1. A wireless power transmitting method of a wireless power transmitting apparatus,wherein a standby state of determining whether at least one wireless power receiving apparatus is positioned within a wireless charge range of the wireless power transmitting apparatus and a power transfer state of transmitting power to the corresponding wireless power receiving apparatus when at least one wireless power receiving apparatus is detected in the standby state are provided, andthe standby state includes a first standby state of periodically transmitting a weak detector signal and a strong detector signal and a second standby state in which at least one of a transmission period of the weak detector signal and a transmission period of the strong detector signal is different from that of the first standby state, the method comprising:

  • determining any one state of the first standby state and the second standby state of the wireless power transmitting apparatus; and

    transmitting the weak detector signal and the strong detector signal based on the determined standby state,wherein the transmission period of the weak detector signal in the second standby state is longer than the transmission period of the weak detector signal in the first standby state.
