ABSTRACT:
A camera body houses a rotatable pinion disposed in engagement with a fixed rack for translation along the rack as the pinion is rotated. A manipulatable portion of the pinion exteriorly projects through a slot in the camera body, enabling the pinion to be manually rotated. A slide member rotatably supports the pinion and is supported within the camera body for translation by the rotated pinion in adjacent overlapping relation to the slot. In this way, the slide member maintains the slot substantially closed to dirt or other foreign matter during the various stages of rotation of the pinion. A control element, adjustably movable for focusing or exposure control, is operatively coupled to the slide member for movement by the slide member in response to manual rotation of the pinion. A visual indicator on the slide member is viewable through a window in the camera body for indicating the proper setting of the control element.
