Abstract
This handheld-terminal charging device has a plurality of charging coils, a plurality of detection coils, and a control unit that is electrically connected to said charging coils and detection coils. The control unit drives the plurality of detection coils and watches for impedance changes that said detection coils detect when thus driven. If a detection coil detects an impedance change, a charging coil corresponding to said detection coil is selected from among the plurality of charging coils and a magnetic field is outputted from the selected charging coil. If a response signal that has been agreed upon with a handheld terminal is received in response to said magnetic field, the selected charging coil is used to charge said handheld terminal.
