Abstract

According to one embodiment, an electronic apparatus includes: a first casing provided with a metal part, a pointing device and a circuit board, the pointing device being mounted on the circuit board, the circuit board being provided with a cover member for covering the pointing device; a second casing being joined to the first casing and having a hole made so as to expose a part of the cover member; a conductor being provided at a position opposed to a gap existing between the cover member and the second casing in the circuit board; and a conductive member for electrically connecting the conductor and the metal part.

Claims

1. An electronic apparatus comprising:

a circuit board;

a pointing device mounted on the circuit board;

a cover member for covering the pointing device;

a first casing provided with a metal part, in which the circuit board is disposed;

a second casing joined to the first casing and having a hole that allows a part of the cover member to be exposed outside;

a conductor provided in the circuit board at a position opposed to a gap between the cover member and the second casing; and

a conductive member for electrically connecting the conductor and the metal part.

2. The apparatus according to claim 1, wherein the conductor includes a piercing member piercing the circuit board in a thickness direction thereof.

3. The apparatus according to claim 2, wherein:

the ground member includes a first ground member provided on an upper face of the circuit board and a second ground member provided on an lower face of the circuit board; and

the second ground member and the conductive member are electrically connected.

4. The apparatus according to claim 2, wherein the cover member is mounted on the circuit board and the conductor is provided at a position out of the cover member on the circuit board.

5. The apparatus according to claim 3, wherein an entire of the second casing or at least a portion around the hole of the second casing is formed of a resin.
