(Embodiment 1)
An example of the ATM installation electromagnetic wave shield device of the present invention is explained based on a drawing. FIG. 1 shows an example in which one electromagnetic wave shield chamber 1 having an ATM installation space and an ATM operation space is elongated and one ATM 2 is installed. The electromagnetic shielding room can also be wide enough to install a plurality of ATMs. The electromagnetic shielding chamber 1 is surrounded by a flooring 3 shown in FIG. 2, a peripheral wall 4 assembled as shown in FIG. 1, and a ceiling 5 above the peripheral wall 4, and an entrance 6 (FIG. 1b) is provided on the peripheral wall 4. The door 7 is attached to the doorway 6. The open / close door 7 may be a door or a sliding door. The electromagnetic wave shielding room 1 can be installed in a necessary place such as in a store such as a financial institution or a convenience store, in a station or airport building, in a public facility building, or outdoors. The electromagnetic wave shielding chamber 1 uses an electromagnetic wave shielding plate or mat (common name: shield mat) for the floor material 3 and an electromagnetic wave shielding glass plate 8 for the peripheral wall 4 and the ceiling 5 to shield the room from electromagnetic waves. The connection part of the material 3 and the peripheral wall 4, the connection part of the peripheral wall 4 and the ceiling 5, and the attachment part of the opening / closing door 7 to the doorway 6 are also made into an electromagnetic wave shield structure. The flooring 3 may be a ground or building floor constructed in an electromagnetic wave shield structure instead of a plate or mat. The electromagnetic shielding may be applied to the electromagnetic shielding structure by laying or burying a conductive mesh or other conductive material on a road surface or floor.
