Abstract

PURPOSE:To obtain an X-ray photograph of superior image quality by giving prescribed bending rigidity to the front plate and back plate of a device which press-contacts a photographic film through pressing part of the back surface of the back plate. CONSTITUTION:In this press-contacting device, the contactness of such all layers as a front plate 1 and a cushion material 6 which cover an X-ray photographic film 3 by partially pressing the back surfaces of back plates 7 and 8 is improved. Then, EI(f)Xt>=8.0X10<7>kg.mm.<3> and EI(b)Xt>=3.0X 10<7>kg.mm.<3>, where EI(f) is the flexural rigidity of the front plate 1, EI(b) is the flexural rigidity of the back plates 7 and 8, and (t) is the thickness of the cushion material 6. Consequently, an X-ray photographic film 3 is pressed uniformly to improve its contactness over the entire surface, thus obtaining an X-ray image of superior quality.
