PURPOSE:To change the feed rate of a roll film of a film camera and to perform X-ray photographing efficiently by projecting the image of an image intensifier on a television camera, controlling the shield area of a stop of a image by means of a control part and outputting the same to the film camera. CONSTITUTION:The X rays from an X-ray source obtained by a stop 2 input a person P to be inspected to an image intensifier (I.I. tube). The image of an output plane 4b is outputted from an image pickup tube 8 via lenses 5, 7 to a television image receiver. An inspector observes the image of a video plane 9a, confirms that the position to be examined and the shield area are adequate, and matches a scale 10 to the value of the dial 22a of a controller 21. A film conveying part 17 is driven under the control of the controller 21 for the input parts 22a, 22b scaled on a film 14 from a mirror 6' by a lens 12, whereby prescribed conveying is accomplished. |
