Patent ID: 8842099

Claim:
A touch pen structure, comprising: a conductive main body having a hand-holding portion provided for holding the main body with an electrically conductive cladding portion disposed at an end of the main body, an opening formed on the cladding portion, and a containing space disposed in the main body and interconnected to the opening; a touch element, being a rigid conductor, disposed in the containing space, and having a contact portion formed at an end of the touch element and exposed from the opening, and a limit portion formed at the other end of the touch element and snapped into the opening for positioning; and a conductive elastic element, disposed in the containing space, and having an end abutting the main body, and the other end abutting the limit portion of the touch element, wherein the conductive elastic element enables movement of the touch element with respect to the cladding portion; such that, when being used, the electrically conductive cladding portion and the contact portion cooperatively define a touch area in contact with a touch control surface so as to induce a capacitance change on the touch control surface; and wherein the electrically conductive cladding portion and the contact portion are configured to span a distance substantially equal to the distance between two adjacent electrodes disposed on the touch control surface, such that when the electrically conductive cladding portion and the contact portion are both in contact with the touch control surface, the electrically conductive cladding portion will be in contact with one of the two adjacent electrodes if the contact portion is in contact with the other of the two adjacent electrodes.
