Abstract
An optical code scanning reader comprising laser beam generating elements focused at different distances from an optical receiver element having an optical axis and a photoreceiver element having a preselected photosensitive area; the laser beams travel along a minimum of two different optical paths in the reader and at least one of the two optical paths is offset in respect to the optical axis; the value of the offset (H ) is preselected in such a way that the quantity of light diffused by the code which reaches the photosensitive area for each beam attains a preselected value.
