Abstract:
1. A data processing terminal comprising: a first board including a first circuit; a second board disposed substantially in parallel with said first board and including a second circuit; a first ground plane disposed on said first board, and comprised of a conductor in a predetermined shape for determining a potential reference for said first board; a second ground plane disposed on said second board, and comprised of a conductor in a predetermined shape for determining a potential reference for said second board; a ground terminal for connecting a position near one end of an edge of said second ground plane to said first ground plane; a signal terminal for communicating an electric signal between said first circuit and said second circuit; a connector including said ground terminal and said signal terminal; and resistive connecting means for connecting a position near one end of the other edge of said second ground plane to said first ground plane, and having a predetermined resistance value R which satisfies: where w represents a length of an edge of said second ground plane near which said resistive connecting means is positioned, h represents a spacing between said first ground plane and said second ground plane, and α1 and α2 are predetermined coefficients which satisfy α1≦1<α2.
