Abstract

In an imaging device 100, as a base 110 is moved from a certain position on an upper side of an imaging area SA to a different position on a left side of the imaging area SA, a camera head 150 is pivotally rotated together with a head-side arm 160 relative to a second arm 132. Such combination of the movement of the base 110 with the pivotal rotation of the camera head 150 changes the operation mode of the imaging device 100 from a first working mode to a second working mode and enables the imaging device 100 to take images in the second working mode. Regardless of the positional change of the base 110 from the position on the upper side of the imaging area SA to the position on the left side of the imaging area SA with the change of the operation mode of the imaging device 100 from the first working mode to the second working mode, an up-down positional relation in an imaging view field of an internal camera, which is incorporated in the camera head 150 and is operated to shoot downward and take an image of a shooting object sheet ST set in the imaging area SA, is kept unchanged relative to the shooting object sheet ST.

Dependent claims

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.

An imaging device comprising:

an internal camera incorporated in a camera head configured to point the internal camera toward an imaging area defined in a first plane, and take an image of a subject set in the imaging area;
a base to be located at a given position outside the imaging area;
a base-side arm structured to rise substantially upward from the base and to be extended from the base and over the imaging area, said base-side arm having at least one pivotally rotatable joint having an axis of rotation parallel to said first plane;
and
a head-side arm extended from the camera head and transverse to an optical axis of the camera, said head-side arm being connected to said base-side arm by a joint which, when extended, is pivotally rotatable about an axis of rotation transverse to said first plane;
the base, the camera head, the base-side arm and the head-side arm, being thereby configured 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 given position to a different position outside the imaging area;
wherein the base-side arm includes a first arm structured to rise substantially upward from the base, and a second arm supported in a pivotally rotatable manner on the first arm about said axis of rotation parallel to said first plane, to change a geometrical configuration between a folded configuration in which said second arm is folded back on the first arm, and an extended configuration in which said second arm is extended over the imaging area, and
wherein the head-side arm partially overlaps the second arm to define an overlapping region, and said joint connecting said head-side arm to said base-side arm is arranged at one end of the second arm in said overlapping region, and configured to support the head-side arm in a manner pivotally rotatable relative to the second arm in a plane parallel to said imaging area when said second arm is disposed parallel to said imaging area, about said axis of rotation transverse to said first plane.
