Abstract
A bar-code reader is easy to use and has an optical system that is easy to position and replace. The bar-code reader is used for a POS system. The bar code reader has a laser source for emitting a laser beam, a scan unit for scanning a bar code with the laser beam according to a predetermined scanning pattern, a window for emitting the laser beam from the scan unit, a condensing unit for condensing reflected light returned from the bar code through the window and scan unit along the route the laser beam traced, a photosensor for detecting the condensed light and providing an electric signal in proportion to the intensity of the detected light, and an emission-condensing unit incorporating the laser source, condensing unit, and photosensor, which can be easily and correctly mechanically installed.
