To improve usability of a system using an electronic pen.SOLUTION: An electronic pen 10 has a communication unit 20 for communicating with a device to be communicated therewith, a state detecting unit 30 for detecting a state of the electronic pen 10 determined by its relationship with the device to be communicated therewith, and a controlling unit 40 for changing an operation of the communication unit 20 in response to the state detected by the state detecting unit 30. When the state of the electronic pen 10 is asynchronous state and a command of changing an operation mode is issued to a projector 100, the controlling unit 40 emits a light emitting unit 24 in a light emitting pattern for commanding cancellation of a standby mode. Therefore, the electronic pen 10 outputs a controlling signal for the light emitting pattern for commanding cancellation of the standby mode.SELECTED DRAWING: Figure 2 【課題】電子ペンを使用するシステムのユーザービリティを向上する。【解決手段】電子ペン１０は、通信対象の機器と通信する通信部２０と、通信対象の機器との関係で定まる電子ペン１０の状態を検出する状態検出部３０と、状態検出部３０が検出した状態に応じて、通信部２０の動作を変更する制御部４０とを含む。制御部４０は、電子ペン１０の状態が非同期状態で、プロジェクター１００に動作モードの変更を指示する場合、スタンバイモードの解除を指示する発光パターンで、発光部２４を発光させる。このため、スタンバイモードの解除を指示する発光パターンの制御信号が電子ペン１０から出力される。【選択図】図２
