摘要： An ophthalmic apparatus allows a fixation-target projecting unit for fundus observation to project a fixation target for fundus observation onto a position not coinciding with a center of a light path of an observation optical system but corresponding to a position to which a fixation target for anterior-ocular-observation is projected. Thus, it is not necessary for an operator to perform positioning and fixation guiding operations again, thereby contributing to a shorter imaging time and less complexity and trouble in the overall operation.
