Abstract

PURPOSE: The quantity of light of an illuminant is made to change in order by a screening object, allowing the passed light to illuminate the photoelectric element, whereby the quantity of current depending on the passed light is obtained, thus providing an improved electric-current-controlapparatus replacing the variable resistance.
