Abstract:
1. An ophthalmic apparatus comprising: an ophthalmic examination unit arranged to perform examination of an examinee's eye; an alignment state detection unit arranged to detect an alignment state of the ophthalmic examination unit with respect to the eye, the alignment state detection unit comprising a photographing optical system arranged to photograph an anterior segment of the eye and placed in the ophthalmic examination unit; a main base; a mobile base on which the ophthalmic examination unit is mounted, the mobile base arranged to be moved in a horizontal direction on the main base through operation of a control member by an examiner; a vertical driving mechanism arranged to move the ophthalmic examination unit vertically with respect to the mobile base through driving of a motor; a horizontal driving mechanism arranged to move the ophthalmic examination unit horizontally with respect to the mobile base through driving of a motor, a movable range in a right/left direction of the horizontal driving mechanism being established to be more than a predetermined pupillary distance; mode changeover means arranged to switch a mode between a manual mode of performing alignment of the ophthalmic examination unit with respect to each right and left eye in sequence through the operation of the control member, and a fully automatic mode of performing the alignment through driving of the driving mechanisms; and a control unit arranged to control the driving of the driving mechanisms based on a detection result by the alignment state detection unit, wherein the control unit starts, in a case where the fully automatic mode is established by the mode changeover means, the driving of the driving mechanisms based on a predetermined trigger signal which is emitted when the mobile base is placed at a predetermined position on the main base so as to perform the alignment.
