Claims (1)

[Claims for Utility Model Registration] (1) Regarding the objective optical system facing the subject's eye, the subject's eye is A fundus camera comprising a fundus illumination system that illuminates the fundus, and a fundus photographing system that captures an image of the fundus of the eye to be examined through the objective optical system and the central opening of the perforated mirror, wherein the central opening of the perforated mirror a two-hole diaphragm located nearby and fixed in the optical axis direction and the optical axis perpendicular direction, and provided with two apertures so as to extract the fundus reflected light flux passing through the pupil of the subject's eye as two different areas;
A shutter plate provided on the opposite side of the objective optical system in the optical path with respect to the two-hole diaphragm, which includes a fundus-reflected light flux that is restricted by the two-hole diaphragm and passes through two different regions of the pupil of the eye to be examined; A shutter plate is provided with a single aperture for selectively taking out only one of the apertures, and is fixed in the direction of the optical axis and movable in the direction perpendicular to the optical axis. A fundus camera characterized in that it enables stereoscopic vision by observing two fundus photographs taken through an aperture. (2) The fundus camera according to claim 1, wherein the movement of the shutter plate is executed at the same time as the initial photographing of the fundus camera is completed.
