ABSTRACT:
In a camera, a shutter unit is mounted to a movable lens system for movement therewith along an optical axis. An annular member is arranged between the shutter unit and a camera body, for moving the shutter unit. A control signal from a control unit within the camera body is supplied to the shutter unit through a flexible element. The flexible element is turned back plurality of times within a space defined by the annular member so as to have at least two first and second turned-back portions spaced away from each other along the optical axis, whereby the flexible element has at least three sections including a first section extending between the shutter unit and the first turned-back portion, a second section extending between the first and second turned-back portions, and a third section extending between the second turned-back portion and the control unit. These sections overlap with each other in a direction normal to the optical axis.
