[0016] 2. The utility model is provided with a pressing switch for turning on the scanner body at the handle of the scanner body through the arrangement of a display screen, a controller, a photoresistor, a distance measuring sensor and a fill light. The pressing switch, the photoresistor and the fill light are connected in series. The photoresistor can change the resistance according to the brightness of the light in the environment. When the light in the environment is dim, the resistance of the photoresistor decreases. At this time, when the user presses the switch to scan the code, the fill light will also be energized, thereby filling the light for the barcode to avoid the failure of scanning due to too dark light. At the same time, when the user presses the scanning switch, the distance measuring sensor can also measure the distance of the scanned object. A comparison operation module and a processor module are arranged inside the controller. When the user scans the code too far or too close, words will be displayed on the display screen to require the user to scan the code slightly closer or slightly away from the product.
