焦点調節装置。 In a camera in which the focal length of the photographic lens is made variable by moving a shutter unit incorporating the photographic lens in the optical axis direction with respect to the camera body, there is provided a member that moves to position the photographic lens at the in-focus position, and a member that moves to position the photographic lens at a focus position. A first scanning member that interlocks with the member is disposed in the shutter unit, and a second scanning member that runs while supporting one of a pair of optical distance detection elements consisting of a light emitting element and a light receiving element is disposed in the camera body. An automatic focusing device for a camera, characterized in that the two scanning members are coupled via a rotation transmission member disposed parallel to the optical axis of the camera.
