    摘要: The bar code reading apparatus for decoding a character from a bar code (10) comprises a reader (20) for reading a bar code (10) expressing a plurality of characters, and a CPU (70) for decoding the characters according to a result of reading by the reader. A ratio between a character length (C Y ) of an already decoded character (E2) and a length (C Z ) of a character (E7) to be decoded is calculated. When this ratio is greater than a threshold value, a black bar width (B 1 ) and black bar width (B 2 ) are corrected according to a reference black bar width (X). The CPU decodes the character (E7) to be decoded according to the corrected black bar width (B 1 ) and black bar width (B 3 ).

    摘要: The present invention introduce a bar code reader capable of inferring data coded into one character failing in demodulation when one character can not be demodulated. The CPU demodulates the data obtained by reading bar code for each data character. Concerning the data character failing in demodulation, bar width data for four bars before demodulation is stored in the temporary saving buffer. When 11 data characters are successful in demodulation, the CPU calculates back the modulus 10 check based on the demodulated data corresponding to 11 data characters, and infers a value of the demodulated data corresponding to the data character failing in demodulation. The CPU, when the data character failing in demodulation is contained in the left data block, infers an ODD/EVEN configuration of the demodulated data corresponding to the data character failing in demodulation based on five pieces of demodulated data corresponding to data characters successful in demodulation in the left data block.

    摘要: A method of the invention reads a bar code (7) based on bar-code data obtained by scanning the bar code (7) with light (L2). The method includes the steps of a) obtaining bar-code data, b) obtaining a sum of bar-data widths with respect to a predetermined number of bar data provided in at least one of a preceding portion and a following portion of the bar-code data, c) repeating the steps a) and b) once to obtain another sum, and d) making a comparison of the sum with another sum. The methods further includes a step of accepting the bar-code data as valid data when a result of the comparison satisfies a predetermined condition.

    摘要: A bar-code reader has an optical scanner (2) which optically scans a bar code (1) to obtain signal strength of light reflected from black bars and white bars of the bar code (1). An extracting unit (5a) then extracts edge data, which includes a plurality of edges and the signal strength of which changes corresponding to a change from a black bar to a white bar and vice versa, and an edge-emphasizing unit (5f) emphasizes edge data of an edge that satisfies a predetermined condition. A judgment unit (5h) is then used to make a ternary judgment of each edge based on the edge emphasized to obtain a ternary result, and a decoder (5i) decodes bar-code characters from the ternary result.

    摘要: A bar code reader (100) is arranged to communicate with a host apparatus (200). The bar code reader includes a read unit that reads a bar code (50) attached to an article, and outputs bar code information corresponding to the read bar code; a term information acquisition unit that acquires term information included in the bar code information; and a term expiration check unit that checks whether the shelf life of the article has expired based on the term information. A notification unit notifies that the shelf life of the article has expired upon determination by the term expiration check unit to the host apparatus (200). By performing its own expiration check, the bar code reader reduces the load on the host apparatus.

    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 (SGB) and based on a division reading process has been at first obtained. When demodulated data C containing an end guard bar (EGB) and numerical data of three characters is thereafter obtained, the demodulated data C is aligned 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 (EGB), and compares the tenth through twelfth characters (of the numerical data) of both of the data with each other. As a result of this comparison, if the tenth through twelfth characters (of the numerical data) of both of the data are coincident with each other, an identical character counter is incremented.
