面(象を利用で牙る保障がない。Above all, there are individual differences in the produced projection lenses, and in particular, the breaking power of the image has various values in any direction within the screen. Therefore, if the projection lens is screwed to the lens plate using the mounting flange as described above, the part of the projection lens that has the best disintegration force will be exposed to the strip-shaped surface that passes through the slit. .

In this method, a screw hole is provided in a mounting seat formed with a pair of "V"-shaped receiving surfaces that receive the curves of a cylindrical lens that rotates around the optical axis, and the cylindrical lens is held in the screw hole using a holding band. We propose to utilize the high resolution (elephant force direction) of the lens for imaging the band-like 1Ilj?elephant by fixing it to .
