Abstract

A touch pad structure includes a first casing, a second casing, a touch pad, an elastic element, a button, and an adjusting element. The first casing has an opening and is disposed on the second casing. The touch pad is disposed in the opening. The touch pad has a pivot portion and a movable portion. The pivot portion is pivoted to the first casing. A side of the movable portion facing the second casing is provided with a trigger. The elastic element is located between the first casing and the second casing. The elastic element has a first end and a second end. The button is aligned to the trigger and abuts against the first end of the elastic element. The adjusting element rotatably and movably penetrates through the second casing and is aligned to the button. The adjusting element abuts against the second end of the elastic element.

First claim

What is claimed is:
