防滴構造。[Claims for Utility Model Registration] A conductive rubber type keyboard device using a conductive rubber contact as a contact element in a rubber cup, comprising a plurality of said rubber cups and a contact rubber in which said conductive rubber contacts are molded inside said rubber cup. It consists of a sheet, a substrate located at the bottom of the contact rubber sheet and having at least an electrode pattern and a keyboard control circuit that are paired with the conductive rubber contacts and constitute a key switch, a key top, and an upper cover and a lower cover for storage. In the keyboard device, a passageway connecting the insides of the rubber cups and a surface other than the top surface of the contact rubber sheet connected to the passageway are provided in order to prevent air inside the rubber cups from being compressed and pressing pressure to increase. , a vent communicating with the outside air; a wall surrounding the hole of the rubber cup and the first, second, and third sides of the three sides of the contact rubber sheet; and a remaining wall of the contact rubber sheet that does not have walls. means for flowing liquid from the fourth surface; a tongue portion extending one end of the contact rubber sheet on the fourth surface beyond the tip of the substrate; means for bending the tongue portion downward; A drip-proof structure for a keyboard device, characterized in that it is provided with a means for causing liquid to flow out to the outside.
