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 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.

The bar-code reader scans a bar-code with electromagnetic radioactive rays and then extracts data regarding a bar-width thereof based on the reflected rays; demodulates the bar-width data and creates the demodulated data; judges the presence or absence of a bar-code reproducible combination in the demodulated data and judges. the type of combination when the reproducible combination exists; and synthesizes the demodulated data or the character forming the demodulated data according to the type of combination. The bar-code reader and bar-code reading method can be applicable to scanners such as POS systems used in supermarkets, distribution industries, and the like.
