Abstract
A waterproof camera having an opening which is formed in a stationary barrel of a camera body and in which a photographing lens barrel is movable in an optical axis direction. A movable waterproofing cover is movable in an optical axis direction to a waterproof position and a non-waterproof position and which is provided on its front end with a transparent waterproof member. A securing device secures the waterproofing cover to the stationary barrel when the waterproofing cover is positioned at the waterproof position, and an annular seal member establishes a watertight connection between the opening and the waterproofing cover when the waterproofing cover is secured to the stationary barrel at the waterproof position.
Claims13
A camera comprising:
- an opening which is formed in a stationary barrel of a camera body and in which a photographing lens barrel is movable in said opening in an optical axis direction;
- a waterproofing cover which is movable in the optical axis direction independently from said photographing lens barrel to a projected waterproof position and a non-waterproof position, said cover being provided on its front end with a transparent waterproof member, said waterproofing cover being secured to and movable together with the photographing lens barrel when the waterproofing cover is positioned at the non-waterproof position;
- thread means for securing the waterproofing cover to the stationary barrel when the waterproofing cover is positioned at the waterproof position;
- and
- a sealing means which establishes a watertight connection between the opening and the waterproofing cover when the waterproofing cover is secured by the securing means at the waterproof position.
A camera comprising:
- a stationary barrel having an opening;
- a photographing lens barrel which is movable in the optical axis direction through the opening of the stationary barrel;
- and
- a movable barrel which is provided on its front end with a transparent member and which is movable independently from said photographing lens barrel in the optical axis direction in a space between the outer periphery of the photographing lens barrel and the opening of the stationary barrel to a projected waterproof position and a non-waterproof position, said movable barrel being secured to and movable together with the photographing lens barrel when the movable barrel is positioned at the non-waterproof position, said movable barrel being secured to said photographing lens barrel by thread means.
A camera comprising:
- an opening which is formed in a stationary barrel of a camera body;
- a waterproofing cover which is movable in an optical axis direction through the opening to a projected position, said cover being provided on its front end with a transparent waterproof member
- a securing means for securing the waterproofing cover to the stationary barrel when the waterproofing cover is positioned at the projected position, said securing means comprising a male thread portion which is provided on a rear end of an outer periphery of the waterproofing cover in the optical axis direction, and a female thread portion which is provided on an inner periphery of the stationary barrel in the vicinity of the opening, said male and female thread portions being separable from each other when said waterproofing cover is not at the projected position and being in engagement with each other to secure said waterproofing cover at the projected position;
- and
- a sealing means which establishes a watertight connection between the opening and the waterproofing cover when the waterproofing cover is secured by the securing means at the projected position.
