Patent ID: 7611055

Claim:
An optical scanner comprising: a substantially horizontal aperture and a substantially vertical aperture; an optics engine including first and third laser mounts each adapted to mount a laser so that the output beam of the laser is directable through the substantially horizontal aperture; second and forth laser mounts each adapted to mount a laser so that the output beam of the laser is directable through the substantially vertical aperture; first, second, third, and fourth detector mounts; a first laser in the first laser mount for producing a first scanning light beam; a second laser in the second laser mount for producing a second scanning light beam; a mirrored spinner; wherein the first and third laser mounts are located on a first side of the mirrored spinner and the second and fourth laser mounts are located on a second side of the mirrored spinner; a first collector between the first and third laser mounts and the mirrored spinner; a second collector between the second and fourth laser mounts and the mirrored spinner; a first detector in the first detector mount; and a second detector in the second detector mount; first pattern mirrors for receiving the first scanning light beam from the mirrored spinner, for directing the first scanning light beam through the substantially horizontal aperture to produce a first scan pattern, and for directing first light reflected from an item with a barcode label to the mirrored spinner; second pattern mirrors for receiving the second scanning light beam from the mirrored spinner, for directing the second scanning light beam through the substantially vertical aperture to produce a second scan pattern, and for directing second light reflected from the item to the mirrored spinner; and control circuitry for controlling operation of the first and second lasers and the mirrored spinner.
