A combiner positioning system for a head-up display is provided. As a result, the cable will not stick straight out from the back of the drive and the drive footprint is also reduced. Rotating shafts of the pair of shaping rolls are cooperatively coupled with a rotational driving means through eccentric couplings. The stored program can be deleted at a desired time. In the step of inspecting the conductive pattern and the foreign matter, a reflectance of the table reflected light is in a range of 25 to 55%, and a reflectance of the foreign-matter reflected light is in a range of not more than 10%. The method further includes photolithographically defining the predetermined pattern in the carbon-containing hard mask layer, and etching the target layer in the presence of the hard mask layer.
