Steven Joel Hammer - Lilburn GA

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06K 710

US Classification:

2354624, 359216

Abstract:

Techniques for arrangement of components in a bar code scanner so as to make efficient use of space are described. A scanner includes a single scan window, a laser source for producing a laser beam, a rotating optical spinner to reflect the laser beam to produce a scan beam and a collection of fixed mirrors to reflect the scan beam in order to give it a desired optical length and to direct it out of the scan window. In order to make efficient use of space within the scanner, the spinner comprises a multifaceted hollow reflector, and a collector mirror is placed within a volume bounded by the reflector. The space made available by placement of the collector within the volume bounded by the collector makes it possible to arrange the collection of fixed mirrors such that the scan beam experiences at least three reflections after leaving the spinner.

Steven J. Hammer - Lilburn GA, US

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06K007/10

US Classification:

23546232, 23546236, 23546238, 23546239, 2354624

Abstract:

A bar code scanner has a housing including a surface having a transparent scanning window. The housing contains optical components including a spinner and pattern mirrors arranged to produce sets of densely packed scan lines. The housing further contains a single output mirror which can be arranged in a first position in which the scan lines are optimized for horizontal scanning and a second position in which the scan lines are optimized for vertical scanning.

Inventors:

Steven J. Hammer - Lilburn GA, US

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06K007/10

US Classification:

2354624, 23546239, 23546232

Abstract:

A bar code scanner has a housing including a surface having a transparent scanning window. The housing contains optical components including a spinner mounted on a rotating motor; pattern mirrors and a collector for collecting light reflected from a bar code during scanning. Wherein the spinner is an inverted frusto-conical spinner with internal reflecting surfaces, the diameter of the spinner increasing as distance from the motor increases, and wherein the collector is mounted substantially within the body of the spinner.

International Classification:

G06K 15/00
G06K 7/10

US Classification:

23546213, 23546201

Abstract:

A checkout device including an element for shifting a scan pattern to an effective location for scanning. In addition to the optical element, the checkout device includes a bar code reader. The bar code reader includes a housing having an aperture for emitting scanning light beams. The checkout device further includes a security system in the housing and adjacent the aperture for deactivating security labels on scanned items.

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06K 7/10

US Classification:

23546239, 23546225

Abstract:

A bar code scanner with laser beam oscillator which rasters a laser beam to produce more scan line coverage. The bar code scanner includes a laser for producing a laser beam, a mirrored spinner, and a laser beam oscillator optically located between the laser and the mirrored spinner for continuously deflecting the laser beam about an undeflected path of the laser beam.

US Classification:

2354624, 23546236, 23546237, 23546238, 23546239

Abstract:

A barcode scanner with a dual-surface polygon which increases total scan line length. The polygon includes generally planar walls arranged in a ring having first mirrored facets facing generally towards a center of the ring and second mirrored facets facing generally away from the center of the ring. The first and second mirrored facets direct a laser beam to produce a scan pattern.

International Classification:

G06K 7/10
G02B 26/08

US Classification:

23546239, 359216
