    摘要： A bar code reader using a high speed scanner, containing: a scanning unit scanning a surface on which a bar code is printed; a bar width detecting unit successively detecting widths of bars; a bar width storing unit storing the widths; an address generating unit generating an address of the bar width storing unit at which each of the widths is to be stored; a fast screening unit determining whether a set of widths successively detected by the bar width detecting unit satisfies a predetermined condition for the set of widths constituting a complete bar code; and a bar code decoding unit reading a set of successive widths from the generated address, and decoding the bar code determined by the complete bar code detecting unit. A type of bar code detecting unit detecting a type of bar code constituted by the detected widths, and an address & type storing unit storing the detected type of bar code, together with information on the generated addresses for the widths of the bar code, may be inserted. The bar code decoding unit contains specific type decoding units for respectively decoding types of bar codes. The bar code decoding unit reads the stored widths from the addresses indicated by the information stored in the address & type storing unit, and decodes the bar code using one of the specific type decoding unit corresponding to the type stored in the address & type storing unit together with the above information.

    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.
