PROBLEM TO BE SOLVED: To efficiently charge built-in batteries no matter where multiple battery built-in apparatuses are placed on an upper surface of a case.SOLUTION: A charge stand is used for charging battery built-in apparatuses, each of which incorporates a power receiving coil and a battery charged by electric power induced by the power receiving coil. The charger includes: power transmitting coils 11 which are respectively and electromagnetically coupled to the power receiving coils and thereby induce electric motive force in the power receiving coils; a case which incorporates the power transmitting coils 11 and includes an upper surface plate 21 and a guide plate 23 facing the upper surface plate; moving mechanisms 40 to 48, each of which is incorporated in the case and moves the power transmitting coil 11 in X axis and Y axis directions along an inner surface of the upper surface plate 21 and causes the power transmitting coil 11 to come close to the power receiving coil of the battery built-in apparatus; and slide protruding parts 25 provided at the respective power transmitting coils 11. Each slide protruding part 25 contacts with an inner surface of the upper surface plate 21 or the guide plate 23 when the power transmitting coil 11 is moved in the X axis and Y axis directions. |
