PURPOSE:To bring sensitizing paper into close contact with an X-ray film over the whole face, and to prevent the yellow change deterioration of a fluorescent coating film of the sensitizing paper, by providing a pair of magnetic attracting members on the first paper and the second paper. CONSTITUTION:A substrate 4 is rotated in the direction A against a spring steel rod 8 and an X-ray film is placed on the first sensitizing paper 3. Subsequently, the substrate 4 is rotated in the direction B, and the film 12 is placed between the paper 3 and the second sensitizing paper 7. When an electric power source is turned on, a coillike pattern of a sheet coil 13 is electrically conducted, a magnetic field is generated and a metallic foil 14 is attracted by magnetic force. Accordingly, the film placed between the coil 13 and the foil 14 is adhered closely and is held between the paper 3 and the paper 7. A pattern of the coil is formed by photoetching, and can be set uniformly over the whole face of the film 12. In this case, force of the spring steel rod 8 operates as only auxiliary pressure. Even if the foil 14 exists, it does not occur that the transmittance is deteriorated remarkably when X-rays are made incident as indicated with an arrow C. |
