Abstract

In a water-sealed camera arranged to be watertight except a portion at which a movable lens barrel is located, the water-sealed camera is further arranged to detachably mount a waterproofing lens cover for watertightly covering the movable lens barrel. Thus, the camera can be arranged to be completely watertight irrespective of the presence of the movable lens barrel.

Claims

1. A water-sealed camera including a predetermined portion arranged to be non-watertight, a lens barrel movable relative to an external cylinder fixed on said water sealed camera, said lens barrel located at said non-water tight predetermined portion, and a cover member for watertightly covering said predetermined portion.

2. The water-sealed camera according to claim 1, wherein said cover member comprises a waterproof lens cover, and further including means for detachably mounting said waterproof lens cover on said water-sealed camera.

3. The water-sealed camera according to claim 2, wherein said waterproof lens cover comprises a cylindrical portion and a transparent plate secured to a side of said cylindrical portion.

4. The water-sealed camera according to claim 2, wherein said means for detachably mounting said waterproofing lens cover comprises a screw portion formed on an inner surface of said waterproofing lens cover and another screw portion formed on said external cylinder.

5. The water-sealed camera according to claim 2, wherein said waterproof lens cover is arranged to be tapered toward the front side of said water-sealed camera when said waterproof lens cover is mounted on said water-sealed camera.

6. A watertight mechanism adapted to be positioned on a device, said device being arranged to be watertight except for a predetermined portion at which a movable member is located, said movable member being movable relative to an external surface of said device, said watertight mechanism comprising a cover member arranged to be detachably mounted on said device for watertightly covering said predetermined portion and said movable member.

7. A waterproof cover member for a camera having a generally cylindrical housing movable relative to a camera body, said cover member comprising:

a generally cylindrical member adapted to fit over the relatively movable housing; and

an annular sealing means at one end of said cylindrical member adapted to mate with a fixed portion of the camera body adjacent to said generally cylindrical member.

8. The waterproof cover member according to claim 7, further comprising a transparent plate secured adjacent the other end of said generally cylindrical member.
