Abstract: PURPOSE: A barcode reader is provided to improve user convenience by including short distance and long distance barcode recognition functions at the same time. CONSTITUTION: An optical system (130) includes a mirror, emits light from a light output unit (110) to a barcode, and emits the light reflected from the barcode to a light receiving unit (120). A control unit (140) controls the operation of the light output unit includes an operation control unit (141) processing an optical signal received from the light receiving unit and a signal processing unit (142) performing barcode recognition. The optical system includes a path selection mirror (131) for forming paths of the light reflected from the barcode and recognizing the barcode from one selected from the paths.
