The invention relates to a bar code scanning device and belongs to the technical field of laser bar code scanning. The bar code scanning device comprises a housing, a trigger, a button, a glass window, a distance indicator light, a bar code scanning module, an LED indicator light, a buzzer, a main board and a power supply interface. The trigger, the glass window, the power supply interface and the distance indicator light are installed outside the housing; the trigger is connected with the button; the button is fixedly connected with the main board; and the power supply interface, the bar code scanning module, the LED indicator light, the buzzer and the distance indicator light are connected with the main board. The distance indicator light connected with the main board can remind the distance between a tested object and a bar-code scanner clearly; and when the distance is too far away, the indicator light is green, and when the distance is too short, the indicator light is red, so that a tester can adjust the distance between the tested object and the bar-code scanner according to the showed distance, test time can be saved, the tester is allowed to judge whether to approach to or keep away from the tested object easily, scanning time is reduced greatly and scanning efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of laser barcode scanning, in particular to a barcode scanning device. Background technique [0002] A barcode is a graphic identifier used to express a set of information by arranging multiple black and white bars of different widths according to certain coding rules. A common barcode is a one- or two-dimensional pattern of black and white bars of widely varying emissivity. Barcodes can contain many information such as the place of manufacture, manufacturer, commodity name, price, production date, book classification number, mail start and end location, category, date, etc. fields have been widely used. To convert the barcode compiled according to certain rules into meaningful information that workers can read directly, it is necessary to read the information contained in the barcode through a barcode scanning device. [0003] Any code reading device has a specific effective distance and depth of field s...
