Example 1

The present invention incorporates a video camera or a general camera (2) in the camera built-in case (1) made of a transparent body by the impact protection material 2A, the lens portion (2B) of the camera (2) is a camera built-in case (1) The front side of the transparent plate 1A is positioned facing the rear side of the camera built-in case (1) is screwed to the transparent cover (1B). At this time, the transparent cover 1B and the built-in case 1 keeps airtight.

Then, the male screw portion 3A which is formed on the outer inner circumferential surface of the front transparent plate 1A of the camera interior case 1 at the rear end side of the chamber 3 of the transparent body for constructing the shooting distance of the construction body 3A. ) While screwing it tightly.

The chamber 3 of the transparent body is formed of a rectangular sealed transparent box, and the water supply port 3B is placed on one side of the upper side of the chamber 3 of the transparent body so that 3C of transparent water before shooting is transparent inside the chamber 3 of the transparent body. Fill it with In addition, each side of the chamber 3 of the transparent body has a lamp bracket (3D) and the lamp (4) is fixed to each installation. At this time, the conductor or battery for power supply of the lamp 4 is omitted since it is a general matter. However, it is preferable that the conducting wire is processed so as not to interfere with photographing and connected to a battery (not shown) built in the interior case 1.

Then, the front side of the chamber (3) of the transparent body as the airtight coupling frame (5), it is configured to combine the transparent bag 6 for the interview with the soft structure. The transparent bag 6 for constructing the interview is supplied and filled with transparent clean water 6B before shooting by the water supply port 6A on one side.

In the above, the water supply port 3B, 6A is provided with a check valve, not shown, and may be used in the chamber 3 and the transparent bag 6 of the transparent body without supplying clean water. 3 (b) is a modified example of the above embodiment, in order to widen the photographing angle, the chamber 3 of the transparent body is formed to be wider toward the front side.

In FIG. 1 thru | or 3 (a) and 3 (b), 1D is a handle and 1E is a camera operation button part.

According to the present invention having such a configuration, as shown in FIG. 7, the imaging apparatus A is immersed in the water by a diver, and the sixth (a) is applied to the uneven surface 7A of the underwater construction 7 which is the object to be photographed. As shown in the drawing, the state of the structure 7 is photographed by operating the camera operation button portion 1E in a state where the transparent bag 6 for constructive interview is interviewed.
