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 a 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 detection targets that move in conjunction with the operating member and detecting elements that detect the existence of the detection targets, respectively, and that output ON/OFF signals, and the control unit computes the reference position of the operating member based on changes of outputs of the detecting elements.
