摘要： A proximity sensor receives light beams reflected from a goods. A proximity sensor control unit determines that the goods exists when a light quantity of the reflected light received by the proximity sensor exceeds a determination threshold value. The determination threshold value increases as elapsed time since the bar code was read last time becomes longer, and, as a result, a detection sensitivity decreases. A CPU restores a duty of irradiation of the laser beam back to 100% and resumes rotations of a motor for driving an operation optical system when the proximity sensor control unit determines that the goods exists.

摘要： A bar code reader decodes a bar code in different directions if the bar code contains special characters whose bar widths have been corrected. The bar code reader compares the decoded results in the different directions with each other, to improve the bar code reading reliability. If the decoded results agree with each other, the results are accepted, and if not, they are discarded.

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 process for reading optical codes includes reading an optical code by irradiating a scan ing beam onto an optical code and detecting a reflected beam of the scanning beam from the optical code. A determination is made if the optical code and an optical code reader are moving relative to each other, and data of the optical code are invalidated if it is determined that the optical code and the optical code reader are moving relative to each other, and data of the optical code are validated if it is determined the optical code and the optical code reader are not moving relative to each other.
