Patent ID: 8107004

Claim:
An imaging device comprising: an imaging optical system including at least one movable optical element; an image sensor, an imaging surface of which lies on an image-forming plane of said imaging optical system; a single circuit board having a planar and rectangular shape; an image processing circuit for processing an image signal output from said image sensor and a drive circuit for said movable optical element; and an actuator provided to drive the at least one movable optical element, said drive circuit configured to drive said actuator, wherein said image sensor, said image processing circuit and said drive circuit are mounted on said circuit board along a longitudinal direction thereof, wherein said image processing circuit and said drive circuit are disposed on said circuit board in that order from a side closer to said image sensor, wherein said movable optical element is movable in a direction of a primary optical axis of said imaging optical system, wherein said imaging optical system comprises an incident-side prism and an exit-side prism which are disposed at opposite ends of said primary optical axis to bend said opposite ends of said primary optical axis at right angles, respectively, and wherein said circuit board is parallel to said primary optical axis, includes said image sensor on a surface of said circuit board which faces an exit surface of said exit-side prism, and further includes said drive circuit so that said drive circuit is positioned in a close vicinity of said incident-side prism.
