近场无线通信装置、以及其控制方法
Abstract:
本发明的NFC通信设备具备：天线部(101)，通过近场无线通信从读写器设备(20)接收电波；第一电源部(102)，通过接收的电波产生电力；第二电源部(104)，是驱动电源；电源状态保持部(107)，保持表示第二电源部(104)的电源状态的信息；近场无线通信部(606)，经由天线部(101)将表示第二电源部(104)的电源状态的信息进行近场无线通信；电源切换部(103)，按照第二电源部(104)的电源状态，将用于驱动近场无线通信部(606)和电源状态保持部(107)的电力从第二电源部(104)切换到第一电源部(102)，电源切换部(103)，在第二电源部(104)的电源是断开的电源状态的情况下，从第二电源部(104)切换到第一电源部(102)。
Abstract(English):

An NFC device according to the present invention includes the following units. An antenna unit (101) receives radio waves from a reader/writer (20) by NFC. A first power source unit (102) generates power from the radio waves. A second power source unit (104) is a drive power source. A power-supply state holding unit (107) holds information indicating a power-supply state of the second power source unit (104). An NFC unit (606) performs NFC via the antenna unit (101) to transmit the information indicating the power-supply state of the second power source unit (104). A power source switch unit (103) switches the second power source unit (104) to the first power source unit (102) according to the power-supply state of the second power source unit (104), in order to supply power to activate at least the NFC unit (606) and the power-supply state holding unit (107). Here, the power source switch unit (103) switches the second power source unit (104) to the first power source unit (102), when the information indicates that the second power source unit (104) is powered OFF.
