Underwater photography device with rotation function {ROTATABLE UNDERWATER CAMERA APPARATUS}

The present invention relates to an underwater photographing apparatus having a rotating function, and more specifically, because of its compact structure, the structure is simplified and its volume is small, so that it is easy to handle for various purposes, and the manufacturing cost can be reduced. In addition, the present invention relates to an underwater photographing apparatus having a rotation function that can reduce power consumption and significantly improve utilization.

Underwater photography is carried out for various reasons. For example, underwater imaging is performed to investigate an underwater state such as a health state of the underwater bottom surface and a reproductive state of algae or the like that grows on the bottom surface, or to photograph an underwater image.

In the past, divers have taken a fixed underwater camera directly to shoot. However, since the operation is inconvenient, an underwater photographing apparatus has been proposed.
