Abstract: A battery charging apparatus, which can be part of a battery charging network, operates to detect insertion of a battery, and to read information on the inserted battery. The inserted battery can be charged, although a charged battery is immediately output from a battery charging apparatus upon the insertion of the battery to be charged. Further, the charging and outputting operations can be controlled based on the read information. Such a system of the present invention can find application in the charging of all batteries, including batteries for electrical automobiles.

Abstract: The battery disposal and collection apparatus includes a terminal connection having a terminal electrode pressed by a pressing structure on an upper cover, a battery guide case having a battery container to which the terminal electrode is inserted when the upper cover is closed, and which contains batteries, a rotary plate having an electrode terminal and a battery dropping hole on the plane of a rotary plate under the battery guide case. The electrode terminal contacts the terminal of a battery at the side opposite to the one at the terminal electrode when the terminal of the battery contained in the battery container contacts the terminal electrode. A battery discharger discharges current flowing between the terminal electrode contacting the terminal of the battery contained in the battery container and the electrode terminal. A battery receiver stores the battery which is discharged by the battery discharger and dropped through the battery dropping hole of the rotary plate.

Abstract: A portable facsimile machine used with various power sources, including an AC power source, a car battery power source and a rechargeable battery power source, has an improved operability. The portable facsimile machine comprises a main body performing a facsimile function and a power source adaptor provided separately from the main body. The power source adaptor is adapted for use with one of the various power sources. The portable facsimile machine is further provided with an attaching mechanism for detachably attaching the power source adaptor to the main body. The contact terminals of the power source adaptor automatically make contact with the contact terminals of the main body when the power source adaptor is attached to the main body by means of the attaching mechanism.
