PROBLEM TO BE SOLVED: To obtain varied images by moving the image of a rotating image body on a projector not only in the rotating direction but also each and forth, and to project a clear image by making the center of the rotating image body and the center of the projector eccentric. SOLUTION: A cylindrical rotating image body 3 which is formed of a hard synthetic resin material and on which an image is drawn, is arranged between a light source 2 and a projector 4. The center of the projector 4 is concentric with a central point of a base stand 1, and the center of the light source 2 is not concentric with the center of the base stand 1 and the projector 4, but is eccentric, and the rotation center of the rotating image body 3 is concentrically arranged with the center of the light source 2. The image by the rotating image body 3 projected by the projector 4 changes not only in the rotation direction but also back and forth by making the rotation center of the image body 3 and the center of the projector 4 eccentric. A clear image can be projected in the part 41 by arranging the image body 3 in a state of approaching the projector 4 in the eccentric side part 41 of the projector 4. |
