IMAGING DEVICE
First Claim
1. An imaging device comprising:
- a housing including a first photographing aperture and a second photographing aperture which are open toward opposite directions;
an image pickup device provided in said housing;
a main optical system which forms incident light from said first photographing aperture onto an imaging surface of said image pickup device, said main optical system defining a main optical axis extending from said first photographing aperture to said image pickup device; and
an insertable optical element which is movable in an inserting/removing direction between an insertion position in an optical path of said main optical system and a removed position out of said optical path of said main optical system, wherein said insertable optical element constitutes at least a part of a sub-optical system which forms incident light from said second photographing aperture onto said imaging surface of said image pickup device when said insertable optical element is positioned at said insertion position, said sub-optical system defining a sub-optical axis extending from said second photographing aperture to said image pickup device via said insertable optical element,wherein, when said insertable optical element is positioned in said insertion position, said sub-optical axis is offset from said main optical axis toward said removed position of said insertable optical element in said inserting/removing direction.

Abstract
An imaging device includes a housing including first and second photographing apertures which are open toward opposite directions; an image pickup device provided in the housing; a main optical system forming incident light from the first photographing aperture onto an imaging surface of the image pickup device; and an insertable optical element movable between an insertion position in an optical path of a main optical system and a removed position out of the optical path of the main optical system, the insertable optical element constituting at least a part of a sub-optical system which forms incident light from the second photographing aperture onto the imaging surface when at the insertion position. When the insertable optical element is positioned in the insertion position, the sub-optical axis is offset from the main optical axis toward the removed position of the insertable optical element in the inserting/removing direction.
