Method and apparatus for optically reading information attached to a target
In an apparatus, a collimated-beam irradiating unit irradiates on the target a substantially collimated beam with a size thereon. A first pickup unit causes the photodetector to pick up through the imaging optics a first image of the target while the substantially collimated beam is being irradiated on the target by the collimated-beam irradiating unit. A measuring unit measures size information indicative of the size of the collimated beam being irradiated on the target based on the picked-up second image. A distance determining unit determines a distance between the apparatus and the target based on the measured size information of the collimated beam.
