Abstract: An ophthalmologic apparatus includes: a head unit having an optical system capable of receiving light reflected from a subject's eye; a drive mechanism that movably holds the head unit; an alignment detection unit that detects a position of the subject's eye relative to the head unit; and a control unit that controls the drive mechanism. The drive mechanism includes at least two arms rotatably connected together, at least two first rotation support mechanisms and at least three second rotation support mechanisms which allow the head unit to move, and at least five driving units for driving the rotation support mechanisms. The control unit is capable of controlling the driving units using a measurement result of the alignment measuring unit to align the head unit and the subject's eye with each other.

Abstract: A fundus observation apparatus includes an optical system, two concave mirrors, and a holding member. The optical system is configured to project light from a light source onto a fundus of an eye to be examined, and to receive returning light from the fundus. The two concave mirrors have concave reflective surfaces, respectively, configured to guide the light from the optical system to the fundus, and to guide the returning light to the optical system. The holding member is configured to be capable of holding the two concave mirrors in a state where the concave mirrors are arranged on both sides of the holding member so that the concave mirrors are positioned in a default relative position in a predetermined one-dimensional direction or predetermined two-dimensional directions.
