PROBLEM TO BE SOLVED: To copy the front view of an article correctly conforming to a drafting practice. SOLUTION: A frame 50 is formed into a prismatic shape, and on the bottom face, a floor 57 is provided, and all the other five faces are opened. On guide bars 59, 62 which are provided on the frame 50 in the longitudinal direction, both end parts of a contact member 70 are slidable fitted, and the article 100 which is normally placed on the floor 57 can be fixed with fixing screws 74, 75 under a being pressed state from the top. On the guide bars 59, 62, reels 80-85 where both ends of wires 86, 90, 93 being laid along the back face of the article 100 are fitted slidably in the vertical direction and rotatably around the axes. For example, one end side of the wire 86 is wound by rotating the reel 80 counterclockwise, and the other end side of the wire 86 is wound by rotating the reel 81 clockwise, and the wire 86 is fixed under a tightly stretched state with the fixing screws 88, 89, and the article 100 is pushed forward. The other reels are wound in the same manner, and when the frame 50 is laid in such a manner that the back face of the frame 50 may become the bottom, the front face of the article 100 faces directly upward, and the front view can be easily drawn.
