Abstract:
To provide a safety cover shielding electromagnetic waves.
A vinyl chloride sheet containing conductive wire cloth is used for the transparent windows 3 of the doors 2 of a safety cover 1 to make the wire cloth and the doors 2 conductive by a conductive material. Furthermore, a conductive rollers are used for the rollers of the doors 2 of the safety cover 1 for conductively processing a rail so that shielding effect on the electromagnetic waves may be added to the transparent windows 3 of the doors 2 for equalizing the potential of the doors 2 of the safety cover 1 with that of the main body, thereby making feasible to shield the electromagnetic waves passing through the safety cover 1.
