Guangzhou State Association | one-dimensional scanner | scanner provided by the Canton State Association. We are Guangzhou City State Association Information Technology Co., Ltd. (www.gzdb899.com) located: Guangzhou specializes in: cash register, scanner, bar code machines, management software, a small ticket machines, cash registers, shredders barcode scanner principles and types of barcode scanner is a device for reading the information contained in the bar code, bar code readers structure is usually the following parts: a light receiving device, a photoelectric conversion unit, decoding circuitry, computer interface. Their basic working principle is: the light emitted by the light source through the optical system is irradiated to the bar code symbol above the light is reflected back through the optical system image on the photoelectric converter, to produce an electrical signal 808 laser scanner, signal after amplification circuit After generating an analog voltage one-dimensional scanner, it is irradiated onto the bar code symbol is the reflected light is proportional to the back, and then after filtering, shaping, forming a corresponding analog signal square wave signal, the decoder can be directly interpreted as computer received digital signal. Common barcode scanner typically uses the following three techniques: light pen, CCD, laser, they have their own advantages and disadvantages, no one scanner can have an advantage in all respects. 4600 scanner optimal solution is a two-dimensional image scanner radio scanner, with excellent performance, low price, shape ergonomically designed to meet the application needs a variety of occasions. 4600 scanner optimal solution in product performance highlights include: high cost: low prices, superior performance; lightweight, user-friendly design: Scan rapid and sensitive, beautiful appearance and smooth, comfortable feel natural, ergonomic design; multiple scan mode : supports both conventional manual mode, and also supports fixed scan mode for automatic detection and automatic scanning; advanced decoding technology: the introduction of top international decoding technology to accurately interpret the standard one-dimensional and two-dimensional bar code; reliable data acquisition capabilities: Supports all Standard one-dimensional and two-dimensional symbologies mainstream, but also mobile phones and other electronic screens can be read two-dimensional code; protect future investments: a low price to provide two-dimensional code scanning capabilities, a piece of equipment to meet current and future business needs of barcode scanning .
