Patent ID: 8137010

Claim:
An imaging device configured to point an internal camera incorporated in a camera head toward an imaging area and take an image of a subject set in the imaging area, the imaging device comprising: a base located at a certain position that avoids interfering with the imaging area; a base-side arm structured to rise substantially upright from the base and to be extended from a side of the base over the imaging area; a head-side arm extended from the camera head to be transverse to an optical axis of the camera; and a head support assembly configured to support the camera head on the base-side arm via the head-side arm, such that an up-down positional relation in an imaging view field of the camera is kept unchanged relative to the subject set in the imaging area, regardless of a positional change of the base from the certain position to a different position that avoids interfering with the imaging area; wherein the base-side arm includes a first arm structured to rise substantially upright from the base, and a second arm supported in a pivotally rotatable manner on the first arm to change a geometrical configuration between a folding configuration to be folded back on the first arm and an extending configuration to be extended over the imaging area, and wherein the head-side arm partially overlaps the second arm to define an overlapping region, and the head support assembly has an arm support shaft provided at one end of the second arm in said overlapping region, said arm support shaft being configured to support the head-side arm in a manner pivotally rotatable relative to the second arm in a plane that is parallel to said imaging area when said second arm is disposed parallel to said imaging area.
