Patent ID: 8576203

Claim:
A cordless type position pointer used together with a capacitance type position detection apparatus for carrying out a position pointing operation, comprising: a housing having electric conductivity; a contacting member having elasticity and electric conductivity and configured to contact the position detection apparatus to point to a position; a core body having a projecting portion provided on one end side thereof to be removably fitted with said contacting member and fixed at the other end side thereof to said housing having electric conductivity, such that a fitting interface between said contacting member and said projecting portion is exposed from said housing in a state in which said contacting member and said projecting portion are fitted with each other; and a sleeve having a through-hole configured such that, when said sleeve is engaged in said position pointer, a distal end portion of said contacting member fitted with said projecting portion is exposed from the sleeve and at least a portion of the fitting interface is enclosed in the sleeve; wherein the through-hole of the sleeve is formed in a tapering shape such that a diameter of the through-hole generally increases from a distal end side toward a proximal end side, to ensure a secure fitting between said contacting member and the projecting portion of the core body and to suppress displacement of the contacting member when the sleeve is engaged in said position pointer, and wherein said contacting member and said projecting portion are fitted with each other such that one of said contacting member and said projecting portion covers the other of said contacting member and said projecting portion, in a fitting relationship wherein said one includes a projection and said other includes a groove corresponding to said projection, and said contacting member is electrically engaged with said housing through at least one of said core body and said sleeve.
