Abstract: A radiography apparatus includes an operation controller that invalidates an operation of a collimator using a first operating unit in a case where a radiation generation unit is present vertically downward relatively to a radiography unit, and validates the operation of the collimator using the first operating unit in a case where the radiation generation unit is present vertically upward relatively to the radiography unit.

Abstract: The radiography apparatus includes: an irradiation unit having an irradiation opening through which radiation is emitted; an image receiving unit that has an image receiving surface receiving the radiation emitted from the irradiation unit; an arm that has one end at which the irradiation unit is rotatably supported and the other end at which the image receiving unit is supported in a posture in which the irradiation opening and the image receiving surface face each other; a solenoid that locks the rotation of the irradiation unit with respect to the arm in a facing posture in which the irradiation opening and the image receiving surface face each other; and a control unit that permits the moving image capture irradiation in a state in which the rotation of the irradiation unit is locked and prohibits the moving image capture irradiation in a state in which the rotation is unlocked.
