Abstract
A scrolling device of human interface device and human interface device using the same is disclosed. The scrolling device of human interface device includes a plurality of touch sensing pads and performs scroll operation by sensing contact of at least one of the plurality of touch sensing pads. Thus, it is possible to prevent a mechanical noise and malfunction caused by mechanical abrasion. Further, it is possible to sense upward and downward scroll movement as well as leftward and rightward scroll movement, thus providing still more various scroll information, so that it is possible to make good use of the scrolling device of human interface device.
