FIELD: video- and photo equipment. ^ SUBSTANCE: device for making video films and photographs has container to place filming equipment and ring-shaped housing. Cap provided with off-center window covered with glass is mounted relatively edge of ring-shaped case. Glass rests against toroid-sectioned ring-shaped glands. There are fabrication holes in cap to install lock and control buttons. Thread holes are made at the side adjacent to edge; cap is mounted against those holes. Spring provides steady elastic position of buttons relatively edges of blind holes. Inner surface of housing has to be ring-shaped surface provided with faces and ring-shaped grooves. Case provided with cap is mounted at the side of edge of cap. The case has reed relays provided with conductors; case is crossed by holes. Cap is crossed by thread holes and holes. Unit is mounted close to outer side of glass to make video films or photography. To make connection between reed relays and conductors the member is used which is installed inside control buttons made in form of spheroids and having coves to interact with human being and to keep fast orientation of position of lock and control buttons. ^ EFFECT: improved illumination intensity of object at depths of 0 to 160 meters. ^ 22 dwg |
