ABSTRACT:
An X-Y direction input device used, for example, in a graphic display apparatus includes some members enclosed in a casing and requiring electrical connection to each other. The casing is divided into upper and lower cases one of which has some chamber defining walls or ribs and the other has associated projections or pins, so as to accept the members previously connected physically, electrically to each other in the respective chambers and suppressingly support them in the chambers by the projections or pins.
