    • A fundus photographing apparatus for photographing a fundus of an examinee's eye includes: a photographing part including a photographing optical system for photographing the fundus; a mechanism for moving the photographing part; a presenting part for presenting a fixation target to the eye; an alignment detecting optical system including a light receiving element to detect an alignment state of the photographing part; and a setting part for setting an alignment completion position in a back and forth direction of the photographing part relative to the eye based on the detected alignment state. The alignment completion position includes a first alignment completion position information to be set when an optical axis of the photographing part is in a predetermined range relative to a corneal vertex of the eye and a second alignment completion position information to be set when the optical axis is apart from the predetermined range.
    • 用于拍摄受检者眼底的眼底拍摄设备包括:拍摄部分,包括用于拍摄眼底的拍摄光学系统; 用于移动拍摄部件的机构; 用于向眼睛呈现固定目标的呈现部分; 对准检测光学系统,包括用于检测拍摄部分的对准状态的光接收元件; 以及设定部,其基于检测出的对准状态,相对于眼睛来设定拍摄部的前后方向的对准完成位置。 对准完成位置包括当拍摄部分的光轴相对于眼睛的角膜顶点处于预定范围内时要设置的第一对准完成位置信息和当光轴为眼睛时要设置的第二对准完成位置信息 除了预定范围。
