Bar code symbols have become widely used in many commercial fields such as, point-of-sale (POS) stations in retail stores and supermarkets, inventory and document tracking, and various data control applications. A barcode scanner is an apparatus which applies light such as a laser beam emitted from a light source toward a bar code portion and reads the bar code from an electronic signal obtained by receiving its reflected light. In bar code scanning systems, a light beam is scanned across a bar code symbol, and reflected light is collected, using either retroreflective or non-retroreflective light collection. Barcode scanners typically employ decoding circuitry to interpret the signals produced by a photodetector receiving the reflected light from the bar code symbol. To meet the growing demands, bar code readers of various types have been developed for scanning and decoding bar code symbol patterns and producing symbol character data for use as input in automated data processing systems. Bar code scanners generally fall within one of two types, laser scanners and contact scanners. A laser bar code reader is composed of a laser beam generating light source, a laser beam shaping optical system, a scanning optical system, a signal light detecting optical system, a waveform shaping circuit, and a bar code decoding circuit. The laser light from which is collimated and focused to produce a scanning beam, The scanner scans its emission output on barcode information by a scanning mirror, reads intensity of a reflected light from a barcode by a photodetector, so that a barcode signal corresponding to the barcode information is obtained. CCD type bar code optical scanners commonly have a LED light source, a CCD (charge coupled device), and a processing circuit.  A portion of the light which is reflected from the coded symbology is detected by the CCD linear sensor and converted into an electrical signal which is the basis for a digital image of the coded symbology that has been scanned. Contact readers are light-weight and easy to use, but require substantially direct contact or placement of the reader on the symbol to enable the symbol to be properly read.
