Abstract: An interface device includes a base, a lift mechanism, and a linkage mechanism. The base has a front end, a rear end, left and right sides between the front and rear ends, a top face adapted for placement of a portable computer thereon, a bottom face, and a connector housing. The connector housing is formed at the rear end of the base, and has an upright front wall extending upwardly from the top face of the base. A connector is mounted on the front wall of the connector housing at a predetermined height relative to the top face, and is adapted for engaging a mating connector of the portable computer. The lift mechanism is mounted on the base and is adapted for moving the portable computer upwardly and downwardly relative to the top face of the base so that the mating connector of the portable computer can register with and engage the connector on the base. The linkage mechanism is mounted on the base, and is connected operatively to the lift mechanism in order to actuate the lift mechanism.

Abstract: An externally connected expansion device with replaceable guiding face panel for guiding different portable computers. The expansion device has a guiding seat body in which the guiding face panel is replaceable in accordance with the height from the bases to the connectors of different portable computers. In addition, two sides of the guiding face panel respectively disposed with a stopper member in accordance with the PCMCIA socket and/or MODEM socket of different models of portable computers so as to seal the socket and achieve a protective effect.

Abstract: An externally connected expansion device of portable computer. The expansion device includes an engaging unit and an outward pushing unit. The expansion device has a forward extending seat body disposed with an engaging block. When the portable computer is connected with the expansion device, the engaging block is first lowered and then lifted. After the portable computer is connected with the expansion device, the top section of the engaging block is inserted into an engaging hole formed at rear end of the bottom of the portable computer to engage the portable computer with the expansion device. Two sides of front end of the expansion device are disposed with pushing members drivingly connected with a handle. When it is desired to separate the portable computer from the expansion device, the top section of the engaging block is first sunk into the seat body and then a user can pull the handle to force the pushing members to push the portable computer out of the expansion device.

Abstract: A protection device is disposed between the socket entrance of the expansion socket of the expansion device and the casing of a portable computer. The casing is formed with a window corresponding to the socket entrance. In an unprotected state, the expansion device functions in a normal manner. However, in a protected state, the protection device shields the socket entrance of the expansion socket and prevents an external article from being inserted into or withdrawn from the expansion socket.
