摘要： A bar code reader includes a laser source for emitting a laser beam, and a scan device for scanning a bar code with the laser beam according to a predetermined scanning pattern. A window passes the laser beam from the scanning device toward the bar code which is in the vicinity of the window. A condenser condenses reflected light return from the bar code through the window and scanning device along the route traced by the laser beam. A photosensor detects the condense light and provides an electric signal which is proportional to the intensity of the detected light. A main body accommodates the laser source, the scanning device, the window, the condenser, and the photosensor. A cover is attached to the main body, and has an opening corresponding to the window. A buzzer is provided, to create a buzzing sound which resonates in a space formed between the main body and the cover.

摘要： A bar-code reader includes a laser source for emitting a laser beam, and a scan device having reflecting surfaces for scanning a bar code with the laser beam according to a predetermined scanning pattern. A window passes the laser beam from the scan device toward the bar code. A condensing device is provided for condensing reflected light returned from the bar code which passes through the window and is reflected by the reflecting surfaces of the scan device along the route traced by the laser beam. A photosensor is provided for detecting the condensed light and for providing an electric signal in proportion to the intensity of the detected light. A replaceable emission-condensing unit incorporates the laser source, the condensing device, and the photosensor except the scan device and the window, to be mechanically correctly installed.
