The fixing plate includes plural openings, plural joining regions, and plural fixing regions. The plural fixing regions are arranged between the plural openings for fixing plural elastic elements of the plural keys. The proximity sensor includes an induction antenna circuit. The induction antenna circuit is formed on the plural joining regions or the plural fixing regions of the fixing plate for sensing whether an object enters a sensing range.
