Abstract

PURPOSE: To reduce the diameter of waterproof packing and improve the operating characteristic of the camera by providing the driving shaft which performs focus adjustment and aperture adjustment through the lens barrel and letting the outside circumferential face of the lens barrel be a rotating sleeve.
CONSTITUTION: A focusing sleeve 11 which is manually operated from the outside is rotatably supported to the outside circumference of a lens barrel 3 and a crown gear 11a is formed on the circumferential face of its end. A gear 12 intermeshed with the crown gear is held fixed to one end of the driving shaft 13 penetrating through the lens barrel 3. When a sleever 11 is rotated, an objective lens 1 moves in the optical axis direction in cooperation to this and performs focus adjustment. A waterproof packing 15 such as rolling is inserted onto the driving shaft 13 and since the diameter of this packing may be made small, the driving force of the objective lens and the sleeve adjusting aperture blades may be reduced and the operating characteristic of the camera improved.
