Abstract
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 P2detected by the first pressure sensor becomes greater than pressure P3detected by the second pressure sensor.
