Abstract
A hologram scanner includes a rotatable hologram disk on which a plurality of hologram lenses are arranged circumferentially, and a light beam guide mechanism for successively shifting irradiation regions in a predetermined direction with respect to the direction of rotation of the hologram disk, to apply a light beam successively to the hologram lenses on the hologram disk, so that the scanning of a reading window with the light beam is effected in all directions with high density. The hologram scanner is employable as a bar code reading device in a POS or UPC system.
