摘要：PROBLEM TO BE SOLVED: To provide a mobile device capable of effectivelycharging by a NFC.SOLUTION: When a secondary battery is charged by an electric currentexcited by electromagnetic induction by also using a NFC antenna for a communication, aguide display part guiding the NFC antenna for the communication to a correct positionof the secondary battery is provided to a mobile device. A guidance is performed by adirection display that allows the mobile device to be moved on an upper surface of thesecondary battery and a movement OK display. The guidance is intuitively performed ona front surface in parallel with the upper surface of the secondary battery. A guidancedisplay is performed under a saved power that a partial region usage of a normal displaysurface, a single color driving, a back light reduction, and a reference clock frequencyreduction in view of the fact that the guidance is a function at a secondary batteryshortage. The secondary battery shortage is determined while remaining a surplusenergy to be required for the guidance. A strength and a change of an electromagneticfield and the movement of the mobile device are detected and guided. The guidance isautomatically continuously performed in a predetermined time with a hand operation.The guidance is continuously performed by a horizontal state detection of the mobiledevice or an existence detection of the electromagnetic field.SELECTED DRAWING: Figure
