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： In a bar-code reader in a POS system, bar-code data is compared with the just previously read bar-code data to detect whether they are identical or not, and if the bar-code data is not identical to the just previously read bar-code data, the bar-code data is transmitted to a station host and, at the same time, a notification is produced to indicate that the bar-code data has been transmitted. If they are identical, and if a double reading prevention timer is not ON, the bar-code data is transmitted to the station host and, at the same time, a notification is produced to signify that the bar-code data has been transmitted; on the other hand, if the double reading prevention timer is ON, the bar-code data is discarded, and a notification signifying the discarding of the data is produced with different sounds from that used for the transmission notification. When treading a bar code attached to a product, this feature allows the operator to know what to do next when the same product as the immediately previous one is scanned during the ON period of the double reading prevention timer activated to prevent double reading of the same product. This alleviates an operator's stress when performing the reading operation.
摘要翻译：在POS系统中的条码阅读器中，将条形码数据与先前读取的条形码数据进行比较，以检测它们是否相同，如果条形码数据与先前读取的条形码数据不一致条形码数据，条形码数据被发送到站主机，并且同时产生指示条形码数据已被发送的通知。如果它们相同，并且如果双重读取防止定时器不为ON，则将条形码数据发送到站主机，并且同时产生指示条形码数据已被发送的通知; 另一方面，如果双重读取防止定时器为ON，则条形码数据被丢弃，并且产生与用于发送通知的声音不同的声音的表示丢弃数据的通知。当附加到产品上的条形码时，该功能允许操作者在激活的双重读数预防定时器的ON期间扫描与之前的相同产品在下一步做什么，以防止双重读取相同产品。这在执行读取操作时减轻了操作者的压力。

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.
