On the other hand, such a notebook PC has a built-in battery that has a force ^s that does not last as long as the force ^s . If you do not have to carry an external power adapter, a window system or the like is used for the operating system (OS). Although a pointing device is required, the notebook PC has a built-in pointing device, but it does not have an external pointing device. (Referred to as “mouse”) has gained a lot of support, making it easy to use and making it an essential feature. The size of the mouse is generally about 30 in accordance with the size of the user's hand. Those that become heavier are not suitable. Therefore, when carrying an external power adapter in addition to a notebook PC, a mouse is often not carried, but this poses a problem in that the operability of the notebook PC is reduced.

Accordingly, an object of the present invention is to provide a power adapter that can be used as an external pointing device.
