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 sprocket and chain 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 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 first sprocket connected to the rotation axis of the X-ray tube, a second sprocket connected to a common rotation axis, a third sprocket connected to the rotation axis of the second tray, a fourth sprocket also connected to the common rotation axis, and two chains, one of which chains reverses the rotation direction of the axis connected therewith.
