[0003] The diffuser of the existing barcode scanning reader is a lens with a flat surface. Therefore, when the light passes through the diffuser and is refracted, the brightness of the light at the center is stronger, while the brightness of the light at the sides is smaller. The fan-shaped light source, the uneven light source cannot completely scan the code area on the barcode symbol, resulting in poor accuracy of barcode identification

The invention discloses a bar code scanning reader comprising a housing and a reader arranged in the housing; the housing comprises an upper housing and a lower housing; the upper and lower housings respectively comprise a scanning portion and a handle portion formed by extending from the scanning portion; a receive room used for containing the reader is arranged in the scanning portion and handle portion of the lower housing, and the scanning portion is provided with a projection port; the reader comprises an electronic circuit device and an optical assembly; the electronic circuit device is arranged in the receive room of the handle portion; the optical assembly comprises a diffusion lens and an illuminating part group electrically connected on the electronic circuit device; the diffusion lens is configured on a light projection path of the illuminating part. The illuminating part can fully scan the bar code symbol, thus improving the bar code discrimination accuracy.
Description
technical field [0001] The invention relates to a reader, in particular to a barcode scanning reader. Background technique [0002] With the improvement of optical coding technology, the barcode system has replaced the complicated manual input method, and is widely used in various fields, and has the advantages of convenient control of goods and materials, document processing and filing, and rapid judgment of commodity prices. [0003] The diffuser of the existing barcode scanning reader is a lens with a flat surface. Therefore, when the light passes through the diffuser and is refracted, the brightness of the light at the center is stronger, while the brightness of the light at the sides is smaller. The fan-shaped light source, the uneven light source cannot completely scan the code area on the barcode symbol, resulting in poor accuracy of barcode identification. In addition, the fixed-pitch and wavy-shaped diffuser still has some dark areas after the light is refracted by...
