Problems solved by technology

[0003] In many applications, the ambient light for barcode scanning is insufficient, and the barcodes on different media or on different surfaces have different contrast or reflectivity, which poses new challenges for code reading equipment
Some additional auxiliary lighting devices may cause code reading failure due to reflection or flare

Abstract

A scanner includes: a shell, an acquisition device arranged in the shell, and a light supplementing device arranged on the shell, arranged at one end of the shell and arranged corresponding to the acquisition device. A scanning window corresponding to the acquisition device is arranged on the shell; and the light supplementing device comprises a light supplementing light source and a transparent or semitransparent light supplementing and transmitting part, wherein the light supplementing light source is arranged at one end of the shell and corresponds to the scanning window, and the light supplementing and transmitting part is arranged on the shell and corresponds to the light supplementing light source. The light supplementing and transmitting piece comprises a light transmitting main body part formed by connecting multiple sections of curved surfaces or cambered surfaces, and a light transmitting mounting part formed by extending the light transmitting main body part. According to the scanner, the light supplementing device is arranged for supplementing light, and the line light source emitted by the light supplementing light source is subjected to optical refraction and diffusereflection through the multiple sections of curved surfaces or cambered surfaces arranged on the light transmitting main body part to form the surface light source, so that the light supplementing area is enlarged, light supplementing can be better carried out on the scanning window, and the light supplementing effect is improved.

Description

technical field [0001] The invention relates to data acquisition equipment, in particular to a scanner. Background technique [0002] The scanner in the scanner is used to scan and identify graphic identifiers such as one-dimensional codes and two-dimensional codes. Using optical principles, the contents of the graphic identifiers are decoded and transmitted to computers or other processing devices through communication lines or wireless communication. At present, it is widely used in various commercial cash registers, express logistics, warehousing and transportation, intelligent manufacturing and other fields, and has become an important part of the IoT ecosystem. [0003] In many applications, the ambient light for barcode scanning is insufficient, and the barcodes on different media or on different surfaces have different contrast or reflectivity, which poses new challenges for code reading equipment. Some additional auxiliary lighting devices may cause code reading fai...
