ABSTRACT:
A flexible printed circuit board housing structure for a lens barrel of a camera as applied to a camera that includes a control unit, a film chamber, a stationary barrel, a movable barrel, and a flexible printed circuit board. The movable barrel is supported on the stationary barrel in a manner enabling movement in the optical axis direction. The movable barrel houses a shutter unit and the flexible printed circuit board is connected between the shutter unit and the control unit. The flexible printed circuit board housing structure includes an FPC housing space, an FPC relief hole, and a spring. The FPC housing space is formed between the stationary barrel and a substantially cylindrical outer face of the film chamber and is provided with the spring. The FPC relief hole is formed in the stationary barrel and passes through the stationary barrel to the FPC housing space. The spring applies an urging force to urge the flexible printed circuit board into the FPC housing space through the FPC relief hole.
