ABSTRACT:
A "Potter-box" (1) has a holder or Potter-spade (2) provided with dogging means (5, 6) for centering an X-ray film cassette, or some other X-ray radiation receiver, in the direction of an X-axis and a Y-axis. Movement of the holder between a cassette-change position and a film-exposure position and vice versa, is utilized to drive the dogging means (5, 6) directly via a link system, so as to center or decenter the cassette, thereby rendering the provision of separate operating means for effecting centering or decentering of the cassette unnecessary.
