Abstract

The invention aims at providing a wireless incoming device and an electronic apparatus with the wireless incoming device. Wherein, the production cost does not increase even when the frequency of the electromagnetic wave receiving for power supply changes. Besides, the invention also aims at providing a wireless incoming device that the power can be transmitted by the manner of no wire break or poor connection when the load of power supply and the batter connected to the aerial are produced by different processes. The wireless incoming device of the invention comprises a power receiving part and a load part. The power receiving part is provided with a first aerial circuit, a second aerial circuit and a batter part. The load part is provided with a third aerial circuit. The battery of the battery part is charged through the first wireless signal receiving from the first aerial circuit and the power in the battery part is transmitted from the second aerial circuit as the second wirelesssignal. The third aerial circuit receives the second wireless signal to supply power to the load.

Description

technical field [0001] The present invention relates to a wireless power receiving device that supplies electric power wirelessly. Background technique [0002] The popularization of various electronic appliances is accelerating, and various products appear on the market in droves. Especially in recent years, the popularity of portable electronic appliances used outdoors has been remarkable. [0003] As an example of a portable electronic device used outdoors, research and development for the practical use of an RFID (Radio Frequency Identification) tag (hereinafter referred to as an RF tag) as an information transmitting and receiving device is being actively carried out. RF tags can be classified into two types: an active type (active type) RF tag and a passive type (passive type) RF tag. In addition, in addition to active type RF tags and passive type RF tags, a battery is provided to secure a power source for driving the RF tag, and the technology of charging the batte...
