Abstract
Light emitted from a light source is converted into ultraviolet-and-blue light, green light, and red light, in that order, by a first wheel. When a second wheel inserts a transparent member into the optical path, the ultraviolet-and-blue light, the green light, and the red light enter a light guide. On the other hand, when the second wheel inserts a fluorescence observation filter into the optical path, ultraviolet-and-blue light is converted to ultraviolet light and then enters the light guide, while the green light is blocked and the red light enters the light guide.
