    • An objective refraction measurement apparatus includes a separate chart having a pair of charts arranged separately, an optical system for projecting the separate chart to an eye to be examined through a focusing lens and a diaphragm having a pair of through holes arranged corresponding to the separate arrangement of the pair of charts, an operating unit for performing focusing operation to the eye, and a control unit for moving the focusing lens on the basis of the focusing operation along the optical axis direction by the operating unit to obtain the projection images of the pair of charts in the separate chart to the eye in an identical condition or a non-identical condition, thereby to perform a subjective measurement of the eye.
    • 客观折射测量装置包括具有单独布置的一对图表的单独图表,用于通过聚焦透镜将分离图表投影到待检查眼睛的光学系统和具有对应于分离布置的一对通孔的隔膜 的一对图表,用于对眼睛进行聚焦操作的操作单元和用于通过操作单元沿着光轴方向的聚焦操作来移动聚焦透镜的控制单元,以获得该对的投影图像 在相同条件或不相同条件下,将单独图表中的图表与眼睛进行对比,从而进行眼睛的主观测量。

    • An imaging unit includes a mount unit, an imaging element unit, a plurality of elastic members, a plurality of adjusting screws, and at least one restricting member. The mount unit is configured to support the interchangeable lens unit. The imaging element unit is disposed apart from the mount unit and is configured to produce image data for the subject by opto-electrical conversion. The plurality of elastic members is disposed in a compressed state between the mount unit and the imaging element unit. The plurality of adjusting screws is mounted to the mount unit and/or the imaging element unit to adjust the distance between the mount unit and the imaging element unit. The restricting member is mounted to the mount unit and/or the imaging element unit and configured to restrict the imaging element unit from moving close to the mount unit against the elastic force of the elastic members.
    • 成像单元包括安装单元,成像元件单元,多个弹性构件,多个调节螺钉以及至少一个限制构件。 安装单元构造成支撑可更换镜头单元。 成像元件单元与安装单元分开设置,并且被配置为通过光电转换来产生对象的图像数据。 多个弹性构件以安装单元和成像元件单元之间的压缩状态设置。 多个调节螺钉安装到安装单元和/或成像元件单元以调节安装单元和成像元件单元之间的距离。 限制构件安装到安装单元和/或成像元件单元,并且被配置为克服弹性构件的弹力来限制成像元件单元靠近安装单元移动。
