Abstract
A portable computer includes a base unit equipped with a display unit and a keyboard. The base unit has an optional component holding recess covered with an conductive layer for electro-magnetic shielding. An optional component unit is mounted in the holding recess and electrically connected to the base unit. The optional component unit is divided into a printed circuit board having a conductive circuit pattern and a board support for supporting the printed circuit board. The board support is made of an electrically insulating material, such as a synthetic resin material. The opening of the holding recess is closed by a conductive cover. In that closed state, the cover is placed in contact with the conductive layer and, together with the conductive layer, surrounds the optional component unit to achieve an electromagnetic shield.
