Barcode scanner, also known as bar code reader, bar code scanning gun, bar code scanner, bar code scanning gun and bar code reader. It is a reading device used to read the information contained in the bar code. Using the optical principle, the content of the bar code is decoded and transmitted to the computer or other equipment through data line or wireless. It is widely used to scan the bar code of goods and documents in supermarkets, logistics express, libraries and so on.
Industrial mobile computer's product introduction
Bar code scanner, also known as bar code scanning gun / reader, is a device used to read the information contained in bar code. It can be divided into one-dimensional and two-dimensional bar code scanners. The structure of bar code scanner is usually the following parts: light source, receiving device, photoelectric conversion component, decoding circuit and computer interface. The basic working principle of the scanning gun is: the light emitted by the light source shines on the bar code symbol through the optical system. The reflected light is imaged on the photoelectric converter through the optical system, and interpreted by the decoder as a digital signal that can be directly accepted by the computer. Except for one and two-dimensional bar code scanner classification. It can also be classified as CCD, full angle laser and laser handheld bar code scanner.
Pda barcode scanner's classification
Bar code scanner, also known as bar code reader, bar code scanning gun and laser bar code scanner, is widely used to scan the bar codes of commodities and documents in supermarkets, logistics express, libraries and so on.
The light transmitting mirror of the scanning window of the laser scanner adopts special toughened materials, with smooth light transmittance and far-reaching scenery. The overall plastic needs to be free of odor, high temperature resistance, corrosion resistance, easy scrubbing and convenient operation.
Pda barcode scanner's four technologies
Ordinary bar code readers usually use the following four technologies: light pen, CCD, laser and image red light.
