Electronic pen of capacitive system, electronic pen cartridge of capacitive system, charging tray for electronic pen, and charging tray for electronic pen cartridge

Abstract

An electronic pen of a capacitive system includes a tubular pen casing, which houses an electronic circuit including a signal transmitting circuit that generates a signal to be supplied to a position detecting sensor and which houses a power storage device that provides a supply voltage to the electronic circuit and is chargeable. The electronic pen further includes a first conductor part and a second conductor part that are disposed to be exposed to outside to contactlessly form electric field coupling with power transmitting electrodes of a power transmitting part of an external charging device, to operate as power receiving electrodes. The electronic circuit includes a charging circuit that allows charging of the power storage device by being connected to the first conductor part and the second conductor part, and at least one of the first and second conductor parts is configured by part of the pen casing.
