PROBLEM TO BE SOLVED: To change drawing-out angle of an illuminator freely with no step by mounting the base end of extension/contraction arm on both side parts of a shelf board horizontally rotatably and mounting the tip end of the arm in the central position of a laterally long illuminator at an interval, horizontally rotatably. SOLUTION: An illuminator 12 is laterally long and set in its dimension shorter to some extent than the lateral width of an on-deck shelf 2. Under its state stored below the bottom surface of a shelf board 9, it is set to such a degree as allowing a space with a certain margin between both side ends and both side plates 8 so as to enhance the degree of freedom for positional change by extension/contraction of both extension/contraction arms 11. And in the illuminator 12, fluorescent lamps are arranged inside of its cover. When the arms 11 are in the most contracted state, approximately the entire of the illuminator 12 comes in its state stored below the bottom surface of the shelf board 9. When the arm 11 are in the most extended state, the entire of illuminator 12 goes in its state projecting sufficiently from the front end of the shelf board 9, the illuminator 12 is positioned nearly at the center of ceiling 5 so as to increase illumination in the front part of the ceiling 5. And neither one of hand shades of right-handed and left-handed users may appear. |
