Abstract
The X-ray apparatus contains an X-ray tube and a transition device for moving the X-ray tube between a vertical and a horizontal emission position. A first film cassette tray may be provided for vertical exposures. A second film cassette tray is provided for horizontal exposures. The X-ray apparatus further contains a mechanism for operationally connecting the second tray to the X-ray tube. This mechanism is designed such that the second tray is positioned in a waiting position outside the vertical X-ray beam when the X-ray tube is in its vertical emission position and such that the second tray is automatically transferred from the waiting position to a horizontal exposure position when the X-ray tube is moved from its vertical emission position to its horizontal emission position. The mechanism preferably contains a large number of arms and levers.
