A battery holder mechanism comprises lower supporting portions for receiving the peripheral edge of a battery holder body from below and upper supporting portions for receiving the same from above when the battery holder body is inserted into a battery inserting opening of a package of an electronic appliance, such as an IC card. The upper and lower supporting portions are provided alternatingly inside an inserting hole of a package.

A battery holder mechanism for holding a battery in an electronic device having a package has a battery holder body adapted to be received in a receiving hole of the package. The battery holder body has a circular-arc portion extending along the circumferential direction of the battery. First and second supporting projection project from the inner peripheral edges of the circular-arc portion and support the battery from both sides. A supporting projecting portion disposed in the package within the receiving hole at a position corresponding to a circumferential interval between the second supporting projection so as to support the battery from the same side as the second supporting projection when the battery holder body is inserted in the battery receiving hole. Engagement pauls resiliently lock the battery holder body within the battery receiving hole. The battery is held by the projections from both sides, so the vertical displacement of the battery can be restricted.

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.

An IC card comprises a module with an electric circuit and two panels adhered to each other to cover the module between them. The two panels are adhered with an adhesive with a sufficient adhesion strength and seals the module with no path of air to the outside of the IC card. Airtight sealing of the IC card in realized in various ways. For example, a groove having a varying width is provided in one of the panels for applying an adhesive, while a groove engaging to the groove is provided in the other of the panels. When the two panels are adhered to each other, gas channels may be formed in the groove at portions with narrower widths, while an adhesive in the groove at portions with wider widths fills the gas channels due to viscosity. In another way, a protrusion provided in one of the panels has an edge opposite to a groove provided in the other of the panels. Thus, the groove is kept air-tight. In a different way, an adhesive having a high viscosity at curing temperature is used. In a still different way, all the space inside the IC card is filled, or a sufficient amount of an adhesive is filled in a space between the two panels around a peripheral thereof. In a further way, the panels are adhered in a thermostat. In a still further way, the panels are adhered with melting at a peripheral thereof.

An IC card includes a substrate having a metal fiber resin material layer made of a mixture of a resin and metal fibers and a conductive pattern. The conductive pattern and the metal fiber resin material layer are electrically insulated from each other by a resist film. Heat radiation and mechanical strength of the IC card are enhanced.

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.

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.
