To provide a noncontact power supply system for reducing power consumption of a power supply device when power is supplied to a communication device which performs radio communication with a portable machine and the portable machine in a noncontact manner.SOLUTION: A noncontact power supply system 1 comprises: a radio communication unit 10 which performs radio communication with a portable machine P; a noncontact power supply unit 20 which supplies power to the portable machine in a noncontact manner; and a control unit 30. A control mode of the noncontact power supply system includes a first mode for stopping the noncontact power supply unit while performing polling by the radio communication unit, and a second mode for actuating the noncontact power supply unit while performing the polling by the radio communication unit. The control unit continues stop of the noncontact power supply unit until authentication of the portable machine is established in the first mode, and starts the noncontact power supply unit to switch the control mode to the second mode when the authentication of the portable machine is established in the first mode.SELECTED DRAWING: Figure 1

    【課題】携帯機との間で無線通信を行なう通信装置と携帯機に非接触で給電する際に、給電装置の消費電力を低減する非接触給電システムを提供する。【解決手段】非接触給電システム1は、携帯機Pとの間で無線通信を行なう無線通信ユニット10と、携帯機に非接触で給電する非接触給電ユニット20と、制御ユニット30と、を備える。非接触給電システムの制御モードには、無線通信ユニットによるポーリングを行ないつつ非接触給電ユニットを停止する第1モードと、無線通信ユニットによるポーリングを行ないつつ非接触給電ユニットを作動する第2モードとが含まれる。制御ユニットは、第1モード中において、携帯機の認証が成立するまでは、非接触給電ユニットの停止を継続し、第1モード中において携帯機の認証が成立した場合、非接触給電ユニットを起動して制御モードを第2モードに切替える。【選択図】図1
