Summary: | PROBLEM TO BE SOLVED: To provide a lens moving mechanism that is lightweight, has high rigidity, and can prevent the occurrence of bending.SOLUTION: A lens moving mechanism 1 comprises: a lens mount 2 on which a lens 100 projecting light is mounted; a guiding part 30 that supports the lens mount 2 and guides the lens mount 2 in a three-axis orthogonal direction containing an optical axis direction of light; and a frame member 20 to which the guiding part 30 is fixed. The guiding part 30 includes a plurality of linear movement guiding devices 60 having: track rails 61 fixed to the frame part 20; and slider blocks 62 moving along the track rails 61. A plurality of the track rails 61 are coaxially arranged on the frame part 20.SELECTED DRAWING: Figure 2
【課題】撓みの発生を抑制でき、軽量かつ高剛性のレンズ移動機構の提供。【解決手段】レンズ移動機構1は、光を投射するレンズ100が取り付けられるレンズマウント2と、レンズマウント2を支持すると共に、該レンズマウント2を、光の光軸を含む3軸直交方向に案内する案内部30と、案内部30が固定されるフレーム部20と、を備え、案内部30は、フレーム部20に固定される軌道レール61と、軌道レール61に沿って移動するスライダブロック62と、を備える直動案内装置60を複数備え、フレーム部20に、軌道レール61が、同軸上で複数配置されている、という構成を採用する。【選択図】図2 |
