<p><P>PROBLEM TO BE SOLVED: To provide a cradle configured to switcih a charging object of a DAP (Digital Audio Player) based on charging levels of DAPs 2, 3. <P>SOLUTION: The cradle selects a DAP to be preferentially charged by acquiring the charging levels of the DAPs 2, 3 from the DAPs 2, 3, and comparing the charging levels of the DAP 2 with the charging level of the DAP 3. When the charging level of the DAP 2 is below the charging level of the DAP 3, and the DAP 2 is selected as the DAP to be preferentially charged, a switch 1G connects a connector 1L to a host controller 1B at first, whereby the host controller 1B transmits a charging command to the DAP 2 to charge the DAP 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
