Waterproof camera

DETAILED DESCRIPTION In view of the above, a first object of the present invention is to provide a waterproof camera which is securely made watertight.
In order to attain the above-described object, a waterproof camera incorporating therein a camera mechanism assembly, a watertight outer box in which is housed the camera mechanism assembly and a waterproof interchangeable photographic lens detachably mounted on said outer box, comprises: a first space between the outer box and the interchangeable lens when the latter is mounted on the former; a first sealing member in the form of a ring fitted into said first space; the first sealing member preventing water outside of the outer box from intruding through said first space into the outer box; a second space defined between the outer box and the camera mechanism assembly; a second sealing member characterized by its ability of preventing the water intruded through said first sealing member from flowing into the interior of the camera mechanism assembly.
In the waterproof camera in accordance with the present invention with the above-mentioned construction, the first sealing member is fitted into the space defined by the interchangeable lens and the outer box when the interchangeable lens is mounted in the outer box.
In addition, the second sealing member is fitted into the space between the outer box and the camera mechanism assembly so that no water can intrude into the interior of the camera through the space between the outer box and the camera mechanism assembly.
A second object of the present invention is to automatically correct the offset of the optical axes between the camera mechanism assembly and the outer box.
In order to attain the above-described object, a waterproof camera incorporating therein a camera mechanism assembly, a watertight outer box in which is housed the camera mechanism assembly and a waterproof interchangeable photographic lens detachably mounted on the outer box comprises: an aperture formed through a wall of said outer box; and an elastic member disposed between an inner periphery of said aperture and said camera mechanism assembly and determining the position of said camera mechanism assembly relative to said aperture by imparting a uniform biasing force to said aperture
