This relates to an X-ray imaging device that can be changed to a fixed plate 1, and a large-diameter fixed disc 2 at the upper end of the fixed plate 1, with the axes aligned with each other. Fixed shaft 3
is installed vertically, and a rotary sleeve 7, which is fixedly inserted into the intermediate portion of the horizontal arm 6, is mounted and supported on the fixed shaft 3 via a radial bearing 4 and a thrust bearing 5 so as to be horizontally rotatable. , a deceleration device 8' installed on the horizontal arm 6
An X A mounting shaft 13 for rotating the wire film support tube is rotatably inserted through the mounting shaft 13, and the base end of a connecting arm 14 is loosely fitted to the upper end of the mounting shaft 13. A roller 17 is attached to the upper end corner shaft portion 16 of the rotating shaft 15 which is supported in a manner that
The connecting arm 1 is removably fitted into the central square hole 17' of the
4 and a required part of the horizontal arm 6, there is a fixed disk 2 with the outer periphery of the roller 17 fixed to the upper end of the fixed shaft 3.
A tension spring 18 is attached to the outer periphery of the belt 21, and a tension spring 18 is attached to the outer periphery of the belt 21. It is made by suspending the

てＸ線断層写真が撮影される。On the other hand, the rotating shaft 15 at the tip of the connecting arm 14 loosely fitted into the upper end of the mounting rotating shaft 13 that penetrates the tube shaft 12 at one end of the horizontal arm 6 is connected to the square hole 1 of the roller 17 in the upper end corner shaft 16.
7' is fitted and fixed in the rotational direction, and since this roller 17 is pressed against the outer periphery of the fixed disc 2 by the tension spring 18, the rotation of the horizontal arm 6 causes the roller 17 to The rotating shaft 13 rotates along the outer periphery of the fixed disk 2, and the rotating shaft 15 also rotates, so the mounting rotating shaft 13 rotates via the small pulley 19 at the lower end of the rotating shaft 15, the belt 21, and the pulley 20. Due to this rotation, the X-ray film support cylinder 23 connected to the lower end of the mounting rotation shaft 13 rotates with respect to its light receiving surface, and as a result, due to the combination of the rotation of the horizontal arm 6 and the rotation of the mounting rotation shaft 13, A movement trajectory that approximates the dental arch is drawn, and an X-ray tomogram is taken based on this movement trajectory.

点を有する。In the above, when the diameter of the roller 17 is constant, the trajectory of movement drawn will be constant regardless of the age of the subject, the jaw bone structure, etc., and therefore the correct X-ray suitable for the subject will be drawn. Although it has the disadvantage that a tomographic photograph cannot be obtained, in this application, since the roller 17 is removably fitted to the square shaft 16 at the upper end of the rotating shaft 15, it is possible to select and replace the roller 17 with a different shape and size. By doing this, it is possible to easily obtain different movement trajectories, and therefore, by appropriately replacing the roller 17 depending on the age and jaw bone structure of the subject, the roller 17 can be changed to suit the dental arch of the subject. It is extremely convenient to obtain correct X-ray tomograms, and has the advantage that rollers can be easily replaced.
