Description
請求項８記載のレンズ保持装置は、内側にレンズ保持部を有するレンズ鏡胴と、このレンズ鏡胴内に挿入されてレンズ保持部に周縁が保持されるレンズと、前記レンズ鏡胴内に挿入されてレンズ保持部との間で前記レンズの周縁を光軸方向に対して保持する請求項５ないし７いずれか記載のレンズ押え環とを具備しているものである。 The lens holding device described in claim 8 comprises a lens barrel having a lens holding portion on the inside, a lens inserted into the lens barrel and having its periphery held by the lens holding portion, and a lens pressing ring described in any one of claims 5 to 7, which is inserted into the lens barrel and holds the periphery of the lens in the optical axis direction between the lens barrel and the lens holding portion .
さらに、レンズ鏡胴12の内周面23に摺動可能に係合されるガイド部43により、レンズ鏡胴12内におけるレンズ押え環14の径方向位置を位置決めでき、係止部44の損傷などを防止できる。 Furthermore, the guide portion 43 slidably engaged with the inner peripheral surface 23 of the lens barrel 12 allows the lens press ring 14 to be positioned radially within the lens barrel 12, preventing damage to the locking portion 44.
