Abstract

File folders are provided with unique machine-readable indicia representing the contents therein. Scanners sensitive to the machine-readable indicia are mounted to filing cabinets so that, upon opening or closing a drawer, the indicia on the folders within that drawer are automatically scanned. The indicia scanned are then input to a computer system that logs the scanned folders as being located in that drawer.

Claims

1. An automated file locator system for at least one file holder, said file holder having a housing and at least one folder carrier for holding a plurality of folders, said folder carrier being movable between an open and a closed position, comprising:

a machine-readable code mounted on each of said folders;

at least one code-reading means mounted on said housing adjacent said carrier, said code-reading means positioned on said housing such that movement of said carrier between the open and closed positions causes said code-reading means to automatically scan the machine-readable codes on said folders, said code-reading means generating signals corresponding to said codes in response to the scanning thereof; and

control means for receiving the signals from said code-reading means and indicating that a folder with a particular code is located in said folder carrier.

2. A file locator system as in claim 1 wherein said file holder has a plurality of folder carriers.

3. A file locator system as in claim 2 wherein the code on each of said folders is unique.

4. A file locator system as in claim 3 wherein said folder carriers are drawers and said file holder is a file cabinet.

5. A file locator system as in claim 4, said system having a plurality of file holders, each file holder having at least one indicator connected to said control means.

6. A file locator system as in claim 5 wherein said control means is an electronic data storage and retrieval means.

7. A file locator system as in claim 6 wherein said data storage and retrieval means is at least one computer connected to a memory device.

8. A file locator system as in claim 7 wherein said file folders are hanging folders, said folders suspended transverse to a direction of travel of said drawers.

9. A file locator system as in claim 8 wherein said machine readable code is a bar code, said code being embedded in an interchangeable tab attached to a top surface of said folders.

10. A file locator system as in claim 7, said code-reading means having two indicators for receiving signals from said control means and a button for sending control signals to said control means.

11. A file locator system as in claim 10, wherein one of said indicators is energized by said control means when a particular folder in said carrier is adjacent said code-reading means on which said one of said indicators is mounted.

12. A file locator system as in claim 4, wherein each of said at least one code-reading means is an infrared scanner.

13. A file locator system as in claim 12, wherein each of said at least one scanner is located above a corresponding one of said drawers on the exterior of said housing.

14. A file locator system as in claim 12, wherein each of said at least one scanner is located above a corresponding one of said drawers on the interior of said housing.

15. A file locator system as in claim 12 wherein said machine-readable code is a bar code.

16. A file locator system as in claim 1, further comprising a carrier-mounted machine-readable code mounted within each carrier, said carrier-mounted code being scanned along with said machine-readable code, and stored by said data storage and retrieval means.

17. An automated file locator system for a plurality file cabinets, each of said file cabinets having a housing and a plurality of drawers for holding a plurality of folders, said drawers being movable between an open and a closed position, said folders comprising hanging folders suspended transverse to a direction of travel of said drawers, said system comprising:

a unique machine-readable code mounted on each of said folders, wherein said machine readable code is a bar code embedded in an interchangeable tab attached to a top surface of said folders;

at least one code-reading means mounted on said housing adjacent a corresponding drawer, said at least one code-reading means positioned on said housing such that movement of said drawer between the open and closed positions causes said code-reading means to scan the machine-readable codes on said folders, said code-reading means generating signals corresponding to said codes in response to the scanning thereof;

at least one computer connected to a memory device for receiving the signals from said code-reading means and indicating that a folder with a particular code is located in said drawer, each of said file cabinets having at least one indicator connected to said at least one computer; and

at least one remote code-reading means mounted remote from said housing and outputting signals to said at least one computer when said bar code on one of said folders passes by one of said remote code-reading means.

18. A file cabinet for use in an automated file locator system having a plurality of file folders, said folders each having a machine-readable code, comprising:

at least one folder carrier, said carrier movably mounted within said cabinet; and

at least one code-reading means mounted adjacent said carrier and positioned to automatically read said codes in response to movement of said carrier within said housing.

19. A method of processing file location information, comprising the steps of:

(a) providing a cabinet having at least one drawer and a scanner adjacent to said drawer;

(b) providing at least one file folder having a machine-readable code;

(c) automatically scanning said code in response to movement of said drawer in said cabinet, such that said code passes said scanner, said scanner producing signals corresponding to said code;

(d) storing said signals and said location; and

(e) outputting said code and said location.

20. The method of claim 19 which further comprises mounted at least one remote code-reading means remote from said file cabinet, and outputting said code and said location from the remote code-reading means to a computer when one of said folders passes by said remote code-reading means.

21. An automated file locator system for a file cabinet having a housing and a plurality of drawers for holding a plurality of folders, said drawers being movable between an open and a closed position, said folders comprising hanging folders suspended transverse to a direction of travel of said drawers, said system comprising:

a unique machine-readable code mounted on each of said folders;

at least one code-reading means mounted on said housing adjacent a corresponding drawer, said at least one code-reading means positioned on said housing such that movement of said drawer between the open and closed positions causes said code-reading means to scan the machine-readable codes on said folders, said code-reading means generating signals corresponding to said codes in response to the scanning thereof;

at least one computer connected to a memory device for receiving the signals from said code-reading means and indicating that a folder with a particular code is located in said drawer, each of said file cabinets having at least one indicator connected to said at least one computer; and

at least one remote code-reading means mounted remote from said housing and outputting signals to said at least one computer when said bar code on one of said folders passes by one of said remote code-reading means.

22. The system of claim 21 wherein the code mounted on each folder is a bar code embedded in an interchangeable tab attached to a top surface of the folder.

23. The system of claim 21 wherein the code is automatically scanned by the code-reading means in response to movement of the drawer in the cabinet.

24. An automated file location system comprising:

a plurality of drawers;

a plurality of scanners, each of said scanners adjacent to a corresponding one of said drawers; and

a plurality of file folders wherein each drawer contains at least one of said file folders, each of said file folders having a detachable tab on a top surface of said folder, wherein a machine-readable code is formed on said tab, said code supplying information to said system through one of said scanners when one of said drawers is moved past said one of said scanners.
