摘要： A plurality of bar-code candidate areas are calculated from scan data that is acquired by scanning a bar code. Feature data, which represents a specific feature, is calculated for each of the bar-code candidate areas. The bar-code candidate areas are evaluated based on their feature data to thereby determine a bar-code candidate area that has the highest probability of being a bar code. The specific feature includes any one or more of length of a differential waveform, average energy, and number of peaks in the differential waveform.

摘要： A bar code reader has an arrangement to communicate with a host apparatus. The bar code reader includes a read unit that reads a bar code 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 term of the article has expired based on the term information. A notification unit notifies that the term of the article has expired upon determination by the term expiration check unit that the term of the article has expired.

摘要： A signal obtained by optically scanning a bar code is subjected to differentiation to obtain differential data. Peak-to-peak distances are calculated from the differential data. When a peak-to-peak ΔTx distance is y times of a basic width, frequency f(x,y) will be, f(x,y)=y/ΔTx. A frequency map is prepared from the frequencies calculated. Transition routes in which one frequency each is selected from each of the peak-to-peak distances, are formed. A transition route for which an error in frequencies is the least is taken as the most suitable transition route. An average of the frequencies included in the transition route is taken as a frequency f0 of the basic width.

摘要： An extractor extracts a part that is apparently a bar-code signal from a signal that is subjected to opto-electric conversion. A narrow-band differential processor forms a waveform of an edge by differentiating by using a module frequency. The module point extractor extracts the module point from the waveform. The maximum likelihood judgment processor 5f performs ternarizing based on a maximum likelihood method by using broader information.
