摘要: A pressure-sensitive, conductive elastic sheet for use in a graphics digitizing tablet through which various letters or figures can be detected, the characteristics of are such that contact pressure is almost constant irrespective area increases with increasing area. The pressure-sensitive according to present invention comprises silicon rubber number coarse, ferromagnetic, metal particles diameter 30 150 micron mixed fine, 10 less 50 at predetermined proportion manner coarse aligned vertically interior thereof and fine dispersed near least one surface thereof. To properly align particles, allowed set within uniform magnetic field.
