Abstract:
1. A charging apparatus for charging a secondary battery when mounting an apparatus having a built-in secondary battery on a battery charger, the charging apparatus comprising: the battery charger comprising an engaging section and a contact member; and an electrode for supplying power to the secondary battery upon establishing contact between an engaged section engaging with the engaging section and the contact member, wherein when the apparatus is mounted on the battery charger so as to engage the engaged section with the engaging section, the electrode is press-attached against the contact member with a force greater than a weight of the device due to an angular moment centered about the engaging section of the apparatus due to the weight of the apparatus, and a receptacle surface of the battery charger forms a substantial circular arc shape wherein the engaged section is engaged by the engaging section when the apparatus is turned on the receptacle surface, and the electrode stops at a position where contact is made with the contact member.
