Abstract
Abstract Electronic equipment includes a container unit for storing a battery or an AC adaptor which are detachable from the container unit and exchangeable with each other, an input port unit for receiving electric power from an external source, and a connection attachment unit for storing the battery and the AC adaptor which are detachable from the connection attachment unit, so that the AC adaptor can be stored in the connection attachment unit to supply DC power to the electronic equipment through the input port in order to charge the battery stored in the container unit, so that another battery can be stored in the connection attachment unit to supply DC power to the electronic equipment through the input port in order to serve as an expansion battery in addition to the battery stored in the container unit, or so that both the battery and the AC adaptor can be stored in the connection attachment unit to charge the battery.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
143 words
Electronic equipment comprising: a main device configured to receive power from one of a battery and an AC adaptor stored in a container of said main device; attachment means for supplying power to said main device when one of said battery and said AC adaptor is stored in said attachment means, said attachment means comprising: a battery container for storing said battery; an AC-adaptor container for storing said AC-adaptor; battery detecting means for detecting said battery in said battery container; and switch means, responsive to said battery detecting means, for supplying power of said AC adaptor to said battery through electrodes of said battery container when both said battery and said AC-adaptor are stored in said attachment means, and for preventing said power of said AC adaptor from being exposed at said electrodes when said battery is not stored in said battery container.
Claim 2
Dependent Claim
143 words
Electronic equipment comprising: a main device configured to receive power from one of a battery and an AC adaptor stored in a container of said main device; attachment means for supplying power to said main device when one of said battery and said AC adaptor is stored in said attachment means, said attachment means comprising: a battery container for storing said battery; an AC-adaptor container for storing said AC-adaptor; battery detecting means for detecting said battery in said battery container; and switch means, responsive to said battery detecting means, for supplying power of said AC adaptor to said battery through electrodes of said battery container when both said battery and said AC-adaptor are stored in said attachment means, and for preventing said power of said AC adaptor from being exposed at said electrodes when said battery is not stored in said battery container.
Claim 3
Dependent Claim
68 words
