Abstract
In a static optical bar code reader, a stationary bar code is disposed in operative relationship to a light sensitive charge coupled device. The photosites of the charge coupled device convert light from the contrasting segments of the bar code to an analog voltage. The analog output of the charge coupled device is applied to a circuit which converts it to a digital signal. The digital signal is transmitted to a suitably programmed microprocessor which preferably decodes the digital signal and recovers the information included in the bar code. The output of the microprocessor may be applied to a display, a host computer or some other utilization device.
