Imaging apparatus having bending optical element

摘要

An imaging apparatus includes an imaging optical system, a bending optical element and an image sensor; an inclination adjusting plate which mounts the image sensor onto a housing with a pair of opposed sides of the image sensor extending in a direction orthogonal to a pre-bending optical axis, of the imaging optical system; a pair of end portions formed on the inclination adjusting plate and positioned outside the pair of opposed sides of the image sensor; a swing fulcrum formed between an inner end portion, which is closest to the pre-bending optical axis, and the housing; and an inclination adjuster provided between an outer end portion, which is farthest from the pre-bending optical axis out, and the housing, to make the inclination adjustment plate swing about the swing fulcrum to adjust the inclination adjustment plate.

主权项

1. An imaging apparatus comprising:
an imaging optical system including at least one lens group, at least one bending optical element which bends a light bundle emanating from an object, and an image sensor having a rectangular shape, in a plan view thereof, which lies on a post-bending optical axis of said imaging optical system, said post-bending optical axis being optically bent by said bending optical element; a housing which supports said imaging optical system; an inclination adjusting plate which mounts said image sensor onto said housing with a pair of sides of said image sensor that are opposed to each other extending in a direction orthogonal to a pre-bending optical axis, of said imaging optical system, before being optically bent by said bending optical element; a pair of end portions formed on said inclination adjusting plate and positioned outside said pair of opposed sides of said image sensor, respectively; a swing fulcrum formed between an inner end portion, which is closest to said pre-bending optical axis out of said pair of end portions, and said housing; and an inclination adjuster comprising a pair of adjustment screws, which is provided between an outer end portion, which is farthest from said pre-bending optical axis out of said pair of end portion, and said housing, to make said inclination adjustment plate swing about said swing fulcrum to adjust an inclination of said inclination adjustment plate.
