POINTING DEVICE FOR A PORTABLE COMPUTER

摘要

A pointing device for a portable computer is disclosed. The pointing device includes an operation cover for covering a first and second pressure sensors. The pointing device also includes one front operation surface and two rear pressure faces. Detection axes are arranged in a vertical direction, and the pressure faces are so inclined that normal lines will approach each other above the operation surface. The operation surface is applied with depression pressure P1 including a horizontal component Ph and a vertical component Pv. Even when any position on the operation surface is pressed down, pressure P2a detected by the first pressure sensor becomes greater than pressure P3a detected by the second pressure sensor.

主权项

1. A pointing device comprising:
a plurality of pressure sensors, each having a detection axis and arranged in a radial manner about an original point; an operation surface operated by applying depression pressure including a horizontal component and a vertical component; and a plurality of pressure faces, each of which is arranged to correspond to each pressure sensor and displaced according to said horizontal component of said depression pressure applied to said original point, so that each pressure sensor is applied with different pressure according to a direction and magnitude of said horizontal component.
