Abstract
The present invention Provides a position detector includes a scale provided with a recording medium recorded with information for position detection; a slider disposed to face the recording medium of the scale and to relatively travel along an elongate direction of the scale and provided with a detection sensor for detecting the information of the recording medium, a carrier for carrying the slider, and a posture control mechanism disposed between the carrier and the slider to control slider posture relative to the scale. The posture control mechanism is located on a straight line being vertical to a plane provided with the recording medium facing the detection sensor and passing the detection sensor and biases the slider toward the scale in the direction of the straight line for posture control. The slider is provided with a guide restricting section slidably contact with the scale to restrict a biasing force of the posture control mechanism.
