[Industrial applications]

 The present invention relates to a memory card in which at least one surface of a memory card having an IC memory and an external terminal connected to the IC memory is covered with a conductive panel having a non-conductive coating formed on the outer surface thereof, and particularly, a conductive memory card is provided. The present invention relates to a memory card capable of confirming whether or not the panel is electrically connected to the ground terminal of the external terminal even after the conductive panel is attached.

[Prior art and its problems]

 Conventionally, as shown in a perspective view in FIG. 3 and a cross-sectional view in FIG. 4, both sides of a memory card 1 having an IC memory 11 and a large number of external terminals 12 connected to the IC memory 11 are provided on the outer surface. There is known a memory card 1 which is covered with two conductive panels 2 having a conductive coating film 21 formed thereon. In this case, the two conductive panels 2 and 2 are electrically connected to each other by the printed wiring 4 connected to the ground terminal of the external terminal 12 through the metal spring members 3 and 3. As a result, the two conductive panels 2 and 2 are electrically connected to the ground terminal of the external terminal 12, so that even if static electricity is negatively applied to the memory card 1, the static electricity is generated in the conductive panels 2 and 2. From the external terminal 12 to the external device through the ground terminal, it is possible to prevent the IC memory built in the memory card 1 from being electrostatically destroyed.

However, in the related art, since the non-conductive coating film 21 is formed on the outer surfaces of the conductive panels 2 and 2, after the conductive panels 2 and 2 are attached, the conductive panels 2 and 2 are external. There was a problem that it was not possible to confirm whether or not the terminal 12 was connected to the ground terminal portion.

[Means for Solving the Problems]

 The present invention is to solve the above-mentioned problems, and its gist is to provide a non-conductive coating on at least one surface of a memory card having an IC memory and an external terminal connected to the IC memory. In a memory card covered with a conductive panel, the inner surface of the conductive panel is electrically connected to the ground terminal of the external terminal, and a part of the non-conductive coating formed on the outer surface of the conductive panel. By forming a notch on the exposed side of the conductive panel, it is possible to check whether the conductive panel is connected to the ground terminal of the external terminal even after the conductive panel is attached. It is a memory card.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing a memory card of the present invention, and FIG. 2 is a sectional view showing a main part of a memory card of the present invention. In FIG. 1, reference numeral 1 denotes a memory card, which has an IC memory 11 and a large number of external terminals 12 connected to the IC memory 11, and both surfaces of the memory card 1 are formed with a non-conductive film 21 on the outer surface. The memory card 1 is constructed by being covered with two conductive panels 2.

As shown in the sectional view of FIG. 2, the two conductive panels 2 and 2 are connected by a printed wiring 4 which is connected to the ground terminal of the external terminal 12 through metal spring members 3 and 3. Since the two electrically conductive panels 2 and 2 are electrically connected to each other and electrically connected to the ground terminal of the external terminal 12, even if static electricity is negatively applied to the memory card 1, the static electricity is conductive. As it flows from the panels 2 and 2 to the external device through the ground terminal of the external terminal 12, it is possible to prevent the IC memory 11 built in the memory card 1 from being electrostatically damaged. The invention is characterized in that the notch 5 is formed in a part of the non-conductive film 21 formed on the outer side surfaces of the conductive panels 2 and 2 to expose the conductive panel 2. In this way, the notch 5 formed in a part of the non-conductive film 21 and the ground terminal of the external terminal 12 are brought into contact with the terminals of the tester, so that the conductive panels 2 and 2 can be easily grounded to the ground of the external terminal 12. You can check whether it is connected to the terminal.

The present invention is not limited to the memory card 1 having two conductive panels 2 and 2, but only one surface of the memory card 1 is covered with the conductive panel 2 having the non-conductive coating 21 formed on the outer surface. Of course, it can also be applied to a memory card.

[Effect of device]

 As described above, according to the present invention, a memory card in which at least one side of a memory card having an IC memory and an external terminal connected to the IC memory is covered with a conductive panel having a non-conductive coating formed on the outer surface. In the card, the inner surface of the conductive panel was electrically connected to the ground terminal of the external terminal, and a cutout was formed in a part of the non-conductive film formed on the outer surface of the conductive panel. Even after mounting the conductive panel, there is an advantage that you can check whether the conductive panel is connected to the ground terminal of the external terminal.
