Abstract
In an optical information reading apparatus, a marker beam irradiating unit has a light beam source for emitting a light beam, a diffusing lens for diffusing the light beam emitted from the light beam source, and a collective lens for collecting the light beam diffused by the diffusing means. The marker beam irradiating unit has a pattern forming unit for forming a marker beam based on the light beam collected by the collecting means to irradiate the marker beam. The marker beam has a predetermined beam pattern indicating the reading position of the pickup unit.
