Abstract

A portable electronic device including a main body and a wireless input unit is provided. The main body has a display surface and an accommodating portion opposite the display surface. The accommodating portion defines an accommodating space substantially parallel to the display surface. The wireless input unit is placed inside the accommodating space and capable of being extracted from the accommodating space. The wireless input unit is separate from the main body. The wireless input unit includes a touch panel, a pattern layer, and a control circuit. The touch panel has an operation surface and a back surface opposite the operation surface. The pattern layer is disposed on the back surface of the touch panel and has a plurality of control area patterns. The control circuit is disposed on the touch panel.

Claims
