An X-ray imaging apparatus capable of covering outer peripheral portions of a fixed supporting column and a moving supporting column by a cover even when an SID is set to be large in a configuration in which an imaging system is rotated about an axis extending in a horizontal direction. The supporting column mechanism 17 is provided with a fixed supporting column 34, a moving supporting column 35 movable relative to the fixed supporting column 34, and a moving mechanism for moving the moving supporting column 35. A fixed cover 33 is arranged at the outer peripheral portion of the fixed supporting column 34. Further, at the outer peripheral portion of the moving supporting column 35, a moving cover 31 which moves together with the moving supporting column 35 is arranged. An intermediate cover 32 movable in the same direction as the moving cover 31 is arranged between the fixed cover 33 and the moving cover 31. Between the fixed supporting column 34 and the moving cover 31, a constant force spring 41 as an energizing member for energizing the intermediate cover 32 to the side of the fixed cover 33 is arranged.

An inspection sorting apparatus includes an X-ray tube with an anode electrode and a cathode electrode, a tank housing the X-ray tube and having insulation oil contained therein, and the anode electrode and the cathode electrode are supplied with a predetermined voltage to generate X-ray. An inspection sorting apparatus has an abnormal discharge determination unit, an LCD display, and a notification control unit. The abnormal discharge determination unit individually detects a first abnormal discharge which is an abnormal discharge inside the X-ray tube, and a second abnormal discharge which is an abnormal discharge inside the tank outside the X-ray tube. The LCD display outputs notification information prompting an administrator to replace the X-ray tube or the tank. The notification control unit causes the LCD display to output the notification information in accordance with a detection result from the abnormal discharge determining unit.

A radiation imaging system comprising a radiation imaging apparatus in which pixels are arranged, a radiation source, a display unit, and a controller is provided. The controller causes, during radiation irradiation, the radiation imaging apparatus to repeat a generation operation of generating one image data by causing the pixels to perform an accumulating operation and a readout operation. When it is instructed to terminate the radiation irradiation, the controller causes the radiation source to stop the radiation irradiation in accordance with completion of the accumulating operation and the readout operation of the last row in the generation operation during which it was instructed to terminate the radiation irradiation, and causes the display unit to display an image based on last image data generated by the generation operation during which it was instructed to terminate the radiation irradiation.
