<p><P>PROBLEM TO BE SOLVED: To provide a printer system which can decrease consumption of electric power stored in a battery by using a solar cell in a small-sized portable printer driven by the battery. <P>SOLUTION: The solar cell 30 is provided on the surface of an attaching implement 20 for mounting the portable printer 10 on a body, and the batteries (a first battery 13 and a second battery 14) for driving the portable printer 10 are charged by the electric power generated by the solar cell 30. Either the first battery 13 or the second battery 14 whose amount of storage of electricity is less is charged by the electric power generated by the solar cell 30. When operation of the portable printer 10 is indicated, the portable printer 10 is driven by the electric power stored in either of the first battery 13 or the second battery 14 whose amount of storage of electricity is more. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
