載のバーコードリーダ。[Claims for Utility Model Registration] (1) A light source consisting of a semiconductor laser diode that emits laser light, and a rotatable light source that is disposed on the optical axis of the laser light and reflects the laser light onto a barcode reading surface. The scanning mirror includes a scan mirror and a light receiving unit that receives reflected light from the barcode reading surface, and the laser beam is directly reflected on the reflective surface of the scan mirror to irradiate the barcode reading surface, and A barcode reader characterized in that the barcode is read using a repetitive signal obtained by the light receiving unit by rotation of a mirror. (2) The barcode reader according to claim 1, wherein the light source has a cylindrical lens on its front surface that spreads the laser light in a width direction perpendicular to the scanning direction of the barcode. (3) The barcode reader according to claim 1, wherein the light source includes a visualization unit made of an LED that emits visible light in accordance with the path of the laser beam.
