Title:
MOBILE TERMINAL AND NON-CONTACT BATTERY CHARGER
Document Type and Number:
Japanese Patent JP2016226076
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile terminal capable of reducing lowering of reception quality of a signal that is sent from communication equipment of a base station or the like even during charging.SOLUTION: A non-contact battery charger 1 comprises: a plurality of power transmission circuits 111-114; and a power transmission coil 120 that is shared by the plurality of power transmission circuits 111-114 and receives supply of power from one power transmission circuit which is selected from among the plurality of power transmission circuits 111-114. A mobile terminal 2 detects reception quality of a radio wave that is transmitted from communication equipment. Based on supply of power individual from each of the plurality of power transmission circuits 111-114 to the coil 120 in the state where the mobile terminal 2 is being mounted in the non-contact battery charger 1, the mobile terminal 2 identifies the power transmission circuit that is supplying power to the coil 120 when the reception quality becomes highest, from among the plurality of power transmission circuits 111-114. After the identification is performed, the mobile terminal 2 causes the identified power transmission circuit to supply power to the coil 120.SELECTED DRAWING: Figure 1
