Abstract
PURPOSE: To achieve the simplification of construction and reduction of cost by providing the rotation-control mechanisms which revolve and control various adjusting rings rotatably mounted to the lens barrel with the single driving output shaft.
CONSTITUTION: The iris-adjusting ring 2, zoom-adjusting ring 3 and focus-adjusting ring 4 mounted rotatably to a lens-barrel 1 are revolved and controlled by a single driving output shaft 8 parallel to the optical axis of the lens barrel 1 and rotation control mechanisms 18, 19 and 20 for various adjusting rings. For example, to manually operate the iris-adjusting ring 2, the current supply to a solenoid 25 is stopped to release the suction action of magnets 22, 23 and detach idlers 31, 32 from the adjusting ring. Next, to expand or reduce thw exposure of iris current is supplied to the solenoid 25 that the idler 31 or 32 makes contact to the adjusting ring 2. The respective rotation-control mechanisms for zoom and focus are operated in a similar manner. In this way, the mechanisms may be simplified.
