Abstract
A portable computer 1 has a first metallic portion 6 and a second metallic portion 7, and an expansion device 10 has a first magnet 16 and a second magnet 17, whereby the expansion device 10 can be attached to a predetermined position of the portable computer 1 using attractive forces generated by the magnets. Therefore, when the portable computer 1 to which the expansion device 10 is attached is dropped mistakenly on a floor, etc., and the impact is applied on the expansion device 10, the expansion device 10 is separated from the portable computer 1 easily. Thus, even if the expansion device 10 is damaged, the impact to be transmitted to the portable computer 1 can be reduced by separating the expansion device 10 from the portable computer 1, which reduces damage to the portable computer 1.
