SOLUTION: A measuring tape 3 is installed on a horizontal plate part 2a of a base 2 formed in an L-shaped section, and a laser radiator 5 is installed at the tip of a tape-like scale 4 of the measuring tape 3. Subsequently, the horizontal and vertical plate parts 2a, 2b of the base 2 abuts on the horizontal and vertical frame plates (e), (c) of a form (b), and a fixed element body 16 is passed through a support pipe 15 to be driven in the horizontal frame plate (e), whereby the base 2 is fixed with the reference line CL and the laser axis LC parallel to each other. Next the scale 4 is drawn out to confirm the scale visually from above the horizontal piece part 8a of a guide 8, simultaneously the laser radiator 5 is lowered to a preset desired depth, and the flat surface 11 of the main body 10 is fixed to the vertical frame (c). Thus, inking is applied to a point (horizontal height position) of the vertical frame part (c) of both sides to which laser radiated to the front and the back from the laser light emitting part 13 is applied.
