  • Patent number: 5661636
    Abstract: An IC card with an on-board hard disk unit comprising a frame; a circuit board inside the frame; and a hard disk unit mounted on the circuit board. The IC card also has a metal front panel supported by the frame, and covering the entire IC card, including the hard disk unit. Thus, the outer surface of the IC card is made stronger, and the hard disk is protected from static electricity. The metal front panel includes a first portion where the IC card is relatively thin and a second, bulging portion where the IC card is relatively thick. The bulging portion accommodates the hard disk unit. The front panel may include a vent or mesh.

  • Patent number: 5327010
    Abstract: An IC card includes a substrate, semiconductor devices mounted on at least one of the major surfaces of the substrate and a casing in which the substrate with the semiconductor devices mounted on it is housed. The casing includes a frame and panels bonded to the frame on the opposite sides of the frame by means of adhesive layers. The semiconductor devices are prevented from being bonded to the panel via the adhesive layers at locations on the adhesive layers facing the semiconductor devices.

  • Patent number: 5313364
    Abstract: An IC card arranged so that a connector cannot come off a frame during an assembly process in which the connector and a circuit board are accommodated in the frame and panels are thereafter attached to obverse and reverse surfaces of the frame. Projections on sides of the connector and resilient engaging/fixing hooks with oblique surfaces on the frame are engaged. As the connector is forced into the frame, the projections of the connector are brought into engagement with and temporarily deflect the engaging/fixing hooks of the frame. The connector is thereby fixed firmly on the frame.

  • Patent number: 5299940
    Abstract: An IC card is disclosed which would not be deformed, and hence, which maintains its quality reliability. A frame is provided to house a substrate which mounts ICs. Panels for protecting the ICs are fixed to the frame by first adhesive material layers. A connector is disposed, in contact with the substrate, between the panels. The connector is fixed to the frame by a second adhesive material layer. This prohibits that external force which acts on the connector at insertion and detachment of the IC card into and from external equipment from acting on the first adhesive material layers. Hence, insertion and detachment of the IC card do not cause deterioration in adhesion between the panels and the frame. Thus, deformation of the ICs due to the external force is prevented, thereby the quality reliability of the IC card being better maintained.

  • Patent number: 5173841
    Abstract: A semiconductor device card and a method of manufacturing the card. A frame includes an integral spacer which fills a dead space on a circuit board to eliminate the need for positioning a separate spacer in the dead space on the circuit board and fixing the spacer in place with a bonding sheet or the like. In a semiconductor device card in which a spacer for filling a dead space on the circuit board is bonded to a corresponding panel, a recess is formed on the surface of the spacer bonded to the obverse or reverse panel to reduce undulations occurring in the panel surface.

  • Patent number: 5038250
    Abstract: An IC card of the present invention comprises a panel having resilient projections and a frame having recesses corresponding to the resilient projections, and the panel is mounted on the frame by engaging the respective resilient projections with the respective recesses. Thus, the panel can be securely attached to the panel.
