ABSTRACT:
An expansion device includes a box-like device body and a second battery pack. The body includes a hard disc drive therein, a fitting recess open to the outer surface of the body, power-receiving terminals provided in the fitting recess and connected to the hard disc drive, and a second connector adapted to be connected to a first connector of a personal computer. The second battery pack is designed to be removably mounted in a battery mount portion, in place of a battery pack of the computer, and includes a coupling portion removably fitted in the fitting portion, the first and second power-supply terminals. When the second battery pack is mounted in the mount portion while the coupling portion is fitted in the fitting recess, the device body is coupled to the computer in a state where the second connector is connected to the first connector and the first and second power-supply terminals contact power-receiving terminals of the computer and the power-receiving terminals of the device body.
