<p>PURPOSE:To enable swimmers to enjoy the feeling of being at the sea-bottom or in the river by forming the wall of a pool into such a screen as to enable an image, projected from an externally installed projector, to be visible from the inside, and installing the projector at least in one state between the movable and oscillating state. CONSTITUTION:A translucent screen film 30 is attached to the outer face of a side wall 11 corresponding to the short side of a pool 1. The side walls 13, 14 corresponding to the long sides of the pool 1 are provided with speakers 31, 32. A projector 2 is disposed outside of the side wall 11 so as to allow an image to be projected on the screen film 30 from the outside of the pool 1. The projector 2 is provided movably in the lateral direction X and longitudinal direction Y so as to enable swimmers in the pool 1 to see the image projected on the screen film 30.</p> |
