Abstract
PURPOSE: To miniaturize the device and improve the picture image resolution, by using a first shielding body which may be moved in a specified direction and a second shielding body with a slit which is rotatable.
CONSTITUTION: A grid 11 having convex and concave slit 12 is rotatably incorporated into a shutter 7 which is capable of moving in the vertical direction. In this state, the film 1 is completely shielded from the X-ray passing through the object being inspected 4 by the upper part of the shutter 7. When the shutter 7 is moved upwards, the grid 11 rotates in cooperation, directing its slit towards the focal direction of an X-ray generation apparatus 5, so that the X-ray may be passed through the object being inspected 4 and slit 12 to be radiated on the film 1, thereby performing continuous radiography. In this constitution, since the grid 11 is incorporated into the shutter 7, the device is miniaturized. At the same time, since the spacing between the film 1 and the object being inspected 4 is shortened, the resolution of picture image may be enhanced.
