明装置付スケールを備えた接眼レンズ機構。 A scale is formed on the optical axis by depositing a material with high reflectivity on the joining inclined surface of the prism, and the prism is placed at the focal plane position of the eyepiece system, and the light source that illuminates the scale is placed near the prism. A dimmer mechanism for adjusting the brightness of the light source is attached to the light source, and the eyepiece tube, which is housed in a box that supports the eyepiece system, is set so as to be movable in the optical axis direction, thereby changing the field of view of the scale. An eyepiece mechanism equipped with a scale with an illumination device, characterized in that it can freely appear and disappear inside the eyepiece mechanism.
