ーコード読取装置。In a barcode reading device comprising a laser beam scanning means, a laser beam detection means, and a barcode demodulating means, the device includes a buffer memory for temporarily storing read symbol information, and a newly read barcode symbol stored in the buffer memory. Comparison means for comparing with stored symbols, a gate circuit that prohibits barcode signal output if a newly read barcode symbol is the same as the symbol stored in the buffer memory, and canceling the prohibition of barcode signal output. A barcode reading device characterized by having a reset button.
