Abstract
A haptic feedback input device includes a pair of driving levers journaled at a frame such that rotary shafts thereof are perpendicular to each other, an operating lever coupled to an intersection of the two driving levers such that it can rock, and a pair of rotary motors that apply feedback force to the operating lever via the two driving levers. In the haptic feedback input device, a pair of rotary encoders detect the relative dislocation amount of the operating level, and an absolute position detecting unit is composed of swing arms fixed to the two driving levers and photo interrupters that detect the existence of blocking portions formed at the swing arms and that output ON/OFF signals. A control unit calculates a reference position of the operating lever based on ON/OFF switching signals of the photo interrupters.
