Description

（１）本開示の第１態様に係る検眼装置は、検査窓に光学素子を切り換え配置する左右一対のレンズ室ユニットを備える眼屈折力測定ユニットと、を備え、前記検査窓を覗く被検眼に検査視標を呈示する検眼装置において、被検眼が正面方向に呈示される視標を見るために設定された基準軸上に配置された凹面ミラーと、視標を表示するディスプレイと、を有し、前記ディスプレイからの視標光束を前記凹面ミラーで反射させて、被検眼に視標を呈示する視標呈示ユニットと、前記眼屈折力測定ユニットを被検眼の眼前の検査位置と，退避位置と，の間で移動可能に支持する支持手段であって、前記視標呈示ユニットに設けられた支持手段と、を備えることを特徴とする。 (1) An optometry apparatus according to a first aspect of the present disclosure includes an eye refractive power measurement unit including a pair of left and right lens chamber units that switch and arrange optical elements in an examination window, and the eye to be examined looking into the examination window. An optometry apparatus that presents an inspection optotype having a concave mirror disposed on a reference axis that is set for viewing an optotype in which the subject's eye is presented in the front direction, and a display that displays the optotype. The target luminous flux from the display is reflected by the concave mirror to present the visual target to the eye to be examined, and the eye refractive power measurement unit is inspected before the eye of the eye to be examined, and the retracted position; , Movably supporting means, and supporting means provided in the optotype presenting unit.
