Pressure sensitive stylus having resiliently compressible tip element
First Claim
1. In a stylus for use with a digitizer tablet having a working surface, wherein the stylus has a housing, an elongated tip element axially movable in said housing with one end of said tip element extending from said housing and being positioned to be pressed against the working surface of the tablet and the other end of said tip element being positioned within said housing, and a pressure sensitive element positioned within said housing to receive axial pressure from the other end of said tip element resulting from pressure on said one end thereof, the improvement wherein said tip element is resiliently axially compressible.

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.

- 1. In a stylus for use with a digitizer tablet having a working surface, wherein the stylus has a housing, an elongated tip element axially movable in said housing with one end of said tip element extending from said housing and being positioned to be pressed against the working surface of the tablet and the other end of said tip element being positioned within said housing, and a pressure sensitive element positioned within said housing to receive axial pressure from the other end of said tip element resulting from pressure on said one end thereof, the improvement wherein said tip element is resiliently axially compressible.
- 4. A tip element for a stylus comprising first and second axially aligned tip element portions, and means for resiliently coupling said first and second tip element portions, whereby said tip element is axially resiliently compressible.
- 10. A tip element for use in a stylus used with a digitizer tablet, the stylus having a housing and a pressure sensitive element positioned within the housing, the tip element comprising a first end at least a portion of which extends from the housing and is positioned to be pressed against the tablet and a second end positioned within the housing to apply axial pressure to the pressure sensitive element when pressure is applied to the first end, the tip element assuming a first configuration when pressure is not applied to the first end and a second configuration when pressure is applied to the first end, wherein in the second configuration the first end of the tip element is not displaced by the same amount as the second end as compared to the first configuration.
