摘要： 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.

摘要： An apparatus for demodulating bar codes is disclosed. In this apparatus of this invention, a distortion quantity calculation unit for calculates a distortion quantity of a bar width of a character to be demodulated by use of bar code data generated by reading the bar codes in which characters are expressed by bar widths. A distortion quantity determining unit determines whether or not a bar width distortion quantity calculated by the distortion quantity calculation unit falls within a range of predetermined values. A first demodulation unit, when determining that the distortion quantity of the bar width falls within the range of the predetermined values, demodulates the character from the bar code data by effecting a first correcting process on the bar width distortion quantity. A second demodulation unit, when determining that the distortion quantity of the bar width does not fall within the range of the predetermined values, demodulates the character from the bar code data by effecting a second correcting process on the distortion quantity of the bar width.

摘要： A bar code data detecting section of a bar code reader scans a bar code twice or more and detects multiple pieces of bar code data, and a decoder decodes the bar code data, Then, a first judging section detects the overlapping part where first decoded data of the decoded in a first scanning trace and second decoded data in a second scanning trace overlap and judges whether or not the overlapping part is composed of a predetermined number of characters. If the overlapping part is composed of the predetermined number of characters, a second judging section judges whether or not the data in the overlapping part of the first decoded data is identical with that of the second decoded data. If the characters are the same, a fourth judging section judges whether or not the character just before the overlapping part of the first decoded data, the character just after the overlapping part of the second decoded data, and the characters constituting the overlapping part are all the same. If they are all the same, a synthesizing section does not combine the first and second decoded data from being generated.

摘要： Demodulated data B containing the whole of a right block and a part of a left block is obtained after demodulated data A containing a start guard bar and based on a division reading process has been at first obtained. When demodulated data C containing an end guard bar and numerical data of three characters is thereafter obtained, a CPU aligns the demodulated data C with modulus 10-OK data obtained by synthesizing the demodulated data A with the demodulated data B on the basis of the end guard bar, and compares tenth through twelfth characters (of the numerical data) of both of data with each other. As a result of this comparison, if the tenth through twelfth characters (of the numerical data) of both of data are coincident with each other, the CPU increments an identical character counter.
