The medical equipment where electric power is supplied with the wireless by the resonance magnetic field, when it is brought within threshold radius, connects to the electrical transmitter inside control unit automatically. With one execution form, control unit identifies the medical equipment automatically, changes itself setting automatically and controls the medical equipment. Furthermore, as for the video endoscope system which has the electrical tranceiver which generates the endoscope and the resonance magnetic field, as for the aforementioned endoscope, it includes with the image pickup vessel and endoscope tranceiver which supplies electric power to the illuminant, resonance interaction occurs with the aforementioned endoscope tranceiver and the aforementioned electrical tranceiver, in order for electric power to be transmitted to the aforementioned endoscope tranceiver by the aforementioned resonance interaction, the aforementioned endoscope tranceiver is aligned in the aforementioned resonance magnetic field.共振磁界によってワイヤレスで電力が供給される医療機器は、閾値半径内に持ち込まれると制御ユニット内の電力伝送器に自動的に結合する。一実施形態では、制御ユニットが自動的に医療機器を識別し、自動的に自身の設定を変えて医療機器を制御する。さらに、内視鏡と共振磁界を発生する電力トランシーバとを備えたビデオ内視鏡システムは、前記内視鏡は、撮像器および光源に電力を供給する内視鏡トランシーバとを含み、共振相互作用が前記内視鏡トランシーバと前記電力トランシーバとの間に発生し、前記共振相互作用によって電力が前記内視鏡トランシーバへ伝送されるように、前記内視鏡トランシーバは、前記共振磁界に同調される。
