摘要 <p>PROBLEM TO BE SOLVED: To grasp a shape of a packed object such as a parcel or the like in one inspection, by setting a relative position and a direction of a pair of an X-ray source and an L-shaped X-ray detector so that X rays are projected and detected from different directions with different angles to the object to be inspected on a transfer device. SOLUTION: A relative position and a direction of X-ray sources and L- shaped X-ray detectors (1a, 6a, 1b, 6b) are set so that X rays are projected and inspected from different directions with different angles to a parcel 4 on a belt conveyor 5. The parcel 4 is moved between the X-ray source and the confronting L-shaped X-ray detector 6a. An X-ray flux 2a emitted from the X-ray source 1a penetrates the parcel 4 and is converted to an electric signal. The parcel 4 is further moved between the X-ray source 1b and the confronting L-shaped detector 6b. An X-ray flux 2b from the X-ray source 1b passes the parcel 4 and is converted to an electric signal. The parcel 4 can be surely inspected at television monitors 9a, 9b without being changed in direction with the use of data stored in an image-processing device 24.</p>
