The signal processing circuit sends the output electric signal to a processor in the mainboard circuit, so that the processor obtains the change of the signal level, namely the adsorption or the lifting of the writing component B can be known, and information is sent to the display module in a USB communication mode, so that the display module displays the responding prompt information.
