PROBLEM TO BE SOLVED: To provide a fundus camera capable of observing fundus oculi images on the same television monitor in either case of mydriatic photographing and non- mydriatic photographing, observing the fundus oculi images by visible light at the time of the mydriatic photographing and eliminating the possibility of the pupil contraction of an eye to be tested due to near sight by using an internal fixed visual mark at the time of the non-mydriatic photographing in the fundus camera capable of being shared for the mydriatic photographing and the non-mydriatic photographing. SOLUTION: This fundus camera is provided with an infrared light transmission mirror 95 freely insertably and detachably arranged in the optical path of a photographing optical system 53 for reflecting the visible light and transmitting infrared light and an internal fixed visual mark projection optical system G for projecting the internal fixed visual mark for guiding the line of sight of the eye E to be tested through the infrared light transmission mirror 95 to the eye E to be tested. Then, an infrared transmission filter 58 and an infrared cutting filter 94 as illumination switching means switch illumination light to the infrared light linked with the insertion to the optical path of the infrared light transmission mirror 95 and switch the illumination light to the visible light linked with the detachment from the optical path of the infrared light transmission mirror 95.
