Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.

A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.
摘要:
An optical scanner for reading indicia such as barcode symbols is usable in a first, hand-held mode and in a second, hands-free mode in which the scanner is mounted to a fixed stand. Switching means are provided so that when the scanner is lifted from the stand, for hand-held use, it automatically switches to a first working range, and when it is replaced onto the stand it automatically switches to a second, closer, working range. In the first working range, the software is optimised to read barcode symbols at a relatively long distance from the scanner; in the second working range the software is optimised to read barcode symbols which are relatively close to the scanner. The switching means may comprise any type of contact or non-contact switch such as a reed switch or a Hall effect switch.

A solid-state imager and an electro-optical reader are mounted behind respective windows at a point-of-transaction workstation for capturing images of diverse targets useful for customer identification, customer payment validation, and operator surveillance, and for reading coded indicia. Each window allows light to pass therethrough to only one of the reader and the imager.
摘要:
The invention relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system, Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.
摘要:
An arrangement for decoding a bar code symbol in which the data resulting from scanning a bar code symbol with a bar code scanner is evaluated to determine if the scanned bar code symbol is within the working range of the scanner. The data acquired by the bar code scanner is evaluated to determine if the detected widths of the bars and spaces of the scanned bar code symbol are too small, less than a threshold value, which indicates that the bar code symbol is too far and outside of the working range of the scanner. Moreover, the working range of the bar code scanner can be selectively changed by changing the threshold value, which can be easily implemented by having the bar code scanner scan a menu bar code which instructs the decoder to change the threshold value to a selected new value which may be pre-established for the particular operation. The arrangement preferably includes software to process the data acquired by the bar code scanner, and if the data indicates that the scanning distance to the bar code is too far, a flag is set in the software which prevents a new decode result from being recorded. However, the intermediate decode result is retained in memory to indicate that the bar code symbol is still in the scanner's field of view. A second evaluation validation to determine if the detected bar code symbol is valid may also be performed.
摘要:
A consumer can use his or her cell phone to scan barcodes from newspaper circulars at home, on a computer screen at home and/or to scan coupon barcodes positioned on the edge of shelves in a store or displayed on a kiosk in a store. The data from all these coupons is be combined into (preferably) a single 2D barcode or in the event of a large number of coupons, into a smaller number of 2D barcodes on the cell phone's display, for scanning by an imaging barcode scanner at the point of sale. This 2D barcode can also include the user's loyalty card information, so reading a single barcode off the screen of the phone can accomplish what formerly required multiple individual scans to accomplish.
