PROBLEM TO BE SOLVED: To efficiently charge a built-in battery, wherever a battery built-in apparatus is placed on the top surface of a case.SOLUTION: A battery charger cradle charges a battery 52, built in a battery built-in apparatus 50 with power induced by an induction coil 51. The battery charger cradle comprises: a power supply coil 11 for inducing electromotive force to the induction coil 51; a case 20 having a top surface plate 21 for putting the battery built-in apparatus 50 on a top surface; a movement mechanism 13 for moving the power supply coil 11 along an inner surface of the top surface plate 21; and a position detecting controller 14 for detecting a position of the battery built-in apparatus 50 put on the top surface plate 21 to control the movement mechanism 13, and for allowing the power supply coil 11 to be brought closer to the induction coil 51 of the battery built-in apparatus 50. In the charging cradle, when the battery built-in device 50 is placed on the top plate 21 of the case 20, the position detection controller 14 detects the position of the battery built-in device 50, and the movement mechanism 13 makes the power supply coil 11 move, to be brought closer to the induction coil 51 in the battery built-in device 50. |
