Abstract:
1. An imaging unit comprising: an incident-side reflecting surface provided in a casing and that reflects light emanating from an object and entering said casing from the outside of said casing in a thickness direction of said casing, so that said light reflected by said incident-side reflecting surface travels along a lengthwise direction of said casing that is orthogonal to said thickness direction of said casing; a movable lens group, comprising a plurality of relatively movable lens groups, provided in said casing as a power-varying lens group and allows said light, which is reflected by said incident-side reflecting surface, to pass through said movable lens group, said movable lens group being movable along said lengthwise direction of said casing, one of the plurality of lens groups being positioned closest to an image; an exit-side reflecting surface provided in said casing and that reflects said light, which is incident on said exit-side reflecting surface after passing through said movable lens group, so that said light travels from said exit-side reflecting surface in said thickness direction of said casing; an image sensor provided in said casing and that receives said light that has traveled from said exit-side reflecting surface; and a plurality of light shield frames provided in said casing between said one of the lens groups of said plurality of relatively movable lens groups of said movable lens group and said exit-side reflecting surface, said plurality of light shield frames being arranged in said lengthwise direction of said casing and moving in said lengthwise direction of said casing when said movable lens group performs a power-varying operation.
