Abstract

A portable storage device that is connected to an external device to receive and output a signal, has a cover case that has an opening in a front surface thereof and a slit penetrating a wall thereof, a potential of the inner surface of the cover case being kept at the ground potential by connecting to the external device; a circuit board held in said cover case; a connector terminal for connection to said external device that is connected to a front part of said circuit board and disposed to be exposed through the opening of said cover case; a semiconductor memory for storing data that is mounted on said circuit board and connected to said connector terminal; and a controller mounted on said circuit board for controlling said semiconductor memory.

Claims

1. A portable storage device that is connected to an external device to receive and output a signal, comprising:

a cover case that has an opening in a front surface thereof and a slit penetrating a wall thereof, a potential of the inner surface of the cover case being kept at the ground potential by connecting to the external device;

a circuit board held in said cover case;

a connector terminal for connection to said external device that is connected to a front part of said circuit board and disposed to be exposed through the opening of said cover case;

a semiconductor memory for storing data that is mounted on said circuit board and connected to said connector terminal; and

a controller mounted on said circuit board for controlling said semiconductor memory.

2. The portable storage device according to claim 1, wherein a conductive coating is formed on the inner surface of said cover case and is connected to the ground potential.

3. The portable storage device according to claim 2, wherein said cover case has a conductive shielding plate for preventing electro-static discharge between said slit and said semiconductor memory or said controller.

4. The portable storage device according to claim 3, wherein said cover case has a heat dissipation plate having a slit attached to at least a part of the wall thereof.

5. The portable storage device according to claim 4, wherein said conductive coating is connected to said connector terminal or a grounding wire on said circuit board.

6. The portable storage device according to claim 1, wherein said cover case has a conductive shielding plate for preventing electro-static discharge between said slit and said semiconductor memory or said controller.

7. The portable storage device according to claim 1, wherein said cover case has a heat dissipation plate having a slit attached to at least a part of the wall thereof.

8. The portable storage device according to claim 2, wherein said conductive coating is connected to said connector terminal or a grounding wire on said circuit board.

9. The portable storage device according to claim 3, wherein said conductive coating is connected to said connector terminal or a grounding wire on said circuit board.

10. The portable storage device according to claim 1, wherein the cover case is made of a conductive material.

11. The portable storage device according to claim 2, wherein the cover case is made of a non-conductive resin.
