Title:
ELECTRONIC PEN AND ELECTRONIC PEN MAIN BODY PART
Document Type and Number:
WIPO Patent Application WO/2016/158418
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electronic pen which is capable of responding to both an electromagnetic-induction type position detecting device and a capacitive-coupling type position detecting device. Provided is an electronic pen, comprising: a magnetic body core provided with a through hole and whereupon a coil is wound in a direction in line with the through hole; a conductive center body which is inserted into the through hole of the magnetic body core; capacitors for configuring a resonance circuit together with the coil; a signal generation part which generates a signal, for detecting a position, which is transmitted via the center body; an electricity accumulator part; and a charging circuit which charges the electricity accumulator part by an induced current which is generated in the coil in response to an external magnetic field. The electronic pen is capable of being provided with a state in which the resonance circuit is operating and a state in which the signal is transmitted from the signal generation part via the center body.
