Touch keyboard with keys

Abstract

A touch keyboard includes a support plate, multiple elastomers, multiple keycaps, multiple linkage members, and a capacitive touchpad. The elastomers are disposed on the support plate in a manner protrudes from the top surface of the support plate. The keycaps are mounted on the top ends of the elastomers. The linkage members are positioned between the support plate and the keycaps. The capacitive touchpad is attached to the bottom surface of the support plate for sensing a location and movement trajectory of a conductive object (such as a finger) approaching the keycaps. Thus, the touch keyboard of the present invention places the capacitive touchpad beneath the support plate, which reduces or even eliminates the need for through holes in the capacitive touchpad, thereby minimizing touch dead zones and enhancing touch accuracy.
