Abstract: A notebook-type personal computer (hereinafter, personal computer) is provided with electrically conductive contact members, which are connected to a reference electric potential portion of a main body of the personal computer. The contact members are provided within concave portions which are formed at a bottom surface of the personal computer at a location which is separated from a connector. A docking device is provided with an engagement member which is electrically conductive and which is connected to a reference electric potential portion of a main body of the docking device and which can protrude from and withdraw into an opening. The opening is formed at a position which corresponds to the concave portion of the personal computer when the personal computer is completely loaded at the docking device.
