As shown in FIG. 4C, the resolution of the image pattern 235 will be higher than the resolution of the image pattern 233. Therefore, the resolution of the line pattern 232 can be set and the resolution of the original image pattern 233 of the line pattern 232 can be reduced or enlarged correspondingly after the scaling of different optical lenses 254, so that the same line pattern 232 can generate different resolutions. Degree image pattern 233, 234, 235 ° Please refer to Figures 2 and 3, because the test chart 230 is made by printing the line pattern 232 on the surface of the test chart 230 in a printed manner, so that the line pattern 232 will Limited by the limitation of printing production ', its resolution cannot be further improved. However, the multi-resolution adjusting fixture 200 of the present invention uses the optical lens 254 to reduce a high-resolution line pattern 232, so that it can produce a higher resolution. The image pattern 235 is an optical scanner that provides ultra-high resolution for commissioning. Please refer to FIGS. 5A and 5B at the same time, which are exploded and combined diagrams of the adjustment structure of an optical lens of the present invention, respectively. In order to adjust the depth of field of the optical lens 254, as shown in FIG. 5A, the optical lens 254 is composed of an upper lens barrel 255, a lower lens barrel 257, and at least one lens 259. And has a plurality of oblique holes 256, which are respectively distributed on the side wall of the upper lens barrel 255, and the lower lens barrel 257 has a plurality of convex posts 258, which respectively correspond to the oblique holes 256 and protrude from the side walls of the lower lens barrel 257, The lens 259 is configured to be embedded at one end of the lower lens barrel 259. As shown in FIG. 5B, when the inclined hole 256 of the upper lens barrel 255 is fitted with the convex column 258 of the lower lens barrel 257, if the position of the convex column 258 is adjusted obliquely along the arrow, the upper lens barrel 255 and the lower lens The lens barrels 257 move vertically relative to each other, and then plummet ---------------- (Please read the note on the back?

Description of the invention (1) Move the lens 259 straight up and down to adjust the depth of field of the optical lens 254. Therefore, the optical lens 254 used in the present invention can adjust the distance between the lens 259 and the line pattern of the optical lens 254 through the similar adjustment structure, that is, the structure of the corresponding oblique hole 256 and the convex column 258 or other adjustment structures. Distance of the optical lens 254 to adjust the depth of field of the optical lens 254. In summary, the multi-resolution adjusting jig of the present invention has the following advantages: (1) The multi-resolution adjusting jig of the present invention can improve the problem of wear and scratch caused by the replacement of the conventional test chart, and a lot of differences Resolution jigs are inconvenient for storage and management. (2) The multi-resolution adjusting jig of the present invention is configured by at least one conversion base and multiple optical lenses on the adjustment jig, and adjusting the conversion base to switch the required optical lens, so that the same adjustment jig can correspond to Line patterns with different resolutions are provided to greatly reduce the commissioning cost of the optical scanner. (3) The multi-resolution adjusting fixture of the present invention uses an optical lens to reduce a high-resolution line pattern, so that a higher-resolution image pattern can be generated to provide an ultra-high-resolution optical scanner as an optical For commissioning between system components. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and retouching without departing from the spirit and scope of the present invention. The scope of protection of the invention shall be determined by the scope of the attached patent application. (Please read the notes on the back before filling this page) Binding:
