Abstract
A touch pen with erasure function, applied for an electronic apparatus having a touch screen, comprises a body and a sensing unit. The body holds a accommodating space for disposing the sensing unit therein, and has a writing end and an erasing end. While detecting that the touch pen is held with the writing end located close to the touch screen, the sensing unit generates a first signal to the electronic device for allowing the touch pen to write a message on the touch screen. When detecting that the touch pen is held with the erasing end located close to the touch screen, the sensing unit generates a second signal to the electronic device for allowing the touch pen to erase the message on the touch screen.
