<p><P>PROBLEM TO BE SOLVED: To provide a non-contact charger which can hardly influence communications of an on-vehicle system. <P>SOLUTION: A non-contact charger 14 can charge a battery 23 of a mobile phone 13 in a non-contact manner by a charge electric wave Svc and has an LF antenna 25 which can receive a smart signal of an LF electric wave which is communicated with a key operation free system 3. The LF antenna 25, in which a high Q-value is set, is connected to a controller 15 through a band-pass filter 26 and an amplifier 26a. In electric wave reception by the LF antenna 25, only electric wave which passes through a reception band determined by the band-pass filter 26 and the LF antenna 25 having the high Q-value is acquired. When detecting that a high induction voltage is generated in the LF antenna 25, the non-contact charger 14 controls an output of the charge electric wave Svc so that the charge electric wave Svc may not influence the smart signal. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
