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 recognizing/demodulating circuit compares with each other a demodulated data string including a start bar but excluding an end bar and a demodulated data string including the end bar but excluding the start bar among a variety of demodulated data strings obtained by a scan/convergence optical system scanning a bar code. A total sum of the numbers of digits of the two demodulated data strings is detected, and whether the total sum is larger than the number of digits of the bar code to be read is checked. If larger than the number of digits of the bar code, whether data of overlapped portions of the two demodulated data strings coincide with each other is checked. If coincident, demodulated data corresponding to the whole bar code are synthesized based on the two demodulated data strings.

摘要： A demodulated data storage buffer stores bar width data sets obtained during one scan with laser beams L through a scan optical system. A CPU sequentially demodulates these bar width data sets and stores the demodulated data storage buffer with the bar width data sets as a series of demodulated data strings. The CPU compares respective items of demodulated data with each other that are included in the demodulated data string and preferentially treats, as effective data, the demodulated data based on "continuous reading" and the "block reading". The CPU conceives as noise data the demodulated data logically impossible from a mutual relationship between these items of demodulated data and deletes the same demodulated data.

摘要： A process for reading optical codes includes reading an optical code by irradiating a scanning 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.

摘要： A DMA controller DMA-transfers a bar width data set generated by a bar width counter to an external RAM. The DMA controller simultaneously DMA-transfers the bar width data set written in the external RAM to an internal RAM. An MPU reads the bar width data set written in the internal RAM at a high speed and demodulates the read bar width data set between the reading processes.

摘要： An object of the present invention is to provide a radiation site detector which can detect a position of an incident scintillator with high precision by excluding the effect of Compton scattering. The radiation site detector is provided with a scintillator array having a plurality of scintillators into which a radiation is made incident, and a photodetector for converting scintillations occurring in the scintillators to independent photoelectric conversion signals to output them. A level of each of photoelectric conversion signals output from a specific scintillator to be judged whether the radiation has been incident thereinto, and from a plurality of scintillators around the specific scintillator, is compared with a plurality of threshold values different from one another so as to determine whether the levels are within or outside a window defined by the threshold values. Then, it is judged whether the above specific scintillator is a scintillator into which the radiation has been incident based on the characteristics of a signal pattern obtained in the above comparison.

摘要： The present invention relates to a bar code reading method and a bar code reader applied preferably to POS systems used in the distribution industry. The object of the invention is to achieve an improved reading ratio or a reduced erroneous reading ratio in practical use by evaluating quantitatively the reliability of demodulation data and by performing a coincidence checking plural times only when a large error is recognized. When a reading distortion amount measured is within a predetermined allowable value, data extracted and demodulated from the bar code is judged to be valid, whereby the bar code reading is completed. When a reading distortion amount measured is not within the predetermined allowable value, if the same data from the bar code is extracted and demodulated continuously and at least twice, the same data extracted and demodulated from the bar code is judged to be valid, whereby the bar code reading is completed.
