Abstract
A scanning reader of an optical code placed on a front wall of an article in movement comprises generators that form at least one first and one second light beam lying on planes inclined by a first and by a second prefixed angle (.alpha., .beta.) with respect to the front wall so as to explore a first and a second area of the front wall by at least one first and one second scanning line and read the optical code within an overall distance range, along the direction of forward movement of the article, greater than the useful range of reading distance that can be reached by one light beam only.
