Abstract:
A transmission-type electronic pen that detects a hover state by a position detecting device and achieves power savings is provided. The pen includes a transmission circuit that transmits a signal to a position detecting device and a detector configured to detect a direct act of a user. The pen includes a pressure detector configured to detect whether a pressure is applied to a tip of a core body, and a controller configured to activate and control transmission operation of the transmission circuit based on detection outputs of the detector and the pressure detector. The transmission circuit is controlled in accordance with any of a plurality of transmission operation states including at least a power saving state. When detecting an act of the user, the controller activates and sets the transmission circuit to a first transmission operation state of the plurality of states.
