摘要：
A position detector includes a magnet, a pair of Hall effect devices, and a processing circuit for detecting relative positions of the magnet and the pair of Hall effect devices. The processing circuit detects a difference in magnitude between output values of the Hall effect devices, as position outputs, with an input value to each of the Hall effect devices being controlled such that a sum of magnitudes of respective output values of the Hall effect devices is constant.
