Description

【００１０】
（３）（１）の眼科装置において、前記判定手段は前記瞼位置検出手段により検出された瞼位置の経時変化に基づいて瞼が最上位置に移動したことを検知する最上位置検知手段を備え、瞼が最上位置に移動したことが検知された場合に前記検査手段による検査実行を可能と判定することを特徴とする。0010
(3) In the ophthalmic apparatus of (1), the determination means includes the uppermost position detecting means for detecting that the eyelid has moved to the uppermost position based on the time course of the eyelid position detected by the eyelid position detecting means. When it is detected that the eyelid has moved to the uppermost position, it is determined that the inspection can be performed by the inspection means.

（４）被検眼を撮影又は被検眼の特性を測定する検査手段を具備する眼科装置において、被検眼前眼部に検出光を投光する検出光投光手段と、前記検出光による前眼部からの反射光を受光する受光手段であって、被検眼角膜と略共役な位置で被検眼の上下方向に検出面を持つように配置された位置検出素子を有する受光手段と、前記位置検出素子からの出力信号に基づいて被検眼の瞼の移動位置を経時的に検出する瞼位置検出手段と、検出された瞼位置の経時変化に基づいて瞼が最上位置に移動したことを検知する最上位置検知手段と、瞼が最上位置に移動したことが検知された場合に前記検査手段の検査実行を制御する制御手段と、を備えることを特徴とする。0011
(4) In an ophthalmic apparatus provided with an inspection means for photographing the eye to be inspected or measuring the characteristics of the eye to be inspected, the detection light projection means for projecting the detection light to the anterior eyelid to be inspected and the anterior eye portion by the detection light. A light receiving means that receives light reflected from the eye and has a position detecting element arranged so as to have a detection surface in the vertical direction of the eye to be inspected at a position substantially conjugate with the cornea of the eye to be inspected, and the position detecting element. The eyelid position detecting means for detecting the movement position of the eyelid of the eye to be inspected over time based on the output signal from, and the uppermost position for detecting that the eyelid has moved to the uppermost position based on the detected change in the eyelid position with time. It is characterized by including a detecting means and a control means for controlling the inspection execution of the inspection means when it is detected that the eyelid has moved to the uppermost position.

Claims

In an ophthalmologic apparatus including an inspection unit that photographs an eye to be inspected or measures characteristics of the eye to be inspected, a detection light projection unit that emits detection light to an anterior eye of the eye to be inspected, and a reflection from the anterior eye by the detection light A light receiving means for receiving light, the light receiving means having a position detecting element arranged to have a detecting surface in a vertical direction of the eye to be examined at a position substantially conjugate with the cornea of the eye to be inspected, and an output from the position detecting element Eyelid position detecting means for detecting the position of the eyelid of the subject's eye over time based on a signal; and determining means for determining whether or not to execute the inspection by the inspection means based on the detected eyelid position.
