Abstract
An operation input device includes a base, a printed circuit board which has a plurality of pushbutton switches and Hall elements mounted on its upside and which is stacked on and united with the base, an operation plate which is supported on the base so as to be vertically movable on the printed circuit board, and a disc type operation dial in which an annular magnet with N-poles and S-poles arranged alternately is assembled on the underside of this operation dial and which is turnably assembled on the upside of the operation plate. Here, the disc type operation dial is turned, thereby to sense the changes of the magnetic fluxes of the annular magnet by the Hall elements and to detect a turning direction, while the disc type operation dial is depressed, thereby to operate any of the pushbutton switches through the operation plate. The operation dial is prevented from becoming rickety in a horizontal direction, and it ensures a smooth turning operation, thereby to afford a good operation feeling.
