Abstract
In a bar-code reader in a POS system, bar-code data is compared with the just previously read bar-code data to detect whether they are identical or not, and if the bar-code data is not identical to the just previously read bar-code data, the bar-code data is transmitted to a station host and, at the same time, a notification is produced to indicate that the bar-code data has been transmitted. If they are identical, and if a double reading prevention timer is not ON, the bar-code data is transmitted to the station host and, at the same time, a notification is produced to signify that the bar-code data has been transmitted; on the other hand, if the double reading prevention timer is ON, the bar-code data is discarded, and a notification signifying the discarding of the data is produced with different sounds from that used for the transmission notification. When treading a bar code attached to a product, this feature allows the operator to know what to do next when the same product as the immediately previous one is scanned during the ON period of the double reading prevention timer activated to prevent double reading of the same product. This alleviates an operator's stress when performing the reading operation.
