WATERPROOF FILM UNIT WITH LENS

PROBLEM TO BE SOLVED: To provide a film unit where an exposed film unit with a lens is easily taken out from a waterproof case. SOLUTION: When the film unit with the lens is taken out from the waterproof case 4, a jig 70 is pushed in a thin part 4a formed at the front face part 32 of the waterproof case 4, and the thin part 4a is broken, so that the jig 70 is inserted into the inside of the waterproof case 4. When the jig 70 is inserted into the inside of the waterproof case 4 from the thin part 4a, the top end 70a of the jig 70 abuts on a notch 23a. Then, when the jig 70 is twisted so as to be inclined in the front face direction of the waterproof case 4, the film unit with the lens is pressed to the inner face of the rear face part 33 of the waterproof case 4 by the jig 70, so that the aperture end of the front face part 32 is disengaged from the engaging groove 64 of the rear face part 33. Then, the film unit with the lens is detached from the front face part 32 together with the rear face part 33 of the waterproof case 4, so that it is taken out from the waterproof case 4.
