実用新案登録請求の範囲第１項に記載の瞼検知機
能を備えた眼科器械。[Scope of Claim for Utility Model Registration] 1. An illumination light source that illuminates the pupil area of the eye to be examined from above the eye in an instrument that projects a light beam onto the eye to be examined and observes or photographs the eye using the reflected light beam;
The image receiving means is arranged at a position conjugate with the pupil area and receives the corneal reflected image from the illumination light source, and the discriminating means determines the state of the eyelid based on whether the corneal reflected image by the image receiving means can be confirmed. An ophthalmological instrument equipped with an eyelid detection function. 2. An ophthalmological instrument equipped with an eyelid detection function according to claim 1, which stops the original measurement and photographing means of the ophthalmological machine based on the measurement data of the detection means.
