Abstract: A method of palm rejection is executed by a sensor controller that is connected to a plurality of sensor electrodes and that detects a downlink signal transmitted from an active pen. The method includes determining whether or not a phase of the detected downlink signal matches a phase shared in advance between the sensor controller and the active pen, and outputting, when it is determined that the phases match, a position of the active pen derived on the basis of a distribution of levels of the downlink signal in the plurality of sensor electrodes.

Abstract: An auxiliary device according to the present disclosure includes a ruler part, a plurality of electrodes provided at the ruler part, a receiving electrode for receiving an uplink signal transmitted from a sensor controller, and a processor that transmits a downlink signal to the sensor controller while sequentially switching the plurality of electrodes in response to reception of the uplink signal.

Abstract: A light irradiation unit forms an electrostatic latent image pattern on a photosensitive member by irradiating the photosensitive member and a shielding unit with light. A detection unit detects, in a rotation direction of the photosensitive member, timing at which a surface potential of the photosensitive member changes depending on displacement of the electrostatic latent image pattern in an axial direction of the photosensitive member.
