To supply necessary power to drive a device with an HMD attached, and enable the continuous use of the HMD.SOLUTION: An HMD 100 includes a plurality of power receiving units 102a and 102b mounted with first and second batteries 200a and 200b and receiving power from the first and second batteries by wireless transmission, a power management unit 106 that monitors the states of the first and second batteries, a communication unit 108 that performs wireless communication with the first and second batteries, and a plurality of limiting units 104a and 104b that limit the power received by the plurality of power receiving units. The control unit 101 limits the power supplied to a load via the limiting unit according to the power usage status of the load in the device, and the power management unit obtains information on the remaining charge amount of the first and second batteries via the communication unit and displays the obtained information on a display 119.SELECTED DRAWING: Figure 5A 【課題】ＨＭＤを装着したままで装置駆動に必要な電力の補給ができ、ＨＭＤの継続使用を可能とすること。【解決手段】ＨＭＤ１００は、第１、第２のバッテリー２００ａ，ｂを装着し、該第１、第２のバッテリーから無線伝送により電力を受電する複数の受電部１０２ａ，ｂと、第１、第２のバッテリーの状態を監視する電源管理部１０６と、第１、第２のバッテリーとの間で無線通信を行う通信部１０８と、複数の受電部にて受電した電力を制限する複数の制限部１０４ａ，ｂと、を備える。制御部１０１は、装置内の負荷の使用電力状況に応じ、制限部を介して負荷に対して供給する電力を制限し、電源管理部は、通信部を介して第１、第２のバッテリーの残存蓄電量の情報を取得して、取得した情報をディスプレイ１１９に表示する。【選択図】図５Ａ
