Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To avoid electrical shock caused by electric conduction through infiltrated seawater in the case of inadvertently dropping a film unit with a lens in the sea. SOLUTION: The housing body of this film unit with lens is constituted of a front cover 25 and a back cover 26. An avoidance projection 70 is formed on the cover 26 side at a part where the end face 51d of the aluminum case 51a of a main capacitor 51 approaches on a joint 24 between the covers 25 and 26. An avoidance recessed part 71 is formed on the cover 25 side. The projection 70 is formed as a circular arc having a larger diameter than the outside diameter of the case 51a so that the joint 24 may not approach to the end face 51d of the case 51a. Even when the seawater infiltrated because the film unit is dropped in the sea oozes out to the joint 24 between the covers 25 and 26 by a capillary phenomenon, the case 51a of the capacitor 51 does not contact with the seawater, so that the electic shock caused by the electric conduction through the seawater is avoided.
