ABSTRACT:
An input pen for use in operating an operating surface of a capacitance-detecting coordinate device includes a rod-like body, a conductive section connected to one end of the body, a conductive ball joint mounted at the tip of the conductive section to turn relative to the conductive section, a conductive operating section integrally joined to the conductive ball joint and projecting from the tip of the conductive section, and a slide switch mounted at the inner tip of the conductive section. The slide switch operates to electrically connect or disconnect the conductive section and the conductive ball joint when the body is pressed toward one end thereof with the conductive operating section in contact with the operating surface.
