    摘要: An electric potential measuring apparatus includes a movable portion having a detecting electrode and a magnetic force receiver, a magnetic force generator, an electric field shield, and a detector for detecting an amount of an electric charge which is electrostatically induced on the detecting electrode. The electric field shield transmits a magnetic field generated by the magnetic force generator to make it arrive at the magnetic force receiver but shields the detecting electrode from an electric field generated by the magnetic force generator to interrupt arrival to the detecting electrode and not to substantially obstruct the detection by the detector.

    摘要: An electric potential sensor includes a detecting electrode, a capacitor modulating unit for modulating a coupling capacitance between the detecting electrode and a measurement object by using an electrostatic force, and a shielding unit for electrically shielding the detecting electrode from electric fields due to the electrostatic force of the capacitor modulating unit. An electric potential of the measurement object is measured based on a change caused by the capacitor modulating unit in the amount of electrical charge induced in the detecting electrode. Entrance of lines of electric force due to the electrostatic force of the capacity modulating unit into the detecting electrode is prevented or reduced, so that an unfavorable mixture of driving noise into an output signal of the detecting electrode can be prevented or reduced.
