Title:
ＮＦＣ充電可能なモバイル機器
Document Type and Number:
Japanese Patent JP6752597
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile device capable of effectively charging by a NFC.SOLUTION: When a secondary battery is charged by an electric current excited by electromagnetic induction by also using a NFC antenna for a communication, a guide display part guiding the NFC antenna for the communication to a correct position of the secondary battery is provided to a mobile device. A guidance is performed by a direction display that allows the mobile device to be moved on an upper surface of the secondary battery and a movement OK display. The guidance is intuitively performed on a front surface in parallel with the upper surface of the secondary battery. A guidance display is performed under a saved power that a partial region usage of a normal display surface, a single color driving, a back light reduction, and a reference clock frequency reduction in view of the fact that the guidance is a function at a secondary battery shortage. The secondary battery shortage is determined while remaining a surplus energy to be required for the guidance. A strength and a change of an electromagnetic field and the movement of the mobile device are detected and guided. The guidance is automatically continuously performed in a predetermined time with a hand operation. The guidance is continuously performed by a horizontal state detection of the mobile device or an existence detection of the electromagnetic field.SELECTED DRAWING: Figure 16
