Abstract
A stylus for use with a digitizer tablet has a tip element that includes a front portion with a tip for engaging the surface of the tablet, and a back portion of the tip element within the stylus housing. The back portion of the tip element is adapted to apply pressure to a pressure sensitive resistance element. The front and back portions of the tip element are coupled together by a spring, in order that the tip element be resiliently compressible in the axial direction of the stylus.
