摘要： Device (100) for reading coded information, comprising a first optical group (10) including a first light source and first focusing means in optical alignment with said light source along an optical axis (X), and at least one further optical group including a further light source and further focusing means in optical alignment with the further light source along an optical axis (X1) parallel to the optical axis (X). The first optical group (10) and the further optical group (20) are housed in a single one-piece block (50) obtained through a single mechanical processing that, preferably, is a machine tool processing. The number of components of the reading device is thus reduced and the calibration operations necessary to achieve the desired optical alignment between light sources and with the respective focusing means are simplified and automated. Consequently, the costs of material and qualified workers are reduced, as is the time needed to calibrate the reading device.

摘要： A low profile tri-aperture optical code scanner and operating method are presented. The scanner includes three scanning apertures and a front and a rear low profile housing component. Each housing component includes a scanning aperture tilted toward a point about the center of the scanner. A third scanning aperture is located in a horizontal top surface of the scanner. The low profile housing elements allow an operator to scan items by standing either on the front side or the rear side of the scanner. When used in a convertible point of sale terminal, a cashier operates the scanner from the front side of the scanner when the terminal is in the assisted mode and a customer operates the scanner from the rear side of the scanner when the terminal is in the self-service mode.
