<p><P>PROBLEM TO BE SOLVED: To provide a battery pack capable of being thinned without interfering with the other member such as a pointing device, and without making a capacity small, an electronic apparatus having the battery pack, and an installation method of the battery pack. <P>SOLUTION: The battery pack 9 has first cases 45a and 45b having secondary batteries 52a and 52b built-in and a second case 46 having a control board 53 and a built-in wiring board 54, and the thickness of the second case 46 is smaller than those of the first cases 45a and 45b. Thereby, when the battery pack 9 is thinned, for example, areas of the first cases 45a and 45b are made larger and the second batteries 52a and 52b having larger areas can be built in, and thus, the deterioration of the capacity can be prevented. Moreover, since the arrangement location of the second case 46 with a small thickness can properly be established, the battery pack 9 can be installed on the electronic apparatus without interfering with the other member such as a pointing device. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
