The two pairs of cassette pressing portions 300, 301 each comprise: a mechanism part allowing movement of the two pairs of cassette pressing portions 300, 301 to open or close with respect to a predetermined position 320 in accordance with the center position of the cassette; and pressing parts configured to press the two pairs of cassette pressing portion in the direction in which they are closed. Thus, a cassette can be loaded in the cassette tray easily. Even if the sizes of the cassettes differ, the centers of the cassettes are held in the fixed position, and accordingly, an X-ray radiation area can easily be set according to the size of a loaded cassette. |
