ABSTRACT:
A method and apparatus for reading coded information formed on the lid of a carbonated beverage container. The coded information takes the form of spaced linear code elements, such as indentations, and reading of the information contained in the arrangement of these elements is accomplished through sweeping a laser beam over the elements. In most, but not all, cases, the linear code elements radiate from the axis of revolution of a lid, and the reading of information results from the production of relative rotary movement between the region of beam/lid impingement, and the elements. Preferably, this impingement region is elongated and linear in nature, and sweeps over such code elements in such a manner that, as it passes over each particular element, its long axis substantially coincides with the long axis of the element.
