Abstract

The present invention discloses a structure for preventing the loss of a pen of an electronic device comprising a pen holding slot, a sensor switch disposed in the pen holding slot, and a control circuit being electrically connected to the sensor switch, so that if the pen is not placed into the pen hold slot, the sensor switch will send a non-press signal to the control circuit, enabling the control circuit to turn on a beeping circuit to generate a warning sound to remind users to place the pen back into the pen holding slot. Therefore, the present invention can prevent the loss of the pen by the reminder of such warning sound.
