Patent attributes
In a rotary input apparatus, an operational end enabled to be rotationally operated is provided, an operational input device detects a rotational displacement of the operational end to move a pointer displayed on a display thereof to perform a selection operation of any one of various kinds of selection items displayed on the display and a driving force generating section generates and transmits a driving force to the operational end in accordance with a reaction force pattern when the operational end is rotationally operated, the operational input device setting the reaction force pattern against the rotational displacement of the operational end and varying the reaction force pattern on the basis of an input signal from at least one of an internal of and an external to the operational input device when the operational end is rotationally operated.
