Claims (5)
- 被検眼の検査等を行うための光学系収納部が搭載され、固定基台上を水平方向に移動可能な移動台を備える眼科装置において、前記移動台に上下方向に回転可能に軸支されたアームと、該アームに保持され前記基台に押さえ付けられる固定部材と、前記固定部材を前記基台から離れた第1位置と前記基台に押さえ付ける第2位置とに移動させるために前記アームを回転させる操作部材であって、前記アームの回転中心に対する距離に関して、前記固定部材が配置された距離よりも長い距離に配置された操作部材と、該操作部材の操作により前記固定部材が前記第1位置、第2位置に移動させたときに前記アームの回転を制限する回転制限手段と、を備えることを特徴とする眼科装置。
- 請求項1の眼科装置において、前記固定部材を前記基台に押さえ付けさせる力を加える押え力付加部材を備えることを特徴とする眼科装置。
- 請求項2の眼科装置において、前記押え力付加部材は前記固定部材を前記基台に押さえ付ける付勢部材であり、さらに、前記移動台には前記固定部材が前記基台から離れるように前記アームを上方に付勢する第2の付勢部材が設けられていることを特徴とする眼科装置。
- 請求項2の眼科装置において、前記押え力付加部材は前記固定部材を前記基台側へ引き付ける磁石にて構成されていることを特徴とする眼科装置。
- 請求項2の眼科装置において、前記操作部材は、アームの回転方向に回転可能に前記移動台に軸支されたカムであって、前記アームの一端と接する面を持つカムと、該カムをその軸支中心に回転させる操作レバーとからなる構成であり、前記カムにおける前記アームの一端と接する面には、その回転中心に対して同一半径の第1面と該第1面より半径方向に短い第2面とが形成されており、前記回転制限手段は前記カムの第1面と第2面の切替えにより前記アームの回転の制限とその解除をする構成とされていることを特徴とする眼科装置。
