<p>PROBLEM TO BE SOLVED: To obtain the visibility of pixels with a simple constitution by integrating picture display setting parts in a casing and using at least four shafts and four eccentric bolts. SOLUTION: An LCD phototube 3 holds all internal function groups and has a casing capable of fixing the phototube 3 in a video equipment. The phototube 3 is coupled with a substrate 1 for the video equipment with the aid of a sheet-like metal blacket 2. In order to adjust four shafts, the blacket 2 and the phototube 3 are coupled with each other by using guide pins and fixing screws annexted to eccentric bolts. Since the blacket 2 is guided along an optical axis 11 by using the functions of guide pins 7 clamped on the substrate 1, the visibility of pixels can be set up. After setting up the visibility, the blacket 2 is fixed on the substrate 1 at least by one clamp screw 8.</p> |
