Abstract
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 Analysis
Total Claims: 23
Claim 1
Independent Claim
182 words
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.
Claim 2
Dependent Claim
182 words
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.

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.
Claim 7
Dependent Claim
27 words
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.
Claim 8
Dependent Claim
57 words
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.
Claim 9
Independent Claim
250 words
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.
Claim 10
Independent Claim
250 words
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.
