An electronic device comprises a plurality of memory components, a connector, a receiver, and a communication component. The connector is configured to operatively connect the electronic device to an external device. The external device is capable of individually recognizing the memory components one at a time or simultaneously recognizing only a few of the memory components. The receiver is configured to receive a select instruction that specifies which of the memory components will be recognized by the external device. The communication component is configured to automatically communicate with the external device to permit the external device to automatically recognize at least one of the memory components as a predefined memory component. The communication component is further configured to communicate with the external device when the receiver receives the select instruction to permit the external device to recognize at least one memory components according to the select instruction.

Communication control device

Provided is an electronic device which is selectively connectable to two or more power sources thereby to charge the battery therein, and when connection with one power source is discontinued, the electronic device promptly switches connection to another power source thereby to start battery charging. When the external device connection sectionbecomes connected to an external device, while an AC connection sectionis connected to an AC power source, a control sectionperforms initial communication with the external device thereby to perform charge setting necessary for charging a batteryvia the external device.
