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.

摘要： A POS system comprises a host computer providing a centralized control over a plurality of scanners, and a printer for printing a batch setting bar code or the like. A CPU of the scanner reads the changes in the setting from its own memory when it receives a first transmission request command and then transmits the data to the host computer as a first batch setting data. From this first batch setting data, a first batch setting bar code is generated. When this first batch setting bar code is read using the reader of the scanner whose setting has not been changed, the setting in the memory of this scanner is changed to the setting represented by the first batch setting data. Thus, setting in a plurality of scanners can speedily and accurately be changed.

摘要： A bar code reader for reading a bar code 30 composed of a plurality of white bars and a plurality of black bars, includes a generating unit 8 for generating bar width values respectively showing a width of the read bars, a judging unit 12 for judging based on the bar width values whether or not the read bar code satisfies a predetermined standard condition, and a converting unit 12 for converting the read bars into a plurality of bars in which a black-and-white-inverted bar is interposed between the conversion-target color bars. If the judging unit judges that the bar code does not satisfy the predetermined standard condition, the converting unit converts any one of the white and black bars constituting the bar code, and thereafter the judging unit makes a re-judgement. The bar code reader is capable of demodulating the bar code which has been abnormally read by presuming and compensating the bars read apparently as a single bar to a plurality of bars.

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.
