The object of this invention is to provide a radiographic apparatus with an image pickup line movable faithfully to instructions from the operator. That is, according to the construction of this invention, an additional movement controller can carry out feedback control for recurrently controlling movement of an image pickup line. Moreover, the construction of this invention is characterized in that an acceleration acquiring unit acquires an acceleration of the image pickup line. That is, when the velocity of the image pickup line approaches a predetermined velocity, the acceleration of the movable object will be brought close to 0. In this way, overshooting can be inhibited, and the phenomenon of the movable object clattering each time it moves can be prevented reliably, thereby providing an X-ray apparatus excellent in operability.
