Abstract

The present invention provides a manually controlled wand which is particularly suited for use in a file control system in which the files are provided with machine readable codes located along an edge of the file. The wand is adapted by the provision of a jig used to bear against the edge of the file for locating the wand in a read position over the code and riding along the file edge to guide and steady the manual movement of the wand to provide an accurate reading of the code.

Claims

1. A hand-held wand adapted for accurate machine reading of a machine readable code provided on an article with a generally flat edge region having a substantially straight peripheral edge with the machine readable code running generally parallel to such peripheral edge fixed relative thereto, said wand having a precise scan field through a read window requiring a substantially exact locating over the code for reading thereof, said wand being provided with jig means projecting beyond said read window to form an open step-like construction with said jig means being at a substantially 90 degree angle with said read window whereby when the edge region is placed in a horizontal position said jig means extends downwardly over and bears against the peripheral edge to locate said read window over the code, said jig means being of a length to provide a horizontally extended generally upright contact with the peripheral edge to guide movement of said wand and to resist horizontal pivoting of said read window over the code as said jig means rides along the peripheral edge of the horizontally positioned edge region.

2. A handheld wand as claimed in claim 1 adapted for accurate reading of a machine readable optically recognizable code of about 0.1 inches in height.

3. A hand held wand as claimed in claim 2, wherein said jig means is located below the read window for engaging the guide edge from below and for machine reading of the code by said wand from above the edge and jig means.

4. A hand held wand as claimed in claim 2 wherein said jig means is located above the read window for engaging the guide edge from above the code for machine reading of the code by said wand from below the jig means.

5. A file control system as claimed in claim 1, wherein said jig means presents a flat face extending forwardly from the wand and being of a length to bear against a substantial portion of the file edge to prevent pivotal movement of the wand when in the read position, said flat face having at least one edge region which curves rearwardly away from the scan field in the direction of travel of the wand to provide a camming arrangement for camming the jig means over the label for avoiding damage to the label.

6. A hand-held wand as claimed in claim 1 wherein said jig means comprises a flat faced jig which is elongated in direction of travel of said wand.

7. A hand-held wand as claimed in claim 1 when used in a system for identifying the article and the recording location information regarding the article, said wand being connected to recording means which automatically records the location information after the article has been identified, said recording means having a memory for storing and retrieval of such information.

8. A system for identifying and recording whereabouts of a file having a machine readable code provided on a generally flat edge region of the file and running essentially parallel with and fixed relative to a substantially straight peripheral edge of such region, said system comprising a hand-held wand adapted for accurate machine reading of such code and having a precise scan field through a read window requiring a substantially exact locating over the code for reading thereof, said wand being provided with jig means projecting beyond said read window to form an open step-like construction with said jig means being at a substantially right angle with said read window whereby when the file is placed such that the edge region is in a horizontal position said jig means extends downwardly over and bears against the peripheral edge to locate said read window over the code, said jig means being of a length to provide a horizontally extended generally upright contact with the peripheral edge to guide movement of said wand and to resist horizontal pivoting of said read window over the code as said jig means rides along the peripheral edge of the horizontally positioned edge region;

said wand being located at a control station of predetermined fixed location, said system further comprising recording means which is adapted to automatically record readily retrievable locating information regarding the file from said control station, said system further being provided with means for indicating a proper machine reading of the machine readable code.

9. A system as claimed in claim 8, wherein said wand has an initial scan field of about 0.4 inches which narrows during machine reading of the code to about 0.3 inches, said jig means, when bearing against the file edge, preventing movement of the wand out of the read position.

10. A system as claimed in claim 8, wherein said jig means is located below said read window such that said wand is particularly suitable for reading a machine readable code running along a side edge of the file.

11. A system as claimed in claim 8, wherein said jig means is located above said read window such that said wand is particularly suitable for reading a machine readable code running along a top edge of the file.

12. A system as claimed in claims 9, 10 or 11, wherein said jig means is adjustably secured to said wand to adapt said wand for use on other files having different spacings between the machine readable code and the file edge with which the jig is engaged.

13. A system as claimed in claim 8, wherein said control station includes a visual display which automatically displays the code, as machine read by the wand for visual verification thereof.

14. A system as claimed in claim 8, wherein said system is adapted to identify a preselected fixed number of machine readable characters in the code for a valid machine reading thereof, said control station having an audible indicator to indicate when the fixed number of machine readable characters have been machine read and to audibly advise the valid machine reading of the code.

15. A system as claimed in claim 14, wherein said characters are about 0.1 inches in height, said machine reader having an initial scan field of about 0.4 inches which narrows during machine reading of the code to about 0.3 inches leaving a maximum tolerance of about 0.1 inches above and below the characters.

16. A file control system as claimed in claim 8 wherein said machine readable code is provided on a label with said label being applied along the edge of the file.

17. A file control system as claimed in claim 16, wherein said label is adapted for accurate manual application along the edge of the file to assist in positioning the machine readable characters in the substantially straight line running essentially parallel to the edge of the file.

18. A file control system as claimed in claim 17 wherein said label comprises a body portion having a forward surface on which said characters are provided and a sticky back surface covered by a backing mterial, said backing material being scored near the edge thereof to permit removal of a small strip of the backing paper for exposing a portion of the sticky back surface which is used to accurately locate the label in position, the remainder of the backing paper being removable to thereafter fully secure the label in the accurately located position.

19. A file control system as claimed in claim 17 wherein said machine readable characters are about 0.1 inches in height and wherein the scan field of the wand is about 0.3 inches providing a tolerance of about 0.1 inches to either side of the characters.

20. A system as claimed in claim 8 wherein the locating information is only recorded based on a valid machine reading of the code and including means for sensing such valid machine reading.

21. A system as claimed in claim 8 wherein said machine readable code is in the form of a plurality of optically recognizable and machine readable characters.
