から遮蔽するために、該受光回路をメイン回路基
板と共に包囲するシールドケースに対して、該受
光素子の受光面に離間対向する位置に、打抜きに
よる網目を穿設してなる受光装置。 In order to shield at least a light-receiving circuit including a light-receiving element from electromagnetic induction, a punched mesh is formed in a shield case that surrounds the light-receiving circuit together with the main circuit board at a position spaced apart from and facing the light-receiving surface of the light-receiving element. A light receiving device is installed.
