More Information
Summary:The utility model belongs to the technical field of bar code reading, and discloses bar code reading equipment, which comprises a shell 1, an imaging module 2, a lighting module 3, an extinction plate 4, a beam splitting lens 5 and a protective transparent screen 6. The imaging module 2 and the lighting module 3 are respectively located at two sides of the light splitting lens 5, the light extinction plate 4 is right opposite to the lighting module 3, and the light splitting lens 5 and the protective transparent screen 6 form an included angle of 45 degrees. The design that the single light source is matched with the light splitting lens is adopted, the functions of a focusing lamp and an illumination light supplementing lamp are achieved at the same time, the equipment power consumption is reduced, the equipment size is reduced, the center of a formed light spot and the center of an imaging module are consistent and do not deviate, pattern edges are clear and high in brightness, a reading area does not have
