ABSTRACT:
A bar code reader is provided which is designed to read a bar code carrying information according to a combination of lengths of bars of the code. The bar code reader includes a light source for radiating light onto the bar code, a light gathering system for gathering the light reflected from the bar code to compress the gathered light at a preselected rate in a lengthwise direction of the bars, a photoelectric converter, responsive to the light compressed by the light gathering system, for providing a signal having a level corresponding to a degree of intensity of the compressed light, and a bar code information reading unit, responsive to the signal from the photoelectric converter, for reading the information carried by the bar code. With this arrangement, the bar code may be read in a one-time scanning operation completely regardless of a type of image sensor: one-dimensional or two dimensional sensors.
