摘要

PROBLEM TO BE SOLVED: To prevent the internal pressure of an underwater camera case or the housing of a waterproof digital camera from rising by gas generated by a fuel cell.

SOLUTION: The digital camera 10 using the fuel cell 16 as a power source is housed in the underwater camera case 90 so as to perform underwater photography. The case 90 is provided with a pressure adjusting check valve 98. When the internal pressure of the case 90 rises to a specified value, the valve 98 is opened, so that the internal pressure of the case 90 drops.
