Abstract

PURPOSE:To stably vary a panning angle and a tilting angle while the device itself is miniaturized by providing a variable member to vary the panning angle and the tilting angle of the photographing device onto an underwater stabilizing plate. CONSTITUTION:A pan angle drive section 4 is fixed with a guide plate 1 and consists of a motor rotating an arm 3 is direction of arrow A. A tilt angle drive section 5 is fixed to the arm 3 and consists of a motor rotating an submerged blimp 6 protecting a camera main body 8 a lens 7 or the like in the direction of arrow B. In driving the pan angle drive section 4, a force to rotate the flow guide plate 1 is exerted but the guide plate 1 receives the resistance of sea water sufficiently and almost not moved. While the arm 3 does not receive the sea water resistance in comparison with the resistance of the guide plate, it is stably rotated. As stated above, the arm 3 and the tilt angle drive part are fixed, but since the arm 3 and the blimp 6 connected freely turnably, the tilt angle is stably varied.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is underwater! ! ! This invention relates to two devices, particularly a photographing device that controls the photographing device from above the water surface.

<Description of Prior Art> In recent years, opportunities to dive into seawater and take photographs have been increasing. To take pictures here, Daiper himself brings his own photographic equipment into the ocean. At this time, it is difficult and dangerous to bring in the photographing equipment under adverse conditions, especially in deep sea or cold water. Therefore, there is a technique for changing the eight shadow directions of a photographing device by remote control from above the sea surface. However, although some diving devices incorporate a screw device or the like in order to change the pan angle or tilt angle, for example, the diving device itself or the screw itself tends to become larger.

<Object of the Invention> In order to solve the above-mentioned conventional problems, the present invention aims to provide an underwater photographing device that can reduce the size of the device itself and stably vary the pan angle and tilt angle.

For the above purpose, the photographing device is provided with an underwater stabilizer, and the underwater stabilizer is provided with a variable member for changing the photographing device and the pan angle and tilt angle of the photographing device.

<Example> An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic front view of the entire photographing device of the present invention including the camera body, and FIG. 2 is a side view of the photographing device of FIG.

Reference numeral 1 denotes a flow guide plate consisting of a flat plate that stabilizes the entire Mti shadowing device and the panning operation. This guide plate 1 is designed to balance the weight of the entire imaging device. 2 is a ring-shaped balancer guide that particularly stabilizes the tilting operation. A weight 2a is disposed on the balancer guide 2, which can be smoothly moved along the ring shape. Reference numeral 3 denotes an arm that connects drive units 4 and 5 that change the pan angle and tilt angle, respectively.

Reference numeral 4 denotes a pan angle drive section that performs a panning operation, and 5 a tilt angle drive section that performs a tilting operation.

The pan angle drive unit 4 is fixed to the guide plate 2 and consists of a motor that rotates the arm 3 in the rotational direction of arrow A. The tilt angle drive unit 5 is fixedly connected to the arm 3, and is connected to the camera body 8. It consists of a motor that rotates the underwater printer that protects the lens 7, etc. in the rotational direction of arrow B. Reference numeral 9 denotes an electric transmission cable for transmitting and receiving power and control signals to the motor of the pan angle drive unit 4, the motor of the tilt angle drive unit 5, camera control, lens control, and the like. The electrical transmission cable 9 is connected to a control device (not shown) on the sea surface. 11 is a wire for hanging the photographing device.

The operation will be explained based on the above configuration.

First, when trying to change the pan angle, by driving the pan angle drive section 4, the arm 3 stably rotates in the direction of arrow A without twisting the wire 11 much. Here, when the pan angle drive section 4 is driven, a force that tries to rotate the flow guide plate 1 also acts, but the flow guide plate 1 is sufficiently resisted by the seawater and becomes almost immobile. On the other hand, the arm 3 rotates stably without receiving much resistance from the seawater compared to the resistance from the flow guide plate. Furthermore, even when trying to stop the rotation, a stable stopping action can be obtained due to the action of the flow guide plate.

Next, when the tilt angle is to be changed, the underwater printer rotates in the direction of arrow B by driving the tilt angle drive unit 5.

As described above, the arm 3 and the tilt angle driving section are fixedly installed, but since the arm 3 and the printer are rotatably connected, the tilt angle can be varied. In this embodiment, a balancer guide 2 and a weight 2a are provided in order to more stably change the tilt angle. When the tilt angle changes, the weight constantly points in the direction of gravity, making it possible to stably change the tilt angle.

<Effect> As explained above, it is possible to stably change the pan angle and tilt angle with a simple configuration.
