Patent ID: 8485726

Claim:
An X-ray imaging apparatus, comprising: an imaging unit having an imaging unit power feeding mechanism configured to receive electric power from an external device; a pedestal including a pedestal power feeding mechanism configured to feed the electric power to the imaging unit; and a holder configured to position and hold the imaging unit so that a position of the imaging unit power feeding mechanism coincides with a position of the pedestal power feeding mechanism; wherein the holder includes: a guiding portion configured to enable translation movement of the holder to a position within a plane that is in parallel with an imaging plane of the imaging unit and/or to enable rotation of the holder to an angle with respect to an axis vertical to the imaging plane; and a power feeding port configured to, in a state where the imaging unit is combined with the holder, enable the imaging unit power feeding mechanism to receive the electric power even if the imaging unit power feeding mechanism is moved with respect to the pedestal power feeding mechanism; wherein the imaging unit power feeding mechanism includes line-shaped electrodes and the pedestal power feeding mechanism includes point-shaped electrodes, and wherein the imaging unit receives the electric power when the line-shaped electrodes of the imaging unit power feeding mechanism contact the point-shaped electrodes of the pedestal power feeding mechanism.
