Abstract: A conductive roller is arranged so as to project from an opening of an upper surface of a circuit board unit removably accommodated in a rack. An opening of the rack is covered by a conductive thin plate. When the circuit board unit is accommodated in the rack, the roller fits in the opening of the rack and pushes the conductive thin plate. Thus, the circuit board unit and the rack are brought into electrical contact to perform electromagnetic shielding.
