Abstract

A bar code reader system is required to be integrated into an energy dispenser that is able to read a variety of bar code formats printed on a variety of media. The bar code reader system accepts both bar encoded cards having very low aspect ratios and other printed bar encoded media having differing aspect ratios. The system also provides a robust scanning pattern such that other printed bar encoded media can be placed into a receiving cavity without regard to a particular orientation. Further, the system provides a sensing mechanism capable of determining when a card has been inserted into the system or when another bar encoded media has been placed into the receiving cavity.

Claims

1. In an energy dispensing system, a bar code reading mechanism integrated with said energy dispensing system capable of reading a variety of bar code shapes and sizes in order to process a transaction, said bar code reading mechanism comprising:

(a) a bar code scanning unit coupled with said energy dispensing system for directing a plurality of scan beams into a readable area;

(b) a card guide having card guide rails on both sides of the readable area of the scanning unit, said card guide for accepting a bar encoded card and guiding said bar encoded card into the readable area of said scanning unit; and

(c) a receiving cavity for accepting other bar encoded media to be read and processed into the readable area of said scanning unit.

2. The system of claim 1 further comprising an optical sensor for activating said scanning unit upon detecting the insertion of a card in said card guide or other bar encoded media into the receiving cavity.

3. The system of claim 2 wherein said optical sensor is positioned immediately above a leading edge of both the card guide and the receiving cavity.

4. The system of claim 1 wherein the scanning unit radiates a plurality of scan beams in a geometric pattern such that the orientation of an inserted bar encoded media into said receiving cavity is inconsequential to its ability to be read and processed.

5. The system of claim 4 wherein said scan beams are reflected off a mirror within said energy dispensing device into the readable area of said scanning device.

6. The system of claim 5 further comprising a transparent shield within said energy dispensing device positioned above and substantially co-extensive with said card guide for the purpose of sealing the scanning unit from the outside environment.

7. The system of claim 1 wherein said receiving cavity has an inclined bottom surface for positioning an inserted bar encoded media at an angle.

8. The system of claim 7 wherein the geometry of said receiving cavity is such that a standard credit-card sized card can be inserted long edge first.

9. The system of claim 1 wherein said card guide further comprises an indentation sized to accommodate a customer'"'"'s thumb positioned above and centered substantially between said card guide rails, said indentation for facilitating insertion of said bar encoded card to its proper depth within said card guide while giving a customer sufficient room to retain a firm grasp of said bar encoded card.

10. The system of claim 1 wherein said card guide is substantially flush mounted to an exterior housing of said energy dispenser device such that said card guide is readily accessible to a customer.

11. The system of claim 1 wherein said receiving cavity is positioned beneath said card guide such that an opening of the receiving cavity allows a customer to insert bar encoded media therein.

12. In an energy dispensing system having an exterior panel suitable for customer interaction, a bar code reading mechanism integrated within said energy dispensing system capable of reading a variety of bar code shapes and sizes which is accessible to a customer via said exterior panel wherein a customer presents a bar encoded media to the bar code reading mechanism in order to process a transaction, said bar code reading mechanism comprising:

(a) a bar code scanning unit coupled with said energy dispensing system for directing a plurality of scan beams into a readable area where said customer places a bar encoded media;

(b) a card guide having card guide rails on both sides of the readable area of the scanning unit, said card guide for accepting a bar encoded card and guiding said bar encoded card into the readable area of said scanning unit wherein said card guide is fixed to the exterior panel of said energy dispenser device such that it is readily accessible to a customer; and

(c) a receiving cavity for accepting other bar encoded media to be read and processed into the readable area of said scanning unit wherein said receiving cavity is positioned beneath said card guide such that an opening of the receiving cavity allows a customer to insert bar encoded media therein.

13. The system of claim 12 further comprising an optical sensor for activating said scanning unit upon detecting the insertion of a card in the card guide or other bar encoded media into the receiving cavity, said optical sensor positioned immediately above a leading edge of both the card guide and the receiving cavity.

14. The system of claim 12 wherein the scanning unit radiates a plurality of scan beams in a geometric pattern such that the orientation of an inserted bar encoded media into said receiving cavity is inconsequential to its ability to be read and processed.

15. The system of claim 14 wherein said scan beams are reflected off a mirror fixed within said energy dispensing device into the readable area of said scanning device.

16. The system of claim 15 further comprising a transparent shield fixed within said energy dispensing device positioned above and substantially co-extensive with said card guide for the purpose of sealing the scanning unit from the outside environment.

17. The system of claim 12 wherein said receiving cavity has an inclined bottom surface for positioning an inserted bar encoded media at an angle that maximizes readability of the bar code.

18. The system of claim 17 wherein the geometry of said receiving cavity is such that a standard credit-card sized card can be inserted long edge first.

19. The system of claim 12 wherein said card guide further comprises an indentation sized to accommodate a customer'"'"'s thumb positioned above and centered between said card guide rails, said indentation for facilitating insertion of said bar encoded card to its proper depth within said card guide while giving a customer sufficient room to retain a firm grasp of said bar encoded card.
