摘要:
There is provided an IC card where a pair of, upper and lower metal panels are respectively fixed to the frame; edge portions of the metal panel are provided with bend portions; grooves each of which comprises a pair of uneven vertical walls having a plurality of depressions and projections extending in the direction of the width of the frame are provided on the top and bottom surfaces of the frame; the distance between the projections on both the uneven vertical walls in the direction of the width of the frame is set so as to be smaller than the thickness of the bend portions by a given amount; and the metal panel is fixed to the frame with the bend portions press-fitted into the grooves along the projections. The IC card is advantageous in the manufacturing cost and is capable of stably providing a fixing force sufficient to withstand a long-term use, with regard to the fixation of upper and lower panel members to a frame.

An IC memory card has a connector that cannot warp during the manufacturing process even if the connector is long, such as a connector at one longer side of the IC memory card with an increased number of poles. The IC memory card has grooves in the surfaces of a flange portion of the connector body opposing a surface with which the connection with an external unit is established, the grooves being adjacent the connector body and extending lengthwise along all of the longer side of the IC memory card for preventing warping.
摘要:
An IC card having a circuit board provided with wiring formed on at least one of two surfaces of the circuit board, a terminal base fixed to one surface of a front portion of the circuit board and having a multiplicity of electrode terminals disposed on its upper surface, a plurality of electronic parts mounted on the two surfaces of the circuit board, and a package in which the circuit board on which the electronic parts are mounted is incorporated while exposing the electrode terminals to the outside of the package.
摘要:
A mechanism for connecting an IC card and an external device to each other, having: a plurality of electrode terminals formed on a package of the IC card incorporating a semiconductor device and used to connect the semiconductor device to the external device; at least one engagement recess and/or engagement projection formed on the package of the IC card; and a connector provided in the external device. This connector is provided with an insertion hole, a plurality of electrode-contacting pieces disposed in the insertion hole and capable of contacting the plurality of electrode terminals of the IC card when the IC card is inserted into the connector, and at least one engagement projection and/or engagement recess formed inside the insertion hole and capable of engaging the engagement recess and/or engagement projection formed on the package to enable a particular type of the IC card to be inserted into the connector.
摘要:
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.
摘要:
An IC card has a card body with a plurality of slits extending through the thickness card body and a pair of metallic panels secured to the card body. The metallic panels have engaging portions which extend into the slits when the metallic panels are secured to the card body so that the engaging portions of both panels engage each other within respective slits to fasten both metallic panels to the card body. The electrical potentials of both metallic panels are equalized through these engaging portions.
摘要:
An IC card having a shutter, in which the right and left sides of the shutter are bent to form L-shaped flanges enclosing the sides of an electrode terminal board, the shutter sliding over the electrode terminal board.
摘要:
A connection mechanism for connecting an IC card and an external device to each other, having: a plurality of electrode terminals formed on the IC card package in which a semiconductor device is incorporated, the electrode terminals being adapted to connect the semiconductor device to the external device; a pair of engagement recesses formed on the package of the IC card; and a connector provided in the external device, the connector having a card receiving portion into which the IC card is inserted, a plurality of electrode-contacting pieces disposed inside the card receiving portion and capable of contacting the plurality of electrode terminals of the IC card when the IC card is inserted into the card receiving portion to a predetermined position, and a pair of retaining members disposed on the card receiving portion and capable of advancing toward or retreating from the engagement recesses of the IC card and resiliently engaging the engagement recesses so as to retain the IC card at the predetermined position when the IC card is inserted to the predetermined position.
摘要:
An IC card, and manufacturing method thereof, are provided in which a pair of upper and lower metal panels are fixed to the top and bottom surfaces of a resin frame. Projections projecting upward or downward and having a given height are formed at a given distance from the outside edges of the frame. Cut-outs capable of fitting on the projections are provided on the metal panels, and the metal panels are assembled on the top and bottom surfaces of the frame with the cut-outs fitted on the corresponding projections. A portion of each projection is then deformed by pressing on the metal panels from above or below under a predetermined condition so that the metal panels are riveted to the frame.
摘要:
An IC card (1) has a shape of a substantially flat rectangular parallelepiped. The IC card (1) has electronic devices (2) including integrated circuits, a substrate (3) and a frame (5) for supporting the electronic devices (2), a first panel (6c) covering the upper surface of the frame (5), and a second panel (6d) covering the lower surface of the frame (5). Hereupon, the first panel (6c) is directly mounted to the frame (5) in such a manner that each of the left and right end portions (15) of the first panel (6c) is bent twice in accordance with the outer surface of the frame (5) and further each of edges of the left and right end portions (15) is fastened to the lower surface of the frame (5).
