A pedestal type device that functions as anon-limiting example charger comprises a connection portion that is constituted by a connection plug and a cover. The cover is supported so as to be movable up and down through a second hole of a placement portion. Furthermore, a convex portion that is protruded toward a front side is provided in a center of a lower end portion of a rear support portion. Two first projections are formed on an upper surface of the cover, and a first hole is formed between them. The connection plug is supported so as to be movable up and down through a third hole. If the convex portion is fitted into a first concave portion formed in a rear surface of electronic device when the electronic device is placed on the placement portion, the first projections are respectively fitted into two third concave portions formed on an undersurface of the electronic device, whereby the cover is pushed down. Therefore, the connection plug is inserted into the depths of a connector of the electronic device.
