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. Because the contact members and the engagement member are provided at positions spaced apart from the connector, the electric potential difference between the personal computer and the docking device can be eliminated.
