PURPOSE:To simplify the constitution of the titled device and to display a radiation image by simple handling by optically scanning only a radiation-photographed area on a radiation image conversion panel in a radiant ray irradiating area having optional size. CONSTITUTION:An X-ray image conversion panel 52 is charged to a panel holder 34. Subsequently, servo motors 39, 44 controlled by a control device 23 are driven to position the panel holder 34 on a photographing area. Then, X-rays are irradiated from an X-ray tube 28 to a subject 26 and the X-rays transmitted through the subject 26 is absorbed into an accelerated phosphor on an X-ray image conversion panel 52. The photographed X-ray image conversion panel 52 is stored in a take-up magazine 33 and then transferred to a reader 21 and the reader 21 scans the surface of the X-ray image conversion panel 52 optically with laser beams projected from a laser tube 53 on the basis of the rotation of a reflector 54 and the driving of a carrier belt 51. Accelerated light generated by the irradiation of the laser beams is condensed by a condenser part 56, photoelectric converter 57 and then outputted as the data of the X-ray image.
