Haptic feedback input device
First Claim
1. A haptic feedback input device comprising:
- an operating member that is manually operated by an operator;
a base that supports the operating member free to move;
a relative position detecting unit that detects the moving amount of the operating member;
an absolute position detecting unit that detects a reference position of the operating member;
actuators that apply feedback force to the operating member; and
a control unit that controls the actuators based on output signals from the relative position detecting unit and the absolute position detecting unit,wherein the absolute position detecting unit is composed of swing arms that move in conjunction with the operating member and detecting elements that detect the existence of the swing arms, respectively, and that output ON/OFF signals, andthe control unit computes the reference position of the operating member based on the change of the output of the detection elementwherein blocking portions protruding outwards as much as half of a swing angle of the swing arms are formed on the swing arms.

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.
