<P>PROBLEM TO BE SOLVED: To promptly charge a battery for a mobile device by performing efficient electromagnetic coupling between an induction coil of the mobile device and a power supply coil of a charger cradle. <P>SOLUTION: The mobile device and the charger cradle include the mobile device 50 having a built-in induction coil 51 and a battery 54 and the charger cradle 10 for charging the battery 54 of the mobile device 50. The charger cradle 10, as the curved bottom 13 curved into a U groove of a bottom of an attachment part 12, includes a built-in power supply coil 21 inside a curved bottom 13, and connects a power supply 22 to the power supply coil 21. The mobile device 50 includes the built-in induction coil 51 inside a curved back surface 53 with a back surface placed on the attachment part 12 of the charger cradle 10 as a curved back surface 53 along the U grooved curved bottom 13. An attaching portion 12 of an upper case 11A has a posture in which the longitudinal direction of the U grooved curved bottom 13 is inclined in upper gradient toward the rear, and also has: a stopper wall 14 on the lower wall; and an optical guide 31 for irradiating the outside with the light emission of an LED 30 so as to be exposed on the stopper wall 14. <P>COPYRIGHT: (C)2010,JPO&INPIT |
