Summary:In an embodiment of the invention, a metal shield case and a metal shutter are electrically conducted to each other by using a contact part and are made to have the same potential. By this, the shutter does not electrically exert a bad influence on detection accuracy of a surface potential sensor, the closing performance of the shutter is improved, and the miniaturization or reduction in cost of the surface potential sensor can be realized.
