The foldable portion is folded when the flexible printed circuit board is implemented in one of the zoom lens barrels, and is unfolded when implemented in another zoom lens barrel.
