Abstract
Abstract A door apparatus for a portable computer memory card international association (PCMCIA) aperture formed in a surface of a portable computer having a molded housing structure. The aperture has opposing edges and is configured to receive a PCMCIA card therethrough. The door apparatus includes a first and second doors having inner and outer sides. The outer sides are hingedly coupled via journal members and bearing supports to the opposing edges of the aperture to separately rotate between a closed position wherein the inner sides of the first and second doors are adjacent to one another and an open position wherein the inner sides of the first and second doors are rotated in opposing directions when a PCMCIA card is inserted through the aperture. The door apparatus further includes a biasing member coupled to the first and second doors to thereby pivotally rotate the first and second doors toward the closed position when the PCMCIA card is removed from the aperture. The width of the doors is such that they do not contact a PCMCIA guide/ejector that is positioned adjacent the PCMCIA aperture.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
365 words
A computer comprising: a housing having an exterior wall through which an opening extends into the interior of said housing, said opening being partially bounded by first and second opposing edge portions of said exterior wall and being configured to permit at least one memory card to be inserted therethrough into the interior of said housing; a printed circuit board disposed within the interior of said housing; a guide/ejector structure disposed within the interior of said housing and being operative to releasable receive each inserted memory card and electrically couple it to said printed circuit board; and memory card opening door apparatus including (1) first and second door members each having opposite first and second edge portions, (2) mounting means for securing said first edge portions of said first and second door members to said first and second opposing edge portions of said opening in a manner permitting said first and second door members to be pivoted relative to said exterior wall between a closed position in which said first and second door members are generally parallel to one another and to said exterior wall, with each of said first and second door members blocking approximately half of said opening, and an open position in which said first and second door members are swung inwardly into the interior of said housing, and (2) spring means for resiliently biasing said first and second door members toward said closed position thereof, said mounting means including: spaced first and second pluralities of transverse support plate members integrally formed on inner side portions of said first and second opposing edge portions of said exterior wall and having side edge depressions formed thereon, and spaced first and second pluralities of side edge tab members integrally formed on said first edge portions of said first and second door members, each of said tab members having integrally formed thereon a journal member, said journal members being aligned with and rotatably snapped into said corresponding ones of said side edge depressions of said first and second pluralities of transverse support plate members in a manner permitting said first and second door members to be selectively pivoted between said open and closed positions thereof.
Claim 2
Dependent Claim
