Abstract:
A pen-shaped position indicator includes: i) a cylindrical housing; ii) a core received in the cylindrical housing and having a pointer tip extend from a distal end of the cylindrical housing; iii) a resonant circuit comprised of an inductive element and a capacitor and received in the cylindrical housing, wherein an inductance of the inductive element changes in response to a pressure applied to the pointer tip of the core; iv) a connection member received in the cylindrical housing between the inductive element and the capacitor, wherein the connection member includes a distal surface facing the inductive element and a proximal surface facing the capacitor, and the connection member includes a terminal member having a distal end and a proximal end; and v) a first conductor disposed on a distal surface of the capacitor facing the proximal surface of the connection member, wherein the first conductor electrically connects the capacitor, via the at least one terminal of the connection member, to the inductive element.
