真撮影装置。[Scope of claim for utility model registration] 1. A head fixing device that fixes the subject's head in a specified position, and an X that maintains a constant relative distance to the head.
The imaging system, which consists of a radiation source and a cassette telegraph device, is rotated about the vertical line at the point where the reference line connecting both external auditory canals of the patient intersects the midsagittal plane, and the patient's head and imaging system are relative to each other. In the device, the device is equipped with a rotating mechanism that rotates by a predetermined angle and positions the front and side photographing positions respectively, and is configured to switchably take standard photographs of the front side. A film that corresponds to the positioning of the rotating mechanism and that uses the frontal imaging position of the X-ray film as a reference point and switches the side imaging position parallel to the midsagittal plane of the subject and moves it a predetermined distance in the direction of the patient's face. A cranial X-ray standard photography device characterized by being provided with a position reversible correction mechanism. 2. The cranial X-ray standard photographing device according to claim 1, wherein the film position reversible correction mechanism has an additional function of correcting the 45° oblique photographing position.
