Claims (3)
- 鏡筒内に組み込まれるレンズユニットと、前記鏡筒を光軸方向に移動自在に保持するホルダと、このホルダの支持枠と、この支持枠と前記ホルダとの間に介在する高分子アクチュエータと、端子からの電圧の印加に応じて変位する前記高分子アクチュエータに形成した複数の光軸方向に変位可能な片状部である変位部と、前記鏡筒の撮像側端面に固定して前記変位部と係合可能な受部材とを備え、前記端子からの電圧の印加に応じて前記変位部を変位させ、その変位部の変位量に応じてレンズユニットを光軸方向に移動させて被写体とのピント合わせを自動化するように構成した撮像レンズユニットであって、前記ホルダと支持枠との重ね合わせ部に近接して該ホルダ又は支持枠の少なくとも一方に光軸と直交する方向に長く開口させた長孔状の開口部を形成して弾性変形可能なバネ片を形成し、このバネ片の付勢力によって前記端子を前記高分子アクチュエータ側に押し付けるとともに、前記ホルダ又は支持枠の外周面を覆う複数の側板部を有するカバーがホルダに保持されており、前記側板部によって前記開口部を塞ぐことを特徴とする撮像レンズユニット。
- 前記端子の端部より外部に露出して外部配線部材と接続する接続端子部をL字状に折曲形成し、この接続端子部を前記支持枠の外周面に形成する段差凹部に収納し、前記支持枠の外周面と前記接続端子部とをほぼ面一に連続させたことを特徴とする請求項1記載の撮像レンズユニット。
- 前記ホルダに係止爪を設け、この係止爪を前記カバーに形成する係止孔に係止して前記ホルダに前記カバーを保持したことを特徴とする請求項1記載の撮像レンズユニット。
