Claims (4)
- レンズを内蔵し、回転駆動せずに光軸方向に移動可能な直進筒と、該直進筒の外周面から前記レンズの光軸に直交する方向に突出した設けられた1又は複数の案内軸と、前記直進筒の外周に設けられ、内周面に前記案内軸を嵌合するカム溝を有し、光軸方向に移動可能であり、回転することにより前記直進筒を光軸方向に移動する回転移動筒とを有するレンズ鏡胴において、
前記回転移動筒に、内周面から前記レンズの光軸に直交する方向に突出した補強軸を設け、前記直進筒の後端部に、前記補強軸の側部と一定距離を隔てた接触面を有する切欠き部を設けたことを特徴とするレンズ鏡胴。 - 前記直進筒の接触面と前記補強軸との間の一定距離は、前記直進筒にあらかじめ定めた大きさを超えた負荷が加えられたとき、直進筒の接触面が前記補強軸に接触する距離である請求項1記載のレンズ鏡胴。
- 前記回転移動筒に有するカム溝の軌跡は、回転移動筒が回転を開始してからあらかじめ定めた一定回転角までは前記レンズ側に対する変位が少ない小さな傾斜角の軌跡で形成され、前記一定回転角を越えてから前記レンズ側に対する変位が大きい大きな傾斜角の軌跡で形成され、前記直進筒の接触面の軌跡は、前記回転移動筒に設けた前記カム溝の小さな傾斜角の軌跡と同一になるように直進筒の切欠き部の形状を形成する請求項1又は2記載のレンズ鏡胴。
- 請求項1乃至3のいずれかに記載のレンズ鏡胴を有することを特徴とする撮影装置。
