Abstract
An electronic pen includes a rectifier circuit, a first integrated circuit, and a second integrated circuit. The rectifier circuit, in operation, stores a voltage in a first capacitor based on energy received from a position detecting device. The first integrated circuit operates using the voltage stored in the first capacitor. The first integrated circuit, in operation, controls transmission of a first signal that is wirelessly transmitted from a pen tip. The second integrated circuit, in operation, wirelessly transmits a second signal after the voltage stored in the first capacitor is greater than a predetermined voltage.
