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.
摘要翻译：接近传感器接收从商品反射的光束。当接近传感器接收的反射光的光量超过确定阈值时，接近传感器控制单元确定商品存在。判定阈值随着从上次读取条形码的时间变长而增加，结果检测灵敏度降低。当接近传感器控制单元确定存在商品时，CPU将激光束照射的占空比恢复到100％，并恢复用于驱动操作光学系统的电动机的旋转。

摘要： A bar-code reader having a photoelectric conversion unit for converting reflected light from a bar code into an electric signal and a changing point detecting unit for detecting, from the electric signal generated by the photoelectric conversion unit, a changing point at which a white stripe is changed to a black stripe in the bar code wherein the bar code is read based on a plurality of changing points detected by the changing point detecting unit. The bar-code reader includes a determination unit for determining, based on measurement of a distance between changing points, whether a changing point is detected as a true changing point at which a white stripe or a black stripe is changed to a black stripe or a white stripe in a bar code or as a false changing point; and a correcting unit for correcting the changing point detected as the false changing point to the true detecting point based on the changing point determined as the true changing point.
