Claims (1)
- レンズを保持し、外周に突出するカム突起を有するレンズ保持枠と、
前記レンズ保持枠を内周に収納する鏡筒を有し、前記カム突起を前記鏡筒の外周に突出した状態で前記レンズ保持枠を光軸方向に移動自在に支持する固定筒と、
前記鏡筒の外周のうちの光軸方向に沿った前後に前記外周から突出してそれぞれ設けられている前・後規制部材と、
前記前・後規制部材により前記鏡筒の外周で光軸方向への移動を阻止した状態で光軸を中心とする周方向に回転自在に支持されており、前記カム突起に光軸方向から当接するカム面を有し、前記周方向への回転に対して前記カム面の光軸方向への変位によりレンズ保持枠を光軸方向に移動するカム環と、
前記鏡筒の外周に設けられており、前記カム突起をカム面に向けて付勢する付勢手段と、
前記カム環を前記鏡筒の外周に光軸方向に沿って挿入するときに、前記カム面から光軸方向の前方に向けて前記前規制部材を逃がすために前記カム環に設けられた切り欠き部と、
前記カム環を前記鏡筒に取り付けた後に、前記周方向での回転位置のうちの前記切り欠き部と前記前規制部材とが一致する着脱位置に前記カム環が回転しないように、前記カム環の回転を規制する回転規制手段と、を備え、
前記回転規制手段を、撮影で使用する前記カム面の範囲の周方向に沿った両端のうちの少なくとも一端に設けられ、光軸と平行なストッパ面と、前記ストッパ面に前記周方向から当接する前記カム突起と、で構成したことを特徴とするレンズ移動装置。
