Moreover, the respective line or linear CMOS system is arranged by a fixed number of optical sensors, and can be one-dimensional barcode or two-dimensional barcode by image CCD or image CMOS. However, the invention is called quasi-full. The directional stripper is based on the image CCD or image CMOS, the CCD or linear CMOS interpretation characteristics, and each CCD or linear CMOS has its own corresponding angle, when the one-dimensional barcode is scanned and interpreted, only By rotating the bar code scanner at an appropriate angle, the data can be quickly interpreted, which is not only easy to operate, but also improves the efficiency of understanding the bar code.

Among them, the number of linear CCD or linear CMOS 3023 can be appropriately selected when using linear CCD or linear When the number of CM〇s 3〇23 is small, the number of lines used to capture the one-dimensional bar code 4〇 is also relatively small. Therefore, the dead angle at the time of extraction is also increased, but 疋 'If a linear CCD is used Or when the number of linear CMOS 3023 is too large, the system needs to process more pixels, The reading speed naturally slows down.
