Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a video aquarium that can freely display various aquatic creatures.

[Conventional technology] Conventionally, when exhibiting aquatic organisms in an aquarium or the like, reefs and aquatic plants are appropriately arranged in a tank filled with water, and aquatic plants such as shellfish and shrimp are placed as needed. The aquarium is equipped with small animals and an environment suitable for the aquatic creatures on display.

In addition, especially when displaying aquatic organisms that live in high water pressure, equipment is installed to maintain the tank at high pressure.

[Problems to be solved by the invention] However, in the above-mentioned aquarium, in order to maintain the health of aquatic organisms, feeding, water quality, and water pressure must be managed in a timely and appropriate manner.
When changing the type of aquatic organisms to be exhibited, there were problems such as the need for a large amount of time and effort to replace the aquatic organisms and reorganize the environment in the aquarium.

In view of the above-mentioned circumstances, this invention aims to diversify the types of aquatic organisms that can be exhibited by visualizing them, saves the trouble of feeding, water quality, and water pressure management, and increases the number of aquatic organisms to be exhibited. You can easily replace or reorganize the environment in the aquarium, and you can observe aquatic creatures in the same way as if you put them in a tank filled with water.
This was done in order to provide a video aquarium in which it is possible to easily see underwater creatures that are difficult to observe because they prefer darkness or holes.

[Means for Solving the Problems] The present invention is configured such that transparent plates are arranged side by side at a predetermined interval as the front wall of an aquarium for displaying aquatic organisms, and the space between the transparent plates can be filled with liquid. and extending from one corner of the transparent plate inside the transparent plate inside the aquarium to one corner of the opposite corner of the wall surface of the transparent plate of the aquarium, which is diagonal to the one corner, and having a width that is approximately the same as the inner dimension of the aquarium. A half mirror is provided at a predetermined angle with respect to the transparent plate, and a background in which a rock reef, aquatic plants, etc. imitating nature is arranged on the bottom plate of the aquarium on the semitransparent plate side of the half mirror,
An image display device is provided on the outer surface of the aquarium facing the transparent plate in the direction in which light is reflected via a half mirror.

[Function] Therefore, in the present invention, in front of the transparent plate,
By combining the background transmitted through the half mirror and the image of the image display device reflected by the half mirror through the liquid between the transparent plates, it is possible to observe the object as if it were in the liquid.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

Figures 1 and 2 show an embodiment of the present invention, in which the front part of an aquarium 1 for displaying underwater creatures is
A space 4 is created by erecting transparent plates 2 and 3 (for example, glass plates) parallel to each other at a predetermined interval in the front-rear direction.
The space 4 is filled with water, the lower end is brought into contact with the lower part of the rear surface of the transparent plate 3, the upper end is brought into contact with the upper part of the rear side wall 5 of the water tank 1, and both end parts are brought into contact with the water tank. A half mirror 8 that contacts the inside of the side walls 6 and 7 of the aquarium 1 is inserted at a predetermined angle with respect to the transparent plate 3, and a natural environment is placed on the bottom plate 9 of the aquarium 1 behind the half mirror 8. Simulated reef 1
0. Backscape 1 formed by arranging aquatic plants 11 etc.
2, and a video display device 13 is provided above the aquarium 1.
has been established.

In this embodiment, as the video display device 13,
A projection screen for displaying an image projected from a projector (not shown) is used, and the projection screen is arranged so as to face the transparent plate 3 in the direction in which light is reflected through the half mirror 8.
Further, as a medium for images to be projected on the image display device 13, a movie film in which many kinds of underwater creatures are photographed is prepared. In addition, the above-mentioned transparent plates 2 and 3
It is preferable to perform air ration or the like to give movement to the water filling the space 4 between them.

When a movie film that captures an underwater creature to be exhibited is selected and projected onto the image display device 13 using a projector, the image of the underwater creature displayed on the image display device 13 is reflected by the half mirror 8 and projected onto the front of the aquarium 1. It is projected in the direction of , and is observed through the water filling the space 4 of the transparent plates 2 and 3 together with the background 12 that is visible through the half mirror 8 as if it were underwater.

In the above-mentioned embodiment, the half mirror was provided toward the middle direction between the front and upper sides of the aquarium, and the video display device was provided above the aquarium. The video display device may be provided on the side of the aquarium, or the half mirror may be provided toward the middle direction between the front and the bottom of the aquarium, and the video display device may be provided below the aquarium. In addition, it can be used as a television screen instead of a projection screen as a video display device, and the video display device can be combined with a movable device controlled by a computer such as a robot so that it can be used in large aquariums. In addition, areas other than space 4 can be filled with water or liquid to enhance the effect of appearing underwater, or to raise aquatic creatures.
It goes without saying that various changes may be made without departing from the gist of the present invention, such as making it possible to observe it in combination with a video.

[Effects of the Invention] As explained above, the video aquarium of the present invention can provide various excellent effects as described below.

(1) It is possible to diversify the types of aquatic organisms to be exhibited, it is also possible to display aquatic organisms that are difficult to keep, and the types of aquatic organisms can be easily changed; Moreover, it can be observed in the same way as observing underwater creatures in an aquarium filled with water.

(2) Since there is no need to raise living organisms, the effort of feeding and water quality management can be saved.

(3) Since the background is not set underwater, it is possible to easily reorganize the environment.

(4) Paragraphs (1) to (3) can significantly reduce equipment costs and maintenance costs for aquariums.
