DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater photographing apparatus for observing a state of water or a water bottom or aquatic creatures such as fish living there.

[0002]

2. Description of the Related Art It is fun to observe the movement of aquatic organisms such as fish that inhabit underwater or the bottom of the sea, lake or pond.
2. Description of the Related Art Conventionally, observation of aquatic organisms is often performed by a diver bringing an underwater camera into the water and appreciating an image taken.

[0003] However, in order for ordinary non-divers to photograph aquatic organisms, the underwater camera must be submerged in the water, and in this case, there are too many restrictions and observation of aquatic organisms is extremely difficult. Have difficulty.

[0004] In addition, when fishing, it is a wish of an angler to see where the fish bites on the bait attached to the hook, but the conventional fishing tackle is attached to a fishing line and a tip of the fishing line. It was not possible to see the fish biting the bait because it consisted of a hook and weight.

[0005] However, a method has been proposed in which an underwater camera, which has been waterproofed, is submerged separately from the fishing line to photograph the fish that come to eat food. It is difficult to control the camera to point at aquatic organisms, and it is very difficult to control both the fishing line and the imaging camera.

Further, a method has been proposed in which a conventional camera that is not waterproofed is covered with a waterproof case, and underwater photography is performed using a waterproof signal line. However, the size of the entire apparatus is increased. There was a disadvantage.

Therefore, Japanese Patent Application Laid-Open No. 10-113109 discloses a small television camera (imaging device) for photographing aquatic organisms, a monitor television (image receiving device) for displaying images photographed by the small television camera on the ground, The control line input to the monitor television is transmitted as an optical signal to the small television camera, and the information of the image taken by the small television camera is transmitted to the monitor television as an optical signal. An underwater photographing apparatus provided with the apparatus has been proposed.

[0008]

However, since the optical fiber is not flexible, there is a problem that the fishing line made of the optical fiber is inconvenient to handle and easily broken.

Also, since the system is for transmitting an optical signal between a monitor television and a small television camera, a conversion device for converting an electric signal into an optical signal and a power supply for driving the conversion device are provided to the small television camera. However, there is a problem that a small TV camera has to be enlarged.

Further, when a small television camera is built in a float, the distance between the small television camera and the fishing hook is too large, so that the fish hooked on the fishing hook cannot be seen in a place where the water depth is large, and the small camera is simulated. When incorporated in the bait, the distance between the small TV camera and the fishing hook is too small, so that there is still a problem that the fish hanging on the fishing hook cannot be seen.
