  "textContent": "[Problem] To provide a system that allows a wireless power receiving device to be placed in the correct position with a simple configuration. [Solution] A wireless power transmission device () is equipped with a transmission-side coil (). Position indicator LEDs (, ) are provided on the centerline of the transmission-side coil () and are constantly illuminated. LEDs and are positioned symmetrically on either side of the transmission-side coil (). Power supply indicator LEDs (, ) are positioned outside LEDs and and are normally off. When the user places a smartphone (), which is a wireless power receiving device, above the transmission-side coil (), the wireless power transmission device () determines that it is in a state capable of supplying power and turns on LEDs and . This allows the user to confirm that power is being supplied.",
