PROBLEM TO BE SOLVED: To achieve the miniaturization of an imaging apparatus by arranging a lens driving mechanism excellent in strength and accuracy with good space efficiency, in the imaging apparatus for moving two lens groups constituting an inflection optical system along an optical axis.SOLUTION: A first movable frame and a second movable frame holding movable lens groups respectively are supported to be movable in an optical axis direction, between a first reflection element and a second reflection element constituting the inflection optical system. The respective movable frames are moved by the rotations of a first lead screw and a second lead screw provided on both sides across an optical path between the first reflection element and the second reflection element, when the imaging apparatus is viewed from an object side. A first motor for rotationally driving the first lead screw is arranged in the back-side space of the reflection surface of the first reflection element and a second motor for rotationally driving the second lead screw is arranged in the back-side space of the reflection surface of the second reflection element. |
