REFERENCE POTENTIAL GENERATOR

摘要

PROBLEM TO BE SOLVED: To propose a reference potential generator capable of supplying stable reference potential.

SOLUTION: A reference potential generator 1 comprises: m (m is an even number equal to or greater than four) electrodes 21A to 21D that are arranged around a reference position in a rotationally symmetric manner; application means for applying electrical charge whose intensity within an adjacent range including the reference position is less than a predetermined value to the m electrodes 21A to 21D; multiple conductors 31A and 31B that are arranged in the range; and amplification means 33 for amplifying a difference between signals obtained from a plurality of conductors 31A and 31B arranged in the range.
