ABSTRACT:
This disclosure relates to an X-ray photographing apparatus both for photographing the entire jaws and for cephalographic use. The apparatus is constructed in such a manner that, in setting the generator in any direction either for cephalographic use or for use in photographing the entire jaws, the X-ray generator is automatically vertically rotated through a specified angle and is enabled to make simple and correct change in the direction of irradiation by providing the X-ray generator mounted horizontally and vertically rotatably at one end of a rotary arm with a sliding element, providing the arm with an inclined guide groove for guiding the element therein, and merely rotating the generator horizontally through a specified angle.
