发明名称 WATERPROOF CAMERA
摘要 PROBLEM TO BE SOLVED: To inexpensively provide a waterproof camera excellent in versatility and capable of anti-fogging it with a simple structure. SOLUTION: A waterproof film unit 2 with a lens is composed of a film unit 3 with a lens and a waterproof case 4 housing the unit 3. The front surface of the case 4 is provided with exposing parts for exposing a photographing lens and a finder. Then, thin parts 32a and 32b being thinner than the exposing part are formed at both side surfaces of the case 4. Because of that, when the unit 2 is carried underwater and the peripheral temperature of the case 4 is suddenly lowered, the temperature of the inside walls of the thin parts 32a and 32b are lowered earlier than that of the other part. Thus, moisture in air in the case 4 is concentrated at the thin parts 32a and 32b and it becomes dewdrops there. As the result, the moisture is reduced and the dewdrops are hard to be formed at the exposing part.
