NON-CONTACT CHARGING SYSTEM, AND CHARGER AND ELECTRONIC EQUIPMENT FOR USE IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a non-contact charging system for performing power supply through transmission/reception of a magnetic field, in which efficient power supply is realized by individually optimizing transmission/reception of power supply and a command and suppressing mutual interference.SOLUTION: A non-contact charging system according to the present invention includes: a charger that transmits a magnetic field for supplying electric power; and electronic equipment that receives the electric power through reception of the magnetic field. The charger includes: a transmission unit for transmitting the magnetic field; and a transmission/reception unit for transmitting a recognition signal to the electronic equipment and receiving an activation signal transmitted from the electronic equipment. The electronic equipment includes: a reception unit for receiving the magnetic field; and a reception/transmission unit for receiving the recognition signal and transmitting the activation signal. The charger transmits the magnetic field on the basis of the activation signal and the electronic equipment receives the magnetic field on the basis of the recognition signal.
