Claims

[Claims for Utility Model Registration] The tips of a large number of optical fibers are appropriately arranged on a display surface, and the base ends of these optical fibers are placed together near a light source so that the light from the light source passes through a drum filter. The display device is configured to perform a predetermined display by scattering the colored light on the display surface through the optical fibers after coloring the drum filter, the drum filter being a transparent drum body;
Consisting of a plurality of colored rings with predetermined color patterns applied to the outer or inner circumferential surface of the drum body using light-transmitting paint, and each of these colored rings is removably fitted to the outer or inner circumference of the drum body. A drum filter that is characterized by:
