When the electronic device 1 is attached to the frame 21, additional power is supplied from the battery 26 of the frame to the electronic device through external terminals (6). Although the electronic device has an internal battery, it becomes possible to change the battery capacity by connecting the electronic device to the battery of the frame. This constitution makes it possible to easily add various optional functions to the electronic device. By preparing a variety of frames with different battery capacities, a user can select a frame with a necessary battery capacity depending on the purpose in using the electronic apparatus. <IMAGE> |
