Electronic apparatus

1. An electronic apparatus comprising:

a housing comprising a top wall;

a keyboard supported on the top wall; and

a touchpad contained in the housing along an inner surface of the top wall, wherein

the top wall comprises a region positioned on the front side of the keyboard, the region comprising a touchpad surface covering the touchpad so that the touchpad is hidden from an outside of the housing, and a palm-rest surface situated off the touchpad surface, and on which a user's hand is to be placed,

the touchpad surface and the palm-rest surface are positioned on the same plane as a part of the top wall, and

the palm-rest surface is rough in texture as compared with the touchpad surface, and the rough palm-rest surface is immediately adjacent to the touchpad surface and surrounds the touchpad surface so that an outline of an area where the touchpad is capable of receiving input can be recognized by hand.

2. The electronic apparatus of claim 1 , wherein the palm-rest surface is provided with protrusions arranged at regular intervals to form a rough texture.

3. The electronic apparatus of claim 1 , wherein the touchpad surface is shifted from a center portion of the housing, and a keyboard centerline which passes through between an F key and a J key of the keyboard passes through a center portion of the touchpad surface.

4. An electronic apparatus comprising:

a housing comprising a top wall, the top wall comprises a touchpad surface and a palm-rest surface; and

a touchpad contained in the housing along an inner surface of the top wall at least partially under the touchpad surface so that the touchpad is hidden from an outside of the housing, wherein

the touchpad surface and the palm-rest surface are planar forming a part of the top wall, and

the palm-rest surface is different in texture than the touchpad surface, and the palm-rest surface is immediately adjacent to the touchpad surface and surrounds the touchpad surface so that a border between areas where the touchpad is capable and incapable of receiving input can be recognized by hand.

5. The electronic apparatus of claim 4 further comprising a keyboard supported on the top wall of the housing.

6. The electronic apparatus of claim 5 , wherein the palm-rest surface is provided with protrusions arranged to form a texture rougher than a texture of the touchpad surface.

7. The electronic apparatus of claim 5 , wherein the palm-rest surface is provided with protrusions arranged at regular intervals to form a texture rougher than a texture of the touchpad surface.

8. The electronic apparatus of claim 5 , wherein the palm-rest surface is provided with convex protrusions arranged at regular intervals to form a rough texture different than a texture of the touchpad surface.

9. The electronic apparatus of claim 5 , wherein the touchpad surface is shifted from a center portion of the housing, and a keyboard centerline passing between an F key and a J key of the keyboard passes through a center portion of the touchpad surface.

10. The electronic apparatus of claim 1 , wherein the palm-rest surface extends from a region adjacent to the touchpad surface to a region in a vicinity of an end of the housing, the palm-rest surface forming a uniform surface of the housing between the touchpad surface and the end of the housing.

11. The electronic apparatus of claim 4 , wherein the palm-rest surface extends from a region adjacent to the touchpad surface to a region in a vicinity of an end of the housing, the palm-rest surface forming a uniform surface of the housing between the touchpad surface and the end of the housing.
