摘要： A keyboard apparatus permits easier installation of slide retaining pins to a retaining portion and prevents intrusion of dust into the keyboard apparatus from the back surface of a supporting substrate thereof. A first retaining portion has a narrow area and a wide area, and slide retaining pins are latched in the wide area. A dust-proof sheet is provided on the bottom surface of a supporting substrate to cover through holes in the supporting substrate, the through holes resulting from the formation of the first retaining portion and second retaining portions.
