X-ray image recording device

Claim 1

In an X-ray image recording device, comprising image storage means for storing X-ray shadow images, a read-out station for reading out the images stored in the image storage means, and an erasing station for erasing residual images present in the image storage means, the improvement, comprising: a prismatic body having at least three sides surfaces, which carries the image storage means on said side surfaces and which can be rotated to present said side surfaces at at least three different positions about a first axis of rotation, said first axis being symmetrically situated with respect to said side surfaces; at least three planar two-sided plates, the image storage means being disposed on both sides of each of said plates, each of the plates being impermeable to light and to X-rays, disposed on a corresponding side surface of the prismatic body, and rotatable through 180° about a second axis which is parallel to the plane of the plate so that in a first position of each plate a first side thereof is directed toward the interior of the body and in a second position thereof the second side is directed toward the interior of the body; wherein the erasing station comprises illuminating means disposed within the body; the sides of the body define apertures which expose the inwardly directed side of at least one plate to the illuminating means; and the body, an image storage means, the read-out station, and the erasing station being arranged so that when the body is rotated to the various positions about the first axis, image storage means cyclically and successively enter the storage means, the read-out station, and the erasing station.
