た。in general, ! ! In optical device movable copying IIA, it is necessary to supply power to a movable table equipped with an exposure lamp, but the conventional method of running electrode wires through an insulated substrate along the traveling rail of the movable table has not been possible since the movable table is equipped with an exposure lamp. Generally, current is collected by bringing a current collecting brush provided on a stand into sliding contact with the electrode wire. By the way, the conventional electrode wires are composed of elongated printed circuit boards, etc., and the printed circuit boards are fixed to the running rails of the movable platform, making the assembly process cumbersome.
