The amount of protrusion is adjusted so that the coil 51 can approach the power supply coil 21 of the charging stand 10. Further, the wing portions 47 provided on both sides of the guide convex portion 46 have a projection amount smaller than that of the guide convex portion 46, and the guide convex portion 46 is placed in a state where the lower end of the wing portion 47 is in contact with the stopper wall 14. The guide can be guided to the guide recess 14A. In the positioning case 45 described above, the lower end of the wing portion 47 is brought into contact with the stopper wall 14 of the charging stand 10 and the guide convex portion 46 is guided to the guide concave portion 14A. It can be placed at an accurate position. The positioning case 45 disposed at a fixed position of the mounting recess 12 can efficiently charge the battery pack 70 by arranging the inserted battery pack 70 at an accurate position of the mounting recess 12.

  The positioning case 45 is attached to the portable device 50 with the relative position between the induction coil 51 and the power supply coil 21 in a state where the battery pack 70 separated from the portable device 50 is attached and set in the attachment recess 12. Thus, the battery can be charged efficiently and promptly at the same position as the state of setting in the mounting recess 12. In particular, the portable device 50 that is covered with the cover 40 and set in the mounting recess 12 has the cover 40 disposed between the battery pack 70 and the mounting recess 12 as shown in FIG. Therefore, as shown in FIG. 7, the positioning case 45 is mounted on the portable device 50 covering the cover 40 with the battery pack 70 mounted and set in the mounting recess 12. Thus, charging can be performed efficiently and quickly so that the relative position between the induction coil 51 and the power supply coil 21 in the state of being set to the same position as that of the power coil 21 is set. However, in the positioning case 45, the induction coil 51 is brought closer to the power supply coil 21 than the relative position between the induction coil 51 and the power supply coil 21 in this state, and the battery 54 is quickly charged by efficiently conveying power. be able to. However, the positioning case is in a state where the battery pack is mounted and set in the mounting recess, and even if the induction coil is slightly separated from the power supply coil, all the power can be conveyed by electromagnetically coupling the power supply coil and the induction coil. Can be used in the state.

  The mobile device 50 described above can be charged on the battery pack 70 by being set on the charging stand 10 with the battery pack 70 attached. Alternatively, the battery pack 70 can be taken out and mounted on the positioning case 45 and set on the charging stand 10 to charge the battery pack 70. Further, since the AA battery 54B can be inserted into the battery mounting portion 61 of the portable device 50 and used while the battery pack 70 is taken out and charged by the charging stand 10, the user can use the packed battery while using the portable device 50. 70 can be charged and used conveniently. However, the battery mounting portion does not necessarily have to have a shape capable of mounting an AA battery. This is because by using a plurality of battery packs, one battery pack can be placed in a positioning case and charged while another battery pack is set in the mobile device to use the mobile device.
