Abstract

A touch pen includes a sleeve, a contact element, a sensing device and a buffering element. The contact element is penetrated through the sleeve and movably relative to the sleeve. The sensing device is disposed within the sleeve. The buffering element is disposed within the sleeve. The contact element and the sensing device are separated from each other by the buffering element. While the contact element is moved in response to an external force applied to touch pen, the impact of the contact element on the sensing device is largely reduced because the contact element and the sensing device are separated from each other by the buffering element. Moreover, since the external force is received by the buffering element, the sensing device can be protected by the buffering element. Consequently, the failure probability of the touch pen is reduced.

Dependent claims

A touch pen for a capacitive touch pad, the touch pen comprising:

a main body;
a contact element disposed on the main body and partially protruded out of the main body, wherein when the contact element is contacted with the capacitive touch pad, a touch signal is transmitted to the capacitive touch pad through the contact element;
a sleeve disposed within the main body, wherein the contact element is penetrated through the sleeve and movably fixed on the sleeve;
a sensing device disposed within the sleeve, wherein in response to a movement of the contact element, the sensing device is triggered to generate the touch signal;
and
a buffering element disposed within the sleeve and contacted with the contact element and the sensing device, wherein the contact element and the sensing device are separated from each other by the buffering element, and the touch signal is transmitted to the contact element through the buffering element.
