Structural Part Of The Barcode Scanner

Bar code scanners are often called bar code scanners / readers. They are devices used to read the information contained in bar codes. They can be divided into one-dimensional and two-dimensional barcode scanners. The structure of a barcode scanner is usually as follows: 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 barcode symbol through the optical system. The reflected light is imaged on the photoelectric converter by the optical system, and interpreted by the decoder as a digital signal that the computer can directly accept. Divide one or two-dimensional barcode scanner classification. Can also be classified as: CCD, full-angle laser and laser handheld barcode scanner.

Bar code scanners are also called bar code readers, bar code scanners, and laser bar code scanners. They are widely used in supermarkets, logistics express, and libraries to scan the bar codes of goods and documents.

The laser scanner scan window transmission mirror uses special toughened material, which has a smooth light transmittance and a long depth of field. The overall plastic must be odorless, high temperature, corrosion resistant, easy to scrub, and easy to operate.
