SOLUTION: A floor surface consists of a metal plate 6, and a space for a photographic apparatus is surrounded by a metal mesh 1 supported by supporting pillars 2a to 2d and connected with a noise filter 3. Thus, the space for the photographic apparatus is shielded from electromagnetic noise, or the like. Thus, it is not required to give the RF shield to the whole operation room, influence of the line noise from another apparatus is removed, the electromagnetic shield body is inexpensive and installed easily.
