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.
摘要翻译：眼科装置允许用于眼底观察的定影目标投影单元将用于眼底观察的固定目标投影到与观察光学系统的光路中心不重合的位置，但对应于前方的固定目标的位置预测眼睛观察。因此，操作者不需要再次执行定位和定影引导操作，从而有助于缩短成像时间，并且在整体操作中有较少的复杂性和麻烦。

摘要： A focusing unit can be inserted into and removed from an illumination light path by rotating around a supporting portion. An index light source, a green LED, is attached to the bottom of a base. A transparent acrylic-resin disk is fixed to the base. A deflection prism is attached to the bottom of the disk. A beam from the light source enters the deflection prism. A focus index forming portion is provided on the top of the disk. In the center of a light-shielding portion is formed a slit-like opening, under which split prisms are provided. Deflected by the prisms, the beam from the light source is split into two, right-half and left-half, directional beams, and combined with an illumination optical system, in the form of two slit images, at the opening.

摘要： If a position of a focus lens is greatly displaced from a focus state when automatic focusing is started, and pattern recognition cannot be performed, the process proceeds to step S3. In step S3, the lens is sequentially driven until pattern recognition can be performed. If it is determined that the pattern recognition can be performed in step S2, a focus detection range is determined in S4. In step S5, an AF evaluation value of the range is calculated, and the value is stored in step S6.
