ABSTRACT:
A flexible printed circuit board supporting structure for mounting a flexible printed circuit board in a restricted space without using an exclusive member to support the flexible printed circuit board. A lens barrel includes a fixed lens barrel integrally secured to a camera body and a movable lens barrel positioned in the fixed lens barrel and movable in the direction of the optical axis. An electrically driven device such as a shutter is mounted to the movable lens barrel and a controller for the electrically driven device is mounted to the camera body. A flexible printed circuit board electrically connects the controller to the electrically driven device. The flexible printed circuit board is connected to the electrically driven device and is extracted toward the rear of a camera in the movable lens barrel. The flexible printed circuit board also extends toward the front of the camera in a space formed between the fixed lens barrel and the movable lens a barrel and is drawn out of the fixed lens barrel from the front portion thereof. The flexible printed circuit board is supported in a space formed by the outer periphery of a light intercepting member which is disposed between the fixed lens barrel and the movable lens barrel, and the inner peripheral portion of the fixed lens barrel.
