  • Publication number: 20020005490
    Abstract: There is provided a radiographic apparatus or a digital cassette in which a metal support is fitted to the interior of a casing of the apparatus through spacers, an x-ray image detection panel is disposed on a front surface of the support, an electric circuit board is fixed to a back surface of the support through projections and the x-ray image detection panel and the electric circuit board are connected to each other by flexible circuit boards. Because shock absorbers made of sheet-like elastic material or gel material are disposed on the inner side of the side walls of the casing, even if the apparatus drops down from its side wall by mistake and the side wall of the casing is instantaneously deformed, the shock is absorbed by the shock absorber, thereby the shock transmiting to the support, the x-ray image detection panel, the flexible circuit board or the like can be reduced. As a result, the shock resistance of the apparatus is improved.
