Patent ID: 8711130

Claim:
A position pointer, comprising: a substantially tubular housing having an opening at one end; an elongate rod disposed in the housing such that one end thereof projects from the opening of the housing; and a variable capacitor having a capacitance value which varies in response to pressure applied thereto through the rod, the variable capacitor including a dielectric member having a first face portion and a second face portion opposite the first face portion, a first electrode section disposed on the first face portion of the dielectric member, a conductive member disposed facing the second face portion of the dielectric member, the conductive member forming a second electrode section when brought into contact with the second face portion of the dielectric member, wherein a contact area between the conductive member and the second face portion forming the second electrode section varies depending on the pressure applied thereto through the rod, and an elastic member comprising a coil made of conductive material, the elastic member being arranged such that elasticity of the coil biases the conductive member away from the second face portion, and the elastic member being in electrical contact with the conductive member to function as a terminal lead for the conductive member.
