Abstract

A method and means for automatically inventorying items having coded tags or labels using a character-recognition device, such as a wand scanner, in combination with a system for specially marking the labels when they have been successfully read and recorded by the scanner, which system comprises the use of a photosensitive dye-forming material on the label and an ultraviolet light-producing flash device on the scanner. The flash device is actuated upon the successful completion of a recognition reading and irradiates the label with ultraviolet light which produces a visible and permanent mark on the label.

Claims

1. A method for providing a visible verification of the performance of an inventory operation on an item comprising the steps of:

disposing on the surface of an item to be inventoried information relating to said item in combination with a photosensitive material which undergoes a visible change upon being irradiated with appropriate light;

performing an inventory operation on said item by recording the information relating to said item; and

upon the completion of the recordation of said information, producing a visible change in the photosensitive material by irradiating said material with said appropriate light to verify the performance of the recording step on the item.

2. Method as in claim 1 wherein said photosensitive material is a free-radical dye-forming system.

3. Method as in claim 2 wherein the appropriate light is produced with a Xenon flash tube.

4. Method as in claim 1 wherein said recording step is performed with a wand scanner.

5. Method as in claim 1 wherein said information is printed on a paper having said photosensitive material on the surface thereof.

6. Method as in claim 5 wherein said paper comprises a label.

7. Method as in claim 1 wherein said photosensitive material is DYLUX.

8. A system for providing a visible verification of the performance of an inventorying operation on an item comprising in combination:

means on the surface of said item for marking said item comprising;

means for providing information relating to said item; and

photosensitive means for changing visibly upon being irradiated with appropriate light;

means for recording said information in an inventorying operation;

means, responsive to the completion of the recordation of said information by said recording means, for irradiating said photosensitive means with said appropriate light to visibly change said photosensitive means thus verifying the performance of the inventorying operation.

9. The system of claim 8 wherein said photosensitive means comprises a free-radical dye-forming system.

10. The system of claim 9 wherein said irradiating means comprises a Xenon flash tube.

11. The system of claim 8 wherein said recording means comprises a wand scanner.

12. The system of claim 11 wherein said irradiating means is mounted on said wand scanner.

13. The system of claim 8 wherein said information means comprises a printed paper and said photosensitive means is coated or imprinted thereon.

14. A system for automatically producing a record for an item in combination with a visible verification on the item of the production of the record comprising:

label means for marking an item to be recorded, said label means comprising;

means for containing information relating to said item; and

photosensitive dye-forming material;

means for recording from said label means said information relating to said item;

means for producing a signal upon the completion of the recording of said information by said recording means;

means responsive to said signal for irradiating said photosensitive dye-forming material with ultraviolet light to change the color thereof whereby a visible verification appears on said label means of the completion of the recording operation;

computer means for receiving said recorded information and producing an output signal in accordance therewith; and

printer means responsive to the output signals of said computer means for printing out a record of said information.

15. The system of claim 14 wherein said recording means comprises a wand scanner.

16. The system of claim 15 wherein said irradiating means is mounted on said wand scanner.

17. The system of claim 16 wherein said irradiating means comprises a Xenon flash tube.

18. The system of claim 14 wherein said label means comprises a shipping label and said printed record comprises a bill of lading.

19. The system of claim 15 wherein said computer means comprises a minicomputer and a modem interface.

20. The system of claim 15 wherein said signal producing means comprises a minicomputer.

21. A method for providing a visible verification of the performance of an inventory operation on an item comprising the steps of:

disposing on the surface of an item to be inventoried information relating to said item in combination with a radiating energy sensitive material which changes visibly upon being irradiated with appropriate radiating energy;

performing an inventory operation on said item by recording the information relating to said item; and

upon the completion of the recordation of said information, producing a visible change in the radiating energy sensitive material by irradiating said material with said appropriate radiating energy to verify the performance of the recording step on the item.

22. A system for providing a visible verification of the performance of an inventorying operation on an item comprising in combination:

means on the surface of said item for marking said item comprising;

means for providing information relating to said item; and

radiating energy sensitive means for changing visibly upon being exposed to appropriate radiating energy;

means for recording said information in an inventorying operation;

means, responsive to the completion of the recordation of said information by said recording means, for exposing said radiating energy sensitive means to said appropriate radiation energy to visibly change said radiating energy sensitive means thus verifying the performance of the inventorying operation.
