An electrostatic receiving mechanism of an electronic indicating device installed on the electronic indicating device and electrically connected to a grounding circuit of a circuit board is provided. The electrostatic receiving mechanism mainly includes a frame, a roller mechanism, and a supporting beam. The roller mechanism is assembled onto the frame and the frame and the roller mechanism may slide relative to each other along the guide rails of the frame, and the supporting beam is made of a metallic conductive material and electrically connected to the grounding circuit. The supporting beam has an extension arm extending towards and close to an outer edge of the roller mechanism, thereby forming an electrostatic receiving mechanism.
