[Prior Art] [0002] With the multi-touch brought by Apple's i P h ο n e smart phone

The control screen display craze gradually spread to the general notebook computer and desktop computer, and then designed a tablet with multi-touch display screen and AIO (ALL IN ONE) touch computer. The simple and intuitive operating interface allows the operator to easily zoom out directly from the screen on the display screen; ik, rotation, program » <. *' 'V;'·· Or multimedia files, such as broken play.

Please refer to Figure 1 for a schematic view of the appearance of a conventional touch computer. The touch computer 50 has a touch display screen 52, a casing 54 for accommodating the touch display screen, and a base 56 extending to the casing 54.
