Claims

[Claims for Utility Model Registration] (1) The above-mentioned tablet via the coupling capacitance formed between the detection electrode arranged to slide in the axial direction of the outer cylinder and the coordinate electrode of the tablet. A stylus pen configured to generate a position detection signal representing a coordinate position of and output the position detection signal via a signal amplification circuit disposed at the rear end of the outer cylinder. A stylus pen characterized in that a grounding end disposed at an input stage and a rear end of a distal end member of the outer cylinder facing the detection electrode are directly connected to ground the distal end member. (2) A position detection signal representing the coordinate position of the tablet via the coupling capacitance formed between the detection electrode arranged to slide in the axial direction of the outer cylinder and the coordinate electrode of the tablet. The stylus pen is configured to generate a position detection signal and output the position detection signal via a signal amplification circuit disposed at the rear end of the outer cylinder, the noise suppression capacitor being connected to the input stage of the signal amplification circuit. A stylus pen characterized by being connected in parallel to a position detection signal.
