Abstract: Systems and techniques for image based bar code scanning. A rotating spinner is positioned to reflect images to an imaging device within the scanner so that a field of view of the scanner encompasses images reflected by the spinner to the imaging device. The rotation of the spinner causes the field of view of the scanner to change. Fixed mirrors positioned and oriented to reflect images to the spinner and from the spinner to the imaging device further shift the field of view of the scanner as the rotating spinner causes images reflected from different mirrors to be delivered to the imaging device.

Mirrors positioned and oriented to reflect images to the spinner and from the spinner to the imaging device further shift the field of view of the scanner as the rotating spinner causes images reflected from different mirrors to be delivered to the imaging device so that both cashier and customer side imaging sensing may be employed. The image field may be automatically shifted from cashier side imaging to customer side imaging, shifted based on detection of customer presentation of an item in a customer presentation window field of view, or manually shifted by a cashier.

Abstract: Methods and apparatus for switching between scan patterns produced by a barcode scanner and for switching between allowing and inhibiting decoding of barcodes are disclosed. Depending on the position of a multiposition switch controlled by an operator, the scanner produces an omnidirectional scan pattern and immediately decodes barcodes falling within the field of view of the scanner, produces a single line scan pattern but inhibits decoding of barcodes until the switch is moved to a position to select allowing decoding of barcodes, or produces a single line scan pattern and immediately decodes barcodes falling within the field of view of the scanner. If the scanner has been set to decode barcodes using a single line scan pattern, a delay is imposed between the time the switch is set to select producing an omnidirectional scan pattern and the time at which the scanner begins to produce the omnidirectional scan pattern.
