Patent ID: 8851751

Claim:
An X-ray imaging apparatus, comprising: an imaging unit configured to receive electric power via a first power feeding mechanism provided in a back surface opposed to an imaging surface having a photoelectric conversion element for acquiring an X-ray image; a pedestal including a second power feeding mechanism configured to feed the electric power to the imaging unit via the first power feeding mechanism; a holder disposed on the pedestal and configured to hold the imaging unit so that a position of the first power feeding mechanism coincides with a position of the second power feeding mechanism; a moving unit configured to move the holder so that the first power feeding mechanism is moved along with the second power feeding mechanism to an arbitrary position in a plane parallel to the imaging surface of the imaging unit and/or the first power feeding mechanism is rotated by an arbitrary angle with respect to an axis perpendicular to the imaging surface, within a range in which electric power is fed from the second power feeding mechanism to the first power feeding mechanism; and a power feeding port configured to feed electric power to the imaging unit via the first and second power feeding mechanisms.
