学装置。[Claim for Utility Model Registration] Laser light emitted from a laser is incident on a polygon mirror, and the polygon mirror scans in a predetermined direction while projecting the laser light onto the barcode label surface. In a barcode optical device for reading a barcode written on a barcode label by making the laser beam reflected by the surface enter the light receiving part through the polygon mirror, the laser beam is reflected by the polygon mirror in the scanning direction. An optical device for a barcode reader, comprising a condensing and reflecting mirror having a concave shape that condenses laser light reflected from each part onto the light receiving section.
