摘要

An electronic apparatus has a touch pen. The touch pen includes a pen tube and an antenna. The pen tube has a hollow tube body and a touch end. The tube body is used to accommodate the antenna. Further, the antenna has a fixed tube body and a telescopic tube body. The interior of the fixed tube body is provided with electronic circuit and is electrically connected with the telescopic tube body. Therefore, when the touch pen is accommodated in the electronic device and is electrically connected with the electronic device, the electronic device can receive the wireless signals via the antenna within the touch pen. Alternatively, the antenna is provided within the electronic device directly and is electrically connected thereto, so that the electronic device can be kept to have a function of receiving the wireless signals during the use of the touch pen.
