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.
Claims4
A radiographic apparatus having an X-ray generator horizontally and vertically rotatably mounted at one end of a rotary arm and designed to set the generator in any direction of irradiation either for cephalographic use or for use in photographing the entire jaws, said apparatus being characterized in that said generator is provided with a sliding element and a guide groove for said sliding element in said rotary arm, said groove being inclined to guide said sliding element to make automatic vertical rotation of said X-ray generator through a specified angle for changing the direction of the generator from one state of the generator set either for cephalographic use or for use in photographing the entire jaws to the other state thereof set for photographing.
