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.

Abstract: A card holding apparatus of the present invention includes a seal member 12 that is provided so as to surround the periphery of a contact terminal portion 11. When a lid 3 is positioned in a closed position with a smart card 100 retained by the lid 3, the seal member 12 comes into close contact with the periphery of a terminal 101. Thus, even when foreign matter such as water or dust intrudes into a space between the lid 3 and a housing 1, adhesion of such foreign matter to contact terminals 11a or the terminal 101 can be prevented.

Abstract: Electronic equipment according to the present invention can be attached removably to another device with screws 5a and 5b. The equipment includes: a housing 1; a through hole 4d that is formed in the housing 1 and in which each of the screws 5a and 5b is inserted and supported; and a bush 21 that can be attached removably to a head 5c of each of the screws 5a and 5b that is inserted and supported in the through hole 4d. The bush 21 includes a through hole 21 into which the head 5c of each of the screws 5a and 5b can be pressed and mounted. At least a part of the bush 21 is in contact with the housing 1 when the head 5c of each of the screws 5a and 5b is pressed and mounted into the bush 21. Thus, it is possible to provide electronic equipment in which screws are less likely to come loose even when subjected to a disturbance such as vibrations.

Abstract: In the cover opening and dosing device of the present invention, a terminal cover 21 includes a turn regulating portion 24. The turn regulating portion 24 can prevent the terminal cover 21 from turning in a cover dosing direction due to resilience of coupling portions 22 and 23 when the terminal cover 21 is moved to a cover opening position. Thus, when connecting a cable to a terminal, the terminal cover 21 does not hinder the connection, so that the cable can be connected to the terminal with ease. It is possible to achieve a configuration of holding the terminal cover capable of opening and dosing the terminal open with ease and at low cost.
