    摘要: A point-of-sale system includes an infinitely adjustable optical scanner for reading bar code symbols, and a terminal operatively connected to the scanner. A bendable, elongated arm is operative for at least temporarily maintaining the scanner in any selected one of an infinite number of adjusted orientations relative to a work surface over which the symbols pass. A hood is mounted on the scanner for preventing overloading of a scanner photodetector. One scan pattern is selected among a plurality of scan patterns to read the indicia.
