とするバーコード読取装置。 In a barcode reading device having a reading means for reading a barcode and a barcode determination means for determining a barcode based on the reading output of the reading means, a signal number counting means for counting the number of signals transmitted from the reading means; barcode storage means for storing the signal transmitted from the reading means; reading completion detection means for detecting the end of reading of the barcode signal; and a standard for outputting a reference value at least equal to the number of signals constituting the barcode signal. a value generating means; a means for comparing the number of barcode signals outputted from the reference value generating means with a count value of the signal number counting means; and a signal stored in the barcode storing means based on the comparison result of the comparing means. A readout means for transferring the signal to the barcode determination means is provided, and when the completion of reading of the barcode signal is detected, the number of read signals is compared with a reference value, and based on the comparison result, it is determined whether or not the signal can be transferred to the barcode determination means. A barcode reading device that controls.
