Laser bar code scanner with window-reflection prevention structure



The utility model provides a laser bar code scanner with a window-reflection prevention structure, which comprises an upper side cover, a lower side cover, a circuit board, a light source, a window, a scanning mirror, a photoelectric converter and a condenser. A rid plate is arranged on the upper side cover and arranged on a propagation path of reflected light thereof according to an angle between the window and light emitted by the light source so as to block a path of the reflected light propagated to the scanning mirror, so that noise caused by decoding of reflected light of the window to the photoelectric converter can be avoided. By the laser bar code scanner with the window-reflection prevention structure, light reflected by the window can be prevented from being received by the photoelectric converter effectively, noise interference during decoding is avoided, and decoding performance of a bar code scanner is improved.
